Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly relates to an outdoor unit of an air conditioner. Background Art

[0002] In the existing outdoor unit of an air conditioner, there is a middle partition board which separates the fan and the compressor of the outdoor unit of the air conditioner. The electrical box is arranged on the middle partition board on the side of the compressor. The heat generated by the electronic components in the electrical box during use can only be conducted to the side of the compressor. However, the side of the compressor is a closed space and there is no air flow inside, so the heat dissipation effect is poor. In this regard, the prior art (CN111878912A) discloses a heat dissipation assembly, an outdoor unit and an air conditioner for an outdoor unit of an air conditioner. The heat dissipation assembly of the air conditioner includes a compressor cavity. An air inlet hole is arranged on the middle partition board, and air enters the compressor cavity through the air inlet hole. An air outlet hole is arranged on the middle partition board, so that after the external air of the outdoor unit flows into the compressor cavity, it then flows out through the air outlet hole, thereby reducing the temperature in the compressor cavity. Both the air inlet hole and the air outlet hole are relatively small, and the heat dissipation is uneven. Therefore, there are certain limitations in this kind of heat dissipation assembly, outdoor unit and air conditioner for an outdoor unit of an air conditioner. Therefore, it is necessary to provide an outdoor unit of an air conditioner to solve the above problems. Summary of the Utility Model

This figure is a simplified schematic diagram, which only illustrates the basics of the present utility model in a schematic manner, so it only shows the components related to the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the protection scope of the present utility model.

[0023] Please refer to Figure 1 、 2 As shown in the figure, the present utility model provides an outdoor unit 1 of an air conditioner, which includes a housing 10, a middle partition board 20 arranged inside the housing 10, a compressor chamber 30 on one side of the middle partition board 20, and a fan chamber 40 on the other side of the middle partition board 20.

[0024] The housing 10 is a shell-like structure surrounded by a panel 11, a heat exchanger 12, a side plate 13 and a bottom plate 14. The panel 11, the heat exchanger 12 and the side plate 13 are fixedly connected by screws.

[0025] The panel 11 is a cover plate-like structure with both ends bent, and the heat exchanger 12 and the side plate 13 are respectively connected to both ends. The panel 11 is provided with a first air outlet 111 on one side of the fan chamber 40.

[0026] The heat exchanger 12 is generally in an "L"-shaped sandwich structure. One side of the heat exchanger 12 is arranged directly opposite to the panel 11, and the other side of the heat exchanger 12 is arranged directly opposite to the side plate 13. One end of the heat exchanger 12 is connected to the panel 11, and the other end of the heat exchanger 12 is connected to the side plate 13.

[0027] A handheld part 131 is formed by inwards recessing on the outer surface of the side plate 13. The top of the handheld part 131 is recessed inwards, and the lower end of the handheld part 131 is flush with the side plate 13. By applying an upward force to the handheld part 131, the outdoor unit 1 of the air conditioner can be lifted. A fixing part 132 is also provided on the outer surface of the side plate 13, and a first wire passing hole 1321 and a second wire passing hole 1322 are also provided on the fixing part 132.

[0028] Please refer to Figure 3 、 4 As shown in FIGS. 5, the middle partition plate 20 is generally in an "L"-shaped plate structure. The front end of the middle partition plate 20 is connected to the front panel 11, the rear end of the middle partition plate 20 is connected to the heat exchanger 12, the bottom of the middle partition plate 20 is connected to the bottom plate 14. On the vertical surface of the middle partition plate 20 facing the side plate 13, a variable frequency control board 21 is provided, and electrical components 211 are provided on the variable frequency control board 21. The long strip-shaped gap between the middle partition plate 20 and the front panel 11 is the second air outlet 22, and an air inlet 23 is provided at the upper end of the vertical surface of the middle partition plate 20 facing the front panel 11.

[0029] On the side surface of the middle partition plate 20 facing the front panel, a first abutting protrusion 221 and a second abutting protrusion 222 are provided, and the second air outlet 22 is provided between the first abutting protrusion 221 and the second abutting protrusion 222.

[0030] The air inlet 23 is in the shape of louver holes, and a brim 231 is provided at the top of the air inlet 23.

[0031] A compressor 31 is provided in the compressor chamber 30. The air flow enters the compressor chamber 30 through the air inlet 23. The air flow takes away most of the heat through the electrical components 211 on the variable frequency control board 21, and then flows out of the compressor chamber 30 through the second air outlet 22.

[0032] A blower 41 is provided in the center of the blower chamber 40. The blades of the blower 41 face the first air outlet 111, and the air flow flows out of the air conditioner outdoor unit 1 through the first air outlet 111.

[0033] The working process of the air conditioner outdoor unit 1 of the present invention will be described below in conjunction with the accompanying drawings:

[0034] When the blower 41 rotates, the air flow is discharged from the blower chamber 40 through the first air outlet 111. Thus, a negative pressure is generated in the blower chamber 40, and the air flow enters the compressor chamber 30 through the air inlet 23 on the middle partition plate 20, and then passes through the electrical components 211 on the variable frequency control board 21. The heat generated by the electrical components 211 is taken away by the air flow. Under the action of the negative pressure in the blower chamber 40, the heat flows through the second air outlet 22 and then through the first air outlet 111 and is discharged from the air conditioner outdoor unit 1.

[0035] Therefore, the air conditioner outdoor unit 1 of the present invention has at least the following beneficial effects:

[0036] The air flow enters from the bottom of the air inlet 23. After the air flow at the air inlet 23 is inhaled, it flows through the surface of the variable frequency control board 21, taking away part of the heat on the heat-generating electrical components 211, with uniform heat dissipation and accelerated heat dissipation.

[0037] The air inlet 23 is surrounded by a complete circle of brim 231. The brim 231 at the top of the air inlet 23 effectively prevents rainwater from dripping in, avoiding the risk of rainwater eroding the electrical components 211.
