The LED heatsink is a finned heat exchanger that mount on LED lighting to conduct heat from circuit and convect thermal to the surrounding air.
specification and application
Material of the heatsink is pure aluminum, and then black anodized. Therefore it has very good thermal conductivity. Secondly the excellent plasticity of pure aluminum 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 lighting industry, it also plays important role in electronic industry, and other sectors that has heat exchange requirements.
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, LED heatsink 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.
