Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air conditioning equipment technology, specifically referring to an outdoor air conditioning unit and an air conditioner. Background Technology

[0002] An air conditioner outdoor unit, such as Figure 1 As shown, the device includes a housing, a partition plate with a first communication port 20, a control board 30, an electrical control mounting bracket, an electrical control mounting plate with a second communication port 40, and a fan assembly. The partition plate is erected inside the housing and divides the interior of the housing into a heat exchange chamber 11 and an installation chamber 12. The heat exchange chamber 11 is located on the left side of the installation chamber 12. The fan assembly is located inside the heat exchange chamber 11. The electrical control mounting bracket is mounted on the partition plate inside the installation chamber 12. The first communication port 20 and the second communication port 40 are opposite each other. The control board 30 is erected along the front-to-back direction and is located on the side of the electrical control mounting frame facing away from the central partition. The control board 30 is also located below the second connecting port 40, and both the control board 30 and the second connecting port 40 are exposed within the mounting chamber 12. When the fan assembly is running, a wind beam is formed at the second connecting port 40, flowing from the mounting chamber 12 through the second connecting port 40 and the first connecting port 20 into the heat exchange chamber 11. The wind beam carries away the heat from the control board 30, thus achieving heat dissipation and cooling of the control board 30. How to better improve the heat dissipation effect of the control board 30 has always been a technical problem that those skilled in the art have been committed to solving. Utility Model Content

[0003] Analysis revealed that because both the control board and the second connection port are exposed within the installation chamber, when the fan assembly is running, the air above, behind, below, and in front of the second connection port on the right side of the installation chamber all flows towards the second connection port. Only a portion of this air flowing towards the second connection port passes through the control board, carrying away the heat on it; the rest does not pass through the control board and cannot carry away the heat. Therefore, the heat dissipation effect of the control board in this design is poor.

[0004] This application provides an air conditioner outdoor unit, including: a housing; a partition plate, erected inside the housing and separating the interior of the housing into a heat exchange chamber and an installation chamber, the heat exchange chamber and the installation chamber being arranged sequentially in a left-right direction, the partition plate having a first connecting opening; a control board, the protruding structure being configured to position a wire and an electrical component, a first connecting line electrically connected to the control board including the wire and the electrical component, the electrical component being disposed on the wire; and a first cover, installed inside the installation chamber at the first connecting opening, the side of the first cover facing the control board having an opening, the space between the partition plate and the first cover communicating with the opening and the first connecting opening, the opening wall having a protruding structure protruding away from the partition plate, the protruding structure being configured to position the wire and the electrical component.

[0005] In some exemplary embodiments, the side of the protruding structure facing the control panel is provided with a wire passage notch and a receiving groove, the wire passes through the wire passage notch, and the electrical component is placed in the receiving groove.

[0006] In some exemplary embodiments, the electrical device includes a magnetic ring.

[0007] In some exemplary embodiments, the side of the protruding structure facing the control panel is further provided with a wiring groove, and the wire is also passed through the wiring groove.

[0008] In some exemplary embodiments, the side of the protruding structure facing the control panel is provided with a rib, the rib is provided with the wire passing notch, the receiving groove is formed inside the area enclosed by the rib, and the wiring groove is formed between adjacent ribs.

[0009] In some exemplary embodiments, at least one of the wire guide notch and the wire routing groove is provided with a buckle to prevent the wire from coming out.

[0010] In some exemplary embodiments, the inner side of the wiring groove is provided with a mating rib, and the electrical component is interference-fitted with the mating rib.

[0011] In some exemplary embodiments, the first communication port is located on the upper side of the control panel, the first cover includes a first part and a second part, the first communication port is opposite to the first part in the left-right direction, the upper end of the second part is connected to the rear end of the first part, the control panel is located in front of the second part and below the first part, the lower part of the first part is provided with a downward-facing first opening, the front part of the second part is provided with a forward-facing second opening, the opening includes the first opening and the second opening, the wall of the second opening away from the partition plate is provided with a protruding structure protruding away from the partition plate, and the first connecting line is positioned in front of the protruding structure.

