Abstract
The utility model relates to a high heat radiation capacitor, and belongs to the capacitor technology field. The high heat radiation capacitor includes a housing, a core, wiring terminals, and a grounding stud. The core is arranged in the housing. The grounding stud is arranged on the bottom end face of the housing. The wiring terminals are arranged on the top end face of the housing. The high heat radiation capacitor is characterized in that the bottom end face of the housing is provided with fins; the fins are arranged near the grounding stud; and the fins are arranged into a cross shape. The high heat radiation capacitor is simple in structure and is reasonable in design. Because the bottom end face of the housing is provided with the fins, the capacitor can contact with a metal panel via the fins, so the contact area of the capacitor to a heating member is reduced. The air can flow in the space created by the fins to play the heat radiation function, so the high heat radiation capacitor has the advantages of simple structure, excellent heat radiation effect, long service lifetime, and the low cost.
Description
Technical field
The utility model relates to a kind of electronic component, is specifically related to high heat dissipation electrical container.
Background technology
Electric capacity is called in the common letter of capacitor, as its name suggests, is ' container of dress electricity ', is a kind of device that holds electric charge.Electric capacity is one of a large amount of electronic components that use in electronic equipment, is widely used in handing over every straight-through in circuit, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.For effectively transmitting or changing electric energy, improve its power factor, usually to use capacitor.In the prior art, capacitor is to be made of shell, binding post fuse and grounding screw, and wherein, fuse is placed in shell, is take polypropylene film as dielectric, rolls as electrode with the coat of metal on dielectric to form.Binding post penetrates from the end face of shell the electrode that connects fuse.Shell generally adopts the materials such as plastics or metal to make, its smooth outer surface.This capacitor is when inductance type and ballast support the use, the outer casing bottom end face at its grounding screw place often is fixed on same metal plate with ballast, along with extend service time, the heat that ballast produces is in the course of the work sent a telegraph the also heating of outer casing bottom end face of container by the contact Heat Conduction, capacitor is easy to occur the heat ageing phenomenon under long-time high-temperature condition, thereby have a strong impact on the capacitor physical life, so the heat dissipation problem of capacitor also more and more causes people's attention.
The utility model content
Technical problem to be solved in the utility model is to provide the high heat dissipation electrical container of a kind of simple in structure, good heat dissipation effect, long service life.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of high heat dissipation electrical container, comprise shell, fuse, binding post and grounding screw, fuse is arranged on enclosure, grounding screw is arranged on the outer casing bottom end face, binding post is arranged on the cover top portion end face, it is characterized in that: described outer casing bottom end face is provided with fin, and described fin is arranged on by grounding screw, and described fin is cross setting.
Described fin is provided with four.
The shape of described fin is identical with size.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, owing to having set up fin on the shell bottom end face, capacitor is with fin contacting metal panel, reduced the contact area of capacitor and heat generating member, and can play thermolysis during the spatial flow of the height that supports from fin when air, therefore, the utlity model has simple in structure, good heat dissipation effect, long service life, the advantage such as with low cost.
