Abstract
A heat transfer surface for use in conjunction with a heat exchanger is disclosed. The heat transfer surface a corrugated member where rows of corrugations that are offset relative to each other forming at least an alternating series of first and second rows or first, second and third rows. In some embodiments the heat transfer surface includes a heat transfer enhancement feature disposed within individual corrugations of the corrugated member to provide a more turbulent or tortuous fluid flow path through the heat transfer surface. In some example embodiments the heat transfer enhancement feature is a ridge disposed in the planar portions of at least some of the rows of corrugations. In other example embodiments the planar fin portions are porous fin surfaces. In other embodiments, the corrugated member cooperates with heat transfer enhancement features in the form of triangular protuberances disposed on their inner surfaces of spaced apart plates.
