FIELD: power engineering.
SUBSTANCE: spiral heat exchanger under this invention comprises a spiral body formed by at least a single-spiral sheet rolled to form a spiral body, creating at least the first spiral flow channel for the first medium and the second spiral flow channel for the second medium, in which the spiral body is surrounded with a substantially cylindrical jacket equipped with connection elements communicating with the first flow channel and the second flow channel, in which the jacket comprises at least two parts of the jacket, and in which the spiral body is equipped with at least one rigidly attached flange on its outer peripheral surface, on which at least two parts of the jacket are flexibly fixed.
EFFECT: reduced labour intensiveness of works to manufacture, repair and clean a heat exchanger.
