伸ばされて変形を生じる。By the way, in this type of plate heat exchanger, since the fluid in the passage hole (2) of the plate (1) is under pressure during heat exchange, the corners of the plate (1) are As shown in FIG. 9, the portion receives a fluid pressure (indicated by an arrow a in the figure). Therefore, a tensile force (indicated by an arrow b in the figure) due to the fluid pressure (a) is generated in the plate outer peripheral portion (5) at the corner portion of the plate (1). When this tensile force (b) becomes larger than the material deformation strength, the inclined sidewalls (4) of the gasket groove (4) of the outer peripheral beads (6) (6b) formed on the plate outer peripheral portion (5) of the corner portion of the plate (1) ( 6a) is stretched like a folding screen and deformed.

When it occurs, the fluid of high fluid pressure (c) pushes the inclined side wall (6a) of the outer bead (6) (6b) to the fluid side of the low fluid pressure (d), and the outer bead (6) of the plate (1). ) (6b) receives the force to spread the outer contact (indicated by arrow e in the figure). When the force (e) for pushing the outer contact of the outer peripheral beads (6) (6b) of the plate (1) becomes larger than the material deformation strength, the outer peripheral beads (6) (6b).
The slanted side wall (6a) is deformed.
