Abstract
Due to the rapid development of the microelectronic industry, new efficient cooling systems are required. The most promising is the liquid cooling technology with the introduction of cooling devices directly into the microelectronic chips. In this paper, we study the liquid flow and its integral characteristics in microchannels with pin fin arrays. Various internal geometries of microchannels are considered, including both uniformly distributed cylindrical pins and systems with two packing scales. The effect of changing the pin spatial distribution in microchannels with the same void coefficient on the flow rate variation, velocity field and temperature distribution is shown. The results obtained can be used in the design of microfluidic heat sinks.
期刊介绍:
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
