Abstract

Heat exchange device (10) comprising a first tubular pipe (11) having inside it a first cylindrical cavity (12) in which a first fluid flows, and a second tubular pipe (16) in which a second fluid flows which in turn exchanges heat with the first fluid. The second tubular pipe (16) is disposed coaxial inside the first cylindrical cavity (12) of the first tubular pipe (11), creating with the first tubular pipe (11) a first annular interstice (17) for the passage of the first fluid. The device (10) is advantageously associated with a source of heating and the second tubular pipe (16) comprises inside it a second cylindrical through cavity (19), which defines another passage for the first fluid, so as to allow it to flow both outside the second tubular pipe (16), through the first annular interstice (17), and also inside the second tubular pipe (16), through the second cylindrical cavity (19).
