背景技术
随着新能源车型的普及，热管理系统在新能源汽车上的重要性和复杂度逐步提升，尤其是水路的复杂度上升较为明显，热管理系统的小型化、集成化已成为行业内的趋势。
与此同时，整车能耗、续航里程的表现也越来越受到重视，热泵系统也在逐渐普及，系统模式越来越多。目前的系统模式主要有：乘员舱制热和电池包冷却；乘员舱单独热泵加热；乘员舱和电池同时制冷；乘员舱和电池包同时制热；电机加热电池包；乘员舱和电池加热；乘员舱热泵加热；乘员舱制热和电池冷却。现有的热管理系统在实现上述功能时，每增加一个功能需要增加一个流道，相应增加一个控制该流道的阀门，所以热管理系统中通常设置有多个阀门。
然而，目前的阀门集成度较低，导致热管理系统控制复杂度和安装复杂度较高。
发明内容
本申请实施例提供一种多通阀、热管理系统和汽车，能够提高阀门集成度，降低热管理系统的控制复杂度和安装复杂度。
第一方面，本申请实施例提供一种多通阀，包括阀体和至少两个阀芯，所述阀体包括容置腔，至少两个所述阀芯转动设置在所述容置腔内。

本申请实施例提供的多通阀，通过设置多个流道，可以使多个流道中的部分流道与多个外部管路连通，通过设置至少两个阀芯，并且将至少两个阀芯转动设置在容置腔内，可以通过至少两个阀芯的转动来控制全部流道的流通与关闭，从而能够分别连通不同外部管路和不同的流道，这样可以达到一个多通阀调节多个外部管路的目的，提高了阀门的集成度，并且使热管理系统控制更简单，安装更简便，降低了热管理系统的控制复杂度和安装复杂度。
在第一方面的一种可能的实施方式中，所述流道包括内流道和外流道，所述内流道的两端均与所述容置腔连通，所述外流道的第一端与所述容置腔连通，所述外流道的第二端与所述外部管路连通。
至少一个所述阀芯沿自身的转动中心转动，并连通多个所述外部管路和不同的所述外流道。
这样通过设置内流道，可以使阀体内的不同腔体连通，从而使流体可以在不同腔体流过并且达到预定外流道，通过设置外流道，一方面可以使外部管路的流体流入阀体，另一方面可以使阀体内的流体流入预定外部管路。

所述阀芯包括第一阀芯和第二阀芯，所述第一阀芯位于所述第一容置腔内，所述第二阀芯位于所述第二容置腔内。
这样可以使第一容置腔和第二容置腔相对独立，不直接连通，将第一阀芯和第二阀芯分别设置在第一容置腔和第二容置腔内，可以避免第一阀芯和第二阀芯相互干扰，也便于第一阀芯和第二阀芯分别控制不同流道的连通和关闭。
在第一方面的一种可能的实施方式中，所述壳体上设置有多个阀口，多个所述阀口分别位于所述壳体的不同位置。
部分所述阀口和所述第一容置腔连通，其余所述阀口和所述第二容置腔连通。

这样使多通阀可以切换多种不同的连通模式，从而可以大大提高阀门的集成度，使热管理系统控制更简单，安装更简便，降低了热管理系统的控制复杂度和安装复杂度。
在第一方面的一种可能的实施方式中，所述第一阀口等间隔分布，所述阀口D和所述阀口E的中心线夹角为90°。

具体实施方式
在电动汽车领域，随着新能源车型的普及，热管理系统在新能源汽车上的重要性和复杂度逐步提升，尤其是水路的复杂度上升较为明显，热管理系统的小型化、集成化已成为行业内的趋势。与此同时，整车能耗、续航里程的表现也越来越受到重视，热泵系统也在逐渐普及，系统模式越来越多。目前的系统模式主要有：乘员舱制热和电池包冷却；乘员舱单独热泵加热；乘员舱和电池同时制冷；乘员舱和电池包同时制热；电机加热电池包；乘员舱和电池加热；乘员舱热泵加热；乘员舱制热和电池冷却。现有的热管理系统在实现上述功能时，每增加一个功能需要增加一个流道，相应增加一个控制该流道的阀门，所以热管理系统中通常设置有多个阀门。
