Description

Technical Field

[0001] This utility model relates to the field of capacitor structure technology, and in particular to a high-temperature resistant, long-life capacitor structure. Background Technology

[0002] Capacitance describes a device's ability to store electrical charge. It is defined as the ratio of a device's charge to its potential. As a physical quantity, it is primarily used in circuit analysis and design to help engineers calculate charge storage, electric field energy, and other parameters within circuits, playing a crucial role in theoretical research and calculations. With the continuous advancement of semiconductor integrated circuit manufacturing technology, there has been a process of device miniaturization and micro-miniaturization. Capacitor structures are essential components of integrated circuits, and there are various types of capacitor structures within integrated circuit chips.

[0003] However, in existing technologies, prolonged high temperatures can cause changes in the crystal structure of electrode materials, leading to a decrease in their mechanical and electrical properties. Some alloy electrodes may exhibit grain growth and phase transformation at high temperatures, which reduces the strength and toughness of the electrodes, making them prone to deformation or breakage, and thus affecting the normal operation of the capacitor. Therefore, a high-temperature resistant, long-life capacitor structure has been proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that grain growth and phase transformation occur at high temperatures, which reduces the strength and toughness of the electrodes, making them prone to deformation or breakage, and thus affecting the normal operation of the capacitor. Therefore, this invention proposes a high-temperature resistant, long-life capacitor structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature resistant, long-life capacitor structure, comprising a protective cylinder and a core, wherein the protective cylinder is provided with multiple sets of irregularly shaped heat dissipation blocks, and irregularly shaped heat dissipation fins are fixedly installed on the outer walls of the multiple sets of irregularly shaped heat dissipation blocks; a circular insulating resin is sleeved on the outer wall of the core; and the inner walls of the multiple sets of irregularly shaped heat dissipation blocks are fixed to the outer walls of the circular insulating resin.

[0006] Preferably, a first high-temperature insulating ring plate is fixedly installed at one end of the protective cylinder, and a second high-temperature insulating ring plate is fixedly installed at the other end of the protective cylinder.

[0007] Preferably, four sets of circular insulating pads are fixedly installed on the outer wall of the protective cylinder, and the inner walls of the multiple sets of irregular heat sinks are fixed to the outer walls of the four sets of circular insulating pads.

[0008] Preferably, one end of the second high-temperature insulating ring plate has multiple sets of elongated holes, and multiple sets of irregularly shaped heat dissipation blocks are respectively inserted into the multiple sets of elongated holes.

[0009] Preferably, a high-temperature insulating material layer is fixedly installed on the inner wall of the protective cylinder, and the outer walls of the multiple sets of irregularly shaped heat dissipation blocks are all fixed to the outer wall of the high-temperature insulating material layer.

[0010] Preferably, the core is disposed inside the protective cylinder, and the two ends of the core are respectively fixed to one end of the first high-temperature insulating ring plate and the second high-temperature insulating ring plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the combination of circular insulating resin, multiple sets of irregularly shaped heat dissipation blocks, and multiple sets of irregularly shaped heat dissipation fins allows heat to be quickly conducted from the heating element to the circular insulating resin. Furthermore, the multiple sets of irregularly shaped heat dissipation blocks, in close contact with the outer wall, allow heat to be rapidly transferred to them. Upon contact between the multiple sets of irregularly shaped heat dissipation blocks and the multiple sets of irregularly shaped heat dissipation fins, the heat from the blocks is quickly transferred to the fins. Since the fins are exposed outside the protective cylinder, their heat can be quickly dissipated, thereby improving heat dissipation efficiency, ensuring that the electrical equipment operates within its normal temperature range, preventing damage to the core, and not affecting the normal operation of the capacitor.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a high-temperature resistant, long-life capacitor structure, including a protective cylinder 1 and a core 7. The protective cylinder 1 is provided with multiple sets of irregularly shaped heat dissipation blocks 5. Irregularly shaped heat dissipation fins 4 are fixedly installed on the outer walls of the multiple sets of irregularly shaped heat dissipation blocks 5. A circular insulating resin 8 is sleeved on the outer wall of the core 7. The inner walls of the multiple sets of irregularly shaped heat dissipation blocks 5 are fixed to the outer walls of the circular insulating resin 8.

