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，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。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。
下文的公开提供了许多不同的实施例或例子用来实现本申请的不同结构。为了简化本申请的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本申请。此外，本申请可以在不同例子中重复参考数字和/或字母。这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。此外，本申请提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的可应用于性和/或其他材料的使用。
下面，参照图1-图11，描述根据本申请实施例的多通道切换阀100。
如图1所示，根据本申请实施例的多通道切换阀100，包括：壳体10、阀芯20和密封件30。
具体而言，如图1和图2所示，壳体10周向上设有多个流通通孔11，阀芯20可转动地设在壳体10内，阀芯20设有至少一个切换通道21，切换通道21与其中两个流通通孔11连通，阀芯20被配置为在阀芯20转动时切换通道21与不同的流通通孔11切换连通，密封件30包括本体31，本体31设有多个避让通孔311，多个避让通孔311与多个流通通孔11一一对应连通，其中，本体31被构造成成型状态为弧形板的一体加工成型件，密封件30的圆心角小于等于180°（如图7所示，其中A表示密封件30的圆心角），密封件30分别与阀芯20和壳体10接触。
可以理解的是，壳体10上的流通通孔11可以与外部管道连通，外部管道内具有流动的介质，由此，介质可以从流通通孔11进入多通道切换阀100内部或从多通道切换阀100内部流出，以实现多通道切换阀100向外部排放介质或吸取介质，其中，介质可以为水或防冻液或其他液体，在此不做限定。
可选地，如图1-图3、图8和图9所示，壳体10设有安装座13，即壳体10可通过安装座13与其它结构相连，以便于固定壳体10，增强壳体10的结构稳定性。
进一步地，阀芯20安装于壳体10内，且阀芯20可构造为柱状，阀芯20可在壳体10内沿自身轴线转动，其中，如图4所示，阀芯20设有至少一个切换通道21，切换通道21用于与多个流通通孔11中的两个流通通孔11连通，且阀芯20转动以使得切换通道21与不同的流通通孔11切换连通，其中，在切换通道21与不同的流通通孔11连通时，介质可通过不同的流通通孔11进入多通道切换阀100内部或从多通道切换阀100内部流出，使得多通道切换阀100具有不同的工作模式。
换言之，通过在阀芯20上设置切换通道21，且通过转动阀芯20以使切换通道21与不同的流通通孔11切换连通，从而便于通过转动阀芯20实现多通道切换阀100的不同的流道之间的切换，进而实现多通道切换阀100的不同工作模式，示例性地，通过调节阀芯20的旋转角度，能够实现多通道切换阀100的不同的流道之间的切换和流量的控制，进而控制外部管道中的流体介质的流量。
需要说明的是，在现有技术中，通常设置多个简单的多通阀联合完成多种模式的切换，导致简单的多通阀过多，增加成本，且控制难度增大，而本申请中，相比较现有技术中多个多通阀的方式，在相同的体积下，能够实现更多种工作模式，利于降低控制难度及成本。
更进一步地，如图9所示，密封件30安装于阀芯20与壳体10之间，且密封件30分别与阀芯20和壳体10接触，从而通过密封件30对阀芯20和壳体10之间的流道进行密封，进而保证在阀芯20的转动过程中实现阀芯20和密封件30、密封件30和壳体10之间的密封，防止阀芯20和壳体10之间形成的流道内部的介质泄漏到阀体内而导致多通道切换阀100内漏和失效，进而避免介质内部混流、或多通道切换阀100的调节功能丧失。
