DETAILED DESCRIPTION

[0027] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0028] In the present disclosure, the orientation words such as "upper, lower" used herein generally refer to the use state of the heat dissipation structure. "Inner, outer" refers to the contour of the part itself, and "first direction" can refer to the X direction in the Figure 4 , "second direction" can refer to the Y direction in the Figure 4 , and "third direction" can refer to the Z direction in the Figure 4 . In addition, it should be noted that the terms "first, second" and the like are used to distinguish one element from another element, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.

[0029] In the related art, taking an air conditioner as an example, the temperature of the electric control device of the air conditioner outdoor unit is relatively high, and the electric control device needs to be cooled. The electric control device can be an electric control board. The heat dissipation structure is fixedly connected with the electric control board, and the electric control board is cooled by the heat dissipation structure. However, the heat dissipation structure in the related art is suspended and fixed on the electric control board through front and rear direction screws. When the heat dissipation structure fails, it is not convenient to disassemble and replace the electric control board.

[0030] like Figure 1-Figure 7 As shown, the first aspect of the present disclosure provides a heat dissipation structure, including a heat dissipation plate 1, at least one of the two side edges of the heat dissipation plate 1 in the first direction is provided with a limiting portion 11, the heat dissipation plate 1 is used to be detachably installed in the accommodating space 22 of the electric control bracket 2, and the limiting portion 11 is used to cooperate with the accommodating space 22 to limit the heat dissipation plate 1 in the first direction.

[0031] Through the above technical solution, a limiting portion 11 is provided on one of the two side edges of the heat sink 1 of the heat dissipation structure in the first direction, and the heat sink 1 can be detachably installed in the accommodating space 22 of the electric control bracket 2. The limiting portion 11 cooperates with the accommodating space 22 to limit the heat sink 1 in the first direction, thereby avoiding excessive position displacement of the heat sink 1 in the first direction, facilitating the disassembly and assembly of the heat sink 1 and the electric control bracket 2. When the heat sink 1 fails, it can be easily disassembled and separated from the accommodating space 22 of the electric control bracket 2, thereby improving maintenance efficiency.

[0032] In some practicable embodiments, in order to facilitate limiting the position of the heat sink 1 in the first direction through the cooperation between the limiting portion 11 and the accommodating space 22 of the electric control bracket 2 , the limiting portion 11 is a first groove 12 or a first protrusion.

[0033] Optionally, the limiting portion 11 is a first groove 12, with both sides of the heat sink 1 in the first direction concave toward the center. The first groove 12 extends in the second direction and reaches both ends of the heat sink 1 in the second direction. In this case, to facilitate engagement with the first groove 12, a raised portion is provided within the accommodating space 22 of the electronic control bracket 2, adapted to engage with the first groove 12. Thus, the engagement of the groove and the raised portion can restrict the position of the heat sink 1 in the first direction. Of course, the engagement of the raised portion and the groove also serves as a guide, facilitating removal of the heat sink 1 from the accommodating space 22 in the second direction.

[0034] In some embodiments, to facilitate heat dissipation, the heat sink 1 is provided with a second groove 13 on its rear end surface in the third direction. The second groove 13 extends along the second direction and extends to both ends of the heat sink 1 in the second direction. The provision of the second groove 13 increases the heat dissipation area, thereby facilitating rapid heat dissipation from the heat sink 1. Of course, the second groove 13 also serves as a diversion device. If moisture flows from the upper portion of the electronic control bracket 2 onto the heat sink 1, the moisture can be quickly diverted through the second groove 13, preventing failure of the heat sink 1 or the circuit board.

[0035] It is understandable that there are multiple second grooves 13, and the multiple second grooves 13 are arranged at intervals along the first direction. In this way, the heat dissipation area can be further increased and the heat dissipation efficiency can be improved.

[0036] In some implementable manners, in order to facilitate heat dissipation, the heat dissipation structure further comprises a heat dissipation pipe 3 and a mounting seat 4, the mounting seat 4 and the heat dissipation plate 1 are arranged in the second direction, the heat dissipation pipe 3 is arranged between the mounting seat 4 and the heat dissipation plate 1, the mounting seat 4, the heat dissipation pipe 3 and the heat dissipation plate 1 are fixedly connected through fasteners, the heat dissipation pipe 3 can be a copper pipe, the copper pipe is filled with circulating refrigerant, the heat dissipation pipe 3 comprises a U-shaped section, the straight section of the U-shaped section is clamped and fixed by the mounting seat 4 and the heat dissipation plate 1, in order to facilitate cooperation with the straight section of the U-shaped section, the mounting seat 4 and the heat dissipation plate 1 are provided with arc-shaped mounting grooves on the opposite sides in the second direction, and corresponding mounting holes are further provided on the mounting seat 4 and the heat dissipation plate 1, the U-shaped section of the copper pipe is first arranged in the mounting groove between the mounting seat 4 and the heat dissipation plate 1, and then the mounting seat 4, the heat dissipation pipe 3 and the heat dissipation plate 1 are fixedly connected through the fasteners penetrating through the corresponding mounting holes. In addition, in order to facilitate heat dissipation, the mounting seat 4 can be an aluminum plate. The mounting seat 4 can be mounted on the electric control support 2 or mounted on the electric control board.

