It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0029] like Figure 1 As shown, in one aspect, this application provides an integrated heat sink 1, which includes a heat sink body 11 and a plurality of heat-generating power devices 12, which can improve assembly efficiency and installation alignment accuracy, thereby improving the heat dissipation effect of the heat sink on the heat-generating power devices 12.

[0030] Here, multiple heat-generating power devices 12 are respectively mounted on the heat sink body 11, with each heat-generating power device 12 aligned with the heat sink body 11. The heat-generating power device 12 has an insulating side and a conductive connection side 121 arranged opposite to each other. The insulating side is attached and fixed to the heat sink body 11 to form a good thermally conductive connection, while the conductive connection side 121 is used for conductive connection with the circuit board.

[0031] The integrated heat sink 1 provided in this application embodiment pre-installs the heat-generating power device 12 on the heat sink body 11, making it easy to install and align the heat-generating power device 12 and the heat sink body 11, improving the installation and alignment accuracy of the heat-generating power device 12 and the heat sink body 11, thereby improving the heat dissipation effect of the heat sink on the heat-generating power device 12; when fixing the integrated heat sink 1 and the main control circuit board 3, the conductive connection side 121 of the heat-generating power device 12 can be directly aligned and conductively connected to the main control circuit board 3, effectively improving assembly efficiency.

[0032] In some embodiments, the heat sink body 11 may have a heat sink plate 111 and a plurality of heat sink fins 112. The plurality of heat sink fins 112 are respectively formed on one side surface of the heat sink plate 111, and a plurality of heat-generating power devices 12 are respectively disposed on the side surface of the heat sink plate 111 away from the heat sink fins 112. Thus, the heat generated by the heat-generating power devices 12 during operation can be conducted through the insulating side to the heat sink plate 111, and from the heat sink plate 111 to the heat sink fins 112, and then dissipated into the air by the heat sink fins 112, thereby improving the heat dissipation performance of the heat sink body 11.

[0033] The connection method between the heating power device 12 and the heat sink body 11 can be determined according to actual needs, and can be such as bonding, threaded fastening, etc., which are not limited in this embodiment. In some embodiments, the integrated heat sink 1 may include a thermally conductive adhesive layer. The thermally conductive adhesive layer is disposed between the insulating side of the heating power device 12 and the heat sink body 11, and is used to bond and fix the heating power device 12 and the heat sink body 11. The thermally conductive adhesive layer can be made of an adhesive material with high thermal conductivity, such as thermally conductive silicone, which has high bonding performance and can reliably bond and fix the heating power device 12 and the heat sink body 11, and can efficiently conduct the heat generated by the heating power device 12 to the heat sink body 11, ensuring a better heat dissipation effect.

[0034] like Figure 2As shown, in some embodiments, a plurality of positioning mounting portions 113 are provided on one side surface of the heat sink body 11, and a plurality of heating power devices 12 are positioned and mounted one-to-one with the plurality of positioning mounting portions 113. In this way, the plurality of heating power devices 12 can be positioned and mounted in preset positions, thereby ensuring that each heating power device 12 on the integrated heat sink 1 can be accurately aligned with the circuit board and electrically connected. The type of positioning mounting portion 113 can be determined according to actual needs, and can be set as, for example, positioning groove, positioning rib, etc., which is not limited in this embodiment. For example, the positioning mounting portion 113 can be set according to the shape of the corresponding heating power device 12 to ensure the shape correspondence between the positioning mounting portion 113 and the heating power device 12.

[0035] like Figures 1 to 5 As shown, in a second aspect, embodiments of this application provide an electrical control box, which includes a box body 2, an integrated heat sink 1, and a main control circuit board 3. The box body 2 has a mounting groove 21, and the integrated heat sink 1 is embedded in the mounting groove 21, with the side of the heat sink body 11 furthest from the heat-generating power device 12 facing the bottom of the mounting groove 21. The main control circuit board 3 is disposed on the side of the integrated heat sink 1 furthest from the bottom of the mounting groove 21, and the conductive connection side 121 of the heat-generating power device 12 is soldered and fixed to the main control circuit board 3.

[0036] Compared with related technologies, the electrical control box provided in this application first pre-installs the heat-generating power device 12 onto the heat sink body 11 to form an integrated heat sink 1. Then, the integrated heat sink 1 is installed into the mounting slot 21 of the electrical control box body 2. Subsequently, the main control circuit board 3 is installed on the side of the integrated heat sink 1 away from the bottom of the mounting slot 21. The conductive connection side 121 of the heat-generating power device 12 and the main control circuit board 3 are welded and fixed together. This allows for the rapid completion of the installation of the electrical control box body 2 and its various components, thereby improving assembly efficiency and installation alignment accuracy, and enhancing the heat dissipation effect of the heat sink on the heat-generating power device 12.

