Through the configuration of the pipe group 1, when the water main unit 4 cools the coolant, its heat dissipation end will be connected to the water radiator 2 through the pipe group 1, and the water radiator 2 will discharge the heat to the outside of the cabinet 1. The configuration of the water cooling fan 3 can accelerate the heat dissipation.
