With the thermal design power (TDP) of NVIDIA GB200 superchip exceeding 1200 watts per rack, an efficient liquid cooling system becomes crucial. Lori has provided fully customizable cold plate components, which are specifically designed for the NVIDIA GB200 liquid cooling architecture. These components ensure optimal contact temperature, uniform flow, and long-term reliability in high-density AI data centers.
Core features:
1. Tailored Baseplate Geometry for GB200 Placement
Direct-mapped cooling zones for GPU, CPU, and HBM chiplets
Step-machined surface to match the GB200’s height variations (±0.05 mm tolerance)
2. High-Performance Micro-Channel & Pin-Fin Arrays
Hydraulic diameter optimized for low-flow resistance
CFD-validated fin patterns that reduce thermal resistance to ensure the reliable heat disspistation capibility
3. Material Selection for Long-Term Reliability
Copper (C11000) or nickel-plated aluminum – corrosion-resistant with dielectric coolant compatibility
Lori liquid cooling loops have been fully tested and validated to ensure optimal quality and cooling performance.
Leakage detection in Lori vacuum brazing liquid cooling circuits utilizes vacuum technology and the unique properties of helium for high reliability, ensuring no leakage risk in our liquid cooling.
Lori direct liquid cooling circuit has been tested by ultrasonic scanning microscope, which can clearly reflect the internal structure of the loop and strictly control the product quality.
Lori liquid cooling component forms a chemical passivation film by cleaning the internal flow channels through pipelines, which can effectively prevent the recurrence of dirt, protect the equipment from corrosion or other chemical damage, ensure equipment safety and extend its service life.

Lori liquid cooling components will undergo comprehensive leakage detection to ensure that there is no leakage in the internal flow channels and connection points of the liquid cooling plate, preventing coolant leakage and ensuring the stable operation of the equipment.
Q1: What are the main advantages of your liquid cooling solution compared to traditional air cooling?
A: Our liquid cooling solution provides targeted cooling directly to heat-generating cores (such as CPUs/GPUs), achieving efficiency several times higher than air convection.
This enables servers to sustain turbo frequencies at higher power levels, increasing compute density while significantly reducing overall data center energy consumption (PUE).
Q2: How does vacuum brazing differ from traditional welding?
A: Vacuum brazing occurs in an oxygen-free vacuum furnace, eliminating oxidation and impurities. It forms seamless, uniform, and high-strength metallurgical bonds without melting the base material.
Compared to traditional welding, brazed joints are smoother with lower flow resistance and fundamentally eliminate the risk of micro-leaks, ensuring absolute circuit integrity during long-term operation.
Q3: Is this liquid cooling circuit “plug-and-play”?
A: Yes, we provide a highly integrated module. It is factory-tested as a complete unit designed to simplify your integration process. You receive a pre-assembled cooling circuit, significantly reducing the time
and risk associated with manually assembling multiple components inside the server.
Q4: What is the design process for custom cold plates?
A: The process begins with close collaboration. You provide the mechanical layout of the target server and its Thermal Design Power (TDP) requirements. Our engineering team then creates 3D models,
performs thermal simulations, and presents a customized cold plate design for your approval, ensuring perfect compatibility with your hardware.
