Spiral threaded tube heat exchanger is a new type of high-efficiency and energy-saving heat exchange equipment introduced in recent years. It completely breaks through the design concept of traditional tube and shell heat exchangers, and has undergone significant changes compared to traditional tube and shell heat exchangers in terms of material selection, structural form, appearance and volume. Multiple technological innovations have significantly surpassed traditional tube and shell heat exchangers in terms of appearance and performance, It has changed the characteristics of traditional heat exchangers such as simple structure, large volume, rough appearance, and low efficiency, and is an updated product of traditional heat exchangers.
