摘要
The radiator with two estu00c1gios emitu00c2ncia tender for use in vacuum. The present invention relates to a radiator for heat dissipation by radiative exchange consists of two stages, internal and external. The stages are connected physically through insulating washers to eliminate or minimize the exchange of heat by conduction between them.The internal surfaces of the two stages are aletadas and covered with a coating that has the value of its thermal emissivity dependent on temperature. The outer surface of the outer stage is covered with material with low absortividade in the solar spectrum. The emissivity of outer surface in the spectrum mfravermelho can either be constant and high as variable as a function of temperature.The function of the stage is to receive heat from a single source dissipator, while external is to reject this heat to the environment. The heat exchange between the two stages is primordialinente by radiation between their internal surfaces.As the emissivity of coating of the same is directly proportional to the temperature of the supefficies, the present invention works as a kind of valve between the source and the heat dissipator environment, allowing an automatic control and the liabilities of the temperature of the source.
