LED Downlight Anodized Heat Sink Extruded With ISO Approval OEM

LED Downlight Anodized Heat Sink Extruded With ISO Approval OEM

Extruded  Aluminum Round LED Downlight Shell Heatsink Made by a ISO9001 Factory .We  engaged in manufacturing a comprehensive array of Aluminium Heat Sinks. The primary purpose of a heat sink is to maintain the device temperature below the maximum allowable temperature specified by the device manufactures. Most of the heat sinks have fins or ridges, which are used to increase the surface area that allows more metal to come into contact with the air, which allows the heat to be dissipated more quickly.

Great Heat Dissipating Capacity of Aluminum LED Downlight Heat Sink , this item has great heat dissipating capacity .As you can see in the pictures , we add more fins and make the fin more thiner which developing the dissipating capacity .

Description:
 

All semiconductor devices have some electrical resistance, just like resistors and coils, etc. This means that when power diodes, power transistors and power MOSFETs are switching or otherwise controlling reasonable currents, they dissipate power . as heat energy. If the device is not to be damaged by this, the heat must be removed from inside the device (usually the collector-base junction for a bipolar transistor, or the drain-source channel in a MOSFET) at a fast enough rate to preventexcessive temperature rise. The most common way to do this is by using a heatsink
