冷挤压一体式散热器产品的优势

1、  散热性能优越

  a、冷挤压散热器材质为1070纯铝，导热系数为226m.k，叶片可以做到0.7厚，增加产品热辐射表面积；

b、而同为一体式的压铸产品材质的导热系数只有96m.k，而且叶片不能太薄太多；

c、车制铝型材的导热系数只有155-200m.k，且铝型材的散热器是分体式的，接缝对热传导影响很大，只为同类型材质一体式产品的约60%。

2、节约产品成本，提高产品寿命

a  产品量大时比铝型材车制产品成本更低，同时常规铝型材车制产品是灯杯灯盖分体式的，要组装起来也需要增加装配人工成本；

b、相比较常规铝型材车制散热器及铝合金压铸散热器：

①、同样体积形状的一体式散热器，可用于更大功率产品的散热（比如：某一款常规铝型材车制散热灯杯只能用于3W灯泡的散热，而同样形状大小的一体式散热灯杯则可用作5W灯泡的散热；而如果常规散热器要用作5W灯泡散热则需增加体积，成本会比一体式散热器增加很多）;

②、而如果两款同样体积形状的冷挤压一体式散热器和常规铝型材车制散热器用在相同功率的灯泡上，用一体式散热器的产品内积温将大大降低，可大幅提高产品使用寿命。

3、  外观质感优

一体式散热器表面可做阳极处理，压铸产品表面不能做阳极处理，只能烤漆，由于热胀冷缩产品用一段时间后油漆可能会掉，同时油漆也会抑制热量的幅射扩散，既影响外观质感又影响散热。

The strengths of cold forging unibody type pure aluminium heat sinks

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'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.