[0012] In some exemplary embodiments, the outdoor unit of the air conditioner further includes: a second cover located in front of the second part and below the first part in the mounting cavity, and detachably mounted on the control panel, wherein a third connection port is provided at one end of the second cover away from the first connection port, and the space between the partition plate and the second cover connects the opening and the third connection port.

[0013] This application also provides an air conditioner, including the outdoor unit of the air conditioner described in any of the above embodiments.

[0014] The technical solution provided in this application embodiment involves a first cover installed inside the mounting cavity at the first connecting port. An opening is provided on the side of the first cover facing the control board. The space between the partition and the first cover connects the opening and the first connecting port. In this solution, the opening of the first cover faces the control board. Thus, when the first connecting port applies negative pressure to the space between the partition and the first cover, the opening of the first cover can better draw air from the control board, resulting in better heat dissipation for the control board. When the first connecting port applies positive pressure to the space between the partition and the first cover, the air blown out of the opening of the first cover directly blows onto the control board, further improving heat dissipation for the control board. Furthermore, the wires and electrical components of the first connecting line electrically connected to the control board are positioned on a protruding structure. This makes the portion of the first connecting line outside the first cover cleaner and less cluttered because it lacks electrical components.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0033] Analysis and research have found that: Figure 1 As shown, since both the control board 30 and the second connection port 40 are exposed within the mounting chamber 12, when the fan assembly is running, the air above, behind, below, and in front of the second connection port 40 on the right side of the mounting chamber 12 all flows toward the second connection port 40. Only a portion of this air flowing toward the second connection port 40 passes through the control board 30, carrying away the heat from the control board 30. The other portion does not pass through the control board 30 and cannot carry away the heat from the control board 30. Therefore, the heat dissipation effect of the control board 30 in this scheme is poor.

[0034] The air conditioner outdoor unit provided in this application embodiment, such as Figures 2 to 12As shown, it includes: a shell; a partition 200, which is erected inside the shell and divides the interior of the shell into a heat exchange chamber 110 and an installation chamber 120, which are arranged sequentially in the left-right direction, and the partition 200 is provided with a first communication port; and a control plate 300, which is erected inside the installation chamber 120 and arranged in the front-back direction, and the first communication port is located on one side of the control plate 300 (such as the upper side, the rear side, or the lower side). The control box cover 400 is installed inside the mounting chamber 120 at the first connection port. A heat dissipation channel 130 is formed between the control box cover 400 and the partition plate 200. The first connection port is connected to the mounting chamber 120 through the heat dissipation channel 130. At least one end of the control board 300 adjacent to the first connection port is located in the heat dissipation channel 130. The heat dissipation channel 130 is configured to form an airflow from the mounting chamber 120 through the heat dissipation channel 130 to the first connection port. The control box cover 400 includes a first cover 410 and a second cover 420. The second cover 420 is located in front of the first cover 410 and is detachably connected to the first cover 410 (the first cover 410 and the second cover 420 have openings at opposite positions, the openings connecting the space between the first cover 410 and the partition 200 and the space between the second cover 420 and the partition 200). In the left-right direction, the first cover 410 is opposite to the first connecting port, and in the left-right direction, the second cover 420 is opposite to the control board 300. The rear end of the second cover 420 cooperates with the front end of the first cover 410 and forms a wire-passing structure. The wire-passing structure is configured to pass through a first connecting wire 500 for electrical connection with the control board 300 (wherein, the side of the control board 300 facing away from the partition 200 has an electrical connection part, and the first connecting wire 500 is electrically connected to the electrical connection part, which can be a plug-in terminal).

