Summary

The actual trend in miniaturization of thermal systems implies new theoretical and experimental researches on meso-micro-nano- scales behaviour of actual well-known macro-scale thermal processes. The main researches envisions the micro heat exchangers and chemical reactors (theoretical and experimental approaches on micro-scale heat and fluid flow), and the low cost based technologies in manufacturing of micro devices. The demonstrated results in the flow with heat transfer are at this moment contradictory: within the paper it tries to sketch the influence of miniaturization upon the irreversibility through heat and fluid flow inside miniaturized channels. The procedure involves actual well-known macro-scale heat transfer and pressure drops equations because there is a real lack of reliable information. In order to perform a complete thermodynamic analysis, it was applied the thermodynamic mathematical judgment to the case of heat exchanger passage entropy generation.
