In present work the experimentation is carried out in the heat pipe introduce inside concentric-tube heat exchanger. Methanol, Acetone as working fluids, and water as heat transport fluid. The investigation is done by different mass flow rates and temperatures of the fluids. The effect of gravitational angles for 0° and 90° are experimented. The maximum heat transfer performance is obtained at angle is 0°. In this investigation for acetone as working fluid there is an increment of 30.42% for effectiveness, 2.5% for Reynolds number and 21.57% decrease in thermal resistance than with methanol. This experimentation clearly shows that heat pipe heat exchanger with acetone exhibits enhanced performance when related with methanol.
