参见图1，流体控制组件100可以应用于热管理系统，其中热管理系统可以为车辆热管理系统，具体如新能源车辆热管理系统。流体控制组件100包括流体管理元件和通道元件4，其中流体管理元件可以包括阀元件1、热交换元件2、贮液元件3的至少其中之一，在本实施例中，流体管理元件包括阀元件1、热交换元件2、贮液元件3，阀元件1的数量可以为多个，阀元件1与通道元件4连接，通道元件4具有通道，通道的数量可以为多个，阀元件1能够实现通道中的两个或多个的连通或不连通，并在连通时能够实现通道之间的直通连通和/或节流连通；热交换元件2与通道元件4连接，在本实施例中，热交换元件2包括若干层叠的板片，热交换元件2具有不连通的第一流道和第二流道，第一流道内的工作流体(如制冷剂)和第二流道内的工作流体(如冷却液)可以在热交换元件3内进行换热，其中热交换元件2的第一流道与通道中的两个连通；贮液元件3与通道元件4连接，贮液元件3具有至少部分贮液腔，这是由于贮液腔还有可能由贮液元件3和其他部分共同形成，贮液腔与通道中的两个或多个连通，贮液元件3主要用于进行工作流体气液两相分离，避免工作流体(如制冷剂)中的气相流体流至后续通道回路。定义连接包括固定连接或限位连接或可拆卸连接或密封连接等方式；定义直通连通为不改变或者趋于不改变(如压损范围＜1％)工作流体流过阀元件前后的压力，定义节流连通为工作流体流过阀元件1前的压力大于流过阀元件1后的压力。
参见图2至图4，为实现流体控制组件的轻量化，通道元件4包括流道板41和第一覆合板42，在本实施例中，流道板41具有形成通道的槽腔和孔，槽腔和孔的数量可以为多个，其中孔用于形成为不同单个连通通道之间的连通孔道，孔贯穿流道板41设置，而形成通道的槽腔则不贯穿流道板41，形成通道的槽腔和孔具体可以通过冷挤压工艺一体形成。流道板41与第一覆合板42贴合设置，流道板41与第一覆合板42连接，在本实施例中流道板41与第一覆合板42通过焊接密封固定，流道板41与第一覆合板 42配合形成通道元件4的通道，这样相比与通过阀块整体机加工形成通道，有利于使通道部分元件轻量化。具体地，流道板41包括第一壁411，沿垂直于第一壁411的方向，流道板41形成有自第一壁411向内远离第一壁411的槽腔和孔，相应地，第一覆合板42包括第二壁421，在本实施例中第二壁421为平面，流道板41与第一覆合板42在配合时，第一壁411与第二壁421贴合设置，第一壁411和第二壁421通过焊接密封固定，从而形成通道元件4的通道。当然孔还可以形成于第一覆合板42上，即沿垂直于第二壁421的方向，孔贯穿第一覆合板42设置，此时流道板41仅具有形成通道的槽腔，第一壁411与第二壁421贴合并通过焊接密封固定，流道板41与第一覆合板42配合形成通道元件4的通道。

参见图1、图3以及图6，在本实施例中，热交换元件2与通道元件4通过螺钉连接固定，具体地，热交换元件2包括底板21，底板21上设置有与通道元件4螺钉连接的通孔，热交换元件2通过底板21实现与通道元件4的螺钉连接固定。热交换元件2的第一流道连通第八通道407和第二通道408，具体地，孔还包括第五孔455和第六孔456，其中第五孔455与第八通道407连通，第六孔456与第二通道408连通，热交换元件2的第一流道连通第五孔455和第六孔456。参见图1、图11以及图12，流体 控制组件100还包括多通阀元件5，多通阀元件5包括多通阀51和连接件52，在本实施例中，多通阀51为三通切换阀，多通阀51具有进口511、第一出口512、第二出口513，通过旋转多通阀51的阀芯，能够实现进口511与第一出口512连通或者进口511与第二出口513连通，在本实施例中，进口511、第一出口512、第二出口513的朝向相同，且进口511位于第一出口512和第二出口513之间，这样方便多通阀51与连接件52的装配。相应地，连接件52包括进口接头521和出口接头522，进口接头521和出口接头522用于与热管理系统中的其他如电池冷却模块进行对接，对电池组件进行降温冷却。进口接头521具有进口接头流道5211，出口接头522具有出口接头流道5221，连接件52还具有用于与热交换元件2的第二流道连通的第三流道523和第四流道524，其中第三流道523与出口接头流道5221连通。多通阀51与连接件52连接，具体地在本实施例中多通阀51与连接件52通过螺钉固定连接，多通阀51与连接件52装配连接后，进口接头流道5211与进口511连通，出口接头流道5221与第一出口512连通，第四流道524与第二出口513连通，这样通过切换多通阀51的阀芯，进口接头流道5211能够与出口接头流道5221连通或者进口接头流道5211能够与第四流道524连通。多通阀元件5与热交换元件2连接，在本实施例中，多通阀元件5的连接件52与热交换元件2的底板21通过螺钉连接固定，并使热交换元件2的第二流道连通第三流道523和第四流道524。