[0037] Of course, the straight section in the U-shaped section of the heat dissipation pipe 3 fixedly connected with the mounting seat 4 and the heat dissipation plate 1 is illustrative, in other embodiments, the arc-shaped section and at least part of the straight section in the U-shaped section of the heat dissipation pipe 3 can be arranged between the mounting seat 4 and the heat dissipation plate 1, and fixed through the mounting holes of the mounting seat 4 and the heat dissipation plate 1. Thus, by circulating refrigerant flowing in the heat dissipation pipe 3, the heat dissipation efficiency can be further improved.

[0038] The second aspect of the present disclosure provides a heat dissipation assembly comprising the heat dissipation structure and the electric control support 2 fixing the heat dissipation structure, the electric control support 2 comprises a support body 21, the support body 21 can be an aluminum plate, the support body 21 is provided with a containing space 22 containing the heat dissipation structure, and the heat dissipation structure is detachably arranged in the containing space 22. Thus, by arranging the containing space 22 detachably containing the heat dissipation plate 1 on the support body 21 of the electric control support 2 in the heat dissipation assembly, the heat dissipation plate 1 can be detachably arranged on the electric control support 2, replacing the mode that the heat dissipation plate 1 is directly connected with the electric control board in the related art, so that when the heat dissipation plate 1 fails, the heat dissipation plate 1 can be easily detached and separated from the containing space 22 of the electric control support 2, improving the maintenance efficiency.

[0039] In some implementable manners, the containing space 22 comprises a recessed portion 23 recessed in the third direction, first limiting members 24 cooperating with the limiting portions 11 are arranged in the recessed portion 23 and on both sides of the heat dissipation plate 1 in the first direction, and the two first limiting members 24 are used for limiting the heat dissipation plate 1 in the first direction.

[0040] In some possible implementation manners, the heat dissipation plate 1 is detachably accommodated in the accommodation space 22, wherein the electric control support 2 can be an aluminum plate, the accommodation space 22 can include a recessed portion 23 recessed in the third direction, the recessed portion 23 is provided with a connecting hole, and the heat dissipation plate 1 is provided with a matching hole, and a fastener passes through the connecting hole of the recessed portion 23 and the matching hole of the heat dissipation plate 1 to detachably accommodate the heat dissipation plate 1 in the accommodation space 22.

[0041] It can be understood that the detachable connection manner of the heat dissipation plate 1 and the accommodation space 22 described above is illustrative, and in some possible implementation manners, a clamping portion can be arranged on the recessed portion 23, and a connecting portion can be arranged on the heat dissipation plate 1, and the connecting portion and the clamping portion of the heat dissipation plate 1 are matched to detachably arrange the heat dissipation plate 1 in the accommodation space 22.

[0042] In order to limit the heat dissipation plate 1 in the first direction, in some possible implementation manners, first limiting members 24 are arranged on opposite sides of the recessed portion 23 in the first direction, and the first limiting members 24 are used for limiting the heat dissipation plate 1 in the first direction. Wherein, the two first limiting members 24 are both baffle plates 25, the opposite sides of the two baffle plates 25 in the first direction are both provided with a matching portion 26, the limiting portion 11 is configured as a first groove 12, and the matching portion 26 is configured as a second protrusion matched with the first groove 12. Thus, a limiting space is formed between the two baffle plates 25 and the bottom wall of the recessed portion 23 to limit the heat dissipation plate 1 in the first direction, so as to reduce the deviation of the heat dissipation plate 1 in the first direction, and facilitate the disassembly and assembly of the heat dissipation plate 1 and the accommodation space 22. That is, the limiting space formed between the two baffle plates 25 and the bottom wall of the recessed portion 23 can facilitate the alignment of the matching hole on the heat dissipation plate 1 and the connecting hole on the recessed portion 23, and facilitate the fastener passing through the matching hole and the connecting hole to fix the heat dissipation plate 1 in the recessed portion 23.

