[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference below Figure 1-Figure 5 An air-conditioning outdoor unit 100 according to an embodiment of the first aspect of the present invention is described.

[0041] like Figure 2 and Figure 3 As shown, the air-conditioning outdoor unit 100 according to the first embodiment of the utility model includes: a housing 10 and an electronic control component 20.

[0042] Specifically, the shell 10 has a fan cavity 101 and a compressor cavity 102 arranged at intervals; the electronic control component 20 is arranged in the shell 10, and the electronic control component 20 includes a box body 21, an electrical component 22 and a radiator 23, the box body 21 has an installation cavity 201 and a heat dissipation duct 202, the electrical component 22 is arranged in the installation cavity 201, the radiator 23 is arranged on the outside of the installation cavity 201 and is located in the fan cavity 101, and the heat dissipation duct 202 is arranged on the outside of the installation cavity 201, wherein the two ends of the heat dissipation duct 202 are respectively formed as a first inlet 2021 and a first outlet 2022, the first inlet 2021 is connected to the external space of the shell 10, and the first outlet 2022 is arranged toward the radiator 23 and is connected to the fan cavity 101, and the shell 10 is formed with a second inlet and a second outlet connected to the installation cavity 201, and the second outlet is connected to the fan cavity 101.

[0043] For example, the housing 10 has a cavity, the middle partition 12 is disposed in the housing 10 and divides the cavity of the housing 10 into a fan cavity 101 and a compression cavity, wherein the fan cavity 101 and the compression cavity can be arranged in a left-right interval, the fan assembly 50 and the outdoor heat exchanger of the air-conditioning outdoor unit 100 can be disposed in the fan cavity 101, and the compressor assembly 60 of the air-conditioning outdoor unit 100 can be disposed in the compressor cavity 102. Optionally, the electric control assembly 20 can be disposed on the top of the middle partition 12 and at least partially supported on the middle partition 12.

[0044] The electrical components 22 are all installed in the installation cavity 201 of the box body 21. Furthermore, the electrical components 22 are located in the compressor cavity 102. The electrical components 22 are power components and generate heat when working. The radiator 23 is arranged outside the installation cavity 201 to dissipate heat for the electrical components 22. For example, the electric control component 20 also includes a circuit board, and the electrical components 22 are all arranged on the circuit board. The radiator 23 is connected to the circuit board to dissipate heat for the circuit board.

[0045] The box body 21 defines a heat dissipation duct 202 and an installation cavity 201 that are not connected to each other, wherein the heat dissipation duct 202 is connected to the external space through a first inlet 2021, and is connected to the radiator 23 through a first outlet 2022. When the fan assembly 50 in the fan cavity 101 is running, driven by the fan assembly 50, external air can enter the heat dissipation duct 202 through the first inlet 2021, and then blow out toward the radiator 23 from the first outlet 2022. In this way, compared with using the high-temperature air in the compressor cavity 102 to dissipate the heat of the radiator 23, this embodiment can use external normal temperature air to dissipate the heat of the radiator 23, avoiding the mixing of the high-temperature air in the compressor cavity 102. In addition, the independent heat dissipation duct 202 can provide a more stable laminar airflow, improve the heat exchange efficiency of the radiator 23, and improve the heat dissipation effect of the radiator 23 on the electrical components 22.

[0046] The installation cavity 201 can be connected to the external space through the second inlet, and connected to the fan cavity 101 through the second outlet. When the fan assembly 50 in the fan cavity 101 is running, driven by the fan assembly 50, external air can enter the installation cavity 201 through the second inlet, and then blow out toward the fan cavity 101 from the second outlet. In this way, the external air can be used to dissipate heat for the electrical components 22 in the installation cavity 201, stabilize the temperature in the installation cavity 201, improve the working stability of the electrical components 22, and ensure the operating frequency of the compressor.

[0047] That is to say, two air ducts are provided in the electrical control component 20 of the air conditioner outdoor unit 100: an installation cavity 201 and a heat dissipation duct 202, wherein the installation cavity 201 not only provides an installation space for the electrical component 22, but also can be connected to the external space and the fan cavity 101 through the second outlet and the second inlet respectively. In this way, the installation cavity 201 can be used as a heat exchange flow channel to provide low-temperature airflow for the electrical component 22 in the installation cavity 201 for heat exchange, so as to reduce the ambient temperature of the electrical component 22 and improve the working stability of the electrical component 22. At the same time, the heat dissipation duct 202 can be used to provide low-temperature airflow for the radiator 23 to improve the heat dissipation performance of the radiator 23.

