Methods and devices for cooling systems () are provided that are in fluid communication with bleed air from a jet engine compressor. The cooling systems include: a first precooler () receiving bleed air from the jet engine compressor; a heat exchanger () downstream from the first precooler (); a cooling system compressor () downstream from the first precooler (), wherein the heat exchanger () and the cooling system compressor () are in separate flow paths from the first precooler (); a cooling system precooler () downstream from the cooling system compressor (); a cooling system turbine () with variable guide vanes&#x2014;VGT&#x2014;and downstream from the cooling system precooler (); and a discharge conduit () downstream from the cooling system turbine () and the heat exchanger (). A bypass line () can also be included that bypasses the cooling system turbine ().

Jet engine cold air cooling system

An aircraft heat exchanger that exchanges heat between fluid, like air, to be warmed and a medium, like a liquid, to be cooled has a first path that encounters the fluid to be warmed and carries the medium at a first temperature. A second path carries the medium at a second temperature adjacent to the first path. An insulation gap is disposed between the first path and the second path so that heat exchange between the first and second path is minimized.

Heat exchanger insulation gap

A thermal management system comprises a first heat exchanger having an inlet and an outlet, a second heat exchanger having an inlet and an outlet, a fluid loop, a first heat pump, and a second heat pump. The fluid loop circulates a fluid, and forms a continuous path between the first and second heat exchangers. The first heat pump is connected to the fluid loop and is disposed between the outlet of the second heat exchanger and the inlet of the first heat exchanger. The second heat pump is connected to the fluid loop and is disposed between the outlet of the first heat exchanger and the inlet of the second heat exchanger.

Thermal management system with staged cooling

A thermal management system avoids problems associated with the recirculation of fuel through a fuel tank on an aircraft in a system that includes a fuel reservoir ( ), a pump ( ) for pumping fuel from the reservoir ( ) to a first heat load ( ) and then to a check valve ( ) to a junction ( ). At least one second heat load ( ), ( ), ( ) is connected to the junction ( ) and a fuel/fan air heat exchanger ( ) having a fan air flow path in heat exchange relation with a fuel flow path having a fuel discharge end ( ) connected to the junction ( ). The fan air flow path is adapted to be connected to receive compressed air from the fan ( ) of an engine ( ). A bleed air/fuel heat exchanger ( ) receives fuel from the second heat load and bleed air from the engine ( ) and is connected to deliver fuel to the engine ( ). A control valve ( ) is interposed between the second heat load and the engine ( ) for proportioning the flow of fuel to the engine ( ) and the fuel fan heat exchanger ( ) so that excess fuel is recirculated without reintroduction into the fuel reservoir ( ).

Integrated thermal management and coolant system for an aircraft

A moisture collector for collecting moisture from moisture containing air exiting from an air conditioning system in substantially a first flow direction is disclosed. The collector including a moisture collector housing defining a volume. An inlet extends into the volume for receiving the moisture containing air from the air conditioning system while substantially moving in the first flow direction. An outlet extends out of the volume for exhausting substantially moisture free air. A device for redirecting the moisture containing air is positioned within the volume and upstream of the outlet. At the device, moisture is removed from the moisture containing air for forming the substantially moisture free air. An air passageway is defined in the volume for directing the substantially moisture free air from the device for redirecting toward the outlet along with the moisture. A volume for collecting the moisture is provided. A device is positioned in the air passageway in the path of the moisture free air for directing the moisture moving with the moisture free air into the volume for collecting downstream of the outlet.

Compact water collector

An air cycle air conditioning system comprises a first air source for supplying cooling air and a second air source for supplying high temperature system air. The system further includes a device for transferring heat from the high temperature air and producing conditioned air having a temperature substantially lower than the high temperature system air. A mechanism for directing the conditioned air to the high temperature air prior to the high temperature air entering a component of the system for decreasing the temperature of the high temperature system air, prior to it contacting the system component is also provided. An air cycle air conditioning method comprises the steps of supplying cooling air and high temperature system air to a system component; transferring heat from the high temperature system air and producing conditioned air having a temperature substantially lower than the higher temperature system air; and mixing at least a portion of the conditioned air and the system air prior to its contact with the system component for decreasing the temperature of the high temperature air prior to reaching the system component.

Air cycle refrigeration and air temperature quenching system and method

An air mixer, with a water collector, is disclosed for supplying recirculated cabin air in aircraft. In the preferred embodiment: used cabin air flows over pipes of colder fresh air to cool the used air and condense out most of the moisture contained in it; the fresh air and used air are passed over opposite faces of a ring of stator vanes, thereby imparting swirls to both types of airstreams; and the streams meet at the trailing tips of the stator vanes, where they corkscrew together to throw remaining coalesced moisture against a collection trough, from where it is discharged. The airstreams can now be injected into the cabin without droplets raining down on the passengers, nor ice clogging any pipes for the fresh air, which is typically supplied at below-freezing temperature.
