   1. The unique spiral winding structure increases the turbulence effect, and the heat exchange capacity per unit area is 3-7 times that of the traditional heat exchanger.
   2. High heat transfer coefficient, high heat exchanger heat transfer efficiency, good heat transfer effect, high heat transfer coefficient up to 14000W/mВ·k, energy saving effect is remarkable.
   3. Small size. With only one-tenth of the traditional tube and shell heat exchangers, it takes up less space and reduces infrastructure and installation and maintenance costs.
   4. Using a small clearance design to increase the flow rate, the heat exchanger is not easy to foul, and the use and maintenance costs
   are low.
