There are the results of the research on creating a heat exchanger. It is based on the experience of creating equipment for swirling of liquid and gas flows and changing of their directions, their whirling, leading to destruction of the boundary layer on heat-transfer surfaces and intensification of heat-exchange processes. Screw rotors are suggested as working bodies of the heat exchanger. Each flow-cross section in them differs from the previous not only by its form but also by its location relative to each other. With that, the cross-section area changes, the medium motion stationary breaks, the intensity of heatexchange processes increases, technological capabilities enhance. Screw rotors are supplied with laps created on exterior surfaces of rotors during their assembling and allowing intensification of heatexchange processes. Dependencies for calculating of screw rotors basic characteristics are presented in the work. Screw rotors provided with helical grooves on the inner surface with a spiral lines on the outer surface of different pitch and number of visits. The work is done on the basis of research carried out at the Kuban state agrarian University on the use of helical rotors in industry, construction and agriculture [1-23]
