Abstract

Finned-tube heat exchanger, particularly for combined cycle power plants and the like, comprising a plurality of finned tubes (1) arranged in rows and flow deflectors (3) positioned between successive rows of said finned tubes (1), adjacent to said tubes, the distinctive feature of which consists in the fact that at least certain of said deflectors (3) comprise a plurality of vortex-generating elements (4) laid out on the surface of said deflectors (3), designed to generate vortexes with axes that are substantially parallel to the direction of flow of a fluid conveyed externally to pass over said finned tubes (1).
