Spiral plate heat exchanger is widely used in heating, heating and heat dissipation in daily life, condenser of steam turbine and oil cooler of space rocket. It is also widely used in chemical, petroleum, electric power and atomic energy industry. Its main function is to ensure the specific temperature required by the process, and it is also one of the main equipment to improve the energy utilization rate.

Heat exchanger is an independent device, such as heater, cooler and condenser. It is also an integral part of process equipment, such as heat exchanger in ammonia synthesis tower.

Due to the limitation of manufacturing technology and scientific level, the early heat exchanger can only adopt simple structure, with small heat transfer area, large volume and large volume, such as coil type heat exchanger. With the development of manufacturing technology, the tube type heat exchanger is gradually formed, which not only has a large heat transfer area per unit volume, but also has good heat transfer effect, and has long become a typical heat exchanger in industrial production.
