Thermal characterisation analysis of heat-sink heat pipes under forced convection

Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.

The thermal performance of embedded heat pipes heat sink cooling system presents a viable active method for reducing peak operating temperatures of the heat source. This type of embedded heat pipes heat sink module successively transfer heat from a heat source to the heat pipes, the heat sink and their surroundings, and are suitable for cooling electronic systems via forced convection mechanism. The main purpose of this study is to establish a theoretical model that is based on the performance of embedded heat pipes heat sink under different wind speeds and heater areas, and calculate the heat flow of individual embedded heat pipe employed the least smoothing square method and the thermal performance experiment. The computer core of heat sink heat pipes thermal module (HSHPTM) program applies the theoretical thermal resistance analytical approach with iterative convergence stated in the present study to obtain numerical solution. The results show that this calculating error comparison with experimental results is within ±5%. This HSHPTM has the advantage of rapidly calculating the thermal performance of a heat sink-heat pipes thermal module installed with processor horizontally by inputting simple parameters. The result of this work is a useful thermal management method to facilitate rapid analysis.
