[0015] Beneficial effects According to various embodiments of the present invention, the insulating and heat dissipation structure, compared with the traditional multi-layer insulating shell, has an inner sleeve component provided on the outer wall of the capacitor assembly. The inner sleeve component has both an insulating function and can stably dissipate heat. The heat dissipation assembly mainly plays the role of contacting the inner sleeve component to achieve stable heat dissipation. The outer shell component wrapped around the outer wall of the heat dissipation assembly has the function of stably insulating and isolating all internal structures such as the heat dissipation assembly, thereby achieving a stable insulating effect on the capacitor assembly while dissipating heat.

[0027] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0028] Example: Please refer to Figures 1 to 9 : The present invention proposes a high insulation capacitor, comprising: a capacitor assembly 1; an inner sleeve component 2 is sleeved on the outer wall of the capacitor assembly 1, and a heat dissipation component 3 is provided at the outer end of the inner sleeve component 2.

[0029] Furthermore, according to an embodiment of the present invention, the capacitor assembly 1 includes: a capacitor block 101, with external wires extending outward from both sides of the capacitor block 101. The connecting wires of the capacitor block 101 are configured with an upper and lower position structure. The extended wires of the capacitor block 101 are configured with both sides and at the upper and lower ends, so that the two sets of connecting wires are at the maximum spacing distance, thereby allowing the capacitor block 101 to perform insulation from the root position. Sealing plates 102 are provided on both sides of the extended wire positions of the capacitor block 101. The sealing plates 102 are provided at the wire positions of the capacitor block 101, so that the sealing plates 102 have a stable sealing effect on the capacitor block 101.

[0030] Furthermore, according to an embodiment of the present invention, the inner sleeve component 2 includes: an inner sleeve 201, which has a cylindrical structure and is made of a thermally conductive insulating material. The inner sleeve 201 is sleeved and installed on the outer wall of the capacitor assembly 1. The inner sleeve 201, made of insulating material, can stably insulate the capacitor assembly 1 when sleeved on it, while also conducting heat to the capacitor assembly 1. Limiting blocks 202 are snapped onto both ends of the inner sleeve 201. The two ends of the inner sleeve 201 are configured to be longer than the capacitor assembly 1. The inner sleeve 201, when wrapping the capacitor assembly 1 at both ends, further wraps the conductors of the capacitor assembly 1, increasing the insulation effect of the capacitor assembly 1. The inner sleeve 201 is made of aluminum nitride ceramic material for heat conduction. Aluminum nitride ceramic has a thermal conductivity of 150 to 320 W / (m・K), a temperature resistance of over 1800℃, strong insulation, and good chemical stability, making it suitable for use in high-end high-temperature electronic equipment. Compared with ordinary aluminum heat dissipation structures, it has better insulation. Thermal grease is added between the capacitor assembly 1 and the inner sleeve 201 to improve contact and heat conduction.

[0031] Furthermore, according to an embodiment of the present invention, the heat dissipation assembly 3 includes: a heat dissipation top frame 301, both the heat dissipation top frame 301 and the heat dissipation base frame 302 are composed of sheet-like plates. By configuring both the heat dissipation base frame 302 and the heat dissipation top frame 301 as sheet-like structures, both the heat dissipation base frame 302 and the heat dissipation top frame 301 have stable heat dissipation functions, while simultaneously increasing the overall airflow effect of the heat dissipation assembly 3. The heat dissipation top frame 301 and the heat dissipation base frame 302 are interlocked, and a groove is provided at the interlocking position of the heat dissipation base frame 302 and the heat dissipation top frame 301. The inner end of the groove directly contacts the inner sleeve component 2. The inner sleeve component 2 is installed in the groove inside the heat dissipation component 3, so that the heat dissipation component 3 can make stable contact with the inner sleeve component 2. At the same time, a thermal grease pad is added between the groove inside the heat dissipation component 3 and the inner sleeve component 2 to achieve better mutual heat conduction, thereby achieving stable contact heat dissipation between the heat dissipation component 3 and the inner sleeve component 2. The heat dissipation component 3 is made of pure copper. Pure copper has a thermal conductivity of 385 to 401 W / (m・K) at room temperature. Its thermal conductivity is second only to silver among metal materials, which can quickly transfer heat, making it better suited for use in electronic devices.

