Spiral plate heat exchangers are heat exchangers consisting of two parallel metal plates rolled into two spiral channels, where the heat exchange between cold and hot fluids occurs through the spiral plate walls. Spiral plate heat exchangers come in two types: removable and non-removable.
Spiral plate heat exchangers offer the advantages of small size, compact equipment, high heat transfer efficiency, and low metal consumption. They are suitable for liquid-liquid, gas-liquid, and gas-gas convective heat transfer, steam condensation, and liquid evaporation heat transfer in industries such as chemicals, petrochemicals, machinery, power, environmental protection, energy conservation, and heat conversion.
