参见图1至图14，在本发明的实施例中，凸起的形状可以是矩形、梯形、三角形、圆形等。凸起形成的凹凸部分用于存储制冷剂气液混合物。
参见图1至图5，在本发明的实施例中，所述突出壁部3从主体壁部10的第一侧11沿第二方向D2朝外突出；以及所述主体壁部10限定第一腔体部51，所述突出壁部3限定第二腔体部52，并且所述第一腔体部51和所述第二腔体部52连通。所述突出壁部3限定的第二腔体部52可以具有任何形状，例如，矩形、梯形、三角形、圆形等。使用中，所述突出壁部3限定的第二腔体部52可以大致位于分配管组件1的底部。所述第二腔体部52的体积小于所述第一腔体部51的体积，例如，所述第二腔体部52的体积是所述第一腔体部51的体积和所述第二腔体部52的体积之和的1％-30％。

参见图9至图10，在本发明的实施例中，所述突出壁部3从主体壁部10的第二侧12沿第二方向D2朝内突出；以及所述主体壁部10的内壁和所述突出壁部3的外壁限定第一腔体部51，所述突出壁部3的内壁(或者两个突出壁部3之间)限定第二腔体部52，并且所述第一腔体部51和所述第二腔体部52在主体壁部10的第二方向D2上的第一侧11连通。例如，所述突出壁部3具有两个面向与第一方向D1和第二方向D2垂直的第三方向D3的侧壁部31，所述两个侧壁部31之间的、在主体壁部10的第二方向D2上的第二侧12的间隙形成所述分配孔4。所述第二腔体部52的体积小于所述第一腔体部51的体积，例如，所述第二腔体部52的体积是所述第一腔体部51的体积和所述第二腔体部52的体积之和的1％-30％。
参见图11，在本发明的实施例中，所述突出壁部3在第二方向D2上的第一侧具有第一边缘部311，并且在第二方向D2上的与第一侧相反的第二侧具有第二边缘部312，所述突出壁部3的所述第一边缘部311与所述主体壁部10的第一侧11连接，并且所述突出壁部3的所述第二边缘部312与所述主体壁部10的第二侧12连接。例如，分配管组件1还包括：形成于主体壁部10的第一侧11的、用于分配制冷剂的分配孔4。
参见图9至图10，在本发明的实施例中，所述两个侧壁部31中的每一个在第二方向D2上的第一侧具有第一边缘部311，并且在第二方向D2上的与第一侧相反的第二侧具有第二边缘部312，所述两个侧壁部31中的至少一个的所述第一边缘部311与所述主体壁部10的第一侧11连接，并且所述两个侧壁部31中的每一个的所述第二边缘部312与所述主体壁部10的第二侧12连接。在所述两个侧壁部31的所述第一边缘部311与所述主体壁部10的第一侧11连接的情况下，例如，分配管组件1还包括：形成于主体壁部10的第一侧11的、用于分配制冷剂的分配孔4，或者形成于所述两个侧壁部31中的至少一个中且邻近所述第一边缘部311的入口，如上所述所述两个 侧壁部31之间的、在主体壁部10的第二方向D2上的第二侧12的间隙形成所述分配孔4。
参见图9至图10，在本发明的实施例中，所述两个侧壁部31中的每一个在第二方向D2上的第一侧具有第一边缘部311，并且在第二方向D2上的与第一侧相反的第二侧具有第二边缘部312，所述两个侧壁部31中的至少一个的所述第一边缘部311与所述主体壁部10的第一侧11间隔开，并且所述两个侧壁部31中的每一个的所述第二边缘部312与所述主体壁部10的第二侧12连接。
根据本发明的实施例，如图9所示，所述主体壁部10和左侧的侧壁31形成的空间可以不用于制冷剂分配，仅仅用于降低集流管的内部体积。例如，所述主体壁部10和左侧的侧壁31形成的空间可以是封闭的。
根据本发明的实施例，如图1至图8所示，分配管组件1的主体壁部10具有侧壁15和顶壁16。在集流管组件20中，在集流管21的内壁和分配管组件1之间的间隙从突出壁部3的两个侧壁31或从突出壁部3或从分配管组件1的底部到主体壁部10的侧壁15的顶点逐渐减小，在集流管21的内壁和分配管组件1之间从突出壁部3的两个侧壁31到主体壁部10的侧壁15的顶点形成第一混合腔81，而分配管组件1的顶壁16上方的空间形成第二混合腔82。突出壁部3形成的第二腔体部52形成储液腔，所述主体壁部10形成的第一腔体部51形成分离腔。第一腔体部51的体积大于第二腔体部52的体积，第一腔体部51促进两相流制冷剂的气液分离，使分离出的液体制冷剂存储在第二腔体部52中，并经过分配孔4进入第一混合腔81和第二混合腔82，然后进入换热管9。由此，通过减小制冷剂进入换热管9之前的第一混合腔81的体积，让制冷剂在第一混合腔81里面充分混合后入进入换热管9。第一混合腔81的体积可以小于第二混合腔82的体积。
