Study on Heat Transfer Design of Green Energy-saving Heating Pipe

Abstract

To design a green energy-saving heating pipe, this paper studied the structural transformation of the heating pipe and carried out the effect simulation analysis. The key is to add an impeller device inside the ordinary heating pipe to convert part of the kinetic energy of the fluid in the heating pipe into the mechanical energy of the impeller. The energy generated by the rotation of the impeller can be transferred through gears, connecting rods, and other components and converted into heat energy for recovery in the boiler room to achieve the reheating effect. This design model is mainly used by Solid works and then imported into ANSYSF Fluent for numerical simulation to analyze and study the fluid around the impeller. The result showed that the flow velocity of the fluid around the impeller was reduced, and the local resistance loss was negligible. Meanwhile, part of the kinetic energy of the fluid has been converted into the mechanical energy of the impeller, effectively realizing energy saving.
