Abstract
This specification relates to a heat exchanger (10) of the type wherein a plurality of elongated plates (12) are laminated together to define a plurality of passageways (14) for movement of a fluid therethrough. Each of the passageways (14) are formed by inwardly facing surfaces of a pair of laminated plates (12--12) which define a central fluid conducting section (34) located between reservoir sections (32--32) at each end thereof. Adjacent of the passageways (14--14) have heat transfer fins (18--18) located therebetween. Reservoir sections (32--32) of adjacent ones of the passageways (14--14) are interconnected so that a fluid may flow therethrough. The improvement of this invention is made to the laminated plates and it includes a plurality of beads formed on each of the pair of laminated plates (12--12). The beads formed on each of the plates are of two distinct varieties. A first variety of the beads (40-1) extends above a surface of each laminated plate (12) and terminates in a relatively flat upper surface. A second of the variety of beads (40-2) extends above a surface of each laminated plate (12) and terminates in a bowed upper surface. The first and the second variety of beads (respectively 40-1 and 40-2) are so constructed and arranged that the first variety of beads (40-1 on one of the elongated plates (12) are in bonding contact with the second variety of beads (40-2) on the other of the pair of laminated plates (12) and vice-versa.
