Abstract (en)
A heat exchange unit (1) includes first and second plates (10,20), which is identical to each other in configuration in a peripheral area (50) thereof, but different from each other in a central irregularity pattern section (30,40). The irregularity pattern section (30,40) has a projection-recess pattern on its surface and a recess-projection pattern corresponding thereto on another surface. These patterns are different from each other in configuration. The projection-recess pattern of the first plate (10) has a reverse relationship in projections and recesses to the projection-recess pattern of the second plate (20) so as to be symmetrical to each other. The first and second plates (10,20) are placed alternately one upon another so that the peripheral areas (50) of the first and second plates (10,20) are directed to a same direction and projections of the irregularity pattern section (30) of the first plate (10) come, on peaks thereof, into contact with projections of the irregularity pattern section (40) of the second plate (20).