[0037] In some embodiments, the mounting groove 21 has a flange 22 at its opening. When the integrated heat sink 1 is embedded in the mounting groove 21, the flange 22 abuts against the side surface of the heat sink body 11 facing the opening of the mounting groove 21 to reliably fix the integrated heat sink 1 in the mounting groove 21 and prevent the integrated heat sink 1 from accidentally coming out of the mounting groove 21. In addition, the flange 22 also serves to support the main control circuit board 3.

[0038] In some examples, the flange 22 may have a first through hole 221, the radiator body 11 may have a first fastening hole 1111, and the main control circuit board 3 may have a second through hole 31. The first fastening hole 1111, the first through hole 221, and the second through hole 31 are correspondingly arranged. Fasteners pass through the second through hole 31 and the first through hole 221 sequentially and are then fastened into the first fastening hole 1111, so that the integrated radiator 1, the flange 22, and the main control circuit board 3 are sequentially stacked and fixed. Here, the type of the first fastening hole 1111 and the fastener can be determined according to actual needs, and combinations such as pin holes and fastening pins, threaded holes and bolts can be used. This application embodiment does not limit this. In this way, a single fastener can be used to fix the main control circuit board 3, the integrated radiator 1, and the electrical control box 2, reducing the number of fasteners required and the number of fastening steps, thereby reducing installation costs and improving installation efficiency.

[0039] Here, the number of the first fastening hole 1111, the first through hole 221, and the second through hole 31 can be determined according to actual needs, and there can be one or more. This application embodiment does not limit this. The first fastening hole 1111, the first through hole 221, and the second through hole 31 are provided in a one-to-one correspondence so as to be assembled with the fastener.

[0040] In some embodiments, the electrical control box 2 may be provided with a first positioning part 23, and the main control circuit board 3 may be provided with a second positioning part 32. One of the first positioning part 23 and the second positioning part 32 is a positioning post, and the other is a positioning hole; the positioning post and the positioning hole are inserted into each other to position the main control circuit board 3 on the electrical control box 2. By providing the first positioning part 23 and the second positioning part 32, rapid positioning between the electrical control box 2 and the main control circuit board 3 can be achieved, further improving assembly efficiency.

[0041] In some examples, the electrical control box 2 may be provided with multiple second fastening holes 25 and multiple first positioning parts 23, and the main control circuit board 3 may be provided with multiple third through holes 34 and multiple second positioning parts 32. The second fastening holes 25 and the third through holes 34 are arranged in a one-to-one correspondence, and the first positioning parts 23 and the second positioning parts 32 are inserted into each other in a one-to-one correspondence. The multiple third through holes 34 and the multiple second positioning parts 32 are arranged alternately and spaced along the circumference of the main control circuit board 3, and the fastener passes through the third through hole 34 and is fastened to the second fastening hole 25. For example, the main control circuit board 3 can be a rectangular board, and it can be provided with two third through holes 34 and two second positioning parts 32. The two third through holes 34 can be arranged diagonally along one diagonal of the rectangular board, and the two second positioning parts 32 can be arranged diagonally along the other diagonal of the rectangular board. Correspondingly, the electrical control box 2 can be provided with two second fastening holes 25 and two first positioning parts 23. Each fastener passes through one third through hole 34 and is fastened to the second fastening hole 25. By alternately arranging multiple third through holes 34 and multiple second positioning parts 32 along the circumference of the main control circuit board 3, the purpose of rapid alignment and reliable fastening can be achieved better.

[0042] The structure of the conductive connection side 121 can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the conductive connection side 121 may include conductive pins, and the main control circuit board 3 is provided with pin holes 33. The conductive pins pass through the pin holes 33 and are soldered and fixed to the main control circuit board 3. In this way, the heating power device 12 can be conductively connected to the main control circuit board 3 through the conductive pins.

[0043] In some embodiments, the groove opening of the mounting slot 21 may be provided with a snap-fit ​​portion 24. When the integrated heat sink 1 is embedded in the mounting slot 21, the snap-fit ​​portion 24 engages with the side surface of the heat sink body 11 facing the groove opening of the mounting slot 21, so as to reliably fix the integrated heat sink 1 in the mounting slot 21 and prevent the integrated heat sink 1 from accidentally falling out of the mounting slot 21.

[0044] In some embodiments, the electrical control box 2 may be provided with support ribs 26, which are used to support the main control circuit board 3. The number of support ribs 26 can be determined according to actual needs, and may be one or more, which is not limited in this embodiment.

[0045] Thirdly, this application provides an air conditioner that includes the electrical control box provided in any of the above embodiments. The type of air conditioner can be determined according to actual needs, and can include types such as wall-mounted air conditioners, cabinet air conditioners, and window air conditioners; this application does not limit this type. The air conditioner provided in this application, having the aforementioned electrical control box, can improve assembly efficiency and installation alignment accuracy, thereby improving the heat dissipation effect of the radiator on the heat-generating power device 12.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.

Therefore, the content of this specification should not be construed as a limitation of this application.
