Specific embodiments

[0024] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and the features in the embodiments in this application can be combined with each other arbitrarily.

[0025] Such as Figures 1 to 6As shown in the figure, the outdoor unit of the air conditioner provided by the embodiment of the present utility model includes: a housing 100; a middle partition 200 having a first opening 210 and a second opening 220 on the side, the middle partition 200 divides the interior of the housing 100 into a heat exchange chamber 110 and an installation chamber 120, and the heat exchange chamber 110 and the installation chamber 120 are arranged in sequence in the horizontal direction; an electric control assembly, the electric control assembly is provided at the first opening 210 and includes a radiator 310 and an electric control board 320, the radiator 310 is located on one side of the electric control board 320 and faces the heat exchange chamber 110, and an electric control element 321 is provided on the other side of the electric control board 320, and the electric control element 321 faces the installation chamber 120; and a first air guide cover 400 having a first air outlet 410 and a second air outlet 420, the first air guide cover 400 is located in the installation chamber 120 and is provided at the second opening 220, the first air outlet 410 faces the electric control element 321, and the second air outlet 420 is connected to the heat exchange chamber 110 through the second opening 220.

[0026] For this outdoor unit of the air conditioner, the first air outlet 410 faces the electric control element 321, and the second air outlet 420 is connected to the heat exchange chamber 110 through the second opening 220. In this way, the air flow passing through the first air outlet 410, the first air guide cover 400, the second air outlet 420 and the second opening 220 will flow through the electric control element 321 more, so the heat dissipation effect of the electric control element 321 is better.

[0027] It can be, as Figure 2 shown by the arrow in the figure, under the action of negative pressure suction, the air at the electric control element 321 in the installation chamber 120 enters the heat exchange chamber 110 in sequence through the first air outlet 410, the first air guide cover 400, the second air outlet 420 and the second opening 220; or it can be that under the action of positive pressure blowing, the air in the heat exchange chamber 110 blows towards the electric control element 321 through the second opening 220, the second air outlet 420, the first air guide cover 400 and the first air outlet 410; the above can all achieve the purpose of this application, and its gist does not deviate from the design idea of the present utility model, so it will not be elaborated here and all should fall within the protection scope of this application.

[0028] In some examples, as Figure 1 and Figure 2 shown in the figure, the outdoor unit of the air conditioner further includes: a second air guide cover 500 having a third air outlet 510 and a fourth air outlet 520, the second air guide cover 500 is located in the heat exchange chamber 110 and is provided at the second opening 220, the second air outlet 420 is connected to the third air outlet 510 through the second opening 220, and the fourth air outlet 520 faces the radiator 310. In this way, the air flow passing through the first air outlet 410, the first air guide cover 400, the second air outlet 420, the second opening 220, the third air outlet 510, the second air guide cover 500 and the fourth air outlet 520 will flow through the radiator 310 more, so the heat dissipation effect of the radiator 310 on the electric control board 320 is better.

[0029] In some embodiments, as Figure 2 shown, a water baffle wall 530 is provided inside the second air guide cover 500. The water baffle wall 530 is located between the third air outlet 510 and the fourth air outlet 520. One end of the water baffle wall 530 is located inside the fourth air outlet 520 and is connected to the middle partition plate 200 between the first opening 210 and the second opening 220. On the side of the water baffle wall 530 in the second air guide cover 500 facing away from the third air outlet 510, a water baffle air duct 540 is formed, and on the side of the water baffle wall 530 in the second air guide cover 500 facing the third air outlet 510, a flow-through air duct 550 is formed. The fourth air outlet 520, the water baffle air duct 540, the flow-through air duct 550, and the third air outlet 510 are connected in sequence (that is, the end of the water baffle air duct 540 away from the fourth air outlet 520 is connected to the flow-through air duct 550). Among them, the water baffle air duct 540 and the flow-through air duct 550 form a labyrinth-like bent passage between the fourth air outlet 520 and the third air outlet 510, so that water is less likely to reach the third air outlet 510 from the fourth air outlet 520 through the water baffle air duct 540 and the flow-through air duct 550 in sequence and drip onto the electronic control board 320. Therefore, the waterproof performance of the electronic control board 320 is better. Preferably, as Figure 2 shown, the water baffle wall 530 is a bent structure.

