Description

Technical Field

[0001] The utility model relates to the field of heat dissipation of electronic products, in particular to a heat dissipation fin assembly. Background Art

[0002] As the processing speeds of chips inside electronic products such as computers continue to increase, the heat generated by these chips during operation is also increasing. Therefore, a heat sink is needed to dissipate heat from these chips. Conventional heat sinks typically utilize a centrifugal fan, a heat sink assembly, and a heat pipe component to dissipate heat from these chips.

[0003] However, during use, as the fan power increases, high-speed airflow passing through the heat sink fins will generate a lot of noise, affecting user experience and resulting in a poor user experience. Utility Model Content

[0004] The purpose of the utility model is to provide a heat dissipation fin assembly, which greatly reduces the noise generated during use and improves the user experience of personnel.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a heat sink fin assembly, comprising: heat sink fins, a plurality of the heat sink fins are arranged in sequence, and a ventilation channel is provided between two adjacent heat sink fins, a plurality of through holes are spaced apart along the length direction of the heat sink fins, a protrusion is provided on the surface of the heat sink fin and covering the through hole, a first ventilation hole is formed between one end of the protrusion and the heat sink fin, a second ventilation hole is formed between the other end of the protrusion and the heat sink fin, and the first ventilation hole and the second ventilation hole are respectively connected to the through hole.

[0006] The further improved scheme in the above technical scheme is as follows:

[0007] 1. In the above solution, a plurality of first extensions are spaced apart on one side of the protruding piece, a plurality of second extensions are spaced apart on the other side of the protruding piece, and the through hole has communication areas corresponding to the first extensions and the second extensions respectively.

[0008] 2. In the above solution, the first extension portion and the second extension portion are staggered.

[0009] 3. In the above solution, the height of the first gasket is greater than the height of the protruding piece.

[0010] 4. In the above solution, a plurality of the protrusions are distributed at equal intervals along the length direction of the heat dissipation fins.

[0011] 5. In the above solution, the protruding piece is a copper sheet or an aluminum sheet.

[0012] 6. In the above solution, a first gasket is provided at each end of the heat dissipation fin.

[0013] 7. In the above solution, a second gasket is provided in the middle of the heat dissipation fins.

[0014] Due to the application of the above technical solution, the present invention has the following advantages and effects compared with the prior art:

[0015] The heat dissipation fin assembly of the present invention has a first ventilation hole formed between the front end of the protruding piece and the heat dissipation fin, and a second ventilation hole formed between the rear end of the protruding piece and the heat dissipation fin, and the first ventilation hole and the second ventilation hole are respectively connected to the through hole. When the airflow passes through the heat dissipation fin, a portion of the airflow passes straight through the ventilation flow channel between adjacent fins, and the other portion can flow into the adjacent ventilation flow channel through the guidance of the through hole, the first ventilation hole, and the second ventilation hole. This not only increases the heat dissipation area and improves the overall heat dissipation efficiency, but also helps to suppress turbulence and excitation noise generated by the gas flow by changing the speed and direction of part of the airflow, greatly reducing the noise generated by the heat dissipation fin assembly during use and improving the user experience. Furthermore, a plurality of first extensions are provided at intervals on the left side of the protruding piece, and a plurality of second extensions are provided at intervals on the right side of the protruding piece. The through hole has a communication area corresponding to the first extension and the second extension, respectively. The first extension and the second extension on the left side of the protruding piece cooperate with the communication area of ​​the through hole to divide the air into multiple flow areas, which helps to reduce the transmission of noise and further reduce the noise generated by the heat dissipation fin assembly.
