(54) | BASE PANEL MATERIAL FOR USE AS HEAT EXCHANGE PLATE AND METHOD FOR MANUFACTURING SUCH BASE PANEL MATERIAL |
(57) The object of the invention is to provide: a plate for a heat-exchanging plate that
allows a liquid film generated during the operation of a heat exchanger to be efficiently
discharged, allows irregularities to be formed such that the thickness of the liquid
film is reduced, and allows enhancing heat-transfer performance without collapse of
the irregularities; and a method for producing the plate. A plate (1) for a heat-exchanging
plate is constituted by a metallic flat plate having fine irregularities formed on
a surface thereof, and is obtained through press working, which is implemented as
a post-process, of the flat plate. The irregularities include a plurality of projections
(2) formed at a predetermined spacing. The plurality of projections (2) include first
ridges (2a) disposed at an angle +θ with respect to the width direction of the plate
(1), and second ridges (2b) disposed at an angle -θ with respect to the width direction
of the plate (1). The projections (2) are formed into V-shapes by the first ridges
(2a) and the second ridges (2b).