[0035] The control box cover 400 is installed inside the mounting chamber 120 at the first connection port. A heat dissipation channel 130 is formed between the control box cover 400 and the partition plate 200. The first connection port is connected to the mounting chamber 120 through the heat dissipation channel 130. At least one end of the control board 300 adjacent to the first connection port is located within the heat dissipation channel 130. The heat dissipation channel 130 is configured to form an airflow from the mounting chamber 120 through the heat dissipation channel 130 to the first connection port. By concentrating the airflow from the mounting chamber 120 to the first connection port, the heat dissipation channel 130 ensures that at least almost all of the air passing through the heat dissipation channel 130 passes through the end of the control board 300 adjacent to the first connection port. The airflow from the opening effectively removes heat from the control board 300, resulting in better heat dissipation. Furthermore, the control box cover 400 includes a first cover 410 and a second cover 420. The second cover 420 is located in front of the first cover 410 and detachably connected to it. In the left-right direction, the first cover 410 faces the first connecting opening, and in the left-right direction, the second cover 420 faces the control board 300. This allows for maintenance of the control board 300 within the mounting chamber 120 by removing only the second cover 420 without removing the first cover 410. Moreover, because the second cover 420 is located within the first cover 410... The second cover 420 is also easily disassembled and assembled from the front side of the mounting chamber 120. Furthermore, the rear end of the second cover 420 mates with the front end of the first cover 410 to form a wiring structure. This wiring structure is configured to allow the passage of a first connecting wire 500 for electrical connection with the control board 300. When assembling the second cover 420, maintenance personnel first position the first connecting wire 500 using either the portion of the wiring structure located at the front end of the first cover 410 or the portion located at the rear end of the second cover 420, and then assemble the second cover 420 and the first cover 410. After the second cover 420 and the first cover 410 are assembled, the portion of the wiring structure located at the rear end of the second cover 420 mates with the portion of the wiring structure... The portion at the front end of the first cover 410 forms a wire-passing structure. At this time, the first connecting wire 500 passes through and is positioned within the wire-passing structure. This design not only facilitates the maintenance personnel to disassemble and assemble the second cover 420 from the front side of the installation chamber 120, but also facilitates the insertion and removal of the first connecting wire 500 on the control board 300 after the second cover 420 is removed. It also facilitates the maintenance personnel to position the first connecting wire 500 from the front side of the installation chamber 120 at the front end of the first cover 410 or the rear end of the second cover 420. Since the first connecting wire 500 is positioned and installed at the front end of the first cover 410 or the rear end of the second cover 420, the process of assembling the second cover 420 and the first cover 410 by the maintenance personnel is also simple.

[0036] In some embodiments, such as Figure 2 and Figure 4As shown, the outdoor unit of the air conditioner also includes a fan assembly 610 and a heat exchanger assembly. Both the fan assembly 610 and the heat exchanger assembly are located within the heat exchange chamber 110, with the fan assembly 610 positioned in front of the heat exchanger assembly. A first connecting port is located between the fan blades of the fan assembly 610 and the heat exchanger assembly. When the fan assembly 610 is running, an airflow is formed at the first connecting port, flowing from the heat dissipation channel 130 through the first connecting port into the heat exchange chamber 110. An airflow from back to front is formed within the heat exchange chamber 110. The wall of the mounting chamber 120 is provided with an air inlet, which connects to the outside environment and the mounting chamber 120. Outside air is supplied into the mounting chamber 120 through the air inlet.

[0037] In some embodiments, such as Figure 2 and Figure 4 As shown, the outdoor unit of the air conditioner also includes a rain cover 620. The rain cover 620 is located inside the heat exchange chamber 110 and covers the first connection port. The rain cover 620 is used to prevent rainwater that has entered the heat exchange chamber 110 from splashing onto the first connection port. In this way, the splashed rainwater will not reach the control board 300 through the first connection port and cause the control board 300 to short-circuit and be damaged by water.

[0038] In some embodiments, the outdoor unit of the air conditioner also includes a terminal block (not shown in the figure), the heat exchange chamber 110 is located on the left side of the mounting chamber 120, the terminal block is located on the right rear side of the first cover 410, the second cover 420 is located on the front side of the terminal block in the front-rear direction, and the first connecting line 500 includes a connecting line between the terminal block and the control board 300.

[0039] In some embodiments, the outdoor unit of the air conditioner also includes a compressor (not shown), which is located in the mounting chamber 120 and below the electrical control box cover 400.

