The control panel 30 is also located below the second communication port 40, and both the control panel 30 and the second communication port 40 are exposed within the mounting chamber 12. When the fan assembly is in operation, a wind beam is formed at the second communication port 40, flowing from the mounting chamber 12 through the second communication port 40 and the first communication port 20 to the heat exchange chamber 11. This wind beam removes heat from the control panel 30, thereby dissipating heat and cooling the control panel 30.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any manner.

[0033] The analysis and research found that: Figure 1 As shown, since the control board 30 and the second connecting port 40 are both exposed in the installation chamber 12, when the fan assembly is running, the air above the right side, behind the right side, below the right side and in front of the right side of the second connecting port 40 in the installation chamber 12 all flows toward the second connecting port 40. Only a part of the air flowing toward the second connecting port 40 passes through the control board 30 and takes away the heat from the control board 30. The other part does not pass through the control board 30 and cannot take away the heat from the control board 30. Therefore, the heat dissipation effect of the control board 30 in this solution is poor.

[0034] The air conditioner outdoor unit provided in the embodiment of the present application is as follows Figures 2 to 12As shown, it includes: a shell; a middle partition plate 200, which is vertically arranged in the shell and divides the interior of the shell into a heat exchange chamber 110 and an installation chamber 120, the heat exchange chamber 110 and the installation chamber 120 are arranged in sequence in the left and right directions, and the middle partition plate 200 is provided with a first communication port; a control board 300, which is vertically arranged in the installation chamber 120 and arranged in the front-to-back direction, and the first communication port is located on one side of the control board 300 (such as the upper side, the rear side or the lower side, etc.); And the electric control box cover 400, the electric control box cover 400 is installed at the first communication port in the installation chamber 120, a heat dissipation channel 130 is formed between the electric control box cover 400 and the middle partition 200, the first communication port is connected to the installation chamber 120 through the heat dissipation channel 130, at least one end of the control board 300 adjacent to the first communication port is located in the heat dissipation channel 130, and the heat dissipation channel 130 is configured to form an air beam flowing from the installation chamber 120 through the heat dissipation channel 130 to the first communication port. Among them, the electric control box cover 400 includes a first cover body 410 and a second cover body 420, the second cover body 420 is located on the front side of the first cover body 410 and is detachably connected to the first cover body 410 (the first cover body 410 and the second cover body 420 are opposite to each other at the positions, and the opening connects the space between the first cover body 410 and the middle partition 200 and the space between the second cover body 420 and the middle partition 200), the first cover body 410 is opposite to the first connecting port in the left and right directions, and the second cover body 420 is opposite to the control board 300 in the left and right directions, and the rear end of the second cover body 420 is matched with the front end of the first cover body 410 and enclosed to form a wire passing structure, the wire passing structure is configured to pass through a first connecting wire 500 for electrical connection to the control board 300 (wherein, an electrical connecting part is provided on the side of the control board 300 facing away from the middle partition 200, the first connecting wire 500 is electrically connected to the electrical connecting part, and the electrical connecting part can be a plug-in terminal).

[0035] The electric control box cover 400 is installed at the first communication port in the installation chamber 120. A heat dissipation channel 130 is formed between the electric control box cover 400 and the middle partition plate 200. The first communication port is connected to the installation chamber 120 through the heat dissipation channel 130. At least one end of the control board 300 adjacent to the first communication port is located in the heat dissipation channel 130. The heat dissipation channel 130 is configured to form a wind beam flowing from the installation chamber 120 through the heat dissipation channel 130 to the first communication port. The heat dissipation channel 130 gathers the air flowing from the installation chamber 120 to the first communication port, so that at least substantially all of the air passing through the heat dissipation channel 130 passes through one end of the control board 300 adjacent to the first communication port, thereby The air flow formed by the air from the opening can better take away the heat on the control board 300, so the heat dissipation effect of the control board 300 is better. In addition, the electric control box cover 400 includes a first cover body 410 and a second cover body 420. The second cover body 420 is located at the front side of the first cover body 410 and is detachably connected to the first cover body 410. In the left and right directions, the first cover body 410 is opposite to the first communication port, and in the left and right directions, the second cover body 420 is opposite to the control board 300. In this way, without removing the first cover body 410, only the second cover body 420 is removed, and the control board 300 can be exposed in the installation chamber 120 for inspection and maintenance of the control board 300. Moreover, since the second cover body 420 is located at the first cover body 4 10, the second cover body 420 is also easy to disassemble and assemble at the front side of the installation chamber 120; furthermore, the rear end of the second cover body 420 cooperates with the front end of the first cover body 410 and encloses a wire-passing structure, and the wire-passing structure is configured to pass through the first connecting wire 500 for electrical connection with the control board 300. When assembling the second cover body 420, the maintenance personnel first locate the first connecting wire 500 through the part of the wire-passing structure located at the front end of the first cover body 410 or the part located at the rear end of the second cover body 420, and then assemble the second cover body 420 and the first cover body 410. After the second cover body 420 and the first cover body 410 are assembled, the part of the wire-passing structure located at the rear end of the second cover body 420 is aligned with the wire-passing structure The part located at the front end of the first cover body 410 is enclosed into a wire-passing structure. At this time, the first connecting line 500 is passed through and positioned in the wire-passing structure. This solution not only makes it convenient for maintenance personnel to disassemble and assemble the second cover body 420 from the front side of the installation chamber 120, but also makes it convenient for the first connecting line 500 to be plugged in and out of the control board 300 after removing the second cover body 420. It also makes it convenient for maintenance personnel to position the first connecting line 500 at the front end of the first cover body 410 or the rear end of the second cover body 420 from the front side of the installation chamber 120. Since the first connecting line 500 is positioned and installed at the front end of the first cover body 410 or the rear end of the second cover body 420, the process of maintenance personnel assembling the second cover body 420 and the first cover body 410 is also simple.

