POROUS HOLLOW FILAMENTS OF SYNTHETIC POLYMERS AND THEIR USE IN HEAT TRANSMISSION DEVICES

Abstract

Abstract Translated from French LA PRESENTE INVENTION CONCERNE DES FIBRES CREUSES EN POLYMERES SYNTHETIQUES, COMPORTANT 10 A 90 EN VOLUME DE PORES COMMUNIQUANT ENTRE EUX, ET QUI ONT UNE SURFACE AVEC DES PORES OUVERTS SELON LE BREVET PRINCIPAL FRANCAIS, MAIS DONT LES PROPRIETES DE CONDUCTIVITE THERMIQUE, DE TRANSMISSION OU DE TRANSFERT DE LA CHALEUR SONT AUGMENTEES. UTILISATION DE CES FIBRES CREUSES DANS LES ECHANGEURS DE CHALEUR. THE PRESENT INVENTION CONCERNS HOLLOW FIBERS OF SYNTHETIC POLYMERS, CONTAINING 10 TO 90 BY VOLUME OF PORES COMMUNICATING WITH THEM, AND WHICH HAVE A SURFACE WITH OPEN PORES ACCORDING TO THE MAIN FRENCH PATENT, BUT OF WHICH THE PROPERTIES OF CONDUCTIVITY, THERMAL TRANSMISSION OR TRANSMISSION HEAT TRANSFER ARE INCREASED. USE OF THESE HOLLOW FIBERS IN HEAT EXCHANGERS.
