Description

Technical Field

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

[0002] Typically, a split-type air conditioner consists of an indoor unit and an outdoor unit. The outdoor unit's electrical control box is typically mounted on a vertical windshield inside the outdoor unit. The vertical windshield divides the interior of the outdoor unit into two compartments, one for the air chamber and the other for the compressor.

[0003] The electrical control box houses a printed circuit board (PCB) with electronic components mounted on it. In existing air conditioner outdoor units, the front of the electrical control box, housing the electronic components, often faces the compressor cavity, while the back of the box, housing the radiator, faces the air cavity. This prevents the PCB and its components, which are located on the front of the electrical control box and are separated from the compressor cavity by a windshield, from receiving effective heat dissipation.

[0004] At the same time, the wind-blocking plate also has a certain impact on the overall layout of the air-conditioning outdoor unit components. Each component needs to maintain a certain distance from the wind-blocking plate to meet the various functions and performance requirements of the air-conditioning outdoor unit. This leads to a larger overall size of the air-conditioning outdoor unit, which restricts the development trend of the air-conditioning outdoor unit's overall refinement and miniaturization. Utility Model Content

[0005] The first object of the present invention is to provide an air conditioner outdoor unit to solve the technical problem that the PCB on the front side of the electric control box of the existing air conditioner outdoor unit and the electronic components thereon cannot obtain effective heat dissipation.

[0006] The utility model provides an air-conditioning outdoor unit, comprising a casing and an electrical control box and a fan assembly both arranged inside the casing, the electrical control box comprising a box body, the box body being mounted on a side panel of the casing, the box body and the side panel being docked to form an electronic device cavity; the side panel being provided with a wiring window communicating with the electronic device cavity, an electrical cover for sealing the wiring window being mounted on the outside of the side panel, wherein the electrical cover being provided with an air inlet communicating with the wiring window, and the box body being provided with an air outlet communicating with the interior of the casing and the electronic device cavity.

[0007] By installing the electric control box on the casing of the air-conditioning outdoor unit, opening a wiring window connected to the electronic device cavity on the side panel, opening an air inlet connected to the wiring window on the electrical cover, and opening an air outlet connected to the inside of the casing and the electronic device cavity on the box body, when the air-conditioning outdoor unit is running, under the action of the fan assembly, the wind outside the casing will enter from the air inlet opened on the electrical cover, and further flow into the electronic device cavity of the box body through the wiring window opened on the side panel, thereby dissipating heat for the PCB and electronic components in the electronic device cavity; after completing the heat exchange with the above-mentioned components, the air flows from the outlet opened in the box body to the inside of the casing, thereby achieving cooling of the components inside the electric control box.

[0008] Through the above-mentioned arrangement, the air-conditioning outdoor unit forms a heat dissipation channel from the outside of the casing - the electrical cover - the electric control box - the inside of the casing during the operation of the air-conditioning outdoor unit, thereby being able to bring out the heat inside the electric control box, so that the components inside the electric control box are effectively cooled, thereby effectively solving the problems existing in the prior art.

[0009] Furthermore, the electrical appliance cover includes a cover portion, wherein the cover portion is opposite the wiring window and spaced apart from the side panel to form a first air inlet channel; the bottom end of the cover portion is bent toward the side panel to form a bottom panel connected to the side panel, and the air inlet includes a first air inlet opened on the bottom panel. The configuration of the electrical appliance cover not only shields the wiring window, preventing impurities from entering through the wiring window and damaging the PCB and electronic components inside the electrical control box, but also forms a first air inlet channel together with the right side panel to guide external wind.

[0010] Furthermore, the appliance cover also includes a handle and a top plate, wherein the handle is arranged at an angle to the cover, the top plate connects the handle to the side panel, and a second air inlet channel connected to the first air inlet channel is formed between the top plate and the handle. The air inlet also includes a second air inlet opening located in the handle. This arrangement not only provides a point of force for operators, making it easier for them to carry the housing, but also increases the number of channels for external air to enter the electronic device cavity, allowing as much external air as possible to enter the electronic device cavity to dissipate heat from the PCB and electronic components, thereby increasing the flow of external air and improving the cooling effect.

