Abstract
The utility model discloses an aluminium electrolytic capacitor with an inbuilt heat-radiating metallic thermal bridge, comprising a housing, and the housing is internally provided with a capacitor core. The capacitor core has a hollow structure, and a heat-radiating metallic sheet is arranged in the hollow structure and is contacted with the housing; the capacitor core is connected with a terminal through a lead wire; one end of the heat-radiating metallic sheet is contacted with the housing, and the other end of the heat-radiating metallic sheet passes through the bottom of the hollow structure of the capacitor core and encircles the inner wall of the housing and then is contacted with the top of the housing; and the heat-radiating metallic sheet is U-shaped and is arranged in the hollow structure of the capacitor core, and the tops of the U-shaped heat-radiating metallic sheet are contacted with the housing at two sides respectively. According to the aluminium electrolytic capacitor adopting the abovementioned scheme, the thermal resistance between the internal capacitor core and the housing is reduced, and the heat of the capacitor core is rapidly transmitted to the housing, and thus the temperature of the capacitor core caused by ripple currents, etc., is lowered, the life of the aluminium electrolytic capacitor is prolonged and the capability of ripple resistance is improved.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor and manufactures the field, in particular reduce thermal resistance between the inside fuse of aluminium electrolytic capacitor and the shell, the heat of deriving fast fuse arrives shell, thereby reduce the caused fuse temperature such as ripple current, can prolong the aluminium electrolytic capacitor of Capacitor Load Life and the anti-ripple ability of raising.
Background technology
Traditional large-scale bolt structure aluminium electrolytic capacitor only has one deck to play the glue (organic substance) of fixation between its inner fuse and the shell; The heat that can not fast fuse be produced because its conductive coefficient is low is taken away, and causes the core temperature high.Thereby the life-span that causes electric capacity, short and anti-ripple ability was low.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of so that between the inside fuse of aluminium electrolytic capacitor and the shell thermal resistance reduce, the heat of deriving fast fuse arrives shell, thereby reduces the caused fuse temperature such as ripple current.
To achieve these goals, the utility model is by the following technical solutions:
Inside arranges heat radiating metal heat bridge aluminium electrolytic capacitor, comprises shell, and capacitor body is set in the shell, it is characterized in that: this capacitor body tool one hollow-core construction, a heat dissipation metal plate are arranged on rear in the hollow structure and housing contacts; Capacitor body is connected with terminal through lead-in wire.
The shell upper cover plate is provided with between cover plate and the shell explosion-proof valve and terminal is set on sealing ring, the cover plate.
At least one deck sleeve pipe is set on the described shell.
Described heat dissipation metal plate one end and housing contacts, the other end are passed from the hollow-core construction of capacitor body bottom behind the rear pile warp outer casing inner wall and housing contacts.
Described heat dissipation metal plate is one U-shaped, and capacitor body tool one hollow-core construction arranges in the capacitor body hollow-core construction, U-shaped top respectively with the housing contacts of both sides.
Adopt the aluminium electrolytic capacitor of such scheme, reduce thermal resistance between internal capacitor fuse and the shell, the heat of deriving fast fuse arrives shell, thereby the caused fuse temperature such as reduction ripple current can prolong Capacitor Load Life and improve anti-ripple ability.
