请参阅图1-图6，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。
通常集气管包括主集管，且部分主集管采用不锈钢材质加工形成，并将不锈钢材质的主集管与黄铜接头直接焊接，再通过黄铜接头与空调系统的铜管组连接，但如此将不锈钢主集管与黄铜接头直接焊接会导致不锈钢主集管表面发黑，影响不锈钢主集管的耐腐蚀性，导致集气管的强度降低，从而降低空调系统中的热交换效率。
请参阅图1-图6，本申请提供的集气管100包括不锈钢主集管10、紫铜套20以及黄铜接头30，紫铜套20具有相对设置的第一端21及第二端22，不锈钢主集管10设于紫铜套20的第一端21并与紫铜套20焊接；黄铜接头30设于紫铜套20的第二端22，并与紫铜套20焊接；通过在黄铜接头30与不锈钢主集管10之间设置紫铜套20，并将不锈钢主集管10与紫铜套20的第一端21焊接，黄铜接头30与紫铜套20的第二端22焊接，能够避免将黄铜接头30直接焊接在不锈钢主集管10上，导致不锈钢主集管10表面发黑的情况，提高集气管100的耐腐蚀性以及强度，从而提高空调系统中的热交换效率；同时，采用紫铜套20进行转接，化学性能稳定、持久耐用、耐热、耐压且耐腐蚀性强，并且，连接方便、成本较低、易于维护，具有优异的抗振及抗冲击性。
在本申请中，主集管采用不锈钢材质，能够提升集气管100的硬度；同时，由于铜材料的价格相对较高，为了降低生产成本，采用不锈钢材料代替铜材料来加工主集管，形成 本申请中的不锈钢主集管10；同时，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主集管10焊接。
在本申请中，当空调系统空间太小焊接不方便时，采用黄铜接头30进行螺纹固定，将黄铜接头30与铜管组进行连接，降低工艺难度，便于加工且降低成本。
进一步地，在一实施例中，请参阅图1-图3，不锈钢主集管10的一端从第一端21伸入紫铜套20内，紫铜套20的第二端22伸入黄铜接头30内；其中，伸入紫铜套20内的部分不锈钢主集管10位于黄铜接头30内；能够使不锈钢主集管10与黄铜接头30之间的连接更稳固，提高黄铜接头30与不锈钢主集管10的连接强度。
具体地，紫铜套20呈管状，且紫铜套20的长度定义为H1，其中，H1满足以下关系式：H1≥15mm；当H1≥15mm时，能够保护不锈钢主集管10不被烧伤，增强集气管100的强度，使集气管100持久耐用；若紫铜套20的长度太短，在黄铜接头30与紫铜套20进行焊接的过程中，会导致烧伤不锈钢主集管10，集气管100的强度会降低，从而降低空调系统中的热交换效率。
请参阅图3，紫铜套20插入黄铜接头30一端的内径定义为R1，黄铜接头30的内径定义为R2；其中，R1和R2满足以下关系式：R1>R2，便于紫铜套20与黄铜接头30进行焊接。
请继续参阅图3，不锈钢主集管10的一端设有第一缩口段11，第一缩口段11插入紫铜套20内，第一缩口段11的内径定义为R3；其中，R2和R3满足以下关系式：R3>R2；能够保证冷媒的充分流通，不会存在节流的情况；若第一缩口段11的内径小于黄铜接头30的内径，冷媒从第一缩口段11流向黄铜接头30的过程中会对冷媒的流通产生节流，降低空调系统中的热交换效率。
在另一实施例中，请参阅图4-图6，紫铜套20包括第一段23、第二段24以及第三段25，第二段24设于第一段23和第三段25之间，第一段23与不锈钢主集管10焊接，第三段25至少部分伸入黄铜接头30内，并与黄铜接头30焊接；便于紫铜套20与黄铜接头30及不锈钢主集管10之间的焊接，并且，能够避免将黄铜接头30直接焊接在不锈钢主集管10上，导致不锈钢主集管10表面发黑的情况，提高集气管100的耐腐蚀性以及强度，从而提高空调系统中的热交换效率。
进一步地，第一段23设置为扩口段，扩口段套设于不锈钢主集管10；扩口段能够对 不锈钢主集管10伸入紫铜套20的距离起到限位作用，若不锈钢主集管10伸入过长，不便进行焊接，若不锈钢主集管10伸入过短，会产生焊接不牢固的问题；并且，第一段23设置为扩口段，加工方便且便于不锈钢主集管10的插入，同时，便于不锈钢主集管10与紫铜套20进行焊接，增强焊接的稳固性。
进一步地，第三段25设置为第二缩口段，第二缩口段的至少部分插入黄铜接头30内；将第三段25设置为第二缩口段，加工方便且便于插入黄铜接头30中，增强焊接的稳固性。
具体地，请参阅图6，黄铜接头30靠近不锈钢主集管10的一端与第三段25靠近第二段24的一端存在间隙，便于黄铜接头30与紫铜套20焊接时焊料的填充。
请参阅图1-图6，黄铜接头30内设置定位台阶31，紫铜套20的第二端22插入黄铜接头30内，并抵靠于定位台阶31；将黄铜接头30内设置有定位台阶31，能够对紫铜套20的伸入黄铜接头30的距离进行限位，使紫铜套20在合适的位置与黄铜接头30进行焊接，确保焊接的牢固性；若紫铜套20伸入过长，不便进行焊接，若紫铜套20伸入过短，会产生焊接不牢固的问题。
在本申请中，不锈钢主集管10与紫铜套20通过炉中钎焊连接；和/或，黄铜接头30与紫铜套20通过火焰焊接；炉中钎焊所使用的钎焊材料的保护气氛便宜，能够降低成本；火焰焊接操作简单、使用便捷且成本低。
本申请提供的集气管100还包括多根支管40，且多根支管40间隔地安装于主集管上，并分别与主集管内部连通，能够提高空调系统中的热交换效率。
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。
