Abstract

"APARELHO E PROCESSOS PARA RESFRIAMENTO CRIOGêNICO EM BAIXA PRESSãO, ESPECIFICAMENTE DE FIBRAS óPTICAS". São apresentados processos e aparelho para resfriamento de um objeto usando um fluido de transferência de calor. Um dos processos compreende as etapas de contatar o objeto com um fluido de transferência de calor compreendendo hélio como o componente principal, o objeto atravessando uma unidade de troca de calor possuindo uma extremidade de entrada de objeto e uma extremidade de saída de objeto; impedir o ingresso de contaminantes na extremidade de entrada e extremidade de saída da unidade de troca de calor usando um gás de vedação, o gás de vedação saindo com o fluido de transferência de calor para formar um gás de saída; compressão do gás de saída para formar um gás de reciclo comprimido, direcionamento do gás de reciclo comprimido para um separador de gás-líquido, formando assim um gás enriquecido com hélio, que funciona como o fluido de transferência de calor e um líquido enriquecido; e aquecimento do líquido enriquecido para formar um gás de vedação. O termo objeto inclui preformas de fibra óptica, peças elétricas, tais como, painéis de circuito, subconjuntos e circuitos integrados, peças metálicas, peças cerâmicas e semelhantes.
