摘要

摘要本文比较了两种类型的换热器的工艺性能，这两种换热器是为在氦气稳定自然循环的情况下从高温氦气冷却回路中去除热量而设计的。第一个考虑的热交换器是带U形管的管壳式热交换器，另一个是螺旋管式热交换器。利用热过程和流体动力学过程计算，确定了两种替代换热器的热性能，以及其工作空间中流动流体的压降。已经对两种考虑类型的热交换器的几个定义的操作条件进行了计算。热交换器的操作条件对应于特定的氦气流速。

Suitability Assessment of Two Types of Heat Exchangers for High Temperature, Naturally Circulating Helium Cooling Loop

Abstract The paper presents a comparison of the process properties of two types of the heat exchangers designed for the heat removal from a high temperature helium cooling loop with steady natural circulation of helium. The first considered heat exchanger is a shell and tube heat exchanger with U-tubes and the other one is a helical coil heat exchanger. Using the thermal and hydrodynamic process calculations, the thermal performance of the two alternative heat exchangers are determined, as well as the pressure drops of flowing fluids in their workspaces. The calculations have been done for several defined operating conditions of two considered types of heat exchangers. The operating conditions of heat exchangers correspond to the certain helium flow rates.
