Two new studies performed at the U.S. Department of Energy’s Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films. The unusually attractive thermal properties of diamond thin films have led scientists to suggest using this material as a heat sink that could be integrated … [Read more...]

Enhancement of Microchannel Cooling with Oblique Technology
Microchannel cooling has emerged as an effective method to enhance cooling for electronics devices [1]. However, the problem of boundary layer development, as liquid coolant travels downstream, persists in conventional microchannel heatsinks. Consequently, convective heat transfer performance of a heat sink deteriorates in the axial direction, resulting in elevated maximum … [Read more...]
Apple to Recreate Ionic Wind Generator Cooling System
The U.S. Patent & Trademark Office has published a patent application that reveals Apple’s intent to reinvent the ionic wind generator. The traditional ionic wind generator design is only effective at cooling limited areas of an electronic device and distributes air throughout the device evenly, without thought to what portions of the device are in use. According to the … [Read more...]
600-W DC-DC Converter with Integrated Heat Sink
CUI Inc is adding a 600 W device to the company’s line of rugged chassis mount DC-DC converters. The VFK600 series measures 7.8 x 5.0 x 1.5 inch and includes an integrated heat sink for improved thermal performance. The aluminum heat sink allows the unit to operate at higher temperatures with a minimal amount of air flow. The VFK600 is offered in five different regulated output … [Read more...]
