The rear end of the second plate portion 312 is provided with a second positioning protrusion and a third threaded hole. The front end of the third plate portion 313 is provided with a fourth threaded hole and a second positioning hole, the fourth threaded hole being aligned with the third threaded hole, and the second positioning protrusion being inserted into the second positioning hole. The rear end of the third plate portion 313 is fixedly connected to the frame 10.

[0060] In this embodiment, the tube sheet 310 includes a first plate portion 311, a second plate portion 312, and a third plate portion 313 arranged sequentially. The shape and area of ​​the tube sheet 310 need to be adapted to the evaporator 30, which makes the shape of the tube sheet 310 relatively complex. Therefore, it is not convenient to place during transportation and there is a risk of bending or damage. Setting the tube sheet 310 into multiple plate portions makes it easier to place during transportation and reduces the risk of bending or damage to the tube sheet 310.

[0061] Furthermore, the first locking hole 320 is provided on the second plate portion 312, and the second locking hole 340 is provided on the flange 330 of the second plate portion 312. The third plate portion 313 is located on the rear side of the motor cover 40.
