Description

Technical Field

[0001] The utility model relates to the technical field of capacitor heat dissipation, in particular to a combined heat dissipation type power compensation capacitor. Background Art

[0002] Power compensation capacitors are a type of capacitor used for reactive power compensation in power grids. They are designed to reduce reactive power loss in the power grid, improve power utilization, and offset reactive power loss caused by inductive loads by storing and releasing capacitance when needed, thereby improving the power factor and stability of the power system.

[0003] In the application of traditional power compensation capacitors, when the power compensation capacitor operates for a long time and the temperature continues to rise, the aging process of the dielectric inside the capacitor will be accelerated. The aging of the dielectric will not only cause the electrical performance of the capacitor to gradually decline, such as reduced capacity and increased loss, but may also cause physical changes in the internal structure, such as uneven expansion and contraction of the dielectric. These changes will further aggravate the temperature rise of the capacitor, forming a vicious circle. What is more serious is that when the temperature of the power compensation capacitor exceeds the tolerance limit of its material, it may cause catastrophic consequences. For example, the dielectric material may melt or even burn due to high temperature, causing the capacitor to catch fire or explode. In addition, high temperature will accelerate the generation and accumulation of gas inside the capacitor. When the internal pressure reaches a certain level, the capacitor shell may bulge or even rupture, further exacerbating the safety risk. Utility Model Content

The working principle of the entire combined heat dissipation type power compensation capacitor is an efficient heat transfer process from the capacitor body to the environment. The initial cooling of the cooling mechanism, the heat conduction of the heat conduction mechanism, the extensive heat dissipation of the heat dissipation mechanism and the forced air cooling of the exhaust mechanism ensure the stable operation and long life of the capacitor body.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example

[0025] Combined heat dissipation power compensation capacitor, please refer to Figure 1 and Figure 2 , including a capacitor body 1, a cooling mechanism 2 for cooling the capacitor body 1 is provided on the outside of the capacitor body 1, a heat dissipation mechanism 4 for dissipating heat from the cooling mechanism 2 is provided on the upper end of the cooling mechanism 2, a heat conduction mechanism 3 for heat conduction is provided on the outside of the cooling mechanism 2, and an exhaust mechanism 5 for driving air flow is provided on both sides of the heat dissipation mechanism 4. The capacitor body 1 will generate heat during operation. In order to maintain its stable operation and prevent overheating, the cooling mechanism 2 is designed and installed on the outside of the capacitor body 1. The cooling mechanism 2 quickly absorbs and disperses the heat generated by the capacitor body 1 through the heat dissipation silicone grease 6. After absorbing the heat of the capacitor body 1, the cooling mechanism 2 needs to further conduct the heat and dissipate it to the environment. At this time, the heat conduction mechanism 3 plays a role. The key role is that the heat conduction mechanism 3 is closely connected with the cooling mechanism 2. After the heat is conducted by the heat conduction mechanism 3, it reaches the heat dissipation mechanism 4. The heat dissipation mechanism 4 is the final link for heat to be dissipated into the environment. The exhaust mechanism 5 drives the fan blades 504 to rotate through the motor 503 to generate directional wind flow, thereby accelerating the flow of air around the heat dissipation mechanism 4, thereby taking away more heat, forming a low-temperature area, and promoting continuous heat dissipation. The working principle of the entire combined heat dissipation type power compensation capacitor is an efficient heat transfer process from the capacitor body 1 to the environment. Through the initial cooling of the cooling mechanism 2, the heat conduction of the heat conduction mechanism 3, the extensive heat dissipation of the heat dissipation mechanism 4 and the forced air cooling of the exhaust mechanism 5, the stable operation and long life of the capacitor body 1 are ensured.

