[0017] See attached Figure 1~3 , The double-row pipeline air-conditioning heat exchanger of the present invention includes a fin 2 and a double-row condenser tube 1 passing through the inner cavity of the fin 2, a shunt tube 7 connected to the condenser tube 1 in the lower part of the fin 2, and a distributor 21 , And the connecting pipe 16 arranged at the bottom of the fin 2 to communicate with the condenser tube 1. The condenser tube 1, the shunt tube 7 and the communicating tube 16 all use copper tubes, and the distributor 21 is a flooded copper distributor.
[0018] The branch pipe 7 includes a first branch pipe 5, a second branch pipe 6 and a third branch pipe 8 which divide the refrigerant into three paths. The first branch pipe 5 and the first inflow port of the condenser pipe 1 in the upper part of the fin 2 4, the second branch pipe 6 communicates with the second inflow port 15 of the condenser tube 1 in the middle of the fin 2, and the third branch pipe 8 communicates ...
