It is proposed to use highly effective heat exchange surfaces from the tubes of the spiral corrugated profile for heat regenerators GTU, which will ensure a reduction of mass-dimensions by 30-40% in comparison with heat exchangers made of smooth round tubes and an increase in the KPD GTU from 18-25% to 38-41%. Also, by replacing the round brass tubes with spiral corrugated brass tubes with a diameter of 16 1 mm, lengths of 2 and 4 m, the heat exchangers can be upgraded, which are used in heating and hot water supply systems for buildings of various purposes. At the same time, the heat transfer coefficient increases by 30-50%. For the manufacture of such tubes, technology and equipment for their metal forming based on the roller spinning process have been developed. Numerical modeling and experimental studies have established the necessary parameters of profiled tubes. The model of the effective heat exchanger is made.
