The sleeve finned tube is an efficient heat exchange element with ribbed wall surfaces, and the heat exchange of the heat exchanger is achieved through the heat transfer of the finned tube. Choosing finned tubes with good heat transfer performance and compact structure is the key to the design and manufacturing of heat exchangers.
The sleeve finned tube heat exchanger belongs to a type of compact heat exchanger, which expands the heat transfer area and promotes turbulence through the heat exchange surface with ribs on the outside of the cooling tube. The shape of the rib surface is square. By increasing the contact area on both sides, heat transfer is enhanced and has the advantages of saving on-site space and metal materials. Sleeve is a new type of energy-saving heat exchange element. It has a compact structure, small size, light weight, low water consumption, good stiffness, long service life, large heat dissipation capacity, small gas side resistance, good vibration resistance, and convenient maintenance and cleaning.
The sleeve type heat exchanger is suitable for small flow liquid liquid exchange and general vapor liquid, condensation and other occasions, with strong practicality. It is widely used in industries such as petrochemicals, electricity, ships, locomotives, refrigeration, etc., especially in petrochemical inter stage coolers, power air coolers, and hydrogen coolers. With the development of industry, the problems of water shortage and environmental pollution in industry are becoming increasingly prominent. The application of high-efficiency, energy-saving, and consumption reducing sleeve heat exchangers has attracted more attention from people.
