Abstract (en)
[origin: ES8306864A1] An annular capillary structure is disclosed for tubes of heat exchangers. The capillary structure comprises a series of individual, smooth, rectilinear fibers arranged parallel to the axis of a tube. The fibers are regularly positioned in annular spaces along the inner wall of the tubes. Helical springs or a layer of spring wires urges the fibers into contact with the inner wall of the tube. According to a preferred method of making the structure, a layer of spring steel wires are coiled on a mandrel and a layer of fibers is laid longitudinally thereon. The layer pass through an extruder head and are introduced into the tubular element which has just been extruded.
