A spiral tubular heat exchanger has a housing with branch pipes for the first heat-exchange medium flow with placed it in parallel to each other heat exchange elements, those are arranged as single-spiral spiral pipes with closely adjoining each other turns and with guides for the first heat-exchange medium flow; at that, the ends of each pipe are connected to the inlet and the outlet collectors of the second heat-exchange medium. The heat-exchange elements are arranged as multi-spiral, those adjoin each other with parallel surfaces, and the guides of the first heat-exchange medium are formed by the turns of the heat-exchange elements of the second heat-exchange medium, those form the channels for flow, through those, to the outlet branch pipe, of the first heat-exchange medium; at that the housing is formed by the outer ribs of the heat-exchange elements and by additionally installed end covers with channels for heat-exchange media flow. |
