Abstract:Future Lunar Landers and Rovers will require variable thermal links that can reject heat during daytime, and passively shut-off during lunar night. During the long lunar day, the thermal management system must remove the waste heat from the electronics and batteries keep them within the acceptable… more
Abstract:While continuously increasing in complexity, the payloads of terrestrial high altitude balloons need a thermal management system to reject their waste heat and to maintain a stable temperature as the air (sink) temperature swings from as cold as -90<SUP>o</SUP>C to as hot as… more
Abstract:Grooved aluminum/ammonia Constant Conductance Heat Pipes (CCHPs) are the standard for thermal control in zero-gravity. Unfortunately, they are limited in terms of their heat flux capability, approximately 5W/cm2. Incident heat flux for laser diode applications is on the order of 5-10W/cm2,… more
Abstract:The VASIMR propulsion system uses a high temperature Loop Heat Pipe (LHP) radiator to reject heat from the helicon section. The current baseline radiator uses titanium/water LHPs, however, deployable radiator and trace heating features are required to keep the water in the condenser from freezing… more
Abstract:This Phase I project aims to increase the reliability of radio frequency (RF) devices used in accelerator facilities by reducing/eliminating corrosion and erosion produced from the high purity de-ionized water cooling systems. Although metal interconnects are the required for electrical and thermal… more
Abstract:In 2005, commercial and residential Heating, Ventilation, and Air Conditioning (HVAC) systems represented 518 billion kWh of energy consumption in the United States, which amounts to 8% of the total energy produced that year. In addition, producing this power resulted in the release of 465 MMTCO2e… more
Abstract:It is well established that prolonged operation at high junction temperatures reduces the lifetime of LEDs, significantly undermining one of the main benefits of LED lighting systems. Despite advances in LED device technology, a significant fraction of the electrical energy input is wasted as heat.… more
