Abstract
A heat exchanger and a heat exchanger core are disclosed. The heat exchanger core is formed from a strip of synthetic resin molded into multiple panels which are accordion folded to form the heat exchanger core. One embodiment is a counterflow core in which sides of each panel parallel to the longitudinal axis of the strip are divided to form a closed portion and an open portion. The opposite longitudinal sides are similarly formed but the portions are reversed. The sides of each panel perpendicular to the longitudinal axis of the strip are closed either by a hinge formed in the strip or by panel borders abutting each other. A second embodiment discloses a strip also formed into multiple panels and accordion folded. However, every second hinge has an opening so that when folded, a cross flow core is created. Both cores are mated with appropriately designed molded plastic housings to form effective but simple and economical heat exchangers.
