<p>The invention concerns a ring-shaped heat exchanger consisting of three coaxial tubular casings (3, 2, 1). Said heat exchanger is characterised in that it consists of a first single-piece assembly formed with outer (1) and intermediate (2) casings mutually connected at each of their ends by a recessed flange (13) to form an annular chamber (6) with radial fluid inlet and outlet (10) and a second single-piece assembly consisting of an inner casing (3) provided at each of its ends with a plate (8) produced in one piece with said inner casing (3), said plate (8) comprising at least two orifices (11, 12) forming independent nozzles emerging, one into the inner chamber (5), the other into the temperature setting chamber (4) for the product with said single-piece assemblies nested together.</p> |
