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的散热装置100。
如图1-图16所示，根据本申请实施例的车辆的散热装置100可以包括：散热主体30、充电连接件20的散热器10和充电连接件20，散热主体30包括：板体31，散热器10固定在板体31上，散热器10设置有容纳孔12，充电连接件20容纳在容纳孔12上。需要说明的是，容纳孔12可以仅起到容纳作用，当然，其可以通过设置起到安装固定作用，例如，在内周设置一些安装结构。
散热器10可以起到安装充电连接件20的作用，散热器10还可以起到为充电连接件20散热的作用，而且其可以将充电连接件20产生的热量传递给板体31和外界环境，这样可以进一步地降低充电连接件20的温度。
充电连接件20可以为充电插座，充电连接件20可以包括接线端子21，如此设置的散热装置100可以有效降低接线端子21的温度，从而可以避免出现接线端子21过热的问题，进而可以提升散热装置100的工作可靠性，可以保证车辆的充电安全性。接线端子21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21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。
下面结合附图详细描述一下根据本申请实施例的充电连接件20的散热器10。
如图5-图8所示，根据本申请第一实施例的散热器10可以包括：主体1，当然，散热器10还可以包括其他部件，例如，多个第一散热片4和送风件7，主体1内形成有冷却室11，冷却室11内可以充满有冷却介质，冷却介质可以为冷却水，也可以为其他冷却液，当然，还可以为冷却气体。而且主体1的内周限定出容纳孔12，容纳孔12用于容纳充电连接件20。也就是说，充电连接件20的一部分可以容纳在主体1上，主体1上设置有冷却室11，这样冷却室11内的冷却介质可以有效冷却充电连接件20，从而可以有效带走充电连接件20的热量，可以更好地降低充电连接件20的工作温度，可以避免充电连接件20的接线端子过热，进而可以保证车辆的充电安全性。
如图5-图8所示，多个第一散热片4分布在主体1的外表面上，多个第一散热片4可以有效增加主体1的散热面积，从而可以进一步地有利于充电连接件20的散热，可以有利于降低接线端子的温度。具体的，多个第一散热片4分布在主体1的外周壁上。
如图5所示，送风件7安装在主体1上。可以理解的是，送风件7可以向主体1和充电 连接件20送风，风可以在经过主体1时有效带走主体1的热量，从而可以加快充电连接件20的散热，可以提升散热器10的散热性能。
根据本申请实施例的散热器10，通过设置冷却室11、第一散热片4和送风件7，可以采用液冷、自然冷和风冷的组合来对充电连接件20进行冷却，从而可以有效控制充电连接件20的工作温度，可以有效避免充电连接件20的接线端子过热，进而可以保证车辆的充电安全性。另外，如此设置的散热器10结构简单，成本低。
根据本申请的一个实施例，如图6和图8所示，冷却室11设置在主体1的底部，而且冷却室11与多个第一散热片4在主体1的径向上间隔开设置。也就是说，冷却室11与多个第一散热片4在主体1上不会发生干涉，由此，如此设置的冷却室11一方面可以有效冷却充电连接件20，另一方面可以有利于主体1的合理设置，可以为第一散热片4留有足够的设计空间，从而可以便于两者结合以更好地进行散热。
根据本申请的一个实施例，送风件7安装在冷却室11的下方，冷却室11的进口和出口设置在主体1的两侧。如此设置的送风件7还可以带走主体1的热量，而且还可以至少一定程度上降低冷却室11的温度，从而可以充电连接件20的工作温度。
根据本申请的一个实施例，如图6所示，主体1上设置有通风孔13，送风件7产生的风通过通风孔13流向多个第一散热片4。由此，送风件7处的风可以通过通风孔13向多个第一散热片4送风，这样风可以有效带走第一散热片4上的热量，从而可以有利于第一散热片4更好地散热，进而可以有效降低充电连接件20的工作温度，可以保证车辆的充电安全性。具体地，通风孔13设置主体1的外周壁上且贯穿主体1的外周壁，与多个第一散热片4形成的风道连通。
如图5-图7所示，多个第一散热片4沿主体1的周向延伸，而且多个第一散热片4在主体1的轴向间隔开设置。由此，可以有利于送风件7在两个第一散热片4之间走风，从而可以保证风与第一散热片4的接触面积，可以保证第一散热片4的有效散热。
