Abstract (en)
[origin: US4789027A] The heat exchanger is formed of parallel rows of tubes and transverse ribs. The ribs have flat uncorrugated parts extending in zones about and along the rows of tubes as well as corrugated parts extending between the rows of tubes. The flat parts may be separated from the corrugated parts by stepped parts or fillers may be provided in the gaps between the uncorrugated parts. The gaps are to conduct a flow of medium in heat exchange relation to a flow of medium through the tubes. The crests and troughs of each corrugated part extend from the same plane adjacent a flat part and terminate in a similar plane at an adjacent flat part. Streamline-shaped inflow and outflow members aligned with the stepped part of the fin direct the flow of air.
