Lori is actively engaging in addressing the escalating cooling requirements in the high-performance computing sector, particularly for chips and servers that power cutting-edge AI technologies. As energy consumption emerges as a major obstacle in enhancing computational capabilities, Lori has become one of many component manufacturers dedicated to developing efficient liquid cooling solutions tailored for AI data centers.The focus in this domain lies on AI data centers relying on powerful graphics processors from companies like NVIDIA or similar vendors, capable of executing parallel computing tasks crucial for enabling applications like ChatGPT and similar generative AI. However, the power consumption demands of these chips are soaring, jumping from early 400 watts to 700 watts and potentially reaching 1000 watts in the future, far exceeding the energy consumption levels of ordinary consumer electronics.Lori has invested heavily in liquid cooling systems aimed at resolving the immense heat generation issues in AI data centers. With the market's surging demand for graphics processing units (GPUs) used in AI model training, the power management and cooling solutions industry, previously seen as a peripheral segment of the supply chain, is now receiving unprecedented attention.As chip power consumption increases drastically, cooling has become a critical factor limiting performance. Temperature directly impacts chip operating efficiency, necessitating more sophisticated cooling technologies than ever before. Traditional air-cooling methods based on fans and ducts are struggling to meet the cooling demands of AI servers.Simultaneously, as the tech industry strives to achieve net-zero emission goals, cooling technologies are crucial for data center operators to maintain low power usage effectiveness (PUE). Emerging technologies include liquid cooling and immersion cooling, where the former involves a water system flowing around servers to reduce temperature, and the latter submerges the entire server rack in a non-conductive liquid.Traditional cooling methods have failed to meet the challenges posed by AI. Comparative tests have shown that chips using air-cooling techniques can only reach 60% of their performance and face overheating risks, whereas liquid cooling solutions can continuously optimize computational performance.Facing future AI computing demands, Lori believes that "new liquid cooling technologies will become crucial solutions, replacing the current mainstream but less efficient air-cooling methods." Market analysts also point out that the energy consumption of AI servers has surpassed the limits of air-cooling technologies, driving the demand for more complex and efficient cooling technologies, such as water or liquid cooling. With the continually growing market share of AI servers, this trend is expected to accelerate.To address the cooling needs of AI servers, Lori has introduced a customized liquid cooling loop thermal management solution for servers.Lori's liquid cooling loop employs advanced fluid dynamics principles, using precision piping systems to directly deliver coolant to the vicinity of each heat-generating component, achieving efficient and precise heat transfer. This loop not only enhances cooling efficiency but also extends hardware lifespan, featuring high reliability and ease of maintenance, providing robust technical support for AI data centers.

As modern computing devices become increasingly powerful, the energy consumption of data centers, supercomputers, and servers continues to rise, making heat dissipation a critical issue. Traditional air cooling methods are proving inadequate for high-density computing needs, leading to the emergence of liquid cooling technologies. Liquid cooling primarily falls into two categories: Direct Liquid Cooling (DLC) and Immersion Cooling. While both methods use liquid to dissipate heat from equipment, their principles, applications, and advantages differ significantly.Working PrinciplesDirect Liquid Cooling (DLC)DLC involves installing liquid cooling plates or heat exchangers on key components (such as CPUs, GPUs, or power modules) within computing devices. Liquid circulates through these coolers, directly contacting heat-generating parts to remove heat. The coolant is typically transported through pipes to cooling devices and recirculated. This method enhances thermal management by combining liquid cooling with traditional air cooling, improving heat dissipation efficiency.            Immersion CoolingImmersion cooling involves completely submerging the entire computing device (such as a server) in a specialized insulating liquid. The liquid directly contacts all hardware, enabling comprehensive heat exchange. Since immersion liquids are usually non-conductive, they can safely interact with electronic components without damaging them. This approach eliminates the need for fans and other traditional air circulation systems.            1.Thermal Efficiency ComparisonDirect Liquid CoolingDLC can target specific heat-generating components, allowing for efficient localized cooling. Compared to air cooling, liquid has better thermal conductivity, and DLC can effectively lower the temperature of core components in high-performance computing environments. While it provides a significant improvement over air cooling, it still requires consideration of overall system heat management, especially for parts not covered by liquid cooling. Immersion CoolingImmersion cooling achieves exceptional thermal efficiency because the entire device is submerged in liquid, allowing for uniform heat distribution. This makes immersion cooling particularly effective in extreme high-temperature workloads, as it can manage thermal distribution more comprehensively than DLC. In high-power, high-density scenarios, immersion cooling typically outperforms direct liquid cooling.2.System Complexity and MaintenanceDirect Liquid CoolingDLC systems are relatively complex, requiring the installation and maintenance of liquid cooling pipes, cooling plates, pumps, and heat exchangers. Although the liquid does not directly contact all components, a highly sealed cooling system is necessary to prevent leaks. Regular maintenance can be intricate, and since DLC still relies on some air cooling, the overall layout requires careful design.Immersion CoolingImmersion cooling systems tend to be simpler in structure, as they lack complex components like cooling pipes and heat sinks. However, they require careful selection and periodic replacement of the cooling liquid. Since all