Detailed Embodiments

[0034] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model.

[0036] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0037] In order to make the purpose, technical solution and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0038] Please refer to Figures 1 to 6 As shown, an embodiment of the present utility model provides a bracket adapted to mount a power device between a circuit board and a heat sink, including a bracket body 1 and an annular frame 2. Specifically, the bracket body 1 is disposed on the circuit board, that is, above the circuit board. The bracket body 1 is used to support the power device so that the power device is in contact with the heat sink. Thus, the power device can be lifted, so that the power device can abut against the heat sink to ensure that the heat of the power device can be dissipated in time, and further ensure that the power device can work normally.

[0039] As Figure 1 shown, the annular frame 2 is connected to the bracket body 1 to make the bracket a whole. The annular frame 2 is disposed between the circuit board and the heat sink, and the annular frame 2 is disposed around the circumference of the bracket body 1 to form a covering space surrounding the power device. That is to say, the annular frame 2 surrounds the power device, which is equivalent to constructing a closed space between the circuit board and the heat sink. In this way, it is not easy for crawlers, sundries, etc. to enter the inside of the annular frame 2, and thus they cannot reach the position of the high-temperature power device.

[0040] With such a setting, the power device can be fixed on the circuit board through the bracket body 1 and kept in contact with the heat sink for heat dissipation. At the same time, the power device can be surrounded by the annular frame 2 to form a fully enclosed design, thereby reducing the entry of insects, etc. into the position of the power device, effectively playing a protective role, preventing the occurrence of circuit board short-circuit phenomena, and ensuring the reliable operation of the outdoor unit of the air conditioner. It should be noted that, taking the placement position of the bracket as shown in Figure 1 the figure, the up and down directions in the figure are the indicated up and down orientations.

[0041] In the prior art, in order to maintain the overall aesthetics of a building, the outdoor unit of an air conditioner is generally installed inside a grille. However, in high-temperature weather in summer, due to the high-temperature environment of the power devices, the heat dissipation effect is not ideal, and the high-temperature protection shutdown phenomenon is likely to occur, affecting the user experience.

[0042] Therefore, further, in the embodiment of the present utility model, as Figure 4 shown, the bracket further includes at least two heat dissipation holes 3, and the heat dissipation holes 3 are spaced apart from each other on the annular frame 2. Specifically, as Figure 6 shown, the heat dissipation holes 3 can be designed as long holes. It should be noted that the shape, quantity, and spacing of the heat dissipation holes 3 can be specifically determined according to actual design requirements. Since a number of heat dissipation holes 3 are arranged on the annular frame 2, an air flow channel communicating the internal and external environments of the bracket is formed. Generally, the outdoor unit of an air conditioner is provided with a fan and a condenser. Under the action of the fan, the high-temperature gas around the power devices can be taken away in time and discharged to the outside. Moreover, the low-temperature gas at the condenser can also be introduced through the heat dissipation holes 3 to achieve the purpose of cooling the power devices.

[0043] With such a setting, by adding multiple heat dissipation holes 3, the air circulation between the enclosed space formed by the annular frame 2 and the external environment can be further promoted, the heat dissipation method at the position of the power devices is optimized, which is beneficial to quickly take away the heat generated by the power devices, realize the function of rapid heat dissipation of the power module, improve the heat dissipation condition of the outdoor unit of the air conditioner under high-temperature conditions, ensure the reliable operation of the outdoor unit of the air conditioner, and enhance the user experience.

[0044] In an alternative embodiment of the present utility model, the bracket further includes a plurality of limit clamping portions 4, as Figure 1 shown, each of the limit clamping portions 4 protrudes from the side of the bracket body 1 close to the radiator. And the limit clamping portions 4 are spaced apart along the circumferential direction of the power devices, and the limit clamping portions 4 are used for limiting and fixing the power devices. Specifically, the limit clamping portions 4 can be designed in the form of claws, and a number of claws are arranged around each power device to achieve the positioning and installation of the power devices. With such a setting, by arranging the limit clamping portions 4, it is convenient to quickly install and position the power devices, improving the production efficiency. In addition, the adjacent power devices can be separated from each other by the limit clamping portions 4, and the heat dissipation effect is good.

[0045] As an alternative embodiment of the present utility model, the top surface 21 of the annular frame 2 is in close contact with the heat dissipation surface of the radiator. With such a setting, a sealed connection between the bracket and the radiator can be achieved, effectively preventing insects. In addition, the radiator is not only in direct contact with the power devices, but also indirectly in contact with the power devices through the annular frame 2, thereby further expanding the heat dissipation area and effectively improving the heat dissipation effect. It can be understood that the structural form of the top surface 21 of the annular frame 2 should be consistent with the structural form of the heat dissipation surface of the radiator. For example, asFigure 2 As shown, the top surface 21 of the annular frame 2 is adaptively designed in the form of a stepped structure.

