Decline in heat transfer performance of heat exchangers for liquid air separation units

Decline in heat transfer performance of heat exchangers for liquid air separation units
In addition, the heat transfer temperature difference between the hot and cold fluid also has an impact on the temperature distribution of the heat exchanger, the greater the temperature difference, intensifying the difference in heat transfer between the different flow channels of fluid, is the heat exchanger channel between the axial and circumferential guide heat increases, resulting in an increase in the temperature distribution parameters of each section.
