DSI Ventures, Inc., a developer of biodegradable lubricants and electrical insulating products, has announced the expansion of its OptiCool line of dielectric heat transfer fluids. Introduced in 2001, OptiCool fluids are made from synthetic paraffin hydrocarbons, and are used to cool and insulate computer services, high-torque DC motors, power electronics and avionics. “We … [Read more...]
Heat Exchanger Research Could Lead to Better Liquid Cooling in Aerospace, Automotive, Defense Applications
A New Mexico State University assistant professor is investigating methods of increasing heat exchanger efficiency that could enable space missions to remain in orbit for longer periods of time and lead to better automotive, defense, data center and power generation thermal management systems. “The problem we are addressing is how to extend NASA space missions,” Krishna Kota, … [Read more...]
IEC 62610-4 ed1.0: Cooling Performance Tests for Water-Supplied Heat Exchangers in Electronic Cabinets
From the International Electrotechnical Commission Webstore: “IEC 62610-4:2013 specifies the test setup and test parameters for water-supplied heat exchangers within single electronic cabinet configurations. The tests are focused on cabinets for the installation of high power dissipation electronic equipment. The cabinets concerned are from the IEC 60297 (19 in) and IEC 60917 … [Read more...]
NASA Astronaut Releases Video on Helmet Leak
Several weeks after NASA aborted a spacewalk outside the International Space Station following a report of a water leak inside Italian astronaut Luca Parmitano’s helmet, Parmitano’s spacewalk partner has released a two-part video explaining the origin of the leak. The July 16 spacewalk was aborted approximately an hour-and-a-half into what was to be a six-hour spacewalk to … [Read more...]
High Temperature Capacitors Could Remove Need for EV Cooling Systems
A new lead-free, high temperature ceramic capacitor developed by scientists at the National Physical Laboratory (NPL), UK could improve the efficiency and reliability of electric and hybrid vehicles by enabling the removal of heavy complex cooling systems. “Electric vehicle operating temperatures can go up to 140°C [almost double the temperature conventional capacitors can … [Read more...]
