如图3和图5所示，根据本申请实施例的充电装置100可以包括：充电连接件20和散热器10，散热器10内形成有安装孔13，充电连接件20安装在安装孔13内。可以理解的是，散热器10不仅可以起到为充电连接件20散热的作用，还可以起到固定安装充电连接件20的作用。其中，充电连接件20可以为充电插座，也可以为充电枪610。
下面详细描述一下充电连接件20的散热器10，充电连接件20的散热器10指的是该散热器10可以用于给充电连接件20散热。
根据本申请实施例的充电连接件20的散热器10可以包括：散热底座1，散热底座1包括：底壁11和周壁12，底壁11连接在周壁12的底部，而且底壁11上设置有安装孔13，安装孔13用于安装充电连接件20。也就是说，底壁11可以用于安装固定充电连接件20，周壁12可以与其他部件进行固定连接，例如，如图3和图5所示，充电装置100还可以包括：车身蒙皮40，周壁12的顶部可以连接至车身上，例如，周壁12的顶部可以固定在车身蒙皮40上，这样周壁12可以起到安装散热底座1和充电连接件 20的作用，而且散热底座1可以将热传递到车身上，以通过大面积的车身来散热，从而可以进一步的提升散热效果。需要说明的是，散热底座1具有散热的作用，周壁12的设置至少一定程度上增加了散热底座1的散热面积。
其中，周壁12在远离底壁11的方向上横截面积呈递增趋势，这样可以进一步的增加周壁12的表面积，可以提升散热底座1的散热效果。
另外，散热底座可以为导热材料。采用导热材料可以使得散热底座的散热效果好，而且可以有利于充电连接件的有效散热。
如图1、图2和图4所示，周壁12上可以设置有散热片14。散热片14可以提升散热底座1的散热效果，而且散热片14可以允许周围气体流动，从而可以使得气体带走充电连接件20的热量，进而可以更好地降低接线端子的工作温度。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。
在一些实施例中，如图1和图2所示，散热片14为多个，而且多个散热片14在周壁12的周向间隔开设置以构成周壁12的悬臂梁结构，这样可以保证周壁12的结构强度，而且可以在相邻的散热片14之间形成间隙以通风，此外，还可以增加周壁12与空气接触的表面积，从而加快散热。例如，多个散热片14可以间隔开设置以构成散热底座1的周壁12，此时的周壁12相当于底壁11的悬臂梁，如此设置的多个散热片14可以使得散热底座1的散热效果好，而且可以使得散热底座1制造简单，成本低。根据图4可以看出，散热片14还可以是周壁上开设多个散热长条孔以形成的散热片。
当然散热器10还可以包括其他部件，例如，第一冷却管路2，第一冷却管路2设置在散热底座1上，而且第一冷却管路2在散热底座1上延伸。也就是说，第一冷却管路2可以在散热底座1的底壁11上延伸，第一冷却管路2也可以在散热底座1的周壁12上延伸，第一冷却管路2也可以在散热底座1的底壁11和周壁12上延伸。第一冷却管路2具有冷却充电连接件20和散热底座1的作用，这样通过第一冷却管路2和散热底座1的结合，可以有效降低充电连接件20的温度，而且可以有效避免充电连接件20的接线端子出现过热的问题，从而可以保证车辆1000的充电安全性。
第一冷却管路2在周壁12的周向绕设至少一圈，以及在底壁11上绕设至少一圈。也就是说，第一冷却管路2可以在周壁12的周向方向上绕设一圈，或者，第一冷却管路2可以在周壁12的周向方向上绕设多圈。由此，第一冷却管路2在周壁12上布置合理，可以降低其对散热底座1的影响，而且这样第一冷却管路2也可以较好地与周壁12进行接触，从而可以提升换热效果。另外，多圈绕设的第一冷却管路2长度适宜， 可以增加其与周壁12之间的接触面积，可以进一步的增加换热效果。
根据本申请的一个可选实施例，如图1和图2所示，散热器10还可以包括：第二冷却管路3，第二冷却管路3设置在底壁11的后侧，即与周壁12分别位于底壁11的两侧，其中周壁12从底壁11处向前延伸，第二冷却管路3可以从底壁11处向后延伸。
