纯电动汽车依据整车热管理原理图，需要通过电磁阀实现多种工况的需要，现已经上市的车型中，常见有三通电磁阀，四通电磁阀。目前纯电动车为了提高续航里程，整车热管理系统设计要求工况越来越多，九通及其更多通的电磁阀就显得更重要。
如图1所示，本申请实施例公开了一种集成式多通电磁阀，包括：至少两个子电磁阀20，每个子电磁阀20包括至少两个连接管口；至少一个第一接头30，每个第一接头30包括至少两个连接头；其中，至少两个连接管口中存在至少一个用于与其他子电磁阀20连通的第一连接管口，第一接头30用于连接任意两个子电磁阀20，连接头与第一连接管口连接。
本申请实施例所述的集成式多通电磁阀，将多个子电磁阀20集成在一起，每个子电磁阀20的任意连接管口之间均可以互通，满足多种工况控制需求；轻量化设计，零件数目较少，重量轻，且使用成本低。
本申请实施例中，如图1所示，采用管路连接中常用的接头将多个子电磁阀20串联在一起形成集成的多通电磁阀。组成多通电磁阀的每个子电磁阀20均为现有工业技术中广泛应用的普通电磁方向控制阀，每个子电磁阀20至少有两个连接管口，可选的，子电磁阀20可以为二通电磁阀、三通电磁阀、四通电磁阀等。组成多通电磁阀的每个子电磁阀20可以具有相 同的连接管口数目，也可以具有不同的连接管口数目。每个子电磁阀20的连接管口分为两类，第一类连接管口为用于与其他子电磁阀20串联接通的第一连接管口，每个子电子阀中有一个或多个第一连接管口；第二类连接管口为用于接通管路的第二连接管口，第二连接管口构成了多通电磁阀的连接管口。第一接头30为管路连接中常用的接头，可选的，第一接头30为两通接头、三通接头、四通接头等。第一接头30中的连接头也可以分为两类，第一类连接头用于与第一连接管口连接，第二类连接头参与构成了多通电磁阀的连接管口。需要说明的是，当一个子电磁阀20中存在两个以上的第一连接管口时，单个第一接头30中的第一类连接头仅与其中一个第一连接管口连接；每个第一接头30中最多有一个第二类连接头。本申请实施例中的子电磁阀20的材质可以为金属材质或塑料材质，组成多通电磁阀的每个子电磁阀20可以为不同的材质。第一接头30的材质可以为金属材质或塑料材质，第一接头30的材质可以与子电磁阀20相同，如子电磁阀20与第一接头30均为金属材质；第一接头30的材质可以与子电磁阀20不同，如子电磁阀20为金属材质，第一接头30均为塑料材质。
如图1所示，集成式多通电磁阀还包括底座10，任意子电磁阀20与底座10连接。
本申请实施例中，底座10为具有连接面的板材，底座10用于集成固定子电磁阀20，子电磁阀20的阀体与底座10连接。可选的，每个子电磁阀20的阀体均与底座10连接；可选的，部分子电磁阀20的阀体与底座10连接。
至少两个连接管口还包括第二连接管口，底座10上开设有连接孔101，第二连接管口与连接孔101连接。
本申请实施例中，如图2所示，为了进一步提高零件的集成程度，便于多通电磁阀的安装使用，将多通电磁阀的连接管口集成在底座10上，子电磁阀20中的第二连接管口构成了多通电磁阀的连接管口，因此在底座10上开设连接孔101，将子电磁阀20的第二连接管口与连接孔101连接。
如图2所示，集成式多通电磁阀还包括第二接头40，第二接头40包括第一端和第二端，第一端与第二连接管口连接，第二端与连接孔101连接。
本申请实施例中，如图1和图2所示，当子电磁阀20中的第二连接管口方向平行与底座10，或与底座10之间存在一定距离时，采用第二接头40将第二连接管口与底座10上的连接孔101连接。第二接头40通常情况可采用两通接头，其材质可以与子电磁阀20相同，也可以与子电磁阀20不同。
连接孔101的数量大于或等于第二接头40的数量。
本申请实施例中，集成式多通电磁阀的连接管口包括子电磁阀20的第二连接管口和第一接头30中的第二类连接头，因此并不是所有的连接孔101均与第二接头40连接。
连接孔101的数量大于第二接头40的数量，至少一个连接孔101与连接头连接。
本申请实施例中，当第一接头30中存在第二类连接头时，即第二类连接头参与构成多通电磁阀的连接管口时，部分连接孔101可直接与连接头连接。
第一接头30的数量比子电磁阀20的数量至少少一个。
