Description

Technical Field

[0001] This utility model specifically relates to an electrically insulating heat-conducting component. Background Technology

[0002] In modern electronic devices, electronic components such as semiconductors and transistors have stringent requirements for operating temperature. To ensure their stable and efficient operation, they are typically expected to operate in an environment close to the ambient air temperature. However, during actual operation, these electronic components generate a significant amount of heat due to factors such as the flow of current. If this heat cannot be dissipated effectively and promptly, the temperature of the electronic components will continue to rise, far exceeding the normal operating temperature range. This overheating not only severely affects the performance of the electronic components, degrading their operating characteristics, but also significantly shortens their lifespan, reduces the reliability of equipment operation, and may even adversely affect the overall operation of related equipment, causing malfunctions or safety hazards. In some devices, thermally conductive electrical insulators are placed between electronic components and heat sinks to meet insulation requirements. However, traditional thermally conductive electrical insulators have poor thermal conductivity in practical use, making it difficult to meet the required heat dissipation needs of the equipment. Furthermore, existing thermally conductive electrical insulators have poor mechanical properties and poor compatibility with the equipment.

[0003] Therefore, it is necessary to invent an electrically insulating heat-conducting component to solve the above problems. Utility Model Content

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-5 The electrically insulating heat-conducting assembly shown includes an electrically insulating main sleeve 1 and an electrically insulating secondary sleeve 2 sleeved inside it, both of which have a heat-conducting structure 3 installed inside them.

[0031] Specifically, the electrical insulator secondary sleeve 2 is spirally connected to the inner wall of the electrical insulator main sleeve 1, and the top of the electrical insulator secondary sleeve 2 is also provided with a top cover assembly 4, which is rotated and fixed.

[0032] Specifically, the heat-conducting structure 3 includes a main heat pipe 31 and a secondary heat pipe 32 respectively disposed inside the main sleeve 1 and the secondary sleeve 2 of the electrical insulator, with their outer walls in contact with the inner walls of the main sleeve 1 and the secondary sleeve 2 of the electrical insulator.

[0033] Specifically, the top cover assembly 4 includes a top cover 41, which is installed on the top of the electrical insulator sub-sleeve 2, and the top of the top cover 41 is also provided with a heat sink 42.

[0034] Reference Figure 5 The top cover 41 is rotatably installed on the top of the electrical insulator sub-sleeve 2, that is, the inner wall thread of the top cover 41 matches the outer wall thread of the top of the electrical insulator sub-sleeve 2, and the bottom of the top cover 41 is provided with a mounting groove 43 for nesting the top of the electrical insulator sub-sleeve 2. The electrical insulator sub-sleeve 2 is provided with a heat conduction groove 21 inside, and the secondary heat conduction pipe 32 is installed in the heat conduction groove 21. The top of the top cover 41 is also provided with an annular through groove 44 for installing the heat dissipation plate 42.

[0035] Specifically, the heat sink 42 is shaped to match the annular groove 44, and the heat sink 42 is provided with a plurality of evenly spaced heat dissipation holes 45. The outer side of the heat sink 42 is also provided with a plurality of mounting buckles 46. The top of the top cover 41 is located outside the annular groove 44 and is also provided with a fixing groove 47 matching the plurality of mounting buckles 46. The heat sink 42 is placed inside the annular groove 44.

[0036] Specifically, the mounting buckle 46 has an L-shaped overall cross-section, and its front end is installed in the fixing groove 47.

[0037] Reference Figure 5 The main sleeve of the electrical insulator 1 is provided with a main heat conduction groove 11. A main heat conduction pipe 31 is installed in the main heat conduction groove 11. The outer wall of the main heat conduction pipe 31 contacts the inner wall of the main heat conduction groove 11. The top of the main sleeve of the electrical insulator 1 is provided with limiting plates 12 on both sides at the groove opening of the main heat conduction groove 11. The limiting plates 12 are placed on the top of the main heat conduction pipe 31.

[0038] Specifically, an annular heat dissipation groove 13 is provided between the two limiting plates 12, and the size of the annular heat dissipation groove 13 is smaller than the size of the main heat pipe 31.

[0039] Reference Figure 1 The thread on the outer wall of the electrical insulator secondary sleeve 2 matches the thread on the inner wall of the electrical insulator main sleeve 1.

[0040] In this embodiment, the secondary sleeve 2 of the electrical insulator is helically connected to the inner wall thread of the main sleeve 1 of the electrical insulator via its outer wall thread, thereby achieving a fixed assembly of the two. During assembly, it is necessary to ensure that the threads are tightly engaged to avoid loosening that could affect the overall stability.

[0041] In this embodiment, a main heat pipe 31 is installed in the main heat-conducting groove 11 inside the main electrical insulator sleeve 1, ensuring that the outer wall of the main heat pipe 31 is in close contact with the inner wall of the main heat-conducting groove 11 to improve heat conduction efficiency. Simultaneously, limiting plates 12 on both sides of the top of the main electrical insulator sleeve 1 at the opening of the main heat-conducting groove 11 are positioned on top of the main heat pipe 31 to limit its movement and prevent it from falling off. An annular heat dissipation groove 13 is provided between the two limiting plates 12, which neither affects the installation of the main heat pipe 31 nor hinders heat dissipation. A secondary heat pipe 32 is installed in the heat-conducting groove 21 inside the secondary electrical insulator sleeve 2, similarly ensuring that the outer wall of the secondary heat pipe 32 is in close contact with the inner wall of the heat-conducting groove 21.

[0042] In this embodiment, the top cover 41 is rotated and fixed to the top outer wall thread of the electrical insulator sleeve 2 via its inner wall thread, and the mounting groove 43 at the bottom of the top cover 41 is nested in the top of the electrical insulator sleeve 2, further enhancing the stability of the connection. Then, the heat sink 42 is placed in the annular through groove 44 at the top of the top cover 41. Since the shape of the heat sink 42 matches the annular through groove 44, precise placement is achieved. The front ends of multiple L-shaped mounting buckles 46 on the outer side of the heat sink 42 are installed in the fixing groove 47 located on the top of the top cover 41 outside the annular through groove 44, thereby firmly fixing the heat sink 42.

[0043] In this embodiment, the main heat pipe 31 and the secondary heat pipe 32 are in close contact with the inner walls of the main sleeve 1 and the secondary sleeve 2 of the electrical insulator, respectively, which can quickly conduct the heat generated inside the component away, ensuring that the temperature of the electrical insulator is within a reasonable range during operation and avoiding the impact of high temperature on insulation performance.

[0044] Specifically, the heat sink 42 is provided with multiple evenly spaced heat dissipation holes 45, which increases the heat dissipation area. Combined with the auxiliary function of the annular heat dissipation groove 13, the heat conducted by the heat conduction structure can be quickly dissipated to the external environment, thereby improving the overall heat dissipation efficiency.

[0045] Specifically, the components are mostly connected by threaded or snap-fit ​​connections, allowing for easy disassembly and replacement when a component is damaged, thus reducing maintenance costs and difficulty. For example, rotating the top cover 41 allows it to be removed from the electrical insulator sleeve 2, facilitating the inspection or replacement of the internal secondary heat pipe 32; the heat sink 42 can be easily replaced by removing the mounting clip 46 of the heat sink 42.

[0046] Specifically, the combination of threaded connection and nested structure, as well as the fixing effect of limiting plate and mounting buckle, makes the entire component structurally stable after assembly, able to withstand certain external impacts and vibrations, ensuring that components will not easily loosen or fall off during use, and ensuring the normal operation of the component.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
