FIELD: heating.

SUBSTANCE: in heat exchanger comprising at least one inner heat exchanging pipe with turbulence promoter, turbulence promoter is arranged near inlet hole of heat exchange pipe and represents a cylindrical vessel with holes for inlet and outlet of fluids, inside of which along with the fluid motion there are serially arranged jet-forming nozzle and resonator plate fixed as overhanging in cylindrical vessel with two ledges, which are bowingly bent in opposite directions so that they tightly adjoin inner surface of cylindrical vessel, forming fixation of plate. Heat exchanger may comprises chamber of fluids introduction, which may be equipped with mixing and/or distributing devices. Cylindrical vessel of turbulence promoter may be represented by the section of heat exchange pipe, and additional holes may be arranged in wall of cylindrical vessel of turbulence promoter between inlet hole and jet-forming nozzle.

EFFECT: increased efficiency of heat exchanger.
