Vapor-compression cooling can be found in virtually any home, such as in air conditioners that remove heat from our homes and in refrigerators that store our food. The history of vapor-compression goes back to 1805 where Oliver Evans, an American inventor, described a closed vapor-compression refrigeration cycle for producing ice. The first working vapor-compression … [Read more...]
Advanced Cooling for Power Electronics
Power electronics devices such as MOSFETs, GTOs, IGBTs, IGCTs etc. are now widely used to efficiently deliver electrical power in home electronics, industrial drives, telecommunication, transport, electric grid and numerous other applications. This paper discusses cooling technologies that have evolved in step to remove increasing levels of heat dissipation and manage junction … [Read more...]
New Line of Dielectric Coolants Launched
Engineered Fluids announces the commercial release of its CoolFluids line of high performance dielectric cooling fluids. Designed specifically for single phase, direct immersion cooling of electrical devices, CoolFluids are biodegradable, non-toxic, synthetic dielectric coolants with more than 1800x the cooling capacity of air. In addition, CoolFluids have an extremely … [Read more...]
Simulate electronics cooling strategies to design products more effectively
Sponsored by ANSYS Determine the Thermal Signature of an Electronic System As electronic devices become smaller, denser and faster, the structural and thermal integrity of their electronic packages and printed circuit boards (PCBs) becomes more critical. Heat affects the performance and reliability of integrated circuits (ICs) and may cause failure. Keep things running … [Read more...]
Someday Humans Will “See” The Heat!
Many biological creatures are enabled with the ability to “see” the heat – reptiles, for example, effectively use this ability to detect the size of the heat-emitting object and its range. Other biological entities, including mammals, are enabled with the ability to perceive heat by a process known as Thermoception or Thermoreception. As humans, we are capable of sensing … [Read more...]
