Abstract

PROCEDIMIENTO PARA ENFRIAR PIEZAS DE TRABAJO POR INTERCAMBIO TERMICO DIRECTO CON UN GAS LICUADO DE BAJO PUNTO DE EBULLICION. CARACTERIZADO PORQUE AL GAS LICUADO DE BAJO PUNTO DE EBULLICION SE LE INCORPORAN MATERIAS SOLIDAS EN FORMA DE PARTICULAS MICROSCOPICAS QUE, POR RAZON DE SU PESO ESPECIFICO, FLOTAN EN EL GAS LICUADO O POR LO MENOS SE MENTIENEN EN SUSPENSION POR LAS TURBULENCIAS GENERADAS EN EL GAS DE EBULLICION. DE APLICACION EN EL ENFRIAMIENTO DE PIEZAS METALICAS DE TRABAJO POR INTERCAMBIO TERMICO DIRECTO CON NITROGENO LIQUIDO.
