Description

Annular aluminum alloy radiating fin structure

Technical Field

The utility model relates to the field of radiating fin production, in particular to an annular aluminum alloy radiating fin structure.

Background

The radiating fin is a device for radiating the heat-generating electronic element in the power supply, and is mostly made of aluminum alloy, brass or bronze into a plate shape, a sheet shape, a multi-sheet shape and the like, for example, a CPU central processing unit in a computer needs to use a quite large radiating fin, and a power tube, a row tube and a power amplifier tube in a television need to use the radiating fin. In use, a layer of heat-conducting silicone grease is coated on the contact surface of the electronic element and the heat sink, so that heat emitted by the element is more effectively conducted to the heat sink and then emitted to the surrounding air through the heat sink.

The performance of the heat sink is determined by the contact area between the heat sink and the air, the larger the area is, the higher the heat dissipation efficiency is, and on the contrary, the smaller the heat dissipation efficiency is, the heat dissipation efficiency of the existing heat sink is mostly improved by improving the contact area between the heat sink and the air, for example, an annular heat sink with the patent number 2021220364951 is to increase the heat dissipation efficiency by enlarging the heat dissipation channel area.

In the practical production and use process, although the radiating efficiency of the radiating fin is high, the radiating fin is thin, and the radiating fin is possibly deformed due to slight collision, so that the radiating efficiency is reduced, and therefore, the radiating fin is required to be firm in structure and cannot be deformed due to slight collision.
