[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] See also Figure 1 to Figure 13 The embodiment of the utility model provides a driving board installation structure, including a circuit board 2, a bracket 3 and a plate-shaped first radiator 1, wherein the circuit board 2 is the driving board body, the bracket 3 is used to carry the circuit board 2, and the circuit board 2 can be installed on the first radiator 1, and the first radiator 1 is used to dissipate heat for the circuit board 2. The first radiator 1 has a first surface and a second surface opposite to each other, and the first surface is provided with a blind hole-type first threaded hole 13, that is, the first threaded hole 13 does not penetrate the first radiator 1, the bracket 3 is fixed to the first surface of the first radiator 1 by a first screw 71 matched with the first threaded hole 13, and the circuit board 2 is fixed to the bracket 3 by a second screw 72, so that the circuit board 2, the bracket 3 and the first radiator 1 are connected together to form a driving board installation structure. The bracket 3 is provided with a hollow area 31, and the circuit board 2 is provided with a power device that contacts the first surface of the first radiator 1 through the hollow area 31, that is, the circuit board 2 is provided with a power device at least at a position corresponding to the hollow area 31 of the bracket 3, and the power device contacts the first surface of the first radiator 1, and the heat generated by the power device is conducted to the first radiator 1 to achieve heat dissipation. When the drive board installation structure of the utility model is applied to a product (such as an air conditioner controller), the second surface of the first radiator 1 faces the outside of the product, so as to dissipate heat. Since the first threaded hole 13 on the first radiator 1 used to connect the bracket 3 is a blind hole structure that does not penetrate the first radiator 1, it prevents external water of the product from entering the side of the circuit board 2 through the screw fixing hole, thereby achieving a waterproof function. It can be seen that the drive board installation structure of the utility model can well take into account the heat dissipation and waterproofing of the drive board.

[0043] In a preferred embodiment, the first radiator 1 is configured as a hollow structure, and a refrigerant is filled in the inner cavity of the first radiator 1. The refrigerant radiator has a strong heat dissipation effect, so the utility model takes it as a preferred embodiment. It should be noted that when the first radiator 1 is a hollow structure, the blind hole type first threaded hole 13 is not connected to the inner cavity of the first radiator 1. Figure 1 , Figure 3 and Figure 8 As shown, in order to further improve the waterproof performance, a circle of protective wall 33 can be provided on the side of the bracket 3 facing away from the first radiator 1. The protective wall 33 encloses an installation area that matches the contour shape of the circuit board 2, that is, the size of the circuit board 2 is consistent with the installation area enclosed by the protective wall 33, so that the circuit board 2 can be placed flat in the installation area, and the protective wall 33 is blocked at the edge of the circuit board 2 to play a water-blocking and protective role.

[0044] like Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.11 As shown, in order to further improve the waterproof performance, a circle of water retaining edge 34 can be provided on the side of the bracket 3 facing the first radiator 1, and the hollow area 31 is located in the waterproof area surrounded by the water retaining edge 34, and the first surface of the first radiator 1 is provided with an escape groove 12 that is plugged and matched with the water retaining edge 34. When installing the bracket 3 to the first radiator 1, the water retaining edge 34 of the bracket 3 is inserted into the escape groove 12 of the first radiator 1, and then the first screw 71 is screwed into the first threaded hole 13 on the first radiator 1 through the fifth mounting hole 32 on the bracket 3, so that the bracket 3 is fixedly connected to the first radiator 1. Since a circle of water retaining edge 34 that surrounds the hollow area 31 is provided on the side of the bracket 3 facing the first radiator 1, it is possible to prevent water from entering the area where the power device contacts the first radiator 1 from the gap between the bracket 3 and the first radiator 1, thereby achieving a waterproof effect. In order to improve the tightness between the bracket 3 and the first radiator 1, the bracket 3 is usually set as a plastic part.

