Stainless Steel Pool Boiling Evaporator Tube

A fish-scale profile is evenly distributed over the reinforced surface of the tube, while circular channels are formed in a spiral beneath the profile. The special porous structure provides many nucleation sites that are crucial in submerged boiling. It reduces the thickness of the liquid film between the bubble and the tube wall, thereby reducing the thermal resistance. At the same time, due to the thermosiphon effect, the circulation of liquid and bubbles in the fin root channels and cavity pockets can be accelerated, thereby improving internal and external convection.

This circulation can also help remove impurities to reduce scaling. In this particular configuration, the refrigerant can continuously boil more bubbles at a lower superheat. The shell-side heat transfer coefficient can be as high as 30 times that of light tubes.

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.
