A heat exchanger comprises an elongated plate folded in corrugated fashion and defining a stack of a number of laminated air passages defined by spacer parallel plane heat transfer faces or plates connected alternately along opposite side edges by narrow partition plates. In alternate air passages, spacer plates are disposed having such a wavy or corrugated configuration as to conduct a first current of air flowing into such alternate passages from one open end thereof to flow out from an open side portion thereof opposite the corresponding partition plate. In the remainder of the air passages are disposed spacer plates having such a wavy or corrugated configuration as to conduct a second current of air flowing into such passages from the open ends thereof, opposite those into which the first air current flows, to flow out from open side portions thereof opposite those out from which the first current flows.

A total heat exchanger comprising: a stack of plane parallel spaced heat-exchange plates, of material having heat conductivity and moisture permeability, integrally connected alternately along the entire length of their opposite side edges by narrow plane partition platess of the same material to define alternate passages having inlet ends and open side portions, for first and second counter-currents of air, respectively, flowing into the inlet ends of said passages from opposite sides of said exchanger, all of said plates being defined by a folded single strip of said material; first sets of corrugated spacer plates disposed in alternate of said passages so as to conduct a portion of the first air current flowing into each of said alternate passages, from the corresponding inlet end thereof, to flow out of said open side portions of said alternate passages opposite the corresponding partition plate thereof; and second sets of corrugated spacer plates disposed in the remaining of said passages so as to conduct a portion of the second air current flowing into each of said remaining passages, from the corresponding inlet end thereof opposite said inlet ends of said alternate passages, to flow out of said open side portions of said remaining passages opposite the corresponding partition plate thereof; said first and second sets of spacer plates each comprising at least two separate spacer plates arranged at a position of a point of symmetry with respect to the at least two separate corrugated spacer plates of adjacent passages.