其中，如图5和图6所示，密封件30包括本体31，本体31设有多个避让通孔311，多个避让通孔311与多个流通通孔11一一对应连通，即避让通孔311适于连通流通通孔11与至少一个切换通道21，以便于介质能够通过避让通孔311流入或流出切换通道21，从而保证介质能够稳定地流动。
本体31被构造成成型状态为弧形板的一体加工成型件，且密封件30的圆心角不大于180°。
可选地，密封件30可以按其与阀芯20的最终装配形态注塑成型，从而便于降低密封件30的加工难度，其中，密封件30的内壁与阀芯20的结构相适配，以便于降低阀芯20与密封件30的装配难度。
由此，在实际装配时，不需对其进行预卷，可直接将密封件30装入壳体10内，便于降低密封件30的装配难度，利于实现自动化装配，且能够使得密封件30和阀芯20接触一侧与密封件30和壳体10接触的一侧的变形量一致，避免密封件30内外侧错位、变形，从而增强密封件30的密封性，同时，保证密封件30能够均匀的受力，从而避免密封件30内部产生额外内应力，利于延长密封件30的使用寿命。
根据本申请实施例的多通道切换阀100，通过将本体31构造为一体加工成型的弧形板，从而不需对密封件30进行预卷，能够保证密封件30和阀芯20接触一侧与密封件30和壳体10接触的一侧的变形量一致，避免密封件30内外侧错位、变形，从而增强密封件30的密封性，同时，便于降低密封件30的装配难度，利于实现自动化装配。
可选地，密封件30的材料为弹性材料。示例性地，密封件30为橡胶材料，在本申请中，密封件30的材料为EPDM（Ethylene Propylene Diene tripolymer，三元乙丙橡胶），使得本申请中的密封件30具有性价比高、优异的耐老化特性、优异的耐化学药品特性、优良的绝缘性能和适用温度范围广的特性。
示例性地，密封件30的材质为橡胶材料，且阀芯20与密封件30过盈配合，由此，使得阀芯20可挤压密封件30使得密封件30夹设于阀芯20与壳体10之间，以对密封件30进行固定，增强密封件30的结构稳定性，且通过设置阀芯20与密封件30过盈配合，不需采用结构限位等方式来单独固定密封垫，便于简化壳体10与密封件30的连接结构，以及利于降低装配难度，利于实现自动化装配。需要说明的是，上述密封件30的材质以及固定方式仅用于举例说明，并不代表对此的限制。
进一步地，密封件30通过多个凸筋320与壳体10接触，即凸筋320设于密封件30朝向壳体10的一侧，且凸筋320与壳体10的内周壁相抵，示例性地，凸筋320为弹性材料制成，例如橡胶等，且凸筋320与壳体10的内周壁过盈配合。
在实际装配后，即阀芯20朝向壳体10的内周壁压缩密封件30，以使凸筋320弹性抵压于壳体10的内周壁。由此，通过设置凸筋320，能够加大密封件30压缩后的反作用力，增加了密封件30的抗压变能力，防止出现密封间隙而导致密封性能下降的问题，从而进一步增加了密封的可靠性。
在一些实施例中，部分凸筋320的延伸方向与密封件30的轴向平行和/或部分凸筋320的延伸方向与密封件30的周向平行。
例如图6所示，部分凸筋320的延伸方向与密封件30的轴向平行，以便于在密封件30的轴向上增强密封件30与壳体10之间的密封效果，或者部分凸筋320的延伸方向与密封件30的周向平行，以便于在密封件30的周向上增强密封件30与壳体10之间的密封效果，再或者，部分凸筋320的延伸方向与密封件30的轴向平行，且另一部分凸筋320的延伸方向与密封件30的周向平行，以便于在密封件30的轴向和周向上均增强密封件30与壳体10之间的密封效果。
进一步地，如图6所示，多个凸筋320包括第一筋条32，任意相邻的避让通孔311之间设有第一筋条32。
其中，第一筋条32可沿本体31的周向延伸，或者第一筋条32可沿本体31的轴向延伸。示例性地，如图6所示，部分第一筋条32沿本体31的轴向延伸，且部分第一筋条32沿本体31的周向均匀间隔开分布，另一部分第一筋条32沿本体31的周向延伸，且另一部分第一筋条32沿本体31的轴向均匀间隔开分布。
