Function
The fuel cooler is installed in the fuel return line between the engine and the fuel tank.
Uncombusted, heated fuel (a) flows through the fuel inlet (5) into the heat exchanger (4). Air (b) drawn
through an aluminum radiator block by a centrifugal fan (6) withdraws heat from the fuel. After passing
through the heat exchanger (4) comprising a pipe bundle, the air-cooled fuel is returned to the fuel tank via
the fuel outlet (2).
The centrifugal fan (6) is driven by an electric motor (3). The air (b) is drawn into the housing of the fuel
cooler (1) by the rotating blades of the fan. Heated air exits the fuel cooler after cooling the fuel in the heat
exchanger.
