A heat transfer profile (1) comprises a cylindrical inner periphery (2), inside of which a cylindrical first space (5) is formed, a cylindrical outer periphery (3) which is arranged coaxially outside the cylindrical inner periphery (2) and which has a shape cut at least on one side thereof, and blade-like heat transfer flanges (4) which, only over a uniform part of the outer periphery (3), extend between the inner periphery and the outer periphery and which are in contact with both the inner (4a) and the outer (4b) periphery, whereby inside the cut part (6a, 6b) of the outer periphery (3), a second space (7a, 7b) is formed which is defined at least by a section of the inner periphery (2) and two heat transfer flanges (4) and which is open at least from the cut side (6a, 6b) of the outer periphery to the exterior of the outer periphery (3). |
