An experimentation is carried out to enhance the thermal performance of cylindrical heat pipes induced in a heat exchanger. In this work, working fluids and heat transport fluid considered are methanol, acetone, and water. Investigation is done with horizontal and vertical orientation angles 0º and 90º. Further, analysis are made with the mass flow rate for hot and cold fluid ranges from 40 to 120 LPH and 20 to 60 LPH, the inlet temperatures of hot and cold fluid as 50ºC to 70ºC, and 30.5ºC. The results shows that the maximum performance are observed at 60ºC and 100 LPH, this is the optimum condition for this work. The maximum thermal performance is obtained when the inclination angle is 0º. It is achieved when acetone as working fluid the percentage increase in effectiveness, heat transfer coefficient, heat transfer rate observed as 6.84%, 14.34%, 7.74%, and 93.3% decrement in thermal resistance is observed when compared with the performance of the heat pipe heat exchanger with methanol as a working fluid.
