Description

Technical Field

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

[0002] A split-type air conditioner includes an indoor unit and an outdoor unit. The outdoor unit is usually equipped with a partition to divide the space inside the casing into two chambers. One chamber is used to set up a heat exchanger and a fan, etc., and the other chamber is used to set up a compressor and an electronic control box, etc. The heat exchanger is used to exchange heat between the refrigerant and the outdoor environment, the fan is used to accelerate the gas flow to improve the heat exchange efficiency, the compressor is used to compress the refrigerant, and the electronic control box is used to control the compressor and the fan, etc.

[0003] Among them, the electronic components arranged on the PCB board of the electric control box need to work normally and stably at an appropriate temperature. However, in the air-conditioning outdoor unit in the prior art, the heat dissipation efficiency of the electric control box is relatively low, and the heat dissipation effect is relatively poor, which affects the normal and stable operation of the electric control box. Utility Model Content

[0004] The purpose of the utility model is to provide an air-conditioning outdoor unit to solve the technical problems of low heat dissipation efficiency and poor heat dissipation effect of the electric control box of the air-conditioning outdoor unit in the prior art.

[0005] The utility model provides an air-conditioning outdoor unit, comprising a casing and an electrical control box, the casing comprising a side panel, the side panel being provided with a first air inlet and a second air inlet; the electrical control box being provided with a component cavity and a heat dissipation channel, the component cavity being provided with a third air inlet and at least one air outlet; a PCB board being provided in the component cavity, and a radiator being provided in the component cavity corresponding to the PCB board; the electrical control box being mounted on the inner wall of the side panel, and the third air inlet being connected to the first air inlet; the air inlet end of the heat dissipation channel being connected to the second air inlet; and the radiator being at least partially located in the heat dissipation channel.

[0006] The air conditioner outdoor unit provided by the utility model can produce the following beneficial effects:

[0007] The air conditioner outdoor unit provided by the utility model has two ventilation channels for heat dissipation, wherein the air flow direction in one channel is as follows: external air enters the component cavity through the first air inlet on the side panel and the third air inlet of the component cavity in sequence, exchanges heat with the PCB board and the electronic components thereon in the component cavity, and is then discharged through the air outlet of the component cavity. The air in the channel directly exchanges heat with the PCB board and the electronic components thereon in the component cavity, thereby quickly reducing the temperature of the PCB board and the electronic components thereon. The air flow direction in the other channel is as follows: external air enters the heat dissipation channel from the air inlet end of the heat dissipation channel through the second air inlet on the side panel, exchanges heat with the radiator therein, and is then discharged from the air outlet end of the heat dissipation channel. The air in the heat dissipation channel exchanges heat with the radiator, thereby accelerating the heat dissipation of the radiator, thereby improving the heat dissipation efficiency of the radiator for the PCB board and the electronic components thereon. It can be seen that the air-conditioning outdoor unit provided by the utility model increases the flow rate of the heat exchange gas by setting two ventilation channels for heat dissipation, and also directly and indirectly accelerates the heat dissipation efficiency of the PCB board and the electronic components thereon, so the heat dissipation effect is good.

[0008] Furthermore, the air-conditioning outdoor unit also includes an electrical cover, which is fixedly arranged on the side panel and encloses an air inlet cavity therebetween with the side panel, and the first air inlet is connected to the air inlet cavity; a fourth air inlet is provided on the bottom plate of the electrical cover, and after the external air enters the air inlet cavity from the fourth air inlet, it enters the element cavity through the first air inlet and the third air inlet in sequence.

[0009] Under this technical solution, firstly, the electrical cover can prevent water and other debris from entering the component cavity of the electrical control box through the first air inlet on the side panel and the third air inlet on the electrical control box, thereby protecting the electrical control box; secondly, an air inlet cavity is enclosed between the electrical cover and the side panel, providing an air inlet channel for external gas to enter the component cavity, and, moreover, the fourth air inlet on the electrical cover that is connected to the air inlet cavity is opened on the bottom plate of the electrical cover, which can effectively prevent rain and debris from entering the air inlet cavity through the fourth air inlet.

[0010] Furthermore, the electrical control box includes a box body; the opening of the box body is arranged opposite to the first air inlet, and the opening forms the third air inlet; and / or, the side panel is provided with a first inspection port, the first inspection port is arranged opposite to the third air inlet, and the first inspection port forms the first air inlet.

