Description

Technical Field

[0001] This utility model belongs to the field of capacitors, and relates to a capacitor, and more particularly to a heat dissipation type capacitor. Background Technology

[0002] A capacitor is an electronic component whose basic function is to store electric charge. It consists of two conductors close to each other, with a non-conductive insulating dielectric layer in between. When a voltage is applied between the two plates of the capacitor, it stores electric charge.

[0003] During operation, capacitors easily generate a lot of heat and heat up. When the temperature reaches a certain level, the insulation layer in the capacitor will break down, causing the capacitor to fail. Therefore, heat dissipation is required. However, the heat dissipation efficiency of existing capacitors is not high, and they cannot dissipate heat completely. At the same time, as the airflow moves in the heat dissipation channel, the increase in airflow temperature will lead to a decrease in heat dissipation efficiency.

[0004] For example, the heat dissipation capacitor with application number 202121129280.8 includes a capacitor body, an air guide shell on the outside of the capacitor body, a ventilation cover on the upper side of the air guide shell, a threaded through groove on the inside of the air guide shell, an inner groove on the inside of the ventilation cover, and a crescent-shaped cooling groove on the outside of the inner groove.

[0005] The aforementioned patent uses threaded slots to cool the capacitor body. However, the threaded slots are relatively long and narrow, which cannot effectively cover the capacitor body. At the same time, the air inside the threaded slots has difficulty exchanging heat with the outside, causing the air temperature to rise and reducing the heat dissipation efficiency.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figures 1 to 4As shown, this utility model can be implemented through the following embodiments: A heat dissipation capacitor includes a capacitor body 1, a mounting shell 2 and a fixing cover 3. The capacitor body 1 is installed inside the mounting shell 2. The fixing cover 3 closes the mounting shell 2. A mounting groove 31 is opened inside the fixing cover 3. A fan 4 is installed in the mounting groove 31. The fan 4 is connected to a motor 41. An air outlet channel 312 and an air inlet channel 311 are opened on the mounting groove 31. A heat dissipation groove 21 is opened on the mounting shell 2. A dust cover 5 is installed over the heat dissipation groove 21.

[0022] A fan 4 is installed inside the fixed cover 3, so that the airflow stirred by the fan 4 enters the mounting shell 2 through the air inlet slot 311, the mounting slot 31, and the air outlet channel 312 to dissipate heat from the capacitor body 1. The opening of the heat dissipation slot 21 allows the air flowing into the heat dissipation shell to quickly move away from the capacitor body 1, which facilitates the subsequent entry of cold airflow to dissipate heat from the capacitor body 1. The installation of the dust cover 5 is used to prevent external dust from adhering to the surface of the capacitor body 1 and affecting the heat dissipation efficiency.

[0023] like Figure 1 and Figure 3 As shown, the air inlet slot 311 is annular, and a dust cover 6 is installed at the air inlet slot 311. The annular air inlet slot 311 is used to fit the fan 4 to facilitate the flow of air; the dust cover 6 is used to block external dust and impurities from entering, which would cause dust to accumulate inside the mounting shell 2 and affect the heat dissipation efficiency.

[0024] like Figure 2 and Figure 4 As shown, the dust cover 5 is provided with a retaining ring 51, and the mounting shell 2 is provided with a positioning part 22. The retaining ring 51 is used to fix the dust cover 5 to the mounting shell 2; the positioning part 22 is used to provide a fixed position for the retaining ring 51, thereby improving assembly efficiency.

[0025] like Figure 2 and Figure 4 As shown, the positioning part 22 is provided with a mounting hole 221, the fixing ring 51 is provided with a sliding groove 511, the sliding groove is provided with a second sliding groove 512, and the end of the second sliding groove 512 is provided with a mounting hole 512a. The mounting hole 221 and the mounting hole 512a are fixedly connected by a fixing rod 7. The sliding groove 511 is provided with a plurality of second sliding grooves 512, which facilitates the adjustment and installation of different capacitors as needed; the fixing rod 7 is used to pass through the mounting hole 221 and the mounting hole 512a, and fix the fixing cover 3, the dust cover 5 and the mounting shell 2 into one piece.

[0026] like Figures 1 to 3As shown, a bracket 23 is provided on the outside of the mounting shell 2, and a fixing rod 7 is mounted on the bracket 23. The end of the fixing rod 7 is provided with a thread 71, and a spring 8 is provided between the fixing rods 7. The bracket 23 is used to install and restrict the fixing rod 7, preventing the fixing rod 7 from detaching from the fixing cover 3, which would prevent the fixing cover 3 from being fixedly connected to the mounting shell 2. The thread 71 is provided to connect with the mounting hole 221 of the mounting shell 2, ensuring a stable connection between the fixing rod 7 and the mounting shell 2, thereby ensuring the stable installation between the mounting shell 2 and the fixing cover 3. The spring 8 is provided to quickly reset the fixing rod 7 after it leaves the mounting hole 221, improving disassembly efficiency.

[0027] like Figure 2 and Figure 4 As shown, a sealing part 52 is provided at the lower end of the dust cover 5, and a sealing ring is installed on the inner wall of the sealing part 52. A corresponding sealing groove 24 is provided on the mounting shell 2. The sealing ring is installed in the sealing part 52, and the sealing ring and the sealing groove 24 cooperate to seal the groove 24, so that the dust cover 5 is stably installed on the mounting shell 2, while improving the sealing performance between the dust cover 5 and the mounting shell 2, and preventing airflow between the mating surfaces of the mounting shell 2 and the dust cover 5.

[0028] like Figure 2 As shown, a sealing plug 9 is installed on mounting hole 2 512a. The sealing plug 9 will be installed in mounting hole 2 512a where the fixing rod 7 is not inserted to prevent external airflow from entering the interior of mounting shell 2 through mounting hole 2 512a, which would cause external dust and other impurities to enter the mounting shell 2 and accumulate, thus achieving the insulation effect and affecting heat dissipation.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
