Unlike conventional heat exchangers, HPHX employs heat pipes for more efficient heat transfer. However, augmenting heat exchange efficiency by adding thin fins to the heat pipe’s exterior necessitates intricate grid-based interpretation, resulting in diminished accuracy dur to the high computational costs involved. Here, we employed a porous media modeling approach to the external fin area of the heat pipe to conduct a thorough computational analysis of HPHX. Variations in heat transfer rate and effectiveness in the heat exchanger were extensively investigated based on different porous media modeling methods. These findings offer a methodological advancement in computational analysis for HPHX heat exchangers, enhancing the precision of predicting thermal and fluid performance.