[0048] Therefore, the electrical component 22 can not only exchange heat through the air flow flowing in the heat exchange channel composed of the second inlet, the installation cavity 201 and the second outlet, but also dissipate heat through the radiator 23 with heat exchange of the heat dissipation duct 202, thereby improving the heat dissipation effect of the electrical component 22, stabilizing the ambient temperature of the electrical component 22, improving the working stability of the electrical component 22, and ensuring the operating frequency of the compressor.

[0049] According to the air-conditioning outdoor unit 100 of the embodiment of the utility model, the installation cavity 201 is connected to the fan cavity 101 and the external space through the second inlet and the second outlet respectively, and a heat dissipation channel is provided outside the installation cavity 201, and the radiator 23 is connected to the external space through the heat dissipation channel. Therefore, on the one hand, the air volume passing through the radiator 23 is increased and the temperature of the fluid passing through the radiator 23 is reduced. On the other hand, the ambient temperature of the electrical component 22 can be reduced, thereby improving the heat dissipation of the electronic control component 20 and improving the working stability of the electronic control component 20.

[0050] In one embodiment of the present invention, Figure 3 As shown, the box body 21 may include a box body and an air duct member, wherein the box body defines a mounting cavity 201, the air duct member is connected to the box body, and the air duct member cooperates with the box body to define a heat dissipation air duct 202, or the air duct member defines the heat dissipation air duct 202. The air duct member may be integrally formed with the box body, or the air duct member may be a separate member from the box body, and when the air duct member and the box body are separate members, the air duct member and the box body are detachably connected.

[0051] Furthermore, when the air duct member may be in the shape of a hollow tube with both ends open, the inner side of the air duct member defines a heat dissipation air duct 202 .

[0052] In one embodiment of the present invention, Figure 3 As shown, the heat dissipation duct 202 can be arranged at the lower side of the installation cavity 201. Thus, the space on the upper side of the compressor assembly 60 can be utilized, with a compact structure and reasonable layout.

[0053] In one embodiment of the present invention, Figure 3 As shown, the heat dissipation duct 202 may include a first section 2023 and a second section 2024. The first section 2023 extends in a horizontal direction, and the second section 2024 is connected to the downstream of the first section 2023 in the airflow direction. Along the airflow direction, the second section 2024 extends upwardly and obliquely away from the first section 2023 toward the radiator 23.

[0054] Driven by the fan assembly 50, the external air first enters the first section 2023 from the first inlet 2021, flows in the horizontal direction, then enters the second section 2024 and flows upwardly obliquely, and finally blows toward the radiator 23. Among them, since the air flows upwardly obliquely in the second section 2024, at this time, the gas in the air can flow upward, and the dust and other impurities in the air will settle in the second section 2024 under the action of gravity, thereby playing the role of gas-solid separation in the air, reducing the dust entering the radiator 23, and ensuring the heat exchange performance of the radiator 23.

[0055] In one embodiment of the present invention, referring to Figure 3 The heat sink 23 has fins, and the extending direction of the fins is parallel to the air outlet direction of the first outlet 2022. For example, the air outlet direction of the first outlet 2022 is in the horizontal direction, for example Figure 3 In the left and right directions shown in , the radiator 23 includes a plurality of fins, the fins may be arranged vertically and extend left and right, the plurality of fins may be arranged at intervals in the front-to-back direction, or the fins may be arranged horizontally and extend front-to-back, and the plurality of fins may be arranged at intervals in the up-down direction. In this embodiment, by making the fins parallel to the flow direction of the airflow of the first outlet 2022, the resistance of the radiator 23 to the airflow of the second outlet may be reduced, the air volume of the second outlet may be increased, and the heat dissipation efficiency of the radiator 23 may be improved.

[0056] In one embodiment of the utility model, a grille member (not shown) is connected to the periphery of the second outlet, and the grille member has a plurality of ribs extending horizontally, and the plurality of ribs are arranged in the up and down directions, and in the direction from the second outlet toward the fan cavity 101, the ribs extend downwardly at an angle.

