The phase change thermal capacitor stores undissipated heat in a phase transition of a phase change material. | 08-16-2012 |
20120255711 | THERMAL ACCUMULATOR AND METHOD OF USE - A thermal management system for a vehicle includes a tank, a heat exchanger, a pump, and a valve located on a conduit. The heat exchanger is located downstream of the tank, the pump is located between the tank and the heat exchanger, and the valve is located downstream of the heat exchanger. The heat exchanger places the coolant in a heat exchange relationship with a heat load from the vehicle such that the coolant vaporizes. The valve regulates pressure within the heat exchanger and controls exhaustion of the vaporized coolant from the vehicle. Water, used as a coolant, can be replenished in flight by condensing a portion of the heat exchanger exhaust or condensing water as part of the environmental control system function or by condensing a portion of the engine exhaust. | 10-11-2012 |
20120322354 | HEAT PUMP FOR SUPPLEMENTAL HEAT - A system for providing heating and cooling to an aircraft has a single compressor for compressing and heating a fluid, a first zone and a second zone. The first zone has a first expansion valve without a condenser and a first heat exchanger removing heat from or adding heat to the first zone. The compressed fluid passes through the first zone and the first expansion valve. The second zone requires cooling and has a second expansion valve without a condenser and a second heat exchanger for removing heat from the zone. The compressed fluid passes through the second expansion valve after going through the first expansion valve and before passing through the second heat exchanger. | 12-20-2012 |
20130055724 | GAS TURBINE ENGINE AIR CYCLE SYSTEM - An air cycle system for a gas turbine engine includes a compressor, a turbine and a heat exchanger fluidly connected between the compressor and the turbine. A fluid source communicates a fluid through the heat exchanger. The heat exchanger exchanges heat between the fluid and an airflow communicated through the heat exchanger from the compressor to provide a conditioned airflow. | 03-07-2013 |
20130098585 | FREE-SURFACE LIQUID CAPTURE DEVICE FOR ROTATING MACHINERY - A free-surface liquid transfer apparatus for rotating machinery includes a stationary member. The stationary member includes a main surface configured to align to a rotating member, a landing surface arranged around the main surface configured to receive and slow a continuous film of working fluid transferred from the rotating member, an annular gap arranged around the landing surface, and a hollow torus cavity arranged proximate the annular gap configured to receive the slowed continuous film of working fluid transmitted through the annular gap. | 04-25-2013 |
20140342201 | ELECTRICAL STORAGE DEVICE THERMAL MANAGEMENT SYSTEMS - A thermal management system for a high density power source is disclosed. The system includes a housing with an interior divided into first and second compartments. The first compartment is configured and adapted to house at least one electrical battery and the second compartment defines a coolant reservoir. A fluid release member connects the first and second compartments. Upon the first compartment reaching a temperature in excess of a predetermined limit, the fluid release member releases coolant form the second compartment into the first compartment to cool the at least one battery within the first compartment. | 11-20-2014 |
20140363718 | THERMAL CONDUCTIVITY CONTROL DEVICES - A system for controlling thermal conductivity between two thermal masses is disclosed. The system includes a first conduction body in thermal contact with a heat source and a second conduction body in contact with a heat sink. A thermal expansion component operatively connects to the first conduction body and moves the body between first and second positions at a predetermined temperature. In the first position the first conduction body is spaced apart from the second conduction body, thermally isolating the heat source from the heat sink. In the second position the first conduction body thermally contacts the second conduction body, and conducts heat from the heat source, through the conduction bodies and into the heat sink. Related methods are also described. | 12-11-2014 |
