Process for manufacturing finely structured bodies such as heat exchangers |
摘要 |
A method of producing a finely structured body which includes a plurality of stacked, cut sections of foil at least one of which is provided with grooves in a selected groove direction on at least one surface thereof, and which has a plurality of closely juxtaposed, channel-like perforations with high shape accuracy, true dimensions and high surface quality. The method includes: a. providing a vacuum clamping means comprised of a ground, sintered metal plate which is connected to a vacuum source and which is positioned on a work table which is movable in two mutually perpendicular directions X and Y; b. positioning a machinable foil on the ground, sintered metal plate and clamping the machinable foil thereto by applying an effective amount of vacuum; c. cutting a plurality of parallel grooves into the surface of the machinable foil by means of at least one shaping diamond positioned on a cutting spindle and adjustable in a direction Z, each groove of the plurality of grooves having a groove length, a groove width, and a cross-sectional shape that is constant over the groove length and freely selectable; d. cutting the grooved machinable foil into cut sections having selected lengths and widths; and e. stacking the cut sections, wherein the plurality of grooves have a form precision such that, for groove lengths of more than 1000 mu m, the groove width has an accuracy of about +1 mu m for land widths which equal or exceed about 15 mu m.