[0057] Compared with the fully open second outlet, a grille member is connected to the periphery of the second outlet, and the grille member can play a blocking role at the second outlet position, reducing the impurities or rainwater in the fan chamber 101 from entering the installation chamber 201, and reducing the influence of impurities and rainwater on the operation of the electrical components 22 in the installation chamber 201. At the same time, the grille holes formed by the grille member can make the air entering the installation chamber 201 from the second inlet blow out from the second outlet smoothly, realize the heat dissipation of the electrical components 22 in the installation chamber 201, and reduce the ambient temperature in the installation chamber 201.

[0058] At the same time, the grille member has a plurality of ribs, and the plurality of ribs can extend in the horizontal direction and be arranged in sequence in the up and down directions, and the plurality of ribs extend downwardly at an angle along the air outlet direction of the second outlet. In this way, along the air outlet direction of the second outlet, grille holes extending downwardly at an angle can be defined between adjacent ribs. At this time, in the direction from the fan cavity 101 to the installation cavity 201, the grille holes extend upwardly at an angle, thereby further preventing rainwater and impurities on one side of the fan cavity 101 from entering the installation cavity 201 through the second outlet, thereby ensuring the normal operation of the electrical components 22 in the installation cavity 201.

[0059] It should be noted that, in addition to the electrical components 22 connected to the radiator 23, the remaining components of the circuit board also need to dissipate heat. However, this part of the components is directly exposed to the air and is easily contaminated by dust from the external unit. Therefore, in one embodiment of the utility model, the air conditioner outdoor unit 100 may also include: a filter 30, and the filter 30 is configured to filter the air entering the second inlet. For example, the filter 30 can be arranged in the installation cavity 201 and cover the second inlet. The filter 30 can also be arranged on the outside of the installation cavity 201 and cover the second inlet. Of course, the filter 30 can also be arranged on the upstream side of the second inlet and away from the second inlet to filter the air leading to the second inlet. In this embodiment, by setting the filter 30 to filter the air at the second inlet position, the dust impurities in the air entering the installation cavity 201 can be reduced, the problem of dust accumulation of the electrical components 22 in the installation cavity 201 can be avoided, the pollution of the electrical components 22 can be effectively reduced, and the heat exchange efficiency between the electrical components 22 and the airflow in the installation cavity 201 can be improved, so that the electrical components 22 can operate in a suitable temperature environment.

[0060] Furthermore, the filter element 30 may be a filter net or a sponge element, etc. Thus, the structure of the filter element 30 can be simplified and the cost can be reduced.

[0061] In one embodiment of the present invention, the first inlet 2021 and the second inlet are both formed on the side plate 11 of the shell 10. For example, the first inlet 2021 and the second inlet can penetrate the side plate 11 located on the right side of the shell 10 in the left-right direction.

[0062] The air conditioner outdoor unit may further include: a cover plate 40, the cover plate 40 is connected to the shell 10 and is arranged on the outside of the shell 10, the cover plate 40 cooperates with the side plate 11 to define a first air inlet duct 401 and a second air inlet duct 402 separated from each other, a first air inlet port 403 and a second air inlet port 404 are formed on the cover plate 40, the first air inlet duct 401 is connected between the first air inlet port 403 and the first inlet 2021, and the second air inlet duct 402 is connected between the second air inlet port 404 and the second inlet.

[0063] When the fan assembly 50 is running, external air can enter the first air inlet duct 401 through the first air inlet 403, then enter the heat dissipation duct 202 through the first inlet 2021, and finally blow toward the radiator 23 from the first outlet 2022. By providing the cover plate 40 and defining the first air inlet duct 401 between the cover plate 40 and the side plate 11, the distance between the first air inlet 403 and the first outlet 2022 can be extended, thereby allowing dust, rainwater, etc. in the air to settle and separate in the first air inlet duct 401 and the heat dissipation duct 202, thereby preventing rainwater, dust, etc. from entering the radiator 23 and affecting the heat dissipation performance of the radiator 23.

[0064] At the same time, when the fan assembly 50 is running, the external air can enter the second air inlet duct 402 through the second air inlet 404, then enter the installation cavity 201 through the second inlet, and finally flow from the second outlet to the fan cavity 101. In this way, by setting the cover plate 40 and defining the second air inlet duct 402 between the cover plate 40 and the side plate 11, the distance between the second inlet and the second air inlet 404 can be extended, thereby allowing dust, rainwater, etc. in the air to settle and separate in the second air inlet duct 402, preventing rainwater, dust, etc. from entering the installation cavity 201 and affecting the electrical components 22 in the installation cavity 201.

