【应用】挥发性低的导热凝胶GEL20用于车载显示屏散热设计,导热系数2.4W/m-K,挥发性小于0.12%TML
车载显示屏主要应用在中控屏、组合仪表盘、娱乐系统等汽车内饰,目前业内主流还是液晶LCD方案,长期工作导致的温度升高会影响显示屏工作的稳定性,需要合理的散热解决方案。
针对汽车显示屏的散热设计应用,推荐PARKER CHOMERICS的单组分导热凝胶GEL20,导热系数2.4W/m-K,最小间隙0.1mm,流胶速度25cc/分钟,以下是GEL20典型性能参数:
优势如下:
1、车载显示屏一般是液晶材质,正常工作需要驱动芯片来调节发光强度,长期工作在汽车环境,热量堆积会影响显示屏的性能和寿命,由于是在车内工作,发热量不高,推荐采用GEL20系列导热凝胶用于散热,其相比导热垫片,具有更好的表面亲和性,导热系数达到2.4W/m-K,满足车载显示屏驱动芯片的散热需求。
2、车载液晶显示屏的驱动芯片和控制芯片都需要散热设计,GEL20导热凝胶的最小厚度只有0.1mm,流胶速度达到25cc/min,利用点胶机可实现受控分配,满足不同厚度芯片的散热需求。
3、车载显示屏涉及到部分光学器件,易收到硅油等挥发物影响,导热凝胶GEL20的挥发性仅为0.12% TML,可保证光源不受污染,提高显示屏发光亮度的稳定性,同时满足UL 94V0防火认证。
综上所述,Parker Chomerics的GEL 20单组分导热凝胶具有2.4W/m-K导热性能、流胶速度25cc/分钟、低挥发性、可采用点胶机批量生产加工的特性,是车载显示屏散热设计的优秀解决方案。
