- Finned heating tubes are widely used in industrial applications. They are mainly used to improve heat exchange efficiency and have the following characteristics and application scenarios:
1. Enhanced heat transfer: Finned heating tubes increase the heat transfer area by adding fins to the tube surface, thereby enhancing the heat transfer effect. When the convective heat transfer coefficients of the two fluids differ greatly, adding fins on the side with a smaller heat transfer coefficient can significantly enhance the heat transfer.
2. Compact structure: Since the fins expand the heat transfer area, the heat transfer area per unit volume is increased. Therefore, the finned tube heat exchanger can use fewer tubes under the same heat load, reducing the volume of the heat exchanger.
3. Reasonable use of materials: Finned tubes can flexibly select materials according to heat transfer and process requirements, such as using inlaid or welded finned tubes made of different materials.
4. Reduce scaling: Due to its special structure, finned tubes are not easy to form a uniform overall scaling layer, thus reducing the scaling problem.
5. Diverse application scenarios: Finned tube heat exchangers are widely used in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering, such as surface air coolers, air heaters, fan coils, etc. used in air conditioning engineering.
6. Industrial waste heat recovery: Finned tubes have significant advantages in industrial waste heat recovery. For example, in industries such as chemical, steel, electricity, food, pharmaceutical, papermaking and textile, finned tubes can effectively recycle waste heat, reduce energy waste and reduce enterprise costs.
7. Special equipment: Finned electric heating tubes are widely used in heating fluids that need to be heated, such as process water, heating of hydrocarbons, heating of chemical materials, etc.
8. Explosion-proof structure: Finned electric heating tubes adopt advanced explosion-proof structure, which makes them widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas and other explosion-proof places.
9. High efficiency and energy saving: Finned tube heat exchangers improve heat transfer efficiency, reduce energy consumption, reduce enterprise operating costs, and reduce greenhouse gas emissions, which meets the requirements of energy conservation, emission reduction and environmental protection.
