[0057] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0058] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0059] First, see Figures 1 to 6 An embodiment of the present application provides an air-conditioning outdoor unit 1 , which includes an electric control box 10 and an outdoor unit body 20 .

[0060] See also Figures 2 to 4 The electric control box 10 includes a first housing 11, a driving board 12 and a first radiator 13. The first housing 11 is formed with an inner cavity 111 and a first opening 112 communicating with the inner cavity 111. The driving board 12 is disposed in the inner cavity 111. The first radiator 13 is disposed corresponding to the first opening 112 and one end of the first radiator 13 is located in the inner cavity 111 of the first housing 11, and the other end is located outside the first housing 11. The first radiator 13 is used to transfer the heat in the first housing 11 to the outside of the first housing 11, which is beneficial to the heat dissipation in the first housing 11.

[0061] See also Figure 1 The outer machine body 20 is formed with a heat dissipation duct 211 and a second opening 212 connected to the heat dissipation duct 211. The electric control box 10 is arranged corresponding to the second opening 212 and one end of the first radiator 13 located outside the first shell 11 extends into the heat dissipation duct 211. The end of the electric control box 10 away from the first opening 112 is located outside the outer machine body 20.

[0062] In the embodiment of the present application, the first radiator 13 penetrates the first housing 11, and one end of the first radiator 13 located outside the first housing 11 extends into the heat dissipation duct 211, so that the first radiator 13 can transfer the heat in the first housing 11 to the heat dissipation duct 211, so as to dissipate heat with the help of the external machine body 20, thereby improving the heat dissipation effect of the electric control box 10; and the first radiator 13 can also bring the cold air in the external machine body 20 into the electric control box 10, thereby accelerating the cooling speed in the electric control box 10. The side of the electric control box 10 away from the first opening 112 is located outside the external machine body 20. Compared with the related art in which the entire electric control box is placed inside the external machine body, the electric control box 10 and the external machine body 20 can be assembled directly outside the external machine body 20, thereby reducing obstacles in the assembly process of the two and accelerating the assembly efficiency. Moreover, part of the electric control box 10 is located outside the external machine body 20, which is also conducive to the operator to directly perform maintenance operations on the electric control box 10 outside the external machine body 20, which will be described in more detail below.

[0063] Combination Figure 4 One end of the first radiator 13 extending into the heat dissipation duct 211 may include a plurality of first heat dissipation fins 131 arranged at intervals to increase the heat dissipation area of ​​the first radiator 13 in the heat dissipation duct 211 and improve the heat dissipation speed of the electric control box 10. At the same time, the cold amount in the external machine body 20 absorbed by the first radiator 13 may be increased, thereby accelerating the cooling speed of the electric control box 10.

[0064] It is understandable that one end of the first radiator 13 located in the inner cavity 111 can directly contact the driving board 12, so that the heat generated by the driving board 12 can be directly transferred to the first radiator 13, so that the first radiator 13 is further transmitted to the heat dissipation duct 211 in the outer body 20. Of course, the first radiator 13 may not directly contact the driving board 12, but the airflow in the inner cavity 111 may be passed to the first radiator 13, and then the heat is transmitted from the first radiator 13 to the heat dissipation duct 211 in the outer body 20, and the embodiment of the present application is not limited to this.

[0065] In the present application, see Figure 2 and Figure 3 The electric control box 10 further includes a second radiator 14, which is located in the inner cavity 111 and in contact with the driving board 12. The second radiator 14 is spaced apart from the first radiator 13, so that the heat generated by the driving board 12 can be directly transferred to the second radiator 14, and when the airflow in the inner cavity 111 flows, the heat of the second radiator 14 can be further transferred to the first radiator 13, and then transmitted from the first radiator 13 to the heat dissipation duct 211 in the outer machine body 20. Of course, when the second radiator 14 is provided in the electric control box 10, the first radiator 13 can also be in contact with the driving board 12, which is not limited thereto.