[0065] In one embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the air conditioner outdoor unit 100 may further include a filter element 30, which is disposed in the second air inlet duct 402 and completely covers the second air inlet 404. In this embodiment, by arranging the filter element 30 to cover the second air inlet 404, the filter element 30 can filter the air entering the second air inlet 404, thereby reducing dust impurities in the air entering the installation cavity 201, avoiding dust accumulation of the electrical components 22 in the installation cavity 201, improving the heat exchange efficiency between the electrical components 22 and the airflow in the installation cavity 201, and allowing the electrical components 22 to operate in a suitable temperature environment.

[0066] In one embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the first air inlet 403 and the second air inlet 404 both penetrate the outer bottom surface of the cover plate 40 in the up-down direction. For example, the cover plate 40 may include a main plate portion and a flange, the main plate portion is vertically arranged and extends front and back, the flange is connected to the periphery of the main plate portion and extends in a ring shape along the circumference of the main plate portion, the flange located at the lower side of the main plate portion is the first flange, and the first air inlet 403 and the second air inlet 404 both penetrate the first flange in the up-down direction.

[0067] In this embodiment, the first air inlet 403 and the second air inlet 404 pass through the outer bottom surface of the cover plate 40, so that the openings of the first air inlet 403 and the second air inlet 404 are both set downward, thereby effectively preventing external rainwater from entering the first air inlet duct 401 and the second air inlet duct 402.

[0068] In one embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, in the direction from the first air inlet 403 toward the first inlet 2021, at least a portion of the first air inlet duct 401 extends upward; in the direction from the second air inlet 404 toward the second inlet, at least a portion of the second air inlet duct 402 extends upward.

[0069] That is to say, along the air flow direction, a part of the first air inlet duct 401 may extend upward, or the entire first air inlet duct 401 may extend upward. After the external air enters the first air inlet duct 401 through the first air inlet 403, the air flow flows in the upward direction in the first air inlet duct 401, at least in the air duct section extending upward therein, so that, on the one hand, dust can be settled in the upwardly extending area, reducing the dust entering the heat dissipation duct 202, and on the other hand, it can prevent external rainwater from entering the heat dissipation duct 202, thereby preventing dust and rainwater in the external air from entering the radiator 23, thereby ensuring the heat exchange performance of the radiator 23.

[0070] Similarly, along the air flow direction, a portion of the second air inlet duct 402 may extend upward, or the entire second air inlet duct 402 may extend upward. After external air enters the second air inlet duct 402 through the second air inlet 404, the air flow may flow in an upward direction in the second air inlet duct 402, at least in the air duct section extending upward therein. In this way, on the one hand, dust can be settled in the upwardly extending area to reduce dust entering the installation cavity 201, and on the other hand, external rainwater can be prevented from entering the installation cavity 201, thereby preventing dust and rainwater in the external air from entering the installation cavity 201, thereby ensuring the normal operation of the electrical components 22 in the installation cavity 201.

[0071] In one embodiment of the present invention, referring to Figure 4 and Figure 5As shown, the cover plate 40 may include: a cover body 41 and a fireproof member 42 stacked along the thickness direction of the cover plate 40, the fireproof member 42 is arranged on the side of the cover body 41 facing the side plate 11, and the first air inlet duct 401 and the second air inlet duct 402 are formed between the fireproof member 42 and the side plate 11. Among them, the fireproof member 42 can be a fireproof sheet metal, and the fireproof member 42 has good fireproof performance. The cover plate 40 of this embodiment is formed by the cover body 41 and the fireproof member 42 being stacked in two layers, and the first air inlet duct 401 and the second air inlet duct 402 are enclosed by the fireproof member 42 and the side plate 11, thereby not only improving the structural strength of the cover plate 40, but also improving the protection performance.

[0072] In a specific embodiment, the cover body 41 and the fireproof member 42 are detachably connected. For example, the cover body 41 and the fireproof member 42 can be connected by snapping, or the cover body 41 and the fireproof member 42 can be connected by fasteners. Thus, the assembly efficiency between the cover body 41 and the fireproof member 42 can be improved.

