Thermal Analysis of Closed Loop Pulsating Heat Pipe
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 2
Abstract
Recent advances in electronics design and manufacturing have resulted in significant increases in heat flux density through a miniaturization of components and a simultaneous increase in power requirements associated with improved product functionality. As a result, thermal management is one of the highest priority items in the production of high performance microelectronic devices. Closed loop Pulsating Heat Pipes (CLPHP) are heat exchanging devices with multiphase slug and plug flow due to capillary action. The pulsating heat pipes are miniature equipments that consist of an evaporator, condenser and adiabatic zone used for cooling purpose in electronic devices. In this present study, CLPHP’s experiment is conducted by providing vital information on the parameter dependency of their thermal performance. The influence characterization has been made for variation of working fluid with filling ratios, the orientation. CLPHPs are made up of copper tubes with 2 and 3 mm diameters with a number of 2 tons are considered with water as the working fluid. Different heat inputs 16, 32,48W are considered for analysis. The parameters, operating between evaporator and condenser of CLPHP’s are analyzed and simulation is performed using CFD. The liquid volume fractions, pressure and temperature variations among the three sections of CLPHP with different orientations of geometry have been described. Thermal resistance is compared with respect to CFD and experimental values
