Title of the articleModern heat exchanger heat transfer elements equipment and manufacturing technology
Abstract.This paper analyzes the design and manufacture of heat transfer components used in tube bundles of heat transfer equipment, including smooth pipes and pipes with artificial roughness of the walls, as well as the design of twisted tubes like «confusor-diffuser» and spring-twisted channels, previously protected by patents of the Russian Federation. Special attention is given to the development of methods and technology of twisted pipes and channels using laser welding and rotary forging process. The paper also shows the basic vector and parametric equations that describe the configuration of the flow tube «confusor-diffuser» and spring-twisted channels used in the hardware – software system to manage the process of manufacturing of pipes. Described conventional technology for smooth pipes, as well as an alternative method of production. Gives examples of twisted pipes made of stainless steel and carbon steel by rotary forging, and spring-twisted channels made using the technology of laser welding.
Keywords.Twisted tube type «confuser-diffuser», spring-coiled channels, laser welding, rotary forging.
