Abstract
Description
Technical Field
[0001] The utility model relates to capacitor technology, in particular to a capacitor. Background Art
[0002] Capacitors, represented by the letter C, are usually referred to as their ability to hold charge. The simplest capacitor is composed of plates at both ends and an insulating dielectric in the middle. When powered on, the plates are charged and voltage is formed, but due to the insulating material in the middle, the entire capacitor is non-conductive. Capacitors are one of the electronic components used in large quantities in electronic equipment, and are widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, control, etc. Existing capacitors, such as filter capacitors, are mostly simple in shape and do not have an external heat dissipation structure, which leads to the capacitor's easy failure when working for a long time, and the long-term inability to dissipate heat greatly reduces the service life.
[0003] Currently, there are also capacitors with heat dissipation structures, but their structure adopts an integrated design. Capacitors of different models and sizes cannot be used interchangeably and need to be designed individually, resulting in a waste of resources and requiring separate production. Utility Model Content
[0004] In order to solve the defects of the above-mentioned prior art, the utility model proposes a capacitor.
[0005] The technical solution of the utility model is achieved in this way:

[0007] A capacitor body, a heat sink is arranged outside the capacitor body, the heat sink consists of a heat sink section and symmetrically arranged elastic arms, a movable opening is formed between the symmetrically arranged elastic arms, the heat sink section consists of a plurality of heat sink protrusions, a heat sink opening is formed between the heat sink protrusions, and a placement area for placing the capacitor body is formed between the heat sink section and the symmetrically arranged elastic arms.
[0008] In the capacitor of the utility model, the elastic arm is provided with a contact section extending toward the placement area, and the contact section is connected to the elastic arm via a bent section.
[0009] In the capacitor of the utility model, arc-shaped portions are provided at the upper and lower ends of the contact section.
[0010] In the capacitor of the utility model, a strip groove is provided on the elastic arm.

[0013] In the capacitor of the utility model, a notch is provided on the heat dissipation protrusion.
[0014] The implementation of the capacitor of the utility model has the following beneficial effects: the capacitor has a compact structure, adopts a design separated from the capacitor, can match columnar capacitor structures of different models and sizes, improves practicality, does not require special targeted design, and reduces the manufacturing process. At the same time, placing the heat sink outside the capacitor can effectively improve the heat dissipation performance of the capacitor and extend the service life of the capacitor.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] like Figures 1 to 3 As shown, the capacitor of the utility model comprises a capacitor body 1 and a heat sink 2. The heat sink 2 is located outside the capacitor body 1 and is used to absorb the heat emitted by the capacitor body 1. A gap is left between the heat sink 2 and the capacitor body 1 to facilitate air flow and drive the heat on the capacitor body 1.
[0020] The heat sink 2 is composed of a heat sink section 3 and symmetrically arranged elastic arms 4, and a movable opening 5 is formed between the symmetrically arranged elastic arms 4. The size of the movable opening 5 can be changed according to capacitors of different sizes, so as to facilitate clamping and fixing capacitor bodies 1 of different diameters.
[0021] The heat dissipation section 3 is composed of a plurality of heat dissipation protrusions 6, and heat dissipation openings 7 are formed between the heat dissipation protrusions 6. The heat on the heat sink 8 is dissipated from the heat dissipation openings 7. The heat dissipation protrusions 6 are composed of symmetrically arranged heat sinks 8, and the heat dissipation protrusions 6 are triangular. A heat dissipation area 9 is formed in the middle of the heat sink 8. The heat dissipation area 9 is connected to the placement area 10 so that the cold air from the outside can enter the heat dissipation area 9 and take away the heat on the capacitor body 1.
[0022] The heat dissipation protrusions 6 are connected to each other through arc segments 11, and the arc segments 11 are in contact with the outer wall of the capacitor body 1. The heat dissipation protrusions 6 are provided with notches 12, which can keep the outside air from entering the heat dissipation area 9 and speed up the air circulation.
[0023] A placement area 10 for placing the capacitor body 1 is formed between the heat dissipation section 3 and the symmetrically arranged elastic arms 4 , and the size of the placement area 10 can be changed according to the size of the capacitor body 1 placed therein.
[0024] A deformation region 13 is formed between the elastic arm 4 and the capacitor body 1, and the deformation region 13 is expanded by the elastic arm 4 pushed by the capacitor body 1. The elastic arm 4 is provided with a contact section 14 extending toward the placement region 10, and the contact section 14 is connected to the elastic arm 4 through a bent section 15. The elastic arm 4 is provided with a strip groove 16, and the strip groove 16 enables air to enter the deformation region 13.
[0025] The upper and lower ends of the contact section 14 are provided with arc-shaped portions 17 , which can be used to guide the capacitor body 1 to push the contact section 14 , so that the elastic arms 4 open and the capacitor body 1 is placed in the placement area 10 .
[0026] The heat sink 2 has a simple structure and adopts an integrated design. It can be externally cooled according to capacitor bodies 1 of different models and sizes, and can be installed later. It has a wide range of adaptability and high practicality, effectively improving the heat dissipation performance of the capacitor body 1 and extending the service life of the capacitor body 1.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
