Filed:

Nov 15, 2021

Appl. No.:

17/454984

Inventors:

- Indianapolis IN, US
Eric Donovan - Indianapolis IN, US

Assignee:

Rolls-Royce North American Technologies Inc. - Indianapolis IN

International Classification:

H05K 7/20

Abstract:

An electronics cabinet cooling system may include multiple cabinet heat exchangers mounted at an air discharge of respective different electronic cabinets. Heat from a flow of air heated by electronic components in the electronic cabinets may be received by respective cabinet heat exchangers. A liquid refrigerant flowing through the heat exchangers in parallel may be at least partially changed from liquid to gas and absorb the heat from the flow of air. A three-way tee in a common outlet header downstream from the cabinet heat exchangers may direct the gas refrigerant to a condenser and the liquid refrigerant to a receiver. The condenser may condense the gas refrigerant to liquid refrigerant, which may be routed to the receiver.

Abstract:

Systems and methods for thermal management are provided. Thermal management components may include an electrical source and a cooling source. The electrical source may supply electricity to an electrical apparatus. In addition, the thermal management components store thermal energy. A controller may cause the electrical apparatus to be cooled by the cooling source and delay or suspend cooling the electrical source with the cooling source while a state of charge of the electrical source is greater than a predefined value for the electrical source. The state of charge of the electrical source may include a measurement of cooling capacity available by the electrical source.

Abstract:

Systems and methods for suppressing infrared radiation generated by a turbine engine. A system comprises a primary assembly having a center body, a plurality of vanes extending from the center body, an outer radial duct with the plurality of vanes extending therethrough, a structural baffle, and a mixer. The primary assembly is disposed in the exhaust flow path of a turbine engine and encased in ducting and/or an airfoil. An air flow path defined between the center body and outer radial duct is axially spit by an interface rim and flow segregator. The flow segregator segregates engine core flow from ambient air flow.
