In the Study of performance of heat transfer in microchannel heat sinks used for cooling electronic chips

the available methods mostly assume microchannel sinks with uniform heat flux distribution.Finite element method

which can analyze microchannel heat sinks with non-uniform heat flux distribution

is presented.Compared with the results derived from existing methods for instance massive Calculated Fluid Dynamics calculations

in spite of arbitrary heat flux distribution occurred

heat transfer performance about microchannel heat sinks can be analyzed efficiently and more rapidly by the finite element method presented in this paper.A Galerkin finite element formulation has been used to predict the surface temperature

the fluid temperature and the total thermal resistance of the microchannel heat sinks with different heat flux distribution

finite element method is used to study the effect of geometrical parameters on the performance of the microchannel heat sinks at last.
