[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0020] Please refer to Figure 1 The heat dissipation module 100 according to one embodiment of the utility model includes at least two module bodies 10 and a heat pipe assembly 20. The module bodies 10 are connected to each other through the heat pipe assembly 20. The heat pipe assembly 20 includes a plurality of heat pipes 21 arranged in parallel and an elastic support 22. Each end of the heat pipe 21 is connected to a module body 10. The heat pipe 21 includes a heat pipe body 23 and an elbow 24 connecting the heat pipe body 23. Please refer to [reference needed]. Figure 2 The elbow 24 includes a corrugated pipe 240 and a sound insulation layer 25, an aluminum foil layer 26, and a soft rubber wrapping layer 27 sequentially disposed on the outer layer of the corrugated pipe 240. Please refer to [reference needed]. Figure 3 The flexible support 22 includes a support body 28 and a telescopic frame 29 connected to the support body 28. The support body 28 abuts against the elbow 24 to fix the elbow 24. One end of the telescopic frame 29 abuts against other contact surfaces, such as the casing of electronic products, etc., depending on the application scenario.

[0021] In the aforementioned heat dissipation module, the bend 24 of the heat pipe 21 is made of corrugated pipe, and the outer layer is successively provided with a sound insulation layer, an aluminum foil layer and a soft rubber wrapping layer, so that the airflow can be reduced when it reaches the bend, reducing the noise generated by the impact; at the same time, the elastic bracket 22 can better support the heat pipe, reduce the impact of the heat pipe on the outside, thereby reducing the noise outside the heat pipe; thus, the overall noise of the heat dissipation module is greatly reduced.

[0022] Please refer to Figure 1 The module body 10 mentioned above includes a cooling fan 11 and cooling fins 12. The cooling fins 12 include an aluminum layer and a radiating coating (not shown) on the outer surface of the aluminum layer. Adding a radiating coating to the cooling fins 12 can accelerate its heat dissipation speed and improve its heat dissipation efficiency. The cooling fan 11 and the cooling fins 12 can be configured using existing structures.

[0023] Furthermore, the module body 10 also includes a sound-absorbing cover (not shown), which covers the periphery of the cooling fan 11. The sound-absorbing cover can reduce the noise generated by the cooling fan 11 during operation, thereby reducing the noise of the entire cooling module 100.

[0024] The way and structure of the heat pipe assembly 20 in the module body 10 can refer to the existing heat dissipation module setting method.

[0025] The elastic support 22 is made of soft rubber material. It can provide some support and also increase its cushioning effect. Of course, the elastic support 22 can also be made of hard rubber materials such as plastic parts. There is no restriction here, and the choice can be made according to the application scenario.

[0026] Please refer to Figure 1 The heat pipe assembly 20 further includes a mounting base 201 through which each heat pipe 21 passes. The mounting base 201 serves to fix the heat pipes. In this embodiment, the heat pipe body 23 passes through the mounting base 201.

[0027] Please continue to refer to this. Figure 1 Furthermore, a guide vane 241 is provided inside the elbow 24, and the guide vane 241 is connected to the inner wall of the elbow 24. The guide vane 241 is installed inside the elbow 24 and can guide the airflow reaching the elbow 24 to flow along the heat pipe 21, further reducing the impact on the inner wall of the elbow 24.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