参见图1、图6、图9以及图11，为保证流体控制组件100在应用于热管理系统时保证热管理系统的安全稳定运行，需提高流体控制组件100的控制精度，特别是阀元件的控制精度，因此在本实施例中，流体控制组件100还包括传感器，传感器的数量可以为多个，传感器的感应头位于通道中或者位于与通道连通的安装孔中，传感器主要用于检测通道中工作流体的温度和/或压力。如在本实施例中，传感器包括第一传感器61、第二传感器62、第三传感器63、第四传感器64、第五传感器65、第六传感器66，其中第一传感器61至第四传感器65与设置于流道板41上的传感器安装座连接，第五传感器65与贮液元件安装座47连接，第六传感器66与连接件52连接。具体地，第一传感器61用于检测第三通道403内工作流体的温 度和/或压力，第二传感器62用于检测第四通道404内工作流体的温度和/或压力，第三传感器63用于检测第五通道405内工作流体的温度和/或压力，第四传感器64用于检测第二通道408内工作流体的温度和/或压力，第五传感器65用于检测贮液元件安装座47的第三连接流道473内工作流体的温度和/或压力，或者说第五传感器65用于检测贮液元件3出口的工作流体的温度和/或压力；第六传感器66用于检测连接件的第三流道523内工作流体的温度和/或压力。
参见图1、图2以及图6，通道元件4还包括接口座，接口座具有接口，流体控制组件100通过接口座的接口实现其通道与热管理系统中其他元件对接连通。接口座与流道板41连接或接口座与流道板41可以一体成形，在本实施例中，接口座与流道板41贴合设置并通过焊接密封固定，接口的朝向相同，这样方便流体控制组件100与其他元件的对接连接。具体地，接口座包括第一接口座71、第二接口座72、第三接口座73、第四接口座74以及第五接口座75，第一接口座71具有第一接口711，第一接口711与第六通道401连通；第二接口座72具有第二接口721和第三接口722，其中第二接口721与第七通道402连通，第三接口722与第五通道405连通，这样在阀元件的控制下，第一阀元件11能够连通或不连通第一接口711和第二接口721；第三接口座73具有第四接口731和第五接口732，其中第四接口731与第三通道403连通，第五接口732与第四通道404连通，第二阀元件12能够连通第一接口711和第四接口731；第四接口座74具有第六接口741和第七接口742，其中第六接口741与第一通道406连通，第七接口742与第二通道408连通，第四阀元件14能够连通或不连通第五接口732和第六接口741；第五接口座75具有第八接口751，第八接口751与第二通道408连通，第三阀元件13能够连通或不连通第四接口731和第八接口751，第八接口751与第七接口742连通。
流体控制组件100可以应用于热管理系统，参见图1、图6以及图13，为流体控制组件100应用于热管理系统的一个实施例，在本实施例中，热管理系统200还包括压缩机201、第一换热器202、第二换热器203、蒸发器204、膨胀元件205以及第三单向阀206，其中第一换热器202即可以作 为冷凝器也可以作为蒸发器使用，第二换热器203作为冷凝器使用，压缩机201的出口与第一接口711对接连通，压缩机201的进口与第八接口751对接连通，第一换热器202的一端接口与第四接口731对接连通，第一换热器202的另一端接口与第五接口732对接连通，第二换热器203的进口与第二接口721对接连通，第二换热器203的出口与第三接口722对接连通，蒸发器204的进口通过膨胀元件205与第六接口741对接连通，蒸发器204的出口通过第三单向阀206到第七接口742单向导通。当然作为其他实施方式，还可以不包括第三单向阀206，即蒸发器204的出口与第七接口742对接连通。
参见图1、图6、图13以及图14，流体控制组件100应用于该热管理系统包括但不限于两种工作模式：
第一工作模式(图13)：第一阀元件11、第三阀元件13、第四阀元件14、第五阀元件15打开，第二阀元件12关闭，多通阀51切换至进口接头流道5211与第四流道524连通。
