WIPO Patent Application WO/2011/136278
Kind Code:
A1
Abstract:
Provided is a raw plate material for a heat-exchanging plate fabricated by press working, and also provided is a method for fabricating the raw plate material. A raw plate material (2) for a heat-exchanging plate (4) is a flat plate material (1) made of titanium on the surface of which convex parts and concave parts are formed, and the heat-exchanging plate (4) is then fabricated by press working the raw plate material (2). The convex parts (5) and the concave parts (6) are formed in a manner such that the shape parameter defined by (Rz × L/P) is 12 μm or less, where Rz (μm) denotes the height of the convex parts (5), L (μm) denotes the width of the concave parts (6), and P (μm) denotes the pitch between neighboring convex parts (5).
