According to the sixth concept of the present application, since the connection of the electrical box is improved, the electrical box is connected to the heat exchanger and the supporting part; the middle partition plate is not arranged in the shell, the electric box is sealed in the compressor bin, the electric box is connected and fixed through the middle partition plate, the whole compressor bin is sealed by the middle partition plate and the shell due to the fact that the electric box needs to be waterproof, and if the U-shaped heat exchanger is adopted at the moment, the heat exchange effect of the part of the heat exchanger opposite to the compressor bin is poor, the electric box needs to be waterproof, and therefore only the L-shaped heat exchanger can be adopted; therefore, the electric box is connected among the heat exchanger, the compressor and the supporting part by the heat exchanger and the supporting part formed by connecting a plurality of rod pieces or plate pieces, and meanwhile, the U-shaped heat exchanger is adopted, so that the unit rated capacity of the outdoor unit of the air conditioner can be improved, and the heat exchange effect of the heat exchanger is not influenced.

According to the seventh concept of the present application, since the electrical box is improved, the electrical box is set to be in a sealed form, and the first, second, and third limit installation parts, which fix the electrical box between the heat exchanger, the compressor, and the supporting part, are all welded to the electrical box, so that there is no need to punch or otherwise operate the outer surface of the electrical box, and the waterproof performance of the electrical box is ensured.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
