下述各实施例的多通路阀可应用于车辆的热管理系统中，尤其是适用于电动车辆的热管理系统中。
请结合参阅图1至图17，本发明提供的多通路阀组件，包括具有内腔的壳体组件200和可回转的设置在内腔中的阀体100，内腔中设有底面211，该底面211上设置有多个端口，阀 体100上设置有至少两条互不连通的流道(参见标号101～105)，各流道均为轨迹处于阀体100的端面上的平面型流道，每条流道用于连通至少两个端口；此处及下述各实施例中，将设置各流道的端面定义为第一端面110，第一端面110始终紧贴在底面211上，且阀体100相对壳体组件200具有至少两个转动档位，当转动阀体100切换转动档位时，与各流道连接的端口被切换。此处的端口为用于供壳体210外的管路接入相应流道的端口。
为便于理解转动阀体100切换转动档位的过程中，分别参见图5至图8对应的多通路阀组件、图9至图11的多通路阀组件、图12至图15的多通路阀组件、图16和图17，各附图中，端口的截面形状为圆形，各端口的标号各自对应相应的数字序号，如数字需要1、2、3…8，在实际实施过程中，端口的截面没有限制，只要能够供流体介质通过即可，端口的数量也不限于8个，而是根据需求进行设置；各附图中，各流道的标号各自对应相应的标号，如标号101、102、103、104、105，在热管理过程中，手动或自动转动将阀体100按特定角度转动即可切换转动档位，使各流道连接的端口被切换，例如，图1至图15的各附图中，切换的转动角度为60度的倍数，在实际实施过程中，切换角度根据端口和流道的布置方式确定，而并不限于60度的倍数。
本发明的多通路阀组件中，流道为设置在阀体端面的平面型流道，使得流道的加工更简单、加工成本更低；并且端口也设置在壳体的相应端面，相较将端口设置在壳体组件侧壁的方式，不仅能使得整个多通路阀占用的空间更小，还能使得该端口与热管理系统中各管路的管接头连接后，整个连接结构所占用的空间进一步缩小。
图16中，各流道采用直线型流道、折线型流道，图9至图11中，各流道均采用等曲率的圆弧流道，在实际实施过程中，参见图5至17，流道的种类可以包括直线型流道、折线型流道、等曲率圆弧流道、变曲率圆弧流道、直线圆弧组合型流道、折线圆弧组合型流道中的一种或至少两种。
在一些实施例中，参见图5至图17，每条流道具有至少两处用于与端口连接的接入点，且每处接入点与至少一个端口具有相等的回转半径。例如，图5至图8中的流道101具有3个接入点，这3个接入点即为图3中标注的接入点A、B、C。
在一些实施例中，按回转半径分组，各端口至少分为两组端口组，单组端口组的各端口具有相同的回转半径，例如，图5至图17中，均设置两组端口组，即第一端口组和第二端口组，第一端口组对应第一端口1、第二端口2、第三端口3和第四端口4，第二端口组对应第 五端口5、第六端口6和第七端口7。当然，在实际实施过程中，也可以只设置一组端口组，但设置两组或两组以上的端口组有利于形成更多档位。此处的组端口组中，单个端口组可以只设置一个端口，也可以包括两个或两个以上的端口，例如，图18中，设置三组端口组，第一组端口组中只有第一端口1、第二组端口组包含第二端口2、第三端口3、第四端口4，第三组端口组包含第五端口5、第六端口6、第七端口7和第八端口8。
为便于理解，下述各实施例中，参见图5、图9、图16，将第一端面110分为中心封闭区域m和至少一个环形封闭区域n，中心封闭区域m及各环形封闭区域由内至外依次设置，中心封闭区域具有虚拟外轮廓(详见各附图中的虚线轮廓)，每个环形封闭区域均具有虚拟内轮廓和虚拟外轮廓(图未示)。其中，虚拟外轮廓和虚拟内轮廓并非真正的轮廓，只是为了便于理解各流道组件的分布方式，另外，此处的环形封闭也并非是指代两个圆圈围城的区域，虚拟外轮廓和虚拟内轮廓的具体轮廓没有限制，只要满足单个环形封闭区域的虚拟外轮廓围在虚拟内轮廓外即可。
在一些实施例中，第一端面上设置有至少两组流道组件，且一组流道组件对应处于其中一个封闭区域内，每组流道组件对应一组所述端口组件，每组流道组件均包括至少两条流道，且在相对应的流道组件和端口组中，各端口的回转半径与各所述接入点的回转半径相等。
具体的，例如，图5至图8中，第一端面110上设置有第一流道组件(包括流道101、102、103)和第二流道组件(104、105)，第一流道组件的各流道处于中心封闭区域m内，第二流道组件的各流道组件处于环形封闭区域n内，第一流道组件的各接入点的回转半径相等，第二流道组件的各接入点的回转半径相等，第一流道组件对应的端口组中各端口的标号为标号1、2、3、4，第二流道组件对应端口组中各端口的标号为5、6、7、8。
当然，在实际实施过程中，参见图12、图17，第一端面110上也可以设置有跨区域流道，跨区域流道中至少有两个回转半径互不相等的接入点，也就是说第一端面110的各流道都的设置区域并不按照上述的中心封闭区域和环形区域的方式对应进行分组，跨区域流道的各接入点至少分布在两个封闭区域，例如，图12中，流道101共有三个接入点，其中两个接入点分布在标号m为的中心封闭区域，一个接入点分布在标号为n的环形封闭区域，图17中，流道101也有三个接入点，其中一个接入点分布在标号m为的环形封闭区域，两个接入点分布在标号为n的环形封闭区域，
