FIELD: mechanics.
SUBSTANCE: invention relates to "pipe-in-pipe"-type heat exchangers and can be used in various industrial branches. The proposed heat exchanger comprises an inner pipe with external cylindrical ribs representing hollow pipes and turbulator mounted thereon and representing a helical tape coiled on the rod, a tangential branch pipe to feed intertubular medium and that to discharge aforesaid medium. Note here that straight cylindrical ribs, arranged all long the heat exchanger length, are fitted on the inner pipe outer surface with the help of bent metal plates and brought out into common branch pipes of feeding and discharging inner pipe medium via tube plates.
EFFECT: simplified mounting/dismantling, intensified heat exchange, reduced costs of clearing pipes.
