Summary

Airbus Defence and Space Netherlands (ADSN) has developed thermal straps that are optimized for space applications and can be used on a wide range of missions, from one-offs to mega constellations.

A HiPeR Flexlinks consists of thin sheets of Pyrolytic Graphite (PG) that transfer heat in-plane efficiently without a significant out-of-plane heat loss. The stack of PG sheets is sandwiched between metal plates, which also act as thermal interface to the surrounding structure.

Because the PG material can release small particles, a sleeve made of a unique mesh material is wrapped around the stack to enclose the PG. This ensures no particle contamination, yet allows ventilation while maintaining the overall flexibility.

With HiPeR Flexlinks, a thermal conductive link between two interface points can be created, while keeping these interfaces mechanically decoupled. The flexibility of the link (stiffness < 1.5 N/mm in all three axes) enables freedom in the spacecraft design, without compromising thermal and mechanical performance.

Key characteristics of the HiPeR Flexlinks include:

  • Conductivity up to 3.6 W/K
  • Standard M4 connections
  • 120 gr for typical 1 W/K thermal straps
  • Suitable for clean environments

The end-fitting configuration options are:

  • PAR-PAR; PER-PER or PAR-PER
  • Same or Opposite direction
