Abstract
A heat exchanger having two parallel manifold ducts that communicate with one another through a matrix of several rows of heat exchange tubes, in which a number of sheet metal tray members placed on top of one another form the rows of tubes. Two complementary sheet metal tray members are joined to one another each having a number of parallel longitudinal slots that are interrupted by webs. The heat exchange tubes are formed by opposed trough-shaped portions formed between the slots of the joined complementary tray members.
