Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a potted assembly type vehicle-mounted filter heat dissipation structure. Background Technology

[0002] A filter is an electronic device that processes signals. It is designed to remove unwanted parts of a signal and retain the desired signal components. It is widely used in signal processing, communication, audio processing and other fields.

[0003] During filter operation, effective heat dissipation of the copper busbars is necessary to ensure normal operation. Currently, there are two common heat dissipation methods: one is to directly adhere heat dissipation pads to the surface of the copper busbars and dissipate heat through the cooling medium; the other is to use air cooling to blow air onto the filter surface for heat dissipation. However, these heat dissipation methods have certain shortcomings. First, the heat dissipation pad method requires sufficient exposed space on the copper busbars; when space is limited, the heat dissipation effect is limited, especially when multiple copper busbars need to be cooled simultaneously, making this method difficult to use effectively and potentially posing an insulation risk. Second, while air cooling can provide heat dissipation over a large area, its heat dissipation is not concentrated and its efficiency is low, failing to meet the requirements of high-efficiency heat dissipation.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The following is combined with Figures 1 to 6 This invention describes the heat dissipation structure of a potted and assembled vehicle-mounted filter.

[0033] See Figures 1 to 3 As shown in the figure, the potting assembly type vehicle filter heat dissipation structure provided in this embodiment of the utility model includes: a housing 100, a copper busbar 200 and a heat-conducting component 300.

[0034] A receiving groove 110 is formed inside the housing 100, and the receiving groove 110 is filled with a heat-conducting medium 400; the copper busbar 200 includes an exposed portion 210, which is located inside the receiving groove 110 and in contact with the heat-conducting medium 400; the heat-conducting element 300 is connected to the housing 100, and at least a portion of the heat-conducting element 300 is in contact with the heat-conducting medium 400.

[0035] The potting assembly type vehicle filter heat dissipation structure provided by this utility model has a receiving groove 110 in the housing 100, and the exposed part 210 of the copper busbar 200 is placed in the receiving groove 110 and filled with a heat-conducting medium 400. The heat generated by the copper busbar 200 during operation can be transferred to the heat-conducting medium 400, and then dissipated to the outside through the heat-conducting component 300, thus completing the heat dissipation work of the copper busbar 200. It has high heat dissipation efficiency and is not limited by space, solving the problems of space limitation and low heat dissipation efficiency in the existing filter heat dissipation technology.

[0036] Specifically, the number of copper busbars 200 can be single or multiple, configured according to the actual needs of the potted assembly-type vehicle filter heat dissipation structure. Regardless of the number of copper busbars 200, the exposed part 210 is always located within the receiving groove 110 and in contact with the heat-conducting medium 400, ensuring that heat can be effectively transferred to the heat-conducting medium 400 and dissipated through the heat-conducting component 300, thereby achieving a highly efficient heat dissipation effect.

[0037] The thermally conductive medium 400 can be made of various materials known in the prior art, such as thermally conductive silicone, thermally conductive paste, or thermally conductive adhesive. These thermally conductive materials all possess excellent thermal conductivity, electrical insulation, and high-temperature stability, making them suitable for heat dissipation of the copper busbar 200.

[0038] Among them, thermally conductive silicone has excellent thermal conductivity, electrical insulation, and high-temperature stability, effectively conducting heat to ensure the heat dissipation requirements of the copper busbar 200. It also has good flexibility and fillability, adapting to irregularly shaped receiving grooves 110 and providing better thermal contact. Furthermore, thermally conductive silicone has high anti-aging and chemical stability, and will not easily lose its thermal conductivity during long-term use. Both thermally conductive paste and thermally conductive adhesive have excellent thermal conductivity, effectively filling the tiny gaps within the receiving grooves 110 to meet the heat dissipation requirements of the copper busbar 200. Simultaneously, both thermally conductive paste and thermally conductive adhesive have good electrical insulation, preventing short circuits and electrical faults. Moreover, thermally conductive paste can operate stably over a wide temperature range.

[0039] The heat-conducting component 300 can also be made of a variety of materials known in the prior art, such as aluminum heat-conducting component 300, copper heat-conducting component 300, graphite heat-conducting component 300, and composite material heat-conducting component 300.

[0040] Among them, the aluminum thermal conductive component 300 has good thermal conductivity, enabling effective heat exchange with the external environment and facilitating the heat dissipation function of the thermally conductive silicone and copper busbar 200. The aluminum thermal conductive component 300 has a low density, reducing the overall weight of the potted, assembled vehicle-mounted filter heat dissipation structure and meeting the requirements for lightweight equipment. Simultaneously, aluminum also possesses good corrosion resistance and oxidation resistance, ensuring stability during long-term use. The copper thermal conductive component 300, graphite thermal conductive component 300, and composite material thermal conductive component 300 all exhibit excellent thermal conductivity, efficiently transferring heat from the thermally conductive medium 400 to the external environment, achieving efficient heat dissipation for the copper busbar 200. Furthermore, the copper thermal conductive component 300, graphite thermal conductive component 300, and composite material thermal conductive component 300 all possess strong high-temperature resistance and good aging resistance, maintaining good thermal management performance during prolonged use.