而且，第二冷却管路3适于绕设在充电连接件20的充电线束30上，发热量大的充电线束30有两根，第二冷却管路30分别绕设在该两根充电线束30上，优选的，绕设在两根充电线束30上的第二冷却管路30连通，或者，绕设在两根充电线束30上的第二冷却管路30可以为一条，第二冷却管路3与第一冷却管路2连通，这样第二冷却管路3与第一冷却管路2可以共用进液口和出液口。也就是说，第二冷却管路3可以起到冷却充电线束30的作用，这样通过第一冷却管路2和第二冷却管路3的结合，可以降低充电连接件20的接线端子的温度的同时，还降低充电线束30的温度。另外，由于第一冷却管路2和第二冷却管路3连通，这样第一冷却管路2和第二冷却管路3可以共用一个冷却源，从而可以使得充电装置100结构简单，工作可靠。
第一冷却管路2和第二冷却管路3可以为铜管。铜管结构简单，易于与外界换热，从而可以更好地降低充电连接件20的温度。第一冷却管路2和第二冷却管路3可以均为圆形管，或者第一冷却管路2和第二冷却管路3可以为扁平管，这样可以便于第二冷却管路3绕设充电线束30。
第一冷却管路2和第二冷却管路3可以为一体管。这样可以降低第一冷却管路2和第二冷却管路3的布置难度，而且可以降低第一冷却管路2和第二冷却管路3的成本。
根据本申请的一个可选实施例，如图4所示，第一冷却管路2具有进液口和出液口，进液口和出液口彼此邻近设置。由此，这样可以使得第一冷却管路2进液和出液方便，而且可以便于冷却源的布置，可以有利于第一冷却管路2和冷却源之间的冷却液的循环，从而可以降低第一冷却管路2的布置难度。
在一些实施例中，如图7所示，还包括：外接头50，外接头50内设置有两个接口，两个接口分别与进液口和出液口连接。接口可以方便第一冷却管路2的进液口和出液口与对接头620对接，从而仅通过一个对接头620与一个外接头50对接即可完成冷却液的流通，使得第一冷却管路2的进液和出液方式简单且可靠。
其中，如图3和图5所示，充电装置100还可以包括：车身蒙皮40，散热底座1的周壁12固定在车身蒙皮40上，外接头50固定在车身蒙皮40上。如此设置的外接头50固定方式可靠，而且可以有利于其与外部冷却接头对接，从而可以使得第一冷却管路2的进液和出液简单方便。
如图3和图5所示，车身蒙皮40设置有散热条41。车身蒙皮40上的散热条41也 可以起到散热作用，这样可以进一步的降低充电连接件20的温度，可以避免接线端子出现过热的问题。
另外，车身蒙皮40上还可以设置有冷却流道，冷却流道与第一冷却管路2连通。
充电连接件20内形成有冷却流道，例如，充电连接件20内设置有冷却管路，冷却管路形成供冷却液流动的冷却流道，冷却流道与第一冷却管路2连通。如图8所示，外接头50的两个接头与充电连接件20的冷却流道之间连接有进液管路21和回液管路22。也就是说，充电连接件20的内部还可以设置冷却流道，冷却流道的设置可以直接且更加有效地带走接线端子的热量，从而可以保证车辆1000的充电安全性。
其中，如图8所示，充电连接件20为两个，进液管路21和两个充电连接件20的冷却流道之间连接有共用分液管23，出液管路22和两个充电连接件20的冷却流道之间连接有共用分液管23。共用分液管23可以解决两个充电连接件20内的冷却流道与进液管路21的连通，以及与回液管路22连通的技术问题，从而可以使得充电装置100整体结构简单且可靠。
共用分液管23呈U形。U形的共用分液管23可以有利于其同时向两个充电连接件20内的冷却流道供入冷却液。
还有，充电连接件20还可以包括：壳体24和封盖25，封盖25固定在壳体24的后部，冷却流道设置在壳体24内，共用分液管23的端部伸入封盖25内以与冷却流道连接。封盖25可以起到固定共用分液管23的作用，而且可以保证共用分液管23与进液管路21之间的连通密封性，以及共用分液管23与回液管路22之间的连通密封性。