[0011] Furthermore, the handle is tilted downwardly, away from the side panel. This arrangement not only allows the tilted handle to guide the external air to a certain extent, thereby improving the smoothness of the external air flowing from the second air inlet to the second air inlet channel, but also forms an acute angle between the handle and the cover, thereby limiting the operator's position when carrying the housing by the handle, reducing the risk of the housing falling from the operator's hands during transportation.

[0012] Furthermore, the number of the first air inlets is multiple, and the multiple first air inlets are distributed on the bottom plate. This arrangement can increase the distribution area of ​​the first air inlets on the bottom plate, thereby increasing the amount of external air entering through the first air inlets, thereby improving cooling efficiency; and / or the number of the second air inlets is multiple, and the multiple second air inlets are distributed on the handle. This arrangement can increase the distribution area of ​​the second air inlets on the handle, thereby increasing the amount of external air entering through the second air inlets, thereby improving cooling efficiency.

[0013] Furthermore, the box body includes a mounting wall opposite to the side panel and a plurality of side walls arranged around the mounting wall, wherein the mounting wall is used to mount a PCB, and the box body is docked with the side panel via the plurality of side walls; the plurality of side walls include a top wall and a bottom wall that are opposite and spaced apart in the vertical direction, and the air outlet includes a first air outlet opened on the bottom wall, the first air outlet being opposite to the electronic device cavity. By opening the first air outlet on the bottom wall opposite to the electronic device cavity, on the one hand, the flow path of the external air in the electronic device cavity can be extended, which not only increases the contact time between the external air and the PCB and electronic components, but also allows the external air to fully cover the area where the PCB and electronic components are located during the flow of the external air in the electronic device cavity, thereby ensuring sufficient heat exchange and improving the cooling effect on the electrical control box.

[0014] Furthermore, the plurality of side walls further include a front wall and a rear wall that are opposed to each other and spaced apart in the front-to-back direction, and the air outlet further includes a second air outlet located on the front wall, the bottom wall, and the rear wall, wherein the second air outlet is disposed proximate to the mounting wall. By disposing the second air outlet proximate to the mounting wall, the second air outlet is closer to the PCB, thereby allowing external air entering the electronic device cavity to flow out after sufficient heat exchange with the PCB, thereby ensuring a cooling effect on the PCB.

[0015] Furthermore, the number of the first air outlets is multiple, and the multiple first air outlets are dispersedly arranged on the bottom wall. This setting can increase the distribution area of ​​the first air outlet on the bottom wall, thereby increasing the air output of the first air outlet, so as to improve the efficiency of external wind entering the electronic device cavity, thereby achieving the purpose of improving the cooling efficiency; and / or, the front wall, the bottom wall and the rear wall are all provided with multiple second air outlets, wherein the multiple second air outlets arranged on the front wall are dispersedly arranged along the edge of the front wall, the multiple second air outlets arranged on the bottom wall are dispersedly arranged along the edge of the bottom wall, and the multiple second air outlets arranged on the rear wall are dispersedly arranged along the edge of the rear wall. This setting can increase the air outlet area of ​​the front wall, the bottom wall and the rear wall, so that the outflow path of the external wind at the second air outlet can cover the edges of the front wall, the bottom wall and the rear wall, further increasing the contact area between the external wind and the PCB, thereby ensuring the heat exchange and cooling effect.

[0016] Furthermore, the housing has a left side panel proximate to the fan assembly and a right side panel opposite the left side panel, wherein the side panel is the right side panel. By mounting the electrical control box on the right side panel, the electrical control box is positioned a certain distance from the fan assembly within the housing, thereby reducing interference with the electrical control box during operation of the fan assembly, thereby ensuring operational reliability of the electrical control box.

[0017] Furthermore, the electric control box and the fan assembly are located in a through cavity.

[0018] Furthermore, the electric control box further comprises a box cover, which is openably arranged on the box body and closes the opening of the box body, and the box cover is provided with a ventilation hole communicating with the electronic device cavity and the wiring window.

