具体实施方式
下面结合附图对本实用新型的较佳实施例进行详细阐述，以使本实用新型的优点和特征能更易于被本领域技术人员理解，从而对本实用新型的保护范围做出更为清楚明确的界定。
具体实施例1：
如图1至图5所示，一种电动车散热防水充电器，包括一种电动车散热防水充电器，其特征在于：包括上壳1、下壳2、电线3、散热结构4；所述的上壳1侧面设有通风孔12；
所述的下壳2内分别对称设有两个第一筋板24和两个第二筋板23，所述的第二筋板顶部设有电路板21，所述的电路板21下面设有散热结构4；
所述下壳一侧的第一筋板24与下壳2底面之间的间隙高度为H1，所述下壳另一侧的第一筋板24与下壳2底面之间的间隙高度为H2，且H2>H1；
所述第二筋板23设有连通孔，所述连通孔位于靠近电路板的一端；
所述的散热结构4由导热底板41、传热铜管42、散热鳍片43组成，所述的导热底板41位于电路板21下方，所述的传热铜管42嵌于所述的导热底板41内，所述的散热鳍片43与所述的传热铜管42连接；
所述的导热底板41与所述的电路板21之间一侧涂有导热层，所述的导热层厚度为0.1-0.3mm。
具体的，所述的上壳1两端分别连接电源线。
具体的，所述的上下壳1，2接缝处设有密封圈。
具体的，所述的散热鳍片43等间距垂直分布在导热底板41上，每两片散热鳍片43的间距为4-6mm。
具体的，所述的通风孔12上设有遮雨盖11。
具体的，所述导热层为7762导热膏层。
工作原理：
充电器工作时，(参考图4)气流从左侧通风孔进入，向下流动，绕行后进入散热结构空间，而H1与H2是不一致的，且H2>H1,所以会形成气流差，产生循环流动，气流差使得气体从右侧出去，并循环此过程，而在散热结构空间 内部，导热膏层将电路板的热量快速通过传热铜管传到散热鳍片上，而散热鳍片将热量均匀的传到鳍片各个位置，增大了散热接触面积，从而实现快速散热，而这种气流通道，水分是进不来的，即使进来也会下沉到底部，而上下壳之间设有密封圈，通气孔也设有遮雨盖，所以当遇到下雨时或者淋水时，只能通过气流，而不会进入水分。
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
