ABSTRACT:
The invention relates to a heat exchanger (1) with plate structure, comprising a stack (6) of plates composed of circular heat transfer plates (10) by welding and fitted inside a housing unit (2) used as a pressure vessel, whose periphery is provided with flow guides (21, 22), by means of which the second heat transfer medium is guided to desired ducts in the stack (6) of plates. By means of spacing plates (32) fixed inside the flow guides (21, 22), it is possible to arranged several draughts for the stream of the heat transfer medium.
