现有集气管一般在主集管中设置多个集气孔，每个集气孔处均与一根支管进行焊接，因支管要与换热管进行连通，会导致出现支管与主集管的长度过长的情况，制造成本高；同时，管道的振动会对主集管上长度过长的支管的强度造成影响，从而降低空调系统中的热交换效率。
发明内容

请参阅图1，本申请提供一种集气管100，该集气管100应用于空调制冷系统，用于优化制冷剂的流路结构，以使制冷剂能够进行充分的热量交换。
现有集气管一般在主集管中设置多个集气孔，每个集气孔处均与一根支管进行焊接，因支管要与换热管进行连通，会导致出现支管与主集管的长度 过长的情况，制造成本高；同时，管道的振动会对主集管上长度过长的支管的强度造成影响，从而降低空调系统中的热交换效率。
请参阅图1，本申请提供的集气管100，包括主集管10、弯管20、第一支管30以及第二支管40，主集管10上开设有第一集气孔11，第一支管30安装于第一集气孔11内并与主集管10连通；弯管20设于主集管10的一端，并与主集管10连通；且弯管20上开设有第二集气孔21，第二支管40安装于第二集气孔21内并与弯管20内部连通；第二支管40远离主集管10的一端与换热管(图未示)连通，通过在弯管20上开设第二集气孔21，并将第二支管40安装于第二集气孔21内并与弯管20内部连通，能够降低第二支管40的长度。
因换热管的位置始终为固定的，若将第二支管40设置在主集管10上，需要加长第二支管40的长度才能与该处的换热管进行连通，但若将第二支管40的长度设置的过长，管道的振动会对第二支管40的强度造成影响，故将第二支管40设置在弯管20上，直接与该处的换热管进行连通，能够减小第二支管40的长度，且能够降低振动对第二支管40强度的影响；同时，能够降低主集管10的长度，无需在主集管10上再开设集气孔，将支管与集气孔进行连接，从而降低制造成本，提高集气管100的强度，避免集气管100产生变形的问题。
进一步地，请参阅图2-图4，弯管20在第二集气孔21处设有第二翻边22，第二翻边22围设于第二集气孔21周向，第二支管40与第二翻边22连接；在第二集气孔21处设有第二翻边22，便于第二支管40与弯管20的连接，能够起到定位及保护作用；若第二支管40直接连接在弯管20的第二集气孔21处，不易控制第二支管40的连接位置，同时，在连接过程中容易将 弯管20损坏。
在本申请中，弯管20由主集管10的一端延伸形成，在一实施例中，弯管20可由主集管10的一端通过拉伸形成，便于加工，降低制造成本；主集管10采用不锈钢材质，便于主集管10一体式折弯成型，提升集气管100的硬度；同时，由于铜材料的价格较高，为了降低生产成本，本申请采用不锈钢材料代替铜材料来加工主集管10。
在一实施例中，第二翻边22与弯管20设置为一体式，便于第二支管40与弯管20的连接，能够节省时间，降低制造成本；且在设置第二翻边22时，需要先将主集管10的一端拉伸形成弯管20，再对弯管20处进行切孔，形成第二集气孔21，再进行翻边，从而形成第二翻边22；避免先在主集管10上切孔，切孔后翻边，再拉伸形成弯管20，如此会产生变形的问题。而第一翻边12的设置是直接在主集管10上进行切孔，形成第一集气孔11，切孔后进行翻边，从而形成第一翻边12，因为主集管10无需拉伸折弯，无加工变形的风险。
可选地，第二支管40与第二翻边22之间固定连接；进一步地，第二支管40与第二翻边22之间可通过焊接连接。焊接的连接稳固性好、操作灵活、维护方便且焊接使用的设备简单、成本低。
在一实施例中，第二集气孔21的轴线与主集管10的轴线垂直设置，便于加工，并且，第二集气孔21的设置便于与第二支管40进行连接。
在另一实施例中，第二集气孔21设于弯管20的外侧，且第二集气孔21的轴线与主集管10的轴线平行，便于加工，并且，第二集气孔21的设置便于与第二支管40进行连接。
请参阅图1及图2，第二集气孔21位于弯管20的弯道中心位置；因弯 管20在折弯时，材料经过拉伸会产生变形，管壁慢慢由厚变薄，且弯管20最外边缘处的拉伸变形量最大，若在弯管20最外边缘处设置第二集气孔21，容易出现开裂的情况；而弯管20的弯道的中心位置受力比较平衡，不容易产生开裂的问题，故将第二集气孔21设置于弯管20的弯道中心位置，能够提高与第二支管40的连接强度。
请参阅图2及图3，主集管10在第一集气孔11处设有第一翻边12，第一翻边12围设于第一集气孔11的周向，第一支管30与第一翻边12连接；在第一集气孔11处设有第一翻边12，便于第一支管30与主集管10的连接，能够起到定位及保护作用；若第一支管30直接连接在主集管10的第一集气孔11处，不易控制第一支管30的连接位置，同时，在连接过程中容易将主集管10损坏。
请参阅图1，集气管100还包括铜接头50，铜接头50与弯管20远离主集管10的一端连接，在制冷技术领域，一般使用空调的铜管组作为连接管连接两个零部件，为了与铜管组连接方便，零部件也采用铜材料制成，但由于铜材料的价格较高，为了降低生产成本，本申请采用不锈钢材料代替铜材料制作部分零部件。制造过程中，需要将铜管组与不锈钢零部件的不锈钢管焊接在一起，即在本申请中，铜管组与本申请中的不锈钢材质的弯管20焊接，但是铜材料与不锈钢材料的焊接特性相差很大，因此直接将铜管组与不锈钢材质的弯管20焊接在一起的工艺难度较大，故在不锈钢材质的弯管20外侧套设一个铜接头50，然后将铜管组直接焊接在铜接头50上，降低工艺难度，便于加工且降低成本。
请参阅图1，集气管100还包括端盖60，端盖60盖设于主集管10远离弯管20的一端。
本申请还提供一种换热器组件(图未示)，包括换热器以及集气管100，集气管100与换热器上的换热管连接，且集气管100采用上述任意一项集气管100。
在本申请中，通过在弯管20上开设第二集气孔21，并将第二支管40安装于第二集气孔21内并与弯管20内部连通，能够降低第二支管40的长度；因换热管的位置始终为固定的，若将第二支管40设置在主集管10上，需要加长第二支管40的长度才能与该处的换热管进行连通，但若将第二支管40的长度设置的过长，管道的振动会对第二支管40的强度造成影响，故将第二支管40设置在弯管20上，直接与该处的换热管进行连通，能够减小第二支管40的长度，且能够降低振动对第二支管40强度的影响；同时，能够降低主集管10的长度，无需在主集管10上再开设集气孔，将支管与集气孔进行连接，从而降低制造成本，提高集气管100的强度，避免集气管100产生变形的问题。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上实施方式的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式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。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本申请，而并非用作为对本申请的限定，只要在本申请的实质精神范围内，对以上实施方式所作的适当改变和变化都落在本申请要求保护的范围内。
