This paper presents the results of an experimental study related to characterisation of a mini channel heat exchanger. Such heat exchanger may be used in water cooling of electronic components. The results obtained show the efficiency of this exchanger even with very low water flow rates. Indeed, in spite of the importance of the extracted heat fluxes which can reach about 50 Kw/m2, the temperature of the cooled Aluminium bloc remained always lower than the tolerated threshold of 80°C in electronic cooling. Moreover, several thermal characteristics such as equivalent thermal resistance of the exchanger, the average internal convective heat transfer coefficient and the increase in the temperature of the cooling water have been measured. The results presented have been obtained with in "quinconce" rectangular mini-channel heat exchanger, with a hydraulic diameter Dh = 2 mm.
