RAW PLATE MATERIAL FOR HEAT-EXCHANGING PLATE, AND METHOD FOR FABRICATING RAW PLATE MATERIAL FOR HEAT-EXCHANGING PLATE |
摘要 |
Provided is an original plate material for a heat-exchanging plate fabricated by press working, and also provided is a method for fabricating the original plate material. An original 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 original 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). |
