Title:
RAW PLATE MATERIAL FOR HEAT EXCHANGING PLATE, AND HEAT EXCHANGING PLATE USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/039214
Kind Code:
A1
Abstract:
This raw plate material for a heat exchanging plate (4) comprises a titanium flat plate (1) having minute depressions and projections on the surface thereof, and the flat plate (1) is press-worked to obtain the heat exchanging plate (4). The shape parameter (G1), defined as [height (µm) of the projections] × [width (µm) of the depressions/pitch (µm) of adjacent projections], is 85 µm or less. Relating to this raw plate material for a heat exchanging plate (4), the shape parameter (G2), defined as [height (µm) of the projections] × [width (µm) of the depressions/pitch (µm) of adjacent projections/angle (deg) of the projections], is 0.94 µm/deg or less.
