摘要

为提高两相流动换热通道的换热能力及系统性能

探究其并联换热通道中流量分配不均的特征

开展了以水为工质的两并联通道换热实验

对流量分配不均所带来的参数变化进行研究。实验参数变化主要包括进口温度、热流密度、进口流量

以及外部扰动、集管结构带来的流量分配差异。将实验结果与模型计算结果进行了对比

结果表明:并联换热通道间流量分配不均时

优先沸腾通道中流量较少

未沸腾通道出口温度明显降低; 增加进口温度、增加热流密度、降低进口流量会导致流量分配不均的出现

其产生和消失对应的进口温度、热流密度、进口流量分别变化了24.8 ℃、175.6 W/m、19.8%

并存在滞后现象; 扰动会加速流量分配不均的出现

对应进口温度相差3.2 ℃; 集管结构会影响优先沸腾通道的位置

单相状态下流量较少的通道倾向于优先沸腾。研究结果可为提高并联换热通道流量分配的均匀性提供参考。

Abstract

This study aims to improve heat transfer performance and operating stability in a two phase cooling system while exploring the characteristics of flow maldistribution in parallel channels. An experimental setup with two parallel channels using water as the working fluid is established to examine the impact of flow maldistribution on system performance. The main factors considered include inlet water temperature

heating flux density

and mass flow rate

and the obtained experimental data are compared with the theoretical calculation results. The results demonstrate that flow maldistribution in parallel channels leads to uneven flow distribution and significant temperature deviations. Specifically

the channel with the less flow experiences boiling first

while the unboiling channel exhibits a considerable reduction in outlet temperature. Additionally

certain factors contribute to the occurrence of flow maldistribution. Increasing the inlet temperature

increasing the heat flux density and reducing the inlet flow rate could lead to flow maldistribution

meantime

the inlet temperature

heat flux density and inlet flow rate corresponding to the occurrence and disappearance of flow maldistribution changed by 24.8 ℃

175.6 W/m

and 19.8%

respectively

and there are lags among them; the external disturbance might accelerate the appearance of flow maldistribution

the corresponding difference of inlet temperature is about 3.2 ℃ in experiment; the header structure affects the position of the firstly boiling channel

and the channel with less flow rate in the single-phase state tends to preferentially boil. These research findings provide valuable insights for improving flow distribution uniformity in parallel channels.
