参见图6，根据本发明的实施例，管组件1还包括：换热片6，换热片6沿周向方向具有波状形状，波状形状的换热片6具有邻近所述外周壁10的外表面的多个波谷部分64，多个波谷部分64中的至少一个或所有多个波谷部分64与所述外周壁10的外表面12相接。 该换热片6可以作为翅片用来和空气换热。
参见图1至10，在本发明的一些实施例中，所述分隔壁3具有通孔，多个腔室中的至少两个通过所述通孔连通。
参见图8至10，在本发明的一些实施例中，所述波状形状的分隔壁3在周向方向上具有沿纵向方向延伸的第一接合面36和沿纵向方向延伸的第二接合面37；以及第一接合面36和第二接合面37相互接触并连接。例如，参见图8、图9，所述波状形状的分隔壁3包括：第一组波状形状的分隔壁3，第一组波状形状的分隔壁3在周向方向上具有沿纵向方向延伸的两个所述第一接合面36；和第二组波状形状的分隔壁3，第二组波状形状的分隔壁3在周向方向上具有沿纵向方向延伸的两个所述第二接合面37；以及第一组波状形状的分隔壁3的两个第一接合面36与第二组波状形状的分隔壁3的两个第二接合面37分别相互接触并连接。
参见图8，在本发明的一些实施例中，所述外周壁10和所述内周壁5中的至少一个具有大致圆形的横截面；以及第一接合面36和第二接合面37相对于所述外周壁10和所述内周壁5中的所述至少一个的径向方向倾斜。根据本发明的实施例，第一接合面36和第二接合面37在与管组件1的轴向方向垂直的平面中可以具有互补的弯曲形状。例如，第一接合面36和第二接合面37在与管组件1的轴向方向垂直的平面中具有互补的L或S形的形状。由此，增加了第一接合面36和第二接合面37的接触面，焊接后强度大，不易泄漏。
在图10所示的实施例中，所述外周壁10和所述内周壁5直接连接，例如，所述外周壁10和内周壁5由一片板折弯形成，或者所述外周壁10、分隔壁3和内周壁5由一片板折弯形成。
管组件1所用的板或片可以是独立的数片，如每层用一片，翅片用一片。板或片的厚度，材料等可以不一样。管组件1上可以加工出槽或孔等用来做集流管用。腔室的个数可以从1到20个。管组件1的最外层和翅片接触。
采用管组件1形成换热器的步骤包括：把管组件1***多层翅片的翅片孔中；对管组件1进行胀管使管组件1与翅片孔翻边接触；以 及把翅片与管组件1焊接一起。
采用根据本发明的实施例的管组件1，可以降成本，因为折弯形成的管的价格可以比较低。此外可以提高换热效率，因为通过折弯形成微通道结构，由此加大换热面积，提高换热量。此外，可以提高抗腐蚀能力，因为折弯管所用的材料可以在内外都加上复合层，管子可以做到内外都抗腐蚀。
尽管描述了上述实施例，但是上述实施例中的一些特征可以进行组合形成新的实施例。
