Referring to fig. 1 and 3 to 6, an embodiment of the present invention provides an outdoor unit 100 of an air conditioner, including: a housing 200 having a mounting cavity 250 formed therein; a center spacer 240 installed in the housing 200, the center spacer 240 dividing the installation cavity 250 into a blower cavity 251 and a press cavity 252; the electric control box 300 is installed on the middle partition plate 240, a heat dissipation air duct 320 is formed inside the electric control box 300, two ends of the heat dissipation air duct 320 are provided with a first air opening 321 and a second air opening 322 which are mutually communicated, the first air opening 321 is communicated with the fan cavity 251, the second air opening 322 is communicated with the press cavity 252, and in the vertical direction, the first air opening 321 is positioned below the second air opening 322; the heat dissipation module 400 is installed in the heat dissipation air duct 320.

It should be noted that the fan cavity 251 of the outdoor unit 100 of the present application is further provided with components such as a wind wheel 260, a driving motor (not shown in the drawings), and a motor bracket 270, wherein the motor bracket 270 is fixed on the casing 200, the driving motor is installed on the motor bracket 270, the driving motor is connected to the wind wheel 260 and is used for driving the wind wheel 260 to rotate, and when the wind wheel 260 rotates, the driving motor drives the airflow in the fan cavity 251 to rapidly flow. The compressor 280 and other components are installed in the compressor chamber 252 of the outdoor unit 100.

The electric control box 300 is vertically installed on the middle partition 240, so that the space utilization rate in the casing 200 can be improved, and the volume of the outdoor unit 100 of the air conditioner can be reduced; and the heat dissipation air duct 320 connecting the fan cavity 251 and the press cavity 252 is disposed inside the electronic control box 300, when the air conditioner outdoor unit 100 operates, negative pressure is generated in the fan cavity 251, and then the air flow in the press cavity 252 is driven to enter the heat dissipation air duct 320 through the second air opening 322 and flow into the fan cavity 251 through the first air opening 321, and further the air flow is driven to rapidly pass through the heat dissipation module 400, so as to rapidly cool the electronic control box 300. In addition, since the first air opening 321 is located at the lower side of the second air opening 322 in the vertical direction, the air flow forms a "chimney effect" in the heat dissipation air duct 320, which increases the air flow entering the heat dissipation air duct 320 and increases the air flow speed, thereby further improving the heat dissipation efficiency of the electronic control box 300.

Specifically, the first tuyere 321 is disposed near the middle of the middle partition 240, and/or the second tuyere 322 is disposed near the top end of the middle partition 240.

It will be appreciated that the rotor 260 rotates with its edge nearest the middle of the center spacer 240.

That is, the first air opening 321 is disposed as close to the wind wheel 260 as possible, when the wind wheel 260 rotates, the negative pressure at the first air opening 321 may be increased to further increase the air flow rate and the air flow speed entering the heat dissipation air duct 320. And the second air opening 322 is arranged close to the top end of the middle partition 240, so that the height difference between the first air opening 321 and the second air duct can be prolonged, and the chimney effect of the heat dissipation air duct 320 is improved, so as to improve the heat dissipation efficiency of the electronic control box 300.

Specifically, the heat dissipation module 400 is composed of a plurality of heat dissipation fins 410.

In some embodiments, the heat dissipation duct 320 is an L-shaped duct.

It should be noted that, the outdoor unit 100 is installed at the outdoor side, but the outdoor environment is variable, when the outdoor air contains a large amount of moisture, a part of the moisture enters the heat dissipation air duct 320, and condensed water is easily formed on the inner side wall of the heat dissipation air duct 320 and the inner side wall of the pressing cavity 252, which may cause a risk of electric leakage.

The interior of the L-shaped heat dissipation air duct 320 is only turned once, and the structure is simple; and because the first air opening 321 is located at the lower side of the second air opening 322 in the vertical direction, the first air opening 321 vertically extends upwards to form a section of heat dissipation air duct 320, so that the condensed water can enter the press cavity 252 only by doing work in the vertical direction, the probability that the condensed water enters the press cavity 252 is reduced, and the safety of the outdoor air conditioning unit 100 is improved.

Further, in other embodiments, the heat dissipation air duct 320 may also be a Z-shaped air duct, a U-shaped air duct, or the like, which is not limited herein.

In some embodiments, a water blocking rib 330 is disposed at an end of the heat dissipating air duct 320 close to the second air opening 322.

When the humidity in the outdoor air is high, the water blocking ribs 330 are disposed in the heat dissipation air duct 320, so that condensed water condensed on the inner side wall of the heat dissipation air duct 320 can be blocked, the condensed water can be prevented from flowing into the compressor cavity 252, and the safety of the outdoor unit 100 of the air conditioner is improved. And the water blocking ribs 330 are arranged close to the second air port 322, so that more condensed water can be prevented from entering the press cavity 252 as much as possible.

Illustratively, when the heat dissipation air duct 320 is an L-shaped air duct, the water blocking ribs 330 are disposed at the turning positions of the heat dissipation air duct 320.

