Description

[0001] This application claims priority to Chinese patent application No. 2025213671934, filed on June 30, 2025, entitled "An outdoor unit and an air conditioner", the contents of which shall be construed as incorporated herein by reference. Technical Field

[0002] 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

[0003] 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 connection part 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

[0004] 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.

[0027] This application also provides an air conditioner, including the outdoor unit of the air conditioner described in any of the above embodiments.

[0028] The technical solution provided in this application embodiment is that the control box cover is installed inside the installation cavity at the first connecting port, and a heat dissipation channel is formed between the control box cover and the partition plate. The first connecting port is connected to the installation cavity through the heat dissipation channel. At least one end of the control board near the first connecting port is located in the heat dissipation channel. The heat dissipation channel is configured to form an airflow from the installation cavity to the first connecting port. By concentrating the air flowing from the installation cavity to the first connecting port, the heat dissipation channel ensures that at least almost all of the air passing through the heat dissipation channel passes through the end of the control board near the first connecting port. In this way, the airflow formed by the air flowing from the installation cavity to the first connecting port can better remove the heat on the control board, thus improving the heat dissipation effect of the control board.

[0029] Furthermore, the control box cover includes a first cover and a second cover, with the second cover detachably connected to the first cover. In the left-right direction, the first cover is opposite to the first connecting port, and in the left-right direction, the second cover is opposite to the control board. This allows the control board to be exposed in the installation cavity for maintenance without removing the first cover, by simply removing the second cover.

[0030] Furthermore, the adjacent ends of the second cover and the first cover together form a wiring structure. The wiring structure is configured to carry a first connecting wire for electrical connection with the control board. When assembling the second cover, maintenance personnel first use the portion of the wiring structure located on the first cover or the portion located on the second cover to position the first connecting wire, and then assemble the second cover and the first cover. After the second cover and the first cover are assembled, the portion of the wiring structure located on the second cover and the portion located on the first cover together form a wiring structure. At this time, the first connecting wire is passed through and positioned within the wiring structure. Since the first connecting wire is pre-positioned on the first cover or the second cover before assembling the second cover and the first cover, the process of assembling the second cover and the first cover is simpler for maintenance personnel. Moreover, this solution also facilitates the plugging and unplugging of the first connecting wire on the control board after the second cover is removed.

[0031] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Detailed Implementation

[0036] 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.

[0037] 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.

[0038] 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, rear side, or left 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.

[0039] The control box cover 400 is installed inside the mounting chamber 120 at the first connecting port. A heat dissipation channel 130 is formed between the control box cover 400 and the partition plate 200. The first connecting 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 connecting 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 to the first connecting port. By concentrating the airflow from the mounting chamber 120 to the first connecting 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 connecting port. In this way, the airflow from the mounting chamber 120 to the first connecting port can better remove the heat from the control board 300, thus improving the heat dissipation effect of the control board 300.

[0040] In some examples, the control box cover 400 is a split mechanism, including 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 opening, and in the left-right direction, the second cover 420 is opposite to the control panel. The wiring ports on the control board 300 are opposite each other (so that when wiring needs to be handled, only the second cover 420 needs to be removed to complete the operation, without removing the entire control box cover 00). The rear end of the second cover 420 cooperates with the front end of the first cover 410 and forms a wire passage structure. The wire passage structure is configured to pass through a first connecting wire 500 for electrical connection with the control board 300 (wherein, the control board 300 has an electrical connection part on the side facing away from the middle partition 200, and the first connecting wire 500 is electrically connected to the electrical connection part, which can be a plug terminal).

[0041] 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. In the left-right direction, the first cover 410 is opposite to the first communication port, and in the left-right direction, the second cover 420 is opposite to the control board 300. This allows the control board 300 to be exposed in the mounting chamber 120 for access without removing the first cover 410, by simply removing the second cover 420. 00 is inspected, and since the second cover 420 is located in front of the first cover 410, the second cover 420 is also easy to disassemble and assemble in front of the installation 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, which is configured to carry the first connecting wire 500 for electrical connection with the control board 300. When assembling the second cover 420, maintenance personnel first pass through the part of the wiring structure located in front of the first cover 410 or The first connecting line 500 is positioned at the rear end of the second cover 420, and then the second cover 420 and the first cover 410 are assembled. After the second cover 420 and the first cover 410 are assembled, the rear end of the wire-passing structure of the second cover 420 and the front end of the wire-passing structure of the first cover 410 together form a wire-passing structure. At this time, the first connecting line 500 passes through and is positioned within the wire-passing structure. This solution not only facilitates maintenance personnel to disassemble from the front of the installation chamber 120. Installing the second cover 420 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 makes it easier for 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 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 is also simple for maintenance personnel.

