针对换流阀元件在工作时需要高效冷却的要求
采用全氟己烷类液体为工质的微通道相变冷却代替传统水冷系统
并对其在圆形、方形、三角形和梯形4种截面形状微通道内的流动沸腾特性进行了数值模拟
质量流量范围为0.000 1~0.002 kg/s
热流密度范围为50~500 kW/m

。数值分析结果表明:通道内的锐角边会限制气泡的生长
加速气泡的融合、破碎;局部换热系数沿流动方向逐渐增大
相同当量直径下三角形通道局部换热系数最大
圆形次之
梯形最小;随着热流密度与质量流量增大
4种通道的平均换热系数均增大
当质量流量增大19倍时
换热系数增大0.11~0.32倍
压降增大5.62~8.98倍;当热流密度增大9倍时
换热系数增大0.16~0.20倍
压降增大1.08~1.53倍;三角形通道的性能因子最大
综合换热性能最佳。该研究可为换流阀微通道相变冷却系统的设计提供理论依据。