由此，便于通过多个第一筋条32，能够在每个避让通孔311与对应的流通通孔11之间的流道处起到密封作用，即能够对每个阀芯20与壳体10之间的流道单独进行密封，从而增强单个流道的密封性，且能够避免单个流道的密封失效对其它流道的密封性产生影响。
在一些实施例中，如图7所示，第一筋条32与壳体10的接触面形成为弧形面321。
需要说明的是，弧形面321适于与壳体10的内周壁的截面形状相匹配，从而保证第一筋条32能够与壳体10的内周壁紧密贴合，防止出现密封间隙，增强密封件30的密封效果。可以理解的是，当本体31为一体注塑成型件时，弧形面321还便于本体31的脱模。
示例性地，如图7所示，在与第一筋条32的延伸方向垂直的方向上，第一筋条32的横截面包括平行设置的两个侧壁322，两个侧壁322分别与弧形面321的两端相连。可以理解的是，当本体31为一体注塑成型件时，平行设置的两个侧壁322和弧形面还便于本体31的脱模。
由此，使得第一筋条32朝向壳体10的内周壁的接触面为弧形面321，以增大第一筋条32与壳体10的内周壁的接触面积，进而使得第一筋条32能够与壳体10的内周壁紧密贴合，防止出现密封间隙，增强密封件30的密封效果。
在一些实施例中，任意相邻的避让通孔311之间设有多个间隔设置的第一筋条32。示例性地，相邻的凸筋320的间隙大于1mm，从而在增强密封件30的密封性的同时，不会影响密封件30的弹性，利于使得阀芯20的扭力保持在较小的范围内
在一些实施例中，如图2和图3所示，壳体10的内壁面设有凹槽12，多个流通通孔11均设在凹槽12的底壁内，从而减少对壳体10内的安装空间的占用，利于降低壳体10的重量，实现多通道切换阀100的轻量化、小型化设计。
其中，密封件30至少与凹槽12的底壁接触。可以理解的是，第一筋条32与凹槽12的底壁接触，以便于密封件30能够在阀芯20与壳体10之间起到更好的密封作用，且在实际装配后，阀芯20压缩密封件30进入凹槽12内，以通过凹槽12对密封件30进行限位以及固定，从而增强密封件30的结构稳定性，且利于节省密封件30在壳体10内所占用的安装空间，进而实现多通道切换阀100的轻量化、小型化设计。
进一步地，凹槽12设有环形的侧壁，侧壁围绕多个流通通孔11设置，密封件30与环形的侧壁接触。
由此，在将密封件30装入凹槽12后，能够使得密封件30与环形的侧壁紧密贴合，进而增大密封件30与壳体10的接触面积，进而增强密封件30的密封效果。
在一些实施例中，密封件30还包括耐磨层，耐磨层设在本体31上，耐磨层与阀芯20接触。
换言之，耐磨层位于密封件30朝向阀芯20的一侧，从而便于减少阀芯20在转动过程中对密封件30的磨损，利于起到保护密封件30的作用，进而提高密封可靠性以及利于延长密封件30的使用寿命。
需要说明的是，在多通道切换阀100的内部的阀芯20和壳体10之间设置有密封件30，密封件30用于阀芯20阀壳体10之间的流道密封，要求在阀芯20旋转过程中实现阀芯20和密封件30、密封件30和壳体10之间的密封，防止防冻液介质泄漏到阀体内，导致电子多通水阀内漏和失效，造成冷却介质内部混流，或热管理温度调节功能丧失。
另外，由于阀芯20正常工作状态下，在产品生命周期内需要往复地旋转，密封件30使用时间久了会出现磨损，导致多通道切换阀100泄漏，因此，在本申请中，将耐磨层位于密封件30朝向阀芯20的一侧，以减少阀芯20在转动过程中对本体31的磨损，利于起到保护密封件30的作用，进而利于延长密封件30的使用寿命。
其中，耐磨层的材料为摩擦系数小和耐磨的材料，例如：耐磨层可以采用氟塑料膜、或PTFE（聚四氟乙烯）类材料等，由此，便于使得耐磨层具有耐磨和摩擦系数小的效果，从而便于减少阀芯20在转动过程中对本体31的磨损，且利于减小密封件30与阀芯20之间的摩擦力，从而在密封件30与阀芯20之间起到润滑的作用，延长密封件30的使用寿命，同时，能够使得阀芯20的扭力保持在一个较小的范围内。
