| 摘要 |
The present invention provides a heat exchange system for a closed loop fuel delivery system. The heat exchange system generally includes a first pump, a heat exchanger, a high pressure pump pressurizes fuel. The heat exchanger, which is located downstream of the first pump, receives the pressurized fuel flow. The high pressure pump, which is located downstream of the heat exchanger, delivers a predetermined amount of fuel flow to a jet engine. The circulating pump receives fuel flow downstream of the heat exchanger and recirculates the fuel flow upstream of the heat exchanger.
