In multiple fields such as industrial production, energy utilization, and peoples livelihood security, the level of heat transfer efficiency directly determines the energy efficiency, cost, and stability of the system. As an efficient heat transfer component optimized and upgraded based on traditional coil pipes, Threaded Coil Pipes, with their unique spiral structure design and enhanced heat transfer mechanism, have broken through the performance limitations of traditional straight pipes and ordinary coil pipes, becoming core components in modern heat exchange systems, widely used in various industries such as chemical engineering, petroleum, electric power, medicine, and food, helping industries save energy, improve efficiency, and upgrade technologies.

I. Core Definition and Structural Characteristics of Threaded Coil Pipes

Essentially, a Threaded Coil Pipe is a spiral heat transfer component made by precision processing of metal pipes (such as stainless steel, copper alloy, titanium alloy, etc.) to form continuous spiral threads on the inner or outer wall of the pipe, followed by bending and forming. It is often combined with components such as shells, tube sheets, and end caps to form a threaded coil heat exchanger, forming a complete heat exchange system. Its core structural highlights lie in the dual design of "thread reinforcement" and "spiral layout", which work together to lay the foundation for its high-efficiency heat transfer.

II. Core Working Principle: Synergistic Mechanism of Turbulence Enhancement and High-Efficiency Heat Transfer

The high-efficiency heat transfer performance of Threaded Coil Pipes originates from the optimization of fluid flow state and the enhancement of heat transfer mechanism. It mainly achieves rapid heat transfer through three major effects, and the heat transfer efficiency is significantly improved compared with traditional smooth pipes and ordinary coil pipes.

• • Secondary circulation (Dean vortices): Increases heat transfer coefficient by 30%–50%, up to 14000 W/(m²·℃).
• • Surface area expansion + turbulence: Inner threads increase area and reduce laminar sublayer, adding another 20%–35%.
• • Countercurrent optimization & self-cleaning: ΔT >150℃, fouling factor reduced by 70%.