devices are submerged, maintenance involves removing and drying equipment, which can add to the workload. Unlike DLC, immersion cooling liquids may need to be replaced regularly, especially as they absorb heat over time or degrade with prolonged use.3.Application ScenariosDirect Liquid CoolingDLC is suitable for environments that require efficient cooling without completely abandoning air cooling systems, particularly where precise cooling of critical components is necessary. This includes data centers and high-performance computing devices, especially those running intensive workloads, where DLC can help maintain stable temperatures and extend equipment lifespan.Immersion CoolingImmersion cooling is ideal for higher power and density devices, particularly in extreme environments, such as large data centers or supercomputers requiring continuous, efficient cooling. For high-performance, always-on workloads (such as AI training or cryptocurrency mining), immersion cooling is particularly attractive due to its ability to significantly reduce energy consumption and cooling equipment footprint.4.Energy Consumption and CostDirect Liquid CoolingDLC can significantly lower energy consumption compared to air cooling, especially in handling high-power devices. While installation costs can be high,particularly for liquid cooling modules, the overall energy expenditure and operational costs tend to be lower during operationImmersion CoolingImmersion cooling requires a higher initial investment, especially for the purchase of specialized cooling liquids and system setup. However, due to its exceptional cooling efficiency, it can lead to substantial energy savings in the long run. Additionally, the ability to increase equipment density can save space and reduce operational costs in data centers.  ConclusionIn comparing direct liquid cooling and immersion cooling, each has its own strengths. Direct liquid cooling excels in system complexity and targeted cooling, making it suitable for environments that require precise cooling while still utilizing some air cooling. In contrast, immersion cooling offers superior thermal efficiency and energy optimization, especially for high-density, high-power applications. Ultimately, the choice should depend on specific application needs, system power consumption, and long-term cost considerations.

Data centers can generate a significant amount of noise. Why? Because noise is a byproduct of traditional data center operations. Hundreds of servers (more in hyper-scale data centers) running simultaneously in a compact space can produce a lot of noise. It is estimated that the average noise level around servers can reach 92 A-weighted decibels (dBA). Not to mention the noise generated by the equipment typically needed to keep servers cool.Research shows that HVAC systems running continuously can produce noise levels exceeding 80 dBA, nearing the maximum acceptable threshold of 85 dBA set by the National Institute for Occupational Safety and Health for 8-hour exposure. As the density and power of data centers increase, the global demand for greater computing power continues to grow, escalating the cooling needs of data centers. We need new cooling methods, and noise control should also be a consideration for data centers.One increasingly popular alternative is immersion cooling, which involves submerging all computer components in an insulating liquid to maintain ideal operating temperatures. As a practical solution to the thermal issues of data centers, this technology is being adopted more widely.Moreover, immersion cooling is quiet, potentially eliminating the hum generated by HVAC systems while providing a range of other benefits for your operations. In an era of labor shortages, creating a safe work environment where employees can thrive becomes a key advantage. Noise: A Potential Hazard in Your WorkplaceAccording to NIOSH, occupational hearing loss is one of the most common occupational diseases, which can be permanent. Furthermore, the organization estimates that about 22 million American workers are exposed to hazardous noise levels each year. The consequences of this are significant. Hearing loss is associated with difficulties in communication, as well as other health issues such as tinnitus, heart problems, cognitive decline, and mental health challenges. Therefore, excessive noise poses a real health and safety threat in your facility.Additionally, noise can lead to inefficient data center operations, including:- Communication problems among technicians, potentially resulting in poor operational outcomes.- Increased stress that disrupts focus, leading to lower work quality or operational safety issues.- Reduced productivity and increased absenteeism.By eliminating the continuous noise associated with typical HVAC systems, data centers can alleviate these issues, creating a quieter, calmer, and healthier workplace. Benefits of Immersion Cooling for Data CentersIn addition to reducing noise levels associated with traditional HVAC systems, immersion cooling offers other advantages:- Increased Power Density: Immersion cooling allows data centers to accommodate and maintain server infrastructure for higher computing density to meet growing demands.- Improved Thermal Performance: Systems using effective thermal management fluids can reduce throttling or downtime of equipment.- Enhanced Power Usage Efficiency: Immersion cooling eliminates the need for energy-consuming air cooling systems, allowing equipment to transfer more power consumption directly to the hardware.- Increased Sustainability: Single-phase immersion cooling uses less water than other cooling solutions/technologies and does not rely on carbon-fluorine based liquids (commonly used in two-phase cooling), which may exacerbate global warming and adversely affect chemical reactivity.- Environmental Adaptability: Immersion cooling does not require the introduction of outside air to cool IT equipment, allowing data centers to be built in any geographical location.Today's data center operators need to accomplish more work with less energy, smaller physical space, and shorter downtime, while considering the environmental impacts of data centers. Immersion cooling provides a long-term solution to address the thermal issues plaguing modern data centers.Interested in Learning More?Lori’s immersion cooling solution offers thermal management performance, addressing the limitations of today’s air cooling methods for data centers, enabling increased computing density while creating a happier, healthier work environment.