如图1所示，在相关技术一中，该热管理系统的系统管路连接了电池包22、充电器23、驱动装置24、冷凝器25、散热器26等设备，为了将上述多种设备连接并实现对多种模式的切换，在系统管路的不同位置设置了3个三通阀21来控制不同的管路，并且每个三通阀21均为独立控制，然而这种方式存在以下缺点：多个三通阀21独立控制，需具备多个电机，且需更长的控制线束，造成成本上升；控制复杂度相对较高，整车布置空间要求高。
在相关技术二中，热管理系统中连接了电池包、驱动装置、冷凝器、散热器和冷冻机，为了将上述多种设备连接并实现对多种模式的切换，在系统管路中设置了多通阀，可以实现四种热管理模式。虽然该热管理系统中将水阀集成为1个多通阀，但是在该系统中可以实现的模式较少。
为此，为了解决上述问题中的至少一个技术问题，本申请提供一种多通阀100、热管理系统和汽车，通过在多通阀100上设置多个流道60，可以使多个流道60中的部分流道60与多个外部管路连通，通过设置至少两个阀芯40，并且将至少两个阀芯40转动设置在容置腔内，可以通过至少两个阀芯40的转动来控制全部流道60的流通与关闭，从而能够分别连通不同外部管路和不同的流道60，这样可以达到一个多通阀调节多个外部管路的目的，提高了阀门的集成度，并且使热管理系统控制更简单，安装更简便，降低了热管理系统的控制复杂度和安装复杂度。
第一方面，本申请实施例提供一种多通阀，如图2、图3和图4所示，该多通阀100包括阀体30和两个阀芯40，阀体30包括容置腔，两个阀芯40均转动设置在容置腔内，即两个阀芯40可以在容置腔内转动。阀体30上设置有多个流道60，多个流道60均与容置腔连通，且至少部分流道60与多个外部管路连通，至少一个阀芯40可以沿自身的转动中心转动，通过转动可以控制流道60的连通与关闭，从而可以在不同的转动角度下连通不同的外部管路和不同的流道60。需要说明的是多个外部管路指的是：在一个总的管路中和多通阀100连接的各分支管路。
需要说明的是，本申请实施例以圆柱形的多通阀100为例进行的说明，多通阀100也可以是球形或者其他形状，本申请实施例对多通阀100的形状不作限制，此外，本申请实施例以两个阀芯40为例进行的说明，在电机扭矩足够的前提下，可以扩展更多级的阀芯40。
这样设置多个流道60，可以使多个流道60中的部分流道60(另一部分流道60不与外部管路直接连通)与多个外部管路连通，通过设置两个阀芯40，并且将两个阀芯40转动设置在容置腔内，可以通过两个阀芯40的转动来控制全部流道60的流通与关闭，从而能够分别连通不同外部管路和不同的流道60，这样可以达到一个多通阀调节多个外部管路的目的，提高了阀门的集成度，并且使热管理系统控制更简单，安装更简便，降低了热管理系统的控制复杂度和安装复杂度。
在一种可以实现的实施方式中，流道60可以包括内流道61和外流道62，内流道61的两端均与容置腔连通，外流道62的第一端与容置腔连通，外流道62的第二端与外部管路连通，这里具体指所有的外流道62和所有的外部管路均分别连通。具体的，至少一个阀芯40沿自身的转动中心转动，并连通多个外部管路和不同的外流道62。
这样通过设置内流道61，可以使阀体30内的不同腔体411之间连通，在阀体30内部对流体的流向进行调节，从而使流体可以在不同腔体411流过并且达到预定外流道62，通过设置外流道62，一方面可以使外部管路的流体流入阀体30，另一方面可以使阀体30内的流体流出，从而流入预定外部管路。
需要说明的是，这里的第一端和第二端为外流道62的相对两端，并且“连通”指二者直接连通。
在一种可以实现的实施方式中，阀体30可以包括壳体31和顶盖32，具体的，顶盖32盖合在壳体31上，容置腔包括第一容置腔50和第二容置腔(未示出)，第一容置腔50位于壳体31内，顶盖32和壳体31的外壁共同围成第二容置腔。阀芯40具体包括第一阀芯41和第二阀芯42，第一阀芯41位于第一容置腔50内，第二阀芯42位于第二容置腔内。
