第一组件3位于第一主通道112内，第一主通道112包括第一流道113和第二流道114，至少部分第一组件3与第一管11的内壁面固定连接。

在一些实施例中，如图4所示，第一组件3还包括第三连接件34，第三连接件34沿第一管11的长度方向延伸。第三连接件34在第一管11的长度方向上的一端(如图4中第三连接件34的左端)与第一第一件311的第二端有间隙，第三连接件34在第一管11长度方向上的另一端(如图4中第三连接件34的右端)与第二第一件312的第二端相连。围成第二子流道1142的周壁包括第一第一件311、第二第一件312、连接第一第一件311的第一端和第二第一件312的第一端的第一连接件32、第三连接件34和第一管11的内壁，第二子流道1142与第二孔道1141连通，

如图7和图8所示，在再一些可选地实施例中，第一子流道1132与两个或更多的第一换热管21相连，即一个第一子流道1132在第一管11长度方向上的尺寸大于一个第二子流道1142在第一管11长度方向的尺寸，由此，换热器100的第一换热管21和第二换热管22可按照不同的比例布置，实现换热器100中部分负荷的差异化匹配，使得第一流道113内流通的冷媒更多，提高第一流道113侧和第一换热管21的换热效率。

可以理解的是，本申请并不限于此，在一些可选地实施例中，本申请实施例的换热器100中第一组件3只包括第一板37，或者，第一组件3可以只包括第二板38。第一板37和第二板38有利于提高第一管11的强度，或者在一定的强度要求下，可以减少第一管11的壁厚，降低加工难度。同时第一板37和第二板38可以减少第一管11中容纳制冷剂的内容积，提高换热器的性能的同时，减少制冷剂的充注量。

可以理解的是，本申请并不限于此，在一些可选地实施例中，本申请实施例中第一组件3和第二组件4的结构相同，第一组件3和第二组件4彼此对应地设置在第一管11和第二管12内。
如图15所示，根据本申请实施例的多制冷***空调机组200包括多个制冷***201，多个制冷***201中的至少两个制冷***201共用至少一个换热器100，换热器100为至少两个制冷***201的蒸发器和/或冷凝器，换热器100为本申请任一项实施例中的换热器100。
根据本申请的实施例的多制冷***空调机组包括多个制冷***，多个所述制冷***中的至少两个制冷***共用至少一个上述任一项实施例中的换热器，该换热器通过设置并列的第一管和第二管，在第一管和第二管之间设置多个第一换热管和多个第二换热管，且多 个第一换热管和多个第二换热管沿第一管的长度方向交替布置。在第一管内设置第一组件，以将第一管内的第一主通道分割成第一流道和第二流道，第一流道和第二流道之间不连通。其中，第一流道包括第一孔道和多个第一子流道，多个第一子流道分别与多个第一换热管对应相连，第二流道包括第二孔道和多个第二子流道，多个第二子流道分别与多个第二换热管对应相连。由此，该换热器应用在多制冷空调机组中时，可以使得冷媒只在第一流道和第一换热管内流通，或者，冷媒只在第二流道和第二换热管内流通，或者，冷媒在第一流道、第一换热管、第二流道和第二换热管内均流通。该换热器能够提高换热面积利用率，有利于提高***的性能。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
