Abstract
The utility model discloses an aluminum electrolytic capacitor with a built-in bimetal thermal bridge. The aluminum electrolytic capacitor comprises a shell, wherein a capacitor chip is arranged in the shell; the capacitor chip has a hollow structure; the bimetal thermal bridge is arranged in the hollow structure and is in contact with the shell; capacitor pins are connected with terminals by a lead; heat dissipation sheets are strip-type, one ends of the heat dissipation sheets are in contact with the shell, and the other ends of the heat dissipation sheets are also in contact with the shell after penetrating through the bottom of the hollow structure of the capacitor chip and winding around the inner wall of the shell; the heat dissipation sheets can also be U-shaped; the U-shaped heat dissipation sheets and the strip-type heat dissipation sheets are connected by two kinds of materials respectively, a high-temperature contact and a low-temperature contact are arranged, and voltage difference exists between the two contacts; the bimetal thermal bridge quickly conducts the heat of the capacitor chip center to the shell in the form of current and by using the high-speed thermal conductivity of the metal, so that chip temperature resulted from a ripple current is lowered, service life of the aluminum electrolytic capacitor is prolonged, and ripple current resistant capability 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 is short and anti-ripple ability is 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 the aluminium electrolytic capacitor of bimetallic heat bridge, comprises shell, and capacitor body is set in the shell, it is characterized in that: this capacitor body tool one hollow-core construction, a pair of metal heat bridge 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 bimetallic heat bridge 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 bimetallic heat bridge is a U-shaped bimetallic heat bridge, 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.
Described bimetallic heat bridge is bar shaped, and its two ends are that different metals connects into.
The U-shaped both sides of U-shaped bimetallic heat bridge are that different metals connects into.
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.