[0043] In some possible implementation manners, the baffle plate 25 can be independently arranged, that is, the baffle plate 25 can be fixed on the recessed portion 23 by welding or gluing, of course, the baffle plate 25 can also be integrally formed with the electric control support 2, for example, the baffle plate 25 is formed by turning up the bottom wall of part of the recessed portion 23 in the third direction, so as to improve the structural strength between the baffle plate 25 and the electric control support 2, and facilitate processing and forming.

[0044] In some possible implementation manners, the number of baffle plates 25 can be multiple, and each baffle plate 25 is located on the two sides of the heat dissipation plate 1 in the first direction, for example, the baffle plate 25 can be four, and each two baffle plates 25 are arranged in a group, and the two groups of baffle plates 25 are arranged at intervals in the second direction, so as to limit the heat dissipation plate 1 in the first direction by the two groups of baffle plates 25.

[0045] In addition, in order to facilitate the disassembly and assembly of the heat sink 1 from the accommodating space 22, in some feasible embodiments, the accommodating space 22 also includes two openings 27, and the two openings 27 are respectively located at the two ends of the accommodating space 22 in the second direction. An opening 27 is respectively set at both ends of the second direction, and the projection of the opening 27 in the third direction is a rectangle. The diameter of the opening 27 is larger than the width of the heat sink 1, so that the heat sink 1 can be easily inserted into the accommodating space 22 through any one of the openings 27.

[0046] The bracket body 21 further includes a second limiting member 28 . The second limiting member 28 is located at the lower portion of the accommodating space 11 and is used to limit the heat dissipation plate 1 in the second direction.

[0047] In some feasible embodiments, the bracket body 21 also includes a second limit member 28, which is located at the lower part of the accommodating space 22 and is used to limit the heat sink 1 in the second direction. The second limit member 28 can be a limit plate extending along the first direction, and the limit plate can be integrally formed with the bottom wall of the accommodating space 22. For example, the limit plate can also be formed by flanging the bottom wall of the accommodating space 22 in the third direction in the direction away from the bottom wall, so that when the heat sink 1 is installed in the accommodating space 22, the heat sink 1 can be limited in the second direction, that is, in the vertical direction, by the second limit member 28. In this way, in conjunction with the two baffles 25 to limit the position in the first direction, the heat sink 1 has smaller movable space, which makes it easier for the heat sink 1 to be installed in the accommodating space 22.

[0048] Of course, the above-mentioned second limiting member 28 is constructed as a limiting plate extending along the second direction and is integrally formed with the bottom wall of the accommodating space 22. This is schematic. In other embodiments, the second limiting member 28 is constructed as a limiting plate, and the limiting plate can be fixedly connected to the bottom wall of the electric control bracket 2 by welding.

[0049] The bracket body 21 further includes at least one support member 29 . The support member 29 is disposed above the second limiting member 28 .

[0050] In some embodiments, in order to facilitate the removal of the heat sink 1 from the accommodating space 22, the bracket body 21 also includes at least one support member 29, which is arranged above the second limit member 28. The support member 29 can be constructed as a support protrusion on the bottom wall of the accommodating space 22 facing away from the bottom wall in the second direction. The number of support protrusions can be selected according to the specific size of the heat sink 1. For example, in this embodiment, the number of support protrusions is two, and the two support protrusions are spaced apart in the second direction. Therefore, when the heat sink 1 is installed in the accommodating space 22, the bottom surface of the heat sink 1 contacts the support protrusions, rather than the bottom surface of the heat sink 1 as a whole abutting against the bottom wall of the accommodating space 22, thereby reducing the friction between the heat sink 1 and the bottom wall of the accommodating space 22, making it easier for the heat sink 1 to be removed from the accommodating space 22.

[0051] A third aspect of the present disclosure provides an air conditioner outdoor unit comprising the aforementioned electronic control bracket. The provision of the electronic control bracket 2 facilitates the detachable mounting of the heat sink 1 thereon. This facilitates easy removal and installation of the heat sink 1 in the event of a malfunction, improving maintenance efficiency. It will be appreciated that the aforementioned air conditioner outdoor unit possesses all the benefits of the aforementioned electronic control bracket, and further details will not be provided here.

[0052] The fourth aspect of the present disclosure may further provide an air conditioner, comprising the above-mentioned air conditioner outdoor unit. The above-mentioned air conditioner has all the beneficial effects of the air conditioner outdoor unit, which will not be described in detail here.

[0053] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0055] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
