ABSTRACT:
A corrugated sheet formed from a thermoplastic polymer is disclosed. The sheet has a plurality of fluid flow passages through each corrugation. At least one slope, and preferably both slopes, of each corrugation has a plurality of slits in side-by-side arrangement extending through the sheet, with the fluid flow passages being formed by displacement of the thermoplastic polymer between each pair of slits relative to the thermoplastic polymer between the pairs of slits adjacent thereto. One example of use of the corrugated sheet is in a panel heat exchanger, to cause turbulence in fluid passing through the heat exchanger. The preferred thermoplastic polymer is polyamide.
