摘要

考察了以水为工质，在不同的加热功率和不同的充液率情况下，脉动热管在不同加热方式（垂直底部加热和水平一侧加热）时的热输送特性。固定充液率，对比了脉动热管采用不同工质（微胶囊流体、氧化铝纳米流体、水）在不同加热功率、不同放置加热方式下的热输送特性。结果发现：功能热流体（微胶囊流体、氧化铝纳米流体）作为脉动热管的工质都起到强化热输送能力的作用，均优于水。垂直底部加热时，1%微胶囊流体作为工质的脉动热管的热输送能力较优，水平一侧加热时，0.1%氧化铝纳米流体较优，但微胶囊流体稳定性要比氧化铝纳米流体好。

Abstract

Experimental investigation was conducted to explore the heattransport capability of pulsating heat pipe (PHP) working with different working fluidsThe heat transfer characteristics of PHP with water as working fluid were studied under different liquid filling rates

different heat loads and different inclination angles (0°and 90°).The heattransport capabilities of pulsating heat pipes with different working fluids (FS39E microcapsule fluid

water

Al2O3 nanofluid) were comparedThe results showed that the heattransport capability of PHP could be enhanced by using functional thermal fluids (FS39E microcapsule fluid and Al2O3 nano-fluid) as working fluid under specific conditionWhen using vertical bottom heating mode (inclination angle=90°)

1% FS-39E microcapsule fluid was the better working fluidWhen using horizontal heating mode (inclination angle=0°)

0.1% Al2O3 nanofluid was the better working fluidBut the stability of microcapsule fluid was much better than Al2O3 nanofluid
