Problems solved by technology

[0002] Capacitors are electronic components that are widely used. With the rapid development of electronic information technology, the replacement speed of digital electronic products is getting faster and faster, which drives the rapid development of the capacitor industry. When the existing capacitors are working, if the ambient temperature is too high If it is high, the heat generated by the capacitor itself cannot be dissipated through normal channels, which will reduce the insulation performance of the metallized polypropylene film, thereby reducing the withstand voltage capability, and finally cause breakdown damage due to overheating of the capacitor, which will affect the normal use of the capacitor life

Abstract

The invention relates to the technical field of capacitors, in particular to a heat-resistant capacitor which comprises a shell, a heat dissipation unit and a protection unit, the shell comprises dustproof plates arranged on the two sides, the heat dissipation unit comprises a heat dissipation piece for discharging heat in the shell and a cleaning piece for cleaning the surfaces of the dustproof plates, the heat dissipation piece is located in the shell, and the protection unit is located in the shell. The cleaning piece is located on one side of the dustproof plate, and the protection unit comprises a protection cover located on one side of the exterior of the shell. According to the invention, hot air absorbing heat in a through groove is discharged through rotation of fan blades, so that the interior of the shell is cooled, the temperature in the capacitor is rapidly discharged, and thus the usability of the capacitor is ensured, the fan blades drive a second rotating rod while discharging the hot air, so that the second rotating rod drives a fixed rod to rotate, and the heat dissipation efficiency of the capacitor is improved. And the fixed rod drives the scraper blade to clean the surface of the dustproof plate embedded in the inner wall of the air outlet, so that the heat dissipation effect is prevented from being reduced due to excessive dust accumulation, and the normal service life of the capacitor is ensured.
