Helical groove tubes, also known as helical grooved tubes, are an excellent bilaterally reinforced heat exchange tubes, which significantly enhance the heat exchange process of the single-phase fluid inside the tube. As the fluid flows through the tube, it is subjected to the influence of the helical grooves.

Guidance: Part of the fluid along the wall rotates along a groove; when another part of the fluid flows along the wall axially, the helical ridges also cause periodic disturbances in the fluid. The former effect is beneficial for thinning the fluid.

Boundary layer; the latter action causes disturbances in the fluid mass within the boundary layer, thereby accelerating the heat transfer from the wall to the bulk fluid. The combined effect of both actions enhances the heat exchange efficiency within the tube.

Comprehensive introduction to its working principle, features, structural parameters, performance evaluation criteria, production methods, and applications, etc.

Working Principle

Helical groove tube, which is a type of heat exchange tube formed by rolling or other processing methods to create helical grooves on its inner and outer surfaces. As fluid flows within the tube, it is guided by the helical groove patterns, leading to

A portion of the fluid along the wall rotates partially; when another portion of the fluid flows along the wall axially, the helical protrusions also cause periodic disturbances in the fluid. The former action is beneficial for thinning the fluid boundary layer; the latter

A mechanism that induces disturbances in the fluid mass within the boundary layer, thereby accelerating heat transfer from the wall to the fluid bulk. The combined effect of these two mechanisms enhances the heat exchange efficiency within the pipe. The strong...

Heat transfer is primarily manifested in the condensation process. When there is a phase change of condensation in the shell side, the helical grooves serve as channels for draining condensate, which can thin the condensate film on both sides of the grooves, thereby reducing thermal resistance and improving the heat transfer efficiency of the condensation system.

Features of Spiral Groove Tube

(1) Heat transfer can be simultaneously enhanced both inside and outside the pipe.

(2) Low processing costs

(3) Broad applicability. Enhances evaporation, condensation, and heat transfer in both gas and liquid phases for media inside and outside pipes.
