HEAT-EXCHANGE TUBE

摘要

On the transverse horizontal ribs (2) of a heat-exchange tube (1) are arranged essentially triangular turbulators (3) which make an angle alpha with the longitudinal plane of the tube (RLE) which passes through the axis of the tube (RA) and extends parallel to the direction of fluid flow (FSR). The turbulators (3) are punched out in the plane of the ribs and then bent through approximately 90 DEG . They have edges (4) inclined at an angle to the direction of fluid flow (FSR) and to the heat-exchange tube (1). Longitudinal turbulences (5) are thereby generated behind the turbulators (3), which at this point mix the limiting layers and improve the heat transmission.
