如图1至图35所示，流体控制组件1包括连接体10和阀芯20，流体控制组件1具有容纳腔101和连通口102，连通口102邻近容纳腔101且与容纳腔101连通，连接体10包括侧壁部11，侧壁部11形成容纳腔101的至少部分周壁，连通口102位于侧壁部11，连接体10还可以包括顶壁部以及底盖12，侧壁部11、顶壁部以及底盖12限定容纳腔101，侧壁部11的至少部分位于顶壁部以及底盖12之间，顶壁部以及底盖12的其中一者可以与侧壁部11一体注塑成型为一体结构，另一者与侧壁部11密封连接，阀芯20的至少部分位于容纳腔101且阀芯20能够在带动下转动。可选地，流体控制组件1还包括驱动组件50，驱动组件50包括驱动件，驱动件可以包括电机或者电机与传动齿轮组的组合，驱动件与阀芯20传动连接，以使驱动件带动阀芯20转动。

进一步地，流体控制组件1还可以包括第二流道板42，第二流道板42与第一流道板41密封设置且形成流道43的壁部，此时第一流道板41和第二流道板42围合形成流道43。可选地，第二流道板42可以与第一流道板41焊接设置，流体控制组件1还具有与流道43连通的安装接口44，安装接口44位于第一流道板41和第二流道板42的其中一者，安装接口44能够与流体管理组件的端口连通。其中，流体管理组件可以但不限于为换热器、水泵、储液器的其中一者或组合，通过上述设置，使得流体管理组件便于与流体控制组件1连通，能够减少流体管理组件和流体控制组件1之间的管路。
进一步参阅图1至图22，图中示出本申请一种实施例提供的流体控制组件1，在本实施例中，流体控制组件1还包括第一密封件30，沿容纳腔101的径向，第一密封件30的至少部分位于侧壁部11和阀芯20之间，用于对流体控制组件1实现密封。第一密封件30包括与连通口102对应连通的孔道31，可选地，第一密封件30包括与连通口102数量相同且一一对应连通的孔道31，如图9至图12所示，沿第一密封件30的轴向，第一密封件30的全部数量的孔道31的正投影沿阀芯20的圆周方向间隔排布，孔道31包括第一孔道32和第二孔道33，第一孔道32和第二孔道33沿第一密封件30的轴向间隔排布，具体地如图10所示，第一孔道32位于第一密封件30的其中一高度，第二孔道33位于第一密封件30的另一高度，沿第一密封件30的轴向，第一孔道32的正投影和第二孔道33的正投影沿阀芯20的圆周方向间隔排布，此时，沿阀芯20的圆周方向间隔排布的第一孔道32和第二孔道33分别位于第一密封件30的不同高度，相较于将所有孔道沿阀芯的圆周方向间隔排布且将所有孔道设置于密封件的同一高度而言，本申请实施例提供的流通控制装置的第一密封件30能够便于增加位于同一高度位置处的两个孔道31之间的壁部的距离，便于使阀芯20在旋转时压紧第一密封件30的壁部，这样便于提高流体控制组件的密封性能。
为防止第一密封件30转动，第一密封件30包括第一配合部34，连接体包括限位部14，第一配合部34与限位部14限位连接，例如，第一配合部34可以为孔结构和凸起结构的其中一者，限位部14可以为孔结构和凸起结构的另一者，凸起结构嵌入孔结构内进行限位。
为实现连通口102和孔道31的对应连通，如图3至图8所示，在一些实施例中，沿侧壁部11的轴向，连通口102的正投影沿阀芯20的圆周方向间隔排布，连通口102包括第一连通口1021和第二连通口1022，第一连通口1021和第二连通口1022沿侧壁部11的轴向间隔排布，第一连通口1021与第一孔道32对应连通，第二连通口1022与第二孔道33对应连通。可选地，连通口102可以包括三个第一连通口1021和两个第二连通口1022，三个第一连通口1021可以位于流体控制组件1的同一高度，两个第二连通口1022可以位于流体控制组件的同一高度，沿侧壁部11的轴向，三个第一连通口1021的正投影邻近设置，两个第二连通口1022的正投影邻近设置。其中，本文中各连通口的沿阀芯20的轴向的正投影包括各连通口的壁部沿阀芯20轴向的正投影所围合限定的区域，侧壁部11的轴向、阀芯20的轴向以及第一密封件30的轴向平行或重合。
