下面参考说明书附图描述本申请实施例的多通切换阀100，多通切换阀100集成度高、所需安装空间小、安装效率高、通路切换模式多样、控制方便。
根据本申请实施例的一种多通切换阀100，如图1所示，包括阀壳10、多个阀芯20和多个驱动机构40。
其中，如图1所示，阀壳10上设有多个流通口11，换热介质可以从流通口11进入多通切换阀100内部或从多通切换阀100内部流出（如图3所示，带有箭头的线条为换热介质的流动路径），在不同流通口11连通时可以实现多种模式。本申请的流通口11可以连接外部管道，以实现向阀壳10外部排放换热介质或向阀壳10中吸入换热介质。这里还需要说明的是，换热介质为水或其他带有盐溶液的液体。
如图2所示，多个阀芯20可转动地设在阀壳10内，那么至少一个阀芯20可相对于阀壳10转动，从而改变多通切换阀100的状态。
如图3所示，阀芯20均具有第一连通通道21，每条第一连通通道21均可连通两个流通口11，两个流通口11中的一个可作为换热介质的入口，另一个则作为换热介质的排出口，因此每个阀芯20转动后，其内的第一连通通道21均可与不同的流通口11相连通，改变经过该转动阀芯20时，换热介质的流动路径，改变换热介质的流动方向，实现改变不同的换热循环系统的换热效果。
如图3所示，至少两个阀芯20中设有第二连通通道22，至少相邻两个阀芯20中的第二连通通道22相连通，每个阀芯20中的第二连通通道22分别连通至少一个流通口11。当其中一个阀芯20的流通口11中流入换热介质时，换热介质经过两个阀芯20的第二连通通道22则可从另一个阀芯20对应的流通口11向外排出，使换热介质不仅可以在同一个阀芯20对应的流通口11中排入排出，还可以与其他阀芯20联用，而实现更多路径的换热介质的排入排出，使多通切换阀100的通路切换模式多样、丰富，能适应更多的需求。
当多个阀芯20转动时，可使第一连通通道21相对于不同的流通口11进行切换，也可以使相邻的两个阀芯20的第二连通通道22相对于不同的流通口11进行切换，实现不同的进液、排液的流通口11的切换连通，并形成不同的换热介质流动路径切换。
如图1所示，每个驱动机构40分别驱动至少一个阀芯20转动，也就是说，一个驱动机构40可同时驱动两个或更多个阀芯20形成转动，例如在具体示例中，同一个驱动机构40的输出端分别连接多个阀芯20；或者同一个驱动机构40具有多个输出端，实现对多个阀芯20的驱动；一个驱动机构40也可以仅驱动一个阀芯20进行转动，使每个阀芯20均能被单独控制、精准控制。
在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
由上述结构可知，本申请实施例的多通切换阀100，在驱动机构40的驱动下，至少有一个阀芯20可相对于阀壳10转动，与此同时，该转动的阀芯20所对应的第一连通通道21与不同的流通口11相连通，有效改变换热介质的流动路径，形成不同路径的进出液切换。
当多个驱动机构40同时驱动不同的阀芯20转动时，则可使各个阀芯20内的第一连通通道21均与不同的流通口11进行切换，可形成更多的进出液路径，使多通切换阀100的通路模式切换方便、模式多样。
对于阀芯20相对于阀壳10转动的过程中，第一连通通道21未与流通口11完全对中，而是部分相连的情况，可实现第一连通通道21不同大小的进出液流量的控制，控制流经各个阀芯20的第一连通通道21的换热介质的流动速率、出液量和进液量。
当两个阀芯20中的第二连通通道22连通后，换热介质可进一步从其中一个阀芯20对应的流通口11进入，并流入另一个阀芯20中进行再分配，之后从另一个阀芯20对应的流通口11向外流出，使换热介质可以在不同的阀芯20之间进行流动，进一步增加了整个多通切换阀100的流通通路模式，提升了同一个多通切换阀100对于不同的换热循环系统的切换和控制效果。
