In this paper, systematic experimental investigations were carried out for a wickless heat pipe with flat evaporator having dimensions (100 x 100x 30) mm. Flat-square electrical element was used to simulate the heat source of electronic part with dimensions of (100 x 100) mm. The aim of this paper presents the effect of fill ratio and cooling water mass flow rate on thermal performance of a wickless heat pipe. Experiments were performed to evaluate performance of wickless heat pipe for range of input power from 10 W to 100 W. The fill ratios used in the present work were 15 %, 25 %50 % and 85 %. The cooling water mass flow rate was also changed from 0.0083 kg/s to 0.033 kg / s. Experimental results showed that the maximum value of wall evaporator temperature was 115°C at input power of 100 W and a fill ratio of 15 %. Results also showed that the maximum value of the total resistance was 0.8°C/W.
