Analysis of microchannel heat exchangers using FEM
International Journal of Numerical Methods for Heat & Fluid Flow, 2001A finite element method is applied to evaluate the performance of microchannel heat exchangers that are used in electronic packaging. The present approach is validated against the CFD data available in the literature. A comparison of the predicted results with other available results obtained from different concepts shows that the present method is ...

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 ...

Exergy analysis of microchannel heat exchangers
2022This 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.

Numerical Simulation of Manifold Microchannel Heat Exchanger
Volume 8: Heat Transfer and Thermal Engineering, 2016The quest to achieve higher heat transfer rate, smaller size and minimum pressure drop is a main area of focus in the design of heat exchangers. Plate heat exchangers are one of viable candidates to deliver higher heat duties but still have a drawback of higher pressure drop due to long restricted flow path.

Axial Heat Conduction in Parallel Flow Microchannel Heat Exchangers
Volume 9: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B and C, 2009This paper deals with the effect of axial heat conduction on the hot and cold fluid effectiveness of a balanced parallel flow microchannel heat exchanger. The ends of wall separating the fluids are subjected to Dirichlet boundary condition. This leads to heat transfer between the microscale heat exchanger and its surroundings and thereby leading to ...

Axial Heat Conduction in Counter Flow Microchannel Heat Exchangers
Heat Transfer: Volume 2, 2008This paper analyzes the effect of axial heat conduction on the thermal performance of a balanced counter flow microchannel heat exchanger. The ends of the wall separating the coolants are subjected to the mixed-boundary condition. Analytical equations were developed for predicting the axial temperature of the fluids and the wall as well as the ...
