Experimental investigation and Numerical Analysis of Horizontally Placed Flat Pulsating Heat Pipe for Electronic Cooling

Abstract

The experimental investigation and numerical analysis of horizontally placed flat pulsating heat pipe is carried out. The flat pulsating heat pipe with a width of 11 mm and thickness of 2mm is used for experimental investigation. Out of the total volume of the tube 72 % of the volume is filled with water as working fluid. The processor of a computer act as heat source. The flat pulsating heat pipe takes heat from the processor of and rejects heat at another end. The externally powered fan is used to increase the rate of heat transfer. During the operation the 8 watts of power is consumed by the processor. The maximum temperature recorded during the operation of processor of computer is 323 K. The temperatures are measured with the help of digital laser thermometer. The numerical model is developed with Ansys design modeler. The volume of fluid approach is used to predict the physics of fluid flow during complex phenomenon of evaporation and condensation.
