Referring to fig. 5 to 7, a heat dissipation fan 16 is disposed in the press cabin 2. The heat dissipation fan 16 is used for providing wind power in the press cabin 2, so that air in the press cabin 2 flows, and the flowing air can take away heat on the compressor 14 and the condenser 15, so as to dissipate heat of the compressor 14 and the condenser 15.

Referring to fig. 7, the heat dissipation fan 16 partitions the space inside the press cabin 2 into an air inlet space 201 and an air outlet space 202, wherein the air inlet space 201 is located on the air suction side of the heat dissipation fan 16, and the air outlet space 202 is located on the air outlet side of the heat dissipation fan 16. Therefore, when the heat dissipation fan 16 operates, the wind generated by the heat dissipation fan 16 enables the air in the air inlet space 201 to enter the air outlet space 202 through the heat dissipation fan 16.
