PCT No. PCT/US96/15447 Sec. 371 Date Mar. 9, 1998 Sec. 102(e) Date Mar. 9, 1998 PCT Filed Sep. 26, 1996 PCT Pub. No. WO97/12191 PCT Pub. Date Apr. 3, 1997A heat exchanger (10) including a heat exchanger conduit and fins arranged on the conduit tubes (12, 12') to further heat transfer between the external fluid flowing over the fins (22, 22') and the fluid flowing within the conduit. The fins (22, 22') include a row of apertures through which tubes (12, 12') of the heat exchanger conduit extend. The leading (4, 6) and trailing (48) edges of the fins (22, 22') are contoured to substantially conform to isotherms around the circulating fluid flowing within the tubes (12, 12'). To achieve this edge configuration while also allowing for a dense packing of fins and tubes in a multi-row heat exchanger, the leading and trailing edges are wave-shaped such that adjacent fins can interfit together. |
