Payam Bozorgi and George Fleischman PiMEMS, Inc. Introduction As electronic system technology advances with continual increases in requirements leading to greater demand for higher power consumption, there have been growing challenges related to the design of thermal engineering and heat rejection technologies. The need for performance inevitably leads to operation of most … [Read more...]
Waterproof Tablet Computer Features Cooling Fan
Electronics manufacturer Fujitsu has released a unique new tablet computer capable of operating underwater while using a cooling fan to pump heat away from sensitive internal circuitry. The Arrows Tab QH77/M is 2-in-1 computer that can be used both as a clamshell notebook computer and as a tablet computer when the display unit is detached. The casing houses an Intel Core … [Read more...]
Thermal Connectors Improve PCB Assembly Heat Dissipation
TEM Products Inc., a manufacturer of mechanical components for electro-mechanical assembly, has released its new patent-pending PowerPeg thermal connectors. Designed for attachment to an external dissipater, the new PowerPeg thermal connectors offer significantly improved thermal conductivity compared to traditional PCB heat spreading methods by allowing heat to dissipate more … [Read more...]
Heat Pipe Integration Strategies for LED Applications
Dr. Richard Bonner, Anqi (Angie) Fan, Daniel Pounds and Dr. Ehsan Yakhshi-Tafti; Advanced Cooling Technologies, Inc. INTRODUCTION In light-emitting diodes (LEDs), 70 percent to 80 percent of the applied electrical power is converted to waste heat. If this thermal energy is not properly dissipated, the resulting high operating temperatures lead to reduced brightness, shift … [Read more...]
NASA Selects Proposals for Future Spacecraft Thermal Control Systems
NASA has selected eight proposals to develop advanced thermal control system technologies for future spacecraft as part of its Game Changing Development Program (GCD). The program was created to investigate novel ideals and approaches to protect spacecraft and the astronauts within while enabling them to remain in space for longer periods of time. The selected proposals will … [Read more...]
