双管双管板热媒热交换器(安全热交换器)

Introduction to Heat Medium Heat Exchanger Constructed with Double Tube and Double Tubesheet(Safe Heat Exchanger)

双管双管板热媒热交换器是近代在双管板基础上发展起来的一种新型管壳式热交换器,也称安全热交换器,适用于管、壳程介质严禁掺混的场合。结合双管板热交换器,对双管双管板热媒热交换器的有关要点做了简要介绍,可为此类热交换器的设计、制造及使用者提供一定的参考。

Heat medium heat exchanger constructed with double tube and double tube-sheet is a new type of tubular heat exchanger developed on the basis of double tube-sheet type in recently times, it is also called safe heat exchanger. This kind of heat exchanger is able to be applied to such occasions where the fluid is strictly prohibited to blend and mix between tube side and shell side. Based on double tube-sheet heat exchanger, some key points of designing and manufacturing for heat medium heat exchanger are introduced, so it can be a reference for designer, manufactur- er and uses for this kind of heat exchanger.