[0066] The first heat sink 13 may include a plurality of second heat sink fins 132 disposed at intervals at one end of the inner cavity 111, and the second heat sink 14 may include a plurality of third heat sink fins 141 disposed at intervals. The third heat sink fins 141 may be parallel to or intersect with the second heat sink fins 132. In the embodiment of the present application, the third heat sink fins 141 are substantially parallel to the second heat sink fins 132, so as to facilitate better transmission of heat therebetween under the flow of airflow.

[0067] Combination Figure 3 and Figure 4 The first heat sink 13 may further include a first mounting plate 133, and the first heat dissipating fins 131 and the second heat dissipating fins 132 may be mounted on opposite sides of the first mounting plate 133. The first mounting plate 133 is used to provide a mounting carrier for the first heat dissipating fins 131 and the second heat dissipating fins 132, and the first heat sink 13 may be mounted in the first housing 11 through the first mounting plate 133.

[0068] The plurality of third heat dissipating fins 141 of the second heat sink 14 can be directly mounted on the driving board 12, and the second heat sink 14 can also include a second mounting plate (not shown in the figure) for mounting the third heat dissipating fins 141, and the second heat sink 14 can be mounted on the driving board 12 through the second mounting plate. Of course, the second heat sink 14 can also be mounted on the first housing 11 or other devices in the first housing 11 instead of on the driving board 12, so that the second heat sink 14 can contact with the driving board 12 to achieve heat transfer.

[0069] In order to speed up the airflow speed in the inner cavity 111, so that the first radiator 13 can collect more heat in the inner cavity 111, and the cold in the external machine body 20 absorbed by the first radiator 13 can be diffused in the inner cavity 111, the first shell 11 is also formed with a first air inlet (not shown in the figure) and a first air outlet (not shown in the figure) connected to the inner cavity 111, so that the airflow can enter the inner cavity 111 through the first air inlet to drive the heat in the inner cavity 111 to flow so as to be transferred to the first radiator 13, and then the airflow flows out of the inner cavity 111 through the first air outlet. It can be understood that in the process of the airflow flowing from the first air inlet to the first air outlet, at least part of the heat in the inner cavity 111 can also be taken away, achieving a certain heat dissipation effect.

[0070] In an exemplary solution, the first air inlet and the first air outlet can be arranged at a portion of the first housing 11 located outside the external machine body 20, so that the airflow outside the external machine body 20 can enter the first housing 11 and drive the heat flow in the first housing 11. The airflow outside the external machine body 20 can enter the first housing 11 directly with the help of natural wind, etc., and the airflow outside the external machine body 20 can also enter the first housing 11 with the help of the cooling fan 15 arranged in the electric control box 10, which can be seen in Figure 2 and Figure 3 When the cooling fan 15 is started, it can drive the airflow outside the external machine body 20 to enter the inner cavity 111 through the first air inlet and flow out of the inner cavity 111 through the first air outlet. The wind force and opening and closing control of the cooling fan 15 are more flexible than the natural wind force.

[0071] Furthermore, along the air outlet path of the cooling fan 15, the first radiator 13 is located upstream of the second radiator 14. In this way, after the first radiator 13 brings the cold air in the external machine body 20 into the inner cavity 111, the cooling fan 15 can blow the cold air on the first radiator 13 to the second radiator 14 and the driving plate 12, thereby accelerating the heat dissipation and cooling speed of the second radiator 14 and the driving plate 12. The airflow path driven by the cooling fan 15 in the inner cavity 111 can be as follows: Figure 3 The path indicated by the arrow in the middle may also be other flow paths, which is not limited to this.

[0072] In another exemplary solution, the first air inlet and the first air outlet may both be located in the heat dissipation duct 211. In this case, the airflow in the electric control box 10 may be directly driven by the airflow in the external machine body 20, so that there is no need to set up a heat dissipation fan 15 in the electric control box 10, which can reduce the volume and manufacturing cost of the electric control box 10.

