This design is particularly suitable for the ends of the conveyor line 1.

[0058] In one embodiment, if Figure 4As shown, the second end 37 of the cooling device 3 is provided with a hollow air outlet shell 31, the inner cavity of the air outlet shell 31 is connected to the first end 36 of the cooling device 3, and a first air outlet 311 is provided on the side of the air outlet shell 31 close to the operating space.

[0079] Specifically, by setting up a heat exhaust condenser 223 between the heating condenser 222 and the evaporator 221, the refrigerant that has not been fully heat exchanged in the heating condenser 222 can be more fully heat exchanged in the heat exhaust condenser 223, and then the refrigerant can also be fully heat exchanged in the evaporator 221, so that the temperature of the air after heat exchange with the evaporator 221 is lower, and the cooling of other specific locations is achieved more effectively.
