Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

Referring to fig. 1 to 6, an embodiment of the present application provides an air conditioner outdoor unit 1, wherein the air conditioner outdoor unit 1 includes an electric control box 10 and an outdoor unit main body 20.

Referring to fig. 2 to 4, the electronic control box 10 includes a first housing 11, a driving plate 12 and a first heat sink 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 plate 12 is disposed in the inner cavity 111, the first heat sink 13 is disposed corresponding to the first opening 112, one end of the first heat sink is located in the inner cavity 111 of the first housing 11, and the other end of the first heat sink is located outside the first housing 11. The first radiator 13 is used for transferring heat in the first housing 11 to the outside of the first housing 11, so as to facilitate the dissipation of heat in the first housing 11.

Referring to fig. 1, the outer machine body 20 is formed with a heat dissipation air channel 211 and a second opening 212 communicated with the heat dissipation air channel 211, the electric control box 10 is arranged corresponding to the second opening 212, one end of the first radiator 13 located outside the first shell 11 stretches into the heat dissipation air channel 211, and one end of the electric control box 10 away from the first opening 112 is located outside the outer machine body 20.

In this embodiment, the first radiator 13 penetrates through the first housing 11, and one end of the first radiator 13 located outside the first housing 11 extends into the heat dissipation air channel 211, so that the first radiator 13 can transfer the heat in the first housing 11 into the heat dissipation air channel 211 to dissipate the heat by means of the external machine main body 20, thereby improving the heat dissipation effect of the electronic control box 10; and the first radiator 13 can also bring the cool air in the outer machine main body 20 into the electric control box 10, so as to accelerate the cooling speed in the electric control box 10. Compared with the prior art in which the whole electronic control box is arranged inside the outer machine body, the electronic control box 10 can be directly assembled with the outer machine body 20 outside the outer machine body 20, so that the obstruction in the assembly process of the electronic control box 10 and the outer machine body 20 is reduced, and the assembly efficiency is accelerated. And the electric control box 10 is partially located outside the outer machine main body 20, which is also beneficial for an operator to directly overhaul the electric control box 10 outside the outer machine main body 20, and the like, which will be described in more detail below.

Referring to fig. 4, an end of the first radiator 13 extending into the heat dissipation air duct 211 may include a plurality of first heat dissipation fins 131 disposed at intervals, so as to increase a heat dissipation area of the first radiator 13 in the heat dissipation air duct 211, improve a heat dissipation speed of the electronic control box 10, and meanwhile, improve a cooling capacity of the external machine main body 20 absorbed by the first radiator 13, and accelerate a cooling speed of the electronic control box 10.

It will be appreciated that the end of the first heat sink 13 located in the inner cavity 111 may be in direct contact with the driving board 12, such that heat generated by the driving board 12 may be directly transferred to the first heat sink 13, so that the first heat sink 13 is further transferred into the heat dissipation air channel 211 in the outer machine body 20. Of course, the first radiator 13 may not be directly contacted with the driving board 12, but the heat in the inner cavity 111 may be transferred to the first radiator 13 by the airflow in the inner cavity 111, and then be transferred from the first radiator 13 to the heat dissipation air duct 211 in the outer machine body 20, which is not limited in this embodiment of the present application.

In this embodiment, referring to fig. 2 and 3, the electronic control box 10 further includes a second radiator 14, where the second radiator 14 is located in the inner cavity 111 and is in contact with the driving board 12, and the second radiator 14 is spaced from the first radiator 13, so that heat generated by the driving board 12 can be directly transferred to the second radiator 14, and when airflow in the inner cavity 111 flows, heat of the second radiator 14 can be further transferred to the first radiator 13, and then is transferred to the heat dissipation air duct 211 in the outer machine main body 20 by the first radiator 13. Of course, when the second radiator 14 is provided in the electronic control box 10, the first radiator 13 may be in contact with the driving board 12, which is not limited thereto.

The end of the first heat sink 13 located in the inner cavity 111 may include a plurality of second heat dissipation fins 132 disposed at intervals, and the second heat sink 14 may include a plurality of third heat dissipation fins 141 disposed at intervals. The third heat dissipation fins 141 and the second heat dissipation fins 132 may be parallel or intersected, and in this embodiment, the third heat dissipation fins 141 and the second heat dissipation fins 132 are substantially parallel, so as to facilitate better heat transfer between the two heat dissipation fins under the flowing of the airflow.

Referring to fig. 3 and 4, the first heat sink 13 may further include a first mounting plate 133, and the first and second heat radiating fins 131 and 132 may be mounted at 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.

The plurality of third heat radiating fins 141 of the second heat sink 14 may be directly mounted to the driving board 12, and the second heat sink 14 may also include a second mounting board (not shown) for mounting the third heat radiating fins 141, through which the second heat sink 14 may be mounted to the driving board 12. Of course, the second heat sink 14 may be mounted not to the driving board 12 but to the first casing 11 or other devices in the first casing 11, so that the second heat sink 14 and the driving board 12 can be in contact to realize heat transfer.

