Thermoelectric materials—substances that exhibit the so-called thermoelectric effect, in which a temperature difference creates an electric potential or vice versa—have been known for decades and employed in applications including power generation and refrigeration. Despite their commercial use, however, scientists have remained somewhat baffled as to why some of these … [Read more...]
Heat Pipe Assembly for Spacecraft and Hypersonic Vehicles Passes NASA Hypersonic Tests
Advanced thermal solutions provider Thermacore has announced that its heat pipe assembly recently completed testing at the NASA Ames Arc Jet Complex operating at very high temperatures in a hypersonic leading edge simulation, making it the first rigid embedded heat pipe module to operate successfully at those conditions. The demonstration confirms that the embedded heat-pipe … [Read more...]
Waste Sulfur May Improve Thermal Imaging Lenses
The discovery of a new use for waste material left over refining fossil fuels could lead to benefits for the thermal imaging industry. A University of Arizona-led international team has found that the sulfur left over from the refining process can be transformed into inexpensive, lightweight plastic lenses for infrared detection devices. "We have for the first time a polymer … [Read more...]
Small NEMA 12 Cabinet Coolers Resist Heat And Dirt
EXAIR has introduced new small NEMA 12 cabinet cooling systems to keep electrical enclosures cool while resisting heat and dirty environments that could adversely affect the internal components. Featuring a cooling capacity of up to 275 Btu/hr or 550 Btu/Hr, the new EXAIR cabinet coolers circulate 20°F (-7°C) air throughout the enclosure to prevent high temperature … [Read more...]
Thermal Material Provides Both Compressibility and Conformability with Phase-Change Ability
AI Technology, Inc. has released COOL-PAD™ CPR7154, a thermal interface material that dispenses like a thermal pad but exhibits characteristics like that of a grease or gel when device temperatures increase to above 45°C. Ideal for use in LEDs, gaming consoles, laptops and desktop computers, COOL-PAD™ CPR7154 is optimized to accommodate large areas with different heights and … [Read more...]
