Liquid cold plate is a cooling device that uses liquid circulation to absorb and conduct heat. It is widely used in electronic equipment with high power density and high heat load. Compared with traditional air cooling systems, liquid cooling radiators have higher thermal conductivity and more uniform temperature control capabilities. They are an important means to achieve efficient heat dissipation in the fields of electronics, communications, computers and new energy. Liquid cold plate introduces cooling liquid (such as water, ethylene glycol solution, etc.). Liquid channels are arranged on the plate to enter the device. Driven by a liquid pump, the cooling liquid flows along the preset channel to absorb the heat generated by electronic components or heat sources. Subsequently, the liquid that takes away the heat is transported to an external radiator or heat exchanger, and the temperature is reduced by exchanging heat with the external environment, and then circulated back to the cold plate to form a complete thermal management system. Liquid cold plate Utilize the high heat capacity and thermal conductivity of liquid to quickly and efficiently transfer heat from the heat source to the cooling medium. Compared with air-cooled systems, liquid-cooled heat sinks have higher thermal conductivity and can handle heat sources with higher power density, avoiding performance degradation or damage to electronic equipment caused by overheating. Liquid-cooled systems form a uniform flow of coolant across the entire cold plate, ensuring a more uniform temperature distribution on the surface of the device and avoiding local overheating. This uniform temperature control is very important for electronic components that require precise temperature management, such as power semiconductors, lasers, etc. Liquid-cooled heat sink systems are generally quieter than air-cooled systems because they do not require high-speed fans for forced convection heat dissipation. This is particularly beneficial for application scenarios that require a quiet working environment, such as data centers, laboratory equipment, and high-performance computers.