参见图4，集流管21可以是由多个部件组成的集流管。
参见图13，集流管21上设有供换热管插入的槽，分配管组件1的第二方向D2的第二侧12可大致与集流管上的供换热管插入的槽 相对。
在图9和图10所示的实施例中，两个侧壁31在第三方向D3上可以位于主体壁部10限定的第一腔体部51的中部或中央，两个侧壁31可以在第二方向D2上延伸。由此，使得制冷剂在主体壁部10的顶部处分散的更加均匀。分配管组件1的主体壁部10的弧形外壁可与集流管接触或分离，或与集流管成一体，例如可以取消分配管组件1的主体壁部10的弧形外壁。此外，在图9至图10所示的实施例中，所述突出壁部3或两个侧壁31之间限定的第二腔体部52以及分配管组件1或第一分配管的外壁或主体壁部10的外壁与集流管21的内壁之间的间隙构成混合腔，主体壁部10限定的第一腔体部51构成分离腔，而主体壁部10限定的第一腔体部51底部存储液体制冷剂。主体壁部10的底部和侧壁与分配管组件1之间的间隙可大致相同。在图11所示的实施例中，分配管组件1或第一分配管的外壁或主体壁部10的外壁与集流管21的内壁之间的间隙构成混合腔，主体壁部10的底部和侧壁与集流管21的内壁之间的间隙构成第一混合腔81(参见图1)。
在图6至图8所示的实施例中，主体壁部10限定的第一腔体部51构成分离腔，而主体壁部10限定的第一腔体部51底部存储液体制冷剂。根据本发明的实施例的换热器，组装简单，制冷剂气液混合物在进入换热管之前进行了充分混合，最大程度实现了制冷剂的均匀分配。换热器性能得到很大程度的提高。此外，由于混合腔的空间限制，保证了制冷剂的最小流速，避免了油积存。再者，减少了使用该集流管组件的换热器的内容积，从而减少了整机系统充注量。
根据本发明的实施例，参见图12至19，分配管组件1还包括第二分配管101，所述第二分配管101插入第一分配管中并且具有分配孔。第二分配管101可以是传统的分配管，制冷剂从第二分配管101流入第一分配管1，然后再流入换热管9。
参见图12至图19，集流管包括端盖23，集流管组件1还包括：设置在分配管组件1或第一分配管的端部上的第一连接部；以及设置在集流管21的端盖23上的第二连接部，所述第一连接部与第二连接 部连接，以将分配管组件2固定在集流管21中。例如，如上所述，设置在分配管组件1或第一分配管的端部上的第一连接部是凸起17；设置在集流管21的端盖23上的第二连接部是开口或凹槽24，所述凸起17插入开口或凹槽24中。凸起17可以从突出壁部3的端部或端面突出。
根据本发明的实施例，参见图1至图8、11，集流管21的内壁与分配管组件1或第一分配管的外壁之间的间隙构成第三腔体部(即构成混合腔，混合腔包括第一混合腔81和第二混合腔82)，第三腔体部的体积或横截面面积小于分配管组件1或第一分配管的内壁限定的体积或横截面面积，并且是分配管组件1或第一分配管的内壁限定的体积或横截面面积的1/20～1/2。
此外，参见图9至图10，在本发明的实施例中，流管21的内壁与分配管组件1或第一分配管的外壁之间的间隙和所述第二腔体部52构成第三腔体部(即构成混合腔)。集流管21的内壁与分配管组件1或第一分配管的外壁之间的间隙的体积或横截面面积和所述第二腔体部52的体积或横截面面积之和小于所述第一腔体部51的体积或横截面面积，并且是所述第一腔体部51的体积或横截面面积的1/20～1/2。
在上述实施例中的分配管组件1或第一分配管的内壁限定的体积和横截面面积以及第二腔体部52的体积和横截面面积不包括如图9所示的左侧的不用于制冷剂分配的空间的体积和横截面面积。
由于分离腔较大，混合腔较小，使得制冷剂进入分离腔后易于气液分层，液体沉积在分配管组件1的底部(例如突出壁中)。由于气态制冷剂速度快，会推着液态制冷剂从分配孔中喷出，这个过程中气态和液态制冷剂混合，然后进人混合腔。由于混合腔体积较小，气态和液态制冷剂会进一步混合均匀后进入换热管，从而提高换热器的换热效率。
需要说明的是，上述实施例的部分技术特征或全部技术特征可以相互组合形成新的实施例。
