It is an inlet or water outlet. When the first effluent port 41 and the second water port 51 are combined into an outlet, the first inlet port 31 and the second water outlet 61 are inlet, the refrigerant from the first inlet port 31 and the second water port 61 into, respective The refrigerant passage flowing through the cavity 8 is finally flowing out from the water cavity 8; when the first outlet 41 and the second water port 51 are combined into an inlet, the first water port 31 and the second water port 61 For the water outlet, the refrigerant is entered in the cavity 8, each flows through the refrigerant passage of the cells in which the cell is located, and flows out of the first inlet port 31 and the second water port 61, respectively.
