Abstract

The disclosure relates to a spiral plate heat exchanger (1) for exchanging heat between media, the heat exchanger (1) comprises a spiral body (2) comprising at least one spiral sheet (10a,10b) wound to form 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; a substantially cylindrical shell (4) encircling the spiral body (2); first and second elongated headers (5a, 5b) connected to an outer surface of the cylindrical shell (4), wherein the first elongated header (5a) is fluidly connected to the first flow channel (14a) and the second elongated header (5b) is fluidly connected to the second flow channel (14b); and first connecting elements (8a, 9a) communicating with the first flow channel (14a) through the first elongated header (5a) and second connecting elements (8b, 9b) communicating with the second flow channel (14b) through the second header (5b). The spiral plate heat exchanger (1) further comprises at least one volume reducing element (17) arranged in at least one of the first and second elongated headers (5a, 5b). The disclosure also relates to an elongated header (5a, 5b) for such a spiral plate heat exchanger (1).
