Heat pipes numbers:
- 8 Constant Conductive Heat Pipes ( BCCHP ) integrated in the Avionic Bay (EAB) battery panels and connected to the BVCHP network
- 8 Battery Variable Conductance Heat Pipes ( BVCHP ) to control the batteries temperature and to reject battery heat load to EAB radiator
- 32 Avionics Variable Conductance Heat Pipes ( AVCHP ) dedicated to the heat control of other equipment of the EAB
- 4 Constant Conductive Heat Pipes ( PCCHP ) dedicated to transfer heat load from the Propulsion Drive Electronic box in the Propulsion Bay (EPB)

Heat pipes types:
VCHP and PCCHP
- Container: stainless steel heat pipes
- Capillary structure: metallic Wick
- Fluid: Ammonia
- Interface through aluminium saddles brazed on the heat pipe tube.
- Control: Nitrogen is set into the VCHP in order to control its transfer function by controlling the reservoir temperature.
BCCHP
- container: aluminium extruded heat pipes
- capillary structure: re-entrant grooves
- fluid: ammonia

Qualification phase
During the design and qualification phase (from end of 2000 to May 2002), 120 Heat Pipes (including 2 full batches of 52 items) have been designed, built, tested and delivered to EADS Astrium for ground tests and for the ATV Jules Verne. This has represented a big challenge in term of specification, design, manufacturing and test in a very short planning that has been successfully achieved thanks to a real collaboration between EADS Astrium, SABCA, ESA and EHP teams dedicated to the heat pipes.

Production phase
From 2004 EHP has already delivered the 2 first heat pipes batches for the recurring ATV's and the manufacturing of heat pipes dedicated to the 3 rd ATV to be launch is on going.