[0046] In a specific embodiment of the present utility model, the bracket main body 1 is provided with at least one mounting portion 5. The mounting portion 5 is located on the side of the bracket main body 1 close to the radiator. The power device is arranged on the mounting portion 5. The power device and the mounting portion 5 are correspondingly provided with first mounting holes 6 for inserting fasteners. It can be understood that the number of the mounting portions 5 needs to be correspondingly determined according to the number of the power devices. For example, as Figure 3 shown, there are four mounting portions 5, and multiple different power devices can be respectively mounted. Bolts can be selected as the fasteners, so that the power device can be fixedly mounted on the bracket main body 1 through the bolts. Correspondingly, through holes opposite to the first mounting holes 6 are provided on the circuit board for mounting and fixing the power device and the bracket. It should be noted that the number, position, etc. of the first mounting holes 6 can be specifically designed according to the mounting requirements of the power device.

[0047] In an alternative embodiment of the present utility model, as Figure 1 shown, the annular frame 2 is provided with at least one positioning post 7. The positioning post 7 and the radiator are correspondingly provided with second mounting holes 9 for inserting positioning members 8. Specifically, positioning pins can be selected as the positioning members 8, and the positioning pins are respectively inserted into the second mounting holes 9 on the bracket and the radiator. With such a setting, the quick alignment and installation of the radiator can be realized through the positioning member 8, and the assembly efficiency can be improved.

[0048] As an alternative embodiment of the present utility model, as Figure 5 shown, the bracket main body 1 is provided with at least one protruding portion 10. The protruding portion 10 protrudes from the side of the bracket main body 1 close to the circuit board, and the protruding portion 10 abuts against the circuit board. Since the bracket main body 1 needs to lift the power device so that the power device is always in contact with the radiator, there is a certain gap between the bracket main body 1 and the circuit board. By providing a plurality of protruding portions 10, the bracket main body 1 can be made to abut against the circuit board, and the support stability of the bracket main body 1 can be improved. In addition, a certain heat dissipation space can be left, which is beneficial to the rapid heat dissipation of the power device.

[0049] In a specific embodiment of the present utility model, the bracket main body 1 and the annular frame 2 are of an integrally formed structure. Specifically, the materials of the bracket main body 1 and the annular frame 2 can be selected as plastics and integrally injection molded. With such a setting, it is convenient for processing and manufacturing, the production efficiency is improved, and the overall structural strength is high, and the forming quality and processing precision are high. Of course, in other embodiments, the materials of the bracket main body 1 and the annular frame 2 include but are not limited to plastics, and can also be metals, etc. If it is metal, insulation treatment should be done to prevent short circuit.

[0051] The utility model embodiment also provides an electrical box suitable for installation in an air conditioner outdoor unit, including a circuit board, a radiator, a power device and a bracket. Specifically, the bracket is configured as a bracket as in the above-mentioned embodiments. The radiator is disposed above the circuit board, the power device is disposed on the bracket, and the bracket is disposed between the circuit board and the radiator. In this configuration, the power device can be fixed on the circuit board through the bracket body 1, and keep in contact with the radiator for heat dissipation. At the same time, the power device can be surrounded on all sides by the annular frame 2 to form a fully surrounded design, thereby reducing the entry of insects and the like into the power device position, effectively playing a protective role, preventing the occurrence of circuit board short circuits, and ensuring the reliable operation of the air conditioner outdoor unit. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned bracket, so it will not be repeated here.

[0052] The air-conditioning outdoor unit provided by the present invention is described below. The air-conditioning outdoor unit described below and the electrical appliance box described above can be referred to each other.

[0053] The embodiment of the utility model also provides an air-conditioning outdoor unit, including a housing and an electrical box. Specifically, the electrical box is configured as the electrical box in the above embodiment, and the electrical box is disposed in the housing. With such a configuration, the power device can be fixed on the circuit board through the bracket body 1, and keep in contact with the radiator for heat dissipation, while the power device can be surrounded by the annular frame 2 to form a fully surrounded design, thereby reducing the entry of insects and the like into the power device position, effectively playing a protective role, preventing the occurrence of circuit board short circuits, and ensuring the reliable operation of the air-conditioning outdoor unit.