当然，耐磨层的材料也可以采用符合性能要求的任何材料，在此不做限定。
在另一些实施例中，耐磨层构造为包覆膜，包覆膜可以采用氟塑料膜，如PTFE（聚四氟乙烯）类材料，以使包覆膜具有耐磨、润滑等性能，有利于改善其摩擦磨损性能。
在实际生产时，对包覆膜朝向本体31的一侧进行化学处理，以及对本体31朝向包覆膜的一侧进行化学处理，接着，将包覆膜与本体31进行装配并注塑成型，以使包覆膜与本体31的形状相同，然后通过冲压工具对包覆膜进行冲压，以使包覆膜上形成有与本体31的避让通孔311对应的通孔。
在一些实施例中，如图5所示，多个避让通孔311排列成多行多列，在本体31的周向上设置的避让通孔311的个数小于在本体31的轴向上设置的避让通孔311的个数。
举例而言，如图5所示，避让通孔311设有六个，其中，在本体31的轴向上形成为三行两列的分布方式，即在本体31的周向上每行具有两个间隔开分布的避让通孔311，且在本体31的轴向上每列具有三个间隔开分布的避让通孔311。
由此，便于控制本体31的周向尺寸，利于节省本体31的材料，实现本体31的小型化和轻量化设计。
在一些实施例中，切换通道21为多个，如图2所示，多个切换通道21包括第一连通通道211和第二连通通道212，第一连通通道211沿阀芯20的外周壁延伸，第二连通通道212包括内层流道和两个连通口，两个连通口通过内层流道连通，两个连通口位于阀芯20的外周壁上，内层流道位于阀芯20的内部，阀芯20转动以使得第一连通通道211与不同的流通通孔11切换连通和/或第二连通通道212与不同的流通通孔11切换连通。
可以理解的是，第一连通通道211用于连通两个流通通孔11，通过在阀芯20的外周壁上设置第一连通通道211，且第一连通通道211连通两个流通通孔11，阀芯20转动使第一连通通道211与不同的流通通孔11连通，从而实现对模式的切换。在本申请的一些示例中，第一连通通道211可以设置为连通两个靠近的流通通孔11，方便阀芯20的生产，例如，两个流通通孔11相邻。
第二连通通道212用于连通两个流通通孔11，第二连通通道212包括内层流道和两个连通口，两个连通口通过内层流道连通，两个连通口位于阀芯20的外周壁上，内层流道位于阀芯20的内部，通过在阀芯20内部设置内层流道，充分利用阀芯20所占的空间，在阀芯20外周壁设置第一连通通道211的基础上，进一步增加可选择的模式数量，从而满足更多种工作需求。
同时，第二连通通道212的内层流道设在阀芯20的内部可以满足复杂情况下的两个流通通孔11的连通，例如，处于对角线上的两个流通通孔11直接通过阀芯20外周壁上的第一连通通道211连通必定影响对角线两侧的两个流通通孔11的连通，通过将内层流道设在阀芯20的内部，可以避免此种问题，降低阀芯20的设计难度。
阀芯20转动以使得第一连通通道211与不同的流通通孔11切换连通和/或第二连通通道212与不同的流通通孔11切换连通，通过转动阀芯20实现多种模式，相比较相关技术中多个多通阀的方式，在相同的体积下，实现更多种模式，降低控制难度及成本。
例如，阀芯20转动使得第一连通通道211与不同的流通通孔11切换连通，第二连通通道212的两个连通口一直未与流通通孔11连接；或者，阀芯20转动以使得第二连通通道212与不同的流通通孔11切换连通，第一连通通道211一直未与流通通孔11连通；再或者，阀芯20转动以使得第一连通通道211与不同的流通通孔11切换连通和第二连通通道212与不同的流通通孔11切换连通，单独一个阀芯20的转动便同时实现第一连通通道211、第二连通通道212与不同的流通通孔11的连通。
由此，通过设置第一连通通道211与第二连通通道212，且第一连通通道211与第二连通通道212分别分布在阀芯20的外周壁与内部，充分利用阀芯20的空间，提高空间利用率，在相同的体积限制下，实现更多种模式的切换，无需使用多个控制阀进行流路切换，降低成本与控制难度；通过设置多个流通通孔11与第一连通通道211、第二连通通道212切换连通，进一步增加可切换的模式，进一步降低成本与控制难度。
