This change directly results in the possibility of the heat dissipation of the data center increasing from the original few kilowatts to hundreds of kilowatts, and the power density of the data center room continues to increase, which presents challenges to the heat dissipation system of the data center room. The traditional heat dissipation mode of the data center machine room is to achieve the purpose of cooling data center machine room equipment such as a server by reducing the temperature of the whole data center machine room, and the method is not only seriously wasteful in power, but also has very little effect, and cannot thoroughly solve the hot spot problem of the data center, and many data centers have the problems of too high cost of refrigeration equipment and running cost, too poor maintainability and expandability and the like. Therefore, the liquid cooling heat dissipation scheme is proposed by focusing the heat dissipation technology on the heat source inside the server. In recent years, liquid cooling heat dissipation schemes are widely applied, and the heat dissipation requirement of a large-scale data center is met to a certain extent, but a liquid cooling heat dissipation system needs to be tightly coupled with a rack and equipment, so that the pipeline layout, the rack design and the equipment wiring are relatively complex, the liquid cooling cabinet is large in volume and occupied area, and the maintenance is difficult.
