高效率铜铝复合散热器及材料参数对比 - The thermal conductivity of cu/al composite materials

铜铝复合散热器其应用中表现的主要特点如下：
⑴．铜铝复合散热器，充分发挥了铜材的导热性能，把热源的热量导出性能的优点。
⑵．充分发挥了铝材散热性能好、质轻的优点，既实现了高能量密度的微型化，也实现了散热系统的轻量化。
⑶．铜铝之间实现冶金结合，且铜铝中间不存在接触热阻，减少了传热界面，大大提升了系统的散热效率。综合散热效率较纯铜更高。

Main characteristics of copper clad aluminum composite radiators:

(1) copper clad aluminum composite radiators can give full play to the thermal conductivity of the copper material and derive the heat from the heat source.

(2) To exert good heat dissipation and light weight of aluminum, realized the miniaturization of high energy density, also to achieve the lightweight of thermal system.

(3) Metallurgical bonding is realized between copper and aluminum, no contact thermal resistance between copper and aluminum, which reduces the heat transfer interface and greatly improves the heat dissipation efficiency of the system. The comprehensive heat dissipation efficiency is higher than that of pure copper.