根据本申请的一个实施例，冷却室11具有朝向送风件7送风方向的冷风侧壁，冷风侧壁与送风件7间隔开，通风孔13位于冷风侧壁与送风件7之间。由此，送风件7送出的风可以直接吹响冷却室11，从而可以有效降低冷却室11内的冷却水的温度，而且，风可以通过通风孔13向外流出，从而可以有利于风的循环。
如图5、图7所示，主体1呈倒U形且包括分别设置两侧的第一侧壁101和第二侧壁102，第一侧壁101与第二侧壁102贴合设置，其中第一侧壁101与第二侧壁102之间设置有连接部103，连接部103与第一侧壁101底端的距离和连接部103与第二侧壁102底端的距离相同，连接部103可以将第一侧壁101和第二侧壁102连接，且连接部103与第一侧壁101的至少部分和第二侧壁102形的至少部分围成了容纳孔12，进一步地，连接部103包括第 一连接部103a和第二连接部103b，其中第一连接部103a可以与第一侧壁101一体成型，第二连接部103b可以与第二侧壁102一体成型，在第一侧壁101与第二侧壁102配合后，第一侧壁101、第二侧壁102、第二连接部103b和第一连接部103a围成了容纳孔12，这样容纳孔12设置方便，主体1结构简单。
如图5和图7所示，主体1的外表面为倒置整U形，在主体1的外表面上，第一散热片4可以沿主体1的外周延伸，以围绕主体1的外表面的周向设置。多个第一散热片4中的一部分从主体1的第一侧壁101的底端一直延伸至主体1的第二侧壁102的底端，从而该第一散热片4的形状与主体1的形状相同，二者均为倒置整U形；多个第一散热片4中的另一部分的始端或/和终端可以不与第一侧壁101的底端和第二侧壁102的底端平齐，即该第一散热片4的形状与所述主体1的形状不同，该第一散热片4为倒置的半U形，从而可以避让冷却室11上的进口和出口。
多个第一散热片4可以充分利用主体1的外表面面积，而且可以为冷却室11的进口和出口留有足够的空间，从而可以使得主体1结构布置合理，散热效果好。
根据本申请的一个实施例，如图7所示，多个第一散热片4在主体1上延伸至两侧边(第一侧壁101或第二侧壁102)的底端且还弯折延伸至底端的底面上。也就是说，多个第一散热片4还可以在底端的底面上延伸，这样可以进一步地增加散热面积，而且可以降低制造难度。
如图5所示，送风件7设置在两侧边的相对底端处。这样送风件7位置设置合理，送风件7可以合理利用主体1的空间，而且能够向冷却室11合理送风，从而可以有效降低充电连接件20的温度。
如图6和图7所示，两侧边的底端上设置有卡接槽14，送风件7的侧边卡接在卡接槽14内。卡接槽14的设置可以至少一定程度上方便送风件7的安装，可以降低送风件7的安装难度。其中，送风件7为可以为风扇。风扇结构简单，成本低。
根据本申请的一个实施例，如图7所示，卡接槽14呈L形，而且卡接槽14包括：长槽14a和短槽14b，长槽14a在主体1的轴向延伸，而且短槽14b在侧边底端的侧向延伸。长槽14a和短槽14b的设置可以便于送风件7的边缘在两个方向安装固定，从而可以进一步地提升送风件7的安装可靠性，而且可以使得送风件7较合理地位于冷却室11的下方。
长槽14a的长度小于侧边的轴向长度，短槽14b的长度小于侧边的厚度。由此，可以保证主体1的两侧的结构强度，可以降低长槽14a和短槽14b的设置对于主体1的影响，还可以提高送风件7的安装可靠性。
如图9-图16所示，根据本申请的第二实施例的散热器10可以包括主体1和多个第一散热片4，主体1内形成有冷却室11，而且主体1的内周限定出容纳孔3，容纳孔3用于容 纳充电连接件20。也就是说，充电连接件20可以安装在容纳孔3内，容纳孔3的设置一方面可以保证充电连接件20的安装可靠性，另一方面可以保证主体1和充电连接件20充分接触，从而可以有利于冷却室11与充电连接件20充分换热。
充电连接件20内设置有多个接线端子21，例如，接线端子21为两个，接线端子21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21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。
如此，冷却室11可以有效降低接线端子21的温度，可以避免接线端子21出现过热的问题，从而可以保证车辆的充电安全性。冷却室内可以充满有冷却介质，冷却介质可以为冷却液。
