SiO2纳米流体强化换热场与高倍聚光电池冷却协同分析
Collaborative Analysis of Heat Transfer Enhancement of SiO2 Nanofluids and High Concentration Cell Cooling
摘要
Abstract
ABSTRACT:SiO2 nanofluids with different mass fractions were prepared via two step method in order to investigate their thermophysical characteristics and the convective heat transfer mechanism. The particle size and the Zeta potential of SiO2 nanofluids were also measured to characterize the suspension stability of the fluid. And the coefficients of thermal conductivity of nanofluids were studied with different temperature and particle sizes. The results indicate that after 3h with the ultrasonic vibration the suspension stability of the nanofluids satisfy with experiment requirement, and the thermal conductivity of the nanofluids with 5% mass fraction increased 6.8% which compared with the base fluid when the room temperature is 20℃. Meanwhile, the efficiency with the different nanofluids cooling Fresnel high concentrated performance on the gallium arsenide batteries is evaluated with the field synergy angle,which included by the velocity field and the temperature field. The results show that the field synergy angle is reduced along with the decreases of the nano particle size and increases of the mass fraction of the fluid, and their heat transfer strengthening effect is enhanced.关键词
