Experimental investigation on the thermal performance of air-cooled multi-port flat heat pipes

•R134a AMFHP with 50% FR achieves the best performance among the three FRs.•The performance order of AMFHPs with 50% FR are ammonia > R134a > acetone.•Analysis is conducted about the liquid pool heat transfer of 3 fluids in AMFHPs.•The effect of air velocity on te¯ is obvious, however, its inf...