[0019] The second object of the present invention is to provide an air conditioner to solve the technical problem that the PCB on the front side of the electric control box of the existing air conditioner outdoor unit and the electronic components thereon cannot obtain effective heat dissipation.

[0020] The air conditioner provided by the utility model comprises an air conditioner indoor unit and the above-mentioned air conditioner outdoor unit, wherein the air conditioner indoor unit and the air conditioner outdoor unit are connected via a refrigerant pipeline.

[0021] By arranging the above-mentioned air conditioner outdoor unit in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air conditioner outdoor unit, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] 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.

[0037] Figure 1 A top view of the internal structure of the air conditioner outdoor unit provided in this embodiment; Figure 2 This is a front view of the installation of the electric control box 200 of the air conditioner outdoor unit provided in this embodiment, where the arrows in the figure indicate the direction of air flow; Figure 3 This is a side view of the installation of the electric control box 200 of the air conditioner outdoor unit provided in this embodiment. Figures 1 to 3 As shown, this embodiment provides an air-conditioning outdoor unit, including a casing 100 and an electrical control box 200 and a fan assembly 300 both arranged inside the casing 100. Specifically, the electrical control box 200 includes a box body 210, which is installed on the side panel of the casing 100. The box body 210 and the side panel are connected to form an electronic device cavity 220; the side panel is provided with a wiring window 121 connected to the electronic device cavity 220, and an electrical cover 400 for covering the wiring window 121 is installed on the outside of the side panel, wherein the electrical cover 400 is provided with an air inlet 410 connected to the wiring window 121, and the box body 210 is provided with an air outlet 230 connecting the interior of the casing 100 and the electronic device cavity 220.

[0038] By installing the electric control box 200 on the casing 100 of the air conditioner outdoor unit, a wiring window 121 connected to the electronic device cavity 220 is provided on the side panel, an air inlet 410 connected to the wiring window 121 is provided on the electrical cover 400, and an air outlet 230 connected to the inside of the casing 100 and the electronic device cavity 220 is provided on the box body 210, so that when the air conditioner outdoor unit is running, under the action of the fan assembly 300, the wind outside the casing 100 will enter from the air inlet 410 provided on the electrical cover 400, and further flow into the electronic device cavity 220 of the box body 210 through the wiring window 121 provided on the side panel, thereby dissipating heat for the PCB 240 and electronic components 250 in the electronic device cavity 220; after completing the heat exchange with the above-mentioned components, the air flows to the inside of the casing 100 through the outlet 230 provided in the box body 210, thereby achieving cooling of the components inside the electric control box 200.

[0039] Through the above-mentioned arrangement, the air conditioner outdoor unit forms a heat dissipation channel from the outside of the casing 100 - the electrical cover 400 - the electric control box 200 - the inside of the casing 100 during operation of the air conditioner outdoor unit, thereby being able to bring out the heat inside the electric control box 200, so that the components inside the electric control box 200 are effectively cooled, thereby effectively solving the problems existing in the prior art.

[0040] Please continue to refer to Figure 1 In this embodiment, the casing 100 has a left side panel 110 close to the fan assembly 300 and a right side panel 120 opposite to the left side panel 110, wherein the above-mentioned side panel is the right side panel 120, that is, the electric control box 200 is installed on the right side panel 120, and the box body 210 of the electric control box 200 is connected to the right side panel 120 to form an electronic device cavity 220.

[0041] By installing the electrical control box 200 on the right side panel 120, the electrical control box 200 is kept at a certain distance from the fan assembly 300 inside the casing 100, which can reduce the interference caused by the fan assembly 300 to the electrical control box 200 during operation, thereby ensuring the working reliability of the electrical control box 200.

[0042] Please continue to refer to Figure 1 In this embodiment, the compressor assembly 500 arranged inside the casing 100 is also located in the cavity where the fan assembly 300 and the electrical control box 200 are located. That is, the electrical control box 200, the fan assembly 300 and the compressor assembly 500 are all located in the same cavity inside the casing 100.

