Abstract
The utility model discloses a kind of aluminum hull of electrolytic capacitor, comprise at the bottom of shell and shell wall, it is characterized in that: described shell wall is made up of inner casing and shell, a heat radiation cavity is formed between shell and inner casing, be coated with insulating barrier at the inner surface of described inner casing, described inner casing offers through described insulating barrier with the louvre of described heat radiation cavity connects.Compared with prior art, the utility model capacitor is while preventing capacitor core short circuit, can the heat produced during capacitor core work in shell wall be delivered in heat radiation cavity by louvre, reduce the ambient temperature of capacitor core, and add absorption by the endothermic tube in cavity and utilize, effectively control the temperature of capacitor.
Description
Technical field
The aluminum hull of a kind of electrolytic capacitor that the utility model relates to, belongs to capacitor technology field in electricity.
Background technology
Electrolytic capacitor is made up of aluminum hull and capacitor core.Aluminum hull is the shell of electrolytic capacitor, has protection capacitor core, isolated capacitor core and extraneous effect.The aluminum hull of electrolytic capacitor of the prior art is stamped to form by aluminium, in order to prevent capacitor core from contacting with aluminum hull, aluminum hull can be made to make the faults such as capacitor core short circuit, one deck dielectric film is all coated with at aluminum hull surfaces externally and internally, and capacitor can generate heat under normal usage, the existence of insulating barrier, can cause dispelling the heat, the useful life of capacitor be reduced, even has the possibility of blast.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides a kind of thermal diffusivity good thus the aluminum hull of the electrolytic capacitor in raising electrolytic capacitor life-span.
A kind of aluminum hull of electrolytic capacitor, comprise at the bottom of shell and shell wall, it is characterized in that: described shell wall is made up of inner casing and shell, a heat radiation cavity is formed between shell and inner casing, be coated with insulating barrier at the inner surface of described inner casing, described inner casing offers through described insulating barrier with the louvre of described heat radiation cavity connects.
In described heat radiation cavity, be provided with endothermic tube, in endothermic tube, be provided with heat absorption phase-transition liquid.
Compared with prior art, the utility model capacitor is while preventing capacitor core short circuit, can the heat produced during capacitor core work in shell wall be delivered in heat radiation cavity by louvre, reduce the ambient temperature of capacitor core, and add absorption by the endothermic tube in cavity and utilize, effectively control the temperature of capacitor.
