A fitting, simple and versatile window program (HSHPTM) design using lumped parameters and one-dimensional thermal resistance models

A heat sink-heat pipes thermal module (HSHPTM) applies U-type or L-type heat pipes to transferring the total heat capacity from the heat source to the based plate and fins successfully, and then dissipates heat flow into the surrounding air. This article utilizes Visual Basic commercial software to develop a window program named HSHPTM V1.0 for proper design of the heat sink-heat pipes thermal module. The computing core of the HSHPTM program employs the theoretical thermal resistance analytical approach with iterative convergence stated in this study to obtain a numerical solution. The results show that this calculated error comparison with experimental results is within ±5 %. The embedded U-type heat pipes carry 46 and 63 percentages of the total dissipated heat capacity for one-pair and two-pairs embedded U-type heat sink-heat pipes thermal modules, and dissipate 87.2 % heat flow for six embedded L-type heat pipes, respectively. There has a benefit for HSHPTM V1.0 of rapidly and capably calculating the thermal performance of a heat sink-heat pipes thermal module installed with a processor horizontally by inputting simple and lumped parameters.
