摘要

为了改善分离式热管的工作性能并提高其不同条件下的适用性，动力型热管受到广泛关注。本文通过热管的2条并联下降管支路实现了重力型和动力型热管运行模式的切换，对比了2种驱动方式下热管的传热性能和运行状态。研究表明：当工质流经下降管支路1、支路2（泵关）以及支路2（泵开）时，热管的正常工作负荷范围存在显著差异。液泵的存在给管内工质的流动增加了阻力，泵关闭时，热管的传热极限降低，泵启动后，传热极限增大。在波动运行阶段，储液器无法起到气液分离的作用，当工质流经下降管支路2（泵关）时，相比支路1，热管的波动周期更长、波动幅度更大。在稳定运行阶段，储液器可以带来较好的气液分离效果。

Abstract

Pump-driven two-phase thermosyphon loops (TPTLs) have garnered widespread attention to improve the performance and applicability of TPTLs under various conditions. This study compared the heat-transfer performance and operational states of a TPTL using two parallel downcomer branches to switch between gravity- and pump-driven TPTL operation modes. Significant differences were observed in the normal working load range of the TPTL when the working fluid flowed through downcomer branches 1 and 2 (pump off)

or only through branch 2 (pump on). The presence of a liquid pump increased the resistance to the fluid flow within the loop. When the pump was turned off

the heat-transfer limit of the TPTL decreased

and it increased when the pump was on. During the oscillatory operational stage

the reservoir was unable to effectively separate the vapor and liquid. When the working fluid flowed through downcomer branch 2 (pump off)

the TPTL exhibited a longer fluctuation cycle and greater amplitude compared to those during the flow through branch 1. In the stable operational stage

the reservoir provided better vapor-liquid separation.
