请参见图1至图3，本申请提供一种不锈钢集气管组件100，应用于制冷系统中，供制冷剂流动，并且解决了不锈钢主管10和支管20的连接问题。
不锈钢集气管组件100，包括不锈钢主管10、支管20以及连接管30，不锈钢主管10与支管20通过连接管30连接且连通。
示例性地，在一实施例中，连接管30与不锈钢主管10为分体结构。如此，不锈钢主管10通过连接管30与支管20连接且连通，连接管30使得不锈钢主管10无需缩管就能与支管20紧密连接。具体的，连接管30的一端与不锈钢主管10连接，连接管30的另一端形成连接孔321，连接孔321的孔径小于不锈钢主管10的内径，支管20与连接管30形成连接孔321的一端连接。
需要说明的是，“接管30与不锈钢主管10为分体结构”指连接管30和不锈钢主管10可各自独立，分开成型，进而可以通过卡接、焊接、铆接等方式相连。
示例性地，在该实施例中，连接管30通过拉伸工艺形成，并且连接管30拉伸后形成连接孔321。如此，拉伸工艺的加工速度快，加工成本低，拉伸形成的连接管30的表面光滑，曲线平缓，能够减少介质流动的阻力。
在另一实施例中，连接管30与不锈钢主管10为一体结构。如图6至图7所示，不锈钢主管10的一端通过行程较小的旋压一体形成连接管30，且连接管30旋压后形成连接孔321，连接孔321的孔径小于不锈钢主管10的内径，且连接孔321的孔径大于支管20的内径，为实现与支管20的连接，支管20的一端设置有扩径段21，至少部分扩径段21位于连接孔321，扩径段21与连接管30连接，如此，连接管30通过不锈钢主管10自身旋压形成，无需额外增设结构，降低了耗材成本，简化了装配步骤，且连接管30与不锈钢主管10的一致性更好，而且由于支管20的一端设置有扩径段21，所以不锈钢主管10的旋压幅度无需过大，就能够与支管20实现连接，解决了不锈钢材质硬度较高，难以进行程度较大的缩口的问题。
需要说明的是，“接管30与不锈钢主管10为一体结构”指连接管30和不锈钢主管10是通过一体成型的方式形成的整体结构。
具体地，请参见图7，定义连接孔321的直径为R2，定义不锈钢主管10的直径为R1，R1和R2满足：0.6R1≤R2＜R1。如此，合理规定了不锈钢主管10的旋压范围，避免过度旋压后导致连接孔321的直径R2过小，而损伤不锈钢主管10。
示例性地，0.6R1仅为不锈钢主管10旋压后的极限值，连接孔321的直径R2还可以是0.7R1、0.8R1或0.9R1等，而不限于上述的0.6R1。
连接管30包括互相连通的第一管段31和第二管段32，第一管段31与不锈钢主管10连接，第二管段32设于第一管段31的端面，且连接孔321形成于第二管段32上，支管20与第二管段32连接，并且与不锈钢主管10连通，连接孔321的孔径小于不锈钢主管10的内径。如此，第一管段31用于和不锈钢主管10连接，第二管段32用于和支管20连接，因此在第二管段32上形成连接孔321时，第一管段31与不锈钢主管10的连接不会受到影响，保证了连接管30与不锈钢主管10的稳定连接。第二管段32还增加了连接管30与支管20连接的接触面积，从而提高了连接管30与支管20之间的连接强度。
连接管30的具体结构和布设方式有多种实施例，在此分别详细阐述。
实施例一
请参见图1至图2，第一管段31套设于不锈钢主管10的外壁，第二管段32连接于第 一管段31远离不锈钢主管10的一侧，并位于第一管段31外，且第二管段32朝向第一管段31远离不锈钢主管10的方向延伸。如此，第一管段31套设于不锈钢主管10外，因此第一管段31的内壁与不锈钢主管10的端面会自然形成干涉限位，使连接管30稳定地卡接于不锈钢主管10外，而且第二管段32位于第一管段31以及不锈钢主管10外，便于支管20与第二管段32的连接，方便支管20与第二管段32之间进行焊接等连接工艺。
在本实施例中，支管20可以套设于第二管段32的外周壁或者插接于连接孔321内。支管20的一端可以设置有限位件(图未示)，在连接管30与支管20连接时，限位件能够与连接管30形成限位配合，如此能够使连接管30和支管20之间的相对位置固定。限位件可以根据不同的情况设置为缩口、定位点或者定位环中的任意一种。
示例性地，当支管20套设于第二管段32的外周壁时，支管20的内壁可以设置定位点或者定位环，定位点和定位环可以限制支管20朝向第二管段32的移动，防止第二管段32过度伸入支管20中，或者支管20可以直接通过第一管段31用于连接第二管段32的过渡部313限位。
具体地，支管20的内壁设置有至少一个凸起，凸起即为定位点。凸起的数量可以根据工作需求相应增加。支管20的内壁也可以设置卡接环，例如卡簧或橡胶环，以此作为定位环。
