Abstract

CICLO DE REFRIGERAçãO DE SUB-AMBIENTE. De acordo com uma concretização da invenção, um método para refrigerar a estrutura de geração de calor disposta em um ambiente que tem uma pressão ambiente inclui o fornecimento de um refrigerante de fluido e a redução de (22) uma pressão do refrigerante para uma primeira pressão de sub-ambiente, na qual o refrigerante tem uma temperatura de ebulição menor do que uma temperatura da estrutura de geração de calor (12). O método também inclui trazer o refrigerante na primeira pressão de sub-ambiente para em comunicação térmica com a estrutura de geração de calor (12), de modo que o refrigerante ferva e vaporize para absorver, desse modo, o calor da estrutura de geração de calor. O método ainda inclui o aumento (14) de uma pressão do refrigerante vaporizado acima da primeira pressão de sub-ambiente para uma segunda pressão de sub-ambiente.SUB-ENVIRONMENT COOLING CYCLE. According to one embodiment of the invention, a method for cooling the heat generating structure disposed in an environment having an ambient pressure includes providing a fluid refrigerant and reducing (22) a refrigerant pressure to a first pressure. in which the refrigerant has a boiling temperature lower than a temperature of the heat generating structure (12). The method also includes bringing the refrigerant at the first sub-ambient pressure into thermal communication with the heat generating structure (12), so that the refrigerant boils and vaporizes to thereby absorb heat from the heat generating structure. heat. The method further includes increasing (14) a vaporized refrigerant pressure above the first sub-ambient pressure to a second sub-ambient pressure.
