[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 to 3, An embodiment provided by the present utility model: A safety capacitor resistant to high temperature and high pressure, including a housing 2. The housing 2 of this capacitor is made of high-strength flame-retardant epoxy resin, which can not only effectively protect the internal components from the influence of the external environment, but also ensure the stable operation of the capacitor in high-temperature and high-pressure environments, improving the overall reliability and safety. A sealing rubber cover 1 is fixedly connected to the top of the housing 2. The design of the sealing rubber cover 1 can not only prevent impurities such as dust and moisture from entering the capacitor interior, but also slow down the heat transfer to a certain extent, protecting the internal components from overheating. At the same time, the presence of the sealing rubber cover 1 also enhances the overall sealing of the capacitor, further improving its service life in harsh environments. A gasket 3 is fixedly connected to the bottom of the housing 2. This gasket 3 plays a role in buffering and shock absorption, reducing the damage to the internal components of the capacitor caused by vibration or impact, and can also assist in heat dissipation to a certain extent, reducing the working temperature of the capacitor. In the middle of the bottom of the gasket 3, a lead 4 is fixedly connected. This is an important channel for the capacitor to connect with the external circuit. An outlet sleeve 5 is fixedly connected to the outer wall of the bottom of the lead 4. The outlet sleeve 5 can protect the lead from damage and ensure the smooth transmission of current. At the same time, the presence of the outlet sleeve 5 also increases the aesthetics and practicality of the capacitor. An outlet connecting piece 6 is fixedly connected to the outer wall of the upper part of the lead 4, which makes it more convenient for the capacitor to connect with the external circuit, improving the installation efficiency. At the same time, the presence of the outlet connecting piece 6 also increases the flexibility and expandability of the capacitor. An anode foil 7 is fixedly connected to the outer wall of the outlet connecting piece 6. This is one of the core parts of the capacitor. The anode foil 7 adopts a high-quality metal vapor deposition layer (zinc-aluminum composite thickened type), which has excellent electrical conductivity and corrosion resistance, and can ensure the stable performance of the capacitor during long-term use. An electrolytic paper 8 is in contact connection with the outside of the anode foil 7, which can maintain stable electrochemical performance in high-temperature and high-pressure environments, providing a strong guarantee for the normal operation of the capacitor. At the same time, the presence of the electrolytic paper 8 also increases the energy storage capacity and stability of the capacitor. The electrolytic paper 8 is fixedly connected to the outside of the outlet connecting piece 6, and a cathode foil 9 is fixedly connected to the outer wall of the outlet connecting piece 6. The cathode foil 9 is also made of high-quality metal material, and together with the anode foil 7, they form two electrodes of the capacitor, and the charge storage and release are realized through the electrolytic paper 8. A voltage-resistant component for increasing the voltage resistance of the capacitor is fixedly connected to the inner wall of the housing 2, and a heat dissipation component resistant to high temperature is fixedly connected to the inner wall of the voltage-resistant component. The heat dissipation component includes a plurality of heat sinks 10, which are made of aluminum alloy and can effectively dissipate the heat inside the capacitor, reducing the working temperature of the capacitor and improving its service life and stability. A lead 12 is fixedly connected to the bottom of the outlet connecting piece 6.

[0033] Refer to Figures 2 - 4, the voltage-resistant component includes an insulation-enhancing coating 11, which is made of a mixture of polyethylene and polypropylene. The presence of this material can effectively improve the insulation performance of the capacitor, preventing problems such as current leakage and short circuits. An outer fixing connection of the insulation-enhancing coating 11 is provided with a tightening hoop 13. This design can fix and stabilize the internal structure of the capacitor, ensuring the tight connection and collaborative work between components. The bottom of the sealing rubber cover 1 is fixedly connected to the top of the insulation-enhancing coating 11, and the bottom of the insulation-enhancing coating 11 is fixedly connected to the top of the gasket 3.

[0034] Referring to Figures 2 to 4 , the top of the anode foil 7 is fixedly connected to the bottom of the sealing rubber cover 1. This design not only ensures the tight connection between the anode foil 7 and the sealing rubber cover 1 but also enhances the overall sealing performance of the capacitor. The top of the cathode foil 9 is fixedly connected to the bottom of the sealing rubber cover 1. Similar to the anode foil 7, the tight connection between the cathode foil 9 and the sealing rubber cover 1 not only ensures the stable operation of the cathode foil 9 but also further improves the overall performance of the capacitor. Through this design, it can be ensured that the cathode foil 9 will not be affected by the external environment during long-term use, maintaining its good electrical conductivity and corrosion resistance. The top of the electrolytic paper 8 is fixedly connected to the bottom of the sealing rubber cover 1, and its performance directly affects the energy storage capacity and stability of the capacitor. Connecting the electrolytic paper 8 tightly to the sealing rubber cover 1 can not only ensure the normal operation of the electrolytic paper 8 in high-temperature and high-pressure environments but also prevent the electrolytic paper 8 from deteriorating or being damaged due to the influence of the external environment. The bottom of the electrolytic paper 8 is fixedly connected to the top of the gasket 3. The design of the gasket 3 can not only play a buffering and shock-absorbing role, reducing the damage caused to the electrolytic paper 8 by vibration or impact, but also assist in heat dissipation to a certain extent, reducing the working temperature of the electrolytic paper 8. The bottom of the anode foil 7 is fixedly connected to the top of the gasket 3. Similar to the top connection, the tight connection between the anode foil 7 and the gasket 3 can enhance the overall structural stability of the capacitor and improve its vibration resistance and shock resistance. The bottom of the cathode foil 9 is fixedly connected to the top of the gasket 3. Through the auxiliary effect of the gasket 3, the working environment and conditions of the cathode foil 9 can be further optimized, enabling it to maintain good performance in high-temperature and high-pressure environments. The outer wall of the tightening hoop 13 is fixedly connected to the inner wall of the outer shell 2.

[0035] Working principle: When the capacitor is connected to the power supply, positive charges move to the anode foil 7, while negative charges move to the cathode foil 9. These charges form an electric field in the electrolytic paper 8, thus achieving the storage of electrical energy. When the capacitor is disconnected from the power supply and connected to the load, the charges stored on the anode and cathode move through the electrolytic paper 8 to the load, realizing the release of electrical energy. The high-quality metal vapor deposition layer (zinc-aluminum composite thickened type) can provide better electrical conductivity and corrosion resistance, enabling the capacitor to maintain stable performance during long-term use. In high-temperature situations, multiple heat sinks 10 absorb the heat in the capacitor. These heat sinks 10 are made of aluminum alloy and can effectively dissipate the heat inside the capacitor, reducing the operating temperature of the capacitor, thus achieving the purpose of cooling. Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
