Stainless steel plate-fin heat exchanger

Thread Content

Stainless steel plate-fin heat exchangers are formed by stacking partitions, fins, seals, and other components layer by layer and then soldering them in a vacuum furnace. The enhanced heat transfer provided by the various types of fins results in a significantly improved heat exchange efficiency. Currently, they have been widely used to replace traditional shell-and-tube heat exchangers in industries such as aerospace, construction machinery, petrochemicals, energy, metallurgy, air conditioning, and refrigeration, and are gradually being adopted in other industries as well. Stainless steel plate-fin heat exchangers boast extremely high heat transfer efficiency, with heat transfer coefficients reaching 10,000 W/(m²·K). They have a particularly compact structure, with a specific surface area of up to 1,000 m²/m³. The heat transfer fins are thin and lightweight, offering good adaptability; they are suitable for heat exchange between various media such as gas-gas, gas-liquid, and liquid-liquid. Their advantages include high heat transfer capacity, small size, light weight, and excellent cost-performance ratio.
