Description

Technical Field

[0001] This case relates to a heat dissipation fin assembly, and more particularly to a heat dissipation fin assembly having two types of heat dissipation fins. Background Technology

[0002] As electronic devices advance, the demands for their functionality and operating speed also increase, resulting in a corresponding increase in the heat generated by electronic components during operation. To prevent electronic components from malfunctioning or failing due to overheating, heat dissipation modules are installed on them to remove the heat generated and lower their temperature.

[0003] Currently, most heat dissipation modules contain at least one set of heat sink fins, which transfer heat from electronic components to the external environment. Generally, to increase the heat dissipation efficiency of the heat sink assembly, the number of heat sink fins is increased to increase the heat dissipation area. However, in a limited space, increasing the number of heat sink fins reduces the distance between adjacent fins, leading to insufficient ventilation. It also causes airflow to increase speed as it passes between the fins due to the reduced spacing, reducing heat dissipation efficiency and increasing noise. Furthermore, reducing the thickness of all heat sink fins to increase their number reduces their strength, making them more susceptible to bending under external forces, resulting in reduced heat dissipation efficiency and damage to the product's appearance. Utility Model Content

[0004] This invention provides a heat dissipation fin assembly that can increase heat dissipation efficiency.

[0005] A heat dissipation fin assembly of this invention includes a housing, a plurality of first heat dissipation fins, a plurality of second heat dissipation fins, and a heat dissipation element. The housing has an accommodating space and an opening. Each first heat dissipation fin has a first side and a first thickness, and the plurality of first heat dissipation fins are disposed in the accommodating space, with the first side exposed to the opening. Each second heat dissipation fin has a second side and a second thickness, and the plurality of second heat dissipation fins are disposed in the accommodating space, wherein the plurality of first heat dissipation fins and the plurality of second heat dissipation fins are arranged alternately. The heat dissipation element is disposed in the accommodating space and connects the plurality of first heat dissipation fins and the plurality of second heat dissipation fins, wherein the first thickness is greater than the second thickness, and the first side is higher than the second side.

[0006] According to one embodiment of the present invention, the first thickness is 0.3 mm.

[0007] According to one embodiment of the present invention, the second thickness is 0.2 mm.

[0008] According to one embodiment of the present invention, the heat dissipation element further includes at least one heat pipe that passes through the plurality of first heat dissipation fins and the plurality of second heat dissipation fins.

[0011] According to one embodiment of the present invention, the plurality of first heat dissipation fins and the plurality of second heat dissipation fins are made of different materials.

[0012] According to one embodiment of the present invention, at least one of the plurality of second heat dissipation fins is disposed between adjacent plurality of first heat dissipation fins.

[0036] Please refer to Figure 1A and Figure 1B The heat dissipation fin assembly 100 of this invention includes a housing 110, a plurality of first heat dissipation fins 120, a plurality of second heat dissipation fins 130, and a heat dissipation element 140. The housing 110 has an accommodating space A and an opening 110a. Each first heat dissipation fin 120 has a first side 121 and a first thickness D1, wherein the plurality of first heat dissipation fins 120 are disposed in the accommodating space A, and the first side 121 is exposed in the opening 110a. Each second heat dissipation fin 130 has a second side 131 and a second thickness D2, wherein the plurality of second heat dissipation fins 130 are disposed in the accommodating space A, and the plurality of first heat dissipation fins 120 and the plurality of second heat dissipation fins 130 are arranged alternately. The heat dissipation element 140 is disposed in the accommodating space A and connects the plurality of first heat dissipation fins 120 and the plurality of second heat dissipation fins 130, wherein the first thickness D1 is greater than the second thickness D2, and the first side 121 is higher than the second side 131.

[0037] In detail, the opening 110a is provided in the first direction P. Since the first thickness D1 is greater than the second thickness D2, the area of ​​each first heat dissipation fin 120 projected onto the housing 110 in the first direction P is greater than the area of ​​each second heat dissipation fin 130 projected onto the housing 110 in the first direction P. Furthermore, since the first side 121 is higher than the second side 131, the length of each first heat dissipation fin 120 in the first direction P is greater than the length of each second heat dissipation fin 130 in the first direction P. That is, the surface area of ​​each of these first heat dissipation fins 120 is greater than the surface area of ​​each of these second heat dissipation fins 130. When the heat dissipation fin assembly 100 is subjected to an external force, since the first side 121 of each of the first heat dissipation fins 120 within the opening 110a is closer to the opening 110a than the second side 131 of each of the second heat dissipation fins 130, the first side 121 of each of the thicker first heat dissipation fins 120 will be affected by the external force first, so that the second side 131 of each of the thinner second heat dissipation fins 130 will not be affected by the external force, thereby protecting the second heat dissipation fins 130.

