Abstract
A heat exchanger includes ribs mounted transversely of the axis of the tube and uniformly spaced therealong. Each rib includes a plate with corrugations oriented along the flow of the fluid washing the tube. The ribs adjoin one another, their corrugations having lateral slits, the wall portions between these slits being offset relative to one another to provide passages for the flow of the fluid. Owing to this structure the thickness of the boundary layer at each one of said portions is reduced, and the effectiveness of heat exchange is stepped up. Furthermore, a heat exchanger with the disclosed ribs is considerably more compact and needs less metal for its construction, as compared with known heat exchangers.
