具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考附图详细描述根据本申请实施例的车辆1000的充电装置100。
如图1和图2所示，根据本申请实施例的车辆1000的充电装置100可以包括：散热主体10和充电连接件30，散热主体10内形成有冷却流道11，散热主体10上设置有安装座20，冷却流道11与安装座20内部连通，充电连接件30安装在安装座20上。也就是说，散热主体10上的冷却流道11流经安装座20，如此冷却流道11内的冷却介质可以在安装座20处与充电连接件30进行换热，从而可以有效降低充电连接件30的温度，可以降低充电连接件30的接线端子的温度，可以避免接线端子出现过热的现象，进而可以保证充电装置100的工作可靠性，可以保证车辆1000的充电安全性。其中，冷却介质可以为冷却水，也可以为其他冷却液。接线端子可以包括传输电流的正极接线端子 和负极接线端子。此接线端子适用于直流充电口。
同理交流充电口充电接线端子也是成对出现，可能为多个，原理同上，依旧可以实施应用。
如图1和图2所示，散热主体10包括：进管12、多个中间管13和出管14，多个中间管13并联在进管12和出管14之间，安装座20内的冷却流道11与至少一条中间管13内的冷却流道11连通。由此，多个中间管13可以共用一个进管12和一个出管14，这样可以使得散热主体10结构简单，易于布置。而且如此设置的散热主体10还可以保证各个中间管13的内的冷却介质流动平稳性。其中，安装座20内的冷却介质可以向中间管13流动，这样可以保证安装座20内的冷却介质的流入流出，从而可以保证安装座20内的冷却介质有效冷却充电连接件30。
如图1和图2所示，多个中间管13垂直于进管12和出管14设置。这样中间管13可以在竖向设置，进管12和出管14可以水平设置，从而可以保证中间管13内的冷却介质流动顺畅，而且可以有利于进管12和出管14同时与多个中间管13相对应。
如图3所示，中间管13包括：管体131和翅片132，管体131内形成有冷却流道11，翅片132设置在管体131的外周壁上。管体131的设置可以允许冷却介质在进管12和出管14之间流动，翅片132的设置可以提高管体131的散热面积，从而可以有利于安装座20与充电连接件30更好地换热。
其中，如图1和图2所示，安装座20的上端与进管12连通，而且安装座20的下端与多个中间管13连通。由此，一部分冷却介质从进管12流出后可以直接进入到安装座20内，并且在安装座20处与充电连接件30进行换热，从而可以有效降低充电连接件30的接线端子的温度，而且流出安装座20的冷却介质可以流入到中间管13内。而且一个安装座20可以同时对应多个中间管13，从而可以保证冷却介质的流动顺畅性。
根据本申请的一个具体实施例，安装座20包括：安装部21和套筒部22，套筒部22与安装部21相连，而且套筒部22的轴线垂直于安装部21的表面，安装部21安装在进管12和中间管13之间。可以理解的是，安装部21可以起到固定的作用，而且可以有利于冷却介质在安装部21内的流动，而套筒部22的设置能够便于安装座20固定充电连接件30。
如图5所示，安装部21内形成有冷却腔，冷却腔的上端与进管12固定且连通，冷却腔的下端设置有多个与中间管13对接的通过孔23。也就是说，安装部21内实质形成了一个腔室，腔室用于充满冷却介质，这样可以合理利用安装部21内的容积，可以提升安装座20与充电连接件30的接线端子的换热效果，可以有效降低接线端子的温度。
如图2和图4所示，安装部21上设置有多个安装柱24，安装部21和套筒部22处 形成有安装孔25，充电连接件30的一部分伸入安装孔25，而且多个安装柱24与充电连接件30相固定。充电连接件30上可以对应设置有穿孔，安装柱24伸入穿孔内并与其它紧固件固定，如此设置的安装柱24一方面可以保证充电连接件30和安装座20之间的安装可靠性，另一方面可以有效增加充电连接件30和安装座20之间的接触面积，可以有效降低充电连接件30的接线端子的温度。
其中，如图2所示，安装柱24为多个，而且多个安装柱24围绕安装孔25设置。这样多个安装柱24可以更好地提高充电连接件30在安装座20的安装可靠性。
如图所示，根据本申请实施例的车辆1000，可以包括上述实施例的车辆1000的充电装置100和冷却系统40，冷却流道11适于串联在车辆1000的冷却系统40内。由此，冷却流道11内可以流动有冷却水，车辆1000可以在车辆1000充电时控制冷却系统40的开启，从而可以有效降低充电连接件30的工作温度。
如图6所示，冷却系统40可以包括：泵体210、换热器220和储液罐230，泵体210、换热器220、储液罐230、冷却管路40和冷却室20串联连接，其中，泵体210与换热器220相连，储液罐230与换热器220相连，而且储液罐230还与冷却流道相连，冷却流道还与泵体210相连。由此，泵体210可以在充电插座10和充电桩600上的充电枪610对接时工作，从而将冷却液泵入冷却流道、冷却管路40和冷却室20，以使得冷却流道冷却接线端子2和充电线束30。冷却系统40还包括：过滤器240，过滤器240设置在泵体210和换热器220之间，过滤器240可以起到过滤作用。
如图6所示，车辆1000还可以包括：插接检测件50和电控模块60，插接检测件50用于检测插入充电连接件30内的充电枪81插接状态，电控模块60与插接检测件50电连接且在接收到充电枪81插接完成信号后控制泵体41工作。其中，如图6所示，充电连接件30还可以包括：配电模块70，配电模块70可以向电控模块60配电，而且电控模块60控制泵体41的工作状态。由此，充电连接件30可以实现合理控制的目的，在充电时可以保证冷却流道11内流动有冷却介质。