In order to accelerate the airflow velocity in the inner cavity 111, so that the first radiator 13 can collect more heat in the inner cavity 111 and cool energy in the outer machine main body 20 absorbed by the first radiator 13 can diffuse in the inner cavity 111, the first housing 11 is further formed with a first air inlet (not shown in the figure) and a first air outlet (not shown in the figure) which are communicated with 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 transmitted to the first radiator 13, and then the airflow flows out of the inner cavity 111 through the first air outlet. It can be appreciated that, during the process of flowing from the first air inlet to the first air outlet, at least part of heat in the inner cavity 111 can be taken away, so as to achieve a certain heat dissipation effect.

In an exemplary embodiment, the first air inlet and the first air outlet may be disposed at a position of the first housing 11 located outside the outer machine body 20, so that the air flow outside the outer machine body 20 may enter the first housing 11 and drive the heat in the first housing 11 to flow. The air flow outside the outer machine body 20 may directly enter the first housing 11 by wind power in nature, or the like, and the air flow outside the outer machine body 20 may also enter the first housing 11 by the cooling fan 15 disposed in the electronic control box 10, see fig. 2 and 3. When the cooling fan 15 is started, the air flow outside the outer machine body 20 can be driven to enter the inner cavity 111 through the first air inlet and flow out of the inner cavity 111 through the first air outlet, wherein the wind power of the cooling fan 15 and the opening and closing control are more flexible compared with the wind power in nature.

Further, 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 cool air in the outer machine body 20 into the inner cavity 111, the cooling fan 15 can blow the cool air on the first radiator 13 to the second radiator 14 and the driving board 12, so as to accelerate the cooling speed of the second radiator 14 and the driving board 12. The airflow path of the cooling fan 15 driving the inner cavity 111 may be a path as illustrated by an arrow in fig. 3, or may be another path, which is not limited thereto.

In another exemplary embodiment, the first air inlet and the first air outlet may be both located in the heat dissipation air channel 211. At this time, the airflow in the electronic control box 10 can be directly driven by the airflow in the external machine body 20, so that the cooling fan 15 is not needed to be additionally arranged in the electronic control box 10, and the volume and manufacturing cost of the electronic control box 10 can be reduced.

It should be noted that, if the first air inlet and the first air outlet are located in the heat dissipation air duct 211, the first air inlet, the first air outlet and the first opening 112 may be located on the same plate body of the first housing 11, and the first air inlet, the first air outlet and the first opening 112 may also be located on different plate bodies of the first housing 11, for example, in conjunction with fig. 1, the first housing 11 includes a first plate 1181 and a first peripheral side plate 1182 wound around the first plate 1181, the first peripheral side plate 1182 is connected with the first plate 1181, the first opening 112 may be disposed on the first plate 1181, and the first air inlet and the first air outlet may be provided with the first peripheral side plate 1182. Further, the first air inlet and the first air outlet may be disposed on opposite sides of the first peripheral side plate 1182, so that the airflow is smoother, which is not limited.

The first air inlet may be substantially located at the bottom of the first housing 11, and the first air outlet may be substantially located at the top of the first housing 11, which is not limited thereto. The first air inlet and the first air outlet may be provided with a dust screen to prevent dust wind impurities from entering the electronic control box 10.

In this embodiment, only a portion of the first radiator 13 may be disposed in the heat dissipation air duct 211 of the external unit main body 20, or a portion of the first radiator 13 and a portion of the first housing 11 may be disposed in the heat dissipation air duct 211 of the external unit main body 20. When the portion of the first housing 11 is disposed in the outer machine body 20, the portion of the first housing 11 disposed in the outer machine body 20 can be cooled directly under the effect of the cold air in the outer machine body 20, so that the cooling speed of the first housing 11 can be increased compared with the cooling speed of the first housing 11 which is entirely disposed outside the outer machine body 20 and only depends on the cold energy transferred by the first radiator 13.

Referring to fig. 1, the electronic control box 10 may further include a fixing member 117, where the fixing member 117 may be disposed outside the first housing 11 and connect the first housing 11 and the outer machine body 20. Further, the fixing member 117 may be connected to the first peripheral side plate 1182 of the first housing 11, where 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 near the first plate 1181, or disposed in a middle portion 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 far from the first plate 1181, so that the position of the fixing member 117 on the first peripheral side plate 1182 may be flexibly designed according to practical requirements.

The fixing member 117 may include a first fixing plate 1171 and a second fixing plate 1172 disposed at an included angle, where 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 outer machine body 20. Wherein, the included 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.

