At first, heat exchange experiment has been done in the case when the spring fin has been inserted as extended heat exchange surface into the heat exchange channel. Within the experimental ranges studied, the small diameter spring achieves the largest heat exchange performance with the smallest pressure loss penalty. Especially, an optimum spring pitch may exist at the p/d value less than 10. Such a desirable spring fin shows large heat exchange performance than inner fin and louvered fin elements. Secondly, an experimental set-up based on the unsteady method that can quickly evaluate the heat transfer performance has been explained. Thirdly, new idea of dynamic heat exchanger unit based on an impinging jet has been introduced., application/pdf}, title = {熱交換器要素の高性能化に関する実験的研究}, year = {2004}, yomi = {イナオカ, キョウジ and センダ, マモル} }
