The pin fin heat sink is a finned heat exchanger that mount on electronic device to conduct heat from circuit and convect thermal to the surrounding air.

specification and application

Material of the heatsink is pure aluminum. Therefore it has very good thermal conductivity. Secondly the excellent plasticity of material makes it possible to cold extrude the pin fin profile. As a result, pin fin structure maximize thermal convection rate and efficiency.

Generally speaking, pin fin heat sink has broad application in many industry area. As well as electronic industry, it also plays important role in LED lighting industry, and other sectors that has heat exchange requirements.

Working Mechanism

In field application, heatsink thermal conduction surface contact with thermal source area. So, it is very important to make sure that the contact surface is flat as much as possible. Usually it is necessary to add thermal paste between contact area to squeeze out the air that is trapped in irregular space.

In conclusion, pin fin heat sink is a heat exchanger component that has wide application in many industry area, the selection of material and manufacturing process has great impact on its function.
