[0031] Please see Figure 2The heat exchange box 2 includes a box body 11. An upper box cover 12 is installed on the top of the box body 11 by multiple screws, and a lower box cover 13 is installed on the bottom of the box body 11 by multiple screws. The motor 3 is installed on the lower box cover 13. A first water inlet pipe 14 is provided on the bottom side of the box body 11, and a first water outlet pipe 15 is connected to the top side of the box body 11. Sealing gaskets 16 are provided between the upper box cover 12 and the lower box cover 13 and the box body 11 to ensure the sealing of the connection between the upper box cover 12 and the lower box cover 13 and the box body 11.