[0073] It should be noted that if the first air inlet and the first air outlet are located in the heat dissipation duct 211, the first air inlet, the first air outlet and the first opening 112 can be located on the same plate of the first shell 11, or the first air inlet, the first air outlet and the first opening 112 can be located on different plates of the first shell 11. Figure 1 The first housing 11 includes a first plate 1181 and a first peripheral side plate 1182 disposed around the first plate 1181, the first peripheral side plate 1182 is connected to the first plate 1181, the first opening 112 can be disposed on the first plate 1181, and the first air inlet and the first air outlet can be provided with the first peripheral side plate 1182. Furthermore, the first air inlet and the first air outlet can be disposed on opposite sides of the first peripheral side plate 1182, so that the airflow flows more smoothly, which is not limited thereto.

[0074] The first air inlet may be located at the bottom of the first housing 11, and the first air outlet may be located at the top of the first housing 11, without limitation. A dustproof net may be provided at the first air inlet and the first air outlet to prevent dust and impurities from entering the electric control box 10.

[0075] In the embodiment of the present application, only part of the first radiator 13 may be disposed in the heat dissipation duct 211 of the external machine body 20, or part of the first radiator 13 and part of the first shell 11 may be disposed in the heat dissipation duct 211 of the external machine body 20. When part of the first shell 11 is disposed in the external machine body 20, the part of the first shell 11 disposed in the external machine body 20 may be directly cooled by the cold air in the external machine body 20, which can accelerate the cooling speed of the first shell 11 compared to the case where the entire first shell 11 is disposed outside the external machine body 20 and is cooled only by the cold air transferred by the first radiator 13.

[0076] See also Figure 1 The electric control box 10 may further include a fixing member 117, which may be disposed outside the first housing 11 and connect the first housing 11 and the external machine body 20. Further, the fixing member 117 may be connected to the first peripheral side plate 1182 of the first housing 11, and the position of the fixing member 117 in the thickness direction of the first housing 11 is adjustable. For example, the fixing member 117 may be disposed on a side of the first peripheral side plate 1182 close to the first plate 1181, or disposed in the middle of the first peripheral side plate 1182 in the thickness direction of the first housing 11, or disposed on a side of the first peripheral side plate 1182 away from the first plate 1181. The position of the fixing member 117 on the first peripheral side plate 1182 may be flexibly designed in combination with actual needs.

[0077] The fixing member 117 may include a first fixing plate 1171 and a second fixing plate 1172 arranged at an angle, the first fixing plate 1171 may be connected to the first housing 11 (such as the first peripheral side plate 1182), and the second fixing plate 1172 may be connected to the external machine body 20. The angle between the first fixing plate 1171 and the second fixing plate 1172 may be 90°, and the first fixing plate 1171 and the second fixing plate 1172 may be an integrally formed structure.

[0078] The first fixing plate 1171 and the first shell 11 , and the second fixing plate 1172 and the external machine body 20 may be connected by means of screws or the like, which is not limited thereto.

[0079] The electric control box 10 may be provided with one fixing member 117 or multiple fixing members 117. For example, the electric control box 10 may be provided with two fixing members 117, and the two fixing members 117 are respectively located on opposite sides of the first shell 11 to improve the assembly stability between the electric control box 10 and the external machine body 20.

[0080] See also Figure 3 The electric control box 10 may further include a heater 16, which is disposed in the inner cavity 111. The heater 16 may be used to generate heat, so that when the temperature in the inner cavity 111 is lower than the operating temperature of each device in the inner cavity 111, the heater 16 may be controlled to generate heat to increase the temperature in the inner cavity 111 so that each device can work normally.

[0081] See also Figure 3 The electric control box 10 may further include a mounting bracket 17, which is located in the inner cavity 111 and connected to the shell 11. At least one of the drive board 12, the first radiator 13, the second radiator 14, the cooling fan 15, and the heater 16 may be mounted on the mounting bracket 17, so that at least one of the drive board 12, the first radiator 13, the second radiator 14, the cooling fan 15, and the heater 16 may be first assembled with the mounting bracket 17, and then assembled together in the first shell 11, which is more convenient to assemble.

