PROBLEM TO BE SOLVED: To elongate the flow passage of each fluid as far as possible and to promote heat exchange in a stacked heat exchanger in which a first fluid and a second fluid alternately circulate by each plate and no inner fin is present between the plates.SOLUTION: First projections 11 and second projections 12 are arranged in a staggered pattern on a first plate 1 and a second plate 2, respectively. The layout positions of the projections on the plates are shifted to each other, the first fluid 3 circulates in a first flow passage 9 while meandering in an M-shaped pattern on a plane, and the second fluid 4 circulates in a second flow passage 10 while meandering in an M-shaped pattern on a plane. |
