Methodology of optimization for microchannel heat exchanger

Twenty-Second Annual IEEE Semiconductor Thermal Measurement And Management Symposium, 2006
Heat 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, 2004
In 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

Exergy analysis of microchannel heat exchangers

International Journal of Exergy, 2020
This 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.

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, 2008
Heat 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