[0082] The mounting bracket 17 may include a second plate 171 and a second peripheral side plate 172 disposed around the periphery of the second plate 171, the second peripheral side plate 172 is connected to the second plate 171, and at least one of the driving plate 12, the first radiator 13, the second radiator 14, the cooling fan 15, and the heater 16 may be mounted on the second plate 171 and / or the second peripheral side plate 172. The second plate 171 and / or the second peripheral side plate 172 may be connected to the first housing 11, for example, the second plate 171 may be connected to the first plate 1181 and / or the second peripheral side plate 172 may be connected to the first peripheral side plate 1182, which is not limited thereto.

[0083] See also Figure 1 and Figure 2 The first housing 11 includes a box body 113 and a cover body 114. The box body 113 is formed with a first opening 112 and a third opening 115 opposite to the first opening 112. The cover body 114 is arranged corresponding to the third opening 115 and connected to the box body 113. The cover body 114 and the box body 113 enclose an inner cavity 111, and the cover body 114 is located outside the external machine body 20. The cover body 114 is located outside the external machine body 20. In this way, when the electric control box 10 needs to be repaired, the electric control box 10 can be repaired directly outside the external machine body 20. Compared with the related art in which the electric control box is placed in the external machine body and needs to be taken out of the external machine body during maintenance, the maintenance operation is more convenient.

[0084] The box body 113 and the cover body 114 may be detachably connected, rotatably connected, etc., without limitation. If the box body 113 and the cover body 114 are detachably connected, the cover body 114 may be removed from the box body 113 when the electric control box 10 is inspected, and the cover body 114 and the box body 113 may be assembled after the inspection is completed. If the box body 113 and the cover body 114 are rotatably connected, the cover body 114 may be rotated relative to the box body 113 at a certain angle when the electric control box 10 is inspected, so that the components in the inner cavity 111 can be exposed without removing the cover body 114 for inspection and maintenance operations. The box body 113 and the cover body 114 may be rotatably connected through a rotating member 119, and the rotating member 119 may be a hinge, etc., without limitation.

[0085] The inner cavity 111 may be formed in the box body 113, and the inner cavity 111 may also include a first chamber 1111 and a second chamber 1112. The first chamber 1111 is formed in the box body 113, and the second chamber 1112 is formed in the cover body 114. Functional devices may be disposed in the first chamber 1111 and the second chamber 1112, that is, functional devices are disposed in both the box body 113 and the cover body 114. Compared with the case where the inner cavity 111 is only formed in the box body 113 and all the functional devices are disposed in the box body 113, the laying area of ​​the functional devices can be increased, so that when the cover body 114 is opened relative to the box body 113, the functional devices can be better spread out, which is convenient for maintenance.

[0086] The driving plate 12 , the first radiator 13 , the second radiator 14 , the cooling fan 15 , the heater 16 and the mounting bracket 17 may all be disposed in the first chamber 1111 , and this is not limited.

[0087] The device disposed in the first chamber 1111 can be defined as a first functional device. For example, the first functional device is disposed on the driving board 12, and the device disposed in the second chamber 1112 can be defined as a second functional device. The output power of the first functional device can be higher than the output power of the second functional device. In this way, when the electric control box 10 is working, the heat in the first chamber 1111 will be higher than the heat in the second chamber 1112. Compared with the second chamber 1112, the first chamber 1111 is closer to the external machine body 20. Therefore, the heat in the first chamber 1111 is easier to dissipate and cool down than the heat in the second chamber 1112.

[0088] It should be noted that if the box body 113 and the cover body 114 are rotatably connected, please refer to Figure 2 and Figure 4When the cover 114 is rotated and opened relative to the box body 113, the maximum opening angle between the cover 114 and the box body 113 can be approximately 180°, so that after the cover 114 and the box body 113 are opened, it is convenient for the user to inspect the box body 113 and the functional components in the cover 114. Of course, the maximum opening angle between the box body 113 and the cover 114 can also be greater than or equal to 90° and less than 180°, etc., which can achieve the effect of facilitating maintenance for operators. In the embodiment of the present application, the maximum opening angle between the box body 113 and the cover 114 is not specifically limited.

