The water cooling plate 1 is provided with an inlet water branch 11 and an outlet water branch 12. The inlet water branch 11 and the outlet water branch 12 are respectively provided with an inlet 13 and an outlet 14. The water-air heat exchanger 2 and the fan 3 are located inside the closed box body 5.
[0021] The water-air heat exchanger 2 includes a plurality of flat tubes 22 inserted into the two side header pipes 21. Adjacent two flat tubes 22 are provided with a fin 23.