Experts predict that liquid cooling and immersion cooling technologies employed in data centers are entering a pivotal stage of development. A recent 2024 trend report indicates that liquid cooling will transition from a 'futuristic' concept to an indispensable 'necessity', occupying an increasingly important position in data center design.This shift is underpinned by several established factors, which are expected to peak this year. As server infrastructure continues to enhance its performance, the heat generated far exceeds that of previous IT equipment, an inevitable trend. Increasing evidence suggests that traditional cooling methods may struggle to maintain the necessary cooling levels for data centers to operate optimally.Therefore, data centers and their operators urgently need to proactively adopt new cooling solutions, including immersion cooling. Below are the reasons why immersion cooling is essential:Why is Immersion Cooling Important?By immersing IT equipment in a cooling dielectric fluid, immersion cooling technology demonstrates exceptional thermal conductivity, higher power density, and improved electrical energy efficiency. Properly deployed immersion cooling systems can reduce downtime, enable data centers to host and maintain denser server architectures, and enhance the power utilization efficiency of IT hardware.Why is This Moment Crucial?Immersion cooling technology is well-established, with a reliable track record and the trust of numerous leading companies in the technology industry. So, why is it receiving increasing attention now? Why should data center owners, operators, and managers seriously consider transitioning?Part of the reason lies in the fact that traditional air-cooling methods are struggling to effectively address the cooling demands of increasingly powerful server infrastructures. The thermal design power (TDP) of next-generation processing units can reach up to 350 watts, while the current typical server rack power density is approximately 7 kW, and the industry is striving to achieve a density of 20 kW per rack (multiple servers consist of one rack). For data centers with continuously enhanced functionalities, excellent cooling technology has become a necessity.For data centers, inadequate cooling systems are not viable options. Cooling failures are a common cause of data center outages, accounting for 13% of all outages annually according to Uptime Institute. With the increase in heat generation from infrastructure, this proportion is expected to continue rising. Furthermore, 70% of data center outage incidents cost $100,000 or more, and 25 percent cost more than $1 million.Clearly, cooling failures can damage corporate revenues, and this threat is growing. Therefore, data center owners, operators, and managers should take immediate action to incorporate new cooling technologies such as immersion cooling into their current and future plans.Why is Strategic Deployment Crucial?Transitioning to immersion cooling technology presents a fantastic opportunity for data center operations to adapt to future developments. Meanwhile, partnering with the right collaborators is a key way to fully leverage its advantages.An expert told Data Center Knowledge at the end of 2023, "Proper deployment of immersion cooling requires a comprehensive redesign of the data center. Therefore, although we expect to see 'temporary improvement solutions' within the next year, I predict that ultra-large-scale data center operators will prioritize and take necessary measures to strategically incorporate liquid cooling into their data center construction."For ultra-large-scale data centers, adopting immersion cooling offers unique advantages, but strategic deployment helps maximize processing potential within limited space. Suitable solutions can make more efficient use of the space occupied by traditional cooling equipment. By adopting the right strategies, more server infrastructure can be designed and deployed within existing space. Regardless of the size of the data center operation, immersion cooling can help better prepare for the future.Strategic deployment also involves evaluating alternative fluids. Early immersion cooling fluids were typically base oils directly procured from refineries, originally intended for other applications and industries, later adapted for use in data center cooling systems. Nowadays, immersion cooling fluids specifically formulated and developed for the unique needs of data centers offer optimized performance characteristics and better material compatibility. Additionally, with increasing power demands, the new generation of cooling fluids is expected to extend the expected lifespan of hardware.If you are interested in immersion cooling and wish to learn more, now is the best time – Lorithermal is ready to provide you with full support.Our immersion cooling fluid solutions can help data centers of any location and size achieve efficient cooling and improve operational efficiency.
