ABSTRACT:
A heat exchanger comprises a plurality of perforated and regularly corrugated heat transfer plates arranged in a ridge-to-ridge and furrow-to-furrow arrangement, so as to form primary fluid passages each consisting of alternate expanded sections and narrowed sections arranged along the direction of flow of a primary fluid, and a plurality of pipes for passing a secondary fluid therethrough, the pipes penetrating through and across the heat transfer plates. Oblique guide grooves are formed in the surfaces of each heat transfer plates to facilitate the downward flow of the condensate condensed over the surfaces of the heat transfer plates, the grooves being inclined closer to the vertical than to the horizontal to facilitate downward flow of any vapor condensed on the plates from the primary fluid whereby the heat transfer plates dry quickly for efficient heat exchange between the primary and secondary fluids.