如图9-图16所示，多个第一散热片4分布在主体1的外周上。第一散热片4可以与冷却室11共同作用，从而可以更好地带走充电连接件20的温度，可以有效降低接线端子21的温度。
当然，散热器10还可以包括其他部件，例如，如图10-图12所示，散热器10还可以包括：多个端子护套5，多个端子护套5固定在主体1上，而且端子护套5位于容纳孔3内，这样可以便于端子护套5与接线端子21对应。端子护套5的数量可以与多个接线端子21的数量对应，端子护套5可以套设在对应的接线端子21上。
接线端子21也可以通过端子护套5向主体1传递热量，从而可以使得冷却室11和第一散热片4更好地降低接线端子21的温度，而且端子护套5至少一定程度上可以保护接线端子21。
根据本申请实施例的散热器10，通过设置冷却室11和第一散热片4，可以有效降低接线端子21的温度，可以避免出现接线端子21过热的问题，可以保证车辆的充电安全性。
如图11所示，主体1可以包括后壁16，端子护套5从后壁16沿轴向向前延伸，后壁16上形成有端子孔17。当给车辆充电时，接线端子21可以插入到端子孔17内，从而可以便于接线端子21与端子护套5配合。
结合图13-图15及图1所示，主体1的底部形成有进液口1a和出液口1b，进液口1a和出液口1b间隔开设置。由此，进液口1a和出液口1b设置合理，进液和出液方便，可以使得主体1结构简单，冷却室11布置合理。
出液口1b设置有压力阀(图未示出)，而且在冷却室11内压力达到预定值压力阀打开。由此，通过设置压力阀，可以控制冷却室11内的冷却介质的量，可以保证在充电连接件20与充电桩600的充电枪610对接时冷却室11内有足够的冷却介质，从而可以保证主体1降低接线端子21温度的作用。
当然，进液口1a和出液口1b还可以有其他布置形式，例如，主体1上形成有进液口1a和出液口1b，进液口1a位于出液口1b的正上方，或者进液口1a位于出液口1b的正下方。如此设置的进液口1a和出液口1b可以保证冷却介质有效地在冷却室11进行循环流动，从而可以使得冷却室11更好地降低充电连接件20的温度，可以避免接线端子21出现过热的问题。
根据本申请的一个实施例，进液口1a位于主体1的最下端，出液口1b位于主体1的最上端。由此，冷却介质可以在充满冷却室11之后才会从出液口1b流出，从而可以更好地保证冷却室11内具有足够的冷却介质，进而可以保证散热器10降低接线端子21温度的效果。
如图16所示，进液口1a和出液口1b之间可以设置有隔板6，隔板6用来保证冷却介质在冷却室11内的循环，从而可以使得冷却介质有效带走充电连接件20的热量。
如图13所示，散热器还可以包括：多个第一散热片4，多个第一散热片4分布在主体1的外表面上，而且，多个第一散热片4沿主体1的轴向延伸，并且多个第一散热片4在主体1的周向上分布。这样多个第一散热片4可以均匀分布在主体1的外周上，从而可以更好地带走接线端子21的热量。
如图12所示，端子护套5与主体1可以为一体成型件。一体成型的端子护套5和主体1结构简单，易于制造，成本低。
根据本申请的一个实施例，端子护套5内形成有冷却腔，冷却腔与冷却室11连通，而且冷却腔位于冷却室11的进液口1a和出液口1b之间。也就是说，端子护套5内的冷却腔能够参与冷却室11内的冷却介质的循环，从而可以直接且有效地降低接线端子21的温度，进而可以保证车辆的充电安全性。
主体1上形成有多个固定孔，固定孔可以供固定件(如螺栓、销钉等)穿过，这样散热器10可以与充电连接件20相固定，从而可以更好地保证充电连接件20的固定可靠性。具体地，多个固定孔为四个，而且四个固定孔之间的连线呈四边形。如此布置的四个固定孔可以使得充电连接件20与散热器10固定位置合理，固定位置各处受力均匀，从而可以更好地保证充电连接件20和散热器10之间的固定可靠性。
根据本申请的一个实施例，主体1和端子护套5为绝缘材料制成。绝缘材料不导电，可以防止充电过程中向外漏电，进而可以保证充电的安全性。
需要说明的是，上述两个实施例仅是示意性说明，两者之间非冲突的部件可以相互结合，例如，第一实施例的散热器10中的送风件7也可以结合到第二实施例的散热器10中，又如，第二实施例的散热器10中的端子护套5也可以结合到第一实施例的散热器10中，再如，第二实施例的散热器10中的进液口1a和出液口1b的设置形式也可以结合到第一实施 例的散热器10的冷却室11中。
