FIELD: heating.
SUBSTANCE: invention refers to heat engineering and can be used in coaxial vortex heat exchangers of various purpose. Heat exchanger includes coaxial tubes with spiral multithread grooves with opposing twist direction, forming crossing spiral crimps, where crimps have trapeze shape, and hemispheric (cupped) craters are made at the crossings of opposing spiral crimps; at least two radially adjoining tubes are positioned so that their spiral crimps together form spiral crossing channels with irregular hexagon cross-section.
EFFECT: increased power of heat exchanger due to enhanced heat exchange rate along with reduction of heat exchanger dimensions and increased heat exchange intensity.
