采用单管传热风洞对矩形翅片滴形管和圆管圆翅片进行了传热性能的试验。结果表明,前者的传热性能和气流阻力均优于后者,并用测定的试验数据,提出了相应准则公式。
The heat transfer performance of rectangular fin drop tube and circular tube fin was tested by single tube heat transfer wind tunnel. The results show that the heat transfer performance and airflow resistance of the former are better than the latter, and the corresponding criterion formula is proposed with the measured test data.