[0041] Preferably, in this embodiment, the thermally conductive medium 400 is thermally conductive silicone, and the thermally conductive component 300 is aluminum thermally conductive component 300.

[0042] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the housing 100 has an opening 120 on one side, and the receiving groove 110 is disposed adjacent to the opening 120 on one side; the heat-conducting component 300 includes a main body 310 and a plurality of mounting parts 320, the mounting parts 320 are connected to the main body 310, the main body 310 is disposed at the opening 120 to seal the opening 120, and the mounting parts 320 are connected to the housing 100.

[0043] By providing an opening 120 on one side of the housing 100 and arranging one side of the receiving groove 110 adjacent to the opening 120, the main body 310 of the heat-conducting component 300 can be effectively positioned at the opening 120, and a tight fixation is achieved by connecting the mounting part 320 to the housing 100. The main body 310 of the heat-conducting component 300 is designed at the opening 120, which, while sealing the opening 120, effectively dissipates heat from the heat-conducting medium 400, ensuring efficient heat transfer and a tight seal on the receiving groove 110.

[0044] The mounting part 320 and the housing 100 can be fixedly connected or detachably connected, and there is no limitation on this.

[0045] See Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, according to some embodiments of the present invention, the housing 100 is provided with a plurality of limiting grooves 130 corresponding one-to-one with the mounting part 320 along the circumferential direction, and the mounting part 320 is limited and engaged with the corresponding limiting groove 130.

[0046] By providing multiple limiting grooves 130 along the circumferential direction of the housing 100, each corresponding to a mounting portion 320, and by positioning the mounting portion 320 in relation to the corresponding limiting groove 130, precise positioning and secure fixing of the heat-conducting component 300 can be achieved. This ensures that the heat-conducting component 300 will not move at the opening 120, preventing loosening or displacement of the heat-conducting component 300 due to temperature changes or external forces, thereby guaranteeing the stability of heat dissipation efficiency and the long-term reliability of the equipment. Furthermore, the limiting grooves 130 also improve the ease of assembly of the potted assembly-type vehicle-mounted filter heat dissipation structure, reducing assembly errors.

[0047] See Figure 6 As shown in the example, in this embodiment, the main body 310 has two mounting portions 320 on its first side and one mounting portion 320 on its second side. Correspondingly, the housing 100 has two limiting grooves 130 on its first side corresponding to the opening 120 and one limiting groove 130 on its second side corresponding to the opening 120. During assembly, each mounting portion 320 is aligned with its corresponding limiting groove 130 and installed.

[0048] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the mounting part 320 is detachably connected to the housing 100.

[0049] By configuring the mounting part 320 and the housing 100 to be detachably connected, the heat-conducting component 300 can be easily installed and removed.

[0050] The detachable connection between the mounting section 320 and the housing 100 can be achieved in various ways, such as using threaded connectors 500 for auxiliary connection, snap-fit, or plug-in connection. The appropriate method can be selected based on specific design requirements and usage scenarios. Threaded connectors 500 provide strong fixing force, ensuring stability when the heat sink is fixed; snap-fit ​​and plug-in methods simplify the assembly process, facilitating quick disassembly and installation of the heat sink.

[0051] See Figure 4 and Figure 5 As shown, according to some preferred embodiments of the present invention, the housing 100 is provided with a plurality of mounting seats 140 corresponding one-to-one with the mounting part 320 along the circumferential direction, and the end of the mounting part 320 is connected to the corresponding mounting seat 140 by a threaded connector 500.

[0052] By providing multiple mounting seats 140 that correspond one-to-one with the mounting part 320 along the circumferential direction of the housing 100, and connecting the end of the mounting part 320 to the corresponding mounting seat 140 through a threaded connector 500, the heat-conducting component 300 can be stably installed and precisely connected.

[0053] Specifically, the threaded connector 500 provides strong fixing force, ensuring a firm connection between the mounting part 320 and the housing 100, preventing the mounting part 320 from loosening or falling off due to vibration or external force. It also facilitates later disassembly and maintenance.

[0054] See Figures 4 to 6 As shown in the example, in this embodiment, the first side of the housing 100 is provided with two mounting seats 140 spaced apart, corresponding to two mounting portions 320 on the first side of the main body 310, and the second side of the housing 100 is provided with one mounting seat 140, corresponding to one mounting portion 320 on the second side of the main body 310. During assembly, each mounting portion 320 is aligned with its corresponding mounting seat 140, and then each mounting portion 320 is fixed to its corresponding mounting seat 140 by means of a threaded connector 500.

