Numerical methods are used to study the effect of changing the internal configuration of microchannels on heat and mass transfer. The numerical models were validated by comparing them with the results of laboratory experiments using microfluidic chips. Graphs are presented for the dependence of the average temperature and volumetric flow rate on the pressure drop across the channel cross-section, velocity distributions, and temperature fields within the channels. The study demonstrated that the identified effects of changing the arrangement of columns within the microchannel and the fluid injection mode on the hydrodynamic and thermophysical parameters of the system can be used in the design of microheat sinks.. Keywords: microheat sink, silicon microchannel, heat and mass transfer, microfluidics.
