SADDLEBACK AEROSPACE - Compact Heat Exchangers
Saddleback's compact heat exchangers use a laminated foil construction
to reduce the core size and weight of Liquid/Liquid and Liquid/Air heat
Advantages of Laminated Foil Heat Exchangers
- Improved Thermal Performance
- Reduced Scale of Passages Yields Higher Heat Transfer Coefficients
- Large Heat Transfer Area Per Unit Volume
- Compact Construction
- 5X Core Depth Reduction Compared to Conventional Concepts
- 3X Weight Reduction
- Robust Construction
- Laminated Foil Heat Exchangers Use a Reinforced, Robust Construction
- Almost Any Metal Can be Used (Cu, Al, SS, Superalloys, etc.)
- Structures Can be:
- Soldered (Low Cost)
- Brazed (for Aluminum)
- Diffusion Bonded (Higher Strength, Longer Fatigue Life, Reduced
Current/Previous Heat Exchanger Development Programs
- Advanced Integrated Fuel System (Current)
- Saddleback is currently under contract to Northrop/SPARTA to design and fabricate
an Inconel 718 Fuel/Bleed Air heat exchanger sized to reject 14700 Btu/min.
This radiator is designed to operate at extreme temperatures (~ 1000F)and
internal pressures (1300 psi), and must be
packaged in an extremely restricted volume. At least one prototype will be built
and tested by March '96. AMITA ,
a partner of Saddleback, has developed the necessary superalloy fabrication processes
and will be manufacturing the prototypes.
- Unmanned Aerial Vehicle Heat Exchanger (1992)
- Saddleback employees designed, built and tested a prototype heat exchanger for the
Propulsion Engineering Directorate of the Naval Air Warfare Center. The air/engine
coolant heat exchanger was designed to cool a 150 HP UAV engine, dissipating
50 HP (3300 Btu/min) of waste heat. Analytic trade studies produced a final design
which was 18" x 18" x 0.5", and weighed only 5 lbs.

built for NAWC.
- Advanced Amphibious Assault Vehicle Land Mode Radiator (1991)
- Saddleback employees designed, built and tested a prototype radiator for David Taylor
Research Center. The air/engine coolant radiator was sized to reject 28400 Btu/min.
The baseline high performance aluminum radiator was 34" x 34" x 6" and weighed 217 lbs;
the Saddleback version had a core depth of only 1.8" and weighed only 70 lbs. Eight
subscale prototypes were built and tested, confirming the design calculations.
