The upper end of the connection body 230 is hermetically connected to the gas inlet 210, and the lower end of the connection body 230 is hermetically connected to the gas flow passage 310. The hotter air in the accommodating space 110 enters the gas flow passage 310 through the air inlet 210 and the connection body 230, and the temperature of the air in the gas flow passage 310 is lowered due to the heat exchange of the cooling water.

The other end of the gas flow passage 310 passes out of the side of the water tank 300 to the outside of the cabinet 100 to be connected with the gas pipe 400 in a sealing manner, as shown in fig. 2, the gas pipe 400 extends upward to the top of the cabinet 100 and then passes into the diffusion space in the cabinet 100, and the gas pipe 400 forms a gas outlet 410 in the diffusion space. The air after heat exchange and temperature reduction walks upwards from the outside of the cabinet 100 to reach the top of the cabinet 100, and enters the diffusion space 130 through the air outlet 410 by the air pipe 400 bent into the cabinet 100.
