一、引言七十年代以来,随着能源的日益紧张,节省能源愈来愈重要。因此,用于余热回收的热管换热器受到人们的广泛重视。热管换热器是近期发展起来的一种新型换热设备,要想在更多领域内取代传统的换热设备,还有许多工作要做。目前,热管换热器的热力设计仍然按常规的间壁式换热器的设计方法进行计算,本文在此设计方法的基础上提出了一种简便的优化设计方法。

I. Introduction Since the 1970s, as energy has become increasingly tense, energy conservation has become increasingly important. Therefore, the heat pipe heat exchanger for waste heat recovery has drawn people’s attention. Heat pipe heat exchanger is a recent development of a new type of heat exchange equipment, in order to replace the traditional heat exchange equipment in more areas, there is still much work to be done. At present, the thermal design of the heat pipe heat exchanger is still calculated according to the conventional design method of the inter-wall heat exchanger. In this paper, a simple and optimal design method is proposed based on this design method.
