摘  要
    热管换热器，由于它具有压力损失小、传热效率高、工作可靠、结构紧凑、没有掺混污染、尺寸变化范围广、维护费少等独特的优点，在化工领域内得到了广泛的应用。尤其在高温、高压和大型化的场合下，热管换热器有广阔的发展前途。在硫酸系统中我们为了加强其传热效率，防止露点腐蚀，我们使用热管这样的结构代替一般的翅片管。随着制造工艺上的进一步机械化和自动化以及各种新技术的采用，热管式换热器在这方面将会用更大的发展。
本课题要研究的是热管式换热器，探讨换热器的传热系数、采用的结构及其形式。其结构设计，包括对热管，翅片管及其它零部件的材料和形式的确定及其对其中一部分的强度计算和校核。
关键词：翅片管  传热系数  热管  传热效率 

Abstract
    Heat pipe exchanger，which has further development especially in the environment of high temperature、high pressure and situation with large device， is widely used in the chemistry field in the following years because of its exclusive advantages such as lower lose of pressure，high heat transfer efficiency，a small quantity of maintenance costs and so on . In order to increase the heat transfer efficient in the vitriol system and avoid dew-point rusting，heat pipe has become generally accepted heat transfer elements instead of fin tube in such system. With the arising of variety of new technologies and application of automation and mechanization in the manufacture process，the developing of heat pipe exchanger will occupy an important position in the future.
    In the present paper，a method of design is given on the typical heat pipe exchanger. Heat transfer factors、materials、structures and types are also discussed in the following chapters. The structural design includes： the design of fin tubes and heat pipes and other parts including the calculation and checking of intension for them.
Keywords： fin tube;heat transfer factors;heat transfer efficiency;heat pipe
