Designed a new type of tube heat exchanger which insert spoiler components

and then at different velocity the pipe inner wall surface average heat transfer coefficient

heat transfer capacity

the average Nu and friction resistance variation characteristics of the new heat exchanger tube and corrugated tube

smooth tube are analyzed and compared.The results showed that the enhanced heat transfer capacity and the pressure loss of insert spoiler element heat transfer tube will be great

so its economy must be considered when choosing of heat exchange tube inserted by disturbance device in practical application.Under the same pump power consumption conditions

thermal efficiency for metal-wire inserts in heat exchanger tube and corrugated tube are very close.But for metal-wire inserts in heat exchanger tube the manufacturing process is convenient

flexible and more suitable for the existing heat exchanger transformation.Therefore

the heat exchange tube also has extensive application value.