[0026] like Figure 3As shown, the cooling mechanism 2 includes an inner thermal sleeve 201, which is sleeved on the outside of the capacitor body 1, and the inner thermal sleeve 201 and the capacitor body 1 are detachably connected. A bottom ring 202 is fixedly provided at the lower part of the outer side of the inner thermal sleeve 201. Heat dissipation silicone grease 6 is applied between the inner thermal sleeve 201 and the capacitor body 1. An outer thermal sleeve 203 is fixedly connected to the center of the upper end of the bottom ring 202 near the edge. A sea wave crystal 204 is provided between the inner thermal sleeve 201 and the outer thermal sleeve 203. A sealed heat-conducting cover 205 is fixedly connected to the top of the outer thermal sleeve 203. The cooling mechanism 2 is tightly sleeved on the outside of the capacitor body 1 through the inner thermal sleeve 201 and is detachably connected to ensure direct contact with the capacitor body 1 and efficient heat conduction. The heat dissipation silicone grease 6 is further filled The tiny gap between the inner thermal sleeve 201 and the capacitor body 1 is narrowed, thereby improving the heat transfer efficiency. When the capacitor body 1 generates heat due to operation, the heat is first quickly transferred to the inner thermal sleeve 201 through the heat dissipating silicone grease 6. The inner thermal sleeve 201 transfers the heat to the Haibo crystal 204 on its outside, which is a highly efficient phase change material that can absorb and store a large amount of heat within a specific temperature range to achieve initial cooling. Subsequently, the heat continues to be transferred outward through the outer thermal sleeve 203 and the sealed heat-conducting cover 205. The design of multi-level thermal conductive materials significantly improves the efficiency of heat transfer from the capacitor body 1 to the outside, effectively preventing the capacitor from overheating. The detachable design facilitates the replacement of the heat dissipating silicone grease 6 or adjustment of the internal structure when necessary, thereby improving the maintenance convenience and service life of the equipment.

[0027] like Figure 4As shown, the heat conduction mechanism 3 includes a main heat conducting sleeve 301 and a first heat conducting plate 302. The main heat conducting sleeve 301 is sleeved on the outside of the outer heat conducting sleeve 203, and the main heat conducting sleeve 301 and the outer heat conducting sleeve 203 are detachably connected. The first heat conducting plate 302 is arranged on the top of the sealed heat conducting cover 205, and the lower end of the first heat conducting plate 302 and the upper end of the sealed heat conducting cover 205 are fitted with each other. A first U-shaped heat pipe 303 is fixedly arranged inside the first heat conducting plate 302, and a plurality of slots 304 are arranged on both sides of the main heat conducting sleeve 301. The outer sides of the plurality of first U-shaped heat pipes 303 are respectively sleeved inside the plurality of slots 304, and the plurality of first U-shaped heat pipes 303 and the main heat conducting sleeve 301 are detachably connected. The heat conduction mechanism 3 is connected by The main heat sleeve 301 is tightly mounted on the outside of the outer heat-conducting sleeve 203, and the first U-shaped heat pipe 303 is used to further efficiently extract heat from the cooling mechanism 2 and transfer it upward through the first heat-conducting plate 302. When the heat in the cooling mechanism 2 is transferred to the outer heat-conducting sleeve 203, the working fluid in the first U-shaped heat pipe 303 begins to evaporate and absorb heat, and then releases heat in the condensation section and condenses and refluxes, forming a closed-loop heat transfer system. This design greatly improves the heat conduction speed and efficiency, and quickly guides heat to a higher-level heat dissipation mechanism 4. The application of the first U-shaped heat pipe 303 significantly enhances the directional conduction capability of heat, reduces thermal resistance, and ensures rapid heat dispersion. The detachable design facilitates heat pipe replacement and overall upgrade, thereby improving the flexibility and maintainability of the equipment.