[0043] Through the above-mentioned arrangement, the air-conditioning outdoor unit realizes the sealing of the electric control box 200 by utilizing the docking of the box body 210 and the right side panel 120. On the one hand, there is no need to set a wind-proof vertical plate inside the casing 100, which not only effectively reduces the overall size of the air-conditioning outdoor unit, but also is beneficial to the overall refinement and miniaturization design of the air-conditioning outdoor unit, saves materials, and reduces costs, but also can increase the wind cavity area inside the casing 100, which is beneficial to improving the air-conditioning performance; on the other hand, it can also achieve effective insect prevention inside the electric control box 200, avoiding the adverse effects of small insects on the PCB240 and the electronic components 250 arranged thereon.

[0044] It should be noted that, in this embodiment, the “left and right directions” can be Figure 1 and Figure 2 In other words, the left side plate 110 and the right side plate 120 are relative to each other along the direction indicated by the arrows ab; the “front and rear direction” can be represented by Figure 1 and Figure 3 The arrow cd in the figure indicates that the “up and down directions” can be represented by Figure 2 and Figure 3 It is represented by the arrow ef in the figure.

[0045] Figure 4 This is a structural diagram of the electrical cover 400 of the air conditioner outdoor unit provided in this embodiment. Figure 2 , and combined with Figure 4 In this embodiment, the electrical cover 400 may include a cover portion 420. Specifically, the cover portion 420 is opposite to the wiring window 121, and the cover portion 420 is spaced apart from the right side panel 120 to form a first air inlet channel 430; the bottom end of the cover portion 420 is bent toward the right side panel 120 to form a bottom plate portion 440 connected to the right side panel 120, and the air inlet 410 includes a first air inlet 411 opened on the bottom plate portion 440.

[0046] When the air conditioner outdoor unit is running, under the action of the fan assembly 300, a negative pressure is generated inside the housing 100. This negative pressure allows the wind from the external environment to enter from the first air inlet 411 opened on the bottom plate 440, and flow along the first air inlet channel 430 toward the wiring window 121, so as to enter the electronic device cavity 220 through the wiring window 121, thereby achieving heat exchange and cooling of the PCB 240 in the electronic device cavity 220 and the electronic components 250 arranged on the PCB 240; thereafter, the wind after the above-mentioned heat exchange process flows from the air outlet 230 to the inside of the housing 100. Among them, the flow process of the external wind in the first air inlet channel 430 and the outflow process after heat exchange can be referred to. Figure 2 Indicated by the arrow.

[0047] The setting of the above-mentioned electrical cover 400 can not only shield the wiring window 121, preventing impurities from the external environment from entering through the wiring window 121 and causing damage to the PCB 240 and electronic components 250 inside the electrical control box 200, but also form a first air inlet channel 430 together with the right side plate 120. On the one hand, it can guide the external wind so that the external wind can smoothly enter the electronic device cavity 220 through the wiring window 121. On the other hand, it can also use the first air inlet channel 430 to increase the contact time of the external wind with the right side plate 120 before entering the electronic device cavity 220, so that the external wind can achieve a certain degree of cooling of the electronic device cavity 220 through contact heat exchange during the flow of the first air inlet channel 430, thereby ensuring the cooling effect on the electronic device cavity 220.

[0048] Please continue to refer to Figure 2 and Figure 4 In this embodiment, the electrical cover 400 may further include a handle portion 450 and a top plate portion 460. Specifically, the handle portion 450 and the cover portion 420 are arranged at an angle, the top plate portion 460 connects the handle portion 450 and the right side panel 120, and a second air inlet channel 470 connected to the first air inlet channel 430 is formed between the top plate portion 460 and the handle portion 450; the air inlet 410 also includes a second air inlet 412 opened in the handle portion 450.

