AI Technical Summary
Technical Problem
Traditional coil heat exchangers suffer from problems such as low heat exchange efficiency, complex structure, and large pressure drop.
Method used
A novel coil heat exchanger was designed, which adopts a baffle structure and parallel heat exchange tubes to increase the heat exchange area and reduce the pressure drop in the tube side. The combined structure of baffles and fixed steel rods improves the fluid flow effect.
Benefits of technology
It improves heat exchange efficiency, reduces tube-side pressure drop, simplifies the structure, is suitable for cryogenic media such as LNG, and reduces space occupation.
