实施例一
图1为本申请实施例提供的混合动力全地形车的车辆冷却系统的结构示意图。请参照附图1，本实施例一种混合动力全地形车的包括：车架9(参见图4)、前轮、后轮、动力系统100、电机散热器30和水泵50。
其中，前轮位于车架9的前侧，后轮位于车架9的后侧。动力系统可以固定在车架9上，动力系统包括电机和发动机40；发动机40用于驱动电机产生电能或者用于为前轮或后轮输出动力，电机用于在发动机40的驱动下产生电能或者用于为前轮或后轮输出动力。
电机内部具有电机冷却通道；电机散热器30固定在车架9上，电机散热器30包括电机散热器进液口31和电机散热器出液口32，电机散热器进液口31、电机冷却通道与电机散热器出液口32依次连通以形成电机冷却系统。
水泵50连接于电机冷却系统中，且水泵50离地面的高度小于或等于电机冷却通道的两个端部离地面的高度；和/或，水泵50离地面的高度小于或等于电机散热器进液口31和电机散热器出液口32离地面的高度。由此，使得水泵50位于电机冷却系统的最低位置。由于水是往下流，水泵50设置在最低位置，使得水泵50能够快速地将电机散热器30处的冷却液泵向电机冷却系统的各处，从而最大程度上提高冷却效率。
本实施例的混合动力全地形车该混合动力全地形车采用燃料(汽油、柴油等)和电能的混合动力驱动。更具体的，本实施例的车辆可以为增程式车辆。
本申请实施例所提供的混合动力全地形车，电机具有电机冷却通道，电机散热器进液口、电机冷却通道、与电机散热器出液口依次连通形成电机冷却系统，水泵在电机冷却系统中的位置处于电机冷却系统的最低位置，使得水泵能够快速地将电机散热器的冷却液泵向电机冷却系统，使得整个电机冷却系统的循环效率较高，有效提高了电机散热效率，使得电机能够得到快速散热，进而有效提高电机的使用寿命，保证全地形车的行车安全。
具体的，电机可以包括第一电机10和第二电机20，本实施例的第二电机20可以与发动机40连接，并在发动机40的驱动下产生电能，而第二电机20可以与第一电机10电连接，使得第一电机10通过第二电机20产生的电能为前轮或后轮输出动力，具体的，第二电机20为第一电机10提供电能，第一电机10用于与车辆的车桥(图中未示出)驱动连接，进而使得第一电机10的动力传输给车轮。由于发动机40可以给第二电机20发电，而第二电机20可以为第一电机10提供电能，使得整车续航里程增加。
第一电机10内部可以具有第一电机冷却通道，第二电机20内部可以具有第二电机冷 却通道。其中，第一电机冷却通道可以为设于第一电机10内的管路，还可以为第一电机10内部壁面形成的腔体通道，第二电机冷却通道可以为设于第二电机20内的管路，还可以为第二电机20内部壁面所形成的腔体通道，本实施例不做特别限定。
具体的，水泵50离地面的高度小于或等于第一电机冷却通道的两个端部离地面的高度，和/或，水泵50离地面的高度小于或等于第二电机冷却通道的两个端部离地面的高度。
电机散热器进液口31、第一电机冷却通道、第二电机冷却通道与电机散热器出液口32连通以形成电机冷却系统。冷却液途径电机散热器30、第一电机冷却通道、第二电机冷却通道以将第一电机10和第二电机20进行冷却散热。
其中，电机散热器30还可以连接有加液箱30a，加液箱30a设置在车架9上。具体的，加液箱30a的一端可以通过通气管30b连通至电机散热器30，加液箱30a的另一端可以连接有加液管30c，加液管30c可以设于水泵50与电机散热器出液口32之间。
具体地，加液箱30a主要用于为循环冷却通道补充循环液，循环液在循环冷却通道中循环流动时并不会流入加液箱30a中。由于加液管30c的另一端连通在水泵50和电机散热器出液口32之间，因此，从加液箱6流入循环冷却通道的循环液不需要经过电机散热器30，便可以在水泵50的驱动下流向电机冷却系统。
在其它实施方式中，也可以是加液管30c的一端连通加液箱30a，另一端连通在控制器冷却通道的第一端和电机散热器出液口32之间。
