[0039] The present invention provides an outdoor unit.

[0040] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the outdoor unit includes a front panel 100, two side panels 210 arranged opposite to each other and a partition 220 located between the two side panels 210, and a compressor cavity 610 and a fan cavity 620 are formed on the opposite sides of the partition 220 respectively. A compressor and an electrical control unit 700 are provided in the compressor cavity 610, and a fan is provided in the fan cavity 620. The fan and the compressor are both electrically connected to the electrical control unit 700; the electrical control unit 700 forms a heat dissipation duct, and the cavity wall of the compressor cavity 610 is provided with an air inlet 211 and a first air outlet 221, and the two ends of the heat dissipation duct are respectively connected to the air inlet 211 and the first air outlet 221.

[0041] In the technical solution of the present invention, the electric control unit 700 is installed in the compressor chamber 610 and communicates with the air inlet 211 and the first air outlet 221 of the compressor chamber 610 via a heat dissipation duct. Air from the outdoor environment can enter the heat dissipation duct through the air inlet 211, and after convective heat exchange with the electric control unit 700, it is discharged to the outdoor environment through the first air outlet 221. It is understood that the temperature of the air in the fan chamber 620 that passes through the heat exchanger will be higher than that of the outdoor air. The present invention directly uses the outdoor air to dissipate heat from the electric control unit 700, and can exchange heat with the electric control unit 700 through the lower temperature air. This improves the heat dissipation effect of the electric control unit 700, can increase the operating temperature threshold of the electric control unit 700, and is conducive to improving the operating performance of the outdoor unit.

[0042] Furthermore, in this embodiment, Figure 2 and Figure 3 As shown, the electrical control unit 700 includes a main control board 710 and a mounting housing 720. The main control board 710 is mounted in the mounting housing 720. One side of the mounting housing 720 is provided with an opening, exposing the side of the main control board 710 where the electrical components are mounted. This increases the area of ​​the electrical control unit 700 exposed within the compressor chamber 610, facilitating heat exchange between the air within the compressor chamber 610 and the electrical control unit 700, thereby further improving the heat dissipation efficiency of the electrical control unit 700. In the event of a malfunction of the main control board 710, the outdoor unit housing can be partially disassembled to conveniently access the main control board 710 for repair. This eliminates the need to remove the main control board 710 from the compressor chamber 610, thereby preserving the wiring between the main control board 710 and the compressor or fan. Furthermore, since the surrounding walls of the compressor chamber 610 are made of sheet metal, safety is ensured even when the main control board 710 is exposed within the compressor chamber 610. Of course, in other embodiments, in order to improve the safety performance of the electronic component 700, a closed shell may also be used to encapsulate the main control board 710.

[0043] Specifically, at least the portion of the front panel 100 corresponding to the press chamber 610 is removable, and the side of the main control board 710 mounting electrical components faces the front panel 100. It will be appreciated that the outdoor unit further includes a chassis 300 and a top cover 400. In this embodiment, at least the aforementioned portion of the front panel 100 is detachably connected to the chassis 300 and the top cover 400. This allows for convenient access to the main control board 710 by removing the portion of the front panel 100 corresponding to the press chamber 610, or by removing the entire front panel 100 to expose the front side of the press chamber 610. Of course, in other embodiments, at least the portion of the top cover 400 corresponding to the press chamber 610 may be removable, with the side of the main control board 710 mounting electrical components facing the top cover 400. This allows for convenient access to the main control board 710 by removing the top cover 400 in the event of a malfunction.

[0044] Furthermore, in this embodiment, a heat sink 711 is mounted on the main control board 710, and the electrical control unit 700 also includes a duct member 730 connected to the mounting housing 720. The heat dissipation duct is formed within the duct member 730, and the heat sink 711 is accommodated within the duct. It will be appreciated that the heat sink 711 has multiple fins, which can significantly increase the heat exchange area of ​​the main control board 710. By accommodating the heat exchanger within the duct, the heat dissipation effect of the main control board 710 can be greatly improved. In addition, the mounting shell 720 and the air duct component 730 can be formed separately and then assembled with the main control board 710, which is conducive to improving the assembly convenience of the electrical control unit 700. The board body of the main control board 710 is snapped into the mounting shell 720, and the air duct component 730 is then installed in the mounting shell 720 and installed corresponding to the heat sink 711, so that the heat sink 711 can be accommodated in the heat dissipation duct. In this way, the main control board 710, the air duct component 730 and the mounting shell 720 are unlikely to interfere with each other. Of course, in other embodiments, the mounting shell 720 can also be formed with a heat dissipation duct, and the side of the mounting shell 720 can be provided with an installation opening corresponding to the structure of the main control board 710, and the main control board 710 is inserted into the mounting shell 720 through the installation opening on the side.

