Thermosyphons are hollow sealed weak less heat pipes and its crucial role towards cooling of highly heat dissipating electronics and industrial thermal application. The effect of binarymixture as a working fluid on performance of inclined two phase closed thermosyphonwill investigate in this paper. The thermosyphon has three principle components, condenser is at top, adiabatic at middle section and an evaporator at bottom section. Investigation has been done to assess the effects of binary mixture fluidproportion on inclined thermoyphon. The thermosyphonselected has 25.4 mm (1 inch) diameter and length of 500 mm (have 200 mm condenser, 100 mm an adiabatic and 200 mm evaporator section) designed to the 240 watt heat dissipation from the application. The ethanol methanol mixture proportion (like 50-50%, 60-40% and 70-30 % by volume) is working fluid with filling 60% of evaporator section. The investigation is done by applying the heat load to the thermosyphonusing four band heater of each 60 watt capacity and water as coolant flowing through condenser jacket to cool condenser by pump and flow control arrangement. The investigation of inclinedthermosyphon has done at inclination of 90°, 75°, 60°, 45°, 30° and 15° with reference to horizontal axis to study the effect on heat transfer performance of the system. The Properties of Ethanol Methanol Mixtures studied at various proportions and find out maximum heat input for various mixtures by heat transfer limitations correlations. So, heat input of 240 W is supply to 60% filling of evaporator region. It found the outcome from the experimental trial is that ethanol methanol (60-40) % mixture proportion of binary fluid gives better performance of thermosyphon at angle inclination of 45° at 0.001667 kg/s of cooling water flow rate than other. Efficiency of pipe for (60:40) mixture is 23.26 % while (70:30) shows less 20.35 % and (50:50) gives lower 17.44 % at 45° inclination and 0.001667 kg/s mass flow rate. Also it come to know that (50:50) and (70:30) mixture proportions gives better performance at 60° and 90° that of other angle inclinations.
