Abstract
Abstract Cold generating apparatus, wherein it comprises a cold storage enclosure filled with a material having a solid-liquid transmission in the vicinity of the operating temperature of the apparatus, a first panel forming a radiating surface, whose radiation drops into at least one of the atmospheric windows, a substantially vertical second panel immersed in the material of the cold storage enclosure, a pipe in the form of a coil on each of the first and second panels, said pipes being connected by plastically deformable couplings to form a closed circuit and a certain quantity of a fluid which is vaporizable under the operating conditions of the apparatus within the closed circuit, the assembly constituted by the first and second panels, the closed circuit and the heat transfer fluid forming a device of the heat pipe type serving as a thermal diode which only transmits heat in the direction from the storage enclosure to the radiating surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
212 words
A cold generating apparatus, comprising a cold storage enclosure filled with a material having a solid-liquid transition in the vicinity of the operating temperature of the apparatus, a first condenser panel forming a radiating surface, whose radiation drops into at least one of the atmospheric windows, a substantially vertical second evaporator panel immersed in the material of the cold storage enclosure, a pipe in the form of a coil on each of the first and second panels, said pipe having an inlet and an outlet, the inlet of the pipe of each panel being connected to the outlet of the other panel by short and plastically deformable pipes, to form a closed circuit, the planes of said first and second panels forming a dihedral and a certain quantity of a fluid which is vaporizable under the operating conditions of the apparatus within the closed circuit, the assembly constituted by the first and second panels, the closed circuit and the heat transfer fluid forming a single panel device of the heat pipe type serving as a thermal diode which only transmits heat in the direction from the storage enclosure to the radiating surface and having openings in its central part which limits the heat conduction between the condenser panel and the evaporator panel.
