Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an electrolytic capacitor and a heat dissipation shell thereof. A bottom surface of the heat dissipation shell is recessed inwardly so as to form a protruded column. A capacitor core sleeves the protruded column through an inner hole so as to realize installation. On one hand, a side wall of the protruded column is directly contacted with the capacitor core; relative to air propagation, a speed of realizing heat conduction through the direct contact is fast; and the protruded column is inserted into a center of the capacitor core through the inner hole so that heat of an electrolytic capacitor center can be rapidly conducted; on the other hand, through the side wall of the protruded column, a contact area of the heat dissipation shell and the capacitor core can be increased and a heat dissipation surface area of an outer side of the heat dissipation shell can be increased too so that a heat dissipation speed is fast. Therefore, the above electrolytic capacitor and the heat dissipation shell can rapidly conduct and emit the heat from the centers so that the heat can not be accumulated at a center of a product and heat dissipation performance is good.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an electrolytic capacitor and a heat dissipation case thereof. Background technique [0002] During the working process of aluminum electrolytic capacitors, due to the existence of impedance and capacitive reactance, it will generate heat. If the temperature of the product is too high, it will burn out the internal components and reduce the maximum load ripple current, thereby affecting the service life of the capacitor. Therefore, electrolytic capacitors need to dissipate heat well during operation. [0003] At present, generally, a plurality of grooves or ribs are provided on the surface of the capacitor case to increase the surface area of ​​the case, thereby achieving the purpose of improving the heat dissipation effect of the capacitor. [0004] However, the temperature at the center of the capacitor is much higher than at its surface. Taking a product with a diameter ...