[0036] In some embodiments, as Figure 2 and Figure 4As shown, the air conditioner outdoor unit also includes a fan assembly 610 and a heat exchanger assembly. Both the fan assembly 610 and the heat exchanger assembly are arranged in the heat exchange chamber 110, and the fan assembly 610 is located on the front side of the heat exchanger assembly. The 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 in operation, a wind beam is formed at the first connecting port, flowing from the heat dissipation channel 130 through the first connecting port to the heat exchange chamber 110, and a wind beam is formed in the heat exchange chamber 110 that flows from the back to the front. The wall of the installation chamber 120 is provided with an air inlet, which connects the outside world and the installation chamber 120, and the outside air is replenished into the installation chamber 120 through the air inlet.

[0037] In some embodiments, as Figure 2 and Figure 4 As shown, the air conditioner outdoor unit also includes a rain cover 620, which is located in the heat exchange chamber 110 and covers the first connecting port. The rain cover 620 is used to prevent rainwater that flows into the heat exchange chamber 110 from splashing to the first connecting port, so that the splashed rainwater will not reach the control panel 300 through the first connecting port and cause the control panel 300 to be damaged by a short circuit due to water.

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

[0039] In some embodiments, the air conditioner outdoor unit further includes a compressor (not shown in the figure), which is disposed in the installation chamber 120 and below the electric control box cover 400 .

[0040] It can be that the first connecting line 500 also includes 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 scheme); or it can be, Figures 2 to 7As shown, the air-conditioning outdoor unit also includes a wiring rack 650, and the second cover body 420 is provided with an avoidance opening. The wiring rack 650 is located on one side of the control board 300 and is arranged on the side of the middle partition 200 facing away from the heat exchange chamber 110. The second cover body 420 is covered on the middle partition 200, and the wiring rack 650 is passed through the avoidance opening. 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 all passed through the avoidance opening and positioned on the wiring rack 650 (the wiring rack 650 is provided with a whole-line structure such as a wire card and a wiring groove). At this time, the first connecting wire 500 includes the connecting wire between the terminal board and the control board 300, but the first connecting wire 500 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, etc.; the above can all achieve the purpose of this application, and its purpose does not deviate from the design idea of ​​the present invention. It will not be repeated here and should all fall within the scope of protection of this application.

[0041] In some embodiments, as Figures 7 to 11 As shown, the wire routing structure includes a wire routing hole 430 and a receiving cavity 440. The first connecting wire 500 includes a wire body 510 and an electrical component 520 disposed within the wire body 510. The wire body 510 is passed through the wire routing hole 430, and the electrical component 520 is placed within the receiving cavity 440. The receiving cavity 440 limits the electrical component 520. This makes the connection between the wire body 510 and the control board 300 less likely to cause a disconnection if the first connecting wire 500 is accidentally pulled. Furthermore, this solution simplifies the positioning of the first connecting wire 500. The portion of the first connecting wire 500 outside the electric control box cover 400 is also neater and less cluttered due to the absence of the electrical component 520. The electrical component 520 comprises a magnetic ring.

[0042] In some embodiments, as Figure 8 and Figure 9 As shown, the wire passing structure further includes a wire channel 450, and the wire body 510 is further arranged in the wire channel 450. Among them, the bend of the wire channel 450 is transitioned through an arc structure (such as chamfer) to eliminate sharp edges and prevent the bend of the wire channel 450 from scratching and abrading the wire body 510.

[0043] In some embodiments, 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 a protruding structure 460 that protrudes away from the middle partition 200. The two protruding structures 460 face each other in the front-to-back direction and together form a wire hole 430, a receiving cavity 440, and a wiring channel 450. The area on the opposite sides of the two protruding structures 460 is larger, making it easier to layout the wire hole 430, the receiving cavity 440, and the wiring channel 450. To prevent electromagnetic interference between different first connecting wires 500, the different first connecting wires 500 are also arranged between the two protruding structures 460 to separate strong and weak currents.

