I. Aspects to Consider in the Design of Liquid Cold Plate Heat Sink

1. Heat Dissipation: Heat dissipation is one of the most crucial factors in the design of a liquid cold plate heat sink. The greater the heat dissipation, the better the cooling effect. Therefore, when designing a liquid cooling plate, comprehensive consideration must be given to the materials used, manufacturing processes, the number, length, and diameter of the cooling channels, etc., to achieve optimal heat dissipation.

2. Flow Rate: Flow rate refers to the speed and volume of water flow within the liquid cold plate. Faster water flow generally improves the cooling effect. However, excessive flow speed can lead to increased water pressure and temperature. Thus, the design must balance the relationship between flow rate and pressure, considering factors such as volume, channel length, and wall materials to adjust to the optimal flow rate.

3. Material of Liquid Cooling Plates: The material of the liquid cooling plates should have high thermal conductivity, good mechanical strength, and compatibility with water. Common materials include copper, aluminum, and titanium alloys. When selecting materials, factors such as thermal conductivity, mechanical strength, corrosion resistance, and processing costs should be considered.

4. Strength Design: Strength is a critical aspect of designing a liquid cold plate heat sink to prevent leakage or seepage during actual use. The design should account for various load conditions based on the electronic equipment, controlling factors like material thickness, hole shapes, hole spacing, and support structure design to ensure the cold plate can withstand all operational loads.

II. Standards for the Design of Liquid Cold Plate Heat Sink

1. Heat Dissipation Efficiency: The heat dissipation efficiency of the liquid cold plate heat sink should meet certain standards, generally above 80%. If the efficiency is below 80%, it indicates a design flaw that requires redesign.

2. Water Flow Speed: The water flow speed should be between 0.5 to 1 meter per second. Flow speeds that are too fast or too slow can adversely affect the cooling efficiency of the heat sink, so the flow rate needs to be adjusted to an optimal level.

3. Supply Water Temperature: The supply water temperature should typically be between 15 to 30 degrees Celsius. Deviations in water temperature can impact the heat dissipation effectiveness of the liquid cooling plate.

4. Leakage Rate: The design of the liquid cold plate heat sink should minimize the risk of leakage or seepage. Therefore, considerations such as metal expansion, rubber sealing, and structural tightness are critical to ensure the plate's sealing integrity.

In summary, the design of custom liquid cold plate heat sinks must comprehensively consider heat dissipation, flow rate, material strength, and adhere strictly to standards to achieve the best cooling effect, ensuring stable performance and safe operation of electronic equipment.
