Description

Technical Field

[0001] The utility model relates to the field of heat dissipation devices, in particular to a heat dissipation fin high-efficiency heat dissipation structure. Background Art

[0002] A heat sink is a heat dissipation device used to dissipate heat from electronic components. It is usually widely used in the field of liquid cooling. Most of the existing liquid cooling heat sinks include a heat sink base and a heat pipe. The heat pipe is arranged at the heat sink base to dissipate heat from the heat pipe, and then the heat is dissipated from the high-temperature liquid in the heat pipe, so as to finally realize liquid cooling circulation heat dissipation and achieve the heat dissipation purpose. However, due to the different contact areas between the heat pipe and the heat sink base, the heat dissipation efficiency of various types of heat sinks varies, but they are ultimately restricted by the heat conduction efficiency. The heat conduction efficiency between the heat pipe and the heat sink base is different between materials, which greatly restricts the heat dissipation effect of the heat sink, so it needs to be improved.

[0005] Specifically, a partition is provided in the heat dissipation slot, the first through hole and the second through hole are respectively provided at the same end of the heat dissipation base, and the first through hole and the second through hole are located on both sides of the partition.

A heat dissipation groove 12 is provided at the heat dissipation base 10. The heat dissipation element 11 is welded in the heat dissipation groove 12. The ends of the heat dissipation base 10 are respectively provided with a first through hole 13 and a second through hole 14. The first through hole 13 and the second through hole 14 are not communicated with each other, and the first through hole 13 and the second through hole 14 are both communicated with the heat dissipation groove 12. By providing the heat dissipation groove 12 at the heat dissipation base 10, and then providing the heat dissipation element 11 in the heat dissipation groove 12, by providing the first through hole 13 and the second through hole 14 at the heat dissipation base 10, circulating coolant is injected into the heat dissipation groove 12 through the first through hole 13 and the second through hole 14, the heat dissipation element 11 is directly in contact with the coolant, and then the heat conduction efficiency of the heat dissipation element 11 is improved to improve the heat dissipation effect.

In this embodiment, a partition 15 is provided in the heat dissipation slot 12, and the first through hole 13 and the second through hole 14 are separated by the partition 15, and a heat dissipation channel is formed in the heat dissipation slot 12. When the heat dissipation fins 17 of the heat dissipation element 11 are located in the heat dissipation slot 12, when the coolant flows from the first through hole 13 to the second through hole 14, the coolant flows along the heat dissipation channel and contacts the heat dissipation fins 17, thereby quickly taking out the heat of the heat dissipation element 11 to achieve a heat dissipation effect, and at the same time, the direct contact between the coolant and the heat dissipation element 11 effectively improves the heat conduction efficiency, and greatly improves the heat dissipation effect.