[0089] Since the box body 113 and the cover body 114 are both provided with functional devices, when wiring, part of the line will cross the box body 113 and the cover body 114. In order to avoid the problem of line extrusion when the box body 113 and the cover body 114 are relatively opened and closed, refer to Figure 2 , a wire tying bridge 110 may be provided in the box body 113 and the cover body 114. In this way, if the line spans the box body 113 and the cover body 114, the line can be fixed to the wire tying bridge 110 in the box body 113 and the cover body 114, and some bending margins are reserved. Compared with the line not fixed by the wire tying bridge, the floating part of the line is relatively small during the relative opening and closing of the box body 113 and the cover body 114, and the problem of the line being squeezed by the box body 113 and the cover body 114 is not likely to occur. In addition, the provision of the wire tying bridge 110 is conducive to the planning and arrangement of the wiring in the electric control box 10, which is conducive to maintenance.

[0090] It should be noted that, in addition to designing a rotatable connection between the box body 113 and the cover body 114, the box body 113 can also be designed to be rotatably connected to a rotating plate (not shown in the figure) in the inner cavity 111, and the rotating plate is provided with functional devices, so that when the rotating plate rotates relative to the box body 113, the functional devices on the rotating plate can also be spread out, which is convenient for operators to inspect. Among them, if a rotating plate is provided in the inner cavity 111, the functional devices on the rotating plate can be provided on the side of the rotating plate away from the cover body 114 and / or the side of the rotating plate close to the cover body 114, and the functional devices in the box body 113 can be provided on the side of the rotating plate away from the cover body 114.

[0091] Among them, the functional device on the rotating plate can be defined as a third functional device, and the output power of the third functional device can be lower than the output power of the first functional device set on the box body 113, so that the high heat generated by the first functional device when working can be dissipated by the first radiator 13 in a timely and efficient manner and the cooling speed is faster.

[0092] See also Figure 2The first housing 11 further includes an annular protrusion 116, which is arranged corresponding to the third opening 115 of the box body 113. The annular protrusion 116 is installed in one of the box body 113 and the cover body 114 and protrudes relative to one of the box body 113 and the cover body 114. The annular protrusion 116 is also sealed and connected to the inner wall of the other of the box body 113 and the cover body 114. When the box body 113 and the cover body 114 are relatively closed, the box body 113 and the cover body 114 are tightly sealed, which can achieve the effect of dustproof and water-repellent.

[0093] The annular protrusion 116 is also sealed and connected to the inner wall of the other one of the box body 113 and the cover body 114, which can be: the annular protrusion 116 is also sealed and connected to the inner wall of the other one of the box body 113 and the cover body 114 through a sealing ring 1161. The sealing ring 1161 can be installed on the annular protrusion 116 by bonding or the like and protrudes relative to the annular protrusion 116, so that when the box body 113 and the cover body 114 are closed, the sealing ring 1161 will be squeezed and deformed to achieve a better sealing effect.

[0094] The annular protrusion 116 may be disposed on the cover 114, for example, the annular protrusion 116 and the cover 114 may be an integral structure, etc., and a sealing ring 1161 may be disposed on the side of the annular protrusion 116 away from the cover 114. The annular protrusion 116 may also be disposed on the box body 113, for example, the annular protrusion 116 and the box body 113 may be an integral structure, etc., and a sealing ring 1161 may be disposed on the side of the annular protrusion 116 away from the box body 113.

[0095] In the embodiment of the present application, the annular protrusion 116 is arranged on the box body 113 and protrudes relative to the box body 113. When the box body 113 and the cover body 114 are closed, the sealing ring 1161 on the side of the annular protrusion 116 facing away from the box body 113 can abut against the inner wall of the cover body 114 and be squeezed and deformed by the inner wall of the cover body 114, thereby achieving sealing when the box body 113 and the cover body 114 are closed.

