Low driving force self-cleaning and heat transfer enhancement rotor in heat exchange tube

The invention provides a low driving force self-cleaning and heat transfer enhancement rotor in a heat exchange tube, which is particularly suitable for the heat transfer enhancement of a viscous fluid of the tube side. The rotor comprises a hollow cylinder and blades, wherein each blade is of a spiral structure; the root part of the outer surface of the blade is tangential with the edge of the hollow cylinder; and when a fluid axially enters from the heat exchange pipe, the acting force of the fluid vertical to the radial direction of the blade enables the rotor to rotate around a rotary shaft. According to the invention, as the root part of the blade is tangential with the edge of the hollow cylinder, the acting area of the fluid on the blade is increased. The larger the radius of the hollow cylinder is, the more obvious the effect becomes. Consequently, if the rotation driving force applied to the rotor is increased, the rotor is more favorable for the heat transfer enhancement in the case of relatively large viscosity of a medium in the heat exchange pipe or low kinetic energy of the fluid. As the outer surface of the root part of the rotor is tangential with the edge of the hollow cylinder to form a smooth curve, the outer surface of the blade does not scale easily, thereby prolonging the using period of the entire device and reducing the cleaning frequency.
