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.
