  • High temperature heat transfer oil fin tube heating device for large 4cr9si2 has the advantage of high heat transfer efficiency. The high-temperature heat-conducting oil finned tube heating device adopts high-efficiency outer finned tubes. The outer finned tube coils are immersed in a water bath. Compared with ordinary light tubes, the contact area between the evaporation coils and the medium is increased. The total heat transfer coefficient of the coil is determined by the heat transfer coefficient outside the tube. This increases the heat flux per unit tube length and improves the overall heat transfer efficiency.
