PROBLEM TO BE SOLVED: To permit the setting of respective heat transfer plates at specified positions and laminating them without being affected by a gap between the outer peripheral parts of neighboring heat transfer plates by a method wherein the heat transfer plates are provided with a notch for positioning at the outer rim part thereof. SOLUTION: Positioning notches 14, 14 are provided at total two places at the central part of the upper rim side of the outer rim pant or the flat part of a heat transfer plate 11. Then, the heat transfer plates 11 are laminated employing a laminating jig 16 whereby respective heat transfer plates 11, 11,... can be set at specified positions and laminated without being affected by a gap between the skirt part 11b, 11b of the neighboring heat transfer plates 11, 11. In this case, the laminating jig 16 is constituted so that two pieces of positioning pins 16b, 16b, to which the notches 14 for positioning the heat transfer plates 11 are fit tightly, are established uprightly in parallel on the supporting table 16a of the same. |
