Outer cover protection type insulated aluminum electrolytic capacitor module

Abstract

An aluminum electrolytic capacitor module design adopting an outer cover protection insulation mode comprises a discrete aluminum electrolytic capacitor, a metal heat conduction base body component with a radiator fin structure, an insulation shell, an internal pressure release mechanism composed of the metal heat conduction base body component and the insulation shell, an electric connection bus terminal board and a capacitor module fixing installation structure. A capacitor module is formed by tightly assembling the discrete aluminum electrolytic capacitor and the metal heat conduction base body component without insulation, the insulation shell wraps an assembly of the discrete aluminum electrolytic capacitor and the metal heat conduction base body component with a radiator fin structure for safe insulation, an air cavity and a release outlet are formed to form the module internal pressure release mechanism, and meanwhile air circulation holes are formed in the corresponding positions of radiator fins of the metal heat conduction base body component, so that external circulation and heat dissipation of air are achieved.