[0011] When the first inspection port opened on the side panel serves as the first air inlet, it plays the dual role of air inlet and inspection window. After the electrical cover is removed, the electric control box can be inspected through the first air inlet on the side panel, i.e. the first inspection port, and the opening of the electric control box without removing the electric control box from the casing, which is very convenient and quick.

[0012] Optionally, the electrical control box includes a box body and a box cover, the box cover is arranged on the box body and closes the opening of the box body; the box cover is provided with a ventilation port or a second inspection port, the ventilation port or the second inspection port is arranged opposite to the first air inlet, and the ventilation port or the second inspection port forms the third air inlet; and / or, the side panel is provided with a first inspection port, the first inspection port is arranged opposite to the third air inlet, and the first inspection port forms the first air inlet.

[0013] When the box cover is provided with a vent, the gas in the air inlet cavity enters the component cavity through the vent.

[0014] When the box cover is provided with a second inspection port and the side panel is provided with a first inspection port, after removing the electrical cover, the electric control box can be inspected through the first air inlet on the side panel, i.e., the first inspection port, and the second inspection port on the box cover.

[0015] Furthermore, the heat dissipation channel includes a connected horizontal section and a vertical section, the horizontal section is located above the element cavity, and the upper wall of the element cavity separates the element cavity and the horizontal section; the vertical section is arranged on the side of the element cavity away from the side plate, and the side wall of the element cavity separates the element cavity and the vertical section; the side wall is provided with an avoidance opening for avoiding the radiator; the radiator is arranged in the vertical section after passing through the avoidance opening.

[0016] Under this technical solution, because the hot air in the component cavity will rise, the temperature of the upper wall of the component cavity will be slightly higher. The heat dissipation channel is set above the component cavity. The airflow entering the horizontal section of the heat dissipation channel will first cool down the upper wall, and then enter the vertical section of the heat dissipation channel and then exchange heat with the radiator to quickly dissipate the heat on the radiator.

[0017] Furthermore, the component cavity is provided with a first air outlet, which is opened on the front wall and / or rear wall of the electrical control box; and / or the component cavity is provided with a second air outlet, which is opened on the upper wall of the electrical control box and connects the component cavity and the heat dissipation channel.

[0018] Under this technical solution, the gas in the component cavity can be discharged to the outside of the electrical control box from the first air outlet, or it can flow into the heat dissipation channel from the second air outlet on the upper wall. Among them, the setting of the second air outlet can effectively avoid the situation where the gas is retained at the top of the component cavity, thereby greatly improving the fluidity of the gas in the component cavity and thus ensuring the heat dissipation effect.

[0019] Furthermore, the second air outlet is arranged on the front side and / or rear side of the upper wall.

[0025] Furthermore, the interior of the casing is an integrated cavity, the heat exchanger and the fan of the air-conditioning outdoor unit are located on the left side of the integrated cavity, and the electric control box and the compressor of the air-conditioning outdoor unit are located on the right side of the integrated cavity.

[0026] Under this technical solution, the air-conditioning outdoor unit has eliminated the setting of the wind-blocking vertical plate, and the space inside the casing is not divided into two chambers. This not only reduces costs and simplifies the assembly process, but also helps to make more effective use of the space inside the outdoor unit and reduce the overall size of the outdoor unit.

[0027] Furthermore, the side panel includes a left panel and a right panel, and the electric control box is fixedly connected to the inner wall of the right panel; the first air inlet and the second air inlet are both opened on the right panel.

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] First of all, it should be noted that in the drawings, the directions indicated by the arrows "ab" are left and right directions, the directions indicated by the arrows "cd" are front and rear directions, and the directions indicated by the arrows "ef" are up and down directions.

[0053] This embodiment provides an air conditioner outdoor unit, such as Figures 1 to 10 As shown, the air-conditioning outdoor unit includes a casing and an electrical control box 200, the casing includes a side panel, and the side panel is provided with a first air inlet 121 and a second air inlet 122; the electrical control box 200 is provided with a component cavity 201 and a heat dissipation channel 202, and the component cavity 201 is provided with a third air inlet and at least one air outlet; a PCB board 230 is provided in the component cavity 201, and a radiator 240 is provided at the component cavity 201 corresponding to the PCB board 230; the electrical control box 200 is installed on the inner wall of the side panel, and the third air inlet is connected to the first air inlet 121; the air inlet end of the heat dissipation channel 202 is connected to the second air inlet 122; the radiator 240 is at least partially located in the heat dissipation channel 202.

