ポーラス構造を有する爆発圧着成型二重管式熱交換器の伝熱性能評価

抄録

We aim to propose a heat transfer promoter using uniporous structure fabricated by explosive welding technique toward its practical use. In this study, we evaluate the heat transfer performance of a double-tube heat exchanger in which the outer-tube channel has the uniporous structure and the inner tube is a circular tube. The heat is exchanged between hot water passing through in the inner tube and cold air flowing in the outer porous tube. The heat transfer quantity and the temperature efficiency per unit volume show higher performance than those of a commercial double tube heat exchanger with similar geometry.