压缩机201出口侧的高温高压气相工作流体(如制冷剂)从第一接口711流入第六通道401，通过第一阀元件11直通流向第七通道402，并从第二接口721流向第二换热器203，经第二换热器203(冷凝器)冷凝散热后变为较高温的气液两相工作流体通过第三接口722流入第五通道405，并在第二单向阀的单向导通下进入贮液元件3的贮液腔，贮液元件3分离气相工作流体后将较高温的液相工作流体流向第一通道406，位于第一通道406的较高温的液相工作流体一部分经第四阀元件14节流膨胀后变为低温低压气液两相工作流体流向第四通道404，并通过第五接口732流入第一换热器202(此时作为蒸发器)，经第一换热器202蒸发吸热后变为较低温的气相工作流体通过第四接口731流入第三通道403，并通过第三阀元件13直通流入第二通道408；位于第一通道406的较高温的液相工作流体的另一部分，经第五阀元件15节流膨胀后变为低温低压气液两相工作流体流向第八通道407，并流入热交换元件2的第一流道，与热交换元件2的第二流道内工作流体(如冷却液)热交换吸热后变为较低温的气相工作流体流向第二通道408；第二通道408内的气相工作流体汇合后通过第八接 口751返回压缩机201进行再循环。需要指出的是，在第一工作模式中，膨胀元件205关闭，第三单向阀206处于反向截止状态。
第二工作模式(图14)：第二阀元件12、第五阀元件15打开，第一阀元件11、第三阀元件13、第四阀元件14关闭，多通阀51切换至进口接头流道5211与第四流道524连通。
压缩机201出口侧的高温高压气相工作流体(如制冷剂)从第一接口711进入第六通道401，通过第二阀元件12直通流向第三通道403，并从第四接口731流入第一换热器202(此时作为冷凝器)，经第一换热器202冷凝散热后变为较高温的气液两相工作流体通过第五接口732流入第四通道404，并在第一单向阀的单向导通下进入贮液元件3的贮液腔，贮液元件3分离气相工作流体后将较高温的液相工作流体流向第一通道406，位于第一通道406的较高温的液相工作流体一部分经第五阀元件15节流膨胀后变为低温低压气液两相工作流体流向第八通道407，并流入热交换元件2的第一流道，与热交换元件2的第二流道内工作流体(如冷却液)热交换吸热后变为较低温的气相工作流体流向第二通道408；位于第一通道406的较高温的液相工作流体的另一部分通过膨胀元件205节流膨胀后变为低温低压气液两相工作流体流向蒸发器204，经蒸发器204蒸发吸热后变为较低温的气相工作流体通过第三单向阀206流向第二通道408，第二通道408内的气相工作流体汇合后通过第八接口751返回压缩机201进行再循环。
参见图4和图6，结合上述热管理系统200的工作模式可知，第六通道401、第七通道402以及第三通道403内的工作流体多为从压缩机201流入的高温高压气相工作流体，而第四通道404和第五通道405内的工作流体多为经第一换热器202(作为冷凝器)或第二换热器203(作为冷凝器)冷凝散热后的工作流体，在本实施例中，为避免第六通道401、第七通道402、第三通道403内的高温工作流体与第四通道404、第五通道405内冷凝散热后的工作流体之间的有害换热，通道元件4还包括第一隔热槽412和第二隔热槽413，在本实施例中，沿垂直于流道板41的第一壁411的方向，第一隔热槽412自第一壁411向内远离第一壁44凹陷形成，至少部分 第七通道402和至少部分第五通道405沿第一隔热槽412周侧分布；同样的，沿垂直于第一壁44的方向，第二隔热槽413自第一壁411向内远离第一壁44凹陷形成，至少部分第三通道403和至少部分第四通道404沿第二隔热槽413周侧分布。隔热槽可以通过冷挤压在形成通道的槽腔和孔的过程中一同形成于流道板41上。当然作为其他实施方式，第一隔热槽412和第二隔热槽413还可以贯穿通道元件4设置，这样在避免通道间有害传热的同时有利于减重。需要指出的是，为避免通道之间的有害换热，通道元件4除了上述第一隔热槽412和第二隔热槽413之外，还可以有其他隔热槽。
