Abstract

The invention provides a thin-film capacitor with a heat dissipation structure, which comprises a shell, a base and a core, and is characterized in that the core is wound on a core rod, the lower end of the integrated core and core rod is provided with a lining plate, and the integrated core and core rod and the lining plate are arranged in the shell together, the lower end of the shell is provided with the base, the upper end of the shell is provided with a fixing cover, the core is provided with a wire, a gap between the core and the shell is filled with fixing glue, the lining plate is fixedly provided with electrodes, one end of each electrode is connected with the core through a wire, and the electrodes penetrate through the base. The thin-film capacitor is provided with a specific heat dissipation structure on a base film so as to enable air or water vapor remained in the film to be discharged quickly, epoxy resin of the core is filled with a heat-conducting insulating material so as to enable the epoxy resin to form a heat conducting path therein, heat generated in the using process of the capacitor is promoted to be dissipated into the environment, and a circumstance that the capacitor declines in electrical performance or even is out of operation because of an overhigh temperature in the using process is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a film capacitor with a heat dissipation structure. Background technique [0002] During the use of film capacitors, due to the existence of electrode resistance and dielectric loss (ie equivalent series resistance), the capacitor will generate heat. A part of the heat generated by a general capacitor will be dissipated into the surrounding environment, and part of it will cause the internal heating of the capacitor. This causes a change in the electrical properties of the capacitor. Moreover, long-term heating will lead to the aging of the film medium, the life attenuation, and in severe cases, it will appear as thermal breakdown. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a thin film capacitor with a heat dissipation structure, which overcomes the deficiencies of t...