[0049] During the operation of the air conditioner outdoor unit, part of the external air enters the first air inlet channel 430 from the first air inlet 411 opened on the bottom plate portion 440, and the other part enters the second air inlet channel 470 from the second air inlet 412 opened on the handle portion 450, and further enters the electronic device cavity 220 formed between the box body 210 and the right side plate 120 through the wiring window 121 to perform heat exchange and cooling on the PCB 240 and the electronic components 250 arranged thereon; thereafter, the air that has undergone the heat exchange process, like the air that enters through the first air inlet 411, flows to the interior of the housing 100 through the air outlet 230 opened on the box body 210. The flow process of the external air in the second air inlet channel 470 and the outflow process after heat exchange can be referred to. Figure 2 Indicated by the arrow.

[0050] By providing a handle portion 450 and a top plate portion 460 connecting the handle portion 450 and the right side panel 120 in the electrical cover 400, on the one hand, a force application point is provided for the operator, making it easier for the operator to carry the housing 100. On the other hand, a channel for external wind to enter the electronic device cavity 220 is increased, so that external wind can enter the electronic device cavity 220 as much as possible to achieve heat dissipation for the PCB 240 and the electronic components 250, thereby increasing the flow rate of external wind and improving the cooling effect.

[0051] Specifically, in this embodiment, the handle portion 450 is substantially at a 90° angle to the cover portion 420. This arrangement facilitates the operator to apply a pulling force to the handle portion 450, thereby improving the convenience of carrying the air conditioner outdoor unit.

[0052] Please continue to refer to Figure 2 In this embodiment, the handle portion 450 is tilted downward in a direction away from the side panel. In other words, the handle portion 450 is tilted from top to bottom in a direction from the cover portion 420 toward the external environment.

[0053] By setting the handle portion 450 to the above-mentioned inclined posture, on the one hand, the inclined handle portion 450 can be used to guide the external wind to a certain extent, thereby improving the smoothness of the external wind flowing from the second air inlet 412 to the second air inlet channel 470. On the other hand, an acute-angle space is formed between the handle portion 450 and the cover portion 420, thereby forming a limit when the operator carries the casing 100 through the handle portion 450, reducing the risk of the casing 100 falling off the operator's hands during transportation.

[0054] Please continue to refer to Figure 4 In this embodiment, there are multiple first air inlets 411 , and the multiple first air inlets 411 are dispersedly arranged on the bottom plate portion 440 .

[0055] The arrangement of the above-mentioned multiple first air inlets 411 can not only increase the distribution area of ​​the first air inlets 411 on the bottom plate portion 440, thereby increasing the amount of external wind entering through the first air inlets 411 to improve the cooling efficiency, but also reduce the flow area of ​​the first air inlet 411 under the premise of unchanged air intake volume, so as to prevent external impurities and insects from entering through the first air inlet 411. At the same time, it can also ensure the structural strength of the bottom plate portion 440 and inhibit the deformation of the bottom plate portion 440.

[0056] Please continue to refer to Figure 4 In this embodiment, there are multiple second air inlets 412 , and the multiple second air inlets 412 are dispersedly arranged on the handle portion 450 .

[0057] The arrangement of the above-mentioned multiple second air inlets 412 can not only increase the distribution area of ​​the second air inlets 412 in the handle portion 450, thereby increasing the amount of external wind entering through the second air inlets 412 to improve the cooling efficiency, but also reduce the flow area of ​​the second air inlets 412 under the premise of unchanged air intake volume, so as to prevent external impurities and insects from entering through the second air inlets 412. At the same time, it can also ensure the structural strength of the handle portion 450 and inhibit the deformation of the handle portion 450.

[0058] Furthermore, the positioning of the first and second air inlets 411, 412 directs external air downward at the electrical appliance cover 400, thereby reducing rainwater ingress. Furthermore, the provision of the second air inlet 412 on the handle 450 increases the airflow into the electrical appliance cover 400, preventing insufficient airflow to the bottom plate 440 and supplementing the air flow. Furthermore, the protruding design of the handle 450, closer to the PCB 240, shortens the airflow path and reduces airflow loss compared to a solution in which only the first air inlet 411 is provided on the bottom plate 440.

