The beneficial effects of the utility model are as follows: in the utility model, the water bath energy exchange is performed on the water cooling pipe through the hot water tank, and the design of the heat medium and the pipe of the hot tank can increase the contact area of the two, thereby obtaining a larger heat exchange effect, The heat medium enters the heat exchange chamber through the heat medium inlet pipe, and is discharged from the heat medium outlet pipe pipe. The heat medium flows through the baffle plate S-shaped to obtain a large energy exchange with the cold water inside the pipe, and the cold fluid obtained by heat exchange is stored in the storage. The thermal insulation buffer in the thermal cavity gets rid of the traditional single heat exchange form. The contact between the pipeline and the heat medium enables the energy exchange and the storage of the exchanged fluid, which saves costs and greatly improves the exchange efficiency.
