Methodology of optimization for microchannel heat exchanger
Twenty-Second Annual IEEE Semiconductor Thermal Measurement And Management Symposium, 2006Heat generation from very large-scale integrated (VLSI) circuits increases with the advent of high-density integrated circuit technology. One of the promising techniques is liquid cooling by using microchannel heat exchanger. This work proposes a scheme for microchannel heat exchanger optimization with the constraint of pump. The cooling performance of

Extruded Microchannel-Structured Heat Exchangers
Heat Transfer Engineering, 2004In the search for more compact air/liquid heat exchangers, one possible way is to increase the heat transfer coefficient and surface area by a decrease of the size of the fluid channels. A practical example could be air/water cross-flow heat exchangers used in cars. These exchangers are designed so that air pressure drop is minimised at a given thermal

Heat Exchange Characteristics of a Gas-Gas Counterflow Microchannel Heat Exchanger
Volume 10: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B, and C, 2008Heat exchange characteristics of a gas-gas counterflow microchannel heat exchanger have been investigated experimentally. The microchannel has a rectangular cross section with 200 μm high and 300 μm wide. Working fluid is air. Reynolds number in the hot passage ranges from 127 to 381, and that in the cold passage ranges from 25 to 381. Temperatures and

Exergy analysis of microchannel heat exchangers
International Journal of Exergy, 2020This study investigates the exergetic efficiencies of four plain microchannel heat exchangers under single-phase and two-phase flow conditions using de-ionised water as the working fluid. The friction factor and heat transfer coefficient data of microchannels are obtained using experimental studies from the literature.

Constructal design of subcooled microchannel heat exchangers
International Journal of Heat and Mass Transfer, 2020Abstract This paper presents geometric optimization and flow parameters modelling for subcooled flow boiling (two-phase flow). The objective of the paper was to minimize the thermal resistance of the microchannel heat exchanger subject to fixed volume constraints of heat sink and microchannel.

Development of a Microchannel Heat Exchanger for Aerospace Applications
ASME 2012 10th International Conference on Nanochannels, Microchannels, and Minichannels, 2012Honeywell Aerospace has been developing microchannel heat exchangers for aerospace use. These heat exchangers offer significant reduction in volume and some reduction in weight compared to state-of-the-art aerospace heat exchangers constructed using offset plate and fin interupted surfaces.
