Experimental Analysis of Heat Pipe with Methanol & Water as a Working Fluid

Thermal performance of the equipment’s can be improved in many ways including two phase thermosyphon which is an efficient heat exchanger and can be used to enhance the heat transfer because of phase changes of working fluid. Thermosyphon have simple structure, low resistance, high efficiency and low fabrication cost. In this work two phase thermosyphon will be fabricated to investigate the effect of operating parameters on the heat transport capability. The system consist of evaporator section, adiabatic section, and condenser section with thermocouples located on the wall of thermosyphon. Electric heater will be fitted on the bottom of the evaporator section. The experiments will conducted with three different thermosyphon with inner diameter of 12 mm, 9.5 mm and 6.7 mm. the variation of heat transport capability of the thermosyphon will studied for the input heat transfer rate ranging from 0 W to 1000 W for various filling ratio (30%, 60%, 90%) and with operating temperature (300C, 500C &700C) . Methanol & Water use as working fluids.
