Abstract (en)
[origin: EP3800420A1] A spiral heat exchanger (1) including a spiral body (2) formed by at least one spiral sheet (10a, 10b) wound to form the spiral body (2) forming at least a spiral-shaped first flow channel (14a) for a first medium and a spiral-shaped second flow channel (14b) for a second medium. Distance members (12) are provided to separate the windings of the spiral body (2). Each distance member (12) defines a first longitudinal direction (L) extending between two adjacent windings (10a, 10b) of said at least one spiral sheet (10a, 10b)- Each distance member (12) also defines a transversal direction (T) extending perpendicular to the longitudinal direction (L). At least some of the distance members (12) are provided with a protective sleeve (20) at least partly covering the external surface of the distance member (12). A method of making a spiral body (2) for such a spiral heat exchanger (1).
