强化内螺纹铜管传热的试验研究及分析

Abstract

Abstract: We mainly studies the influence of the heat transfer performance of the tooth profile of internal thread copper tube in heat exchanger ‘s refrigerant side. The spiral angle is usually in the range of 10°to 30°the effect of spiral angle on the performance of heat exchanger was studied by increasing the spiral angle of spiral angle and the lager number of gear tooth. The trend of increasing the helix angle and gear tooth to the heat exchanger performance was analyzed by monomer test and the whole machine performance test. It lays a good the oretical foundation for thes further development of efficient copper tube.

Key words: Spiral angle, Finned tube heat exchanger, Internal thread copper tube, Heat transfer performance