The first fixing plate 1171 and the first housing 11, and the second fixing plate 1172 and the outer machine body 20 may be connected by screws or the like, which is not limited thereto.

The electronic control box 10 may be provided with one fixing member 117, or may be provided with a plurality of fixing members 117, for example, two fixing members 117 may be provided on the electronic control box 10, and the two fixing members 117 are respectively located at two opposite sides of the first housing 11, so as to improve the assembly stability between the electronic control box 10 and the external machine main body 20.

Referring to fig. 3, the electronic control box 10 may further include a heater 16, where the heater 16 is disposed in the inner cavity 111. The heater 16 may be used to generate heat such that when the temperature within the interior cavity 111 is below the operating temperature of the devices within the interior cavity 111, the heater 16 may be controlled to generate heat to raise the temperature within the interior cavity 111 so that the devices can operate properly.

Referring to fig. 3, the electronic control box 10 may further include a mounting bracket 17, where the mounting bracket 17 is located in the inner cavity 111 and connected to the housing 11, and at least one of the driving 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 driving board 12, the first radiator 13, the second radiator 14, the cooling fan 15, and the heater 16 may be assembled with the mounting bracket 17 first, and then assembled in the first housing 11, so that the assembly is more convenient.

The mounting bracket 17 may include a second plate 171 and a second peripheral plate 172 wound around the periphery of the second plate 171, the second peripheral plate 172 is connected to the second plate 171, and at least one of the driving plate 12, the first heat sink 13, the second heat sink 14, the heat dissipation fan 15, and the heater 16 may be mounted on the second plate 171 and/or the second peripheral plate 172. Wherein 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.

Referring to fig. 1 and 2, the first housing 11 includes a case 113 and a cover 114, and the case 113 is formed with a first opening 112 and a third opening 115 opposite to the first opening 112; the cover 114 is disposed corresponding to the third opening 115 and is connected to the box 113, the cover 114 and the box 113 enclose an inner cavity 111, and the cover 114 is located outside the outer machine body 20. The cover 114 is located outside the outer machine body 20, so that when the electric control box 10 needs to be overhauled, the electric control box 10 can be overhauled directly outside the outer machine body 20, and compared with the prior art that the electric control box is placed in the outer machine body and needs to be taken out from the outer machine body during overhauling, the overhauling operation is more convenient.

The case 113 and the cover 114 may be detachably connected, rotatably connected, or the like, which is not limited thereto. If the case 113 and the cover 114 are detachably connected, the cover 114 may be removed from the case 113 when the electronic control box 10 is inspected, and the cover 114 and the case 113 may be assembled after the inspection is completed. If the box body 113 is rotatably connected with the cover body 114, when the electric control box 10 is overhauled, the cover body 114 can be rotated for a certain angle relative to the box body 113, so that devices in the inner cavity 111 can be exposed for overhauling operation without taking down the cover body 114. The case 113 and the cover 114 may be rotatably connected by a rotation member 119, and the rotation member 119 may be a hinge, etc., which is not limited thereto.

The inner cavity 111 can be formed in the box body 113, the inner cavity 111 can also comprise a first cavity 1111 and a second cavity 1112, the first cavity 1111 is formed in the box body 113, the second cavity 1112 is formed in the cover body 114, functional devices can be arranged in the first cavity 1111 and the second cavity 1112, namely, the box body 113 and the cover body 114 are internally provided with the functional devices, and compared with the inner cavity 111 which is only formed in the box body 113 and the functional devices are all arranged in the box body 113, the paving 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 paved, and overhaul is facilitated.

The driving plate 12, the first heat sink 13, the second heat sink 14, the heat dissipation fan 15, the heater 16, and the mounting bracket 17 may be disposed in the first chamber 1111, which is not limited thereto.

The device disposed in the first chamber 1111 may be defined as a first functional device, for example, the driving board 12 is provided with the first functional device, the device disposed in the second chamber 1112 may be defined as a second functional device, and the output power of the first functional device may be higher than that of the second functional device. Thus, when the electronic control box 10 is operated, the heat in the first chamber 1111 is higher than the heat in the second chamber 1112, and the first chamber 1111 is closer to the main body 20 than the second chamber 1112, so that the heat in the first chamber 1111 is easier to dissipate and cool than the heat in the second chamber 1112.

It should be noted that, if the case 113 is rotatably connected to the cover 114, referring to fig. 2 and 4, when the cover 114 is opened by rotating with respect to the case 113, the maximum opening angle between the cover 114 and the case 113 may be approximately 180 °, so that after the cover 114 and the case 113 are opened, the cover 114 and the case 113 are convenient for overhauling the case 113 and the functional devices in the cover 114. Of course, the maximum opening angle between the box 113 and the cover 114 may be greater than or equal to 90 ° and less than 180 ° or the like, which can achieve the effect of facilitating the maintenance of the operator, and in the embodiment of the present application, the maximum opening angle between the box 113 and the cover 114 is not particularly limited.

