[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Such as Figure 1 And 2An efficient heat-conducting capacitor housing is shown, which includes a housing body 1 integrally formed by die-casting of anti-interference metal. A plurality of heat sinks 3 are installed at the bottom of the housing body 1. The housing body 1 is provided with a placement area 2 for placing capacitors. An opening 5 communicating with the placement area 2 is provided on one side of the housing body 1. The housing body 1 includes a mounting groove 13 surrounding the opening 5. After adopting the structure of the present utility model, since the capacitor housing is formed by die-casting of anti-interference metal, by installing the capacitor in the capacitor housing, the interference of electromagnetic waves on the capacitor can be effectively reduced. After adopting the structure of the present utility model, since the plurality of heat dissipation blades installed at the bottom of the capacitor housing have a large contact area with the air and a high heat conduction efficiency, the problem of performance degradation of the capacitor caused by excessive temperature is effectively improved after the capacitor is installed in the housing.

[0023] In this embodiment, in order to enable the capacitor to have a certain anti-interference property, the anti-interference metal is made of ADC12 material, copper or cast iron. Preferably, it is die-cast and formed by ADC12 die-casting aluminum alloy. Relatively speaking, the ADC12 material has better anti-electromagnetic interference ability and is cheap. Using ADC12 material to make the capacitor housing has great advantages both in terms of anti-electromagnetic interference and price.

[0024] Furthermore, in order to enable the capacitor housing to have better waterproofness and airtightness, the mounting groove 13 is processed and formed by a laser etching process. A sealing ring 14 is provided on the mounting groove 13, and the sealing ring 14 is a silica gel pad. After adopting such a structure, since the mounting groove 13 is processed and formed by a laser etching process, and with this processing method and then using a silica gel pad for sealing, the waterproofness and airtightness of the capacitor heat dissipation housing are better.

[0025] Furthermore, in order to effectively improve the use of the internal space of the capacitor housing, a plurality of partition plates 11 are installed in the housing body 1, and the partition plates 11 are used to separate the plurality of placement areas 2 in the housing body 1. This capacitor housing is divided into a total of five placement areas 2 and can accommodate up to ten capacitors.

[0026] Further, in order to stably install the capacitor inside the housing main body 1, a plurality of positioning blocks 21 are placed in the placement area 2, and the positioning blocks 21 are used to position the installation position of the capacitor. The positioning blocks 21 include positioning blocks A211 provided at the four corners of the placement area 2, and the positioning blocks 21 include two positioning blocks B212 oppositely provided on the inner wall of the housing main body 1. The positioning blocks 21 include positioning blocks C213 for dividing the placement area into two installation areas, and the positioning blocks C213 are provided at the center of the placement area 2. Preferably, a cylindrical capacitor is installed inside the housing. The positioning blocks A211 and the positioning blocks B212 are positioning blocks with arc-shaped protrusions. By cooperating with the positioning blocks, the capacitor can be supported and positioned. Moreover, the positioning blocks C213 are positioning blocks with arcs provided at the center inside the placement area 2, and the placement area 2 can be divided into two areas for installing two capacitors.

[0027] Further, in order to stably install the capacitor on the device, mounting holes 12 for fixing the housing main body 1 are installed at both ends of the partition plate 11. When the capacitor housing needs to be installed, the capacitor can be installed only by matching the screws with the mounting holes.
