[0024] It should be explained that, in the case of no conflict, the embodiment in the utility model and the features in the embodiment can be combined with each other. The utility model will be explained in detail below by combining with the embodiment and referring to the drawings.
[0025] By referring to Figures 1 to 5As shown, this utility model provides a heat dissipation structure, which includes: a mounting box 10 having a mounting cavity 11, the top of the mounting box 10 having an opening communicating with the mounting cavity 11, the remaining parts of the mounting box 10 being sealing surfaces and sealed to each other, a mounting position being provided in the mounting cavity 11, the mounting position being configured to install a filter; and an insulating thermally conductive medium filling the mounting cavity 11 and immersing at least part of the filter.
[0026] In this embodiment, the top of the mounting box 10 has an opening communicating with the mounting cavity 11. The rest of the mounting box 10 is a sealed surface and is sealed to each other. That is, only the top of the mounting box 10 has an opening communicating with the outside, and the rest of the box does not have any openings or through holes communicating with the outside. The filter 20 is installed in the mounting position. At this time, the filter 20 is located in the mounting cavity 11, which is filled with an insulating and thermally conductive medium. The insulating and thermally conductive medium immerses at least part of the filter 20. The thermal conductivity of the insulating and thermally conductive medium is much higher than that of air. Therefore, compared with the prior art of placing the filter in the air for heat dissipation, the above arrangement can significantly improve the heat dissipation effect and efficiency.
[0027] In one embodiment, the filter is an EMI filter, i.e., an electromagnetic interference filter.
[0028] Radiated emission testing in EMI testing ranges from 30 to 1000 MHz. The higher the frequency, the greater the influence of distributed parameters. Even slight changes in the position of objects surrounding the filter can alter its distributed parameters, making it difficult to guarantee consistent EMI test results. To address this issue, in one embodiment of this invention, the filter is completely immersed in an insulating and thermally conductive medium.
[0029] In this embodiment, the insulating thermally conductive medium has a higher thermal conductivity than air. When it completely immerses the filter, it can significantly improve heat dissipation efficiency and ensure that all parts of the filter can dissipate heat evenly, avoiding performance degradation or damage caused by local overheating. In addition, since the filter 20 is completely immersed in the insulating thermally conductive medium, there is only the insulating thermally conductive medium between the filter 20 and the inner wall of the mounting box 10, with no other objects. On the one hand, it can ensure the consistency of distributed parameters, and on the other hand, it can reduce electromagnetic interference coupling and improve electromagnetic compatibility.
[0030] like Figure 5 As shown, in one embodiment, the top of the mounting box 10 is provided with a mounting opening, and a box cover 60 is provided at the mounting opening, with the opening being formed on the box cover 60.
[0031] In one embodiment of this utility model, the opening includes an inlet for insulating and heat-conducting medium and / or a wiring port 13.
[0032] like Figure 1 andFigure 5 As shown in the drawings, in one embodiment, the opening includes both the insulating heat-conductive medium filling port and the wiring port 13, i.e. the box cover 60 is provided with both the insulating heat-conductive medium filling port and the wiring port 13, and the insulating heat-conductive medium filling port and the wiring port 13 can be at the same position of the box cover 60 or at different positions of the box cover 60. When the insulating heat-conductive medium filling port and the wiring port 13 are at the same position of the box cover, the opening serves as both the insulating heat-conductive medium filling port and the wiring port 13, the input cable and the output cable can enter the installation cavity 11 through the opening, and the insulating heat-conductive medium can be filled into the installation cavity 11 through the opening after wiring.
[0033] In one embodiment, the opening includes the insulating heat-conductive medium filling port, i.e. the opening of the installation box 10 is the insulating heat-conductive medium filling port, and the box cover 60 is provided with only the insulating heat-conductive medium filling port, and the wiring port 13 is formed on the side wall or the bottom wall of the installation box 10.
[0034] In one embodiment, the opening includes the wiring port 13, i.e. the box cover 60 is provided with only the wiring port 13, and the insulating heat-conductive medium can be filled into the installation cavity before the box cover 60 is installed, and after the filling of the insulating heat-conductive medium is completed, the box cover 60 can be installed at the installation opening, and the input cable and the output cable can pass through the wiring port 13 of the box cover.
[0035] The insulating heat-conductive medium filling port is provided to allow the installation cavity 11 to be accurately filled with the insulating heat-conductive medium. Meanwhile, the design of the insulating heat-conductive medium filling port facilitates the replenishment of the insulating heat-conductive medium, facilitates maintenance, and ensures the heat dissipation effect. The wiring port 13 is provided for the electrical connection of the filter 20, such as the input cable and the output cable of the filter 20.
[0036] In one embodiment of the utility model, the insulating heat-conductive medium is heat-conductive silicone grease.
[0037] In the embodiment, the heat-conductive silicone grease has excellent heat conduction performance and can significantly improve the heat dissipation effect. In addition, the heat-conductive silicone grease has good fluidity, can effectively fill the small gaps and uneven surfaces between the filter 20 and the inner wall of the installation cavity 11, and improve the consistency and uniformity of heat conduction. Meanwhile, the heat-conductive silicone grease has insulating properties and can prevent electrical short circuit between the filter 20 and the surrounding metal structure, providing additional electrical safety protection.
[0038] In one embodiment of the utility model, the installation box 10 is made of metal aluminum except the top part.

[0044] In one embodiment of the utility model, the heat-conducting insulating layer completely covers the bottom of the mounting box 10.
[0045] In this embodiment, since the heat-conducting insulating layer can uniformly fill the gap between the bottom of the mounting box 10 and the heat dissipation substrate, it helps to reduce structural thermal stress and avoid deformation or damage caused by temperature difference, which can not only ensure reliable lapping, but also reduce the influence of the gap on the heat dissipation effect.
