<P>PROBLEM TO BE SOLVED: To provide a laminated heat exchanger and a method for producing the same which can join adjacent passage pipes to each other in a state of where a gap dimension between the adjacent passage pipes is maintained constant without using a tool for maintaining the gap dimension constant. <P>SOLUTION: A passage pipe 3 is provided with a projecting tube part 4 which is open and projects in a lamination direction of the passage pipes. A communication member 5 is formed by fitting the projecting tube parts 4 of the adjacent passage pipes 3 to each other. In a pair of the projecting tube parts 4 fitted to each other, a distal part 411 of one projecting tube part 41 is formed in a tapered shape decreasing in diameter toward the opening end, and a distal part 421 of the other projecting tube part 42 is formed in an enlarging shape increasing in diameter toward the opening end. At least a part of the outer surface of the distal part 411 of the one projecting tube part 41 is brought into contact with the inner surface of the distal part 421 of the other projecting tube part 42. <P>COPYRIGHT: (C)2012,JPO&INPIT |
