Optimization of Heat Exchange in Manifold-Microchannel Grooves
Journal of Heat Transfer, 2018Manifold-microchannel (MM) combinations used on heat transfer surfaces have shown the potential for superior heat transfer performance to pressure drop ratio when compared with chevron-type corrugations for plate (frame) heat exchangers (PHEs). This paper presents an advanced genetic algorithm (GA)-based procedure for analyzing and optimizing the MM ...

High power density air-cooled microchannel heat exchanger
International Journal of Heat and Mass Transfer, 2018Abstract We present single-phase heat transfer in a compact cross-flow microchannel heat exchanger, with air flowing through the heat exchanger to remove heat from a closed-loop flow of refrigerant R245fa. The 1 cm3 heat exchanger was monolithically fabricated from a block of copper alloy using micro-electrical-discharge machining.

Modeling non-adiabatic parallel flow microchannel heat exchangers
International Journal of Thermal Sciences, 2011Abstract This article analyzes parallel flow microchannel heat exchangers with non-adiabatic thermal condition imposed on the wall separating the fluids and the ambient. For purposes of analysis, a thermal model comprising of two governing equations, one for each of the fluids, is developed and analytically solved to obtain equations for calculating ...

Constructal Design of Forced Convection Cooled Microchannel Heat Sinks and Heat Exchangers
ASME 3rd International Conference on Microchannels and Minichannels, Part B cont’d, 2005Heat transfer from arrays of circular and non-circular ducts subject to finite volume and constant pressure drop constraints is examined. It is shown that the optimal duct dimension is independent of the array structure and hence represents an optimal construction element.

Modeling non-adiabatic counter flow microchannel heat exchangers
Applied Thermal Engineering, 2013Abstract This article presents a thermal model of counter flow microchannel heat exchangers that are subjected to thermal interaction with its surroundings (ambient or substrate or neighboring microdevices) due to its non-adiabatic outer wall. The thermal model consists of two governing equations, one for each of the fluids, describing the variation ...