[0042] Alternatively, the wire-passing structure can be located on the first cover 410; or it can be located on the second cover 420, etc. All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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 first wiring bracket 650, and a second cover 420 with a first clearance opening. The first wiring bracket 650 is located on one side of the control board 300 (as shown below) and on the side of the partition 200 facing away from the heat exchange chamber 110. The second cover 420 is installed on the partition 200. The first wiring bracket 650 passes through the first clearance opening. The connecting wires between the compressor and the control board 300, as well as the connecting wires between the fan assembly 610 and the control board 300, all pass through the first clearance opening and are positioned accordingly. On the first wiring rack 650 (the first wiring rack 650 is provided with a cable management structure such as cable clips and cable trays), the first connecting line 500 includes the connecting line between the terminal block and the control board 300, but does not include the connecting line between the compressor and the control board 300, or the connecting line between the fan assembly 610 and the control board 300. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0048] like Figure 5 and Figure 15 As shown, the first cabling frame 650 has a high-voltage cabling area 651 and a low-voltage cabling area 652 arranged sequentially in the vertical direction. The high-voltage cabling area 651 and the low-voltage cabling area 652 are independent of each other and arranged sequentially in the front-back direction. The high-voltage cabling area 651 is equipped with cable clips and cable trays, and the low-voltage cabling area 652 is also equipped with cable clips and cable trays. The high-voltage connection wires arranged on the first cabling frame 650 are located in the high-voltage cabling area 651 and are limited by the cable clips and cable trays in the high-voltage cabling area 651. The low-voltage connection wires arranged on the first cabling frame 650 are located in the low-voltage cabling area 652 and are limited by the cable clips and cable trays in the low-voltage cabling area 652.

[0049] 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, which passes through the wire-passing hole 430. An electrical component 520 is housed in the receiving cavity 440 and is connected to the control board 300. The receiving cavity 440 limits the electrical component 520, making it less likely for the wire body 510 to break when accidentally pulled on the first connecting wire 500. Furthermore, this design simplifies the positioning of the first connecting wire 500, and the portion of the first connecting wire 500 outside the control box cover 400 is neater and less cluttered due to the absence of the electrical component 520. The electrical component 520 includes a magnetic ring.

[0050] In some embodiments, such as Figure 8 and Figure 9As 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 a rounded structure (such as a chamfer) to eliminate sharp edges and prevent scratching or abrasion of the cable 510 at the bends.

[0051] In some embodiments, such as Figures 3 to 5 , Figures 7 to 11 As shown, the rear end of the second cover 420 and the front end of the first cover 410 are both provided with protruding structures 460 that protrude from the partition plate 200 (the two protruding structures 460 are integrally formed with the second cover 420 and the first cover 410 respectively). The two protruding structures 460 are opposite to each other in the front-rear direction and enclose a wire hole 430, a receiving cavity 440 and a wiring channel 450. The area of ​​the opposite side of the two protruding structures 460 is larger, making it easier to arrange the wire hole 430, the receiving cavity 440 and the wiring channel 450. To prevent electromagnetic interference between different first connecting lines 500, the different first connecting lines 500 are arranged in a strong-weak separation manner between the two protruding structures 460; this can be achieved by placing the weak-weak connecting line of the different first connecting lines 500 on the upper side and the strong-weak connecting line of the different first connecting lines 500 on the lower side; or it can be achieved by placing the strong-weak connecting line of the different first connecting lines 500 on the upper side and the weak-weak connecting line of the different first connecting lines 500 on the lower side, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, and will not be elaborated here, and should all fall within the protection scope of this application.

[0052] 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 passage hole 430, a receiving cavity 440, and a wire routing channel 450 (e.g., Figure 8As 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 out of the wire notch and wiring groove, and the electrical component 520 will not come out of 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.

[0053] 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 first wiring bracket 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 its upper end 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 mates with the lower end of the first part 411, and the rear end of the second cover 420 mates with the front end of the second part 412 (the opening of the first cover 410 and...). The openings of the second cover 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 openings of the first cover 410 include 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 openings of the second cover 420 include 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 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.

[0054] 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 control board 300, causing the control board 300 to short circuit or even catch fire.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The arrangement of the first cover 410 and the second cover 420 in this application is not limited to the above embodiments. It can also be that the first cover 410 includes only the first part and does not include the second part. In this case, the first connecting port is located on the upper side of the control board, and the upper end of the second cover 420 and the lower end of the first part of the first cover 410 form a wire-passing structure. Alternatively, the first cover 410 can include only the second part and does not include the first part. In this case, the first connecting port is located on the rear side of the control board, and the rear end of the second cover 420 and the front end of the second part of the first cover 410 form a wire-passing structure. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0059] In other examples, such as Figure 13 and Figure 14 As shown, the electrical control box cover 400 is an integral structure, including an end wall and a closed annular peripheral wall. The closed annular peripheral wall is located between the middle partition 200 and the end wall. The end of the closed annular peripheral wall away from the middle partition 200 is connected to the periphery of the end wall. This solution makes the manufacturing process of the electrical control box cover 400 simpler and the manufacturing cost lower.

