Turbo-ELF tube is a revolutionary
heat Transfer tube for boiling
on outer surface. It has very excellent heat
transfer coefficient derived from an unique fine
structure based on the boiling phenomenon essentially, It
is different from the conventional integral fin tube which
simply increase the surface area.
1.By forming fine
openings in the surface skin and circumferential tunnels which
connect them under the surface skin, bubbles are generated
continuously so that an extremely high boiling heat transfer
performance can be achieved
2. To prevent the
phenomenon in which sub-cooled refrigerant invades the tunnels ,
fine progections are formed just beneath the openings in the
surface skin to lessen The influence of the sub-cooled refrigerant.
This has improved the heat
transfer performance in all regions including the low heat
added inside the tube to improve the internal heat transfer
coefficient is more improved than that of the : Low Fin Tube .
