1,Superior cooling performance

　　??a,The raw material of cold forging heat sinks is 1070 pure aluminium, the thermal conductivity is 226 W/m.K, the thickness of the blades can be made to 0.6mm which increases the heat dissipation superficial area greatly.

　　b,While, the thermal conductivity is merely 96 W/m.K of the die casting products, its blades can’t?be made too more and too thin neither.

　　c,As to the lathe processing section aluminum heat sinks, the thermal conductivity is merely from 155 to 209 W/m.K, and it must be split-type, the joint will bring huge impact of the heat conduction performance, which result in the efficiency reduced about by 40 percent.

2,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 prevent

excessive temperature rise. The most common way?to do this is by using a heatsink
