除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
请参考图1至图2，本申请提供一种集气管组件100，该集气管组件100应用于空调系统的制冷剂管路中，大多连接于冷凝器、蒸发器的进出口端，通常被用来分配制冷剂的流动。
具体地，集气管组件100包括主管10及支管20，支管20固定于主管10上，并与主管10的内部连通设置；集气管组件100还包括套管30，主管10的外侧壁开设有安装孔11，套管30的一端固定于安装孔11内，另一端位于主管10外侧，支管20的一端从套管30远离主管10的一端伸入套管30内，并与套管30焊接连接。
需要说明的是，通常的集气管组件，都是将主管与支管直接进行炉中钎焊，使得焊接空间受限，而且直接炉中钎焊后支管的硬度过低，运输过程中易变形。而本实施方式中，通过采用在主管10和支管20之间连接套管30的方式，解决了主管10与支管20直接焊接连接导致的支管20硬度太低，且运输时易变形的问题。
可以理解的是，通常情况下来说，由于主管10和支管20之间直接进行焊接的时候会受到体积的限制，当支管20的体积较大时，难以实现二者的焊接；而套管30的体积远远小于支管20的体积，因此本申请中采用套管30作为主管10和支管20焊接的过渡管，先将套管30和主管10炉中钎焊，然后再焊接支管20，解决了主管10与支管20直接焊接连接导致的支管20硬度太低，且运输时易变形的问题。
可选地，在本实施例中，主管10的材质为SUS304不锈钢；当然，在其他实施例中，主管10的材质为碳钢或者铝，在此不作限定。
可选地，在本实施例中，支管20的材质选用TP2Y铜材；当然，在其他实施例中，支管20的材质还可以选用其他类型，在此不作限定。
在本实施例中，主管10上开设有多个安装孔11，多根支管20对应的安装于每个安装孔11中。
如图1所示，主管10上设有凸部12，安装孔11开设于凸部12上，且凸部12与主管 10设置为一体式。
需要说明的是，凸部12是由主管10从主管10内部朝向主管10外部的方向冲压而成的，如此便于主管10与套管30之间的焊接。
具体地，沿主管10轴向方向，主管10的一端还具有连接段13，连接段13与制冷系统的管路件连接，多根支管20开设于主管10的侧面，支管20用于与系统的换热器连接。
进一步地，连接段13的端部连接有铜套131，由于主管10以及连接段13均为不锈钢材质，因此铜套131的设置便于连接段13与使用铜金属材料制成的制冷系统的管路件连接。
具体地，主管10为直管结构，连接段13为折弯角度大致在180°的弯管段，这样使得连接段13和主管10大致平行，便于在制冷系统中，系统管路件与集气管组件100大致平行设置，减少装配空间，结构更为紧凑，提升了空间利用率。
如图2所示，套管30包括缩口段31和扩口段32，缩口段31与主管10连接，扩口段32与支管20连接，如此增强了主管10与支管20之间的焊接牢靠性。
可选地，在本实施例中，套管30的材质选用铜材；当然，在其他实施例中，支管20的材质还可以选用其他类型，在此不作限定。
可以理解的是，由于铜材的热胀冷缩率要高于不锈钢，因此套管30的缩口段31与主管10焊接时，套管30的膨胀幅度要大于主管10，这样便会使得两者之间的焊接更加牢固、可靠。
可选地，在本实施例中，缩口段31与主管10通过炉中钎焊的方式进行焊接，如此不仅提升了焊接效率，也降低了成本；当然，在其他实施例中，缩口段31与主管10也可以采用其他方式进行焊接，在此不作限定。
可选地，在本实施例中，扩口段32与支管20通过火焰焊接的方式进行焊接，如此使得工艺过程更为简单，操作技术更加容易被掌握；当然，在其他实施例中，扩口段32与支管20也可以采用其他方式进行焊接，在此不作限定。
进一步地，套管30还包括限位段33，限位段33位于缩口段31和扩口段32之间，限位段33的外径大于安装孔11的孔径，限位段33限制了套管30过度伸入主管10中，起到了定位作用，确保了焊料与焊缝的充分接触，避免泄漏。
进一步地，主管10的直径定义为D，沿安装孔11的轴线方向，套管30通过安装孔11插入主管10的深度定义为H，D和H满足以下关系式：H≤0.5D；若套管30插入主管10过深，则会导致成本增高，还会引起阻塞；若套管30插入主管10过浅，则会使得套管30在与主管10焊接的时候焊接发黑。
在本实施例中，多根支管20和多个套管30均为冲制而成，因冲压由模具保证，因此在保证了零件的一致性的同时也保证了零件的精度。
在本实施例中，该集气管组件100的制造工艺包括以下步骤：
第一步，制备主管10，截取合适长度的不锈钢管，对不锈钢管倒角处理，然后使用缩口机对不锈钢管两端进行缩口，再使用拉拔机在不锈钢管的侧壁拉拔出用于焊接套管30的安装孔11，然后使用弯管机对主管10的连接段13进行弯管，最后清洗烘干；笫二步，制备支管20，截取适合长度的铜管，对铜管进行倒角处理，最后进行清洗烘干；笫三步，制备套管30，截取适合长度的铜管，对铜管进行倒角处理，然后使用扩口机对铜管用于焊接支管20的一端根据要求进行扩口，使铜管的扩口段直径与支管20相匹配，然后使用缩口机对铜管用于焊接主管10的一端根据要求进行缩口，使铜管的缩口段直径略小于主管10侧壁的安装孔11，最后进行清洗烘干；第四步，装配，将套管30的缩口段31插入主管10侧壁的安装孔11，将固态环状的青铜焊料套装入支管20；第五步，焊接，将装配好的套管30和主管10通过焊炉，焊炉温度控制在930℃，套管30和主管10通过焊炉的速度在0.3米/分；第六步：再将支管20插入套管30的扩口段32使得支管20和主管10相互固定焊接，可以采用火焰焊、激光焊或者氩弧焊，第七步，测漏检验，查看焊接好的集气管组件100有没有焊接不良。
在焊接集气管组件100中的主管10和支管20的过程中，通过在主管10和支管20之间焊接设置起到过渡作用的套管30，便解决了主管10与支管20炉焊导致支管20硬度降低，运输时易变形的问题。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