[0028] like Figure 5 and Figure 6 As shown, the heat dissipation mechanism 4 includes a second heat conducting plate 401, which is arranged at the upper end of the first heat conducting plate 302, and the lower end of the second heat conducting plate 401 is in contact with the upper end of the first heat conducting plate 302. A plurality of second U-shaped heat pipes 402 are arranged and fixedly connected at the lower part of the second heat conducting plate 401. A plurality of heat dissipation fins 403 are arranged and fixedly sleeved on the outer sides of both ends of the plurality of second U-shaped heat pipes 402. A plurality of ventilation slots 404 are arranged and penetrated inside the plurality of heat dissipation fins 403. The heat dissipation mechanism 4 is directly connected to the top of the heat conducting mechanism 3 through the second heat conducting plate 401, and the heat dissipation mechanism 4 is directly connected to the top of the heat conducting mechanism 3 by using the second heat conducting plate 401. The two U-shaped heat pipes 402 and the heat dissipation fins 403 effectively dissipate heat into the air. The heat from the heat conduction mechanism 3 is transferred to the second U-shaped heat pipe 402 through the second heat conduction plate 401, and then widely distributed on the heat dissipation fins 403. The air convection is accelerated through the ventilation slots 404 to take away the heat. The design of the large-area heat dissipation fins 403 and the ventilation slots 404 greatly increases the heat dissipation area, and cooperates with air convection to achieve efficient heat dissipation. The optimized heat dissipation fin 403 layout and modular design save space while ensuring heat dissipation efficiency, thereby improving the compactness of the overall design.

[0029] like Figure 7As shown, the exhaust mechanism 5 includes a protection frame 501, which is arranged on one side of the multiple heat dissipation fins 403. Clamping wires 502 are fixedly connected at both ends of one side of the protection frame 501. Two clamping wires 502 are hung on both sides of the multiple heat dissipation fins 403. A motor 503 is fixedly connected to the inside of the protection frame 501. The output end of the motor 503 is fixedly connected to the fan blade 504. A fan blade protection net 505 is fixedly connected to one side of the protection frame 501. The exhaust mechanism 5 is fixedly installed on one side of the heat dissipation fin 403 through the protection frame 501, and the fan blade 504 is driven to rotate by the motor 503. Enhance the air flow in the heat dissipation area. When the motor 503 is started, the fan blades 504 rotate rapidly to form a directional wind flow, which accelerates the removal of heat from the heat dissipation fins 403 through the ventilation slots 404 of the heat dissipation fins 403, and at the same time removes the surrounding hot air to form a low-temperature area, further promoting the heat dissipation effect. The air flow is actively enhanced by exhausting air, which significantly improves the heat dissipation efficiency, especially under high load or high temperature environment. The optimized design of the motor 503 and the fan blades 504 ensures good heat dissipation effect while also reducing the noise level and improving the comfort of equipment use.

[0030] Working principle: The heat generated by the capacitor body 1 during operation is first quickly transferred to the inner thermal sleeve 201 through the tightly fitting heat dissipation silicone grease 6. The inner thermal sleeve 201, as the core part of the cooling mechanism 2, not only forms a detachable connection with the capacitor body 1, but also uses the high-efficiency phase change material of the sea wave crystal 204 to absorb and store a large amount of heat within a specific temperature range to achieve initial cooling. Subsequently, the heat continues to be transferred outward through the outer thermal sleeve 203 and the sealed thermal cover 205. The heat-conducting mechanism 3 is tightly sleeved on the outside of the outer thermal sleeve 203 through the main heat-conducting sleeve 301, and uses the efficient heat conduction characteristics of the first U-shaped heat pipe 303 to further extract the heat and transfer it upward to the first heat-conducting plate 302. In this process The working fluid in the first U-shaped heat pipe 303 evaporates and absorbs heat, releases heat in the condensation section and condenses and refluxes, forming a closed-loop heat transfer system, which significantly enhances the directional conduction capability of heat. Finally, the heat reaches the heat dissipation mechanism 4, is transferred to the second U-shaped heat pipe 402 through the second heat conduction plate 401, and is widely distributed on the heat dissipation fins 403. The ventilation slots 404 opened inside the heat dissipation fins 403 accelerate air convection, effectively improving the heat dissipation efficiency. At this time, the exhaust mechanism 5 is started, and the motor 503 drives the fan blades 504 to rotate, forming a directional wind flow, which accelerates the removal of heat on the heat dissipation fins 403 and the surrounding hot air through the ventilation slots 404 of the heat dissipation fins 403, forming a low-temperature area, which further promotes the heat dissipation effect.
