DETAILED DESCRIPTION

[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

This solution completely realizes the mutual isolation of the water circuit module 400 and the electric control module 200, so that when the water circuit module 400 leaks, the leaked water will be blocked by the fluorine circuit module 300 and will not splash upward onto the electric control module 200, so the electric control module 200 is less likely to be damaged by water.

[0036] Among them, Figures 1 to 7 As shown, the heat exchange chamber 110 is located on the left side of the installation chamber 120, and the heat exchange chamber 110 and the installation chamber 120 are separated by a partition 130.

The compressor 340 is close to the front side plate of the right front side plate, and the water circuit module 400 is located on the lower side of the water receiving pan 330. In this solution, the length of the refrigerant pipeline between the compressor 340 and the heat exchanger is slightly different from the length of the refrigerant pipeline between the compressor 340 and the water fluorine plate exchanger 410, which can reduce the pressure loss in the refrigerant pipeline and improve the heat exchange effect of the fluorine circuit module 300.

[0049] Among them, Figure 3 and Figure 4 As shown, the rear portion of the water receiving tray 330 is fixed to the top of the second mounting frame 520, and the front end of the water receiving tray 330 is fixed to the chassis of the shell 100 through one or more support beams 530 (the multiple support beams 530 can be two support beams 530 spaced apart from each other on the left and right, three support beams 530 spaced apart from each other on the left and right, or four support beams 530 spaced apart from each other on the left and right, etc.), and the left end of the water receiving tray 330 is fixed to the partition 130.
