Integral Low Fin Tube Serrated Fins 

The Integral Low Fin Tube serrated fins is a special-shaped finned tube that is processed by the external bare tube and is suitable for use as a heat transfer element of a horizontal shell-and-tube condenser. Compared with the common low-ribbed pipe,the structural characteristics of the pipe are: the fins are dense,the fin pitch can be as small as 0.5mm, and the outer edge of the fin has zigzag notches.The sides of the piece are rough rather than smooth,which is different to the low-ribbed pipe.The Serrated finned tube is a new type of surface discharge heat transfer tube which is manufactured by studying the mechanism of condensation heat transfer. According to the single tube test, R l I and R 1 3 are the condensing medium under the same temperature difference, and the condensation heat coefficient is 10-20 times of the smooth tube and 1.5-2 times that of the low rib tube. The strengthening mechanical principle: 1. Due to the smaller fin pitch, the c…