当然，在其他实施例中，定位点和定位环还可以为其他结构，只需要能够与第二管段32卡接限位即可。
支管20也可以插接于连接孔321内，如此，支管20与连接孔321的接触面积更大，且支管20与连接管30的连接更加方便。在本实施例中，支管20可以设置缩口作为限位件，缩口的外径小于连接孔321的孔径，因此缩口可以伸入连接孔321中，而支管20中正常外径的部分与缩口之间会自然形成台阶，台阶会与第二管段32抵接，从而限制支管20继续伸入连接孔321中。
进一步地，第一管段31包括本体部312和过渡部313，本体部312与过渡部313连接，过渡部313位于本体部312和第二管段32之间，且朝向第二管段32倾斜，如此，过渡部313能够对介质起到导向作用，介质从不锈钢主管10中流向第一管段31，然后被过渡部313平缓地引导至第二管段32，最后流入支管20中，减少了介质的紊流。
实施例二
请参见图3，第一管段31套设于不锈钢主管10的外壁，第二管段32位于第一管段31内，并且朝向不锈钢主管10的方向延伸。如此，第一管段31套设于不锈钢主管10外，因此第一管段31的内壁与不锈钢主管10的端面会自然形成干涉限位，使连接管30稳定 地卡接于不锈钢主管10外。第二管段32不会占用不锈钢主管10外侧的空间，节省空间。当然，作为其他实施方式，第二管段32也可以位于第一管段31外，并且朝背离不锈钢主管10的方向延伸。
实施例三
请参见图4，第一管段31插接于不锈钢主管10内，且第一管段31与不锈钢主管10焊接连接，第二管段32位于第一管段31内，并且朝向不锈钢主管10的方向延伸，如此，第一管段31和第二管段32均位于不锈钢主管10内，节省了连接管30所占用的空间，而且第一管段31与不锈钢主管10内壁的接触面积更大，提高了连接强度。同样的，作为其他实施方式，第二管段32也可以位于第一管段31外，并且朝背离不锈钢主管10的方向延伸。
实施例四
请参见图5，第一管段31远离第二管段32的一端的外周壁上凸设有翻边311，第一管段31插接于不锈钢主管10内，翻边311抵接于不锈钢主管10的端面，翻边311和/或第一管段31与不锈钢主管10焊接连接。如此，翻边311与不锈钢主管10的端面形成抵接限位，避免连接管30过度进入不锈钢主管10中。
在本实施例中，第一管段31插接于不锈钢主管10中，第二管段32与第一管段31连接并位于第一管段31内，且朝向背离不锈钢主管10的方向延伸。当然，第二管段32也可以位于第一管段31外并朝远离支管20的方向延伸。连接管30的布设方式及其技术效果与实施例三类似，在此不再赘述。支管20插接于连接孔321内，第二管段32与支管20焊接连接。
在上述实施例中，第一管段31可以与不锈钢主管10焊接连接，以使所述第一管段31稳定地连接于不锈钢主管10内。当然，可以理解地，在其他实施例中，第一管段31和不锈钢主管10还可以通过过盈卡接、粘接等其他连接方式，而并不限于焊接。
实施例五
请参见图6至图7，不锈钢主管10通过旋压一体形成连接管30，第一管段31与不锈钢主管10连接，第二管段32连接于第一管段31远离不锈钢主管10的一端，并且背向不锈钢主管10延伸。如此，便于对不锈钢主管10进行旋压加工，且与支管20的装配更加便捷，与支管20连接时的焊接等加固工艺也能有更大的操作空间。
优选地，支管20插接于第二管段32内，并且支管20靠近第二管段32的一端具有扩径段21，扩径段21的外壁抵接于第二管段32的内壁。如此，由于支管20具有扩径段21，并且扩径段21位于第二管段32内，所以不锈钢主管10的旋压程度较小也同样可以与支 管20实现连接，降低了工艺难度。
此外，支管20优选采用铜管，铜管的韧性好，便于进行胀管或缩口工艺，耐用性高。在其他实施例中，支管20也可以采用铝合金或铜镍合金等。
相较于相关技术，本申请通过增设连接管30，不锈钢主管10通过连接管30与支管20连接且连通，连接管30使得不锈钢主管10无需进行大幅度缩管就能与支管20紧密连接，而且连接管30通过拉伸工艺形成，其加工速度快，加工成本低，拉伸形成的连接管30的表面光滑，曲线平缓，能够减少介质流动的阻力。不锈钢主管10的一端通过旋压形成连接管30，连接管30通过不锈钢主管10自身旋压形成，无需额外增设结构，降低了耗材成本，简化了装配步骤，且连接管30与不锈钢主管10的一致性更好，支管20的一端设置有扩径段21，扩径段21与连接管30连接，如此，不锈钢主管10的旋压幅度无需过大，就能够与支管20实现连接，解决了不锈钢材质硬度较高，难以进行程度较大的缩口的问题。
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，本申请的专利保护范围应以所附权利要求为准。