[0054] The air conditioner outdoor unit provided in this embodiment has two ventilation channels for heat dissipation, and the air flow direction in one of the channels is as follows: the external air enters the component cavity 201 through the first air inlet 121 on the side panel and the third air inlet of the component cavity 201 in sequence, exchanges heat with the PCB board 230 and the electronic components thereon in the component cavity 201, and is discharged through the air outlet of the component cavity 201. The air in this channel directly exchanges heat with the PCB board 230 and the electronic components thereon in the component cavity 201, so that the heat of the PCB board 230 can be quickly reduced. 0 and the temperature of the electronic components thereon; the airflow direction in the other channel is as follows: external air enters the heat dissipation channel 202 from the air inlet end of the heat dissipation channel 202 through the second air inlet 122 on the side panel, exchanges heat with the radiator 240 in the heat dissipation channel 202, and is then discharged from the air outlet end of the heat dissipation channel 202. The air in the heat dissipation channel 202 exchanges heat with the radiator 240, thereby accelerating the heat dissipation of the radiator 240, and further improving the heat dissipation efficiency of the radiator 240 for the PCB board 230 and the electronic components thereon. It can be seen that the air conditioner outdoor unit provided in this embodiment, by providing two ventilation channels for heat dissipation, increases the flow rate of the heat exchange gas, and also directly and indirectly accelerates the heat dissipation efficiency of the PCB board 230 and the electronic components thereon, thereby achieving a good heat dissipation effect.

[0055] More specifically, in this embodiment, the third air inlet is disposed opposite the first air inlet 121, and the air inlet end of the heat dissipation channel 202 is disposed opposite the second air inlet 122. However, in other embodiments of the present application, the third air inlet may not be disposed opposite the first air inlet 121, as long as they are connected; and the air inlet end of the heat dissipation channel 202 may not be disposed opposite the second air inlet 122, as long as they are connected.

[0056] Specifically, in this embodiment, Figure 1 and Figure 2As shown, the air conditioner outdoor unit also includes an electrical cover 300, which is fixedly arranged on the side panel and encloses an air inlet cavity 301 therebetween with the side panel, and the first air inlet 121 is connected to the air inlet cavity 301; the bottom plate 310 of the electrical cover 300 is provided with a fourth air inlet 302, and after the external air enters the air inlet cavity 301 from the fourth air inlet 302, it enters the element cavity 201 in sequence through the first air inlet 121 and the third air inlet. Under this setting, firstly, the electrical cover 300 can prevent water and other debris from entering the component cavity 201 of the electrical control box 200 through the first air inlet 121 on the side panel and the third air inlet on the electrical control box 200, thereby protecting the electrical control box 200; secondly, an air inlet cavity 301 is enclosed between the electrical cover 300 and the side panel, providing an air inlet channel for external gas to enter the component cavity 201, and, moreover, the fourth air inlet 302 on the electrical cover 300, which is connected to the air inlet cavity 301, is opened on the bottom plate 310 of the electrical cover 300, which can effectively prevent rain and debris from entering the air inlet cavity 301 through the fourth air inlet 302.

[0057] Specifically, in this embodiment, Figure 6 、 Figure 8 and Figure 10 As shown, the electrical control box 200 includes a box body 210; an opening 217 of the box body 210 is arranged opposite the first air inlet 121, forming a third air inlet; and a first inspection port is provided on the side panel. The first inspection port is arranged opposite the third air inlet, forming the first air inlet 121. In this arrangement, the first air inlet 121 serves as both an air inlet and an inspection window. After removing the electrical cover 300, the electrical control box 200 can be inspected and maintained through the first air inlet 121 on the side panel (i.e., the first inspection port) and the opening 217 of the electrical control box 200, without having to remove the electrical control box 200 from the housing, which is very convenient and quick. Of course, in other embodiments of the present application, the first air inlet 121 may not serve as an inspection window. For example, the first air inlet 121 may be in the form of a shutter or an air inlet grille. As for the third air inlet of the electrical control box 200, it may not be an opening 217, but a specially arranged air inlet.

