HYDRODYNAMICS AND HEAT TRANSFER IN MINICHANNEL COOLING SYSTEMS OF LASER MIRRORS

Consideration has been given to some issues of application of multilayered cooling systems with minichannels in laser mirrors and chips. Generalized results are presented for experimental investigations of hydraulic resistance and heat transfer in minichannel cooling systems with rough walls in a broad range of variation of the Reynolds number (2·10¹ < Re < 4·10⁴ ). A comparison has been made of the obtained results with the existing relations, and signifi cant deviations have been detected in the hydraulic resistance of rough channels from that of smooth ones in a laminar fl ow regime
