Abstract (en)

[origin: EP0503080A1] In a laminated heat exchanger wherein partitions are provided in a plate (32) on a primary side and a plate (33) on a secondary side to form channels therein, and a plurality of the plates (32) on the primary side and the plates (33) on the secondary side are laminated one upon another with respective seal plates (3) therebetween, each of the partitions (35) of the plates (33) on the secondary side are located at positions opposed to each of the channels (11) of the plates (32) on the primary side and each of the partitions (34) of the plates (32) of the primary side are located at positions opposed to each of the channels (17) of the plates (33) on the secondary side, thereby preventing the seal plates (3) from being deformed even if pressure of the coolant flowing through the channels becomes nonuniform. Furthermore, sides of the plates (32) on the primary side, the plates (33) on the secondary side and the seal plates (3) are formed into shapes different from one another, thereby making it easy to identify falling-off of a plate. <IMAGE>
