Technical Field

The disclosure relates to a heat dissipation structure including a heat pipe and multiple heat dissipation fins, particularly to a heat dissipation module and a manufacturing method thereof.

Related Art

With the continuous increase of operating speed of electronic components, the generated heat is increasing accordingly. To solve the problem of high heat, the industry has developed various types of heat dissipation devices for heat dissipation. However, related-art heat dissipation devices still have drawbacks in practice.

A related-art heat dissipation device primarily includes a heat pipe, a thermo-conductive block and multiple heat dissipation fins. The heat pipe passes through both the thermo-conductive block and the heat dissipation fins. The thermo-conductive block is attached on an electronic component such as a central processing unit (CPU), so that the heat generated from the electronic component is dissipated to the outside through the heat dissipation fins and heat pipe.

In the process of inserting the heat pipe into the heat dissipation fins, however, the efficiency of heat dissipation and structural strength of the heat dissipation device are adversely affected if the heat dissipation fins cannot be firmly positioned on the heat pipe. Thus, how to firmly position the heat dissipation fins on the heat pipe is an important issue to be solved for the industry.

In view of this, the inventors have devoted themselves to the above-mentioned related-art art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems. Finally, the disclosure which is reasonable and effective to overcome the above drawbacks is provided.

In an embodiment of the disclosure, the disclosure provides a heat dissipation module, which includes a heat pipe, multiple heat dissipation fins and multiple rings. The heat pipe has a peripheral wall. Each heat dissipation fin has a through hole and an annular wall disposed on an outer edge of the through hole.

Secondly, as shown in the step b) of FIG. 1 and FIGS. 2-4, a ring 3 is provided. The ring 3 is a conic ring 31. The conic ring 31 has an upper bottom opening 311 and a lower bottom opening 312. The upper bottom opening 311 and the lower bottom opening 312 are arranged on an upper side and a lower side of the conic ring 31 respectively. An inner diameter S2 of the upper bottom opening 311 is less than an outer diameter W2 of the annular wall 22, and an inner diameter S3 of the lower bottom opening 312 is greater than an outer diameter W2 of the annular wall 22. The conic ring 31 is adapted to sheathe the annular wall 22. In other words, the annular wall 22 is sheathed with the conic ring 31.

In detail, in the step b), an inner diameter of the conic ring 31 tapers from the lower bottom opening 312 to the upper bottom opening 311. The heat pipe 1 has a top 12. The upper bottom opening 311 is more adjacent to the top 12 than the lower opening 312.

The size difference between the inner diameter S2 of the upper bottom opening 311 and the outer diameter W2 of the annular wall 22 is between 0.05 mm and 0.1 mm. The size difference between the inner diameter S3 of the lower bottom opening 312 and the outer diameter W2 of the annular wall 22 is between 0.05 mm and 0.1 mm. In this embodiment, a number of the ring 3 is, but not limited to, multiple.

In addition, a hardness of the ring 3 is greater than a hardness of the annular wall 22. For example, the annular wall 22 is made of copper and the ring 3 is made of a material with the hardness higher than that of copper, such as aluminum, iron, or stainless steel, etc.

Thirdly, as shown in the step c) of FIG. 1 and FIGS. 3-6, a heat pipe 1 having a peripheral wall 11 is provided. The heat dissipation fin 2 is adapted to tightly sheathe the heat pipe 1 through the through hole 21. In other words, the heat pipe 1 is compressedly sheathed with the heat dissipation fin 2. In this embodiment, a number of the heat pipe 1 is, but not limited to, multiple.

Furthermore, in the step c), the heat dissipation fin 2 is adapted to sheathe the heat pipe 1 from the top 12. The annular wall 22 is a cylindrical annular wall 222. An inner diameter S1 of the cylindrical annular wall 222 is less than an outer diameter W1 of the heat pipe 1. The size difference between the inner diameter S1 of the cylindrical annular wall 222 and the outer diameter W1 of the heat pipe 1 is between 0.05 mm and 0.1 mm, so that the cylindrical annular wall 222 compressedly connects the peripheral wall 11. For example, when the outer diameter W1 of the heat pipe 1 is 8 mm, the inner diameter S1 of the cylindrical annular wall 222 is about 7.9 mm, but not limited to this.

Fourthly, as shown in the step d) of FIG. 1 and FIGS. 5-9, a pressing jig 100 is provided. The pressing jig 100 is used for downwardly pressing the conic ring 31 to deform the conic ring 31 to be adapted to compressedly sheathe the annular wall 22 until the annular wall 22 is pressed and deformed by the ring 3 to be embedded and connected compressedly to the peripheral wall 11.

In detail, in the step d), the ring 3 is adapted to sheathe the annular wall 22 in a compressive manner to make the peripheral wall 11 be pressed by the annular wall 22 to form a cylindrical annular groove 112.

An outer periphery of each heat dissipation fin 2 is upwardly extended with multiple inverted T-shape connecting sheets 23 meshed with each other. The outer periphery of each heat dissipation fin 2 is outwardly extended with multiple latches 24 inserted respectively between adjacent two of the inverted T-shape connecting sheets 23. This makes the heat dissipation fins 2 firmly stacked and connected together.

Please refer to FIGS. 4-9, which show the using status of the heat dissipation module 10 of the disclosure. When the heat dissipation fin 2 is adapted to tightly sheathe the heat pipe 1 through the through hole 21, the heat pipe 1 may slightly stretch the annular wall 22 to make the heat dissipation fin 2 be unable to be firmly positioned on the heat pipe 1. After the ring 3 is adapted to sheathe the annular wall 22 in a compressive manner, the annular wall 22 is pressed by the ring 3 to be embedded and connected compressedly to the peripheral wall 11. This makes the annular wall 22 be closely in thermal contact with the peripheral wall 11 for the heat of the heat pipe 1 to be rapidly transferred to the heat dissipation fin 2. The heat dissipation fin 2 may also be firmly positioned on the heat pipe 1. Thus, efficiency of heat dissipation and structural strength of the heat dissipation module 10 are improved.

In addition, when the annular wall 22 is pressed toward the heat pipe 1 by the ring 3, a part of the annular wall 22 is securely embedded into the peripheral wall 11 of the heat pipe 1 and the part of the annular wall 22 compressedly connects the peripheral wall 11 of the heat pipe 1.