In some embodiments, the electrical control box 300 includes a box body 310 and a PCB 500, the heat dissipating duct 320 is formed in the box body 310, an opening 340 is formed at one side of the box body 310 located in the press cavity 252, and the PCB 500 is installed in the opening 340.

Usually, the condensate water can vertically drip, because the box body 310 is vertically installed on the median septum 240, most of the condensate water can be stopped at the top of the box body 310, and the condensate water can not flow into the left and right sides of the box body 310, so that the design of the opening 340 can be made on one side of the box body 310. On one hand, the structure of the box body 310 is simplified, on the other hand, the air circulation speed on the surface of the PCB 500 is increased, and the heat dissipation efficiency of the electric control box 300 is improved.

Referring to fig. 1 and 6, in some embodiments, an included angle between a plane of the PCB 500 and a plane of the middle partition 240 is an acute angle.

It should be noted that, the outdoor unit 100 is installed at the outdoor side, and there are many impurities and dusts in the outdoor environment, and after the outdoor unit 100 runs for a long time, there may be many impurities deposited on the PCB 500 in the opening 340.

Through setting up PCB board 500 slope, most subsides the impurity on PCB board 500 and can continue the landing under self action of gravity, and it has effectively avoided piling up of impurity on PCB board 500.

Preferably, referring to fig. 6, indicated at K, an included angle between a plane of the PCB 500 and a plane of the middle spacer 240 is 3 °.

Further, in other embodiments, the included angle between the plane of the PCB 500 and the plane of the middle partition 240 may also be 2 °, or 5 °, and the like, which is not limited herein.

In some embodiments, the electronic control box 300 further comprises a dust guard 600, and the dust guard 600 is mounted on the top of the box body 310.

By providing the dust guard 600 at the top of the case 310, the probability of impurities settling on the PCB 500 may be reduced.

In some embodiments, the top of the electrical control box 300 is provided with a waterproof sponge (not shown).

It should be noted that the waterproof sponge has small internal gaps, which can effectively block the flow of internal water.

By installing the waterproof sponge on the top of the electric control box 300, the probability of the condensed water flowing into the fan cavity 251 can be reduced.

Referring to fig. 2 to 6, in some embodiments, the housing 200 is formed by a bottom plate 220, a top plate (not shown), a side plate 230, a front plate and a heat exchanger 210; the included angle between the plane of the middle partition plate 240 and the plane of the heat exchanger 210 is B, wherein B satisfies the following condition: b is more than 60 degrees and less than 90 degrees.

The housing 200 is in a rectangular parallelepiped shape, and the middle partition 240 is obliquely arranged, so that compared with the common middle partition 240 perpendicular to the heat exchanger 210 in the prior art, the surface area of the middle partition 240 can be increased under the same volume condition of the housing 200, and further, the mounting housing usable area of the electronic control box 300 is increased, so that the electronic control box 300 can be provided with a larger heat dissipation air duct 320 and a heat dissipation module 400, and the heat dissipation efficiency of the electronic control box 300 is improved.

In addition, the electrical control box 300 mounted on the inclined middle partition 240 is also arranged in an inclined manner, so that more signals and/or power interfaces and the like on the surface of the electrical control box 300 can be exposed, which is convenient for technicians to assemble and improves the assembly efficiency of the outdoor unit 100 of the air conditioner.

In some embodiments, the middle partition 240 is spaced apart from the top plate.

In the transportation or installation process of the outdoor unit 100, the surface of the top plate may be deformed due to the influence of load, etc.; by arranging the gap between the middle partition 240 and the top plate, a safe concave deformation space can be left for the top plate, so that pressure is prevented from being completely transmitted to the middle partition 240, the compression deformation of the middle partition 240 is effectively avoided, and the structural stability of the outdoor unit 100 of the air conditioner is improved.

Specifically, the distance between the middle partition 240 and the top plate ranges from 2mm to 5mm.

In some embodiments, the electronic control pod 300 is removably coupled to the midplate 240.

It can improve the efficiency of assembling and disassembling the electric control box 300, and improve the efficiency of assembling the outdoor unit 100 of the air conditioner.

Specifically, the intermediate partition 240 and the electronic control box 300 can be installed in a buckle structure, that is, the electronic control box 300 can be vertically assembled downwards along the extending direction of the intermediate partition 240, and can be fixed on the intermediate partition 240 by utilizing the gravity of the electronic control box 300, so that the shaking of the electronic control box 300 is avoided, and the installation efficiency of the electronic control box 300 is improved.

Further, in other embodiments, the electrical control box 300 and the middle partition 240 may be mounted by a snap fit, a screw connection, or the like, and are not limited herein.

Further, the distance range from the top end of the middle partition 240 to the electric control box 300 meets 2 mm-5 mm.

The distance between the electric control box 300 and the middle partition 240 from the top plate is further increased, the electric control box 300 is prevented from being directly contacted when the top plate is sunken and deformed, the extrusion damage of the electric control box 300 is effectively avoided, and the operation safety of the electric control box 300 is guaranteed.
