Basic info of a liquid cooling system

A hydraulic circuit called the liquid cooling system is composed of a cold plate, a pump, and a heat exchanger. The cold plate is responsible for absorbing the heat from the source, while the pump circulates the fluid throughout the system. The heat exchanger then removes the absorbed heat from the liquid.

Cold plates can be simple or complex, using different technologies to achieve optimal heat transfer. These technologies may include high heat transfer fins, micro or meso channels, or varied manufacturing processes like vacuum, CAB, or dip brazing.

When choosing the cold plate and liquid system components, it's important to consider allowable pressure drop, flow rate, and material compatibility. The pump's force and flow rate determine the allowable pressure drop. Compatibility of materials and fluids throughout the system is crucial to prevent galvanic corrosion and optimize the system for the intended application.
