1. Based on thick-walled welded pipes and seamless tubes, with specific tools, use three-roll cross rolling processing;

2. The teeth can be processed or not processed in the tube, and twist iron can also be inserted for reinforcement;

3. The tooth shape is a staggered diamond or rectangular grid unit, and the bottoms of the tooth grooves are mutually Connected, tooth top upsetting;

4. Processing range: pipe diameter 12.7mm-31.8mm, wall thickness 0.8mm-3mm;

5. Can process common titanium, austenite, ferrite and other stainless steel materials;

 

 

The fish scales like profiles are distributed uniformly on the enhanced surface of the tube while the circular channels are formed helically under the profiles. The special porous structure has provided lots of nucleation points which are critical in flooded boiling. It has reduced the thickness of the liquid film between the bubbles and the tube wall to decrease the thermal resistance. Meanwhile, it can accelerate the circulation of liquid and bubbles in the fin root channels and cavity pockets due to the thermos-siphon effect, which improves both internal and external convection.

 

This circulation can also help to remove impurities to reduce fouling. In this special configuration, refrigerant can boil more bubbles continuously at less superheat. The shell side heat transfer coefficient can be as high as 30 times that of a plain tube.

Furthermore, the tube side heat transfer coefficient is again improved contributing to increased surface area and turbulent flow induced by helical ridges inside the tube.

 

 

1. Increase the effective heat transfer area outside the tube;

2. Increase the number of vaporization cores on the outer surface;

3. Ω-shaped tooth groove structure accelerates gas detachment and avoids film boiling;

4. Connected cogging structure, the medium can be moved anywhere in the cogging circulate to avoid local evaporation;

5. Porous structure enhances the wettability of the medium to the tube wall;

6. Can be used as a falling film evaporation tube at the same time;

 

 

 

 

High performance evaporator fin tubes can also be found applied in any field where nucleate boiling needs to be driven by very small temperature difference in heat transfer such as the separation of light hydrocarbons, geothermal engineering, ocean thermal power generation, waste heat recovery and in evaporation of the aqueous solution at low temperature etc.
