“…Three different microchannel arrangements are modelled and simulated using commercial CFD software. The total layer selection is selected based on the study done by Kamaruzaman et al, [1]. All models have microchannels with a height of 100 micrometer, length of 200 micrometer and width of 800 micrometer.…”

“…Nowadays microchannel cooling devices have become a cooling solution especially for portable and miniature devices with high heat generation. Till now, the research on microchannel devices are still focusing on heat transfer performance as the main objective but in the same time, pressure drop is another main issue to be solved where both parameters are contradicting to each other [1]. As the heat transfer performance increases, there will be high pressure drop which needs additional pumping system to overcome.…”

Thermal hydraulic performance of microchannel device is affected mainly by its geometrical parameter. The purpose of this study is to investigate the effect of multilayer microchannel arrangement to the thermal hydraulic performance of microchannel arrays. Numerical analysis was conducted to simulate three different microchannel arrangements by varying mass flow rate and heat flux imposed on the microchannel device. The simulation model is a simplified version which consists of eight microchannels in a single row and contains four layers for model one while model two has an arrangement of eight-seven-eight-seven microchannels in four layers and model three has an arrangement of seven-eight-seven-eight microchannels in four layers. The boundary condition that was set for heat flux ranged between 200 W/ 2 to 1000 W/ 2 while mass flow rate that flow into the device was varied between 20 kg/h to 80 kg/h. From the simulation result, it is shown that certain arrangement of microchannel in multilayer channels contribute to the enhancement of heat transfer and at the same time reducing the pressure drop of the system.

“…They reported that the optimization of vascular channel constructs could lead to much lower flow resistance and more uniform temperature distribution. Multi-scale multichannel devices, also named as Self-Similarity Heat Sinks (SSHS) with a multiscale arrangement of complex micro-structures have been proposed and investigated [31][32][33][34]. High heat removal capacity (heat flux up to 1000 W cm −2 ) could be achieved.…”
