[0003] During the operation of the side-blowing outdoor unit, a variable frequency drive board is generally installed on the surface of the side-blowing outdoor unit. Since the side-blowing outdoor unit will generate more heat during use, the variable frequency drive board can reduce the overall operating power by adjusting the current connected to the inside of the side-blowing outdoor unit, thereby reducing heat and energy consumption.

[0037] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0038] A self-heating and dust filtering side-blowing outdoor unit, referring to Figure 1 , including an outer box body 1 and a frequency conversion drive board 11 arranged on one side of the outer box body 1 and a condensing fan blade 12 arranged on the other side of the outer box body 1. The airflow enters the interior of the outer box body 1 through one side of the outer box body 1 and is cooled by the frequency conversion drive board 11, and then the gas is discharged through the condensing fan blade 12, thereby achieving the effect of processing and discharging indoor gas.

[0039] Reference Figure 2-4 The inner side of the outer box body 1 is divided into a filter cavity 2 and a heat dissipation cavity 3, and the filter cavity 2 and the heat dissipation cavity 3 are separated by a partition 4. The heat dissipation cavity 3 is used to dissipate heat for the variable frequency drive board 11, and the filter cavity 2 is used to filter the air entering the filter cavity 2, and also filter and block the refluxed gas. The condensing fan blades 12 are placed in the filter cavity 2, and the variable frequency drive board 11 is placed in the heat dissipation cavity 3. A heat dissipation structure 31 is fixedly arranged in the heat dissipation cavity 3. The heat dissipation structure 31 includes a heat dissipation channel 311. The gas dissipates heat through the heat dissipation channel 311, thereby reducing the temperature of the variable frequency drive board 11. The heat dissipation channel 311 is connected to the filter cavity 2, and the flow of gas forms a flow cooling from the heat dissipation cavity 3 to the filter cavity 2.

[0040] Reference Figure 2-4 The heat dissipation structure 31 also includes a heat dissipation fan 312 arranged on one side of the heat dissipation channel 311. The heat dissipation fan 312 can introduce gas into the heat dissipation channel 311 by rotating. The heat dissipation fan 312 is connected to the heat dissipation channel 311. The outer side of the heat dissipation channel 311 is covered with a heat dissipation outer shell 313. The heat dissipation outer shell 313 is fixedly connected to the back of the variable frequency drive board 11, thereby achieving the function of fixing the heat dissipation pipeline on the back of the variable frequency drive board 11 and improving the heat dissipation capacity. The heat dissipation structure 31 also includes a heat dissipation fin 314 fixedly arranged on the inner wall of the heat dissipation channel 311. The heat dissipation fin 314 further improves the heat dissipation capacity in the heat dissipation channel 311.

[0041] Reference Figure 2-5A filter structure 21 is provided in the filter cavity 2. The filter structure 21 includes a filter plate 211. A plurality of filter holes 212 are provided on the surface of the filter plate 211. A sticky coating is applied between the filter gaps to adhere the dust. When the filter plate 211 and the surface of the partition plate 4 are attached, the filter holes 212 are connected to the heat dissipation channel 311. The filter holes 212 can ensure the passage of gas and ensure that the dust stagnates and adheres to the surface of the filter plate 211. The filter structure 21 also includes a filter cylinder 213 fixedly provided on the inner bottom wall of the outer box body 1. The output end of the filter cylinder 213 is fixedly connected to the bottom end of the filter plate 211. The filter cylinder 213 can push the filter plate 211 away from or close to The heat dissipation channel 311 is used for filtering when filtering is required, and can ensure the maximum gas ventilation effect when filtering is not required. A shock absorber 214 is provided on the side of the filter plate 211 away from the filtering cylinder 213, and a shock absorber groove 41 matching the shock absorber 214 is provided on the surface of the partition 4. When the filter plate 211 is attached to the surface of the partition 4, vibration will be generated when the outer box body 1 is working, and the dust stuck to the shock absorber 214 will be scattered by the working vibration. A shock absorber guide surface 215 is provided on the surface of the shock absorber 214, and the shock absorber 214 has elastic deformation performance. The shock absorber 214 is made of rubber material, which further improves the fitting degree and shock absorption strength of the shock absorber 214 and the shock absorber groove 41.

[0042] The implementation principle of the embodiment of the present application is as follows: when the device is started and cooling and filtering are required, the filter cylinder 213 is started so that the surfaces of the filter plate 211 and the partition plate 4 collide with each other, and the shock absorbing member 214 extends into the shock absorbing groove 41, and the heat dissipation fan 312 is started. The heat dissipation fan 312 allows the airflow to flow in through the heat dissipation channel 311 and be cooled by the heat sink 314. When passing through the outlet of the heat dissipation channel 311, dust will adhere to the surface of the filter plate 211, and the airflow will be blown out through the condensing fan blades 12. When filtering is not required, the filter cylinder 213 is adjusted so that the filter plate 211 is away from the heat dissipation channel 311, so as to increase the airflow rate in the heat dissipation channel 311 and improve the heat dissipation effect, thereby achieving the effect of heat dissipation of the variable frequency drive board 11 and filtering dust in the air.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
