AI Technical Summary
Multi-row, multi-loop finned tube heat exchangers have complex structures, making it difficult to quickly and reasonably describe their structural characteristics. The computational complexity is high, and existing methods are time-consuming and lack accuracy.
A simplified description method is adopted to establish the heat exchanger performance calculation logic based on the number of tubes and the loop ratio. By adjusting the wind speed and working fluid flow direction, the model is simplified and combined with a fast iterative algorithm to achieve the second-level simulation design of finned tube heat exchangers.
It achieves fast and accurate simulation calculations under known and unknown flow conditions, improving the calculation speed by 1-2 orders of magnitude. The model has good prediction accuracy and can predict stably at non-boundary operating points, meeting the requirements for rapid selection and design of various structural parameters.