进一步地，阀芯20的一部分形成为中空的结构以限定出内层流道，阀芯20的周壁设有多个连通口，阀芯20转动使得连通口与避让通孔311连通或者错位设置。其中多个连通口可以为两个及以上，从而充分利用阀芯20所占的空间，使得第二连通通道212的加工成型方式简单可靠。需要进行说明的是，当阀芯20的周壁上的连通口的个数为三个及以上时，任意两个连通口可以与内层流道限定出一条第二连通通道212，即此时第二连通通道212的个数为两个及以上，从而可以增加多通道切换阀100的切换模式，从而满足更多种工作需求。
示例性地，两个连通口位于阀芯20的外周壁上，内层流道位于阀芯20的内部，通过在阀芯20内部设置内层流道，能够充分利用阀芯20所占的空间，在阀芯20外周壁设置第一连通通道211的基础上，进一步增加可选择的模式数量，从而满足更多种工作需求。
同时，第二连通通道212的内层流道设在阀芯20的内部可以满足复杂情况下的两个流通通孔11的连通，例如，处于对角线上的两个流通通孔11直接通过阀芯20外周壁上的第一连通通道211连通必定影响对角线两侧的两个流通通孔11的连通，通过将内层流道设在阀芯20的内部，可以避免此种问题，降低阀芯20的设计难度。
可选地，如图1和图8所示，多通道切换阀100还包括：执行器装置40和阀盖50。
具体而言，执行器装置40设置在壳体10的一端且与阀芯20动力连接，阀盖50设于壳体10的另一端，其中，执行器装置40由电机、减速齿轮组和控制电路板组成，车辆适于通过与控制电路板通讯连接，且用于驱动执行器装置40内的电机输出驱动力，驱动力经过减速齿轮组后输出扭矩到阀芯轴22，进而带动阀芯20在壳体10内转动。
其中，当多通道切换阀100关闭时，即流通通孔11与切换通道21不导通时，多通道切换阀100处于关闭状态。当多通道切换阀100工作时，执行器装置40驱动阀芯20转动，且当阀芯20转过一定角度后，其切换通道21与流通通孔11开始导通，继续转动阀芯20，切换通道21与流通通孔11的导通的面积逐渐增大，其能够通过的流量也随之增大。由此，通过控制阀芯20的转动角度，可以实现多通道切换阀100多个工作模式的切换和流量控制。
本申请还提出了一种热管理系统1001。
如图10所示，根据本申请实施例的热管理系统1001，包括：汇流板200和多通道切换阀100。
汇流板200内设有用于流通介质的多个流道201，多通道切换阀100为上述任一项实施例的多通道切换阀100，多通道切换阀100设在汇流板200上，多个流道201分别与多个流通通孔11相连，阀芯20转动以控制多个流道201切换连通以控制热管理系统1001进行模式切换。
本申请还提出了一种车辆1000。
如图11所示，根据本申请实施例的车辆1000，包括上述任一项实施例所述的热管理系统1001。
根据本申请实施例的车辆1000，其热管理系统1001的多通道切换阀100通过将本体31构造为一体加工成型的弧形板，从而不需对密封件30进行预卷，能够保证密封件30和阀芯20接触一侧与密封件30和壳体10接触的一侧的变形量一致，避免密封件30内外侧错位、变形，从而增强密封件30的密封性，同时，便于降低密封件30的装配难度，利于实现自动化装配，并且可降低整个系统的成本和发生内泄漏故障的风险，同时起到小型化，便于整车布置的效用。
这里，车辆1000可以是新能源车辆，在一些实施例中，新能源车辆可以是以电机作为主驱动力的纯电动车辆，在另一些实施例中，新能源车辆还可以是以内燃机和电机同时作为主驱动力的混合动力车辆。关于上述实施例中提及的为新能源车辆提供驱动动力的内燃机和电机，其中内燃机可以采用汽油、柴油、氢气等作为燃料，而为电机提供电能的方式可以采用动力电池、氢燃料电池等，这里不作特殊限定。需要说明，这里仅仅是对新能源车辆等结构作出的示例性说明，并非是限定本申请的保护范围。