[0045] Furthermore, in this embodiment, the main control board 710 is located outside the air duct component 730. The air duct component 730 is provided with a port corresponding to the radiator 711, which is connected to the heat dissipation duct. The radiator 711 is inserted into the heat dissipation duct through the port. In this way, after the radiator 711 is inserted into the heat dissipation duct, the port can be covered by the plate body of the main control board 710 to reduce the escape of air from the heat dissipation duct into the compressor chamber 610, thereby ensuring that the high-temperature air after heat exchange can be discharged from the compressor chamber 610 through the first air outlet 221, thereby avoiding increasing the temperature within the compressor chamber 610. Of course, in other embodiments, the main control board 710 can also be inserted into the heat dissipation duct together with the radiator 711.

[0046] Furthermore, in this embodiment, Figure 2 and Figure 3 As shown, the heat dissipation duct is formed with a narrow opening 733 at a position relative to the air outlet assembly of the compressor. The heat dissipation duct gradually expands from the narrow opening 733 toward both ends, and the radiator 711 is located on the side of the narrow opening 733 near the first air outlet 221. It can be understood that the gas flowing out of the compressor outlet is high-temperature and high-pressure gas, resulting in a high temperature at the air outlet assembly of the compressor. In this embodiment, the heat dissipation duct is an overall gradually converging and expanding structure. The heat dissipation duct can form an airflow acceleration zone at the narrow opening 733, allowing the airflow to pass through the narrow opening as quickly as possible, which is conducive to reducing the temperature rise of the airflow before it flows through the radiator 711, so that the temperature of the airflow that exchanges heat with the radiator 711 is lower, which can better remove the heat from the radiator 711 and improve the heat exchange efficiency.

[0047] Furthermore, in this embodiment, Figure 2 As shown, one side of the air duct member 730 is disposed opposite and close to the front panel 100 and parallel to the front panel 100, while the other side is recessed toward the front panel 100 to form the narrow opening 733. In this way, while utilizing the recessed structure of the air duct member 730 to form the narrow opening 733, an escape space can also be formed on the recessed side of the air duct member 730 to effectively avoid the corresponding air outlet assembly, thereby fully utilizing the space within the press chamber 610 and maximizing the space utilization of the heat dissipation air duct, which is beneficial for ensuring the heat dissipation effect of the electronic control unit 700.

[0048] Furthermore, in this embodiment, Figure 4As shown, the duct member 730 includes a first duct member 731 and a second duct member 732. The heat dissipation duct is formed by the first duct member 731 and the second duct member 732. The first duct member 731 and the mounting shell 720 are integrally formed, while the second duct member 732 is independently formed. In this way, a port can be designed only in the second duct member 732, and the area of ​​the port can be designed to be large to facilitate the insertion of the heat sink 711. Except for the position relative to the heat sink 711, the rest of the port can be covered by the first duct member 711, thereby forming a heat dissipation duct. Furthermore, since the first duct member 731 is integrally formed with the mounting shell 720, the connection stability between the duct member 730 and the mounting shell 720 can be guaranteed after the second duct member 732 is assembled. Of course, in other embodiments, the duct member 730 can also be integrally formed as a whole and then assembled with other parts of the electrical control 700.

[0049] Furthermore, in this embodiment, please refer to Figure 3 and Figure 4 , the first air duct component 731 is in the shape of a plate and is formed on one side edge of the mounting shell 720. The second air duct component 732 has a portion covering the mounting shell 720, and the end of the second air duct component 732 away from the first air duct component 731 is in the shape of a hollow cylinder. In this way, the port at one end of the heat dissipation duct will be constructed by the hollow cylindrical structure at the end of the second air duct component 732, and the port at the other end will be formed by the first air duct component 731 and the second air duct component 732. This allows both ends of the heat dissipation duct to form a circumferentially closed structure, which can have a good gathering effect on the airflow and is conducive to promoting the airflow into or out of the heat dissipation duct. Specifically, the first air duct component 731 is a curved plate-like structure to form a depression here, thereby forming the aforementioned avoidance space. The position where the second air duct component 732 and the first air duct component 731 are combined is set in accordance with the shape to better avoid other components.

