Abstract

<p>SE PROPORCIONA UN SISTEMA (1) Y MÉTODO DE REFRIGERACIÓN PARA ENFRIAMIENTO A DISTANCIA DE UNA CARGA TÉRMICA TENIENDO UNA PRIMERA PORCIÓN (27) Y UNA SEGUNDA PORCIÓN (25). EL SISTEMA COMPRENDE UNA FUENTE DE FRÍO (4) TENIENDO UNA PRIMERA ETAPA DE ENFRIAMIENTO (5) Y UNA SEGUNDA ETAPA DE ENFRIAMIENTO (6), LA TEMPERATURA DE LA PRIMERA ETAPA DE ENFRIAMIENTO SIENDO MAYOR QUE LA TEMPERATURA DE LA SEGUNDA ETAPA DE ENFRIAMIENTO. EL SISTEMA TAMBIÉN COMPRENDE UN CIRCUITO CRIOGÉNICO PARA CIRCULACIÓN DE UN FLUJO DE CRIÓGENO EN UN CICLO CERRADO, EL CICLO CERRADO SIENDO ACOPLADO DE MANERA TÉRMICA A LA FUENTE DE FRÍO. EL SISTEMA ADEMÁS COMPRENDE UN COMPRESOR (7) PARA COMPRIMIR Y CIRCULAR EL FLUJO DE CRIÓGENO EN EL CIRCUITO CRIOGÉNICO. EL CIRCUITO CRIOGÉNICO COMPRENDE UN PRIMER CONDUCTO PARA CONECTAR DE MANERA TÉRMICA LA PRIMERA ETAPA DE ENFRIAMIENTO DE LA FUENTE DE FRÍO A LA PRIMERA PORCIÓN DE LA CARGA TÉRMICA DE MANERA DE ENFRIAR DICHA PRIMERA PORCIÓN HACIA LA TEMPERATURA DE LA PRIMERA ETAPA DE ENFRIAMIENTO, Y UN SEGUNDO CONDUCTO PARA CONECTAR DE MANERA TÉRMICA LA SEGUNDA ETAPA DE ENFRIAMIENTO DE LA FUENTE DE FRÍO A LA SEGUNDA PORCIÓN DE LA CARGA TÉM1ICA DE MANERA DE ENFRIAR DICHA SEGUNDA PORCIÓN HACIA LA TEMPERATURA DE LA SEGUNDA ETAPA DE ENFRIAMIENTO. EL FLUJO DE CRIÓGENO EN EL SISTEMA ES UN FLUJO DE GAS DE HELIO SÚPER CRÍTICO, LÍQUIDO SUB-ENFRIADO O SATURADO, DE DOS FASES, SATURADO O SOBRECALENTADO.</p><p> A SYSTEM (1) AND REFRIGERATION METHOD FOR COOLING DISTANCE FROM A THERMAL LOAD IS PROVIDED WITH A FIRST PORTION (27) AND A SECOND PORTION (25). THE SYSTEM INCLUDES A COLD SOURCE (4) HAVING A FIRST COOLING STAGE (5) AND A SECOND COOLING STAGE (6), THE TEMPERATURE OF THE FIRST COOLING STAGE BEING GREATER THAN THE TEMPERATURE OF THE SECOND COOLING STAGE. THE SYSTEM ALSO INCLUDES A CRIOGENIC CIRCUIT FOR CIRCULATION OF A CRYGEN FLOW IN A CLOSED CYCLE, THE CLOSED CYCLE BEING COUPLED THERMALLY TO THE COLD SOURCE. THE SYSTEM ALSO UNDERSTANDS A COMPRESSOR (7) TO COMPRESS AND CIRCULATE THE CRIOGEN FLOW IN THE CRIOGENIC CIRCUIT. THE CRIOGENIC CIRCUIT UNDERSTANDS A FIRST CONDUCT TO CONNECT THE FIRST COOLING STAGE OF THE COLD SOURCE TO THE FIRST PORTION OF THE THERMAL LOAD OF COOLING THE SUCH FIRST PORTION TO THE TEMPERATURE OF THE FIRST STAGE, IN THE FIRST STAGE, IN THE FIRST STAGE CONDUCT TO CONNECT THERMALLY THE SECOND COOLING STAGE OF THE COLD SOURCE TO THE SECOND PORTION OF THE THERMAL LOAD WAY TO COOL SUCH SECOND PORTION TO THE TEMPERATURE OF THE SECOND COOLING STAGE. THE CRYOGEN FLOW IN THE SYSTEM IS A SUPER CRITICAL HELIO GAS FLOW, SUB-COOLED OR SATURATED LIQUID, TWO-PHASE, SATURATED OR OVERHEATED. </p>