[0040] Alternatively, the first connecting line 500 may also include a connecting line between the compressor and the control board 300, and a connecting line between the fan assembly 610 and the control board 300 (not shown in this schematic diagram); or it may be, as... Figures 2 to 7As shown, the outdoor unit of the air conditioner also includes a wiring rack 650. The second cover 420 is provided with a clearance opening. The wiring rack 650 is located on one side of the control board 300 and on the side of the partition 200 facing away from the heat exchange chamber 110. The second cover 420 covers the partition 200. The wiring rack 650 passes through the clearance opening. The connecting wires between the compressor and the control board 300 and between the fan assembly 610 and the control board 300 all pass through the clearance opening and are positioned on the wiring rack 650 (the wiring rack 650 is provided with wire clips and cable trays, etc.). At this time, the first connecting wire 500 includes the connecting wire between the terminal board and the control board 300, but does not include the connecting wire between the compressor and the control board 300 and the connecting wire between the fan assembly 610 and the control board 300. All of the above can achieve the purpose of this application. Its purpose has not departed from the design concept of this utility model, and will not be elaborated here. All of them should fall within the protection scope of this application.

[0041] In some embodiments, such as Figures 7 to 11 As shown, the wire-passing structure includes a wire-passing hole 430 and a receiving cavity 440. The first connecting wire 500 includes a wire body 510 and an electrical component 520 disposed on the wire body 510. The wire body 510 passes through the wire-passing hole 430, and the electrical component 520 is placed in the receiving cavity 440. The receiving cavity 440 limits the electrical component 520, thus making it less likely for the wire body 510 to break when it is accidentally pulled when it is inserted into the control board 300. Moreover, the positioning method of the first connecting wire 500 is also simple, and the part of the first connecting wire 500 outside the control box cover 400 is neater and less cluttered because it does not contain the electrical component 520. The electrical component 520 includes a magnetic ring.

[0042] In some embodiments, such as Figure 8 and Figure 9 As shown, the wiring structure also includes a wiring channel 450, and the cable 510 is also inserted within the wiring channel 450. The bends in the wiring channel 450 are transitioned by an arc structure (such as a chamfer) to eliminate sharp edges and prevent the bends in the wiring channel 450 from scratching or abrading the cable 510.

[0043] In some embodiments, such as Figures 3 to 5 , Figures 7 to 11 As shown, both the rear end of the second cover 420 and the front end of the first cover 410 are provided with protruding structures 460 that protrude from the central partition 200. The two protruding structures 460 are opposite each other in the front-rear direction and enclose a wire hole 430, a receiving cavity 440, and a wiring channel 450. The areas on the opposite sides of the two protruding structures 460 are larger, making it easier to arrange the wire hole 430, the receiving cavity 440, and the wiring channel 450. In order to prevent electromagnetic interference between different first connecting lines 500, the different first connecting lines 500 are also arranged to separate strong and weak currents between the two protruding structures 460.

[0044] In some embodiments, such as Figures 8 to 11 As shown, the protruding structure 460 of the first cover 410 is provided with a forward-protruding rib 461. The protruding structure 460 of the first cover 410, together with the protruding structure 460 of the second cover 420 through the rib 461, forms a wire hole 430, a receiving cavity 440, and a wire routing channel 450 (e.g., Figure 8 As shown, a wire-passing notch is formed on the rib 461, a receiving groove is formed inside the area enclosed by the rib 461, a wire-passing groove is formed between adjacent ribs 461, the wire-passing hole 430 includes the wire-passing notch, the receiving cavity 440 includes the receiving groove, and the wire-passing channel 450 includes the wire-passing groove. This scheme has a simple structure and is easy to implement. The wire notch and wiring groove can be equipped with buckles to prevent the wire 510 from coming out. The inner side of the receiving groove can be equipped with mating ribs. The mating ribs are interference-fitted with the electrical component 520 on both sides (so that the electrical component 520 is positioned between the mating ribs on both sides). In this way, after the first connecting wire 500 is installed on the mating part of the first cover 410, it will not come off the mating part of the first cover 410 (that is, the wire 510 will not come off the wire notch and wiring groove, and the electrical component 520 will not come off the receiving groove), which is more conducive to the subsequent installation of the second cover 420. The interference fit between the electrical component 520 and the mating rib is a line contact. Compared with the interference fit between the electrical component 520 and the inner circumferential surface of the receiving groove, the installation and removal speed of the electrical component 520 in the receiving groove is faster.

