具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
在本公开中，在未作相反说明的情况下，方位词“内、外”是指相关零部件的内、外。此外，术语“第一”、“第二”、等仅用于区分描述，而不能理解为指示或暗示相对重要性。另外，在本公开的描述中，还需要说明的是，除非另有明确的规定和限定，出现的术语“设置”、“相连”、“安装”应做广义理解，例如，可以是固定相连，也可以是可拆卸相连，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
本公开提供了一种阀组集成模块，该阀组集成模块能够用于实现多种预设热管理模式中的至少一种。这里的预设热管理模式包括但不限于空调制冷模式、热泵采暖模式、电池冷却模式、空调制冷和电池冷却双开模式、除湿模式登。这些热管理模式的具体工作原理将在之后做详细的描述。
为实现上述列举的多种预设热管理模式，其中的热管理***包括外部换热组件和本公开提供的阀组集成模块，换热组件包括压缩机2、车内冷凝器3、车内蒸发器5、车外换热器4、PTC风加热器7、鼓风机8、PTC水加热器9 中的多个。
如图1至图9所示，本公开提供的阀组集成模块，包括本体11、第一电动阀13和第二电动阀16，其中，本体11设置有多个内部流道以及多个用于连通内部流道和热管理***的换热组件的多个接口。在图示的实施方式中，本体11被构造为块状，以便于在其中设置内部流道。需要指出的是，本公开并不限制本体11的构造，只要能够实现在其中设置内部流道的目的即可。
第一电动阀13和第二电动阀16均设置在本体11上，且与内部流道连通。第一电动阀13和第二电动阀16均配置成能够在通断位置和节流位置之间切换。首先需要说明的是，第一电动阀13和第二电动阀16各自指的是一个阀体，该阀体根据需要能够在通断和节流降压两种功能之间切换，或者也可以说，既能够作为电磁阀使用又能够作为膨胀阀使用。
第一电动阀13和第二电动阀16可以使用任意能够实现在通断和节流降压两种功能之间切换的电动阀。以第一电动阀13为例，如图3所述，第一电动阀13可以包括球形的阀芯1305、调节座1307和执行电机1301，其中，阀芯1305设置有相互沟通且用于与内部流道相连通的第一通道和第二通道；调节座1307用于将阀芯1305维持的本体11内，例如，调节座1307上设置有外螺纹，本体11上设置有用于与外螺纹配合的内螺纹；执行电机1301用于驱动阀芯1305转动，随着阀芯1305的转动，以实现第一电动阀13在通断和节流降压两种功能之间切换的功能。进一步地，第一电动阀13沿安装方向的两端还分别设置有环形的密封块1304，以封闭接口。执行电机1301通过螺钉1301安装在本体11上。第二电动阀13可以与第一电动阀16具有相同的构造，此处不再赘述。
在本公开中，第一电动阀13的第一端与车内冷凝器出口接口11004连通，第一电动阀13的第二端与车外换热器进口接口11005连通；第二电动阀16的第一端与车外换热器出口接口11002连通，第二电动阀16的第二端选择性地与车内蒸发器进口接口11001或气液分离器进口接口11003连通。这里的 连通既可以是通断也可以是节流。
通过上述方案，即，本公开设计了一种具有多个内部通道的阀组集成模块，该阀组集成模块能够通过设置在本体上的不同接口将内部流道与外部热管理***的换热组件连通，以形成多个不同的热管理回路，并通过集成在模块上的第一电动阀和第二电动阀控制热管理回路的通断或节流，达到实现多种预设热管理模式的目的。通过上述技术方案设计的阀组集成模块，能够在实现多种热管理模式的同时，减少阀类控制部件的使用和简化热管理***的管路的连接，降低整车的重量，并能够降低成本和油耗，节省整车布置的空间。
内部流道可以通过多种方式进行设计。根据本公开的一种实施方式，内部流道可以包括内置流道和外置流道。需要注意的是，流道的内置和外置是相对于本体11的内部和外部来说的，即，内置流道和外置流道均设置在本体11上，而并非是指热管理***中的连接管路。本体11包括第一分体1101和第二分体1102，第一分体1101具有第一连接面，第二分体具有第二连接面，第一连接面和第二连接面用于密封连接，即，第一连接面和第二连接面用于相互对合。内置流道设置在第一分体1102的内部。第一分体1101的第一连接面上设置有至少一个凹槽，第一连接面上的凹槽与第二连接面能够共同限定出外置流道。
在图4至图9中示出为具有三条外置流道和一条内置流道的实施方式，其中，第二电动阀16的进口11-101与电子膨胀阀14的进口11-102连通以形成为第一外置流道11-1；将第二电动阀16的出口11-203、电池包换热器出口接口1501、车内蒸发器出口接口11006、PT传感器低压接口11-202气液分离器进口接口11002相连通以形成第一内置流道11-2；将第一电动阀13的出口11-301与车外换热器的进口接口11005相连通以形第二内置流道11-3；将电子膨胀阀14的出口11-401与电池包换热器15的进口1502相连通以形成第三内置流道11-4。应当理解的是，上述内部流道的设置为一种示例性说明，在 不会产生干涉的前提下，其他任意可行的内部流道布置方式也能够应用于本公开中，此处不做限定。此外需要指出的是，当部分实施方式不具有相应的换热组件，例如，电池包换热器15或PT低压传感器12的时候可以略去相对应的内部流道。进一步地，用于形成外置流道的凹槽的截面可以呈U形，并且凹槽的截面面积大于第一电动阀13和第二电动阀16的阀口面积的10％，以使得冷媒能够顺畅的从第一电动阀13和第二电动阀16的阀口流入到外置流道中。此外，连通车内蒸发器出口接口11006和气液分离器进口接口11003之间的内部流道可以构造为直线型流道，以能够降低冷媒的流动阻力。当阀组集成模块设置有PT传感器12时，PT低压传感器12可以设置在车内蒸发器出口接口11006和气液分离器进口接口11003之间。当车内蒸发器出口接口11006和气液分离器进口接口11003之间的内部流道构造为直线型流道时，还能够提高PT传感器12测量的精确性。
根据本公开的一种实施方式，如图1至图3所示，阀组集成模块还可以包括设置在本体11上的电子膨胀阀14，电子膨胀阀14的第一端与车外换热器出口接口11002连通，第二电子膨胀阀14的第二端与设置于本体11上的电池包换热器进口接口连通。电子膨胀阀14可以包括用于***到本体11中的插接部1401，电子膨胀阀14和块本体11通过穿设于块本体11的尾端带螺纹的销钉1402固定连接。
阀组集成模块还可以包括设置在本体11上的电池包换热器15，电池包换热器15可以通过螺钉1107与本体11连接。电池包换热器15的进口与电池包换热器进口接口连通，电池包换热器15的出口连接至气液分离器。作为一种用于安装电池包换热器15的方式，在本体11上分别设置有用于与电池包换热器15的第一端和第二端连接的连接接头1103、1105，以及用于密封电池包换热器15的第一端和第二端的O型圈1104、1106，电池包换热器15与本体11通过螺纹紧固件连接。
通过上述技术方案还能够进一步实现电池包冷却的热管理模式。此外， 在本公开中，如图2所示，电子膨胀阀14的装配位置和车外换热器出口接口11002位于本体11同一侧，以便于第二电动阀16与电子膨胀阀14共用同一进口11002，并保障连接电子膨胀阀14的进口11-102的流道较短，不形成拐弯角度，达到低流阻设计。
