Which Mainly Includes

Higher heat transfer coefficient. The serrate can make the gas flow across the fins freely, enhancing the turbulent motion and improving the heat transfer effect. Researches show that serrated fin tube's heat transfer eficiency is about 15-20% higher than common solid fin tube.
Reduce metal consume. Due to the higher heat transfer coeficient, for the same amount of heat, serrated fin tubeis with less heat transfer areas, which help reduce the metal consume.
Anti-ash-deposition and anti-scaling. Due to the serrate, it is very hard for the serrated fin tube to deposit the ashand scaling.
It is more flexible to adapt to the changes of gas flow direction.
The important features of this configuration are efficient, effective bond of fin to tube under all conditions oftemperature and pressure, and ability to withstand high fin side temperatures, This serrated fin configuration is even better to withstand the fin fouling if that is a problem in the application. This gives better heat transfer propertiescompared to solid fins.
