Sandia Cooler

Heat exchangers are used for the transfer of heat between two or more media. The media may be separated by a solid wall so that they never mix, or they may be in direct contact. Heat exchangers may be used in HVAC systems,...

Preliminary Design of a Cryogenic Hydrogen Radiation Shield for Human Spaceflight

Human susceptibility to the harsh space radiation environment has been identified as a major hurdle for exploration beyond low-Earth orbit (LEO)....

Two-Phase Thermal Switch

There is a wide range of spacecraft thermal management applications that require variable conductance devices such as thermal switches. These switches are used to help maintain the heat source (electronics)...

Heat Pipe Solutions for LED Devices

LEDs are experiencing increasing acceptance and growth across many market segments. Part of this growth is due to new, higher-power LEDs that can be packaged in increasingly small areas. However, increased...

Composite-Matrix Regenerators for Stirling Engines

A prototype Stirling-engine regenerator containing a matrix made of carbon-fiber-based composite materials has been developed. The concept underlying this development effort is one of...
