Description
技术领域
本发明涉及散热结构领域,特别是一种大功率LED灯多重散热结构。
背景技术
LED作为新一代绿色光源,环保型固体照明光源,己经成为人们关注的焦点,正在被广泛的应用于照明行业。它具有耗电量少、光色纯、全固态、质量轻、体积小、环保等一系列的优点。LED是个光电器件,其工作过程中只有15-25%的电能转换成光能,其余的电能几乎都转换成热能,使LED的温度升高。在大功率LED使用中,散热是个重要问题。例如,1个lOW白光LED若其光电转换效率为20,则有8W的电能转换成热能,若不加散热措施,则大功率LED的器芯温度会急速上升,当其结温上升超过最大允许温度时,高温会导致芯片射出的光子减少,色温质量下降,加快芯片老化,缩短器件寿命等严重的后果。因此在大功率LED灯具设计中,最主要的设计工作就是散热设计。如今国内对于LED散热系统的相关技术还不是很成熟,LED散热设计多采用铝散热鳍片来增加散热面积,这样的散热结构热阻较高,导热速度太慢,无法将大功率LED芯片在工作时产生的热量及时导出,散热效果不理想,发热体通常会达到较高的温度,减少了LED的使用寿命。
发明内容
本发明的目的在于克服现有技术的缺点,提供一种大功率LED灯多重散热结构。
本发明的目的通过以下技术方案来实现:一种大功率LED灯多重散热结构,包括外壳,所述外壳的底部设有LED光源,LED光源连接导热片,导热片与LED光源之间涂覆有导热涂层,所述的导热片连接散热片,散热片设置有多个且呈圆环状由内向外等距排布,散热片的侧壁上设置有多个散热孔,外壳内部中间的散热片的内腔设置有蛇形盘管,蛇形盘管的头端和尾端均连接冷凝液循环腔,所述的外壳后端设置有隔板,蛇形盘管与隔板连接,冷凝循环腔安装在隔板上,隔板中心处贯穿有转轴,转轴的上端设有电机,转轴的外部设置有多个叶轮,每个叶轮的外侧均固定连接有导风板。
具体地,所述的外壳的外壁一侧环绕设有若干个散热槽,每个所述散热槽内均垂直分布有若干个散热通孔。
具体地,所述的外壳顶部设置有一过滤网。
具体地,所述的转轴的外部环绕固定连接有2~4个导风板。
具体地,所述的隔板上设置有若干通风孔。
具体地,所述的散热片设置有3~6个,散热片为中空结构。
具体地,所述的冷凝液循环腔内设置有循环泵。
具体地,所述的转轴设置在蛇形盘管形成的中部空腔内。
本发明的有益效果如下:本发明通过多重散热将LED灯产生的热量排出,散热片的多层结构,增大了接触面积,有利于热量的传导,蛇形盘管能将不易排出的热量吸收,通过蛇形盘管内循环的冷凝水,电机带动转轴转动带动疏风板转动吸热同时将热量通过外壳上的散热通孔排出。
