This combination aims to make full use of the respective advantages of copper pipes and aluminum pipes to meet the comprehensive needs of air-conditioning systems in terms of refrigeration, heat transfer, corrosion resistance and cost.

[0003] A Chinese patent discloses a copper-connected aluminum tube for air conditioner refrigeration tubes (publication number CN106403402A). This patented technology has three connecting tubes, which can make the connection between adjacent refrigeration tubes in the second connecting tube body, minimizing leakage points at the connection. In addition, the first connecting tube body and the second connecting tube body are curved tubes, ensuring better connection between the connecting tube and the refrigeration tube, which not only improves product quality but also facilitates the assembly of refrigeration equipment.

For example, the aforementioned reference document employs a multiple-section connection method. In actual use, when copper-to-aluminum tubes are connected in multiple sections, the sealing at the joints is poor, easily affecting normal use. Therefore, those skilled in the art have provided a copper-to-aluminum tube connection mechanism for air conditioner refrigeration tubes to address the issues raised in the aforementioned background art.

[0007] Preferably, one end of the positioning tube is embedded in the interior of the first connecting tube, and one end of the fixing tube is in contact with one end of the first connecting tube.

[0008] Preferably, an external thread is provided on the outside of the positioning tube near the fixing tube, and an internal thread that screws with the external thread is provided on the inside of the first connecting tube.

[0009] Preferably, a fixing groove is further provided on the outside of the positioning tube, a sealing ring is sleeved inside the fixing groove, and the outer surface of the sealing ring contacts the inner wall of the first connecting tube.

[0010] Preferably, the thermal insulation layer is made of EPE material.

[0011] Preferably, the second reinforcing plate is arranged perpendicular to the first reinforcing plate, and the outer surfaces of the second reinforcing plate and the first reinforcing plate are in contact with the inner side of the first connecting pipe.
