Two micro heat exchangers, characterized by microchannels of 100x100 and 200x200 µm square cross sections, were designed for that purpose. The fluid used was deionized water and there was no phase change along the fluid circuit. The fluid pressure drop along the heat exchanger and the heat transfer were measured and corrections were made to isolate the contribution of the micro channels. The results were compared with the predictions of the classical viscous flow and heat transfer theory. The main conclusions show that the experimental results fit well with these theories. No effects of heat transfer enhancement or pressure drop increase were observed as a consequence of the small scale of the microchannelsapplication/pdfeng©ElsevierMicrochannelMicro-heat exchangerPressure dropHeat transferresearch articleIngeniería IndustrialFísica10.1016/j.ijheatmasstransfer.2009.06.034open access543323-245446International Journal of Heat and Mass Transfer52
