High-efficient forced air cooling fin structure

Technical Field

The utility model relates to a radiator technical field, concretely relates to high-efficient forced air cooling fin structure.

Background

In the radiator industry, most of the air-cooled radiating fins are straight teeth, wave teeth, staggered teeth and the like. Taking an air-cooled fin radiator as an example, the fin radiator is generally formed by punching an aluminum plate, and meanwhile, the fin is also often provided with section corrugated teeth, hollow section corrugated teeth and the like, and the change of the tooth shape state is only to increase the heat dissipation area so as to indirectly improve the performance of the radiator.

The current production of air-cooled radiators reaches certain bottlenecks: under the conditions of weight limitation, size limitation and process limitation, the heat dissipation area of the heat sink is difficult to be increased by increasing the number of fins of the heat sink, otherwise, the heat dissipation area needs to be realized at a huge cost. The improvement of the heat dispersion of radiator, the way has the multiple: increasing the radiating fins of the radiator to increase the radiating area; the flow state of the cooling medium in the radiator is changed. The shape of the fin of the radiator is changed to change the flowing state of the fluid in the radiator, so that the radiating performance of the radiator is improved.
