Knowledge misunderstanding of water-cooled plate


The concept of radiator and water cooling plate.

Radiator. Heat is generally exchanged through liquid circulation, called radiator, and many are also called heat exchangers, which means heat exchangers, such as finned radiators in cars; If it is directly in contact with electronic components and devices This kind of radiator is generally translated as cooler,   such as CPU cooler, computer radiator. At the same time, some people call the heat sink, heatsink, also called a radiator. Strictly speaking, the heat sink does not have a fan, it is just a hardware product. The air-cooled radiator is a combination of the heat sink and the fan. The radiator radiates the heat of the device directly to the outside world.

Water-cooling plate, called cold plate abroad, literally called cold plate, many domestic translations are water cooling plate, or liquid cooling plate. This is a kind of element that exchanges heat through liquid cooling, and the principle is to form a flow channel in the metal plate. The component is installed on the surface of the board (the middle is coated with a heat-conducting medium), and the cooling liquid enters from the inlet of the board and exits from the outlet to take away the heat emitted by the component. Common processes for forming water-cooled plate runners include friction welding, vacuum brazing, buried copper pipes, and deep hole drilling.

If the radiator is understood as a heat exchanger, then the radiator + water cooling plate + water pump + pipeline forms a complete liquid cooling system. The water-cooling plate is responsible for absorbing the heat of the heating element and transferring it to the flowing liquid, and the radiator is responsible for absorbing the heat from the added liquid with fins, and then through the heat exchange between the outside air and the fin surface, to achieve the purpose of cooling and cooling the components...
