在本实施例中，室内机10具有室内换热器，室外机具有室外换热器，连接组件连通室内换热器与室外换热器，以实现冷媒在室内换热器与室外换热器之间的循环流动，形成冷媒换热回路。第一冷媒管20通过卡套30与其它冷媒管20或接头固定连通，其中，第一冷媒管20插接于卡套30的一端，其它冷媒管20或接头插接于卡套30的另一端。卡套30整体呈筒状，可为与圆形冷媒管20对应的圆筒，以增加与第一冷媒管20的配合面积，提高配合强度。配合段31在卡套30上的比例不做限制，只需满足可供第一冷媒管20插接即可。起伏部311凸设于配合段31的外周壁，起伏部311的具体形式可为环形，也可为凸点形，在此不做限制。起伏部311可与卡套30一体成型设置，也可另外连接于卡套30，在此不做限制。第一冷媒管20插接于卡套30后，可利用工装向起伏部311施力，以使起伏部311沿径向朝内加压配合段31，从而将配合段31压固于第一冷媒管20，以实现卡套30与第一冷媒管20的紧配合。可实现连接的硬密封，提升密封效果。由于起伏部311凸出于卡套30的外表面，因此利于受力，提高工装的施力效果，从而可降低对第一冷媒管20的压固难度，提高第一冷媒管20与卡套30的装配效率。卡套30的外表面可设置热塑性材质的保护层，如EVA，以提高卡套30的结构稳定性。
本申请空调器在卡套30配合段31的外表面设置起伏部311，从而在冷媒管20插接于卡套30后，通过工装沿径向压固起伏部311，即可使配合段31的内表面压紧冷媒管20，从而实现冷媒管20与卡套30的固定配合，降低了装配难度，提高装配效率。
具体地，所述起伏部311沿所述卡套30的周向延伸，以形成环状结构，从而在周向上的各个位置均能有效受力，并且还能使卡套30周向上各个位置的受力更加均匀，提高装配过程的稳定性。在实际应用中，卡套30可采用铜材料制成，以提高结构强度；起伏部311可与卡套30一体注塑成型，以降低生产成本。起伏部311的数量可为一个，也可为多个，起伏部311的数量为多个时，多个起伏部311沿卡套30的轴向间隔设置。
如图2所示，所述卡套30内设有密封圈40，所述第一冷媒管20通过所述密封圈40与所述卡套30密封配合。在本实施例中，密封圈40位于配合段31处并沿卡套30的周向延伸，第一冷媒管20插接于配合段31后，密封圈40环设于第一冷媒管20，从而可有效密封第一冷媒管20与卡套30之前的间隙，防止冷媒泄露。密封圈40可采用弹性材料制成，如橡胶，以通过弹性变形使第一冷媒管20与卡套30的配合过程更加顺利。具体地，密封圈40的材质可为CR、HNBR、PTFE。第一冷媒管20插接于卡套30的过程中，密封圈40会被第一冷媒管20挤压变形，配合完成后，密封圈40会膨胀恢复，膨胀过程中会填充第一冷媒管20与卡套30之间的间隙，以提高密封性。
如图2所示，所述起伏部311位于所述密封圈40的周侧。在本实施例中，密封圈40连接于卡套30的内周壁，起伏部311连接于卡套30的外周壁，起伏部311位于密封圈40径向上的外侧，从而通过工装压接起伏部311时，密封圈40位于最大受力的位置，如此，既可将密封圈40紧密压固于第一冷媒管20，以进一步提高密封性，又可避免第一冷媒管20的外壁和卡套30的内壁在受力最大的位置直接接触，以防止第一冷媒管20受力变形损坏，由此，可提高连接组件的结构稳定性。
