The principle of Liquid Cold Plate is to form a flow channel in a metal plate, and the electronic components are installed on the surface of the water-cooled plate (with a heat-conducting medium in the middle). The internal coolant enters from the inlet and flows out from the outlet with the heat of the components. While water or water/glycol are the most common fluids used in liquid cooling, gasoline, oil, and refrigerant are other fluids that can be utilized.
