Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor heat dissipation technology, and in particular to a capacitor rapid heat dissipation device. Background Technology
[0002] Capacitors are among the most widely used electronic components in electronic devices, extensively applied in circuits for DC blocking and AC switching, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. A capacitor generally consists of a casing, core, encapsulation material, and leads connecting the core to the leads. Existing capacitor casings have a planar outer wall structure, resulting in poor heat dissipation. Electrolytic capacitors with aluminum casings generate heat during assembly or operation, leading to poor heat dissipation. Prolonged heat buildup accelerates aging and directly impacts the capacitor's lifespan. Capacitor breakdown causes temperature and internal pressure increases, potentially damaging or even causing an explosion. Current heat dissipation devices typically consist of a casing around the capacitor, using fins or similar structures for auxiliary cooling. However, with numerous capacitor models, designing appropriate heat dissipation devices for each size is challenging. This application addresses these shortcomings. Utility Model Content
[0003] The purpose of this invention is to provide a fast heat dissipation device for capacitors, which solves the above-mentioned problems.
[0004] To address the aforementioned problems, this utility model provides a capacitor rapid heat dissipation device, comprising a first housing and a second housing. Both the first housing and the second housing are provided with heat dissipation structures. Both the first housing and the second housing are made of deformable material. The diameter and length of the first housing are smaller than those of the second housing. The first housing is provided with a buckle structure for fixing one end of the second housing. The second housing is provided with a tightening strap. The first housing is provided with a fixing component for connecting the tightening strap. The tightening strap and the fixing component are in friction engagement.
[0005] According to one embodiment of the present invention, the fixing component includes a main body, a fastening hole is provided in the main body, and a fastening bolt is installed on the main body.

[0013] According to one embodiment of the present invention, the length of the second shell is 1.4-1.8 times the length of the first shell.
[0014] The beneficial effects of this utility model are that by fixing one end of the second shell to the first shell, and then using a tightening strap and fixing assembly to cover the outside of the capacitor, the capacitor is enclosed, thereby increasing the heat exchange area of the capacitor, improving the heat dissipation effect, and achieving an explosion-proof effect. The second shell and the first shell can be used with capacitors within a certain size range, improving the applicability and reducing construction and procurement costs. Furthermore, when the capacitor deforms, the tightening strap can be moved to adapt to the amount of deformation. By setting a displacement detection module, when the amount of movement reaches a set value, the displacement detection module issues an alarm signal to remind maintenance personnel to inspect or replace the capacitor.

[0021] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.
[0022] A capacitor rapid heat dissipation device, such as Figure 1 The capacitor includes a first housing 1 and a second housing 2, both of which are arc-shaped plates. Both housings are made of deformable material, preferably aluminum. Both housings have a heat dissipation structure 3, which includes heat dissipation fins, wavy protrusions, etc., to increase the heat exchange area of the capacitor and achieve heat dissipation. The diameter and length of the first housing 1 are smaller than those of the second housing 2. The first housing 1 has a snap-fit structure 11 for fixing one end of the second housing 2. The snap-fit structure 11 includes fasteners on the first housing 1. The second housing 2 has a connecting hole 22. Figure 1 , 3 The fastener can be made of plastic or metal. After passing through the connecting hole 22, one end of the fastener is fastened to the fastening point on the first housing 1. The second housing 2 is provided with a tightening strap 21, which is preferably made of plastic. The first housing 1 is provided with a fixing component 4 for connecting the tightening strap 21. In use... Figure 3 The first housing 1 is attached to one side of the capacitor, and the diameter of the first housing 1 is less than or equal to that of the capacitor. Then, the second housing 2 is attached to the other side of the capacitor, and one end of the second housing 2 is fixed to the first housing 1. Then, the second housing 2 is wrapped around the outside of the capacitor using the tightening strap 21 and the fixing component 4, thereby wrapping the capacitor, increasing the heat exchange area of the capacitor, and improving the heat dissipation effect. The height of the first housing and the second housing is equal to or greater than the height of the capacitor, achieving the effect of explosion protection. Furthermore, the tightening strap 21 and the fixing component 4 are in friction fit, so that the tightening strap can move when the capacitor is deformed to adapt to the amount of deformation.
[0023] like Figure 4 The fixing component 4 includes a main body 41, which has a fastening hole 43 and a fastening bolt 42 installed on the main body 41. After the strap passes through the fastening hole 43, the fastening bolt is tightened to clamp the strap.
[0024] like Figure 5 The surface of the tightening strap 21 is provided with an anti-slip structure, which has anti-slip textures or serrated anti-slip protrusions.
[0025] A detection plate 44 is movably installed in the fastening hole 43, such as Figure 4 The detection plate 44 is disposed in the fastening hole 43 on the side opposite to the fastening bolt 42. After the tightening band 21 is installed in the fastening hole 43, it contacts the detection plate 44. The main body 41 is provided with a displacement detection module 45. When the capacitor deforms and the tightening band slides, the tightening band drives the detection plate 44 to move together. The displacement detection module 45 detects the amount of movement of the plate 44. When the amount of movement reaches a set value, the displacement detection module 45 issues an alarm signal to remind maintenance personnel to inspect or replace the capacitor. The main body 41 is provided with a battery module that powers the displacement detection module 45, and it can also be connected to a circuit to provide power.
[0026] Preferably, the displacement detection module 45 is a Hall displacement sensor.
[0027] Preferred, such as Figure 2 At least two tie straps 21 are provided, and the number of corresponding fixing components 4 is the same as the number of tie straps 21.
[0028] To ensure a good covering effect, the length of the second shell 2 is 1.4-1.8 times the length of the first shell 1.
[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
