摘要
A cryogenic device is provided which is intended for cooling components 2 which are sensitive to temperature, especially to infrared radiation. The device incorporates closed-circuit main cryogenic means 3, capable of producing temperatures below or equal to approximately 210 DEG K and having a coefficient of performance (COP) between 1% and 20%, preferably between 2% and 10%, and having at least one hot zone Qc1, Tc1, and Peltier-effect or Ettinghausen-effect supplementary electronic cooling means 32, having a cold area thermally connected to said hot zone.
