A heat exchanger with enhanced spacing and sealing characteristics is formed by folding a continuous strip of material having a rectangular pattern stamped thereon. The pattern includes rectangles which constitute base walls and side walls with multiple tabs on the periphery of the strip which comprise wall tabs and bonding tabs respectively. The continuous strip when folded forms a series of alternatingly stacked air passageways, created by the union of each of the base walls, side walls and wall tabs on the periphery of the strip. The bonding tabs may form a seal with a base wall internally, or the bonding tabs may form a seal with another matching bonding tab externally of the created air passageways. The heat exchanger formed upon folding has a number of alternating air passageways which are of a sufficient width for effective transfer of thermal energy.
