摘要： A hypersonic aircraft includes one or more leading edge assemblies that are designed to manage thermal loads experienced at the leading edges during high speed or hypersonic operation. Specifically, the leading edge assemblies may include an outer wall tapered to a leading edge or stagnation point. The outer wall may define a vapor chamber and a capillary structure within the vapor chamber for circulating a working fluid in either liquid or vapor form to cool the leading edge. In addition, a thermal enhancement feature can enhance a heat transfer from the outer wall at the leading edge to the outer wall within the condenser section of the vapor chamber.

摘要： A hypersonic aircraft includes one or more leading edge assemblies that are designed to cool the leading edge of certain portions of the hypersonic aircraft that are exposed to high thermal loads, such as extremely high temperatures and/or thermal gradients. Specifically, the leading edge assemblies may include an outer wall tapered to a leading edge or stagnation point. A coolant supply provides a flow of cooling fluid to a porous tip that is joined to the forward end of the outer wall and defines variable porosity and/or internal barriers to direct a flow of cooling fluid to the regions of the leading edge experiencing the highest thermal loading.

摘要： A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.

摘要： A cooling assembly includes walls extending around and defining an enclosed vapor chamber that holds a working fluid. An interior porous wick structure is disposed inside the chamber and lines interior surfaces of the walls. The wick structure includes pores that hold a liquid phase of the working fluid. The cooling assembly also includes an exterior porous wick structure lining exterior surfaces of the walls outside of the vapor chamber. The exterior wick structure includes pores that hold a liquid phase of a cooling fluid outside the vapor chamber. The interior wick structure holds the liquid working fluid until heat from an external heat source vaporizes the working fluid inside the vapor chamber. The exterior wick structure holds the liquid fluid outside the vapor chamber until heat from inside the vapor chamber vaporizes the liquid cooling fluid in the exterior wick structure for transferring heat away from the heat source.

摘要： A system and method are provided for passively cooling an inverter subsystem within an enclosure. The method and system absorb heat generated by an inverter subsystem within an enclosure through a first heat spreader. The first heat spreader is thermally coupled to in the inverter subsystem and a first interior surface of the enclosure. The system and method transfer a portion of the heat from the first heat spreader to a second heat spreader through a plurality of heat pipes. The plurality of heat pipes are thermally coupled to the first heat spreader and the second heat spreader. The system and method further thermally couple the second heat spreader to a second interior surface of the enclosure.

摘要： A fluid sensor cable assembly and method uses one or more conductive bodies extending along an elongated core body for conducting a heating current to heat the cable assembly. The one or more conductive bodies also are configured to conduct an interrogation signal and to conduct reflections of the interrogation signal. One or more optical fibers extend along the length of the core body and include temperature sensitive elements at different locations along the length of the core body. The temperature sensitive elements measure heat flux out of the cable assembly at the different locations subsequent to heating the cable assembly and communicate the heat flux to a computer acquisition system.

Specifically, the leading edge assemblies may include an outer wall tapered to a leading edge or stagnation point. The outer wall may define a vapor chamber and a capillary structure within the vapor chamber for circulating a working fluid in either liquid or vapor form to cool the leading edge. In addition, a dual-modal cooling structure can enhance heat transfer from the outer wall at the leading edge to the outer wall within the condenser section of the vapor chamber.
