As an example, the housing 1 is any one of aluminum, aluminum alloy, steel, or carbon steel.

That is, the material of the housing 1 may be any one of aluminum, aluminum alloy, steel or carbon steel, and the present invention is not limited thereto.

It should be noted that the graphene nano heat dissipation coating or the super-heat conduction infrared radiation heat dissipation coating sprayed on the surface of the capacitor can greatly improve the heat radiation coefficient of the substrate and reach more than 0.9 (the theoretical value is close to 1), thereby greatly accelerating the heat exchange efficiency; in addition, the graphene nano heat dissipation coating or the super-heat-conduction infrared radiation heat dissipation coating can radiate heat on the surface of the base material in a wavelength form of 1-13.5 microns, so that the surface temperature of a device is reduced, the service life of the capacitor is prolonged, and the stability of the capacitor is improved.

And moreover, a temperature rise test confirms that the same design product is obtained, after the graphene nano heat dissipation coating or the super heat conduction infrared radiation heat dissipation coating is sprayed on the metal shell, the heat dissipation level of the capacitor is improved, and the temperature of a hot spot is reduced by 1-10 ℃.