[0032] The specific usage and function of this embodiment: In this invention, when in use, the two ends of the capacitor block 101 are fixed with the sealing plate 102 by the glue, which increases the stable sealing effect between the capacitor assembly 1 and the outside. At this time, the wires at both ends of the capacitor block 101 are outwardly extended. The outer wall of the capacitor block 101 is fitted with the inner sleeve 201. The limiting blocks 202 on the left and right sides of the inner sleeve 201 limit and fix it, so that the inner sleeve component 2 is in close contact with the capacitor assembly 1, which achieves heat dissipation of the capacitor assembly 1 and insulation. At this time, the capacitor assembly 1 will be placed directly in the heat dissipation base 302 through the inner sleeve component 2. The heat dissipation base 302 and the heat dissipation top frame 301 are both set as multiple sets of spacers welded together, so that the heat dissipation assembly 3 has a stable heat dissipation effect. The heat dissipation base 302 and the heat dissipation top frame 301 are interlocked, so that the heat dissipation assembly 3 has a stable wrapping effect on the capacitor assembly 1, allowing the sheet-like heat dissipation assembly 3 to better dissipate heat from the capacitor assembly 1. At the same time, the heat dissipation assembly 3 isolates the capacitor assembly 1, which has a certain insulation effect.

[0033] Example 2: The outer wall of the heat dissipation component 3 is covered by the outer shell component 4. The upper and lower ends of the outer shell component 4 are snapped with auxiliary components 8. The left and right ends of the outer shell component 4 are snapped with external components 5. The snapping position of the external components 5 is screwed with contact components 6. The installation position of the external components 5 is slidably installed on the outer shell component 4. The protective components 7 are also set at the outer end of the external components 5.

[0034] Furthermore, according to an embodiment of the present invention, the outer casing assembly 4 includes: a protective shell 401, which has a box-like structure and is wrapped around the outer wall of the heat dissipation assembly 3. The protective shell 401 wrapped around the outer wall of the heat dissipation assembly 3 serves to insulate the heat dissipation assembly 3 from the capacitor assembly 1. The protective shell 401 has snap-fit ​​grooves 402 at the front, back, top, and bottom positions. The snap-fit ​​grooves 402 enable the snap-fit ​​fixing of the auxiliary component 8. The left and right end faces of the protective shell 401 have external sliding grooves 403, which facilitate the sliding installation of the protective component 7. The upper and lower ends of the protective shell 401 are longer than the heat dissipation assembly 3. By making the protective shell 401 longer than the heat dissipation assembly 3, it helps to extend and wrap the heat dissipation assembly 3, thereby increasing the insulation effect on the internal structure of the outer casing assembly 4.

[0035] Furthermore, according to an embodiment of the present invention, the external component 5 includes: an external block 501, which is snapped onto the left and right outer walls of the housing assembly 4. A fixing block 502 is also installed on the external block 501. Firstly, the external block 501 is made of conductive metal. The fixing block 502 screwed onto the external block 501 has the function of fixing the swing position of the external block 501 by fixing the fixing block 502. A connector 503 is fixed at the end of the external block 501, and the connector 503 at the end of the external block 501 is used as an external wire. A through hole is provided at the root of the external block 501. The through hole provided on the external block 501 has the function of assisting in the installation of the contact component 6.

[0036] Furthermore, according to an embodiment of the present invention, the contact component 6 includes: a contact shaft 601, the contact shaft 601 having a shaft structure, a thread provided on the outer wall of the contact shaft 601, and an adjusting block 602 provided at the outer end of the contact shaft 601. The adjusting block 602 provided on the contact shaft 601 has the function of adjusting the contact shaft 601 by screwing it, so that the contact shaft 601 can be controlled by the adjusting block 602. The contact shaft 601 is screwed to the root position of the external component 5 through the threaded structure. By directly screwing the contact shaft 601 to the root of the external component 5 through the thread, The contact shaft 601 can rotate on the external component 5 to achieve telescopic movement; a slot is provided on the inner side of the contact shaft 601, and a contact piece 603 is installed in the slot of the contact shaft 601. The contact pieces 603 are arranged in three groups in a circumferential array structure. By placing the contact pieces 603 inside the slot of the contact shaft 601, the contact pieces 603 can contact the wires of the capacitor assembly 1 when the contact shaft 601 telescopic, so that the external component 5 can be connected to the wires of the capacitor assembly 1 through the contact component 6, thus completing the on / off control function between the external component 5 and the capacitor assembly 1.

