Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat dissipation coating for electrolytic capacitor shells. Background technique [0002] In the rapid development of society, all kinds of electrical products are developing in the direction of miniaturization, light weight, compactness and high efficiency. Therefore, electronic products with high power have been developed rapidly, and the resulting large amount of heat has no space to dissipate. It will directly affect the working stability, operation safety and service life of electronic products. Conventional cooling methods can no longer meet the heat dissipation requirements of high-power electronic products, so it is necessary to improve the heat dissipation rate of electronic products. Currently, the most used is Apply heat dissipation paint. [0003] Heat dissipation coating is to enhance the heat dissipation performance of the object by improving the radiation effic...

Problems solved by technology

[0004] At present, the shell of electrolytic capacitors is generally covered with PET as the appearance condition. The general service life of PET materials is about 1 year. Solve or diffuse, the electrolytic capacitor will age ahead of time with the increase of temperature, and the change of temperature under long-term work will also cause the power supply of electronic components to be unstable, causing certain harm
