Abstract


Results of researches on creation of heatexchange devices, on the basis of experience of creation of the equipment for twisting and change of the direction of the movement of streams of liquids and gases, their turbulences providing destruction of an interface on heat-transmitting surfaces and an intensification of heatexchange processes are presented. As working bodies of the heatexchange device it is offered to use screw rotors in which each cross section through passage differs from previous not only a form, but also an arrangement relatively each other, thus the area of cross section changes, stationarity of the movement of environments is broken, intensity of heatexchange processes increases, technological capabilities extend. Screw rotors are sup-plied with blousings which are created on external surfaces of rotors in the course of their assembly and provide an intensification of heatexchange processes. In work dependences for calculation of key parameters of screw ro-tors are presented.