[0058] Optionally, Figure 11 FIG. 4 shows another form of the air conditioner outdoor unit provided in this embodiment, such as Figure 11As shown, the electrical control box 200 includes not only a housing 210 but also a cover 290. The cover 290 is mounted on the housing 210 and seals the opening 217 of the housing 210. The cover 290 defines a vent 291, which is positioned opposite the first air inlet 121 and forms a third air inlet. In this configuration, air within the air inlet chamber 301 enters the component chamber 201 through the vent 291. Alternatively, the cover 290 may be provided with a second inspection port, which forms the third air inlet and is positioned opposite the first air inlet 121 (i.e., the first inspection port). In this manner, even after removing the electrical cover 300, the electrical control box 200 can still be inspected through the first air inlet 121 (i.e., the first inspection port) on the side panel and the second inspection port on the cover 290.

[0059] Specifically, in this embodiment, Figure 8 As shown, the second air inlet 122 is in the form of a long slot along the horizontal direction. However, in other embodiments of the present application, the form of the second air inlet 122 is not limited thereto. For example, the second air inlet 122 can also be in the form of a shutter or an air inlet grille.

[0060] Specifically, in this embodiment, Figure 2 and Figure 4 As shown, the heat dissipation channel 202 includes a connected horizontal section 203 and a vertical section 204. The horizontal section 203 is located above the component cavity 201, and the upper wall 214 of the component cavity 201 separates the component cavity 201 and the horizontal section 203; the vertical section 204 is arranged on the side of the component cavity 201 away from the side plate, and the side wall 216 of the component cavity 201 separates the component cavity 201 and the vertical section 204; the side wall 216 is provided with an avoidance opening for avoiding the radiator 240; the radiator 240 is arranged in the vertical section 204 after passing through the avoidance opening. Under this arrangement, since the hot air in the component cavity 201 will rise, the temperature of the upper wall 214 of the component cavity 201 will be slightly higher. Since the heat dissipation channel 202 is arranged above the component cavity 201, the airflow entering the horizontal section 203 of the heat dissipation channel 202 will first cool down the upper wall 214, and then enter the vertical section 204 of the heat dissipation channel 202, and then exchange heat with the radiator 240, so that the heat on the radiator 240 can be quickly dissipated.

[0061] More specifically, in this embodiment, Figures 3 to 7As shown, the box body 210 of the electric control box 200 includes a front wall 211 and a rear wall 212 spaced apart and arranged opposite to each other in the front-to-back direction, a top wall 213, an upper wall 214 and a lower wall 215 arranged in sequence in the up-down direction, the front wall 211 is connected to the front ends of the top wall 213, the upper wall 214 and the lower wall 215, the rear wall 212 is connected to the rear ends of the three, and the side of the front wall 211, the rear wall 212, the upper wall 214 and the lower wall 215 away from the side plate is connected to the side wall 216. In this way, the front wall 211, the upper wall 214 and the lower wall 215 are connected to each other. The front wall 214, the rear wall 212, the lower wall 215, and the side walls 216 collectively form the component cavity 201; the top of the front wall 211, the top wall 213, the top of the rear wall 212, and the upper wall 214 collectively form the horizontal section 203 of the heat dissipation channel 202; the end of the top wall 213 away from the side plate first extends in a direction away from the side wall 216 to form an extended section, and then the three sides of the extended section not connected to the top wall 213 all extend downward, and then together with the side walls 216 form the vertical section 204 of the heat dissipation channel 202.

[0062] Specifically, in this embodiment, Figure 6 and Figure 7 as well as Figure 9 and Figure 10 As shown, the component chamber 201 is provided with two air outlets, namely a first air outlet 218 and a second air outlet 219. The first air outlet 218 is provided on the front wall 211 of the electrical control box 200; the second air outlet 219 is provided on the upper wall 214 of the electrical control box 200 and connects the component chamber 201 with the heat dissipation channel 202. In this arrangement, the gas within the component chamber 201 can be discharged to the outside of the electrical control box 200 through the first air outlet 218 on the front wall 211, or can flow into the heat dissipation channel 202 through the second air outlet 219 on the upper wall 214. The provision of the second air outlet 219 effectively prevents gas from being retained at the top of the component chamber 201, thereby greatly improving the fluidity of the gas within the component chamber 201 and ensuring effective heat dissipation.

[0063] It should also be noted that, in other embodiments of the present application, the first air outlet 218 may also be provided on the rear wall 212, or both the front wall 211 and the rear wall 212 of the electric control box 200 may be provided with the first air outlet 218. In addition, in other embodiments of the present application, only the first air outlet 218 or only the second air outlet 219 may also be provided.

