Improving the cooling performance of the straight finned heat sink (SHS) for computer processor using an inorganic PCM

Abstract

The current laboratory investigationpresents the heat dissipating capabilityof Calcium Chloride Hexahydrate (CaCl2·6H2O) salt inorganicPCM (IPCM) based heat dissipatingarrangement for the thermal regulationof the digital devices likecomputer processors. During the course of the inquiry, a straight finned heat sink (also known as a SHS) was incorporated into the planned IPCM. The IPCM-based SHS thermal regulationmethod is an example of the indirect heat dissipatingtechnology that can do away with the need for the blower-integratedtraditional thermal managementmethods. In order to simulate the thermal radiationthat would be produced by a computer processor, a flat-plate heating element has beenutilized. For a given weight percent of IPCM, two distinct SHS configurations, namelySHS without IPCM (SHS-Plain) and SHS with IPCM (SHS-IPCM), have been investigated. The experiments were carried out at three different energy densities: 1.2 kW/m2, 1.8 kW/m2, and 2.4 kW/m2. After that, the heat transfer characterof the various configurations of SHS has been examined for a pre-set target temperature of 75 °C at theaforementionedpower intensities. The findings revealed that the incorporation of the IPCM with the SHS outperformed in minimizing the heating time of the SHS, which proves the capacity of the IPCM in reducing the temperature of the thermal load on the computer chips.[copyright information to be updated in production process]