这样可以使第一容置腔50和第二容置腔相对独立，不直接连通(在本实施例中，第一容置腔50和第二容置腔为间接连通)，将第一阀芯41和第二阀芯42分别设置在第一容置腔50和第二容置腔内，可以避免第一阀芯41和第二阀芯42相互干扰，使第一阀芯41和第二阀芯42可以独立工作，也便于第一阀芯41和第二阀芯42分别控制不同流道60的连通和关闭。
在一种可以实现的实施方式中，壳体31上设置有多个阀口，多个阀口分别位于壳体31的不同位置。部分阀口和第一容置腔50连通，其余阀口和第二容置腔连通。这样可以通过阀口将第一容置腔50或第二容置腔和不同流道60连通，便于流体从阀体30中流过且到达预定外部管路中。
在一种可以实现的实施方式中，如图6所示，壳体31可以包括筒体311和设置在筒体311的端部的延伸部312，具体的，第一容置腔50位于筒体311内，顶盖32盖合在延伸部312上，顶盖32和延伸部312围成第二容置腔。部分阀口设置在筒体311的侧壁上，并与第一容置腔50连通，其余阀口设置在延伸部312上，并与第二容置腔连通。
需要说明的是，本申请实施例中的“筒体”指底部封闭的筒状结构，这样通过设置延伸部312，可以使延伸部312具有分隔第一容置腔50和第二容置腔的作用，延伸部312上的阀口可以连通第一容置腔50和第二容置腔。
在一种可以实现的实施方式中，如图6所示，筒体311上的阀口包括第一阀口71和第二阀口72，第一阀口71靠近延伸部312设置，第二阀口72远离延伸部312设置。第一阀口71和第二阀口72在筒体311的周向上间隔设置，且在筒体311的延伸方向上，第一阀口71和第二阀口72一一对应。这样可以使筒体311上的阀口排列比较规整，一方面便于加工制造，另一方面便于设置外流道62和内流道61。
需要说明的是，筒体311的延伸方向指竖直方向或筒体311的高度方向，在本申请实施例中，在筒体311的高度方向上，将位于同一高度且靠近延伸部312的一排阀口统称为第一阀口71，将位于同一高度且远离延伸部312的一排阀口统称为第二阀口72。
在一种可以实现的实施方式中，在筒体311的周向上，第一阀口71包括：沿逆时针依次间隔排布的阀口D、阀口B、阀口2、阀口A、阀口X、阀口8、阀口C、阀口9、阀口c和阀口E。第二阀口72包括：沿逆时针依次间隔排布的阀口d、阀口3、阀口10、阀口4、阀口a、阀口1、阀口b、阀口7、阀口5和阀口e。延伸部312上的阀口包括阀口6和阀口11。阀口的布置方式可以参照图7所示，图中的中心线表示阀口在筒体311周向的设置位置，靠近筒体311的一圈数字和字母代表第一阀口71，远离筒体311的一圈数字和字母代表第二阀口72。
需要说明的是，在附图中并未将所有的内流道61画出，内流道61的设置方式可以参照如下方式：内流道61包括第一内流道(未示出)、第二内流道(未示出)、第三内流道(未示出)、第四内流道(未示出)、第五内流道(未示出)、第六内流道(未示出)和第七内流道(未示出)。第一内流道的两端分别连接阀口A和阀口a。第二内流道的两端分别连接阀口B和阀口b。第三内流道的两端分别连接阀口C和阀口c。第四内流道的两端分别连接阀口D和阀口d。第五内流道的两端分别连接阀口E和阀口e。第六内流道的两端分别连接阀口X和阀口6，第七内流道的两端分别连接阀口X和阀口11，第六内流道和第七内流道连通。这里需要说明的是，第六内流道和第七内流道可以将第一容置腔50和第二容置腔间接连通。
具体的，阀口1、阀口2、阀口3、阀口4、阀口5、阀口6、阀口7、阀口8、阀口9、阀口10和阀口11分别通过多个外流道62和多个外部管路一一对应连通。