相关技术中，为了适应更多数量的换热循环系统的控制，通常增加电子水阀的个数来实现多循环回路的需求。不同的电子水阀需要占用较多的安装空间，并需要分别进行装配操作，单独布置控制线路，操作复杂、集成化程度低。
可以理解的是，相比于现有技术中对于控制较多数量的换热循环系统时采用增加电子水阀的个数的方案，本申请实施例的多通切换阀100整个阀体集成度高，占用安装体积少、安装操作方便、通路模式多样且切换控制方便。
本申请的描述中，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，用于区别描述特征，无顺序之分，无轻重之分。
在一些实施例中，驱动机构40为伺服电机、旋转电机，伺服电机控制精确。
在本申请的一些实施例中，如图2所示，还包括分隔件50，阀壳10通过分隔件50分隔为多个腔体，每个腔体中均设有一个阀芯20，位于各个腔体中的阀芯20具有相对稳定的工作环境，方便对各个阀芯20进行控制。
进一步地，如图2和图3所示，相邻的两个腔体之间的分隔件50上设有通口51，两个阀芯20的第二连通通道22通过通口51连通，在这些示例中，通过设置通口51可使位于两个腔体中的阀芯20内的换热介质在两者之间流动，使换热介质不仅能在各个腔体中的阀芯20内通过第一连通通道21和相对应的流通口11形成进出液；还能使换热介质在相邻的两个腔体内的阀芯20之间通过第二连通通道22和相对应的流通口11形成进出液，使换热介质的流动路径多样化。
为了方便描述，如图4至图7所示，将相邻的两个腔体分别记为第一腔体101和第二腔体102，并将第一腔体101中的阀芯20记为第一阀芯202，第二腔体102中的阀芯20记为第二阀芯203，且将驱动第一阀芯202的驱动机构40记为第一驱动机构41，驱动第二阀芯203的驱动机构40记为第二驱动机构42。
在一些实施例中，如图4和图5所示，第一腔体101中的第一阀芯202的转动轴201和第二腔体102中的第二阀芯203的转动轴201共轴线设置，也就是说，第一阀芯202的转动轴线与第二阀芯203的转动轴线共线。
进一步地，第一阀芯202和第二阀芯203分别设在相邻的第一腔体101和第二腔体102中；第一阀芯202与第一驱动机构41相连，第二阀芯203与第二驱动机构42相连，第一驱动机构41和第二驱动机构42分别设在阀壳10的不同侧，方便与第一阀芯202和第二阀芯203进行连接，可以理解的是，若将第一驱动机构41和第二驱动机构42分别设在阀壳10的同一侧，要想使两个阀芯20的转动轴201共线，那么第一驱动机构41和第二驱动机构42的输出端位于同一处，两个驱动机构40的输出端得设计为嵌套形式才能实现，这将使驱动机构40的结构过于复杂，也不方便腔体中阀芯20的布置。因此，本申请中要想使第一阀芯202和第二阀芯203共轴线转动，则选择将第一驱动机构41和第二驱动机构42分别设在阀壳10的不同侧。
在具体示例中，第一驱动机构41和第二驱动机构42可分别设在阀壳10的相对两侧，如左侧面和右侧面，或者前侧面和后侧面，亦或为上侧面和下侧面。
在如图4所示出的多通切换阀100第一方面的示例中，第一阀芯202和第二阀芯203相邻设置在两个腔体中，第二阀芯203设在第一阀芯202的轴向上，分隔件50设在阀芯20的轴向一端。那么，在这些示例中，第一阀芯202由第一驱动机构41驱动并可在第一腔体101中转动，第二阀芯203由第二驱动机构42驱动并可在第二腔体102中转动，分隔件50上的通口51使第一阀芯202中的第二连通通道22、第二阀芯203中的第二连通通道22相连，此时，换热介质则可从第二阀芯203中进入第一阀芯202中，再从第一阀芯202对应的流通口11向外排出；或者，换热介质可从第一阀芯202中进入第二阀芯203中，再从第二阀芯203对应的流通口11向外排出。这些示例中的分隔件50位于第一阀芯202和第二阀芯203的轴向上，分隔件50布置方便、结构简单；分隔件50可使第一阀芯202和第二阀芯203在轴向上的转动彼此分隔，两个阀芯20可各自独立转动、互不干扰。
