Abstract
A heat exchanger of the plate fin type having first fluid channels and second fluid channels arranged alternately and each separated from the adjacent channel by a flat metal plate. At least one of the first fluid channel and the second fluid channel is formed by a pair of adjacent flat metal plates and a spacer interposed between the flat plates. The spacer comprises a pair of side walls each joined to and interconnecting a pair of opposed edges of the two flat plates at each side thereof, a connecting wall interconnecting the two side walls, and fins provided on the connecting wall at an angle therewith and joined at their forward ends to the flat plate, the fins extending in parallel with the direction of flow of fluid through the fluid channel. The heat exchanger is fabricated by arranging plate plates, spacers, fins and spacer bars in layers and joining the parts together by brazing at the same time.
