Cooling system for aircraft powerplant electronics

An assembly for an aircraft powerplant, comprising:

• a first electric device including a first device housing and first electrical circuitry housed within an interior of the first device housing;
• a second electric device including a second device housing and second electrical circuitry, the second electrical circuitry housed within an interior of the second device housing;
• a cooling system configured to cool the first electrical circuitry and the second electrical circuitry, the cooling system comprising a first heat exchanger disposed laterally between and thermally coupled to the first electric device and the second electric device;
• and
• a vane structure, wherein at least the first electric device and the first heat exchanger are disposed within the vane structure.

An assembly for an aircraft powerplant, comprising:

• a first electric device including a first device housing and first electrical circuitry housed within an interior of the first device housing;
• a cooling system configured to cool the first electrical circuitry, the cooling system including a first heat exchanger, an air circuit and a closed loop fluid circuit, the first heat exchanger configured to transfer heat energy between air flowing in the air circuit and a working fluid flowing in the closed loop fluid circuit, the first electric device mounted to a side of the first heat exchanger, the air circuit extending through the first heat exchanger, the closed loop fluid circuit extending through the first heat exchanger and the first electric device, the closed loop fluid circuit thermally coupled to the first electrical circuitry, and the closed loop fluid circuit comprising a pump configured to circulate the working fluid;
• and
• a vane structure, wherein at least the first electric device and the first heat exchanger are disposed within the vane structure.