在第一方面的示例中，通口51可以设在分隔件50的中部或者边缘，此时设在第一腔体101和第二腔体102中的第二连通通道22也需要对应通口51设计自身的延伸方向，使第二连通通道22能够与通口51保持连通，确保换热介质流动顺畅。
有利地，如图3所示，为了提升分隔件50的通口51与第二连通通道22连通时两者之间连接紧密，将分隔件50的通口51处设置翻边52，翻边52向着其中一个阀芯20的第二连通通道22的通道壁延伸，使翻边52能与通道壁配合紧密，确保换热介质在第二连通通道22中通过通口51时不发生串流或漏液。
在如图5所示的第二方面多通切换阀100的示例中，第一阀芯202和第二阀芯203相邻设置在第一腔体101和第二腔体102中，第一阀芯202的转动轴201和第二阀芯203的转动轴201共轴线设置。第一阀芯202和第二阀芯203中其中一个阀芯20外套在另一个阀芯20的外侧，例如在图5中为第二阀芯203外套在第一阀芯202的外侧，分隔件50围设在第一阀芯202周侧，使第二阀芯203和第一阀芯202形成为内外嵌套型的布置结构形式。分隔件50设在第一阀芯202的外周，而同时设在第二阀芯203的内周壁，使第一阀芯202和第二阀芯203均可在各自的腔体中独立转动。在这些示例中，由于两个阀芯20呈内外嵌套设置，因此，可极大地节约布置两个阀芯20所需的轴向的尺寸，使第一阀芯202和第二阀芯203布置时结构紧凑。
在第二方面的示例中，分隔件50上的通口51选择设在分隔件50的侧面，与通口51连通的第二连通通道22的至少部分需要沿第一阀芯202以及第二阀芯203的径向延伸，实现与通口51进行对接连通，确保换热介质流动顺畅。此时第二阀芯203和第一阀芯202的轴向一端的分隔件50上可不开设通口51，两个阀芯20的转动轴201在轴向上形成可靠的分隔。当第一阀芯202旋转后其内的第二连通通道22对准通口51，且第二阀芯203旋转后其内的第二连通通道22也同时对准通口51时，两者之间的换热介质可连通，并形成不同阀芯20之间的流通路径。
在一些实施例中，如图6和图7所示，相邻的两个腔体（可以为第一腔体101和第二腔体102）中的阀芯20（可以为第一阀芯202和第二阀芯203）的转动轴201平行设置，也就是说，第一阀芯202的转动轴线和第二阀芯203的转动轴线彼此平行。
进一步地，第一阀芯202和第二阀芯203分别设在相邻的第一腔体101和第二腔体102中；第一阀芯202与第一驱动机构41相连，第二阀芯203与第二驱动机构42相连，第一驱动机构41和第二驱动机构42分别设在阀壳10上，使阀壳10为第一驱动机构41和第二驱动机构42的安装提供了支撑，也使驱动机构40在带动阀芯20转动时，阀芯20可相对于阀壳10稳定旋转，不偏移。两个驱动机构40可设在阀壳10的同侧或不同侧，可根据实际的安装空间以及环境配合件来选择。
在如图6所示出的多通切换阀100第三方面的示例中，第一阀芯202和第二阀芯203相邻设置在两个腔体中，同时，第一阀芯202和第二阀芯203成行并排布置，分隔件50设在两个阀芯20之间。例如在具体示例中，第一阀芯202和第二阀芯203沿左右方向并排布置，此时的分隔件50则设在两者朝向彼此的一侧。分隔件50所在面可平行于转动轴201所在面，使阀壳10中形成两个形状规则的第一腔体101和第二腔体102，方便第一阀芯202和第二阀芯203中的第二连通通道22分别与分隔件50之间进行连通，也方便在第二连通通道22未与通口51连通时封堵通口51。
