Abstract
We compared four kinds of heat exchangers made of porous material. Moreover, we proposed a new model which predicts the performance of the porous metal fins. Heat transfer coefficient of porous metal fins can be predicted within an error of 10% by our model. The predictive model has two assumptions. One is that the perimeter in the porous metal fin per cross-sectional area of that is independent of the heights of fins and number of porous cells. Another assumption is that heat transfer coefficient of porous metal fin is also independent of the heights of fins and number of porous cells.
