MODEL OF COOLING OF COMPACT SURFACES BY MICROCHANNEL RECUPERATIVE HEAT EXCHANGERS WITH A MATRIX OF FILAMENTARY SILICON SINGLE CRYSTALS

An analysis has been made of a novel class of recuperative heat exchangers for cooling of compact surfaces in electronic systems for various object-oriented purposes with a matrix of fi lamentary silicon single crystals grown directly on the heat-liberating boundary. A mathematical model has been proposed based on the assumption of the regime of ideal displacement of the heat-transfer agent in the form of a system of equations of two-temperature convective heat transfer with volume averaging over the element in a porous skeleton. The solution of the system has been obtained in analytical form. The experiment conducted on a pilot plant has confi rmed the adequacy of the mathematical model
