Description

车灯散热器 技术领域
本发明涉及散热器领域，具体是指一种车灯散热器。
 背景技术
车灯在照明时需要通过散热器将热量及时排出，目前市场上现有的散热器大部分为鳍片式散热器或者柱状散热器，鳍片式散热器只有单一方向的散热通道，散热效果不佳，而且整体重量较重，经过改进后，出现了柱状散热器，柱状散热器虽然重量降低，散热通道增加，但是由于柱状散热器上的散热柱布设较密，散热效果也为达到预期效果。
 技术解决方案
本发明要解决的技术问题是针对上述现有技术的不足，而提供一种车灯散热器。
为解决上述技术问题，本发明采用的技术方案是：  
一种车灯散热器，包括散热底板，散热底板表面设置有若干列相互平行排列的散热片，每列散热片之间预留有散热通道一，每列散热片之间顺序排列形成若干排散热片，每排散热片之间预留有散热通道二；所述散热片的横截面呈波浪形。
进一步的，所述散热底板与散热片由模具冷锻成型。
进一步的，所述散热底板上加工有安装孔和避让孔。
进一步的，所述散热片侧面设置有弧形凸起。
 有益效果
与现有技术相比，本发明的一种车灯散热器，在散热底板上均匀布设散热片，散热片之间预留有散热通道，散热通道提高了散热效率，散热片采用波浪形状，强度高，不易弯曲，而且整体重量下降，降低了制造成本。
