Aluminum clad copper tube in finned tube heat exchanger

The aluminum clad copper tube was investigated to replace copper tube as finned tube heat exchanger. The heat transfer performance and cost of three types of finned tube heat exchangers adopting copper tube, subcooled portion with aluminum clad copper tube and all aluminum clad copper tube with OD 7.94mm diameter were compared. The experimental results show that with the same wind speed and air volume, the capacity of the heat exchanger with aluminum clad copper tube, and lower than that of the heat exchanger with copper tube. meanwhile, the capacity of the heat exchanger with aluminum clad copper tube in subcooled portion in the refrigerant side is 8.885KW, which is 1.24% higher than that of the heat changer with all aluminum clad copper tube can be reduced 29% compared with copper tube. In summary, the heat exchanger with aluminum clad copper tube in subcooled portion can replace the heat exchanger with copper tube in the condenser of air conditioning, which can reduce cost and meet with the performance of heat exchangers.