本申请实施例中，第一接头30用于将子电磁阀20串联起来，当一个子电磁阀20中存在两个以上的第一连接管口时，单个第一接头30中的第一类连接头仅与其中一个第一连接管口连接，因此第一接头30的数量要少于子电磁阀20的数量。例如，多通电磁阀由两个子电磁阀20组成，则仅需一个第一接头30即可将两个子电磁阀20连通。又如，多通电磁阀由两个以上的子电磁阀20组成，则需要一个或更多个第一接头30才能将所有的子电磁阀20连通。总的来说，集成式多通电磁阀中所需第一接头30的数量取决于子电磁阀20的数量，以及第一接头30中的连接头数目。
第一接头30为两通接头、三通接头或四通接头。
本申请实施例中，为了降低成本，同时提高零件的通用化程度，第一接头30采用目前管路连接中常用的两通接头、三通接头或四通接头。
子电磁阀20为两通电磁阀、三通电磁阀或四通电磁阀。
本申请实施例中，子电磁阀20采用目前市面上常用的两通电磁阀、三通电磁阀或四通电磁阀，根据最终的设计需求选用所需的子电磁阀20的组 合。例如，如图2所示，目标多通电磁阀为九通电磁阀，可采用两个四通子电磁阀203和一个三通子电磁阀20的组合，上述三个子电磁阀20通过一个四通的第一接头30连接起来，第一接头30中的一个连接头构成九通电磁阀的一个连接管口；还可以采用三个四通子电磁阀203的组合，上述三个子电磁阀20通过一个三通的第一接头30连接起来。同理，通过选用不同数目和不同连接管口数目的子电子阀组合，还可以实现十通电磁阀、十一通电磁阀或更多通电磁阀。需要说明的是，集成式多通电磁阀的实施方式并不仅限于上述描述，如图3所示，在一些实施方式中，底座10上还可以集成有未采用第一接头30与其他子电磁阀20连接的子电磁阀20，而是通过在底座10连接面一端实现与其他子电磁阀20的连通。例如在九通电磁阀的设计中，还可以采用一个四通子电磁阀203和两个三通子电磁阀20的组合，如图3所示，其中第一三通子电磁阀201与四通子电磁阀203通过一个三通的第一接头30连接起来，第一接头30中的一个连接头构成九通电磁阀的一个连接管口，第二三通电磁阀与底座10单独连接。当该九通电磁阀安装使用时，在与底座10匹配的阀座或管路系统中，再将上述独立的第二三通子电磁阀202与四通子电磁阀203和第一三通子电磁阀201连通。通过控制电机旋转两个三通子电磁阀及四通子电磁阀203的阀体，使各个连接管口之间的连通情况进行切换，实现整车工况需求。
子电磁阀20的种类包括直动式电磁阀、分步直动式电磁阀、先导式电磁阀中的至少一种。
本申请实施例中，组成多通电磁阀的每个子电磁阀20可以为相同种类的电磁阀，也可以为不同种类的电磁阀。为了控制的统一性与便捷性，每个子电磁阀20优选为相同种类的电磁阀。
第一端通过激光焊接工艺与第二连接管口连接。
本申请实施例中，现有技术中，如何实现电磁阀连接管口之间的可靠连接是亟待解决的问题。本申请采用激光焊接技术实现第一接头30和第二接头40与子电磁阀20的连接。激光焊接可将入热量降到最低的需要量，热影响区材料变化范围小，且因热传导所导致的变形亦最低。激光焊接不需使用电极，没有电极污染或受损的顾虑。且由于激光焊接不属于接触式 焊接制程，机具的耗损及变形皆可降至最低。激光束易于聚焦、对准及受光学仪器所导引，不会受到焊接空间的限制而无法发挥。同时，激光束可聚焦在很小的区域，可焊接小型且间隔相近的部件，可焊材质种类范围大，亦可相互接合各种异质材料。而且易于以自动化进行高速焊接，亦可以数位或电脑控制。
第二端通过热板焊接工艺与连接孔101连接。
本申请实施例中，第一接头30、第二接头40以及底座10均采用塑料材质，第一接头30和第二接头40与底座10可采用热板焊接的方式连接。
本申请实施例还公开了一种车辆热管理系统，车辆热管理系统包括如上所述的集成式多通电磁阀。
本申请实施例中，车辆热管理系统包括集成式多通电磁阀，关于集成式多通电磁阀的结构请参见上文描述集成式多通电磁阀的所有方式。本申请所述的车辆热管理系统，可根据车辆热管理系统的多种工况需求来设计满足需求多通电磁阀。通过采用集成式多通电磁阀来搭建系统构架，车辆热管理系统可以更多的功能，同时可以简化控制结构，满足更精确的控制需求；此外，采用集成式多通电磁阀能够简化管路系统，减少管路数量，从而减少管路连接与封闭用的部件数，降低成本，且方便检修。
本申请实施例还公开了一种车辆，车辆包括如上所述的车辆热管理系统。
本申请实施例中，对于纯电动汽车而言，续航里程一直是限制其发展的主要因素。本申请实施例所述的车辆，热管理系统中采用了集成式多通电磁阀，可通过设计相应的控制逻辑来实现多种节能工况，使动力电池中的能量能更多的应用于车辆续航里程。
以上所述仅为本申请的较佳实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