[0030] In some embodiments, as Figure 1 shown, the outdoor unit of the air conditioner further includes: a fan assembly. The fan assembly is arranged in the heat exchange chamber 110, and the radiator 310 is arranged adjacent to the wind wheel 600 of the fan assembly, so that the heat dissipation effect of the wind wheel 600 on the radiator 310 is better.

[0031] Preferably, the distance between the radiator 310 and the wind wheel 600 is set to be not greater than 80 mm. It can be that the distance between the radiator 310 and the wind wheel 600 is set to 30 mm; or it can be that the distance between the radiator 310 and the wind wheel 600 is set to 50 mm; or it can be that the distance between the radiator 310 and the wind wheel 600 is set to 80 mm, etc.; the above can all achieve the purpose of the present application, and its gist does not deviate from the design idea of the present invention, so it will not be elaborated here and all should fall within the protection scope of the present application.

[0032] In some embodiments, as Figure 1 shown, the outdoor unit of the air conditioner further includes: a heat exchanger 700. The heat exchanger 700 is arranged in the heat exchange chamber 110 and is located behind the wind wheel 600. A negative pressure area is formed between the heat exchanger 700 and the wind wheel 600. The radiator 310 and the fourth air outlet 520 are both located in the negative pressure area.

[0033] As Figure 2As shown, when the fan assembly operates, the air in the negative pressure area is blown forward through the wind wheel 600. Under the negative pressure suction of the negative pressure area, the air at the electronic control component 321 in the installation cavity 120 flows through the first air outlet 410, the first air guide cover 400, the second air outlet 420, the second opening 220, the third air outlet 510, the second air guide cover 500, and the fourth air outlet 520 to the radiator 310 in sequence. This solution not only provides better heat dissipation for the electronic control component 321, but also better heat dissipation for the electronic control board 320 by the radiator 310.

[0034] In some embodiments, as Figure 5 shown, the second opening 220 is located above the first opening 210, and the top of the radiator 310 is located within the fourth air outlet 520. As Figure 5 and Figure 6 shown, an air passing groove penetrating up and down is provided on the side of the radiator 310 facing away from the electronic control board 320. Thus, under the negative pressure suction of the negative pressure area, the air beam for dissipating heat from the radiator 310 blown out from the fourth air outlet 520 will flow along the air passing groove, which is beneficial to improving the heat dissipation effect of the air beam on the radiator 310.

[0035] In some embodiments, the first air guide cover 400 is a plastic part, and the plastic part has a good anti-condensation effect, which can prevent condensation on the surface (which can be the inner surface and the outer surface) of the first air guide cover 400. Or it can be that the first air guide cover 400 is a metal part, and an anti-condensation structure is provided on the surface (which can be the inner surface and the outer surface) of the metal part. The anti-condensation structure can prevent condensation on the surface of the first air guide cover 400. It can be that the anti-condensation structure is set as flannelette or sponge, etc., and all can achieve the purpose of this application. Its gist does not deviate from the design concept of the present utility model, and will not be elaborated here, and all should fall within the protection scope of this application.

[0036] Of course, it can also be that the first air guide cover 400 is a plastic part, and an anti-condensation structure is also provided on the surface of the plastic part. The anti-condensation structure is set as flannelette or sponge, etc., and can also achieve the purpose of this application. Its gist does not deviate from the design concept of the present utility model, and will not be elaborated here, and should also fall within the protection scope of this application.

[0037] In some embodiments, as Figure 2 、 Figure 4 shown, the outdoor unit of the air conditioner further includes: an installation frame 800, the electronic control assembly is arranged on the installation frame 800, and the installation frame 800 is arranged on the middle partition 200, that is, after the electronic control assembly and the installation frame 800 are assembled into a combined structure, the combined structure is then arranged on the middle partition 200. This solution can reduce the installation difficulty of the electronic control assembly and the installation frame 800 on the middle partition 200.

