Test results show the resistance of spiral plate is 30% of that of segmentalbaffle, and the heat transfer efficiency is improved by 10% at the same pressure.
Aiming at the defects existing in the conventional heat exchangers with segmental baffles, a new type of tube-bundle support, called grid-baffle, was suggested.
