Test
These
common passive thermal devices
are used to control spacecraft temperatures and
do not require heaters, active mechanical or active
fluid mechanisms.
Passive
Radiators
are windows of low resistance material, like glass,
on a spacecraft surface that increase emissivity
thereby releasing heat.
Multilayer
insulation (MLI)
is literally a gold or silver space blanket made
of Mylar or Kapton wrapped around a spacecraft to
control absorptivity and emissivity. It protects
from incident solar energy and channels internal
heat to radiators.
Simple
heat pipes
are sealed tubes that transfer
heat from hot components through fluid phase change
and capillary motion.
