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.

1U
1U Panel

100 × 100mm panel. Single-unit CubeSat compatible face panel with embedded heat pipe network.

2U
2U Panel
