The feature of high flux heat exchange tubes is that powder is composed on the base metal of heat exchange tubes to change the status of boiling surface to form porosity between particles and form nucleate boiling center, so as to change the mem-brane-shaped boiling into nucleate boiling and significantly improve the boiling heat transfer coefficient. 

APPLICATIONS

Heat transfer of liquid-gas phase changing and boiling in the petrochemical, chemical and metallurgy industries, sea water desalination, natural gas storage and transport, air separation and refrigeration.

FEATURES AND BENEFITS

+ Double-side reinforced structure is used, such as outer longitudinal slots with inner porous or outer porous with inner slots
+ High critical heat load. The critical heat load of high flux heat exchange tube is about twice of that of ordinary tube
+ The boiling could be maintained at small temperature difference. With the same heat flow intensity, the effective temperature difference required by high flux heat exchange tubes is only 10% ~ 15% of that of ordinary smooth tubes
+ Excellent anti-blockage capacity and scaling resistance performance