在一些实施例中，结合参见图3、图5至图8，中心封闭区域m内的流道组件包括第一 流道101、第二流道102和第三流道103，第一流道101具有第一接入点A、第二接入点B和第三接入点C，第二流道102具有第四接入点D、第五接入点E，第三流道103具有第六接入点F、第七接入点G和第八接入点H，第二流道102隔在所述第一流道101和第三流道103之间，使所述第一接入点A、第二接入点B、第三接入点C、第四接入点D、第六接入点F、第七接入点G、第八接入点H和第五接入点E沿周向方向依次均布设置，且各组端口组中，回转半径最小的端口组具有四个沿周向均布的端口。
在一些实施例中，其中至少一环形封闭区域内设置的流道组件为外流道组件，参见3、图5至图8，设置了一组外流流道组件，该外流道组件包括第四流道104和第五流道105，第四流道104和第五流道105为各处回转半径相等的等曲率圆弧流道，若该组流道组件对应的回转半径为R，该第四流道和第五流道的弧长均大于与该回转半径对应的周长的四分之一，且与外流道组件对应的端口组也具有四个沿轴向均布的端口。
采用这种结构的多通路阀组件具有四个档位：当处于图5所示的状态时，第二端口2和第四端口4接通、第五端口5和第八端口8接通，第六端口6和第七端口7接通；当处于图6所示的状态时，第一端口1和第三端口3接通、第七端口7和第八端口8接通、第五端口5和第六端口6接通；当处于图7所示的状态时，第一端口1和第二端口2连通，第三端口3和第四端口4连通，第五端口5和第六端口6连通，第七端口7和第八端口8连通；当处于图8所示的状态时，第一端口1和第四端口4连通，第二端口2和第三端口3连通，第五端口5和第八端口8接通，第七端口7和第六端口6接通。
在实际实施过程中，参见图9至11，中心封闭区域m内的流道组件也可以不设置第二流道102，而是仅设置第一流道101和第三流道103，此时，共有三种档位，也能通过转动档位的切换实现端口与端口之间连接状态的切换，但设置该第二流道102，能够在体积不变的情况下形成更多档位。当然，在实际实施过程中，若采用图12至图15中这种具有跨区域流道的多通路阀门组件也能达到四个档位，但由于其流道跨越了区域，流道轨迹无法全部采用简单的等曲率弧线、直线，要实现其加工，虽然比现有多通路阀中流道的加工方式更简单，但其采用的设备比图5至图8所示的流道加工所需的设备要求更。
另外，在实际实施过程中，第二流道102最好采用直线型流道，第一流道101和第三流道103对称布置在第二流道102的两侧，第四流道104和第五流道105关于阀体的轴心中心对应，有利于使阀体的静平衡和动平衡能力，也就有利于避免流道因阀体偏移而发生渗漏。
在一些实施例中，壳体组件200内设置有弹性压紧件300，弹性压紧件300用于将阀体100压紧在内腔中，使第一端面110被压紧在底面211上，设置该弹性压紧件300有利于防止切换过程中流道脱离底面211而引起泄露的情况发生，提高了多通路阀组件工作时的可靠性。
具体的，在一些实施例中，该弹性压紧件300采用盘状结构，有利于均匀的压紧阀体100，减少流道内介质发生泄露的可能性。
在一些实施例中，壳体组件200包括具有开口的壳体210和可拆卸的安装在开口处的端盖220，该开口用于供阀体100沿轴向方向装入内腔中，装入阀体100时，阀体100朝向壳体210的底面211装入，然后再装入弹性压紧件300，最后安装端盖220即可。
相应的，本发明还提供一种多通路阀总成，包括电机和上述任一种所述的多通路阀组件，该驱动件400用于带动阀体100在壳体组件200的内腔中回转。其中，该驱动件400可以为电机。
在一些实施例中，参见图，驱动件400设置于阀体100上背对第一端面110的一侧，也就使得驱动件400处于阀体100的一端，而各端口以及使用状态下与各端口连接的管接头处于阀体100的另一端，驱动件400和各管接头均有足够的安装空间，整个多通路阀组件的外径尺寸可以控制在相对较小的尺寸范围内。
为了实现驱动件400带动阀体100回转，驱动件400与阀体100之间设置有传扭结构，例如，图中，阀体100上设置有凸台，该凸台依次贯穿该弹性压紧件300和该端盖220，该凸台上开设有用于供电机的输出轴配合插入的安装孔，该输出轴具有方轴段，该方轴段配合插入该安装孔中实现传钮，在实际实施过程中，这种传钮结构占用的空间小，在实际实施过程中，若输出轴和安装孔的尺寸较大，则可以通过键连接的方式实现传扭。
相应的，本发明还提供一种热管理系统，其用于管理各对象的温度，其包括至少一个加热元件、至少一个冷却元件，该热管理系统还包括上述任一种多通路阀组件，各加热元件、冷却元件和各对象各自与相应的端口连接，使得切换该多通阀组件时，各对象(被管理对象)被切换至与相应的加热元件或冷却元件连接，或被切换至与各加热元件、冷却元件均断开连 接的状态。
综上所述，本发明中，流道的加工更简单、加工成本更低，且整个多通路阀占用的空间更小。所以，本发明有效克服了现有技术中的一些实际问题从而有很高的利用价值和使用意义。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