上述设置方式可以使多通阀100切换多种不同的连通模式，从而可以大大提高阀门的集成度，使热管理系统控制更简单，安装更简便，降低了热管理系统的控制复杂度和安装复杂度。
在一种可以实现的实施方式中，如图7所示，第一阀口71等间隔分布，具体的，第一阀口71中的相邻阀口之间的夹角相等，可以为30°，这样沿逆时针排布后，阀口D和阀口E的中心线夹角为90°。
需要说明的是，第一阀口71和第二阀口72在筒体311的竖直方向上一一对应设置，第二阀口72中的相邻阀口的角度与第一阀口71中的相邻阀口的角度相同，因此这里只强调了第一阀口71的设置方式。这样，一方面有利于在电机的扭矩有限的情况下，可以实现控制多个阀口的目的，另一方面也为未来增加更多阀口预留了设置空间。
在一种可以实现的实施方式中，如图8所示，第一阀芯41可以包括多个腔体411，多个腔体411沿第一阀芯41的周向均匀排布。第一阀芯41可以包括多个第一隔板412和多个第二隔板413，第一隔板412和第二隔板413分别位于不同的腔体411内。具体的，第一隔板 412分隔腔体411为两个第一子腔体4111；第二隔板413分隔腔体411为两个第二子腔体4112。第一隔板412和第二隔板413可以相互垂直，例如可以是竖直隔板和水平隔板。
这样使第一阀芯41在转动不同角度的情况下，可以使不同的第一子腔体4111或第二子腔体4112将不同的外流道62或内流道61连通或关闭，从而达到控制多个流道60的目的，提高了阀门的集成度。
在一种可以实现的实施方式中，如图9所示，延伸部312上设置有第一限位块3121和第二限位块3122，第二阀芯42位于第一限位块3121和第二限位块3122之间。这样可以使第二阀芯42在固定角度范围内旋转，从而达到控制阀口6和阀口11的目的。
在一种可以实现的实施方式中，如图12所示，第二阀芯42包括连接部421和封挡部422，连接部421位于第一限位块3121和第二限位块3122之间，封挡部422上设置有通孔423，通孔423可以和阀口6或阀口11连通。
具体的，如图10所示，第二阀芯42转动，封挡部422封挡阀口6，连接部421抵接第一限位块3121，通孔423与阀口11连通。如图11所示，第二阀芯42转动，封挡部422封挡阀口11，连接部421抵接第二限位块3122，通孔423与阀口6连通。这样可以在封挡其中一个阀口时，使另一个阀口连通，从而对不同外流道62(特指与第二容置腔连通的外流道62)进行关闭与连通控制。
在一种可以实现的实施方式中，如图10和图11所示，第一阀芯41上设置有第三限位块414，第一阀芯41首先逆时针转动，当第三限位块414抵接第二阀芯42的连接部421后，第一阀芯41带动第二阀芯42逆时针转动，当第二阀芯42抵接第一限位块3121后，阀口11连通，第二阀芯42停止转动。然后第一阀芯41可以顺时针转动，当第三限位块414抵接第二阀芯42的连接部421后，第一阀芯41带动第二阀芯42顺时针转动，当第二阀芯42抵接第二限位块3122后，阀口6连通，第二阀芯42停止转动。
在上述的转动过程中，第一阀芯41和第二阀芯42的转动中心位于同一条直线上。这样可以使第一阀芯41在第三限位块414抵接第二阀芯42后带动第二阀芯42转动，从而达到对不同外流道62(特指与第二容置腔连通的外流道62)进行关闭与连通控制。
在一种可以实现的实施方式中，如图5所示，阀体30上设置有转动轴80，第一阀芯41和第二阀芯42均同轴连接在转动轴80上，第一阀芯41和第二阀芯42的转动中心均位于转动轴80上。这样可以便于第一阀芯41和第二阀芯42绕转动轴80转动。
