Project Description

Serrated finned tube

Serrated finned tube manufactuer

Serrated finned tube. Mainly suitable for gas-based heating furnaces and various types of heat exchange equipment in petroleum, chemical, metallurgical, electric power, textile, and other industries. At present, the general spiral finned tube has the following deficiencies: 1. The light fins cannot make the airflow passing through the fins generate turbulence, and the heat transfer efficiency is low; 2. The light fins high-tooth winding fin roots have wrinkles and are easy to accumulate Dust and dust accumulation are not easy to remove; 3. It is not conducive to the selection of small diameter and high fin-shaped fin tubes; 4. The temperature stress in use is large.
Advantages of serrated finned tube
1. The serrated fin can make the airflow passing through the fin generate turbulence, which can obviously improve the heat transfer efficiency, which can increase the thermal efficiency by 10-20% compared with the optical fin.
2. The roots of the zigzag high-tooth winding fins have no wrinkles, which can reduce dust accumulation and make it easier to remove dust.
3. It is conducive to the selection of finned tubes with small diameters and high fin shapes.
4. It can reduce the temperature stress in use.
