A well-known method of making heat sinks for electronic devices is a process called sintering, in which powdered metal is formed into a desired shape and then heated in a vacuum to bind the particles together. In a recent experiment, students at MIT led by Kripa Varanasi, d’Arbeloff Assistant Professor of Mechanical Engineering, tried sintering copper particles in air and … [Read more...]
Solar-Powered Lasers Use Heat Sink for Cooling
A researcher in Uzbekistan has proposed a plan for solar-powered lasers using small parabolic mirrors about 3 feet in diameter, combined with new two-layer ceramic disks to produce laser light. When sunlight hits the ceramic material, it excites the electrons and causes them to emit laser light of a specific wavelength. To control the heat, the ceramic disk would be mounted … [Read more...]
Optimal Thermal Management Performance Solution
Newark has established an exclusive stocking agreement for Wakefield Solutions’ new LED heat sink extrusions. Wakefield and Bridgelux engineering teams worked together at Newark’s behest to design an optimal heat sink extrusion line which is compatible with all Bridgelux LEDs. Wakefield’s new heat sink extrusions save engineers the considerable time it can take to match the … [Read more...]
New Heat Sink Series with Push Pin Mounting System
Advanced Thermal Solutions, Inc.’s new series of its maxiFLOW™ heat sinks now include an integral push pin mounting system for fast, safe attachment of the heat sinks onto BGAs and other hot components Each heat sink comes with a pair of durable push pins in a choice of plastic or brass. The pins push mount easily and securely into 3.00 mm holes in the PCB. The holes are … [Read more...]
New Air-Cooling Technology Reduces Energy Use
Sandia National Laboratories has developed a proprietary air-cooling invention, the “Sandia Cooler,” also known as the “Air Bearing Heat Exchanger.” The Sandia Cooler technology, which is patent-pending, will significantly reduce the energy needed to cool the processor chips in data centers and large-scale computing environments. In a conventional CPU cooler, the heat transfer … [Read more...]