[0060] In some embodiments, such as Figure 13 and Figure 14As shown, the first connection port is located on the upper side of the control board 300, and the lower part of the electrical control box cover 400 is provided with a third connection port 421 (i.e., the third connection port 421 is located on the lower part of the side wall and / or bottom wall of the electrical control box cover 40). The heat dissipation channel 130 is connected to the mounting chamber 120 through the third connection port 421. The control board 300 is completely located within the heat dissipation channel 130, and the third connection port 421 is located below the control board 300. In this way, the air in the mounting chamber 120 enters the heat dissipation channel 130 through the third connection port 421. During its upward movement through the heat dissipation channel 130, almost all of it passes through the control board 300, which better removes heat from the control board 300. Then, it enters the heat exchange chamber 110 through the first connection port. This design provides better heat dissipation for the control board 300. Under conditions of high ambient temperature, high compressor operating frequency, and high fan speed, compared with related technical solutions (the two technical solutions 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 in the related technical solutions. Furthermore, the higher the compressor operating frequency and the higher the fan speed, the greater the temperature difference between the maximum temperature of the control board 300 in this application and that in the related technical solutions. In the related technical solutions, when the control board 300 overheats, the outdoor unit needs to reduce the compressor operating frequency to protect the control board 300 from overheating. However, in this application's outdoor unit, the control board 300 does not overheat during operation, therefore the compressor does not need to reduce its operating frequency.

[0061] In some embodiments, such as Figure 13 and Figure 14 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 control board 300, causing the control board 300 to short circuit or even catch fire.

[0062] In some embodiments, such as Figure 13 and Figure 15 As shown, the outdoor unit of the air conditioner also includes: a first wiring rack 650, which is located inside the installation chamber 120 and below the control board 300. The side wall (i.e., the lower end of the peripheral wall) of the electrical control box cover 400 is provided with a first clearance opening 480. The first wiring rack 650 passes through the first clearance opening 480. The connecting wires between the compressor and the control board 300 and the connecting wires between the fan assembly 610 and the control board 300 all pass through the first clearance opening 480 and are positioned on the first wiring rack 650 (the first wiring rack 650 is provided with a wire clip and a cable tray and other cable management structure).

[0063] The first cabling frame 650 has a high-voltage cabling area 651 and a low-voltage cabling area 652 arranged sequentially in the vertical direction. The high-voltage cabling area 651 and the low-voltage cabling area 652 are independent of each other and arranged sequentially in the front-back direction. The high-voltage cabling area 651 is equipped with cable clips and cable trays, and the low-voltage cabling area 652 is also equipped with cable clips and cable trays. The high-voltage connection cables arranged on the first cabling frame 650 are located in the high-voltage cabling area 651 and are limited by the cable clips and cable trays in the high-voltage cabling area 651. The low-voltage connection cables arranged on the first cabling frame 650 are located in the low-voltage cabling area 652 and are limited by the cable clips and cable trays in the low-voltage cabling area 652.

[0064] In some embodiments, such as Figure 13 , Figure 15 and Figure 19 As shown, the first wiring rack 650 includes a main body 653 and a curved extension 654. The main body is located below the control board 300 and passes through the first clearance opening 480. The curved extension 654 is located on the side of the lower end of the control board 300 facing away from the partition plate 200 and is connected to the upper end of the main body 653 adjacent to the control board 300. The connecting lines between the compressor and the control board 300, as well as the connecting lines between the fan assembly 610 and the control board 300 (the connecting lines between the compressor and the control board 300 and the connecting lines between the fan assembly 610 and the control board 300 are the second connecting lines 1000), all cross the curved extension 654 upwards and connect to the control board 300 (see [reference]). Figure 19 In this way, the connecting wires between the compressor and the control board 300, and the connecting wires between the fan assembly 610 and the control board 300 (the connecting wires between the compressor and the control board 300 and the connecting wires between the fan assembly 610 and the control board 300 are the second connecting wires 1000), will bend at the location where they connect to the control board 300 to form an arch bridge 1100 (see...). Figure 19 The connection lines between the compressor and the control board 300, as well as the connection lines between the fan assembly 610 and the control board 300 (the connection lines between the compressor and the control board 300 and the connection lines between the fan assembly 610 and the control board 300 are the second connection lines 1000), will not be attached to the control board 300 and affect the heat dissipation of the control board 300.

