Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic capacitor technology, and in particular to an aluminum electrolytic capacitor with a heat dissipation structure. Background Technology

[0002] Aluminum electrolytic capacitors, also known as capacitors, are energy storage components. Their structure can be divided into three types: fixed capacitors, semi-variable capacitors, and variable capacitors. They are characterized by large capacitance, but also by large leakage current, large error, and poor stability. They are commonly used for AC bypass and filtering, and also for signal coupling when requirements are not high. Aluminum electrolytic capacitors can be classified into four categories: leaded aluminum electrolytic capacitors; horn-shaped aluminum electrolytic capacitors; bolt-type aluminum electrolytic capacitors; and solid aluminum electrolytic capacitors.

[0003] However, many existing aluminum electrolytic capacitors do not have heat dissipation capabilities and cannot dissipate the heat generated inside the aluminum electrolytic capacitor to the outside in a timely manner. As a result, the heat generated by the aluminum electrolytic capacitor during long-term operation cannot be dissipated, which affects the service life of the aluminum electrolytic capacitor. Utility Model Content

[0004] The main purpose of this invention is to provide an aluminum electrolytic capacitor with a heat dissipation structure, which can effectively solve the problem of not being able to dissipate the heat generated inside the aluminum electrolytic capacitor to the outside in a timely manner.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An aluminum electrolytic capacitor with a heat dissipation structure includes a capacitor body. The upper and lower ends of the outer surface of the capacitor body are symmetrically and movably connected to a bearing component. A plurality of support mechanisms are fixedly connected in a ring array on the outer side of the two bearing components that are close to each other. A plurality of heat-conducting mechanisms are fixedly connected at intervals on the outer side of the plurality of support mechanisms that are close to each other. A heat dissipation mechanism is fixedly connected on the outer side of the plurality of heat-conducting mechanisms that are close to each other. A dustproof mechanism is fixedly connected to the outer side of the two bearing components.

[0007] Preferably, the bearing component includes a fixed disk, the upper middle part of the outer surface of the fixed disk having a plurality of conical through holes communicating with the outside, and the middle part of the side wall of the outer surface of the fixed disk having an annular groove communicating with the outside.

[0008] Preferably, the support mechanism includes a support plate, and connecting plates are symmetrically fixedly connected to the upper and lower ends of the outer surface of the support plate. Fastening screws are threadedly connected to the middle of the side of the outer surface of the two connecting plates that are close to each other.

[0009] Preferably, the heat-conducting mechanism includes an arc-shaped plate, the inner surface of which is fixedly connected to a heat-conducting plate, and the outer surface of the arc-shaped plate is fixedly connected to the outer surfaces of two corresponding support plates.

[0010] Preferably, the heat dissipation mechanism includes two connecting blocks. The outer surfaces of the two connecting blocks that are close to each other are fixedly connected to a rectangular through groove. The outer surfaces of the two connecting blocks that are far from each other are respectively fixedly connected to the outer surfaces of two corresponding arc-shaped plates.

[0011] Preferably, the dustproof mechanism includes two fixing rings, and a plurality of support rods are fixedly connected in a ring array at one end of the outer surfaces of the two fixing rings that are close to each other. Dustproof nets are installed and fixed on the side of the outer surfaces of the plurality of support rods that are close to each other, and the inner surfaces of the two fixing rings are respectively fixedly connected to the inner cavity of the corresponding annular groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model can support the capacitor body through the bearing component, support the bearing component through the support mechanism, and absorb the heat generated by the capacitor body during operation through the heat conduction mechanism, thus improving the practicality of the device. Under the action of the heat dissipation mechanism, the heat absorbed by the heat conduction mechanism can be dissipated to the outside in a timely manner. Furthermore, the dustproof mechanism can prevent external dust from adhering to the outer surface of the capacitor body, thus improving the practicality and versatility of the device.

