An air conditioning system 20 is provided with a cooling air ram that includes both air-to-air heat exchangers 28, 34, and a liquid sink heat exchanger 40. The liquid sink heat exchanger 40 receives a cooling fluid that has been utilized to cool a power electronics control 42 for an electric motor 43. The liquid sink heat exchanger 40 is necessary to properly cool the power electronics control 42, and by including it in the same cooling air ram with the air-to-air heat exchangers 28, 34, there is no need for additional ram air cooling circuits to be added to the gas turbine engine. |