[0021] The specific settings and functions of this embodiment are described below. By attaching a circular insulating resin 8 to the outer wall of the core 7, the circular insulating resin 8 has excellent electrical insulation properties, which can effectively prevent current from flowing in unwanted paths and prevent leakage of electrical equipment and lines, thereby ensuring the personal safety of users and the normal operation of equipment. At the same time, it also has good thermal conductivity, which can quickly conduct heat from the heating element to the circular insulating resin 8. In conjunction with multiple sets of irregularly shaped heat dissipation blocks 5 in close contact with the outer wall, heat can be quickly transferred to the multiple sets of irregularly shaped heat dissipation blocks 5. When the multiple sets of irregularly shaped heat dissipation blocks 5 are in contact with the multiple sets of irregularly shaped heat dissipation fins 4, the heat on the multiple sets of irregularly shaped heat dissipation blocks 5 will be quickly transferred to the multiple sets of irregularly shaped heat dissipation fins 4. Since the multiple sets of irregularly shaped heat dissipation fins 4 are exposed outside the protective cylinder 1, the heat of the multiple sets of irregularly shaped heat dissipation fins 4 can be quickly dissipated, thereby improving the heat dissipation efficiency, ensuring that the electrical equipment works within the normal temperature range, preventing damage to the core 7, and not affecting the normal operation of the capacitor.

[0022] The four sets of circular insulating pads 6 can isolate the multiple sets of irregular heat sinks 4 from the protective cylinder 1, preventing the multiple sets of irregular heat sinks 4 from directly contacting the protective cylinder 1 and causing some heat to be transferred to the protective cylinder 1.

[0023] Example 2: Figure 1 , Figure 2 and Figure 3As shown, a first high-temperature insulating ring plate 2 is fixedly installed at one end of the protective cylinder 1, and a second high-temperature insulating ring plate 3 is fixedly installed at the other end of the protective cylinder 1. Four sets of circular insulating pads 6 are fixedly installed on the outer wall of the protective cylinder 1. The inner walls of multiple sets of irregularly shaped heat sinks 4 are all fixed to the outer walls of the four sets of circular insulating pads 6. Multiple sets of elongated holes 10 are opened through one end of the second high-temperature insulating ring plate 3. Multiple sets of irregularly shaped heat sink blocks 5 are respectively inserted into the multiple sets of elongated holes 10. A high-temperature insulating material layer 9 is fixedly installed on the inner wall of the protective cylinder 1. The outer walls of multiple sets of irregularly shaped heat sink blocks 5 are all fixed to the outer walls of the high-temperature insulating material layer 9. The core 7 is set inside the protective cylinder 1, and the two ends of the core 7 are respectively fixed to one end of the first high-temperature insulating ring plate 2 and the second high-temperature insulating ring plate 3.

[0024] The overall effect of this embodiment is that the high-temperature insulating material layer 9 can always maintain good insulation properties, effectively prevent short circuits between conductors at different potentials, avoid current leakage, thereby greatly improving the safety of electrical equipment and reducing the risk of electric shock and equipment damage caused by leakage.

[0025] By installing a No. 1 high-temperature insulating ring plate 2 and a No. 2 high-temperature insulating ring plate 3 at both ends of the protective cylinder 1, the core 7 inside the protective cylinder 1 can be protected and also have an insulating effect.

[0026] The usage and working principle of this device are as follows: First, when the capacitor generates heat, the heat on the outer surface of the core 7 is absorbed by the circular insulating resin 8 and transferred to the multiple sets of irregularly shaped heat dissipation blocks 5 on the outer wall, and then to the multiple sets of irregularly shaped heat dissipation fins 4. Since the multiple sets of irregularly shaped heat dissipation fins 4 are exposed outside the protective cylinder 1, the heat on the multiple sets of irregularly shaped heat dissipation fins 4 will be blown away and dissipated by the external wind, which can quickly dissipate heat from the capacitor. Finally, by installing four sets of circular insulating pads 6 on the outer wall of the protective cylinder 1, the multiple sets of irregularly shaped heat dissipation fins 4 can be separated from the protective cylinder 1, preventing the multiple sets of irregularly shaped heat dissipation fins 4 from directly contacting the protective cylinder 1, which would cause some heat to be transferred to the protective cylinder 1.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