[0059] Figure 5 A schematic structural diagram of the electric control box 200 of the air conditioner outdoor unit provided in this embodiment; Figure 6 A bottom view of the electric control box 200 of the air conditioner outdoor unit provided in this embodiment; Figure 7 A front view of the electric control box 200 of the air conditioner outdoor unit provided in this embodiment; Figure 8 This is a rear view of the electric control box 200 of the air conditioner outdoor unit provided in this embodiment. Figure 2 , and combined with Figures 5 to 8In this embodiment, the box body 210 includes a mounting wall 211 opposite to the right side plate 120 and multiple side walls arranged around the mounting wall 211, wherein the mounting wall 211 is used to install the PCB 240, and the box body 210 is connected to the right side plate 120 through the multiple side walls; the multiple side walls include a top wall 212 and a bottom wall 213 that are opposite and spaced in the up and down directions, and the air outlet 230 includes a first air outlet 231 opened on the bottom wall 213, and the first air outlet 231 is opposite to the electronic device cavity 220.

[0060] During the operation of the air conditioner outdoor unit, the external air entering through the first air inlet 411 and the second air inlet 412 will flow out through the first air outlet 231 opposite to the electronic device cavity 220 after completing the heat exchange and cooling of the PCB 240 and the electronic components 250 in the electronic device cavity 220.

[0061] By opening the first air outlet 231 on the bottom wall 213 opposite to the electronic device cavity 220, on the one hand, the flow path of the external air in the electronic device cavity 220 can be extended, which not only increases the contact time of the external air with the PCB240 and the electronic components 250, but also allows the external air to fully cover the area where the PCB240 and the electronic components 250 are located during the flow in the electronic device cavity 220, thereby ensuring the adequacy of heat exchange and thereby improving the cooling effect on the electrical control box 200.

[0062] In addition, by setting the first air inlet 411 opposite to the electronic device cavity 220, the air that has undergone heat exchange can be discharged from the first air inlet 411 as quickly as possible, so that the external air that has not undergone heat exchange can be replenished to the electronic device cavity 220 in time, further improving the cooling efficiency.

[0063] Please continue to refer to Figures 5 to 8 In this embodiment, the multiple side walls also include a front wall 214 and a rear wall 215 that are opposite and spaced apart in the front-to-back direction, and the air outlet 230 also includes a second air outlet 232 opened on the front wall 214, the bottom wall 213 and the rear wall 215, wherein the second air outlet 232 is arranged close to the mounting wall 211.

[0064] During the operation of the air conditioner outdoor unit, the external air entering through the first air inlet 411 and the second air inlet 412, after completing the heat exchange and cooling of the PCB240 and the electronic components 250 in the electronic device cavity 220, a part of it flows out through the first air outlet 231 opened in the bottom wall 213, and the other part flows out through the second air outlet 232 opened in the front wall 214, the bottom wall 213 and the rear wall 215.

[0065] By positioning the second air outlet 232 near the mounting wall 211, the second air outlet 232 is closer to the PCB 240. This allows external air entering the electronic device cavity 220 to flow out after sufficient heat exchange with the PCB 240, thereby ensuring a cooling effect on the PCB 240. Furthermore, by providing the second air outlet 232 on the front wall 214, the bottom wall 213, and the rear wall 215, negative pressure is generated at all three locations, allowing air from the electronic device cavity 220 to flow out from these locations. In other words, the external air outflow path surrounds the PCB 240 on three sides, thereby increasing the contact area between the external air and the PCB 240 and further enhancing the cooling effect.

[0066] Please continue to refer to Figure 5 and Figure 6 In this embodiment, there are multiple first air outlets 231 , and the multiple first air outlets 231 are dispersedly arranged on the bottom wall 213 .

[0067] The arrangement of the above-mentioned multiple first air outlets 231 can not only increase the distribution area of ​​the first air outlets 231 on the bottom wall 213, thereby increasing the air outlet volume of the first air outlet 231, so as to improve the efficiency of external wind supplying the electronic device cavity 220, thereby achieving the purpose of improving the cooling efficiency, but also can reduce the flow area of ​​the first air outlet 231 under the premise of unchanged air outlet volume, thereby ensuring the structural strength of the bottom wall 213 and inhibiting the deformation of the bottom wall 213.