[0038] As described above, the second heat dissipation fins 130 are dispersedly disposed among the first heat dissipation fins 120. That is, in this embodiment, one of the second heat dissipation fins 130 is disposed between adjacent first heat dissipation fins 120. In another embodiment, two or more of the second heat dissipation fins 130 may also be disposed between adjacent first heat dissipation fins 120. Alternatively, one or more of the second heat dissipation fins 130 may be disposed between partially adjacent first heat dissipation fins 120, and some adjacent first heat dissipation fins 120 may not have any second heat dissipation fins 130 disposed therebetween; this invention is not limited to this. On the other hand, in this embodiment, the distance between adjacent first heat dissipation fins 120 and second heat dissipation fins 130 is equal. In other embodiments, the distances between adjacent first heat dissipation fins 120 and second heat dissipation fins 130 may not be equal. As long as the total spacing between adjacent first heat dissipation fins 120 and second heat dissipation fins 130 remains unchanged, the distances between adjacent first heat dissipation fins 120 and second heat dissipation fins 130 may be increased or decreased as needed.

[0039] As described above, in this embodiment, the first thickness D1 is 0.3 mm and the second thickness D2 is 0.2 mm. In other embodiments, the second thickness D2 may also be 0.1 mm, as long as it is less than the first thickness D1; ​​this is not a limitation. Furthermore, in this embodiment, both the first heat dissipation fins 120 and the second heat dissipation fins 130 are made of aluminum. In other embodiments, the first heat dissipation fins 120 and the second heat dissipation fins 130 may be made of other materials. Additionally, the first heat dissipation fins 120 and the second heat dissipation fins 130 may be made of different materials; this is not a limitation.

[0040] Please continue to refer to this. Figure 1A and Figure 1B In this embodiment, the heat dissipation element 140 includes at least one heat pipe 141, which penetrates the first heat dissipation fins 120 and the second heat dissipation fins 130 and extends outward from the heat dissipation fin assembly 100. Specifically, the heat dissipation fin assembly 100 is connected to a heat source (not shown) via the heat pipe 141, allowing heat from the heat source to be transferred to the first heat dissipation fins 120 and the second heat dissipation fins 130 via the heat pipe 141. The heat is then carried away by airflow passing through the first heat dissipation fins 120 and the second heat dissipation fins 130. In this embodiment, there are two heat pipes 141. In other embodiments, the number of heat pipes 141 may be one or more, and this invention is not limited to this.

[0041] Please refer to Figure 2 Another embodiment shown therein is similar to Figure 1A The embodiments are largely the same, the difference being that the heat dissipation element 140 includes a heat spreader 142 disposed at the end away from the opening 110a. Specifically, in this embodiment, the side of each of the first heat dissipation fins 120 away from the first side 121 is connected to the heat spreader 142 on the side of each of the second heat dissipation fins 130 away from the second side 131. In other embodiments, the heat spreader 142 may also be disposed on the side perpendicular to the first side 121 and the second side 131, as long as the heat spreader 142 is not disposed at the opening 110a and connects each of the first heat dissipation fins 120 and the second heat dissipation fins 130; this is not a limitation. When the heat dissipation fin assembly 100 is used to dissipate heat from a heat source (not shown), the heat spreader 142 is first brought into contact with the heat source, allowing the heat from the heat source to be transferred to the heat dissipation fin assembly 100 through the heat spreader 142. The heat source is then transferred to the first heat dissipation fins 120 and the second heat dissipation fins 130 through the heat spreader 142, and the heat source is carried away by the airflow as it passes through the first heat dissipation fins 120 and the second heat dissipation fins 130.

[0042] In summary, the heat dissipation fin assembly of this invention features two different thicknesses of heat dissipation fins arranged in an alternating pattern. This ensures that the total spacing between the heat dissipation fins in the assembly does not decrease, thus reducing noise generated by airflow as it passes through them and increasing the heat dissipation area, thereby improving heat dissipation efficiency. Furthermore, the thicker first heat dissipation fin is higher than the thinner second heat dissipation fin in the opening direction, effectively protecting the thinner second heat dissipation fin from bending or breakage when subjected to external force at the opening.

Although the 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 or all of the technical features therein.