如图9至图12所示，第一密封件30的孔道31包括至少一个第一孔道32和至少两个第二孔道33，沿第一密封件30的轴向，全部数量的第一孔道32的正投影邻近设置，全部数量的第二孔道33的正投影邻近设置。在具体实施时，第一密封件30的孔道31包括至三个第一孔道32和两个第二孔道33，三个第一孔道32可以位于第一密封件30的同一高度，两个第二孔道33可以位于第一密封件30的同一高度，沿第一密封件30的轴向，三个第一孔道32的正投影邻近设置，两个第二孔道33的正投影邻近设置，在本实施方式，相邻两个第一孔道32之间的角度可以为90度，相邻两个第二孔道33之间的角度可以为45度。
进一步参阅图9至图12，定义三个第一孔道32分别为第一子孔道321、第二子孔道322和第三子孔道323，定义两个第二孔道33分别为第四子孔道331和第五子孔道332，第一密封件30包括第一圆周壁部35和第二圆周壁部36，沿第一密封件30的轴向，第一圆周壁部35的正投影和第二圆 周壁部36的正投影沿阀芯20的圆周方向排布，第一圆周壁部35位于第一子孔道321和第三子孔道323之间，第一圆周壁部35与第二子孔道322分设于第一密封件30径向的两侧，第一圆周壁部35对应的圆心角a1大于90度且小于180度，第二圆周壁部36位于第四子孔道331和第五子孔道332之间，第二圆周壁部36对应的圆心角a2大于180度。此时，在第一密封件30的第一孔道32所在的高度，有几乎一半的壁部没有设置孔道，在第一密封件30的第二孔道33所在的高度，有几乎大于一半的壁部没有设置孔道，相较于将全部数量的孔道圆周排布于密封件的同一高度而言，本申请实施例提供的流体控制组件能够增加位于同一高度位置处的两个孔道31之间的壁部的距离，便于提高流体控制组件的密封性能。
当阀芯20在转动时，由于驱动组件50的控制精度或者信号传递延时或者阀芯部件20的转动惯量等因素影响，阀芯20可能会转动至设定角度之前停止或者超过设定角度后继续旋转，易使阀芯20产生转动公差，例如，阀芯部件20的转动公差角度可以为±5度，即阀芯20可能会转动至设定角度之前5度停止或者超过设定角度后继续旋转5度停止，因此，为了使第一密封件30能够在阀芯部件20转动的各个行程范围内均与阀芯部件20接触，使第一密封件30具有较好的密封性能，在本实施例中，通过设置第一孔道32和第二孔道33沿第一密封件30的轴向间隔排布，能够增加位于同一高度位置处的两个孔道31之间的壁部的距离，便于使阀芯20在行程范围内均与第一密封件30的壁部接触，便于提高第一密封件30的密封性能。
如图14至图18所示，在一些实施例中，阀芯20包括第一腔组21、分隔板23以及第二腔组22，沿阀芯20的轴向，分隔板23位于第一腔组21和第二腔组22之间，第一腔组21具有至少两个相互隔离的第一导通腔211，第二腔组22具有至少两个相互隔离的第二导通腔221，分隔板23具有通孔231，部分数量的第一导通腔211和部分数量的第二导通腔221通过通孔231对应连通，旋转阀芯20能够通过第一导通腔211、通孔231以及第二导通腔221使第一孔道32和第二孔道33对应的连通口102导通。通过上述设置，能够实现流体控制组件对流体的控制功能。
结合图3至图22所示，流体控制组件的连通口102包括第一口P1、第二口P2、第三口P3、第四口P4和第五口P5，第一口P1的正投影、第二口P2的正投影、第三口P3的正投影、第四口P4的正投影和第五口P5的正投影沿阀芯20的圆周方向间隔且顺次排布，附图中以上述五个口的正投影沿沿阀芯20的圆周方向逆时针排布为例进行说明，可选地，第一口P1的正投影、第二口P2的正投影、第三口P3的正投影、第四口P4的正投影和第五口P5的正投影沿阀芯20的圆周方向顺时针排布。沿侧壁部11的轴向，第一口P1、第二口P2和第三口P3位于流体控制组件1的其中一高度，第四口P4和第五口P5位于流体控制组件1的另一高度，其中，第一口P1与第一子孔道321导通，第二口P2与第二子孔道322导通，第三口与第三子孔道323导通，第一口P1和第三口P3的其中一者与第二口P2能够通过第一导通腔211导通，第四口P4和第五口P5的其中一者与第一口P1能够通过第一导通腔211、通孔231、第二导通腔221、对应的第一孔道32和对应的第二孔道33导通，第四口P4和第五口P5的其中一者与第三口P3能够通过第一导通腔211、通孔231、第二导通腔221、对应的第一孔道32和对应的第二孔道33导通。通过上述设置，能够实现流体控制组件的多种流通方式。在具体实施时，流体控制组件的连通口102的数量可以为三个、四个、五个、六个或者更多数量，本申请对此不进行限定。
