PROBLEM TO BE SOLVED: To improve a heat exchanging efficiency more at a heat exchanger.SOLUTION: A heat exchanger comprises a plurality of plates to perform a heat exchanging operation between the first fluid and the second fluid. Each of the plates is corrugated in form in a specified interval with its outer surface being protruded in line manner toward outside in salient and provided with corrugation form in at least the outer surface. Then, a plurality of plates are arranged with a longitudinal direction at the salient protrusions of the plates being crossed at a right angle with a flowing direction of the second fluid. Further, the plurality of plates are arranged at a state in which outer surfaces of the adjoining plates to each other are kept under non-abutted state having a clearance and under non-opposing arrangement in which the top points of the salients protruded from opposing outer surfaces to each other of the adjoining plates being non-opposing relation along the arranging direction of the plates.SELECTED DRAWING: Figure 3 |
