在本发明的实施例中，参见图5，第一换热器1是梯形换热器，第二换热器2是矩形换热器，第一连通集流管10的三个第一连通腔室14中的所述两个相邻的第一连通腔室14位于第一换热器1的较宽的一侧。在图示的实施例中，第一连通集流管10的内腔分成相等的三个第一连通腔室14，第二连通集流管20的内腔分成三个相等的第二连通腔室24。第一连通集流管10的隔板30与第二连通集流管20的隔板30在高度方向上分别对齐。在换热器组件100中形成一个S形制冷剂串联回路，并形成三个回路。制冷剂从第二集流管22的两个第二腔室26中的上部第二腔室26进入，并且从第一集流管12的两个第一腔室16中的下部第一腔室16流出。
在本发明的实施例中，参见图10，第一换热器1是矩形换热器，第二换热器2是梯形换热器，第二连通集流管20的三个第二连通腔室24中的所述两个相邻的第二连通腔室24位于第二换热器2的较窄的一侧。
如图1至12所示，根据本发明的实施例的换热器组件100，制冷剂是以串联的方式先后进入梯形换热器和矩形换热器，或者先后进 入矩形换热器和梯形换热器。将梯形换热器和矩形换热器通过铜管以串联的形式连接起来，形成换热器组件。集流管中设置多个隔板，实现不同的流动回路。两个换热器组件拼接成的组合式微通道换热器，能有效增加冷水机组的换热面积，提高换热能力。且制冷剂可以实现同侧或对角方向进出，便于将换热器与机组进行安装连接。
如图11和12所示，两种不同的换热器模块可以拼接成一个组合式的微通道换热器，用于风冷模块化冷水机组上。
图11的微通道换热器是由图2所示的换热器组件和图7所示的换热器组件组合而成。两个换热器组件的进出口接管分别位于梯形换热器和矩形换热器的集流管上，且都在同一侧。图3所示的换热器组件和图8所示的换热器组件可以组合在一起、图4所示的换热器组件和图9所示的换热器组件可以组合在一起、图5所示的换热器组件和图10所示的换热器组件可以组合在一起，进出口接管也都在同一侧。
安装人员在焊接换热器与压缩机和膨胀阀的连接铜管时，可方便地在同一侧进行操作。并且从压缩机出来的制冷剂气体通过三通进入微通道换热器，进口铜接管长度是一样的，不会出现一个换热器组件有复杂的长接管，这样能使两个换热器组件的压降较为平均，制冷剂分配更为均匀。
图12的微通道换热器是由图5所示的换热器组件和图10所示的换热器组件组合而成。两个换热器组件的进口接管都在同一侧，出口接管都在处于对角线方向上的另一侧。压缩机出来的制冷剂气体通过三通从矩形换热器和梯形换热器的集流管的上部进入，在各自的换热器组件中进行一个三回路流程换热后，分别从对角线方向的矩形和梯形换热器集流管下部流出。同样地，从三通到进口的铜接管长度是一样的，可以实现制冷剂的均匀分配。
如图1至12所示，根据本发明的实施例的换热器组件100，增大换热面积，制冷剂分配均匀，提升换热能力。与传统的风冷模块冷水机组换热器相比，充分利用了两侧V形区域，面积增加了约22％；且从三通到换热器组件的进口的铜接管长度一致，实现两个换热器组件的制冷剂均匀分配，换热能力得到有效提升。此外，流路和接管形 式多样。可实现两、三或四回路，流路也有串联或串并联的关系，进出口接管可在同一侧也可在对角线侧。多样的流路和接管形式，能够满足不同客户机组设置和不同工况的需要。再者，根据本发明的实施例的换热器组件100运输方便、安装简便。拆成平板状态的换热器芯体进行装箱运输，不占用空间；客户通过U形铜管、笛形管或三通管等将四个平板芯体组合成整体的换热器。
