Data center liquid cooling mainly has three deployment methods: cold plate, immersion, and spray. Cold plate liquid cooling is an indirect liquid cooling method, while immersion and spray are direct liquid cooling methods. In the cold plate liquid cooling system, heat-generating components do not come into direct contact with the liquid but transfer heat through cold plates filled with liquid (usually enclosed cavities made of conductive metals such as copper or aluminum), and then the liquid circulation carries away the heat. Since server chips and other heat-generating components do not need to come into direct contact with the liquid, the system does not require a complete redesign of the entire data center equipment, making it more operable. Therefore, cold plate liquid cooling is also the most mature and widely used of the two liquid cooling methods.

Fluid Connector

Cold plate liquid cooling servers utilize fluid connectors. A fluid connector is a type of joint that can establish or disconnect fluid pathways without the need for tools, preventing liquid leakage and supporting hot swapping of pipelines, ensuring that no coolant leaks during system installation or maintenance. Fluid connectors are selected based on different flow rates with varying diameter specifications; different materials are chosen based on fluid parameters; self-locking and blind mating forms are selected according to the system's locking method; and specific products are custom-developed based on special product requirements, etc.