[0055] See Figure 1 As shown, according to some embodiments of the present invention, the outer surface of the main body 310 is flush with the end face of the opening 120.

[0056] By setting the outer surface of the main body 310 to be flush with the end face of the opening 120, the main body 310 can be made to fit with the inner wall of the opening 120 on all sides, improving the stability of the heat-conducting component 300 when it is fixed. At the same time, it can prevent the main body 310 from protruding from the end face of the opening 120, thus reducing the overall thickness of the potting assembly type vehicle filter heat dissipation structure.

[0057] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the potting assembly type vehicle filter heat dissipation structure further includes a heat dissipation pad 600, which is disposed on the outer wall of the heat-conducting component 300.

[0058] By setting up the heat dissipation pad 600, the heat of the heat-conducting component 300 can be quickly and effectively transferred to the external environment, thereby improving the heat dissipation performance of the heat-conducting component 300.

[0059] Specifically, the heat dissipation pad 600 typically uses high thermal conductivity materials, such as copper, aluminum, or special thermally conductive rubber, which can accelerate heat dissipation, reduce the temperature of the heat-conducting component 300, prevent the heat-conducting component 300 from overheating, improve the overall thermal management effect of the potted assembly type vehicle filter heat dissipation structure, and ensure that the copper busbar 200 is maintained within the optimal temperature range during operation.

[0060] See Figure 1 and Figure 5 As shown, according to some embodiments of the present invention, the potting assembly type vehicle filter heat dissipation structure includes a plurality of copper busbars 200, and the exposed portions 210 of the plurality of copper busbars 200 are spaced apart in the receiving groove 110 along a first direction; a plurality of partitions 150 are spaced apart in the receiving groove 110 along the first direction to divide the receiving groove 110 into a plurality of sub-receiving grooves 111 corresponding one-to-one with the exposed portions 210, and the exposed portions 210 are disposed in the corresponding sub-receiving grooves 111.

[0061] It should be noted that the aforementioned "first direction" specifically refers to Figure 5 The direction of the arrow shown can be considered as the width direction of the heat dissipation structure of the potted assembled vehicle filter.

[0062] By arranging the exposed portions 210 of multiple copper busbars 200 at intervals along a first direction within a receiving groove 110, and by arranging multiple partitions 150 at intervals along the first direction within the receiving groove 110, the receiving groove 110 is divided into multiple sub-receiving grooves 111 corresponding one-to-one with the exposed portions 210. This achieves efficient distribution and reasonable arrangement of the copper busbars 200. Under the premise of optimizing the spatial layout, it also allows the exposed portions 210 of each copper busbar 200 to contact the heat-conducting medium 400, achieving sufficient heat dissipation. This not only optimizes the space utilization rate but also ensures that each exposed portion 210 can be individually accommodated in its corresponding sub-receiving groove 111, preventing mutual interference between the copper busbars 200 and improving the heat dissipation effect and operational stability of the potted assembly type vehicle filter heat dissipation structure.

[0063] See Figure 1 , Figure 4 and Figure 5 As shown, as an example, in this embodiment, there are three copper busbars 200 and two partitions 150, which can divide the receiving groove 110 into three sub-receiving grooves 111 spaced apart along the first direction.

[0064] The assembly process of the potting assembly type vehicle-mounted filter heat dissipation structure provided by this utility model is described below. (See attached image) Figures 1 to 6 As shown.

[0065] When assembling the potting assembly type vehicle filter heat dissipation structure provided by this utility model, each copper busbar 200 is installed onto the housing 100 in sequence, and the exposed portions 210 of each copper busbar 200 are distributed in the corresponding sub-accommodating grooves 111; then, the accommodating grooves 111 are filled with a heat-conducting medium 400, so that the exposed portions 210 of each copper busbar 200 are in contact with the heat-conducting medium 400; then, the heat-conducting component 300 is placed at the opening 120, and each mounting portion 320 of the heat-conducting component 300 is aligned with the corresponding mounting seat 140 on the housing 100, and each mounting portion 320 is fastened to the corresponding mounting seat 140 using threaded connectors 500; finally, the heat dissipation pad 600 is pasted onto the outer surface of the heat-conducting component 300.

[0066] When the potted assembly type vehicle filter heat dissipation structure is working, the copper busbar 200 generates heat, which is transferred to the heat-conducting medium 400 through the exposed part 210, then to the heat sink, and finally to the heat dissipation pad 600, thus completing the heat dissipation of the copper busbar 200.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
