Tube heat exchanger with optimized thermo-hydraulic characteristics

摘要

A tube heat exchanger (1) comprising at least a tube extending along a certain axial direction (A), each tube being provided with heat exchange fins (4) spaced apart from one another along said axial direction (A) and extending radially from said tube, each fin (4) being relief structured to form a groove/rib (5) arranged at a first distance from the tube and dimples (6) arranged in at least one line at a second distance from said tube, said second distance being greater than said first distance.
