优选的，铝制散热片的厚度在0.1-2.5mm之间。
优选的，当LED汽车头灯散热装置包括至少两组鳍片式散热片组时，鳍片式散热片组均匀周向排列。
优选的，当LED汽车头灯散热装置包括两组鳍片式散热片组时，两组鳍片式散热片组呈一字设置。
优选的，当LED汽车头灯散热装置包括四组鳍片式散热片组时，四组鳍片式散热片组呈十字设置。
优选的，鳍片式散热片组设置在散热座的侧壁，散热座的轴线位置设有定位孔，LED汽车头灯设置在定位孔内，散热座由铝材料制成。
优选的，散热座由多个铝块自上而下通过紧固件连接而成，每一鳍片式散热片组的至少两片铝制散热片的一端与多个铝块的侧壁一一对应连接。
采用以上技术方案的有益效果是：本发明结构的LED汽车头灯散热装置，该鳍片式散热片组用在LED汽车灯可以解决灯的无法变形，不可以有效利用汽车灯光总成的空间等缺陷；可以充分利用鳍片式散热片组的变形充分利用汽车灯总成的有限空间，并提高散热性能。

鳍片式散热片组1设置在散热座的侧壁，散热座的轴线位置设有定位孔4，LED汽车头灯3设置在定位孔4内，该散热座由铝材料制成。
散热座由多个铝块5自上而下通过螺栓6固定而成，铝制散热片2设置在两个铝块5之间；铝制散热片2上设有通风孔7，铝制散热片2上设有限位块8。
本发明结构的LED汽车头灯散热装置，该鳍片式散热片组用在LED汽车灯可以解决灯的无法变形，不可以有效利用汽车灯光总成的空间等缺陷；可以充分利用鳍片式散热片组的变形充分利用汽车灯总成的有限空间；散热片增加通风孔、限位块令鳍片式散热片组不易叠加在一起。
还需要说明的是，与现有的柔性散热带相比，柔性散热带的成本不易控制、性能不稳定，材料成型高，加工程序复杂，本申请实施例中的LED汽车头等散热装置中的鳍片式散热片组成本低，获取容易，加工简易，可以降低加工成本，提高生产效率。
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