[0096] Specifically, if the second chamber 1112 is formed in the cover 114, the depth of the second chamber 1112 in the thickness direction of the electric control box 10 may be less than or equal to the sum of the thickness of the annular protrusion 116 and the thickness of the sealing ring 1161. Since the second chamber 1112 formed in the cover 114 is shallower than the first chamber 1111 formed in the box body 113, the annular protrusion 116 is formed on the box body 113, so that when the box body 113 and the cover 114 are closed, the sealing ring 1161 on the annular protrusion 116 extends into the second chamber 1112 and abuts against the inner wall of the second chamber 1112, and the annular protrusion 116 with a smaller thickness is less likely to affect the opening and closing of the box body 113 and the cover 114.

[0097] The sealing ring 1161 can be any sealing member such as a rubber sealing ring, and is not limited thereto. The setting of the sealing ring 1161 can prevent rainwater from entering the inner cavity 111 through the gap between the box body 113 and the cover body 114, thereby achieving a good sealing effect.

[0098] After the box body 113 and the cover body 114 are closed, they can be fixed by means of bolts or the like, which is not limited thereto.

[0099] See also Figure 5 A self-locking sheath 18 is also provided at the bottom of the electric control box 10, so that the electric control box 10 can meet the requirements of indoor and outdoor wiring while also meeting the IP54 waterproofing, and preventing the bottom water from splashing into the inside of the electric control box 10. It is understandable that the self-locking sheath 18 can be provided at the part of the electric control box 10 located outside the external machine body 20, so as to facilitate the wiring work. Among them, the self-locking sheath 18 can include a thin-wire self-locking sheath and a thick-wire self-locking sheath, etc., and can be flexibly designed in combination with the use requirements, and there is no limitation on this.

[0100] See also Figure 1 The external unit body 20 includes a second housing 21, a fan 22 and a refrigerant assembly 23. The second housing 21 is formed with a heat dissipation duct 211, a second air inlet (not shown in the figure) and a second air outlet 213 connected to the heat dissipation duct 211. The fan 22 is located in the heat dissipation duct 211. The refrigerant assembly 23 includes a refrigerant pump. The fan 22 can be used to drive the air flow in the heat dissipation duct 211. The refrigerant pump can be used to cool the heat dissipation duct 211. The refrigerant pump can be a fluorine pump, etc., which is not limited to this.

[0101] The second air inlet 213 may be located at the bottom of the second housing 21, and the second air outlet 213 may be located at the top of the second housing 21. A dust screen 24 may be provided at the second air inlet and the second air outlet 213 to prevent dust and impurities from entering the heat dissipation air duct 211.

[0102] The drive board 12 in the electric control box 10 can be electrically connected to the refrigerant pump and / or the fan 22. If the drive board 12 is electrically connected to the refrigerant pump, the drive board 12 can be regarded as a refrigerant pump control board, if the drive board 12 is electrically connected to the fan 22, the drive board 12 can be regarded as a fan control board, and if the drive board 12 is electrically connected to both the refrigerant pump and the fan 22, the drive board 12 can be regarded as a two-in-one control board of the refrigerant pump and the fan.

[0103] It should be noted that if the drive board 12 is only electrically connected to one of the refrigerant pump and the fan 22, the electric control box 10 also includes a control board electrically connected to the other of the refrigerant pump and the fan 22, and a third radiator (not shown in the figure) can be provided on the control board so that the heat on the control board can be dissipated through the third radiator. Among them, along the air outlet path of the cooling fan 15, the third radiator can be arranged downstream of the first radiator 13, so that after the first radiator 13 brings the cold air in the external machine body 20 into the inner cavity 111, the cooling fan 15 can blow the cold air on the first radiator 13 to the third radiator and the control board, thereby accelerating the heat dissipation and cooling speed of the third radiator and the control board. The structure of the third radiator and the second radiator 14 and their arrangement in the electric control box 10 can be roughly similar, and no further description is given.

[0104] It is worth mentioning that see Figure 1 The refrigerant assembly 23 may be disposed in the heat dissipation duct 211, see Figure 7 The refrigerant assembly 23 may also be disposed outside the second shell 21 and communicated with the heat dissipation duct 211 through a pipeline or the like, which is not limited in the embodiment of the present application.
