核动力发电设备中的蒸汽发生器和过热器,以及石油化工生产工艺过程中的废热锅炉均属高热负荷的换热设备,其中应用的换热元件的型式很多,而带有椭圆端头的插入管式换热元件是目前广泛应用的一种。本文详细地介绍了有椭圆端头的插入管式换热元件放热过程的试验结果。(原文见清华大学技术报告) Steam generators and superheaters in nuclear power plants, as well as waste heat boilers in the petrochemical production process, are heat transfer devices with high thermal loads. There are many types of heat exchange elements to be used, while the insertion of an elliptical tip Tube heat exchanger is a widely used one. This paper describes in detail the experimental results of the exothermic process of an inserted tube heat exchanger with an elliptical tip. (Original text see Tsinghua University Technical Report)
