具体实施方式
下面结合附图及具体实施方式对本发明做进一步说明。
根据本发明的实施例的空调***包括换热器。具体而言，根据本发明的实施例的空调***包括压缩机、作为蒸发器的换热器、作为冷凝器的换热器、膨胀阀等。
参见图1至图4，根据本发明的实施例的换热器100包括：沿第一方向延伸的集流管1，所述集流管1具有贯穿集流管1的管壁10的第一开口11；与集流管1并排设置的管状件2，所述管状件2具有贯穿管状件2的管壁20的第二开口21；以及连接管组件3。换热器100还可以包括与所述集流管1连接并流体连通的多个换热管5以及与多个换热管5交替排列的多个翅片6。参见图1至图4，所述连接管组件3包括：连接管30，所述连接管30沿与第一方向交叉的第二方向延伸并且具有相对的第一端部31和第二端部32；以及分别从所述第一端部31和第二端部32朝向径向外侧延伸的第一凸缘部310和第二凸缘部320。第一凸缘部310的朝向所述集流管1的表面311与集流管1的管壁10的外表面12连接并且第二凸缘部320的朝向所述管状件2的表面321与管状件2的管壁20的外表面22连接使得所述集流管1与所述管状件2通过所述第一开口11、所述连接管30和第二开口21流体连通。集流管1、管状件2和连接管30可以是圆管等。可以设置一个或多个(例如两个、三个等)连接管组件3。根据本发明的示例，所述连接管组件3在所述集流管1的径向方向上的外侧并且在所述管状件2的径向方向上的外侧。
根据本发明的实施例，参见图2至图4，第一凸缘部310和第二凸缘部320具有马鞍的形状。连接管组件3通过由管材通过在管材的两端冲压形成。第一凸缘部310和第二凸缘部320作为焊接部具有贴合集流管和管状件的弧面。第一凸缘部310的表面311和第二凸缘部320的表面321与集流管和管状件贴合。在钎焊炉内，集流管的表面的复合层熔化填充至集流管与第一凸缘部310的表面311之间的间隙，而管状件2的表面的复合层熔化填充至管状件2与第二凸缘部320的表面321之间的间隙，从而完成连接管组件3与集流管和管状 件2的焊接。根据本发明的实施例，连接管30的管壁的厚度大致均匀，并且连接管组件3不需要***集流管的管壁中的开口和管状件2的管壁中的开口。由于第一凸缘部310的表面311和第二凸缘部320的表面321为焊接面，由此增大了焊接面积，降低了焊接难度，并且焊接质量更加可靠。此外，连接管组件3不需要***集流管的管壁中的开口和管状件2的管壁中的开口，因此不会阻碍流体流动，并且压降较小，同时连接管30的内径可以等于开口的直径，因此连接管30的水力直径较大，因而，压降较小。
根据本发明的实施例，参见图2至图4，第一凸缘部310的朝向所述集流管1的表面311与集流管1的管壁10的外表面12的围绕第一开口11的对应部分具有相同的形状，并且第二凸缘部320的朝向所述管状件2的表面321与管状件2的管壁20的外表面22的围绕第二开口21的对应部分具有相同的形状。即，第一凸缘部310的表面311与集流管1的管壁10的外表面12的围绕第一开口11的环形部分相对应并具有相同的形状，而第二凸缘部320的表面321与管状件2的管壁20的外表面22的围绕第二开口21的环形部分相对应并具有相同的形状。例如，第一凸缘部310的朝向所述集流管1的表面311与集流管1的管壁10的外表面12的围绕第一开口11的对应部分具有部分圆柱面的形状，并且第二凸缘部320的朝向所述管状件2的表面321与管状件2的管壁20的外表面22的围绕第二开口21的对应部分具有部分圆柱面的形状。
根据本发明的实施例，参见图1、图2、图4，所述集流管1的轴线与所述管状件2的轴线之间的角度在0度至5度的范围内。例如，所述集流管1的轴线与所述管状件2的轴线相互平行。所述连接管30的轴线与所述集流管1的轴线之间的角度在85度至90度的范围内。例如，所述连接管30的轴线与所述集流管1的轴线可以相互垂直。在图示的示例中，所述集流管1的轴线与所述管状件2的轴线平行并且所述连接管3的轴线与所述集流管1的轴线和所述管状件2的轴线垂直。
根据本发明的实施例，参见图1、图2、图4，所述管状件2是 集流管、分配集管、收集集管1或储存罐等。
根据本发明的实施例，参见图4，所述第一开口11的直径和所述第二开口21的直径中的每一个与所述连接管30的内径的比值在0.95至1.05的范围内。在图示的示例中，所述第一开口11的直径和所述第二开口21的直径中的每一个与所述连接管30的内径相等，所述连接管30的内径在整个长度上相同。
根据本发明的实施例，参见图1至图4，所述集流管1的管壁10的外表面12和所述管状件2的管壁20的外表面22是圆柱面，并且第一凸缘部310的朝向所述集流管的表面311和第二凸缘部320的朝向所述管状件2的表面321具有部分圆柱面的形状。
根据本发明的实施例，参见图1至图4，连接管组件3通过由管材通过在管材的两端冲压形成。连接管的管壁的厚度和第一凸缘部和/或第二凸缘部的厚度相等。所述连接管的管壁具有均匀的厚度。需要说明的是由于在冲压成型过程中，管材的厚度会有较小变化，此处的“相等”可以是大致相等。第一凸缘部310和第二凸缘部320作为焊接部具有贴合集流管和管状件的弧面。管材内侧具有作为焊料的复合层。由此，例如管状件2可不带有复合层。在钎焊过程中，连接管组件3的第一凸缘部310的表面和第二凸缘部320的表面的复合层用于焊接，可避免带有复合层的管状件2在钎焊过程中由于焊料流动堆积产生的焊瘤。管通常由板材卷制而成，复合层通常是在板材成型时均匀附着在板材表面。根据本发明的实施例的集流管1上和换热管5连接的位置处可以吸收焊料，在钎焊过程中由于焊料流动堆积产生焊瘤的情况可能并不明显；而对于管状件2，由于可吸收焊料的位置有限，如果管状件2带有焊料，则更容易在钎焊的过程中由于焊料流动堆积产生焊瘤。
采用根据本发明的实施例的换热器100，可以提高换热器100的质量。
此外，采用根据本发明的实施例的换热器100，可以强化连接管组件3与集流管1和管状件2焊接可靠性，增大集流管1和连接管30的流通面积，并减小集流管1和连接管30引起的压降，此外可以 防止在管状件2上形成焊瘤。
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。