[0065] In some embodiments, such as Figure 13 and Figure 14As shown, the side wall (i.e., the lower end of the peripheral wall) of the electrical control box cover 400 is also provided with a second clearance opening 490. The second clearance opening 490 is configured to allow the refrigerant heat exchange pipe 810 to pass through. The refrigerant heat exchange pipe 810 is mounted on the control board 300 through a heat sink. The heat sink is used to increase the heat exchange efficiency between the refrigerant heat exchange pipe 810 and the control board 300. During the process of the refrigerant flowing through the refrigerant heat exchange pipe 810, it carries away the heat on the control board 300 and cools down the control board 300.

[0066] In some embodiments, the outdoor unit of the air conditioner further includes a terminal block 820 with a fixed terminal block, and one end of the wiring structure away from the partition 200 is connected to the terminal block of the terminal block 820. Alternatively, the terminal block and the terminal block 820 may be an integral structure.

[0067] In other embodiments, such as Figures 13 to 18 As shown, the outdoor unit of the air conditioner also includes: a terminal block 820 arranged in the front-to-back direction, the terminal block 820 being located on one side of the electrical control box cover 400 away from the middle partition 200 and spaced apart from the electrical control box cover 400; and a second wiring rack 830 arranged in the left-to-right direction, the second wiring rack 830 being located between the electrical control box cover 400 and the terminal block 820 and connecting the electrical control box cover 400 and the terminal block 820, the end wall being provided with a fourth connecting port 470, the fourth connecting port 470 being correspondingly provided with the second wiring rack 830, and the first connecting wire 900 passing through the fourth connecting port 470 and being provided on the second wiring rack 830. The first connecting line 900 includes the connecting line between the control board 300 and the terminal board 820, but the first connecting line 900 does not include the connecting line between the compressor and the control board 300 and the connecting line between the fan assembly 610 and the control board 300 (the connecting line between the compressor and the control board 300 and the connecting line between the fan assembly 610 and the control board 300 are the second connecting line 1000), and the first connecting line 900 can also be configured to separate strong and weak current on the second wiring frame 830.

[0068] Among them, such as Figures 13 to 18As shown, the second wiring rack 830 includes a connecting part 831 and a wiring part 832. The left end of the second wiring rack 830 is detachably fixed to the end wall of the electrical control box cover 400 via the connecting part 831 (e.g., by screw fixing, snap-fit ​​fixing and / or plug-in fixing). The right end of the second wiring rack 830 is connected to the front end of the terminal board 820 (e.g., by hook connection). The wiring part 832 is located on the front side of the second wiring rack 830 and extends backward at an angle from left to right. The left end of the wiring part 832 is connected to the connecting part 831. The front side of the wiring part 832 is provided with a wire clip and a wiring groove. The wiring groove is opposite to and connected to the fourth connecting port 470 in the left and right directions. The first connecting wire 900 is positioned by the wire clip and the wiring groove and passes through the fourth connecting port 470. This solution facilitates the installation and removal of the first connecting wire 900 from the front side. The wire clip includes a guide section, which guides the first connecting line 900 into the wire clip. The guide section can be a guide slope or a guide curved surface, etc. Figure 13 and Figure 14 As shown, the second wiring frame 830 is installed at the fourth connection port 470 and is connected to the fourth connection port 470 in the left and right directions through the wiring groove.

[0069] Alternatively, the control box cover 400 can be a single integrated structure, including an end wall and an open annular peripheral wall. The open annular peripheral wall is located between the partition plate 200 and the end wall. The end of the open annular peripheral wall away from the partition plate 200 is connected to the periphery of the end wall. The heat dissipation channel 130 is connected to the installation chamber 120 through the open end of the open annular peripheral wall. This solution is suitable for some occasions where there are no special insect prevention requirements and only heat dissipation is required. The open end of the open annular peripheral wall is located at the lower part of the open annular peripheral wall. The first connecting port is located inside the upper part of the control box cover 400. The first clearance port 480 and the second clearance port 490 are part of the open end of the open annular peripheral wall, meaning that the first wiring bracket 650 and the refrigerant heat exchange tube 810 both pass through the open end of the open annular peripheral wall. This solution can also achieve the purpose of this application, and its intent does not depart from the design concept of this utility model. It will not be elaborated further here and should also fall within the protection scope of this application.

[0070] 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.

[0071] This air conditioner possesses all the advantages of the outdoor unit provided in any of the above embodiments, which will not be repeated here.

[0072] 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.