[0014] 2. This utility model uses several heat-conducting plates that are attached to the outer surface of the capacitor body to absorb the heat generated during the operation of the capacitor body in a timely manner. At this time, several rectangular through slots installed on the outside of the corresponding heat-conducting plates allow outside air to enter the device, thereby facilitating the discharge of the heat absorbed by the heat-conducting plates to the outside, thus improving the practicality and versatility of the device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 As shown, an aluminum electrolytic capacitor with a heat dissipation structure includes a capacitor body 1. Supporting components 2 are symmetrically and movably connected to the upper and lower ends of the outer surface of the capacitor body 1, providing support for the capacitor body 1. Several supporting mechanisms 3 are fixedly connected in a ring array on the outer sides of the two supporting components 2, providing support for the supporting components 2. Several heat-conducting mechanisms 4 are fixedly and spaced apart on the outer sides of the supporting mechanisms 3, absorbing the heat emitted by the capacitor body 1 during operation. Heat dissipation mechanisms 5 are fixedly connected on the outer sides of the heat-conducting mechanisms 4, dissipating the heat absorbed by the heat-conducting mechanisms 4 to the outside in a timely manner. A dustproof mechanism 6 is fixedly connected to the outer sides of the two supporting components 2, preventing external dust from adhering to the outer surface of the capacitor body 1.

[0022] To achieve the purpose of supporting the capacitor body 1, see [reference needed]. Figure 2 The supporting component 2 includes a fixed disk 21. The upper middle part of the outer surface of the fixed disk 21 has several conical through holes 22 that communicate with the outside, which can facilitate the timely dissipation of heat generated at the upper and lower ends of the outer surface of the capacitor body 1 to the outside. The middle part of the side wall of the outer surface of the fixed disk 21 has an annular groove 23 that communicates with the outside, which can fix the corresponding fixing ring 61.

[0023] To achieve the purpose of supporting the load-bearing component 2, refer to... Figure 2 The support mechanism 3 includes a support plate 31. Connecting plates 32 are symmetrically fixedly connected to the upper and lower ends of the outer surface of the support plate 31. Fastening screws 33 are threadedly connected to the middle of the side of the outer surface of the two connecting plates 32 that are close to each other.

[0024] By connecting two fastening screws 33 through the corresponding connecting plates 32 to the two fixed discs 21, the fixed discs 21 can be stably supported by the support plate 31.

[0025] In order to absorb the heat emitted by the capacitor body 1 during operation, see [reference needed]. Figure 3 The heat conduction mechanism 4 includes an arc plate 41, and a heat conduction plate 42 is fixedly connected to the inner surface of the arc plate 41, which can absorb the heat generated by the capacitor body 1 after long-term use. The outer surface of the arc plate 41 is fixedly connected to the outer surface of the two corresponding support plates 31.

[0026] In order to promptly dissipate the heat absorbed by the several heat-conducting mechanisms 4 to the outside environment, refer to... Figure 3 The heat dissipation mechanism 5 includes two connecting blocks 51. The outer surfaces of the two connecting blocks 51 are close to each other and are fixedly connected to a rectangular through groove 52, which can facilitate the timely dissipation of heat generated on the outer surface of the capacitor body 1 to the outside. The outer surfaces of the two connecting blocks 51 are far apart from each other and are respectively fixedly connected to the outer surfaces of two corresponding arc plates 41.

[0027] To prevent external dust from adhering to the outer surface of the capacitor body 1, refer to... Figure 4 The dustproof mechanism 6 includes two fixing rings 61. Several support rods 62 are fixedly connected to the outer surfaces of the two fixing rings 61 in a ring array at their close ends. Dustproof nets 63 are installed and fixed on the outer surfaces of the support rods 62 at their close ends. This can prevent external dust from falling on the outer surface of the capacitor body 1, which would make the heat dissipation of the capacitor body 1 poor. The inner surfaces of the two fixing rings 61 are fixedly connected to the inner cavities of the corresponding annular grooves 23.

[0028] It should be noted that the specific installation method, circuit connection method and control method of the capacitor body 1 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0029] The working principle of this utility model is as follows: the dustproof nets 63 can effectively prevent external dust from settling on the outer surface of the capacitor body 1. At the same time, when the capacitor body 1 generates a lot of heat due to long-term operation, the heat generated by the surface of the capacitor body 1 can be absorbed in time by the heat-conducting plates 42. The heat absorbed by the heat-conducting plates 42 can be dissipated to the outside in time by the rectangular through slots 52. Meanwhile, the air flow on the outer surface of the capacitor body 1 can also be improved by the rectangular through slots 52, thereby improving the heat dissipation.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
