摘要

A condenser for air-conditioning systems, particularly for motor vehicles, comprising a group of tubes (14) secured to a pack of substantially flat fins (16) by means of mechanical expansion of the tubes (14) following their insertion in holes aligned in the fins (16). The tubes (14) have an oblong cross-section without any flat walls, with a ratio of between 2.5 and 3.75 between the maximum dimension (b) and the minimum dimension (a) of the cross-section, and a ratio of between 15 and 30 between the maximum dimension (b) of the cross-section and the thickness (s) of the tube (14); and in that the ratio between the distance between the fins (p) and the thickness of each fin (t) is less than or equal to 11.
