Integrated HP Radiator

EW JET's integrated heat pipe radiators use 3D-printed aluminum-ammonia heat pipes embedded directly into the radiator structure. Available in 2-bore, 3-bore, and 4-bore configurations with 8mm or 17mm core diameters, allowing precise matching of heat transport capacity to mission heat rejection requirements.

Technology

3D-Printed Heat Pipe Integration

Aluminum-ammonia heat pipes are 3D-printed directly into the radiator body — no bonding, no interface resistance, fully monolithic panel construction.

Bore & Core Selection

Choose 2, 3, or 4 bore configurations combined with 8mm or 17mm core diameters to precisely match heat transport capacity to mission heat rejection requirements.

Heat Spreading Uniformity

Multiple bores running the full length of the panel ensure uniform temperature distribution across the radiating surface, preventing local hot spots.

NH₃ Sealed System

Ammonia working fluid provides high latent heat capacity across the operational temperature range — sealed at manufacture, maintenance-free for mission life.

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.

Bore Configurations

Select the number of bores to match your heat rejection capacity requirement.

2
2-Bore

Compact two-bore configuration for moderate heat loads.

3
3-Bore

Balanced three-bore layout for medium spacecraft payloads.

4
4-Bore

High-capacity four-bore design for demanding heat rejection requirements.

Core Diameter Options

Each bore configuration is available in 8mm or 17mm core diameter.

8mm
8mm Core

Smaller profile core — ideal for volume-constrained designs and micro/nanosatellites.

17mm
17mm Core

Larger core diameter for higher conductance and greater ammonia charge volume.
