  • Heat transfer system for a satellite including an evaporator
    Patent number: 7174950
    Abstract: A heat transfer system includes a heat transfer passage in the vicinity of a source of dissipated heat on a satellite to collect heat dissipated by the source and a fluid loop including an evaporator having over part of its path a maximum surface area of its external walls in contact with external walls of the heat transfer passage.
    Type: Grant
    Filed: May 29, 2003
    Date of Patent: February 13, 2007
    Assignee: Alcatel
    Inventors: Bernard Jacqué, Emmanuel Texier, Gérard Cluzet, Tisna Tjiptahardja, Marcel Amidieu
  • Satellite comprising means for transferring heat from a shelf supporting equipment to radiator panels
    Patent number: 7118076
    Abstract: A satellite, in particular a telecommunication satellite, comprises a structure having a north face and a south face that are oriented perpendicularly to the rotation axis of the Earth and an east face and a west face that are periodically exposed to solar radiation as the satellite orbits the Earth. The structure supports equipment dissipating heat, the north, south, east and west faces constituting radiator panels that radiate into space heat dissipated by the equipment.

  • Heat transfer device
    Patent number: 6626231
    Abstract: A heat transfer device includes a capillary-pumped first fluid loop including an evaporator situated on a satellite in the vicinity of a source of dissipated heat and a condenser connected by heat transfer members to the evaporator and situated on a deployable radiator panel of the satellite. The deployable radiator comprises at least two panels, and the heat transfer device itself further comprises at least one second capillary-pumped fluid loop. The fluid loops are connected in cascade with each other so that the evaporator of each fluid loop other than the first fluid loop is on the same panel as the condenser of the preceding loop and the condenser of each fluid loop other than the first fluid loop is on the panel next to that carrying the condenser of the first loop. The evaporator of one loop is connected to the condenser of the same loop by flexible heat transfer members.
