优选的,所述外壳底部与棱镜式反射支架底部一侧对应开设有进气口,所述进气口内嵌设有进气管,所述外壳顶部中心与棱镜式反射支架顶部中心通过出气口连通。
优选的,所述出气口内嵌设有防尘网。
优选的,所述第一隔离网为HEPA滤网,所述第二隔离网为活性炭滤网。
优选的,所述第一隔离网设置于第二隔离网下方。
优选的,所述外壳内嵌设有导热硅胶层。
与现有技术相比,本发明的有益效果是:
金属散热片根据热力环流原理在环流腔内产生空气对流,而外壳外部空气为冷空气,同样根据热力环流原理产生空气对流,导入冷空气,带出棱镜式反射支架内的热空气,加快UV LED灯杀菌速度,气体流通的同时,可以利用空气导热的原理,同时给电子元器件散热,延长产品寿命。