[0050] Furthermore, in this embodiment, the radiator 711 is mounted on the side of the main control board 710 where the electrical components are mounted, and the main control board 710 is sandwiched between the mounting shell 720 and the air duct member 730. In this way, the main control board 710 can be limited by the air duct member 730. One side of the mounting shell 720 can be designed as an open side, and the main control board 710 is installed into the mounting shell 720 from the open side. The electrical components thereon are also exposed through the open side. The mounting shell 720 does not need to be provided with a separate limiting structure on this side. After the air duct member 730 is connected to the mounting shell 720, the main control board 710 can be restricted from being removed from the mounting shell 720 by the air duct member 730. Of course, in other embodiments, the electrical components and the radiator 711 can also be mounted on opposite sides of the main control board 710, and the air duct member 730 is connected to the mounting shell 720 on the side where the radiator 711 is located.

[0051] Furthermore, in this embodiment, Figure 1 and Figure 2 As shown, the first air outlet 221 is provided on the partition 220, the air inlet 211 is provided on the side panel 210 corresponding to the compressor chamber 610, the opposite ends of the air duct component 730 are respectively connected to the partition 220 and the side panel 210, and the two ends of the heat dissipation duct are respectively connected to the air inlet 211 and the first air outlet 221. In this way, the outlet of the heat dissipation duct can be connected to the fan chamber 620 through the first air outlet 221. The operation of the fan in the fan chamber 620 can form a negative pressure at the first air outlet 221, prompting air from the outdoor environment to enter the heat dissipation duct from the air inlet 211, and then enter the fan chamber 620 through the first air outlet 221. Then, driven by the fan, the air is discharged to the outdoor environment through the outlet of the fan chamber 620. Under the turbulent action of the fan, the air velocity in the heat dissipation duct is relatively high, which is conducive to improving the convective heat exchange effect between the air and the radiator 711, thereby further improving the heat dissipation effect of the electronic control unit 700. Of course, in other embodiments, the air inlet 211 and the first air outlet 221 can be set on other walls of the compressor chamber 610, and a fan can be installed in the heat dissipation duct to improve the convective heat exchange effect.

[0052] Furthermore, in this embodiment, the air duct member 730 is connected to the partition 220 or the side panel 210 by means of a snap or screw fastener. It is understood that the side panel 210 to which the air duct member 730 is connected should be the side panel 210 on the side of the press chamber 610. In this embodiment, the air duct member 730 can achieve a stable connection with the partition 220 and the side panel 210. After the front panel 100 is removed, the air duct member 730 can also be stably installed in the press chamber 610, facilitating maintenance of the main control panel 710. Furthermore, the electrical control unit 700 can be easily removed from the press chamber 610 for replacement. Of course, in other embodiments, the air duct member 730 can also be connected to the top cover 400 and fixedly installed in the press chamber 610.

[0053] Furthermore, in this embodiment, Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the front panel 100 is provided with a second air outlet 110 corresponding to the fan cavity 620. The second air outlet 110 is provided with a motor frame 120. The fan includes a drive motor 510 and an axial flow impeller 520. The drive motor 510 is mounted on the motor frame 120 and is driven by the axial flow impeller 520. This eliminates the need for a separate bracket within the fan cavity 620 for fan installation, reducing space occupied within the fan cavity 620. By utilizing the space on the front panel 100 at the second air outlet 110 to provide the motor frame 120, the present invention facilitates a compact design of the outdoor unit. It will be appreciated that the motor frame 120 is preferably provided so as not to interfere with the air flow from the fan cavity 620 at the second air outlet 110. Furthermore, the second air outlet 110 is provided with an air outlet mesh cover. Of course, in other embodiments, a separate bracket may be provided within the fan cavity 620 for fan installation.