在这些示例中，为了方便第一阀芯202和第二阀芯203中的第二连通通道22同时与通口51连通，第一驱动机构41驱动第一阀芯202逆时针旋转时，第二驱动机构42则驱动第二阀芯203顺时针旋转，使两个阀芯20中的第二连通通道22能更快地与通口51形成连通。
在第三方面的示例中，通口51可选择设在分隔件50的中部或边缘区域，与此同时，两个阀芯20中的第二连通通道22也需要对应通口51的位置而改变其延伸方向，确保两个阀芯20在转动的过程中，能同时与通口51形成连通。
在第三方面的示例中，第一驱动机构41和第二驱动机构42可同时布置在阀壳10的同一侧，方便将阀壳10的其他侧留出来布置流通口11，使流通口11可布置的区域更多，也使第一驱动机构41和第二驱动机构42的装配和控制更加方便。
在如图7所示的第四方面多通切换阀100的示例中，第一阀芯202和第二阀芯203相邻设置在第一腔体101和第二腔体102中，第一阀芯202的转动轴201和第二阀芯203的转动轴201相平行，且两个转动轴201在轴向上错开设置在阀壳10中，分隔件50设在阀芯20的轴向。那么在这些示例中，两个阀芯20的布置形式更加灵活，此时的阀壳10可相应地设置为不规则阀壳，以适应更加多变的安装环境。
在第四方面的示例中，通口51选择设在分隔件50的边缘区域，使两个转动轴201能够在物理空间上相分隔，也使第二连通通道22能够沿着阀芯20的轴向延伸与通口51形成连通。
在第四方面的示例中，第一驱动机构41和第二驱动机构42分别设在阀壳10的不同侧，例如为左右两侧面，使阀壳10更容易以不同的阀芯20、第一驱动机构41为单元而设计结构、进行布置。
当然，本申请的多通切换阀100也不局限于上述四种示例中的布置形式，例如，在本申请第五方面多通切换阀100的示例中，如图8所示，还可以为第一阀芯202的转动轴线和第二阀芯203的转动轴线成角度布置，此时其中一个阀芯20上的第二连通通道22至少部分可沿着径向延伸并与通口51相连，而另一个阀芯20上的第二连通通道22则可沿着轴向延伸并与通口51相连，这里不做具体限制。
这里，两个阀芯20的转动轴201之间的夹角可以为90度、锐角或钝角，可根据实际情况进行选择。
在一些实施例中，上述分隔件50可以与阀壳10一体成型连接，使分隔件50的位置稳定，在换热介质的冲击下不会改变位置。
或者分隔件50与阀壳10的内壁焊接相连；或者，阀壳10上设置定位槽和支撑板，分隔件50定位在定位槽中，并支撑在支撑板上，相对于阀壳10的位置稳定、便于装配。
在本申请的一些实施例中，如图2和图3所示，阀壳10设有至少两个连接区域12，每个连接区域12上均设有多个流通口11，不同的连接区域12对应不同的阀芯20，每个连接区域12均可与外部装置相连接。例如，外部装置为外部管道，外部管道的接口对接在流通口11上，实现与内部阀芯20中的第一连通通道21或第二连通通道22相连通，实现换热介质在外部管道和内部阀芯20之间的流动。又例如，外部装置可以为集成式槽口，多个槽口分别与流通口11相接合，能同时实现同一个连接区域12上的多个流通口11与外部装置连通，布置方便、集成度高。
在一些实施例中，当阀壳10的表面为曲面时，连接区域12也形成为曲面；当阀壳10的表面为平面时，连接区域12也形成为平面，可根据实际情况合理选择。
在一些实施例中，如图1所示，布置在连接区域12上的流通口11可成阵列布置或成多行多列布置，也可以为随机间隔布置，可根据外部装置的安装环境、阀芯20内部所设置的第一连通通道21和/或第二连通通道22的结构进行优化。
在一些实施例中，流通口11的截面轮廓可以为圆形、方形或不规则多边形，可根据实际情况进行选择。
