Abstract
Description
Technical Field
[0001] The utility model relates to the field of capacitors, in particular to a high temperature resistant capacitor structure. Background Art
[0002] Capacitor, also known as capacitor, is a device that holds electric charge and is also the main component of electronic circuits. Capacitors are composed of two close conductors with a layer of non-conductive insulating medium in between. They can store electrical energy and have the characteristics of charging, discharging, passing AC and blocking DC. Capacitors are one of the electronic components used in large quantities in electronic equipment and are widely used in circuits for DC blocking, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control.
[0003] When current passes through the internal medium of the capacitor, due to the existence of the medium resistance, a certain amount of energy loss will occur. This part of the lost energy is mainly released in the form of heat energy, causing the capacitor to heat up. Long-term high-temperature operation will accelerate the aging of the internal insulating material of the capacitor, resulting in a shortened life of the capacitor.
[0004] Therefore, it is necessary to propose a high temperature resistant capacitor structure to solve the above problems. Utility Model Content

[0012] Technical effects and advantages of the utility model:
[0013] 1. The heat-conducting structure provided in the utility model is provided on the outside of the capacitor.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides Figure 1 - Figure 4 A high temperature resistant capacitor structure is shown, comprising a capacitor 1. The capacitor 1 is an electronic component having the ability to store charge and energy.
[0022] The outer wall of the capacitor 1 is slidably connected to a shell 2, and the bottom of the shell 2 is fixedly provided with multiple and equidistant protrusions 5 for fixing the shell 2 to other objects, which can be welded by soldering or glued, which is not limited in this article.
[0023] The housing 2 is provided with a heat-conducting structure 3 for conducting heat to the capacitor 1 , mainly for dissipating the heat generated by the capacitor 1 during operation.
[0024] The heat-conducting structure 3 includes a first heat-conducting sheet 301, which has multiple and equidistant sliding plates set on the inner wall of the shell 2, and a heat sink 302 is fixedly set on the inner wall of the shell 2. One end of the first heat-conducting sheet 301 is connected to the heat sink 302, and the inner wall of the shell 2 is fixedly set with multiple and equidistant moisture adsorption sheets 303. The moisture adsorption sheets 303 are tightly attached to the outer wall of the capacitor 1, and can efficiently adsorb moisture or cold air inside the shell 2 and outside the capacitor 1, and quickly transfer it to the heat sink 302. In this way, the moisture adsorption sheets 303 not only help to maintain a dry environment around the capacitor 1 to prevent performance degradation or damage caused by moisture, but also can significantly improve the heat dissipation efficiency of the heat sink 302 by increasing the contact area between the heat sink 302 and the wet and cold air.
[0025] The outer wall of the capacitor 1 is in sliding contact with the side of the first heat conducting sheet 301 away from the heat sink 302, the inner wall of the housing 2 is fixedly provided with a second heat conducting sheet 304, the second heat conducting sheet 304 is fixedly connected to the heat sink 302, and a avoidance groove is provided at the bottom of the second heat conducting sheet 304 for avoiding the pins of the capacitor 1, and the outer wall of the housing 2 is fixedly provided with a dustproof net 305, the dustproof net 305 is connected to the heat sink 302, and the dustproof net 305 can effectively block dust in the air to ensure a clean operating environment for the capacitor 1;
[0026] Working principle: When the capacitor 1 is placed in the shell 2, the heat generated on the outside during its operation will be quickly transferred to the heat sink 302 through the first heat conductive sheet 301. At the same time, the heat at the bottom of the capacitor 1 will also be effectively transferred to the heat sink 302 via the second heat conductive sheet 304. Subsequently, the heat will be quickly dissipated to the outside through the heat dissipation holes, ensuring that the operating temperature of the capacitor 1 is effectively controlled. When the outside wind contacts the dustproof net 305, it will pass through the dustproof net 305 and contact the heat sink 302, further enhancing the heat dissipation effect.
[0027] The inner wall of the housing 2 is provided with a fixing structure 4 for fixing the capacitor 1, mainly enabling the housing 2 to adapt to and accommodate capacitors 1 of various specifications, thereby improving its versatility and practicality.
[0028] The fixed structure 4 includes a sliding groove 401, which is opened with multiple sliding grooves 401 and is equidistant on the inner wall of the shell 2. A spring 402 is fixedly set on the inner wall of the sliding groove 401, a sliding block 403 is fixedly set at one end of the spring 402, and a fixing plate 404 is fixedly set on the side of the sliding block 403 away from the spring 402.
[0029] An anti-skid pad 405 is fixedly provided on one side of the fixing plate 404 close to the capacitor 1 , and the anti-skid pad 405 is in squeeze contact with the outer wall of the capacitor 1 , thereby increasing the contact area and friction between the sliding block 403 and the capacitor 1 , thereby ensuring that the capacitor 1 can be clamped more firmly.
[0030] Working principle: When the capacitor 1 is placed in the housing 2, one of the sliding blocks 403 is pressed to compress the spring 402, so that the sliding block 403 slides smoothly into the sliding groove 401. Then, the capacitor 1 is placed in the housing 2, and the pressing hand is released, and the spring 402 returns to its original shape, thereby pushing the sliding block 403 to slide out of the sliding groove 401 and closely contact the outer wall of the capacitor 1, thereby firmly fixing the capacitor 1.
[0031] If the capacitor 1 needs to be taken out from the housing 2 , one of the pressing blocks only needs to be pressed, and the sliding block 403 will be compressed into the sliding groove 401 again, thereby releasing the fixation of the capacitor 1 and the capacitor 1 can be taken out from the housing 2 .
