Thermal transport analysis of six circular microchannel heat sink using nanofluid

Electronics devices growth in the last decade of the twentieth century ushered in a revolution inside the electronics segment. Continuous micro-sizes and operation cause these devices to heat up, resulting in a reduction in their performance or damage to their parts. Because heat can decrease device performance and life span while also wasting energy, offering an incorporated and effective cooling system has become a significant part of the design of device equipment. One of the key challenges of modern generation technology is the cooling of electronic devices. Nanofluids have attracted attention in a broad range of engineering implementations due to their great properties, which may be used to effectively cool devices while also improving energy efficiency. In view of the above defects, this numerical research object to examine the chip surface temperature, heat transfer rate, thermal resistance, Darcy friction factor and reliability of microelectronic chips in minichannel heat sinks is scrutinized by utilizing a TiO2/water nanofluid as a coolant and comparing the nanoliquid outcomes with the outcomes of water. TiO2/Water nanofluids at 1%, 2% and 3% volume concentrations are employed for this scrutinization. Here, a commercial CFD ANSYS (R19.2) FLUENT software package is used to analyze the electronic chip performance. The CFD ANSYS (R19.2) FLUENT software package is used for modeling, meshing and simulation of the current study.

Automated summary

The rapid growth of electronics devices in the late 20th century brought about a revolution in the electronics industry. However, the miniaturization and continuous operation of these devices often lead to overheating and reduced performance. To address this issue, it has become essential to incorporate effective cooling systems in device design. Nanofluids, with their excellent properties, have gained attention for their ability to efficiently cool devices and improve energy efficiency. This numerical study focuses on examining the surface temperature, heat transfer rate, thermal resistance, Darcy friction factor, and reliability of microelectronic chips in minichannel heat sinks, by utilizing TiO2/water nanofluids as coolants and comparing the outcomes with conventional water cooling.
