Thermal Test of the Active Fluidic Cooling Unit of ATV 2003-01-2422

The Equipped Avionics Bay of the Automated Transfer Vehicle is thermally controlled by means of ten Active Fluidic Cooling Units (AFCU), each of them being composed of four Variable Conductance Heat Pipes (VCHP).
In spring 2002, a thermal test in vacuum chamber has been performed with one AFCU subsystem. The objectives were:
  • To characterize the thermal behavior
  • To tune the control architecture
  • To validate the AFCU modeling
This paper deals with the set-up, the means and the sequence implemented for this test and the main results obtained from test measurements and exploitation.
