k-Core® Radiator Panels — Ensuring Performance in Space

For critical thermal management needs, including heat dissipation requirements of ≥ 40°C reduction, communications satellite and spacecraft engineers turn to k-Core passive thermal radiators. They offer a versatile, specialty engineered material, annealed pyrolytic graphite (APG) for reliable performance.

APG thermal radiator panelEfficient heat dissipation to protect critical electronic components in space, under increasingly tight space requirements, is performed by k Technology's k-Core passive thermal radiators, an example of the many Aavid Thermacore satellite thermal solutions.

k Technology thermal radiators incorporate a proprietary concept featuring APG, a highly ordered crystalline material with a thermal conductivity of >1,500 W/m-K, within a high-strength structural shell material such as aluminum or carbon polymer composite. The thermal performance of each material is kept separate, with no shear force transferred across the encapsulant/APG interface.

Radiator Panel Benefits

  • Reliable performance under a extreme temperatures (-40°C to +72°C)
  • Thermal performance without the need for heat pipes (which require difficult semiconductor-heat spreader CTE matching)
  • Rugged construction stands up to vibration launch loads and other stresses/pressures
  • Reduced product cost, increased reproducibility
  • Reduced size and weight, appropriate for the increasing density of electronic equipment and more limited space for thermal solutions
  • Ability to dissipate high heat fluxes produced by next-generation spacecraft electronics
