Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example 1:

as shown in fig. 1 to 5, the outdoor unit electrical box of an air conditioner of the present embodiment relates to an axial fan and a right side plate handle, and includes a box body 2, a controller 22 and a controller carrier 23 are sequentially installed in the box body 2 from top to bottom, a partition board is disposed in the middle of the controller carrier 23, and two sides of the partition board are open structures and are used for carrying electronic components on the controller 22; the IPM221, the diode 222, the IGBT223 and the rectifier bridge 224 are carried on the left side of the partition board, the electrolytic capacitor 225 is carried on the right side of the partition board, and a radiator is fixed on the lower portion of the electronic component carried on the left side of the partition board; the partition board is provided with a vent 232, the heat dissipation channels of the heat dissipation fins of the heat dissipater 24 face the vent 232, and a heat dissipation air duct is formed between the heat dissipater 24 and the controller 22 at the left and right ends of the box body 2, and between the axial flow fan and the handle of the right side plate.

Since the IPM221, the diode 222, the IGBT223, the rectifier bridge 224, and the electrolytic capacitor 225 of the present embodiment generate much heat during operation, the heat sink 24 is provided below the electronic component, thereby increasing heat dissipation.
