Abstract (en)
[origin: EP2757341A1] This original plate material for a heat exchanging plate (4) comprises a titanium flat plate material (1) having a minute recess and projections on the surface thereof, and the flat plate material (1) is press-worked to obtain the heat exchanging plate (4). The shape parameter (G1), defined as [height (µm) of the projections] x [width (µm) of the recess/pitch (µm) of adjacent projections], is 85 µm or less. Relating to this original plate material for a heat exchanging plate (4), the shape parameter (G2), defined as [height (µm) of the projections] x [width (µm) of the recess/pitch (µm) of adjacent projections/angle (deg) of the projections], is 0.94 µm/deg or less.
