Summary[edit]
| Description |
Français : Modélisation des échanges thermiques du télescope spatial infrarouge Spitzer.
La chaleur est produite par le rayonnement solaire qui vient frapper les panneaux solaires (à droite) et l'électronique du module de service en bas sur le schéma. Elle se diffuse vers le télescope et ses instruments par conduction (via les entretoises qui solidarisent les différents composants) et par rayonnement. Deux boucliers thermiques interceptent et évacuent dans le vide par rayonnement la majeure partie de la chaleur produite. La chaleur est progressivement bloquée par l'enveloppe externe et les enceintes du vase Dewar qui entourent le télescope et ses instruments. L'hélium en s'évaporant évacue le peu de chaleur (4 mW) qui parvient jusqu'au coeur du télescope maintenu à 5,5 Kelvin ou qui est produite par les détecteurs des instruments. |
