提出了提高板翅式换热器性能的一些思路和方法——侧分段、翅片宽度扩展和翅片部分切割。还讨论了已使用多年的前置舞台的效果。介绍了一系列测试，以确定热交换器性能，观察结霜情况，并阐明了这些方法的效果。关键词:平板换热器，翅片管换热器，换热器，霜冻，性能，翅片。单位:SICitation:Symposium，ASHRAE Transactions 1993，第99卷，pt。1.

Proposes some ideas and methods for performance improvement of plate fin-and-tube heat exchangers - side staging, fin width extension and partial cutting of fins. Also discusses the effect of front staging, which has been used for years. Describes a series tests to determine heat exchanger performance to observe frost formation, and clarifies the effects of these methods.KEYWORDS: Flat plate heat exchangers, finned tube heat exchangers, heat exchangers, frost, performance, fins.Units: SI