由于冷却液在循环冷却系统中循环流动时，不可避免地会产生一些气泡，因此，通过设置通气管30b，可以有效地排出循环冷却系统中的气泡，以保证冷却液能够具备良好的吸热功能。在本实施例中，通气管30b与加液箱30a连通的一端可以与加液箱30a的加注口连通，以防止加液箱30a中的冷却液的液面高度高于通气管30b与加液箱30a连通的一端的设置高度，而使循环液流入通气管30b中。当然，在其它实施方式中，也可以不设置加液箱30a和通气管30b。
电机散热器出液口32与第一电机冷却通道的第一端连通，电机散热器进液口31与第二电机冷却通道的第一端连通，第一电机冷却通道的第二端与第二电机冷却通道的第二端连通。需要说明的是，此处所描述的连通，是包括直接连通，也可以包括间接连接。由于电机散热器出液口32是与第一电机冷却通道的第一端连通，电机散热器进液口31是与第二电机冷却通道的第一端连通的，因此，当冷却液在循环冷却通道中循环流动时，从散热器出液口32流出的冷却液先经过第一电机10，然后经过第二电机20，最后再从电机散热器进液口31流入电机散热器30中进行散热，由此，可以将第一电机10和第二电机20运行而产生大量热量带到电机散热器30处，以通过电机散热器30将热量散发到外部环境中，从而可以对第一电机10和第二电机20进行有效地散热，进而可以提高电机的使用寿命， 并保证混合动力全地形车的行车安全。
另外，由于第二电机20用于发电，是将机械能转换为电能，而第一电机10作为驱动电机，用于发电的第二电机20所产生的热量大于第一电机10所产生的热量，因此，在本实施例的电机冷却系统中，冷却液先吸收温度相对较低的第一电机10所产生的热量，再吸收温度相对较高的第二电机20所产生的热量，使得热传递效率最高，冷却效果最好。
进一步的，如图1所示，本实施例的车辆冷却系统还包括控制器60，控制器60连接在电机冷却系统中，控制器60内具有控制器冷却通道，水泵50离地面的高度小于或等于控制器冷却通道的两个端部离地面的高度。控制器冷却通道可以串联于电机散热器出液口32与第一电机冷却通道之间；其中，电机散热器出液口32与控制器冷却通道的第一端连通，控制器冷却通道的第二端与第一电机冷却通道的第一端连通。
在本实施例中，控制器60可以用于与第一电机10和第二电机20配合，控制器60可以具有多种控制功能，比如，控制器60可以具有第一控制端和第二控制端，第一控制端与第一电机10连接，第二控制端与第二电机20连接，以使第一电机20产生的电能经过控制器60的调制后输送给第一电机10。另外，控制器60还可以与整车的其他电控部件电连接，以实现整车控制。
在一些实施例中，电机散热器可以位于车架9的前侧；发动机40固定在车架9上且位于电机散热器的后方，第二电机20与发动机连接且位于发动机的前方，第一电机10位于发动机的后方，控制器60可以位于发动机40的一侧。
由于控制器60在工作状态下也会产生一定的热量，因此，在控制器60内部设置控制器冷却通道，将控制器冷却通道接入电机冷却系统，使得电机冷却系统的冷却水经过控制器60以对控制器60散热，提高控制器60的使用寿命，避免车辆出现因控制器60因高温损坏而突然失灵导致失控的情况发生。
进一步地，由于控制器60所产生的热量要小于第一电机10和第二电机20产生的热量，因此，本实施例的控制器60设于在电机散热器30和第一电机10之间，在电机散热器30处释放了热量的冷却液从电机散热器30流出之后，依次经过控制器60、第一电机10和第二电机20，然后再回到电机散热器30，其中，控制器60工作所产生的热量＜第一电机10工作所产生的热量＜第二电机20工作所产生的热量，由此使得控制器60、第一电机10和第二电机20都能够合理有效地进行散热，冷却液的冷却效果最好。
