Abstract (en)
[origin: EP1318371A2] The heat transfer surface (3), on a plate or tube body (4), has a galvanized projecting micro-structure extending from the base surface (3a) with a minimum height of 10 mu m. The base surface is covered with projections (6), wholly or partially, as pin-shaped micro-structures. The longitudinal axes (6c) of the micro-pins are either at right angles to the surface or they are pitched at an angle of 30-90 degrees to the surface. The micro-pins have a thickness (d) of 0.2-100.0 mu m, with a pin density of 10<2>-10<8> per cm<2>. The structures are galvanized on to the surface using a polymer membrane with micro-pores.
