空冷冷凝器设计

摘要:冷凝器是各工业部门中重要的换热设备之一。换热器作为热量传递中的过程设备，在化工、冶金、石油、动力、食品、国防等工业领域中应用极为广泛。换热器性能的好坏，直接影响着能源利用和转换的效率。近年来，节能工作开始被全球所重视,而换热器特别是高效换热器又是节能措施中关键的设备。因此,无论是从上述各工业的发展,还是从能源的有效利用,换热器的合理设计、制造、选型和运行都有非常重要的意义。

本设计是关于管翅式空冷器的设计。主要内容是进行了冷凝器的工艺计算，结构设计和强度校核。设计内容首先是传热计算，主要是根据设计条件计算换热面积。其次是结构设计以确定各部件的尺寸。最后还包括是强度计算与校核，主要包括管箱结构与校核和支架的校核。

关于设计管翅式冷凝器的各个环节，在后面设计书中做详细的说明。

Design of Air-cooled Condenser

Abstract:Condense is one of the most important heat exchanging equipments in industrial field. As a heat transfer in the processing equipment, exchanger is widely applied in chemical industry, metallurgy, oil, power, food, defense industry. In recent years, the problem of energy-saving is beginning to be regarded all over the world. And heat

exchanger, particularly efficient heat exchanger，It is the key to energy-saving

equipment. Therefore, whether from the foregoing the development of industry, or from efficient energy use, the reasonable heat exchanger design, manufacturing, selection and running all have very important significance.

The manual is about the Finned tube condenser，which included process

calculation , the structural design and intensity . The first part

of this

manual is the h eat transfer’s calculation. Mainly, it is according to the given design conditions to estimate the heat exchanger area. Next is the structure design to determine the size of the components. Finally also

including the strength calculation and checking, mainly including

the Tube Box’s structure and the support checking.

About the design of the Finned tube condenser, The detailed content is in

the back of the design instructions.

Key words: Condenser ; Heat transfer; Structure; Strength