下面再结合附图进行散热主体30的描述。
如图2、图8和图12所示，散热主体30包括：冷却流道，冷却流道设置在板体31上，具体地，散热主体30包括：多个第二散热片32，多个第二散热片32设置在板体31上，每个第二散热片32内形成有冷却流道，或者说，第二散热片32设置在冷却流道上。冷却室11与第二散热片32的冷却流道连通。第二散热片32的设置可以有效加快散热器10的散热效率，这样可以进一步地有利于充电连接件20的散热。而且如此设置的第二散热片32可以满足冷却室11的进液和出液需求，可以保证冷却室11的工作可靠性。
根据本申请实施例的车辆的散热装置100，通过合理设置散热器10和散热主体30，可以有利于充电连接件20的散热，可以保证充电连接件20的工作可靠性，可以保证车辆的充电安全性。
冷却流道围绕冷却室11设置。这样冷却流道冷却散热器10和充电连接件20的效果较好，而且冷却流道和冷却室11之间冷却液流动效果好。
根据本申请的一个实施例，如图2-图4所示，板体31上可以形成有共用进口31a和共用出口31b，多个第二散热片32的冷却流道共用一个共用进口31a和一个共用出口31b。也就是说，板体31上设置一个共用进口31a和一个共用出口31b即可，这样可以降低板体31的复杂程度，而且可以保证每个第二散热片32的进液出液顺畅性。
根据本申请的一个实施例，共用进口31a位于共用出口31b的正上方。由此，可以便于冷却介质在重力作用下从上向下流动，从而可以有利于冷却介质在第二散热片32内的流动，可以提高散热装置100的整体运行可靠性。或者，共用进口31a位于共用出口31b的正下方，这样可以在冷却流道内充满冷却液之后，冷却液才会从冷却流道内流出，从而可以提高散热器10的冷却效果。
冷却室11的两端设置有进口和出口，进口至少与一个第二散热片32的冷却流道相连，而且出口至少与另一个第二散热片32的冷却流道相连。换言之，冷却室11可以连接在两个第二散热片32之间，这样冷却室11保证其自身的进液和出液，而且可以有效与主体1和充电连接件20进行换热。
根据本申请实施例的车辆，包括：上述实施例的散热装置100和冷却系统200，冷却流道和冷却室11分别与冷却系统200连通，连通方式可以为串联或者并联。也就是说，冷却室11和冷却流道串联在冷却系统200，当充电连接件20为动力电池充电时，冷却系统200开始工作，冷却介质流经冷却流道和冷却室11，从而可以不断带走接线端子的热量，可以避免接线端子过热，可以保证车辆的充电安全性。
根据本申请的一个实施例，如图1所示，冷却系统200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、散热主体30的冷却流道和冷却室11之间形成循环回路。由此，泵体210可以在充电连接件20和充电桩600上的充电枪610对接时工作，从而将冷却介质泵入冷却流道和冷却室11内，以使得冷却室11内的冷却介质不断带走接线端子的热量，需要说明的是，接线端子发热是通过充电连接件20的外壳传递给散热器10，然后在由送风件7和冷却介质间接带走端子的热量。冷却系统200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。
根据本申请的一个实施例，如图1图2、和17所示，车辆还可以包括：插接检测件300和电控模块400，插接检测件300用于检测插入充电连接件20内的充电枪610插接状态，电控模块400与插接检测件300电连接且在接收到充电枪610插接完成信号后控制泵体210和送风件7工作。其中，如图1所示，充电连接件20还可以包括：配电模块500，配电模块500可以向电控模块400配电，而且电控模块400控制泵体210的工作状态。由此，充电连接件20可以实现合理控制的目的，在充电时可以保证冷却管路内流动有冷却介质。
电控模块400还可以控制送风件7的工作状态。需要说明的是，电控模块400可以合理控制冷却系统200和送风件7的工作状态，例如，在充电连接件20处的温度达到第一预定温度时，冷却系统200的泵体210工作，在充电连接件20处的温度达到第二预定温度时，送风件7工作。其中送风件7可以分别多个风力等级，随着温度的升高，不断升高等级。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