在上述实施例的基础上，进一步的，如图1所示，水泵50可以设于控制器冷却通道的第二端与第一电机冷却通道的第一端之间。水泵50的设置可以加快冷却液的循环效率，保证散热速度。将水泵50设置在第一电机10与第二电机20之前，由于第一电机10和第二电机20工作时的热量较多，而水泵50设置位置距离第一电机10和第二电机20较近，可 以使得冷却液快速地泵向温度较高的第一电机10和第二电机20，使得第一电机10和第二电机20快速散热。
当然，在其他实施例中，如图2所示，水泵50可以设于电机散热器出液口32与控制器冷却通道的第一端之间，经过电机散热器30散热之后的循环液可以在水泵50的驱动下尽快地流向控制器60、第一电机10和第二电机20，以提高控制器60、第一电机10和第二电机20的散热速度。或者，水泵50设于第二电机冷却通道的第二端与第一电机冷却通道的第二端之间；或者，水泵50设于电机散热器进液口31与第二电机冷却通道的第一端之间。水泵50可以设置在电机冷却系统中的任意位置，只要是能够将电机散热器30处的冷却液快速泵向电机冷却系统即可，本实施例不做特别限定。
进一步的，如图1所示，本实施例所提供的混合动力全地形车还包括：发动机冷却通道，水泵50离地面的高度小于或等于发动机冷却通道的两个端部离地面的高度。
发动机冷却通道包括发动机散热器70，发动机散热器70包括发动机散热器进液口71和发动机散热器出液口72。发动机40内部具有发动机冷却通道，发动机散热器出液口72、发动机冷却通道的第一端、发动机冷却通道的第二端与发动机散热器进液口71依次连通以形成发动机冷却系统。
由于发动机40在工作过程中也会产生大量热量，并且热量较多，因此通过独立设置用于对发动机40散热的发动机冷却系统，使得发动机40的冷却与电机的冷却相互独立，互不影响，从而有效地提升了发动机40及电机的散热效果，使得车辆动力充足。
进一步的，如图1所示，电机冷却系统与发动机冷却系统沿车辆的宽度方向并排设置。所谓电机冷却系统与发动机冷却系统并排设置是指整体上呈并排布置，而并非每个零部件均沿车辆的宽度方向并排设置，在本实施例中，至少电机散热器和发动机散热器70可以在车辆的宽度方向并排设置，结构紧凑，布局合理。更具体的，发动机散热器70和电机散热器沿混动全地形车的纵向中心面对称布置，使得整车质量分布尽量均匀，在一定程度上提高整车的平衡性，提高行驶安全。
进一步的，发动机冷却通道可以通过发动机进水管与发动机散热器出液口72连通，发动机40上设有机油冷却器(图中未示出)，机油冷却器可以与发动机进水管连通。具体的，机油冷却器可以通过机油冷却管73与发动机进水管连通，从发动机散热器出液口72出来的冷却液一部分直接进入发动机进水管，另一部分进入机油冷却器，由此可以用于对发动机40内部的机油进行冷却，进一步帮助发动机40散热。
需要说明的是，在本实施例中，优选的，机油冷却管73可以为胶管，以便于组装连接。
在本实施例中，电机冷却系统中的管道可以包括至少一个刚性管道和至少一个柔性管道。同样的，发动机冷却系统中的管道可以包括至少一个刚性管道和至少一个柔性管道。 用于连接各个部件之间的管道可以包括至少一个刚性管道和至少一个柔性管道，刚性管道有利于限定管路的延伸路径，而柔性管道可以便于管道的安装，因此，可以在部件的连接口的位置处连接柔性管道，而在其他位置处连接刚性管道，特别的，当两个部件距离较近时，两个部件之间的连接管道可以为柔性管道，以便于安装连接，而当两个部件距离较远时，两个部件之间的连接管道可以为刚性管道，或者为刚性管道与柔性管道组合的管道，以使得距离较远的两个部件之间的管路能按照预定路径延伸，而不易混乱。需要说明的是，上述描述的“部件”为以下部件中的一种或多种：电机散热器30、第一电机10、第二电机20、水泵50、控制器60、发动机散热器70、发动机40。
需要说明的是，本实施例中所提供的刚性管道可以为铝管，铝制材料的散热较好，通过铝管可以带走冷却液的一部分热量，进一步提高散热效果。
