Heat dissipation has become a major obstacle to the further development of the microelectronics industry. Fin heat sinks usually consist of fin components and heat source bases. The heat source base provides a place to contact the heat source, and then conducts the heat to the fins for heat dissipation to the air. The role of the fin is to transfer the heat to the air at the fastest speed, effectively dissipate the heat of the heat source, and keep the heat source working at a reliable temperature.

[0003] At present, the cooling fins of the inner fin air cooling device on the market are all fixedly installed.

The gap between the cooling fins cannot be adjusted according to different heat dissipation requirements, resulting in low practicality of the inner fin air cooling device. For this reason, we propose an inner fin air cooling device. Utility Model Content
