Abstract

Heat-exchanging means comprises pipe means (1) provided with first pipe means (2) suitable for receiving a first fluid and located inside second pipe means (3) suitable for receiving a second fluid, between said first pipe means (2) and said second pipe means (3) interspace means (4) being defined; strip means (5) is further provided that is positioned in said interspace means (4). The pipe means (1) is provided with projecting means (7) comprising protrusion means (7) having a shape that is substantially elongated along a direction (Z) wherein said pipe means (1) extends.
The projecting means (7) comprises first projecting means (7a) and second projecting means (7b) that are staggered in relation to one another.