Because the box 113 and the cover 114 are provided with functional devices, when wiring, part of the circuit can cross the box 113 and the cover 114, and in order to avoid the problem that the circuit is extruded in the process of opening and closing the box 113 and the cover 114 relatively, referring to fig. 2, the box 113 and the cover 114 can be provided with a wire binding bridge 110. Thus, if the line spans the box 113 and the cover 114, the line can be fixed to the cable tie bridge 110 in the box 113 and the cover 114, and the bending margin of the portion is reserved, compared with the case where the line is not fixed by the cable tie bridge, the floating portion of the line is relatively smaller in the process of opening and closing the box 113 and the cover 114, so that the problem that the line is extruded by the box 113 and the cover 114 is not easy to occur. And, the arrangement of the wire binding bridge 110 is favorable for planning and arranging the wiring in the electric control box 10 and is favorable for overhauling.

It should be noted that, besides the rotatable connection between the box 113 and the cover 114, the box 113 may be rotatably connected with a rotating plate (not shown in the drawing) in the inner cavity 111, and the rotating plate is provided with a functional device, so that the functional device on the rotating plate can be spread when the rotating plate rotates relative to the box 113, which is convenient for an operator to overhaul. If a rotating plate is disposed in the inner cavity 111, the functional device on the rotating plate may be disposed on a side of the rotating plate away from the cover 114 and/or a side of the rotating plate close to the cover 114, and the functional device in the box 113 may be disposed on a side of the rotating plate away from the cover 114.

The functional device on the rotating plate may be defined as a third functional device, where the output power of the third functional device may be lower than that of the first functional device set on the box 113, so that the high heat generated during the operation of the first functional device may be timely and efficiently dissipated by the first radiator 13, and the cooling speed is faster.

Referring to fig. 2, the first housing 11 further includes an annular protrusion 116, where the annular protrusion 116 is disposed corresponding to the third opening 115 of the case 113, and the annular protrusion 116 is mounted on one of the case 113 and the cover 114 and protrudes with respect to the one of the case 113 and the cover 114, and the annular protrusion 116 is also in sealing connection with an inner wall of the other of the case 113 and the cover 114. Between the box body 113 and the cover 1114 which are relatively closed, the box body 113 and the cover 114 are tightly sealed, and the dustproof water discharging effect can be achieved.

Wherein, the annular protrusion 116 is also in sealing connection with the inner wall of the other of the box body 113 and the cover body 114, and may be: the annular protrusion 116 is also in sealing connection with the inner wall of the other of the case 113 and the cover 114 by a sealing ring 1161. The sealing ring 1161 may be attached to the annular protrusion 116 by bonding or the like and protrudes with respect to the annular protrusion 116, so that the sealing ring 1161 may be deformed by pressing when the case 113 and the cover 114 are closed, thereby exerting a better sealing effect.

Wherein, the annular protrusion 116 may be disposed on the cover 114, for example, the annular protrusion 116 and the cover 114 may be integrally formed, and a sealing ring 1161 may be disposed on a side of the annular protrusion 116 facing away from the cover 114. The annular protrusion 116 may also be disposed on the case 113, for example, the annular protrusion 116 and the case 113 may be integrally formed, and a sealing ring 1161 may be disposed on a side of the annular protrusion 116 facing away from the case 113.

In this embodiment, the annular protrusion 116 is disposed on the box body 113 and protrudes relative to the box body 113, when the box body 113 is covered with the cover body 114, the sealing ring 1161 on one side of the annular protrusion 116, which is away from the box body 113, can be abutted against the inner wall of the cover body 114 and be extruded by the inner wall of the cover body 114 to deform, so as to realize tightness when the box body 113 is covered with the cover body 114.

Specifically, if the second chamber 1112 is formed in the cover 114, the depth of the second chamber 1112 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 in the thickness direction of the electronic control box 10. Because the second chamber 1112 formed in the cover 114 has a shallower depth than the first chamber 1111 formed in the box 113, the annular protrusion 116 is formed on the box 113, so that the sealing ring 1161 on the annular protrusion 116 can extend into the second chamber 1112 when the box 113 is covered with the cover 114 and is in contact with the inner wall of the second chamber 1112, and the thickness of the annular protrusion 116 is smaller, and the opening and closing of the box 113 and the cover 114 are not easily affected by the annular protrusion 116 with smaller thickness.

Any sealing member such as a rubber sealing ring may be used as the sealing ring 1161, which is not limited thereto. The sealing ring 1161 can isolate rainwater from entering the inner cavity 111 from a gap between the box body 113 and the cover body 114, so that a good sealing effect is achieved.

The case 113 and the cover 114 may be fixed by bolts or the like after being closed, which is not limited.