[0037] Furthermore, according to an embodiment of the present invention, the protective component 7 includes: a sliding block 701, which is a frame structure. The sliding block 701 is slidably mounted on the outer slide groove 403. The sliding block 701 is configured to be slidably mounted on the outer slide groove 403 so that the sliding block 701 can perform sliding movement. A protective plate 702 is provided on the inner end face of the side plate of the sliding block 701. The sliding block 701 is slidably engaged at the position of the external component 5. The protective plate 702 of the sliding block 701 has the function of assembling the external component 5, thereby achieving the function of assisting in insulating and protecting the external component 5.

[0038] Furthermore, according to an embodiment of the present invention, the auxiliary component 8 includes: a heat dissipation frame 801, which is configured as two sets of upper and lower structures. The side frames of the heat dissipation frame 801 are provided with arc-shaped structures. By setting the side frames of the heat dissipation frame 801 as arc-shaped frame structures, the heat dissipation frame 801 has a certain elasticity, allowing the heat dissipation frame 801 to be stably snapped onto the outer shell component 4. Heat dissipation plates 802 are provided on the front and rear frames of the heat dissipation frame 801. Two sets of fans are installed on the heat dissipation plates 802. By installing two sets of fans on the heat dissipation plates 802, the heat dissipation frame 801 and the heat dissipation plates 802 can achieve heat dissipation of the heat dissipation component 3. The auxiliary component 8 is installed on the top of the outer casing 4 to provide auxiliary heat dissipation. Usually, the heat dissipation component 3 itself has a stable heat dissipation effect. However, electronic devices are used intermittently and the usage is uncertain. The simple heat dissipation component 3 cannot guarantee heat dissipation during peak periods. Therefore, the auxiliary component 8 is installed on the top of the outer casing 4. When the auxiliary component 8 is running, it guides the airflow of the heat dissipation component 3, which helps to increase the contact between the heat dissipation component 3 and the airflow and enhances the heat exchange efficiency. Compared with ordinary computers, when the case has no fans, even if the heat source load is not high, the graphics card temperature is always higher than 72 degrees. After adding 3 to 4 fans to form a front-to-back airflow channel, the internal temperature of the case drops to more than 50 degrees.

[0039] The specific usage and function of this embodiment: In this invention, the outer wall of the heat dissipation component 3 is wrapped with the outer shell component 4. The outer shell component 4 has the effect of increasing the isolation of the entire device, effectively realizing the insulation function of the outer shell component 4. The upper and lower ends of the outer shell component 4 are both snapped on with heat dissipation frames 801. Four sets of heat dissipation plates 802 are provided on the heat dissipation frames 801, so that the auxiliary component 8 can assist in the heat dissipation of the sheet-like heat dissipation component 3. When the entire device is installed, the outer connecting block 501 is first snapped on the left and right outer walls of the outer shell component 4. The outer connecting block 501 adopts a metal conductor structure. The swing angle of the outer connecting block 501 is fixed by the fixing block 502. The connector 503 at the end of the outer connecting block 501 realizes the external connection. The function of the wire is that the contact shaft 601 is screwed onto the root of the external block 501. The adjusting block 602 at the outer end of the contact shaft 601 facilitates the rotation and adjustment of the contact component 6. The internal groove of the contact shaft 601 is provided with a contact piece 603. When the contact shaft 601 is rotated, the contact component 6 moves inward, so that the contact piece 603 in the groove of the contact shaft 601 contacts the wire end of the capacitor assembly 1, realizing the effect of connecting the external component 5 to the capacitor assembly 1 through the contact component 6. Thus, the contact component 5 can only be connected when the contact component 6 is rotated to a specified position, which is convenient to use. At the same time, when disassembling or not in use, rotating the contact component 6 can realize the disconnection process between the external component 5 and the capacitor assembly 1, ensuring the insulation effect of the device.

[0040] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
