Heat exchanger optimization
Thread Content
After the heat exchanger is designed, how can one evaluate the quality of that design? How to optimize heat exchangers.
I think it is necessary to conduct performance tests on the product to determine whether it can meet the heat exchange requirements calculated theoretically.
In fact, in design mode, heat exchanger design software is solving an optimization problem. There are two objective functions for heat exchanger optimization: heat transfer area and cost. The heat exchange area forms a relatively simple objective function, while the constraints include geometric dimensions (such as shell diameter, tube length, baffle spacing, and upper and lower limits on the number of tube passes), as well as the allowable pressure drop. After automatic design, it needs to be converted into a rating model, with dimensions adjusted according to the standard series of heat exchangers, in order to control tolerances and vibration issues.
