Abstract

METODO Y APARATO PARA ENFRIAR UNA FIBRA OPTICA EXTRAIDA POR ESTIRADO A PARTIR DE UNA PREFORMA DE CRISTAL CALIENTE, MEDIANTE EL PASO DE LA FIBRA (3) A TRAVES DE UN CONDUCTO DE ENFRIAMIENTO (9) POR EL CUAL FLUYE UN GAS DE ENFRIAMIENTO (A) EN LA DIRECCION AXIAL DE LA FIBRA Y ALREDEDOR DE LA MISMA. PARA REDUCIR EL CONSUMO DE GAS DE ENFRIAMIENTO, ESTE ULTIMO SE HACE FLUIR TURBULENTAMENTE (B) ALREDEDOR DE LA FIBRA POR MEDIO DE UN PUNTO DE ESTRANGULAMIENTO (20) FORMADO POR UNA PARED DIVISORIA (19) EN EL CONDUCTO DE ENFRIAMIENTO, DE MODO QUE SE IMPIDA EL FLUJO LAMINAR DEL GAS DE ENFRIAMIENTO ALREDEDOR DE LA FIBRA Y SE MEJORE LA TRANSFERENCIA DE CALOR ENTRE EL GAS DE ENFRIAMIENTO Y LA FIBRA.
