导热垫片、导热凝胶、U形金属块,源阳热能,鸿富诚,Parker Chomerics

世界上最好的导热材料是石墨烯，其次是钻石，然后是金属，再就是石墨，导热垫片和凝胶，最后是空气。光模块中导热材料的使用不仅要考虑导热性能，还要考虑成本，所以光模块中优先使用的是空气，其次是导热垫片和凝胶，然后是普通金属，石墨，再就是贵金属，最后是钻石和石墨烯。

光模块中发热源主要是芯片和TOSA等地方，这些地主的热量则需要通过导热材料散出去。

1、空气：

空气的导热系数只有0.023W/mK，模块高温工作时，如果仅依靠空气对流则内部激光器芯片温度会非常高，下面是某款未加散材料的模块设计，模块75度，内部激光器芯片温度则高达在92.8度，很影响长期可靠性。

通常光模块内部，热量不高的地方用空气散热，热量高的地方需要考虑其他导热材料。

2、导热垫片

导热垫片的导热系数约1～10W，鸿富诚，莱尔德等都有常用于光模块的导热垫片，导热垫片是片状的，具有一定的压缩性，为的是方便介质之间的充分接触。没接触好，就意味着用空气导热，充分接触，一般要施加外力，有压力，就会导致形变，厚度被压缩，压力越大一般热阻越小，导热效果也就越好（如下图），但如果压力太大导致形变剧烈的话，有可能会导致光路的耦合效率出现偏离。不过导热垫片使用简单方便，性价比高，为大部分客户首选。

3、导热凝胶

导热凝胶的导热系数约1～8W，世强有代理固美丽和莱尔德等常用于光模块的导热凝胶，导热凝胶是牙膏状的，材质很软，所以不需要太大的外界压力，不会对光路造成影响。其对界面的浸润效果非常好，而且可以压缩至非常低的厚度，使传热效率显著提升。另外导热凝胶可以任意成型成想要的形状，对于不平整的PCB板和规格器件均能保证良好的接触，同时导热凝胶可以自动化操作，节省人工同时提升生产效率。

4、U形金属块（铜块或铝块）

金属铜块或铝块导热系数237～401W/mK，世强有代理源阳热能的金属块，光模块上用金属导热的不多，有一个地方一般会用到金属，从TOSA到管壳是个U型的金属块，来贴合TOSA与光模块外壳。

TOSA一般是圆弧形的，如果不加U型金属块，则与外壳接触面积太小，散热不充分，热量聚集，激光器上的温度会非常高，加了金属铜块或铝块则温度能迅速降下来。像这种金属块一般重量会比较大，而且需要开模，成本会比较高一些。

5、高导热石墨

石墨的原子是碳，钻石的原子也是碳，只是他们的排列方式不同。石墨的排列，是一层层的，每层之间很容易分离。

所以石墨的水平方向，与垂直方向的导热能力不同

水平方向的石墨，单层石墨就叫石墨烯，导热系数能达到5300W/mK，导热效果非常好，但高导热的石墨烯技术，目前发展还不够成熟，成本也比较贵。光模块外壳是锌合金，导热系数一般不到100W/mK，如果外壳上贴一层高导热的石墨，则可以把局部集中的热量迅速的传导至温度低的地方，实现均温效果。
