Principle Of Liquid Cold Plate Heat Sink

The liquid cold plate heat sink (water-cooled heat sink) takes away a large amount of heat through the friction of the liquid flow and the internal surface of the radiator to dissipate heat. Compared with general air-cooled heat sinks, liquid cold plate heat sinks have the advantages of quietness, stable cooling, and less dependence on the environment.

The heat dissipation performance of a liquid cold plate heat sink is directly proportional to the flow rate of the heat dissipation fluid (water or other liquid), and the flow rate of the refrigerant fluid is related to the power of the water pump in the refrigeration system. Moreover, the heat capacity of water is large, which makes the water-cooled refrigeration system have a good heat load capacity.

Principle of liquid cold plate heat sink

a complete liquid cold plate heat sink system is generally composed of a Water Cooling Plate, a circulating liquid water pump pipe, and a heat exchanger (water tank). Each part has its own unique function, such as a liquid-cooled plate radiator. The aluminum or copper-aluminum composite has a water channel radiator inside, and the circulating liquid. The liquid circulates in the pipeline through the action of the water pump. When the liquid absorbs the heat of the device, it will flow away from the water block on the device. The new low-oscillation circulating fluid continues to absorb the heat of the device.
