A heat exchanging device of the present invention includes two fluid compressing means respectively mounted on the centers of both sides of a partition, each for feeding a respective fluid under pressure. A plurality of passageways adjoin each other around the fluid compressing means, and each faces the associated fluid compressing means at one end while facing the outside of the partition at the other end. The passageways protrude from both sides of the partition. Among the passageways, either the odd passageways or the even passageways are open on the front side of the partition at both ends while the other passageways are open on the rear side of said same at both ends. Two fluids of different temperatures respectively compressed by the fluid compressing means are respectively fed under pressure from one ends to the other ends of the odd passageways and the even passageways while contacting each other with the intermediary of the side walls of the passageways to thereby exchange heat.
