PURPOSE:To obtain a heat exchanging plate which is easy to be manufactured and is of high efficiency, by laminating a pair of plates on which a number of discontinuous openings are punched so that each opening is partially communicated with each other, forming a continuous fluid passage between the plates. CONSTITUTION:A pair of base plates 1a and 1b, on the surfaces of which a certain number of discontinuous openings 2a-2n or 2a'-2n' are respectively punched, are made of material such as metal or synthetic resin, and the openings are formed by press-cutting or molding form. When the base plates 1a and 1b are laminated, each opening on the base plate 1a is partially overlapped communicatedly with one of the openings on another base plate 1b, forming a through passage. Openings 2a and 2n are provided to one base plate, the plate 1a for example, by cutting one edge of the plate, to provide an inlet 3a and an outlet 3b for fluid. With such an arrangement, a through passage 3 communicating from the inlet 3a to the outlet 3b passing through the openings 2a-2n and 2a'-2n' is formed between the base plates 1a and 1b. |
