【应用】导热凝胶GEL30解决智能眼镜盒充电时热积聚问题
智能眼镜是一个新兴的产品,一个眼镜集合了听音乐、打电话、导航、看视频甚至玩游戏等很多功能,而且还耽误耳朵接听外界的信号,刚一出现就受到很多数码爱好者的追捧。智能眼镜工作时,是由自身配备的电池供电,不用的时候可以放到智能眼镜盒中进行无线充电,而眼镜盒本身也是配备一定容量的电池,在电池有电的时候可以直接给智能眼镜充电,当智能眼镜盒电池电量偏低时也需要通过外接数据线给智能眼镜盒充电。
控制这些充电逻辑和智能眼镜盒的其他功能都是通过眼镜盒里面的控制板来实现的,控制板上集成很多控制芯片,有射频微控制器芯片、蓝牙SOC等等。由于智能眼镜盒是无线充电,且能通过蓝牙控制,所以控制板上的芯片都罩上了屏蔽罩来降低电磁干扰。
虽然电磁屏蔽通过屏蔽罩解决了,但是同时又带来了另一个问题,那就是热量积聚问题。由于智能眼镜盒的体积不大,且里面大面积背电池占据,导致智能眼镜盒内的空间十分狭小,再者芯片都被屏蔽罩盖上导致芯片产生的热量积聚散热不通畅。此时可以在发热的芯片上面点上PARKER CHOMERICS的导热凝胶THERM-A-GAP™ GEL30,通过导热凝胶把热量导到金属屏蔽罩上,通过屏蔽罩来把芯片产生的热量散到外界中去。Parker Chomerics GEL30,导热系数3.5W/m.K,流速20g/min,无需人工打胶,可用点胶机连续作业,非常适合智能眼镜盒等消费电子的生产工艺。
