Abstract
Abstract In a plate heat exchanger comprising a plurality of plates (10, 15) placed together to define heat exchange passages (18, 19) between pairs of adjacent plates, the plates being provided with turbulence generating corrugations which on adjacent plates intersect to define supporting areas at which the plates abut each other, at least one plate (10) of one or more pairs of adjacent plates has recessed supporting areas (13) whereby the volume of the passage (18) defined between said plates is reduced.