其中，如图3和图5所示，充电连接件20可以为两个，用户可以根据需要选取其中一个充电连接件20使用。两个充电连接件20共用一个进液管路和一个出液管路。由此，进液管路和出液管路设置简单，而且可以同时满足两个充电连接件20的需求。
如图9所示，根据本申请实施例的车辆1000，包括上述实施例的充电装置100。其中，车辆1000还可以包括：冷却***200，冷却***200、第一冷却管路2和冷却***200连通。也就是说，冷却***200可以构成第一冷却管路2的冷却源，冷却***200可以与第一冷却管路2形成循环回路，从而可以保证第一冷却管路2内有持续流动的冷却液，进而可以有效降低充电连接件20的工作温度。
如图6所示，冷却***200可以包括：第一泵体210、第一换热器220和第一储液罐230，第一泵体210、第一换热器220、第一储液罐230和第一冷却管路2之间形成循环回路。如此设置的第一冷却管路2可以参与到冷却***200的循环中，从而可以有效降低充电连接件20的工作温度。冷却***200还包括：第一过滤器240，第一过滤器240设置在第一泵体210和第一换热器220之间，第一过滤器240可以起到过滤作用。
如图6所示，车辆1000还可以包括：第一插接检测件300和第一电控模块400，第一插接检测件300用于检测***充电连接件20内的充电枪610插接状态，第一电控模块400与第一插接检测件300电连接，而且第一电控模块400在接收到充电枪610插接完成信号后控制第一泵体210工作。车辆1000还可以包括：第一配电模块500，第一配电模块500设置在第一插接检测件300和第一电控模块400之间。由此，充电插座可以实现合理控制的目的，在充电时可以保证第一冷却管路2内流动有冷却介质。
需要说明的是，车内冷源可以直接与第二冷却管路3相连通，再使冷却液流向第一冷却管路2，或者，车内冷源可以通过车身蒙皮40内的流道与第一冷却管路2连通，再流向第二冷却管路3。
下面再结合图7描述一种充电***。
根据本申请实施例的充电***，包括：上述实施例的充电装置100和外部冷源，外部冷源可以为车外冷却***700，车外冷却***700与第一冷却管路2相连通。其中充电装置100可以为图3所示的充电装置100，这样车外冷却***700可以与外接头50的两个接口对接以实现进液和出液的循环。车外冷却***700的设置这样无需在车辆1000内部设置冷却***200，从而可以降低车辆1000的成本，而且车外冷却***700可以对应多个车辆1000，从而通用性较好。
如图7所示，车外冷却***700可以包括：第二泵体710、第二换热器720、第二储液罐730，第二泵体710、第二换热器720、第二储液罐730和第一冷却管路2串联连接。如此设置的第一冷却管路2可以参与到车外冷却***700的循环中，从而可以有效降低充电连接件20的工作温度。车外冷却***700还包括：第二过滤器740，第二过滤器740设置在第二泵体710和第二换热器720之间，第二过滤器740可以起到过滤作用。
如图7所示，车辆1000还可以包括：第二插接检测件800和第二电控模块900，第二插接检测件800用于检测***充电连接件20内的充电枪610插接状态，第二电控模块900与第二插接检测件800电连接，而且第二电控模块900在接收到充电枪610插接完成信号后控制第二泵体710工作。车辆1000还可以包括：第二配电模块，第二配电模块设置在第二插接检测件800和第二电控模块900之间。由此，充电插座可以实现合理控制的目的，在充电时可以保证第一冷却管路2内流动有冷却介质。
其中，如图7所示，充电***还可以包括：充电桩600，充电桩600包括充电枪610，车外冷却***700设置有与第一冷却管路2的外接头50对接的对接头620，对接头620设置在充电枪610上。这样在充电枪610与充电插座对接时，对接头620与外接头50即可同步完成对接，从而可以使得充电***操作简单且方便，使用安全性高。