[0045] In order to facilitate the positioning and installation of the bracket 3 on the first radiator 1, a positioning column 35 located in the waterproof area surrounded by the water retaining edge 34 may be provided on the side of the bracket 3 facing the first radiator 1, and a positioning blind hole 14 plugged with the positioning column 35 is provided on the first surface of the first radiator 1. The positioning blind hole 14 does not penetrate the first radiator 1, and is not connected to the inner cavity of the first radiator 1 when the first radiator 1 is a hollow structure. Specifically, the positioning columns 35 are usually provided in two or more. In order to improve assembly efficiency, the hollow area 31 may be provided with convex or concave corners at local positions for fool-proofing. Fig.10 and Fig.11 As shown, in this embodiment, the hollow area 31 is set to be a rectangle with missing corners, which can play an anti-mistake effect and ensure the correct installation of the bracket 3 and other components.

[0046] like Figure 1~Figure 4 As shown, in a preferred embodiment, the edge of the first radiator 1 is provided with a plurality of first mounting holes 11 distributed around the bracket 3, and the drive board mounting structure includes a frame-shaped waterproof foam 4 fixed to the second surface of the first radiator 1, and the waterproof foam 4 is provided with second mounting holes (not marked in the figure) corresponding one to one with the first mounting holes 11. The first mounting holes 11 are used to mount the first radiator 1 to the product to which the drive board mounting structure is applied, for example, to the housing of an air-conditioning controller. By providing the waterproof foam 4, the risk of water ingress can be reduced. Specifically, the side of the waterproof foam 4 facing the first radiator 1 is usually provided with a backing adhesive, and the waterproof foam 4 can be adhered to the second surface of the first radiator 1 by using the backing adhesive.

[0047] like Figure 2 , Figure 3 , Fig.12 and Fig.13 As shown, in a preferred embodiment, the drive board mounting structure includes a second heat sink, a second blind-hole type threaded hole 15 is provided on the second surface of the first heat sink 1, and the second heat sink is fixed to the second surface of the first heat sink 1 by a third screw 73 matched with the second threaded hole 15. The heat generated by the power device on the circuit board 2 is first conducted to the first heat sink 1, and then the first heat sink 1 conducts the heat to the second heat sink, and the second heat sink is used to improve the heat dissipation efficiency.

[0048] The second radiator can have a variety of structural forms. For example, the second radiator includes a first sub-body 5 and a second sub-body 6 fixedly connected by a fourth screw 74. The first sub-body 5 is provided with a third mounting hole 51 for the third screw 73 to pass through and a third blind-hole threaded hole (not shown in the figure) that cooperates with the fourth screw 74. The first sub-body 5 and the second sub-body 6 are correspondingly provided with arc grooves for clamping and fixing the heat pipe (not shown in the figure). During assembly, the first sub-body 5 is abutted against the second surface of the first radiator 1, and the third screw 73 is screwed into the second threaded hole 15 on the first radiator 1 through the third mounting hole 51 on the first sub-body 5 to achieve a fixed connection between the first sub-body 5 and the first radiator 1. The heat pipe is placed in the arc groove of the first sub-body 5, and the arc groove of the second sub-body 6 faces the first sub-body 5 and abuts against the heat pipe. The fourth screw 74 is screwed into the third threaded hole on the first sub-body 5 through the fourth mounting hole 61 on the second sub-body 6 to achieve a fixed connection between the first sub-body 5 and the second sub-body 6 and clamp the heat pipe. The coolant flowing in the heat pipe takes away the heat, thereby achieving heat dissipation. Specifically, the heat pipe can be set as a copper pipe to improve the heat dissipation efficiency. The first split body 5 and the second split body 6 are also preferably made of materials with good thermal conductivity. The cross-sections of the arc grooves of the first split body 5 and the second split body 6 can be set to semicircular, respectively, so that they can be aligned to form a complete circle that fits the outer surface of the heat pipe all around, which is conducive to improving the heat dissipation efficiency.
