摘要

A numerical study has been performed to suggest the 1 -row inclined offset strip fin-tube heat exchanger with grooves which has a similar performance to the 2-row plain offset strip fin-tube heat exchanger and to predict their air-side local flow and heat transfer characteristics. The results indicated that the reversed geometry of the main slit between the front half and the rear half of the heat exchanger caused more pressure drop than the identical one. In addition, the heat transfer rate of the 1-row A-type inclined offset strip fin-tube heat exchanger with grooves reached about 96% ~ 99% of the 2-row offset strip fm-tube heat exchanger, and the fan power representing the energy consumption rate was reduced to 90% ~ 99%.