[0044] In some embodiments, as Figures 8 to 11 As shown, the protruding structure 460 of the first cover body 410 is provided with a convex rib 461 protruding forward, and the protruding structure 460 of the first cover body 410 is combined with the protruding structure 460 of the second cover body 420 through the convex rib 461 to form a wire hole 430, a receiving cavity 440 and a wiring channel 450 (as shown in FIG. 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, and a wiring groove is formed between adjacent ribs 461. The wire passing hole 430 includes a wire passing notch, the receiving cavity 440 includes a receiving groove, and the wiring channel 450 includes a wiring groove). This solution has a simple structure and is easy to implement. The wire passing notch and the wiring groove can be provided with undercuts to prevent the wire body 510 from falling out, and the inner side surface of the accommodating groove can be provided with matching ribs, and the matching ribs are interference fit with the electrical component 520 on both sides of the electrical component 520 (so that the electrical component 520 is positioned between the matching ribs on both sides thereof). In this way, after the first connecting wire 500 is installed on the matching part of the first cover body 410, it will not separate from the matching part of the first cover body 410 (that is, the wire body 510 will not fall out of the wire passing notch and the wiring groove, and the electrical component 520 will not fall out of the accommodating groove), which is more conducive to the subsequent installation of the second cover body 420; the interference fit between the electrical component 520 and the matching rib is line contact. Compared with the interference fit in which the electrical component 520 is in surface contact with the inner circumference of the accommodating groove, the electrical component 520 of this scheme is faster to disassemble and assemble in the accommodating groove.

[0045] In some embodiments, as Figures 4 to 7As shown, the first communication 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, the first cover 410 includes a first portion 411 and a second portion 412, the first communication port is opposite to the first portion 411 in the left-right direction, the second portion 412 is located on the rear side of the control board 300, the upper end of the second portion 412 is connected to the rear end of the first portion 411, the second cover 420 is located on the front side of the second portion 412 and below the first portion 411, the upper end of the second cover 420 is matched with the lower end of the first portion 411, and the rear end of the second cover 420 is matched with the front end of the second portion 412 (the opening of the first cover 410 is connected to the second cover 420). The openings of the two cover bodies 420 are connected, the lower part of the first part 411 is provided with a first opening facing downward, the front part of the second part 412 is provided with a second opening facing forward, the opening of the first cover body 410 includes the first opening and the second opening, the upper part of the second cover body 420 is provided with a third opening facing upward, the rear part of the second cover body 420 is provided with a fourth opening facing backward, and the opening of the second cover body 420 includes the third opening and the fourth opening), the two protruding structures 460 are respectively located at the rear end of the second cover body 420 and the front end of the second part 412, the lower end of the second cover body 420 is provided with a third connecting port 421, and the heat dissipation channel 130 is connected to the installation chamber 120 through the third connecting port 421. The control board 300 is completely located in the heat dissipation channel 130, and the third communication port 421 is located below the control board 300. In this way, the air in the installation chamber 120 enters the heat dissipation channel 130 from the third communication port 421. In the process of passing upward through the heat dissipation channel 130, almost all of the air passes through the control board 300, which will better remove the heat on the control board 300, and then enter the heat exchange chamber 110 from the first communication port. This solution has a better heat dissipation effect on the control board 300. Figure 1 and Figure 12 As shown, under the conditions of high ambient temperature, high compressor operating frequency, and high fan speed, compared with the technical solutions of the related art (the two technical solutions have the same operating conditions and operating parameters, and the only structural difference is that the technical solution of the present application has an additional electric control box cover 400), the maximum temperature of the control panel 300 of the technical solution of the present application is at least 20 degrees Celsius lower than the maximum temperature of the control panel of the technical solution of the related art. Moreover, the higher the operating frequency of the compressor and the higher the speed of the fan assembly 610, the greater the temperature difference between the maximum temperature of the control panel 300 of the technical solution of the present application and the maximum temperature of the control panel of the technical solution of the related art. When the control panel of the air conditioner outdoor unit of the related art overheats, it is necessary to reduce the operating frequency of the compressor to protect the control panel from overheating. However, when the air conditioner outdoor unit of the technical solution of the present application is in operation, because the control panel 300 will not overheat, the compressor does not need to reduce the operating frequency.

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

[0047] In some embodiments, as Figures 4 to 7 As shown, the air conditioner outdoor unit also includes: an electric control mounting frame 700 having a second connecting port 710, which is arranged on the middle partition 200 in the mounting chamber 120, and the electric control box cover 400 is installed on the electric control mounting frame 700 on the side of the electric control mounting frame 700 facing away from the middle partition 200, and together with the electric control mounting frame 700, a heat dissipation channel 130 is enclosed, and the first connecting port is connected to the heat dissipation channel 130 through the second connecting port 710.
