Experimental Analysis on Inclined Heat Pipe With Alternative Fluids

In most cases, heat pipes are utilized to transport heat effectively between two solid contacts. In order to accommodate the current trends of power and flux level of upcoming micro devices, an efficient thermal management system is required. Currently, experimental studies are being conducted to determine the thermal performance of a Thermosyphon heat pipe. First, it was explored how operational conditions affected the thermal efficiency of the Thermosyphon heat pipe. A thermosyphon heat pipe measuring 16mm in diameter and 570mm in length will be used for the experimental investigation, and de-ionized water will be used as the working fluid at a flow rate of 10 milliliters per second, 15 milliliters per second, and 20 milliliters per second for different heat inputs of 100, 150, 200, 250, and 300 milliliters per second. Using water as the working fluid, an ideal flow rate and an ideal heat input for the system have been measured. The tilt angle of the heat pipe is taken to be 45 ⁰ . Second, the impact of working fluids on thermosyphon heat pipe performance was investigated. Ammonia, DI water, and methanol were three of the working fluids that were used. The results of the study were compared with those obtained with the use of ammonia or methanol as working fluids, in order to show that the results obtained with de-ionized water were more reliable. Ammonia has less resistance than the other two working fluids, according to a comparison of the resistance, efficiency, and heat transfer coefficient of heat pipes for the three fluids.
