The experiment primarily investigated the effects of nine different ratios of the evaporation and condensation section length on the thermal performance of flat micro grooved heat pipes with the same sec-tion size,the same filling working medium,rectangular and triangular micro grooved wicks,which installed at 90° by continuous increasing input heat flux and forced air cooling.The findings demonstrate that the length ratio of the evaporation and condensation section has a significant effect on the thermal performance of the flat microgroove heat pipe.The ratio of the evaporation and condensation section length was initially selected within the range of 0.8～1.25 for two micro grooved wicks which having good heat transfer per-formance.Compared the flat heat pipe with different micro grooved wicks,it is discovered that under the same circumstances,rectangular microgroove flat heat pipe performed better in terms of transfer perform-ance than triangular microgroove flat heat pipe.It is advised that the range of the length ratio of the evapo-ration and condensation section in the application design is 0.8～1.0,with 1 being the optimal value.The re-search results could provide an accurate reference for the system design of flat micro-channel heat pipe in the fields of solar energy,waste heat recovery,battery thermal management and electronic heat dissipation.
