[0035] In one embodiment of the utility model, as Figures 1-6As shown, a heat dissipation structure is provided, comprising: an upper shell 1 with an upper three-dimensional groove 2 on the surface, a lower shell 4 with a lower three-dimensional groove 5 on the surface, a closed space 7 formed by the connection and conduction of the upper opening 3 and the lower opening 6, an injection port 8, a heat dissipation medium and a sealing element. The upper shell 1, the surface of the upper shell 1 is provided with the upper three-dimensional groove 2, the surface of the upper three-dimensional groove 2 is provided with the upper opening 3, and the upper three-dimensional groove 2 is communicated with the outside through the upper opening 3; the lower shell 4, the surface of the lower shell 4 is provided with the lower three-dimensional groove 5, the surface of the lower three-dimensional groove 5 is provided with the lower opening 6, and the lower three-dimensional groove 5 is communicated with the outside through the lower opening 6; the upper shell 1 is arranged on the top of the lower shell 4, the upper three-dimensional groove 2 and the lower three-dimensional groove 5 are distributed along the two sides of the upper shell 1 and the lower shell 4 with the upper shell 1 and the lower shell 4 as the center, the upper opening 3 and the lower opening 6 are connected and conducted to form the closed space 7; the injection port 8 is arranged between the upper shell 1 and the lower shell 4 and is communicated with the closed space 7, the closed space 7 is communicated with the outside through the injection port 8; the heat dissipation medium is injected into the closed space 7 from the injection port 8; and the sealing element is arranged at the port of the injection port 8 and seals the heat dissipation medium in the closed space 7.

[0036] The heat dissipation structure provided by the utility model is provided with the upper shell 1 and the lower shell 4. The surface of the upper shell 1 is provided with the upper three-dimensional groove 2 with the upper opening 3, and the surface of the lower shell 4 is provided with the lower three-dimensional groove 5 with the lower opening 6. When the upper shell 1 and the lower shell 4 are assembled, the upper opening 3 and the lower opening 6 are connected and conducted to each other, thereby forming a closed space 7. The injection port 8 arranged between the upper shell 1 and the lower shell 4 realizes the conduction between the closed space 7 and the outside. In the production process, the heat dissipation medium is injected into the closed space 7 from the injection port 8, and after the injection of the heat dissipation medium is completed, the sealing element is assembled at the injection port 8. Through the above structure design, the utility model can maintain the stable form of the heat dissipation medium in the high-temperature environment, ensure that the performance is not affected, thereby guaranteeing the heat dissipation efficiency and reliability of the heat dissipation structure when the heat dissipation structure is used for equipment.

[0037] Preferably, the heat dissipation medium can adopt heat-conducting silicone grease, which can effectively transfer the heat generated by the heating component to other parts of the heat dissipation structure and then dissipate to the surrounding environment.

[0038] Preferably, the sealing element can be a welding point. After the heat dissipation medium is injected into the closed space 7 from the injection port 8, the injection port 8 is welded to form a sealing element after the injection of the heat dissipation medium is completed, which effectively prevents the leakage of the heat dissipation medium and ensures the sealing performance and integrity of the closed space 7.

[0039] Preferably, the upper shell 1 and the lower shell 4 are inwardly recessed between the injection port 8 and the recessed structure 9. By placing the injection port 8 in the recessed structure 9, it can effectively avoid external physical damage such as scratching or collision. This not only prolongs the service life of the injection port 8, but also ensures its long-term stability, thereby ensuring the reliability of the heat dissipation system.

[0040] Preferably, the upper shell 1 is arranged on top of the lower shell 4, and the upper and lower three-dimensional grooves 2 and 5 are arranged along the two sides of the upper and lower shells 1 and 4, with the upper and lower shells 1 and 4 as the center. Not only the back of the upper three-dimensional groove 2, but also the side of the upper three-dimensional groove 2 can dissipate heat from the heat dissipation components, thereby increasing the contact area of the heat dissipation medium with the outside environment and improving the heat dissipation efficiency.

[0041] Further, the recessed structure 9 makes the upper shell 1, the lower shell 4, the upper three-dimensional groove 2 and the lower three-dimensional groove 5 all concave. The concave boundary can guide the heat to diffuse from the heat generating part to the surrounding environment, ensuring that the heat can be more evenly and efficiently transmitted, reducing the accumulation of heat in local areas.

[0042] Specifically, the mouth of the injection port 8 is flush with the mouth of the recessed structure 9, reducing the risk of leakage due to misalignment or gaps. This ensures that after injecting the heat dissipation medium, even under high pressure or long-term use, it can maintain good sealing performance and prevent the heat dissipation medium from leaking.

[0043] Preferably, the injection port 8 has a gap 10 with the inner wall of the recessed structure 9. By reserving an appropriate gap 10, it is ensured that the injection port 8 will not physically interfere with the inner wall of the recessed structure 9 during its entire life cycle due to accidental collision or long-term vibration, thereby avoiding potential mechanical damage and wear and tear problems, prolonging the service life of the injection port 8 and its surrounding components.

[0044] Preferably, the upper shell 1 and the lower shell 4 are chamfered. The chamfering process reduces the presence of sharp edges, making it easier to align and assemble the shell, reducing the risk of scratches or damage during assembly. In addition, the chamfered edge also helps to guide the shell components to dock more smoothly, reducing the likelihood of misoperation.

[0045] Preferably, the back of the upper stereoscopic groove 2 extends along the upper shell 1, and the upper stereoscopic groove 2 and the upper shell 1 are chamfered. The back of the lower stereoscopic groove 5 extends along the lower shell 4, and the lower stereoscopic groove 5 and the lower shell 4 are chamfered. The chamfering can effectively disperse the stress concentration points, especially in the damaged areas such as the edges of the groove. By reducing the stress concentration phenomenon at the sharp corners, material fatigue and crack propagation can be prevented, thereby prolonging the service life of the product. Moreover, the chamfering helps to guide the heat to be more evenly distributed in the entire groove area, avoiding heat concentration in some local positions. This not only reduces the formation of hot spots, but also promotes the diffusion of heat to all directions, improving the overall heat dissipation effect.

[0046] Specifically, the upper stereoscopic groove 2 and the lower stereoscopic groove 5 are formed to have an extended total width that is adapted to the diameter of the injection port 8. The flush interface reduces the possibility of misalignment during the installation of the seal, making the sealing effect more reliable.

[0047] Preferably, the length of the injection port 8 is less than the length of the closed space 7, which can effectively prevent the local accumulation of the heat dissipation medium during the injection process due to the excessive length of the injection port 8, and helps the heat dissipation medium to be more evenly distributed in the entire closed space 7, thereby improving the heat dissipation efficiency.

[0048] Preferably, the upper shell 1 extends away from the upper stereoscopic groove 2 with the upper stereoscopic groove 2 as the center, and the lower shell 4 extends away from the lower stereoscopic groove 5 with the lower stereoscopic groove 5 as the center. By extending away from the stereoscopic groove, the welding edges of the upper shell 1 and the lower shell 4 are expanded, forming a wider and smoother joint surface, which is also beneficial to the subsequent welding operation. These extended parts form additional support structures after welding, which helps to resist external forces such as impact, vibration, etc., thereby prolonging the service life of the product.

[0049] The above is only the preferred embodiment of the present application, and is not intended to limit the present application in any form. Although the present application is disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment.
