Structural + Thermal
Honeycomb Panel Radiator
EW JET honeycomb panel radiators serve a dual role: structural panel and thermal management system. Available in 1U, 2U, and 3U configurations with multiple embedded heat pipes, these panels reduce overall satellite mass by combining structural and thermal functions into a single component.
Technology
Structural Panel
The honeycomb core provides the mechanical stiffness and load-bearing capability required as a satellite face panel, meeting structural requirements without dedicated structural members.
Thermal Management
Multiple AL-NH₃ heat pipes embedded within the honeycomb spread and reject waste heat to space simultaneously — no separate radiator panel needed.
Mass Savings
Combining structural and thermal functions into one component eliminates the mass of separate radiator panels and mounting hardware, improving payload mass fraction.
Heat Pipe Density
Multiple heat pipes per panel ensure uniform temperature distribution across the radiating surface, preventing hot spots and maximising rejection efficiency.
Applications
GEO Communication Satellites
Long-duration missions with steady payload heat loads. Heat pipe panels provide reliable, maintenance-free rejection for 15+ year lifetimes.
LEO / SAR Payloads
Rapid orbital thermal cycling and pulsed high-power SAR operation — heat pipe integration handles transient and steady-state loads.
CubeSat & SmallSat
1U–3U honeycomb panels serve as both structural face sheets and thermal radiators — eliminating dedicated radiator mass from the satellite bus.
Panel Sizes
Available in 1U, 2U, and 3U CubeSat-compatible formats with embedded heat pipe networks.
100 × 100mm panel. Single-unit CubeSat compatible face panel with embedded heat pipe network.
100 × 200mm panel. Extended heat rejection area for 2U and larger satellite platforms.
100 × 300mm panel. Full 3U face panel — maximum heat pipe density and rejection capacity.
