Abstract

The present paper focuses on cooling systems, based on Joule-Thomson effect, that include condensers and vaporizers, having the role of eliminating the heat flux generated by electronic components. Temperature reduction is ensured by an isenthalpic expansion of refrigerating agent in the laminating element. As technology evolved, mini heat exchangers developed today use micro and nano-channels. Better understanding of phenomena occurring within these devices is therefore required. The present paper illustrates results obtained for a mini heat exchanger having rectangular microchannels with a transversal section of 40 μm by 0,35 mm. Mini heat exchanger plates illustrated in this paper were built using a method developed in the Heat Transfer Laboratory from the Suceava University. The refrigerating agent employed was R12 Freon.
