The water outlet pipeline 11 is used for high-temperature water outlet, and the water return pipeline 12 is used for providing low-temperature water return, so that high-temperature water for heat exchange in the condenser module 2 is pumped out, and low-temperature cooling water is input into the condenser module 2 for heat exchange.
The server module 3 includes a housing 31, a cooling liquid accommodating chamber 32 located in the housing 31, and a gasification chamber 33 located above the cooling liquid accommodating chamber 32. The housing cooling liquid storage chamber 32 and the vaporizing chamber 33 are sealed inside the housing, the housing further includes a top cover 311 covering the vaporizing chamber, and a seal ring 312 is provided inside the top cover 311. The cooling liquid accommodating cavity 32 has therein a cooling liquid 34 and server hardware 35 immersed in the cooling liquid 34, which is CPU multicore server hardware in this embodiment.
