Competitive Advantage:

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,Economize the product’s cost, improve product& acute;s service life

a,When the production volume is? large, the cost is lower than lathe processing heat sink, what’s more, the common section aluminum heat sink are split-type, so it have to involve in artificial assembly costs.

b,We made a comparison in the common lathe processing section aluminum heat sinks, die casting heat sinks and cold forging unibody type heat sinks:

①,In the addition of the same size and shape, the cold forging unibody type heat sinks can be applied on bigger power appliance than the other heat sinks. For example, the common lathe processing section aluminum lamp cups can be only used for cooling the 3W bulb, but our heat sinks can be used for cooling 5W bulb. If the common heat sinks applied on the cooling of 5W bulb, the material and size must be added, the cost will higher than the cold forging unibody type heat sinks much more.

②,The more worthy of praise, if you put our products and common heat sinks on the same power bulb respectively, you can find that own to the excellent radiation capacity, the temperature of the bulb which used our heat sinks is sharply lower than the others,which expanded the service life of the appliance obviously.

3,Appearance texture superexcellence

The surface of this new type heat sinks can be taken anodic treatment, but the die-casting products can’t be treated with such technique but baking finish, due to expansion caused by heat and contraction caused by cold, the paint may split away off little by little, on the other hand, the paint will restrain the radiation and diffusion of the heat, which not only affect the appearance texture but also reduce the cooling efficiency.
