Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically a large-capacity sealed capacitor. Background Technology

[0002] A large-capacity capacitor is a type of capacitor. A capacitor consists of two conductors close to each other with a non-conductive insulating medium in between. When a voltage is applied between the two plates of a capacitor, the capacitor stores charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance is the farad, and in circuit diagrams, the capacitor element is usually represented by the letter C.

[0003] Because capacitors have a fully sealed structure, the modules inside the capacitor will generate a lot of heat when they are working under high load for a long time. If the heat accumulates inside the device for a long time, it will significantly shorten the service life of the device. Therefore, those skilled in the art have provided a high-capacity sealed capacitor to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a large-capacity sealed capacitor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A large-capacity sealed capacitor includes a large-capacity capacitor, a first capacitor heat dissipation assembly, and a second capacitor heat dissipation assembly. The outer surface of the large-capacity capacitor is equipped with two terminals. The first capacitor heat dissipation assembly includes two sets of first heat-conducting plates. The outer surface of each first heat-conducting plate is connected to the large-capacity capacitor. The outer surfaces of the two sets of first heat-conducting plates are jointly equipped with second heat-conducting plates arranged at equal intervals.

[0007] As a further embodiment of this utility model: the outer surfaces of the two sets of second heat-conducting plates are jointly equipped with a third heat-conducting plate arranged in a ring, and the outer surface of the large-capacity capacitor is equipped with two sets of heat sinks.

[0008] As a further improvement of this utility model: each of the first heat-conducting plates has a first heat dissipation fin arranged at equal intervals on its outer surface, and each of the second heat-conducting plates has a second heat dissipation fin arranged in a ring on its outer surface.

[0009] As a further improvement of this utility model: each of the third heat-conducting plates has third heat dissipation fins arranged at equal intervals installed on its outer surface, and the second capacitor heat dissipation assembly includes two sets of support columns and a heat dissipation fan.

[0010] As a further improvement of this utility model: the outer surface of each set of support columns is connected to a large-capacity capacitor, and a connecting column is installed on the outer surface of each support column.

[0011] As a further improvement of this utility model: each of the connecting columns has a fixing column installed on its outer surface, and a connecting pipe is installed on the outer surface of multiple fixing columns.

[0012] As a further improvement of this utility model: a protective pad is installed on the inner wall of the connecting pipe, the outer surface of the protective pad is in contact with the cooling fan, and a ring of mounting holes is opened on the outer surface of the connecting pipe, with a mounting screw threaded onto the inner wall of each mounting hole.

[0013] As a further embodiment of this utility model: each of the connecting columns is provided with a first reinforcing rod and a second reinforcing rod on its outer surface, the end of each first reinforcing rod away from the connecting column is connected to a support column, and the end of each second reinforcing rod away from the connecting column is connected to a fixing column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This large-capacity sealed capacitor, through the cooperation of a first heat-conducting plate, a second heat-conducting plate, a third heat-conducting plate, a first heat dissipation fin, a second heat dissipation fin, a third heat dissipation fin, and a heat sink, can absorb and transfer the heat generated during the operation of the large-capacity capacitor in multiple ways and automatically dissipate heat through external wind. The setting of the cooling fan, the first reinforcing rod, and the second reinforcing rod not only makes the heat dissipation effect of the large-capacity capacitor better, thereby greatly increasing the service life of the large-capacity capacitor, but also greatly increases the stability of the cooling fan. The setting of protective pads, mounting holes, and mounting screws not only protects the cooling fan, but also allows people to disassemble and assemble the cooling fan, thus facilitating people to repair or replace the cooling fan.

[0024] Please see Figures 1-5In this embodiment of the present invention, a large-capacity sealed capacitor includes a large-capacity capacitor 1, a first capacitor heat dissipation assembly 2, and a second capacitor heat dissipation assembly 3. Two terminals 4 are installed on the outer surface of the large-capacity capacitor 1. The first capacitor heat dissipation assembly 2 includes two sets of first heat-conducting plates 201. The outer surface of each first heat-conducting plate 201 is connected to the large-capacity capacitor 1. The outer surfaces of the two sets of first heat-conducting plates 201 are jointly equipped with second heat-conducting plates 202 arranged at equal intervals. This can improve the heat dissipation effect of the device on the large-capacity capacitor 1, thereby significantly increasing the service life of the large-capacity capacitor 1. This solves the problem mentioned in the background art that the capacitor has a fully sealed structural design, which causes the internal module of the capacitor to generate a lot of heat when it is working under high load for a long time. If the heat accumulates inside the device for a long time, it will lead to a significant reduction in the service life of the device.

[0025] The outer surfaces of the two sets of second heat-conducting plates 202 are jointly equipped with a third heat-conducting plate 203 arranged in a ring. The outer surface of the large-capacity capacitor 1 is equipped with two sets of heat sinks 207. The outer surface of each first heat-conducting plate 201 is equipped with first heat sinks 204 arranged at equal intervals. The outer surface of each second heat-conducting plate 202 is equipped with second heat sinks 205 arranged in a ring. The outer surface of each third heat-conducting plate 203 is equipped with third heat sinks 206 arranged at equal intervals. The second capacitor heat dissipation assembly 3 includes two sets of support columns 301 and a cooling fan 306, which enables the device to absorb and transfer the heat generated by the large-capacity capacitor 1 during operation in multiple ways, preventing the large-capacity capacitor 1 from overheating and being damaged.

[0026] The outer surface of each set of support columns 301 is connected to a large-capacity capacitor 1. A connecting column 302 is mounted on the outer surface of each support column 301. A fixing column 303 is mounted on the outer surface of each connecting column 302. A connecting pipe 304 is mounted on the outer surface of multiple fixing columns 303. A protective pad 305 is mounted on the inner wall of the connecting pipe 304. The outer surface of the protective pad 305 contacts the cooling fan 306. A ring of mounting holes 307 is formed on the outer surface of the connecting pipe 304. A mounting screw 308 is threaded onto the inner wall of each mounting hole 307. Each connecting column 301... The outer surface of 02 is equipped with a first reinforcing rod 309 and a second reinforcing rod 310. The end of each first reinforcing rod 309 away from the connecting column 302 is connected to the support column 301, and the end of each second reinforcing rod 310 away from the connecting column 302 is connected to the fixing column 303. The cooling fan 306 can blow air onto the first cooling fin 204, the second cooling fin 205, the third cooling fin 206, the heat sink 207, the first heat-conducting plate 201, the second heat-conducting plate 202, and the third heat-conducting plate 203, thereby improving the heat dissipation effect of the device on the large-capacity capacitor 1.

[0027] The working principle of this utility model is as follows: First, the large-capacity capacitor 1 can be connected to the electronic device using the terminal 4. The first heat-conducting plate 201 and the heat sink 207 can absorb the heat generated by the large-capacity capacitor 1 during operation. The second heat-conducting plate 202 can absorb the heat of the first heat-conducting plate 201, and the third heat-conducting plate 203 can absorb the heat of the second heat-conducting plate 202. The first heat dissipation fin 204, the second heat dissipation fin 205, and the third heat dissipation fin 206 can absorb the heat of the first heat-conducting plate 201, the second heat-conducting plate 202, and the third heat-conducting plate 203, respectively. The cooling fan 306 can blow air to dissipate heat from the first heat dissipation fin 204, the second heat dissipation fin 205, the third heat dissipation fin 206, the heat sink 207, the first heat-conducting plate 201, the second heat-conducting plate 202, and the third heat-conducting plate 203. When the cooling fan 306 malfunctions, the mounting screw 308 can be removed to replace or repair the cooling fan 306.
