Abstract
A cooling system for a gas turbine engine may comprise a plenum extending circumferentially around an outer engine case structure. The plenum may comprise a supply conduit and a return conduit. The supply conduit and the return conduit may be in fluid communication with a heat exchanger. The heat exchanger may be disposed between the outer engine case structure and an inner engine case structure. The plenum may be configured to provide enhance heat transfer for the cooling system.
Claims15
A cooling system for a gas turbine engine, comprising:
- an outer engine case structure;
- an inner engine case structure disposed radially inward of the outer engine case structure, the inner engine case structure and the outer engine case structure defining a bypass duct;
- a heat exchanger disposed between the outer engine case structure and the inner engine case structure;
- a supply conduit disposed radially outward of the outer engine case structure, the supply conduit extending circumferentially about the outer engine case structure, the supply conduit fluidly coupled to the heat exchanger;
- a return conduit disposed radially outward of the outer engine case structure and axially adjacent to the supply conduit, the return conduit extending circumferentially about the outer engine case structure, the return conduit fluidly coupled to the heat exchanger;
- an insultation configured to enclose the supply conduit and the return conduit, the insulation defining a plenum, the supply conduit and the return conduit disposed within the plenum;
- a first plurality of heat fins coupled to the supply conduit and extending from a first radially inner surface of the supply conduit, each heat fin in the first plurality of heat fins extending away from the outer engine case structure;
- and
- a second plurality of heat fins coupled to the return conduit and extending from a second radially inner surface of the return conduit, each heat fin in the second plurality of heat fins extending away from the outer engine case structure.