在一种可以实现的实施方式中，多通阀100还包括驱动件(未示出)，驱动件与转动轴80连接，驱动件带动第一阀芯41绕转动轴80转动。驱动件可以为电机，这样可以通过电机对多通阀100实现自动控制和精确控制。
需要说明的是，在本申请实施例中，虽然第二阀芯42也连接在转动轴80上，但是驱动件只带动第一阀芯41转动，第二阀芯42的转动通过第一阀芯41的推动来实现。
如图13所示，本申请实施例还提供了该多通阀100的旋转逻辑图，从图中可知，多通阀100开始工作后，首先进行系统模式信号输入，第二阀芯42可以旋转0°，0°对应非余热回收模式，此时阀口11打开，阀口X与阀口11连通，在该模式下第一阀芯41旋转0°，如图14所示，此时可以实现模式1：阀口2和阀口1连通，阀口4和阀口11连通，阀口5和阀口8连通，阀口3和阀口10连通，阀口7和阀口9连通；当第一阀芯41旋转120°，如图15所示，此时可以实现模式2：阀口2和阀口1连通，阀口4和阀口11连通，阀口9和阀口8连通，阀口3和阀口10连通，阀口7和阀口5连通；当第一阀芯41旋转150°，如图16所示，此时可以实现模式3：阀口3和阀口7连通，阀口11和阀口2连通，阀口9和阀口5连通，阀口10和阀口4连通，阀口1和阀口8连通； 当第一阀芯41旋转180°，如图17所示，此时可以实现模式4：阀口3和阀口9连通，阀口11和阀口4连通，阀口2和阀口10连通，阀口8和阀口1连通，阀口7和阀口5连通。
此外，第二阀芯42可以旋转-45°，-45°对应余热回收模式，此时阀口6打开，阀口X与阀口6连通，在该模式下第一阀芯41旋转-150°，如图18所示，此时可以实现模式5：阀口3和阀口5连通，阀口2和阀口10连通，阀口4和阀口1连通，阀口8和阀口6连通，阀口9和阀口7连通；当第一阀芯41旋转-180°，如图19所示，此时可以实现模式6：阀口3和阀口9连通，阀口2和阀口10连通，阀口6和阀口4连通，阀口8和阀口1连通，阀口7和阀口5连通；当第一阀芯41旋转-240°，如图20所示，此时可以实现模式7：阀口2和阀口1连通，阀口3和阀口10连通，阀口4和阀口6连通，阀口8和阀口9连通，阀口7和阀口5连通；当第一阀芯41旋转-360°，如图21所示，此时可以实现模式8：阀口2和阀口1连通，阀口3和阀口10连通，阀口4和阀口6连通，阀口8和阀口5连通，阀口9和阀口7连通。图中N和S分别表示不同旋转方向，其中N旋转方向的角度为正，S旋转方向的角度为负。
本申请实施例将多个阀门集成，使热管理系统中阀门的重量和体积占比显著减少，便于整车布置，该多通阀100为单驱动控制，仅需一路信号控制，降低了硬件成本，简化了控制逻辑，提高了热管理系统的集成性，给后续热管理系统向小型化、集成化、轻量化的演进提供了可能。
需要说明的是，本申请实施例中的多通阀100不仅可以应用于热管理系统中，也可以应用于任何需要多模式的液冷循环回路中。
第二方面，本申请实施例提供了一种热管理系统，该热管理系统包括上述的多通阀100和多个外部管路，多通阀100的多个外流道62分别和多个外部管路连通，外部管路上可以连接多个设备，图22为具体的热管理系统图，在该热管理系统中，外部管路上可以设置蒸发器19’、电池包22’、冷凝器25’、散热器26’、热交换器28’和动力总成27’等，其中，蒸发器19’的两端分别和多通阀100的阀口3和阀口2连通，电池包22’的两端分别和多通阀100的阀口8和阀口9连通，冷凝器25’的两端分别和多通阀100的阀口4和阀口5连通，散热器26’的两端分别和多通阀100的阀口11和阀口6连通，热交换器28’的两端分别和多通阀100的阀口10和阀口1连通，动力总成27’的两端分别和多通阀100的阀口6和阀口7连通。