在本申请的一些实施例中，如图2和图3所示，第一连通通道21与第二连通通道22相分隔，也就是说，位于第一连通通道21中的换热介质不会流入到第二连通通道22中，位于第二连通通道22中的换热介质也不会流入到第一连通通道21中，使阀芯20中的换热介质的流路设计更加合理，防止不同的连通通道中的换热介质发生串流，确保各个连通通道在切换后能形成确切的通路模式，便于对多通切换阀100进行精确控制，提升多通切换阀100模式切换控制的稳定性。
在一些实施例中，第一连通通道21沿阀芯20的外周壁延伸，例如可以为沿外周壁平行于阀芯20的轴向延伸，或沿外周壁平行于阀芯20的径向延伸，或沿外周壁的与阀芯20的轴向或径向成角度延伸。进一步地，第一连通通道21可连通两个位置相近的流通口11，例如可以为相邻开设在阀壳10上的流通口11。或者，第一连通通道21可以连通两个位置较远的流通口11，例如为连接区域12对角线上的流通口11。
在一些实施例中，第一连通通道21包括内部流道和两个过口，两个过口通过内部流道连通，内部流道设在阀芯20的内部，两个过口位于阀芯20的外周壁上，充分利用阀芯20的结构开设足够多的第一连通通道21，并提升阀芯20的过流通路可选模式。
在一些实施例中，第二连通通道22根据分隔件50上的通口51以及阀壳10上的流通口11的位置而灵活设置结构，例如第二连通通道22的部分通道可以为沿阀芯20轴向延伸，第二连通通道22的部分通道可以沿阀芯20的径向延伸，第二连通通道22的部分通道可沿阀芯20的周向延伸，还可与阀芯20的转动轴201成角度延伸，这里不做具体限制，以方便连接流通口11和通口51为准。
在本申请的一些实施例中，如图2和图3所示，多通切换阀100还包括密封件30，密封件30设在阀壳10和阀芯20之间，密封件30对应多个流通口11设置相应的避让口。密封件30可对阀壳10与阀芯20之间的空间进行密封，以填充阀壳10和阀芯20之间的间隙，避免不同的第一连通通道21之间相互串流，也避免第一连通通道21和第二连通通道22发生串通。
在一些实施例中，密封件30与阀芯20相连并随阀芯20同步转动，此时的密封件30与阀芯20之间相对静止，阀芯20和密封件30均相对于阀壳10转动。例如在具体示例中，密封件30与阀芯20一体设计，减少零部件数量，方便安装。
进一步地，密封件30上的避让口与流通口11的数量一致，使第一连通通道21或第二连通通道22中的换热介质能穿过密封件30的避让口并从流通口11通入或通出。
在其他示例中，密封件30连接在阀壳10上，密封件30和阀壳10之间相对位置不变，阀芯20则可相对密封件30和阀壳10转动，方便安装密封件30，也使密封件30的避让口与流通口11能始终对应设置，不发生偏移，减少驱动机构40对阀芯20驱动所需的驱动力。
在一些实施例中，密封件30的材料为海绵、橡胶等具有一定弹性的材料，使密封件30与阀壳10、阀芯20之间具有一定压力和弹性变形应变力，提高密封性和使用寿命。
下面参考说明书附图描述本申请实施例的热管理系统1000，集成度高、安装方便且结构紧凑、便于控制。热管理系统1000主要用于进行流体分配或改变液体流向的场景中，例如可用于液压系统、空调系统和水循环系统、汽车的热管理冷却循环系统中对换热介质进行分配和流向控制。用于车辆中，主要指为电池、电机、功率器件、乘员舱之间进行换热能量分配的能量管理系统。

在一些实施例中，如图9所示，汇流板200上设有进流接头210和出流接头230，其中流道220可连通进流接头210和出流接头230，进流接头210方便与水箱之间布置管路，出流接头230方便与换热循环系统的管路进行连接，使各管路与汇流板200装配快捷、操作方便。
在一些实施例中，热管理系统1000还包括循环泵（图未示出），循环泵也集成设在汇流板200上，并连接在水箱和多通切换阀100之间，循环泵可为换热循环系统泵送换热介质，并控制换热介质的流动方向，使热管理系统1000的集成度更高。
