An evaporative plate-type heat exchanger is provided having a plurality of alternating first plates and second plates positioned in side-by side relationship to form a top surface, a bottom surface, a front surface and a rear surface. The first and second plates form a plurality of dry air flow passages, between first faces of the first plates and first faces of adjacent second plates, that are in communication with dry air flow inlet openings and dry air flow outlet openings formed in the front surface. The first and second plates form a plurality of dry air flow passages, between second faces of the first plates and second faces of adjacent second plates, that are in communication with wet air flow inlet openings formed in the bottom surface and with wet air flow outlet openings formed in the rear surface. A method of forming the plate-type heat exchanger includes forming alternating first plates and second plates in a continuous sheet, and folding the continuous sheet in a fan fold arrangement.
