Heat exchangers used in aircraft engines:
|
Type of
Heat Exchanger |
Function |
Example/Application |
|
Air-to-Air Heat Exchanger |
Transfers heat from hot compressed air to
cooler ambient air. |
Pre-cooler in jet engines, ECS cooling
systems. |
|
Air-to-Liquid Heat Exchanger |
Transfers heat from a hot liquid (e.g.,
engine oil) to cooler air. |
Oil coolers in gas turbine engines. |
|
Liquid-to-Liquid Heat Exchanger |
Transfers heat between two liquid fluids. |
Fuel-Oil Heat Exchanger (FOHE) for fuel
preheating and oil cooling. |
|
Recuperators (Regenerative HX) |
Captures waste heat from exhaust gases to
improve efficiency. |
Used in Auxiliary Power Units (APUs) and
experimental engines. |
|
Intercoolers |
Cools compressed air between stages in a
multi-stage compressor. |
Found in turbocharged aircraft engines. |
|
Radiators (Piston Engines) |
Uses airflow to cool liquid coolant in
piston engines. |
Found in liquid-cooled aircraft piston
engines. |
