FIN-TUBE HEAT EXCHANGER

摘要

A fin-tube heat exchanger is provided to modify shape of fins to increase contact areas for tubes, thereby improving heat exchange efficiency between the tubes and ambient air. A fin-tube heat exchanger includes fins(102) in the shape of waveform and tubes(101) in a corrugation shape. The tubes are coupled with curved surfaces of the fins in the waveform, so that linear or surface contact rather than point contact is realized between the tubes and the fins, increasing heat transmission areas between the tubes and the fins.
