  • Based on miniature flat heat pipe(MFHP) with the micro-grooved surface,an experimental study was performed to understand the boiling characteristics and critical heat flux(CHF) of carbon nanotube(CNT) suspensions at different pressures and CNTmass concentrations.The experimental results indicate that,the concentration of CNTsuspensions could enhance significantly the boiling heat transfer characteristics of flat heat pipe evaporator,and the heat transfer enhancement of CNTsuspensions and CHFenhancement greatly increases with the decline of the test pressure.The concentration of suspensions has great influence on the boiling coefficient and CHF.At the lower concentration,boiling coefficient and CHFwill grow slowly with the increase of concentration.But,if the concentration exceeds 2%,the influence of concentration will disappear.