在本申请一个较佳实施例中，电机散热器出液口32连接第一胶管a、第一胶管a连接第一铝管b，第一铝管b通过第二胶管c与控制器冷却通道的第一端连通，控制器冷却通道的第二端通过第三胶管d与水泵50连通，水泵50再通过第四胶管e与第一电机冷却通道的第一端连通，而第一电机冷却通道的第二端通过第二铝管f与第二电机冷却通道的第二端连通，第二电机冷却通道的第一端连通第五胶管g，第五胶管g连通第三铝管h，第三铝管h连通第六胶管i，第六胶管i连通至电机散热器进液口31。
发动机散热器出液口72连接第七胶管j，第七胶管j连通第四铝管k，第四铝管k连通第八胶管l，第八胶管l连通发动机第一端，发动机的第二端连通第九胶管m，第九胶管m连通第五铝管n，第五铝管n连通第十胶管o，第十胶管o连通至发动机散热器进液口71。
需要说明的是，第八胶管l为上述的供机油冷却管73连通的发动机进水管。
实施例二本申请实施例还提供了一种混合动力全地形车，请参阅图2至图4，该混合动力全地形车包括：车架9、发动机40(参见图1)、第一电机10、车桥(图未示出)、第二电机20、电机散热器30。发动机40设置在车架9上。第二电机20与发动机40驱动连接，第二电机20内部设置有第二电机冷却通道。车桥设置在车架9上。第一电机10与车桥驱动连接，第一电机10内部设置有第一电机冷却通道。电机散热器30设置在车架9上，电机散热器30上设置有电机散热器进液口31和电机散热器出液口32，其中电机散热器进液口31与第二电机冷却通道的第一端连通，电机散热器出液口32与第一电机冷却通道的第一端连通，第一电机冷却通道的第二端与第二电机冷却通道的第二端连通。
在本实施例中，电机散热器30设置在车架的前端，在一些实施例中，混合动力全地形车还包括两个前大灯80，两个前大灯80分别设置在电机散热器30的两侧，也就是说，电机散热器30是设置在混合动力全地形车的驾驶舱的正前方，由此，可以便于电机散热器30进行散热。在其它实施方式中，电机散热器30也可以设置在车架9的后端或者侧面等 位置，只要保证电机散热器30能够进行有效散热即可。
在本实施例中，电机散热器进液口31和电机散热器出液口32分别设置在电机散热器30相对的两个侧面上，第一电机冷却通道、电机散热器进液口31、电机散热器出液口32和第二电机冷却通道之间相互连通，以在混合动力全地形车中形成了一个循环冷却通道，由于电机散热器进液口31是与第二电机冷却通道的第一端连通，电机散热器出液口32是与第一电机冷却通道的第一端连通的，所以，当循环液在循环冷却通道中循环流动时，从电机散热器出液口32流出的循环液先经过第一电机10，然后经过第二电机20，最后再从电机散热器进液口31流入电机散热器30中进行散热，由此，可以将第二电机20和第一电机10产生的热量带到电机散热器30处，以通过电机散热器30将热量散发到外部环境中，从而可以对第二电机20和第一电机10进行有效地散热，进而可以提高电机的使用寿命，并保证混合动力全地形车的行车安全。
另外，由于用于发电的第二电机20所产生的热量大于第一电机10所产生的热量，所以，在本实施例的循环冷却通道中，循环液先吸收温度相对较低的第一电机10所产生的热量，再吸收温度相对较高的第二电机20所产生的热量，由此，可以保证第一电机10和第二电机20都能进行有效地散热。
在一些实施例中，如图4所示，混合动力全地形车还包括另一散热器，该另一散热器与电机散热器30固定在一起，并且电机散热器30沿前后方向设置在该另一散热器前侧。例如，该另一散热器可以是发动机散热器70。
实施例二的其他结构与实施例一的结构基本相同，因此在此不再赘述。
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。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