如图2所示，所述卡套30的内壁面开设有沿所述第一冷媒管20的周向延伸的密封槽32，所述密封圈40嵌设于所述密封槽32。在本实施例中，密封槽32沿配合段31的周向延伸，密封圈40嵌设于密封槽32，以避免脱离卡套30，提高密封稳定性。结合上述起伏部311位于密封圈40周侧的实施例，密封槽32可开设于对应起伏部311的位置，由此既可将密封圈40定位于起伏部311径向上内侧的位置，又可避免卡套30在起伏部311位置的应力集中，以提高卡套30的结构稳定性。密封槽32的数量可为一个，也可为多个，若密封槽32的数量为多个，则多个密封槽32沿卡套30的轴向间隔设置。
如图2所示，所述卡套30的内壁凸设有限位部33，所述第一冷媒管20的端部抵接于所述限位部33，以将所述第一冷媒管20限位于所述配合段31。在本实施例中，限位部33的具体形式不做限制，可为凸点，也可为凸条，在此不做限制，只需满足凸设于卡套30的内壁面即可。限位部33凸设于配合段31的内端，从而可将第一冷媒管20限位于配合段31处，以限制第一冷媒管20的插接深度。具体地，限位部33可沿卡套30的周向延伸以呈环形设置，从而可增加与第一冷媒管20的抵接面积，提高限位稳定性。具体地，限位部33的内径和第一冷媒管20的内径比值可设置为0.8-0.99。
所述第一冷媒管20的外表面设有树脂层，树脂层可涂布于第一冷媒管20。在安装空调器时，需要将第一冷媒管20弯曲以适应安装环境，树脂层可在弯曲过程中支撑第一冷媒管20，避免第一冷媒管20折断或干瘪堵塞，以提高第一冷媒管20的安装稳定性。具体地，所述树脂层的厚度不小于0.02mm，且不超出0.08mm，以在保护第一冷媒管20的同时，保持第一冷媒管20的可弯曲性能，树脂层还能为第一冷媒管20提供支撑，以使第一冷媒管20能自由盘绕。在实际应用中，所述树脂层的外表面还设有铝箔层。铝箔层可包覆于第一冷媒管20，用以防止第一冷媒管20和树脂层因环境影响，如紫外线，而老化，从而可提高第一冷媒管20的结构稳定性。
所述第一冷媒管20的外表面还设有防老化层、防凝露层、保温层和防刮花层中的一种或多种。在本实施例中，防老化层可防止第一冷媒管20被腐蚀，以延长第一冷媒管20的工作寿命；防凝露层可防止第一冷媒管20表面形成凝露而滴水；保温层可减少冷媒通过第一冷媒管20散失的热量；防刮花层可防止第一冷媒管20被刮花，以保持第一冷媒管20的外观。在实际应用中，第一冷媒管20的外表面可同时设有树脂层、防老化层、防凝露层、保温层和防刮花层；其中，树脂层设于最内层，防老化层设于最外侧层，以使防老化层能同时保护树脂层，提高树脂层的稳定性。具体地，第一冷媒管20所设置的保护层材料可包括PVC、EVA、PE、PP、TPU等，材料件的组合方式包括套设、胶黏、镀层、喷涂等。
如图3所示，所述连接组件还包括第二冷媒管5020及第三冷媒管20，所述第二冷媒管5020与所述室内机10焊接固定、卡接固定或过盈配合固定，所述第三冷媒管20与所述室外机焊接固定、卡接固定或过盈配合固定。在本实施例中，第二冷媒管5020与室内机10的室内换热器通过焊接固定、卡接固定、扣压卡紧或过盈配合等方式固定连通，由于室内换热器具有进口和出口，因此第二冷媒管5020的数量为两个并分别与进口和出口连通，两第二冷媒管5020均与室内换热器固定连接。第三冷媒管20与室外机的室外换热器通过焊接固定、卡接固定、扣压卡紧或过盈配合等方式固定连通，由于室外换热器具有进口和出口，因此第三冷媒管20的数量为两个并分别与进口和出口连通，两第三冷媒管20均与室外换热器固定连接。第二冷媒管5020与室内机10固定连通，第三冷媒管20与室外机固定连通，从而在安装空调器时，只需连通第二冷媒管5020与第三冷媒管20即可，无需再接通冷媒管20与室内机10或室外机，由此，可提高空调器的安装效率。