[0045] In some embodiments, such as Figures 4 to 7As shown, the first connecting port is located on the upper side of the control board 300, the wiring rack 650 is located on the lower side of the control board 300, and the first cover 410 includes a first part 411 and a second part 412. In the left-right direction, the first connecting port is opposite to the first part 411. The second part 412 is located on the rear side of the control board 300, and the upper end of the second part 412 is connected to the rear end of the first part 411. The second cover 420 is located in front of the second part 412 and below the first part 411. The upper end of the second cover 420 is engaged with the lower end of the first part 411, and the rear end of the second cover 420 is engaged with the front end of the second part 412 (the opening of the first cover 410 is connected to the first part 411). The openings of the two covers 420 are connected. The lower part of the first part 411 has a downward-facing first opening, and the front part of the second part 412 has a forward-facing second opening. The opening of the first cover 410 includes the first opening and the second opening. The upper part of the second cover 420 has an upward-facing third opening, and the rear part of the second cover 420 has a rearward-facing fourth opening. The opening of the second cover 420 includes the third opening and the fourth opening. Two protruding structures 460 are located at the rear end of the second cover 420 and the front end of the second part 412, respectively. The lower end of the second cover 420 has a third connecting port 421, and the heat dissipation channel 130 is connected to the mounting chamber 120 through the third connecting port 421. In this design, the control board 300 is entirely located within the heat dissipation channel 130, and the third connecting port 421 is located below the control board 300. This allows air from the mounting chamber 120 to enter the heat dissipation channel 130 through the third connecting port 421. As the air travels upwards through the heat dissipation channel 130, almost all of it passes through the control board 300, effectively carrying away heat from the control board 300. The air then enters the heat exchange chamber 110 through the first connecting port. This design results in better heat dissipation for the control board 300. Figure 1 and Figure 12 As shown, under conditions of high ambient temperature, high compressor operating frequency, and high fan speed, compared with related technologies (the two technologies operate under the same conditions and parameters, with the only structural difference being the addition of an electrical control box cover 400 in this application), the maximum temperature of the control board 300 in this application is at least 20 degrees Celsius lower than that of the control board in the related technologies. Furthermore, the higher the compressor operating frequency and the higher the fan assembly 610 speed, the greater the temperature difference between the maximum temperature of the control board 300 in this application and that in the related technologies. In the related technologies, when the control board of the outdoor unit overheats, the compressor operating frequency needs to be reduced to protect the control board from overheating. However, in the outdoor unit of this application, since the control board 300 does not overheat during operation, the compressor does not need to reduce its operating frequency.

[0046] In some embodiments, such as Figure 3 , Figure 5 , Figure 10 and Figure 11 As shown, the third connecting port 421 is a grille hole, and the width of the grille hole is no more than 3mm. This can also prevent crawlers from entering the heat dissipation channel 130 through the third connecting port 421 and crawling onto the circuit board, causing the circuit board to short circuit or even catch fire.

[0047] In some embodiments, such as Figures 4 to 7 As shown, the outdoor unit of the air conditioner also includes: an electrical control mounting bracket 700 with a second communication port 710, which is disposed on the middle partition 200 in the mounting chamber 120; an electrical control box cover 400 is mounted on the side of the electrical control mounting bracket 700 facing away from the middle partition 200 and together with the electrical control mounting bracket 700 forms a heat dissipation channel 130; the first communication port is connected to the heat dissipation channel 130 through the second communication port 710.