[0038] In one embodiment, as Figure 2 、 Figures 4 to 6As shown, the radiator 310 is installed on one side of the mounting frame 800. The electronic control board 320 is located on the other side of the mounting frame 800 and abuts against the radiator 310. Then, the electronic control board 320 is fixed to the radiator 310 by screws, so that the mounting frame 800, the radiator 310, and the electronic control board 320 are assembled into a combined structure. Then, the combined structure is placed in the installation cavity 120 and fixed to the middle partition 200. Among them, one end of the radiator 310 away from the electronic control board 320 passes through the first opening 210 and extends into the heat exchange cavity 110.

[0039] In one embodiment, as Figure 2 、 Figures 4 to 6 shown, the side surface of the mounting frame 800 is provided with a third opening 810 and a fourth opening 820. The third opening 810 is located below the fourth opening 820. The radiator 310 is fixed at the third opening 810 and closes the third opening 810. The second opening 220 and the fourth opening 820 are opposite to each other. The first air guide cover 400 is in the installation cavity 120 and is arranged at the fourth opening 820. The second air guide cover 500 is in the heat exchange cavity 110 and is arranged at the second opening 220. Among them, a hook 821 (i.e., the hook 821 is the second hanging part) is provided on the lower wall of the lower opening of the fourth opening 820, and the hook 821 is hooked on the lower wall of the lower opening of the second opening 220. The lower end of the mounting frame 800 is provided with a first folded edge 830 (the first folded edge 830 is the first hanging part) bent toward the side where the heat exchange cavity 110 is located, and the first folded edge 830 is hung on the lower wall of the lower opening of the first opening 210. In this scheme, the assembly method of the mounting frame 800 and the middle partition 200 is simple and convenient, realizing the quick pre-fixing of the electronic control component and the mounting frame 800 on the middle partition 200. Moreover, the distance between the electronic control component and the wind wheel 600 is closer, which is more conducive to the wind wheel 600 dissipating heat from the electronic control component. During the process of the first folded edge 830 moving downward in the first opening 210, the front wall and the rear wall of the first opening 210 guide the first folded edge 830, so that the first folded edge 830 can be quickly and accurately hung on the lower wall of the first opening 210. Among them, as Figure 5 and Figure 6 shown, the mounting frame 800 and the radiator 310 close the first opening 210, and the gap between the mounting frame 800 and the wall of the first opening 210 is filled with sponge for sealing.

[0040] In one embodiment, as Figure 4 shown, the upper end of the mounting frame 800 is provided with a second folded edge 840 bent toward the side where the installation cavity 120 is located. The second folded edge 840 is located above the first air guide cover 400. The operator can quickly disassemble, assemble, and move the combined structure in the installation cavity 120 by grasping the second folded edge 840.

[0041] In one embodiment, as Figures 4 to 6As shown, the lower wall of the fourth opening 820 is further provided with a third folded edge 822 that bends towards the side where the installation cavity 120 is located. The third folded edge 822 extends obliquely upwards towards the side where the installation cavity 120 is located. The electronic control board 320 is located below the third folded edge 822. In this way, the water that enters the internal flow-through air duct 550 from the fourth air outlet 520 (the speed of the water reaching the third folded edge 822 is relatively small) is blocked by the third folded edge 822 and is less likely to flow to the side where the installation cavity 120 is located and drip down onto the electronic control board 320. This solution can further improve the waterproof performance of the electronic control board 320. Among them, as Figure 4 shown, the width of the third folded edge 822 is set to 5 mm to 10 mm. Among them, if the width of the third folded edge 822 is less than 5 mm, the water-blocking effect of the third folded edge 822 becomes poor; if the width b of the third folded edge 822 is greater than 10 mm, the influence of the third folded edge 822 on the air passing effect of the first air outlet 410 is relatively large.

[0042] The air conditioner (not shown in the figure) provided by the embodiment of the present invention includes the outdoor unit of the air conditioner described in any one of the above embodiments.

[0043] This air conditioner has all the advantages of the outdoor unit of the air conditioner provided in any one of the above embodiments, which will not be elaborated here.

[0044] In summary, for the outdoor unit of the air conditioner provided by the embodiment of the present invention, the first air guide cover is located in the installation cavity and is provided at the second opening. The first air outlet faces the electronic control element, and the second air outlet is connected to the heat exchange cavity through the second opening. In this way, the air flow passing through the first air outlet, the first air guide cover, the second air outlet, and the second opening will flow through the electronic control element more, so the heat dissipation effect of the electronic control element is better.