[0064] More specifically, in this embodiment, Figure 6 and Figure 7As shown, the first air outlet 218 includes multiple first air outlet holes, which are spaced apart vertically on the front wall 211. This ensures that gases at different heights within the element cavity 201 are discharged in a timely manner. Furthermore, in this embodiment, the first air outlet holes are rectangular. Of course, in other embodiments of the present application, they may also be circular or have other shapes. Furthermore, in other embodiments of the present application, the first air outlet 218 may include only one first air outlet hole, for example, the first air outlet hole may be elongated vertically.

[0065] Specifically, in this embodiment, Figure 9 and Figure 10 As shown, the second air outlet 219 is disposed on the front side of the upper wall 214. Furthermore, the second air outlet 219 includes a plurality of second air outlet holes, which are spaced apart along the left-right direction on the upper wall 214. This facilitates the flow of gas at different depths within the component cavity 201 into the heat dissipation channel 202. Furthermore, in this embodiment, the second air outlet hole is also rectangular. Of course, in other embodiments of the present application, it can also be circular or in other shapes. In addition, in other embodiments of the present application, the second air outlet 219 can also include only one second air outlet hole, for example, the second air outlet hole is elongated along the left-right direction.

[0066] It should also be noted here that, in other embodiments of the present application, the second air outlet 219 can also be provided on the rear side of the upper wall 214 , or the second air outlet 219 can be provided on both the front and rear sides of the upper wall 214 .

[0067] Specifically, in this embodiment, continue as Figure 9 and Figure 10 As shown, a water retaining rib 220 is provided on one side of the upper wall 214 located at the heat dissipation channel 202 , for preventing water from entering the component cavity 201 through the second air outlet 219 .

[0068] Specifically, in this embodiment, Figure 4 and Figure 5 As shown, a glue-filled thermal conductive layer 231 is disposed between the PCB 230 and the heat sink 240. The PCB 230 is provided with glue-filling holes 232 for filling glue between the PCB 230 and the heat sink 240. The glue-filled thermal conductive layer 231 increases the contact area between the PCB 230 and the heat sink 240, thereby enabling faster heat dissipation from the heat sink 240. Furthermore, the glue-filling holes 232 are dispersed in a plurality, thereby ensuring sufficient contact between the glue-filled thermal conductive layer 231 and both the PCB 230 and the heat sink 240.

[0069] Specifically, in this embodiment, Figure 1 and Figure 2As shown, the electrical appliance cover 300 is provided with a handle 320. Under this arrangement, the entire air conditioner outdoor unit can be easily lifted and moved by the handle 320.

[0070] Specifically, in this embodiment, continue as Figure 1 and Figure 2 As shown, the interior of the casing is an integrated cavity, that is, the air-conditioning outdoor unit provided in this embodiment cancels the setting of the wind-proof vertical plate, and the space inside the casing is not divided into two chambers. This not only reduces costs and simplifies the assembly process, but also helps to make more full use of the space inside the outdoor unit and reduce the overall size of the outdoor unit.

[0071] Because it's no longer possible to install the electrical control box 200 on the windshield, this embodiment places it on the side panel of the housing. Furthermore, in this embodiment, the electrical control box 200 is installed on the right side panel 120 of the housing and is fixedly connected to the inner wall of the right side panel 120. Both the first air inlet 121 and the second air inlet 122 are located on the right side panel 120. Placing the electrical control box 200 on the right side panel 120 makes it easier for right-handed operators to remove and install the electrical control box 200. Furthermore, the heat exchanger 400 and fan 500 of the air conditioner outdoor unit are located on the left side of the integrated cavity, while the compressor 600 of the air conditioner outdoor unit is located on the right side of the integrated cavity, along with the electrical control box 200. The heat exchanger 400, fan 500, and compressor 600 are attached to the base 110 of the housing, either directly or via brackets.

[0072] However, it should be noted that in other embodiments of the present application, the electrical control box 200 can also be located on the left side panel of the housing, with the electrical control box 200 fixedly connected to the inner wall of the left side panel; the first air inlet 121 and the second air inlet 122 are both located on the left side panel. Furthermore, the heat exchanger 400 and fan 500 of the air conditioner outdoor unit are located on the right side of the integrated cavity, while the compressor 600 of the air conditioner outdoor unit and the electrical control box 200 are located on the left side of the integrated cavity. This arrangement makes it easier for left-handed operators to disassemble and assemble the electrical control box 200.

[0073] Here, it should also be noted that, in other embodiments of the present application, a wind-blocking vertical plate may also be provided inside the casing, while the electrical control box 200 is still provided on the side panel of the casing.
