Abstract

The conduit consists of a tube (1) with heated liquid. On the outer face (5) are fins (4). The two are placed in a square tube (3). The transverse dimensions (DC3 & DD3) of the internal faces (DC3) are less than those (D4) of the fins. The fins are bent (9) to fit. The internal cross-section diagonal (DD3) dimension is greater than that of the fins before bending. This gives a passage (13) for fluid circulation between the internal wall (11) of the tube (3) and the outer wall (5) of the inner tube. The fins are virtually circular before bending.
