Disclosed herein are cooling systems, methods of making cooling systems, and methods of cooling using cooling systems. A cooling system includes a compression container with a coolant that includes a fluid. A valve is arranged on the compression container through which the coolant is released from the compression container. The cooling system further includes a component positioned to receive droplets of the coolant. The component has a surface with a three-dimensional topography that includes a plurality of pillars and a plurality of trenches. The component is an electronic component or a photoelectronic component.

Electronic cooling systems

An apparatus includes a chamber, a first heat exchanger, an adapter, and a second heat exchanger. The first heat exchanger includes a cold finger positioned within the chamber. The second heat exchanger is positioned around an adapter and within the chamber. The second heat exchanger is a counter flow heat exchanger to precool refrigerant entering a Joule-Thomson valve. The adapter is positioned between the cold finger and the second heat exchanger. The adapter transfers heat from a thermal load to both the cold finger and the refrigerant emitted from the Joule-Thomson valve.

Joule Thomson aided Stirling cycle cooler

An open-loop thermal control system and method for components that generate heat includes a reservoir for containing a pressurized working fluid, a first heat exchanger in thermal communication with the working fluid, a Joule-Thomson expansion valve in fluid communication with the reservoir, and a second heat exchanger in fluid communication with the valve. The first heat exchanger is configured to transfer heat from the components to the fluid in the reservoir. The valve is configured to expand the working fluid into a two-phase fluid having a primary use of cooling. The second heat exchanger is configured to receive heat from the components and receive the two-phase fluid. The second heat exchanger provides a single-phase working fluid for at least one secondary use before the working fluid is expelled from the thermal control system.

Multifunctional aerodynamic, propulsion, and thermal control system

A Dewar apparatus includes a focal plane array (FPA) component coupled to an FPA carrier, and a cold bridge coupled to the FPA carrier. A cold shield is aligned with the optical axis and coupled to the cold bridge (e.g., via a direct-metal bond), and at least one cryostat enclosure is similarly coupled to the cold bridge such that it has an axis that is noncollinear with the optical axis.

Methods and apparatus for Dewar and cold shield assemblies

A diaphragm pressure regulator comprising a housing having first and second sections. The first section 1a has a cavity or vacuum space, and a wave spring is disposed in the vacuum space, a load distributor is disposed adjacent to the wave spring, and a diaphragm seals the cavity and secures the wave spring and load distributor in the cavity. The second section of the housing comprises a movable and sealable vent stem that moves in response to movement of the diaphragm, and a vent opening for venting the interior of the second section of the housing to external pressure in response to motion of the diaphragm. The diaphragm pressure regulator may be preferentially used in an upper atmospheric system that needs to maintain a specified pressure, but requires venting capabilities. Such systems include missile systems that fly into the upper atmosphere.
