PROBLEM TO BE SOLVED: To provide a stacked heat exchanger allowing fluid passages to be formed with simple constitution without forming grooves for forming the fluid passages, in plates by plastic working or etching. SOLUTION: This stacked heat exchanger 1 is formed by stacking a plurality of flat plates 2 at predetermined spaces, and forming first fluid passages 3 through which a first refrigerant flows, and second fluid passages 4 through which a second refrigerant heat-exchanged with the first refrigerant flows, alternately between the respective flat plates 2. The first fluid passages 3 and second fluid passages 4 are formed of cavity parts formed between the wire rods 5, 5 of round cross section fixed between the flat plates 2 by brazing at a predetermined pitch. The micro channel type stacked heat exchanger 1 can be easily manufactured without grooving the flat plates 2 by forming the fluid passages using the wire rods 5, 5. COPYRIGHT: (C)2007,JPO&INPIT
