Because the current server mainly radiates heat in the air cooling mode, the radiating efficiency is relatively limited. In addition, manufacturers have developed a water-cooling heat dissipation method, which is a relatively more efficient heat dissipation method, and is also becoming common in the PC field. Therefore, many PCs with high heat dissipation requirements adopt a water cooling device to promote heat dissipation, but the water cooling heat dissipation is not widely applied in the field of server rooms, which is a serious disadvantage.

Because the water cooling device on the PC needs to comprise a set of liquid circulation system, the circulating power is output by the water pump, so that the low-temperature liquid flows through the CPU, the GPU and other high-heat-generating components and then returns to the water tank for cooling. The above steps are repeated to continuously dissipate heat. But because the PC is a stand-alone device. One water cooling device only needs to meet the heat dissipation requirement of one single PC. In a large server room, a plurality of server hosts are deployed in each cabinet, and are managed and maintained in a unified manner. In this case, it is obviously impractical to provide a separate water cooling device for each server host, making it difficult to perform maintenance one by one.