[0048] In some embodiments, such as Figure 11 As shown, the first cover 410 and the second cover 420 are independent of each other. The first cover 410 is provided with a first hook-on part, a second hook-on mating part, and a first screw-on part. The electrical control mounting bracket 700 is provided with a first hook-on mating part, a first screw-on mating part, and a second screw-on mating part. The first hook-on part and the first hook-on mating part are hooked together, and the first screw-on part and the first screw-on mating part are connected by a threaded connector, so that the first cover 410 and the electrical control mounting bracket 700 are fixedly connected together. The second cover 420 is provided with a second hook-on part and a second screw-on part. The second hook-on part and the second hook-on mating part are hooked together, and the second screw-on part and the second screw-on mating part are connected by a threaded connector, so that the second cover 420 is assembled with the first cover 410 and the electrical control mounting bracket 700. This scheme has a simple structure and is easy to implement.

[0049] In other embodiments, such as Figure 10 As shown, the first cover 410 and the second cover 420 are hinged together, with the first cover 410 located at the snap-fit ​​part and the second cover 420 having a snap-fit ​​part. Rotating the second cover 420 toward the first cover 410 causes the snap-fit ​​part and the snap-fit ​​part to engage, assembling the first cover 410 and the second cover 420 together. At this time, the second cover 420 covers the control plate 300 within the mounting chamber 120. Disengaging the snap-fit ​​part and the snap-fit ​​part, and rotating the second cover 420 away from the first cover 410, allows the second cover 420 to move away from the control plate 300, exposing the control plate 300 within the mounting chamber 120.

[0050] The air conditioner provided in this application embodiment (not shown in the figure) includes the air conditioner outdoor unit described in any of the above embodiments.

[0051] This air conditioner possesses all the advantages of the outdoor unit provided in any of the above embodiments, which will not be repeated here.

[0052] In summary, the technical solution provided in this application embodiment involves an electrical control box cover installed inside the mounting cavity at the first connecting port. A heat dissipation channel is formed between the electrical control box cover and the partition plate. The first connecting port is connected to the mounting cavity through the heat dissipation channel. At least one end of the control board adjacent to the first connecting port is located within the heat dissipation channel. The heat dissipation channel is configured to form an airflow from the mounting cavity through the heat dissipation channel to the first connecting port. By concentrating the air flowing from the mounting cavity to the first connecting port, the heat dissipation channel ensures that at least substantially all of the air passing through the heat dissipation channel passes through the end of the control board adjacent to the first connecting port. This airflow from the mounting chamber to the first connecting port effectively removes heat from the control board, resulting in better heat dissipation. Furthermore, the control box cover includes a first cover and a second cover. The second cover is located in front of the first cover and detachably connected to it. The first cover faces the first connecting port in the left-right direction, and the second cover faces the control board in the left-right direction. This allows for maintenance of the control board within the mounting chamber by removing only the second cover without removing the first cover. Moreover, because the second cover… The first cover is located on the front side of the first cover, and the second cover is also easily assembled and disassembled on the front side of the installation chamber. Furthermore, the rear end of the second cover mates with the front end of the first cover, forming a wiring passage structure. This structure is designed to carry a first connecting wire for electrical connection with the control board. When assembling the second cover, maintenance personnel first locate the first connecting wire using either the portion of the wiring passage structure located at the front end of the first cover or the portion located at the rear end of the second cover, then assemble the second and first covers. After the second and first covers are assembled, the portion of the wiring passage structure located at the rear end of the second cover... The portion of the wiring structure located at the front end of the first cover forms the wiring structure. At this time, the first connecting wire is threaded through and positioned within the wiring structure. This design not only facilitates the installation and removal of the second cover by maintenance personnel from the front side of the installation chamber, but also makes it convenient for the first connecting wire to be plugged and unplugged on the control panel after the second cover is removed. It also makes it convenient for maintenance personnel to position the first connecting wire from the front side of the installation chamber at the front end of the first cover or the rear end of the second cover. Since the first connecting wire is positioned at the front end of the first cover or the rear end of the second cover, the process of assembling the second cover and the first cover by maintenance personnel is simpler.