[0054] Furthermore, in this embodiment, Figure 5 and Figure 6As shown, the motor frame 120 includes a fixing base 121 and a plurality of adapter legs 122. The plurality of adapter legs 122 are spaced apart along the circumference of the fixing base 121. One end of the adapter leg 122 is connected to the fixing base 121, and the other end is connected to the edge of the second air outlet 110. In this way, the fixing base 121 is stably connected to the second air outlet 110 through the support of the adapter legs 122, thereby ensuring the stable installation of the drive motor 510. Specifically, the fixing base 121 is provided with a through hole for the drive motor 510 to be inserted and installed. The outer periphery of the drive motor 510 is provided with a plurality of mounting legs 511. The mounting legs 511 and the fixing base 121 are provided with corresponding connection holes for fasteners to penetrate and lock, so as to achieve the installation of the drive motor 510 on the motor frame 120. Of course, in other embodiments, the motor frame 120 may be connected only to the lower side of the second air outlet 110 at its lower portion to support the drive motor 510 below the drive motor 510 .

[0055] Furthermore, in this embodiment, Figure 6 As shown, a first reinforcement groove 123 is provided on the front side of the motor frame 120. The first reinforcement groove 123 is formed in at least one of the fixing base 121 and the adapter leg 122 to enhance the structural strength of the motor frame 120, thereby ensuring that the motor frame 120 reliably supports the drive motor 510 and the axial flow impeller 520. At the same time, the weight of the motor frame 120 is reduced, achieving a lightweight design. The first reinforcement groove 123 is recessed toward the axial flow impeller 520.

[0056] Specifically, in order to ensure the structural strength of the fixing seat 122 and the adapter leg 122, in one embodiment, the above-mentioned first reinforcement groove 123 is provided on the fixing seat 122 and the adapter leg 122. At this time, the first reinforcement groove 123 provided on the fixing seat 122 is configured as an annular groove, and the driving motor 510 is inserted into the inner ring side of the annular groove and connected to the bottom wall of the annular groove; the first reinforcement groove 123 provided on the adapter leg 122 is configured as a strip groove. As can be understood, the annular groove and the inner annular wall of the annular groove constitute a through-hole for inserting and installing the drive motor 510, which can increase the effective contact area between the drive motor 510 and the fixing base 122 and improve the stability of the connection between the drive motor 510 and the fixing base 122. A plurality of mounting feet 511 are protruding from the outer periphery of the drive motor 510. When the drive motor 510 is partially inserted into the inner annular side, the mounting feet are placed on the surface of the bottom wall of the inner annular groove facing away from the air outlet grille 20. The drive motor 510 can be installed on the fixing base 122 by means of screw locking, snap connection, etc. The strip groove extends along the extension direction of the adapter leg 122 and can partially extend to the connection between the adapter leg 122 and the front panel 100, and to the connection between the adapter leg 122 and the fixing base 122, further improving the structural strength of the motor frame 120 and improving the connection strength between the motor frame 120 and the front panel 100.

[0057] Furthermore, in this embodiment, the motor frame 120 is integrally formed with at least the portion of the front panel 100 corresponding to the fan chamber 620. In this way, the production efficiency of the outdoor unit can be improved by integrally processing the motor frame 120 and the front panel 100. Specifically, the two are integrally formed by stamping, so that the waste generated by stamping the second air outlet 110 of the front panel 100 during the production process can be reasonably utilized, saving costs. Of course, in other embodiments, the motor frame 120 can also be independently formed and then connected to the second air outlet 110 of the front panel 100 by welding, snapping, etc.

[0058] It can be understood that the front panel 100 includes two parts, the first part is used to enclose the press cavity 610, and the second part is used to enclose the fan cavity 620, wherein the motor frame 120 and the second part can be integrally processed and formed, and the first part is independently formed and detachably arranged in the press cavity 610. When the electrical control unit 700 needs to be inspected, only the first part needs to be removed; or, the aforementioned first part and second part can be integrally processed and formed, that is, the entire front panel 100 is integrally formed. In this way, the production efficiency and assembly efficiency of the front panel 100 can be further improved.

[0059] The present invention also proposes an air conditioner, which includes an outdoor unit. The specific structure of the outdoor unit refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0060] The above descriptions are merely optional embodiments of the present invention and do not limit the scope of protection of the present invention. All equivalent structural transformations made using the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields within the scope of the present invention are included in the scope of protection of the present invention.
