Technical Field

[0001] The utility model relates to the field of heat dissipation fin design, and more specifically to a liquid-cooled heat dissipation fin structure. Background Art

[0002] Conventional liquid-cooled fin (FIN) designs often use the shovel FIN process. Conventional liquid-cooled fins are all made by a one-piece forming method, and the fins are all arranged in a parallel manner as a whole piece.

[0003] However, in recent years, the power consumption TDP of CPUs and GPUs has been increasing year by year. Therefore, there is a higher demand for heat dissipation effects, and thus it is urgent to improve conventional liquid-cooled fins. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a liquid-cooled heat dissipation fin structure.

[0005] The technical solution of the utility model is as follows:

[0006] The liquid-cooled heat dissipation fin structure includes a fin base and a heat sink group arranged on the fin base; in the liquid flow direction, the heat sink group is composed of a plurality of horizontally arranged heat sink groups arranged longitudinally; the horizontally arranged heat sink group is composed of a plurality of sub-heat sinks arranged horizontally and evenly; the positions of two adjacent horizontally arranged heat sink groups are staggered, that is, the sub-heat sinks in the latter row are directly opposite the middle of two adjacent sub-heat sinks in the previous row.

[0007] The technical effects and advantages of the utility model:

[0008] This design structure increases the fin contact area, increases the water resistance, increases the water flow stagnation time, enables the fins to take away more heat, and achieves the purpose of improving the heat dissipation performance. Description of the Drawings

[0011] The technical solutions in the embodiments of the utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0012] Liquid-cooled heat dissipation fin structure, including a fin base 1 and a heat sink group 2 arranged on the fin base; in the liquid flow direction, the heat sink group is longitudinally arranged by a plurality of horizontally arranged heat sink groups 21 (such as Figure 2 within the dashed box in the figure) longitudinally arranged; the horizontally arranged heat sink group is composed of a plurality of sub-heat sinks 22 arranged horizontally and evenly; the positions of adjacent two horizontally arranged heat sink groups are staggered, that is, the sub-heat sinks in the latter row are directly opposite the middle, i.e., the half-way point, between two adjacent sub-heat sinks in the previous row.

[0013] The design structure of a plurality of sub-heat sinks increases the fin contact area and improves the heat dissipation performance;

[0014] The positions of adjacent two horizontally arranged heat sink groups are staggered, which can increase the water resistance and the water flow stagnation time, so that the fins can take away more heat to achieve the purpose of improving the heat dissipation performance.
