the high heat dissipation component just like power electronic devices usually use cold plate to control its hotspot temperature, water cooling plate is made of Cu or Al which has high heat conduction, as it works, implant water circulation system into the cold plate, and fasten electronic component on the cold plate, make use of the flowing water to take away the heat dissipated by the devices. compared with the air cooling system, the heat capacity of water is 4 times of the air, so water have better thermal load capacity, under situations of the same temperature rise and mass flow rate, the quantity of heat which water absorbent is also 4 times of the air.
