HEAT TRANSFER FIN AND FIN-TUBE HEAT EXCHANGER
摘要:
A fin (3) of a fin-tube heat exchanger (1) has protuberances (5) each disposed between two adjacent heat transfer tubes (2, 2) and holes 8 (cut-outs) each formed upstream of the protuberances (5). Each of the protuberances (5) has, as an upstream portion adjacent to the hole (8), a wing portion (6) tapering toward an upstream side.
