Fabrication of Micro Heat Pipes of Different Diameter for Cooling of a Desktop Computer Processor

Abstract

The experimental observations stated here is on the basis of heat transfer performance of parallel micro heat pipes (PMHPs) of different diameters (ID of 2mm & 3mm) taking Acetone as a working fluid that can be used for the cooling of desktop processor. The system incorporates of six single, equivalent distance & parallel copper micro heat pipes, without wick, slotted into two copper blocks at the evaporation section. Adiabatic section is bended at an angle of 90° and the condenser section is provided with ten parallel & equivalent distance copper sheets perpendicular to the PMHPs used as external fins. Heat transfer characteristics of PMHPs are determined by conducting the experiment using different diameters with Acetone as a working fluid. A GI sheet of 9X4 inch is heated up using an electric heater and the heat pipes are set up of that sheet. Temperature of the GI sheet and different parts of the heat pipes are taken at an interval of one minute and therefore analyzed the experimental data to evaluate the performance of the heat pipe. The experimental results are compared and it is found that the heat pipes of ID 2mm with the working fluid Acetone can reduce the temperature of the sheet better than the heat pipes of ID 3mm.
