[0002] With the development of information technology, the demand for information storage and transmission is increasing, and the power of servers is increasing accordingly. One of the problems caused by high power is the increase in heat generation. In order to ensure its operating efficiency, it is necessary to use cooling equipment to cool it down. Common cooling methods are air cooling, liquid cooling and immersion water cooling. Immersion water cooling is often used in high heat density environments such as data centers due to its high thermal conductivity. In the existing technology, the server is immersed in the coolant as a whole, and the heat is directly transferred to the coolant. The heat is dissipated through the circulation of the coolant or the evaporation and condensation phase change process. However, when the server is immersed in an open cabinet for heat dissipation, part of the boiling coolant cannot be recovered by the condenser and directly evaporated. When the target server is taken out of the cabinet for maintenance and inspection, part of the coolant will flow out of the cabinet, causing secondary waste, which is not conducive to the utilization of the coolant.