参见图6，结合上述热管理系统200的第二工作模式，从贮液元件3流向第一通道406的液相工作流体在经膨胀元件205节流膨胀、蒸发器204蒸发吸热后变为气相工作流体流入第二通道408并返回压缩机201，为保证位于第二通道408并返回压缩机201的为气相工作流体，这就需要经第一换热器202(作为冷凝器)冷凝换热后并经贮液元件3气相分离后位于第一通道406的液相工作流体过冷，以及经膨胀元件205节流膨胀、蒸发器204蒸发吸热后位于第二通道408的气相工作流体过热。考虑到热管理系统的节能和提高换热效率，在本实施例中，至少部分第一通道406与至少部分第二通道408靠近设置，定义靠近设置为在保证强度的情况下两者之间的间隔尽可能小，这样可以使第一通道406靠近第二通道408的部分的工作流体(较高温)与第二通道408的部分的工作流体(较低温)进行热交换，从而进一步使第一通道406内工作流体的冷凝散热，保证其工作流体的过冷，同时进一步使第二通道408内工作流体的蒸发吸热，保证其过热。具体地，在本实施例中，第一通道406包括第一通道段4061，相应地，第二通道408包括第二通道段4081，第一通道段4061靠近第二通道段4081设置，进一步地，第一通道段4061呈U型设置，第二通道段4081同样呈U型设置，第一通道段4061围绕第二通道段4081形成且位于第二通道段4081的外侧。设置第一通道段4061和第二通道段4081为U型，一方面有利于增大两者间的换热面积，另一方面还有利于使通道结构紧凑，当然作为其他实施方式，第一通道段4061和第二通道段4081还可以为其 他形状。当然作为其他实施方式，经第一换热器(作为冷凝器)或经第二换热器(作为冷凝器)冷凝散热后的通道内的工作流体可能不经过贮液元件3气液分离就直接流经膨胀元件节流膨胀、蒸发器蒸发吸热后通过通道回流至压缩机，因此，考虑到其他实施方式的可能，可以使位于冷凝器后且位于膨胀元件前的通道(如第一通道)的至少部分与位于蒸发器后的通道(如第二通道)的至少部分靠近设置，这里所述的前和后指：以压缩机的出口为起点，压缩机的入口为终点，沿制冷剂的流向，靠近压缩机的出口为前，远离压缩机的出口为后。这里需要指出的是：当第一换热器作为冷凝器、第二换热器作为冷凝器时，第一换热器和第二换热器可以统称为冷凝器；膨胀元件可以为热力膨胀阀、电子膨胀阀、毛细管等其他本领域技术人员已知的具有节流膨胀效果的元件。通过利用通道间的换热来提高工作流体的过冷和过热，相比与在系统中通过增加中间换热器实现工作流体的过冷和过热，有利于充分利用通道间的热能，减小系统能耗，提高换热效率。
另外，根据流体控制组件的通道的不同用途，可以将通道分为连通通道和换热通道，定义连通通道主要用于实现工作流体的流通，换热通道则在进行工作流体流通的同时，还能够进行通道间工作流体的热交换。如在本实施例中，根据工作模式可知，第三通道至第八通道为连通通道，第一通道和第二通道为换热通道。可以理解的是：作为扩展实施例，冷凝器、蒸发器、膨胀元件的至少其中之一还可以集成设置于流体控制组件上。在一个具体的实施方式，流体控制组件包括流体管理元件和通道元件，流体管理元件包括冷凝器、贮液元件的至少其中之一，流体管理元件与通道元件连接，这里所述的连接包括直接连接和间接连接，间接连接可以是流体管理元件与通道元件通过管路连接。换热通道包括第一通道和第二通道，流体管理元件的流道与连通通道连通，流体管理元件的流道连通第一通道，第一通道的至少部分与第二通道的至少部分靠近设置，第一通道与第二通道相互靠近部分内的工作流体能够热交换。在实际应用时，高温高压的工作流体从连通通道经流体管理元件后进入第一通道，热管理系统的工作流体经蒸发吸热后进入第二通道，第一通道和第二通道内工作流体在二者相 互靠近处进行热交换，不仅可以提高热管理系统的效率，而且流体控制组件具有连通通道和换热通道，减少了中间换热器的连接，可以使流体控制组件结构紧凑，也有利于热管理系统的布局以及小型化。
在另一个具体的实施方式，流体控制组件还可以包括蒸发器和膨胀元件的至少其中之一，以蒸发器和膨胀元件均包括为例进行介绍，蒸发器和膨胀元件可以分别与通道元件连接，也可以蒸发器和膨胀元件集成后与通道元件连接，第一通道通过但不限于膨胀元件的流道和第二换热器的流道与第二通道连通，这里所述的不限于包括接管或者其他功能件如开关阀等，不再详细描述。进一步的，连通通道包括第一连接口，第一通道包括第二连接口，第一连接口、第二连接口位于通道元件的相同一侧；这样方便通道元件与贮液元件、冷凝器的连接与集成，有利于流体控制组件结构紧凑。第一通道包括第三连接口，第二通道包括第四连接口，第三连接口、第四连接口位于通道元件的相同一侧。这样方便通道元件与膨胀元件、蒸发器的连接与集成，有利于流体控制组件结构紧凑。需要指出的是：这里所述的连接口包括上文所述的用于与贮液元件连通的孔的开口和用于与冷凝器、蒸发器、膨胀元件连通的接口。
需要说明的是：以上实施例仅用于说明本发明而并非限制本发明所描述的技术方案，尽管本说明书参照上述的实施例对本发明已进行了详细的说明，但是，本领域的普通技术人员应当理解，所属技术领域的技术人员仍然可以对本发明进行修改或者等同替换，而一切不脱离本发明的精神和范围的技术方案及其改进，均应涵盖在本发明的权利要求范围内。