[0073] For example, the cover body 41 is formed into a structure that is recessed away from the fireproof part 42, and the fireproof part 42 is formed into a structure that is recessed toward the cover body 41 and fits into the groove structure of the cover body 41, wherein the periphery of the fireproof part 42 is formed with a folded edge folded in the up and down directions, and a first connecting hole is formed on the folded edge, and a second connecting hole is formed on the cover body 41, and the first connecting hole and the second connecting hole are aligned in the thickness direction of the cover body 41, and the fireproof part 42 is fixed to the cover body 41 by fasteners passing through the first connecting hole and the second connecting hole.

[0074] Furthermore, the lower peripheral edge of the fireproof component 42 is provided with two folded edges extending downward, the two folded edges are arranged between the front and the back, and the first connecting holes are formed on the two folded edges.

[0075] In one embodiment of the utility model, a handle 43 is provided on the side of the cover plate 40 away from the housing 10. For example, the handle 43 is formed as a convex rib protruding from the surface of the side of the cover plate 40 away from the housing 10, and the handle 43 extends downwardly in a direction from the housing 10 toward the cover plate 40. Thus, it is convenient for an operator to grasp the cover plate 40 through the handle 43 to prevent the cover plate 40 from slipping.

[0076] The following will refer to Figure 1-Figure 5 An air-conditioning outdoor unit 100 according to a specific embodiment of the present invention is described.

[0077] Reference Figure 2 The air conditioner outdoor unit 100 includes: a housing 10, an electronic control component 20, a fan component 50, a compressor component 60 and a cover plate 40.

[0078] Specifically, Figure 1As shown, a middle partition plate 12 is provided in the housing 10, and the middle partition plate 12 divides the housing 10 into a fan chamber 101 and a compressor chamber 102. The fan assembly 50 is provided in the fan chamber 101, and the compressor assembly 60 is provided in the compressor chamber 102.

[0079] The electric control assembly 20 is arranged in the housing 10 and above the middle partition 12. The electric control assembly 20 includes a box body 21, an electrical component 22 (power component) and a radiator 23. The radiator 23 is connected to the electrical component 22 and is located in the air duct cavity, and is arranged outside the box body 21 for heat dissipation. The box body 21 defines a non-connected installation cavity 201 and a heat dissipation air duct 202. The electrical component 22 is arranged in the installation cavity 201. The electrical component 22 in the electric control box that is not connected to the radiator 23 is located in the compressor cavity 102.

[0080] The cover plate 40 is arranged outside the housing 10, and cooperates with the housing 10 to define a first air inlet duct 401 and a second air inlet duct 402 that are not connected to each other. The bottom of the cover plate 40 is formed with a first air inlet 403 connected to the first air inlet duct 401 and a second air inlet 404 connected to the second air inlet duct 402. The first air inlet 403 and the second air inlet 404 are arranged at intervals in front and back. A filter 30 is provided at the second air inlet 404.

[0081] The heat dissipation duct 202 is connected to the first air inlet duct 401 through the first inlet 2021 and is connected to the fan cavity 101 and the radiator 23 through the first outlet 2022 . The second air inlet duct 402 of the installation cavity 201 is connected to the installation cavity 201 through the second inlet.

[0082] The installation cavity 201 is communicated with the second air inlet duct 402 through the second inlet, and is connected to the fan cavity 101 through the second outlet. A grille is provided at the second outlet, and the grille has ribs extending downwardly along the airflow direction.

[0083] According to the air conditioner outdoor unit 100 of the embodiment of the utility model, the electric control component 20 uses a dual-channel ventilation structure to dissipate heat from the electrical components 22 in the electric control component 20. On the one hand, it is to increase the air volume passing through the radiator 23 and reduce the temperature of the fluid passing through the radiator 23. On the other hand, it is conducive to reducing the dust content in the airflow passing through the electrical components 22 and improving the reliability of the electric control component 20.

[0084] Since the electronic control component 20 has a dual-channel ventilation structure, when the performance of the filter element 30 decays, the radiator 23 can still inhale the airflow from the condenser end and the airflow from the chassis gap of the compressor chamber 102 through the first air inlet duct 401 and the heat dissipation duct 202, thereby ensuring reliable heat dissipation performance.
