Design and performance analysis of a discontinuous spiral baffle heat exchanger
In this paper,a new type of discontinuous spiral baffle heat exchanger is designed,and its heat transfer performance is analyzed by numerical simulation.Considering that the wall of heat exchanger is subjected to high temperature at the same time,a preliminary study on the wall cooling is also carried out.The results show that there is no"Flow dead zone"of relatively stagnant flow,and the air temperature drops to about 38%of the original airflow temperature.The heat transfer Coefficient of the Heat Exchanger is k = 344.4 W/(M2·K),and the heat transfer performance is better.
