Researchers at Stanford have designed the first lithium-ion battery that can shut down and restart on its own to prevent overheating. “The battery shuts [itself] down before overheating, then restarts immediately when the temperature cools,” reported Stanford News. The authors of the study used graphene-and-carbon-coated nanoscale spiky nickel particles embedded in a thin … [Read more...]
New “Kinetic Cooling Engine” CPU Cooler Design
Startup MIT company, CoolChip, demonstrated a new commercial prototype CPU cooler recently at CES. “They’ve partnered with Cooler Master to release a “kinectic cooling engine” that can cool a chip 50 percent more efficiently than a conventional cooler, in a form factor that’s half the size and emits much less noise,” according to Spectrum IEEE. It is true that “Sandia Labs … [Read more...]
Redesigned Heat Sinks Using 3D Printers
Plunkett Associates has successfully redesigned heat-sinks to improve convection cooling performance using Direct Metal Laser Sintering (DMLS), or 3D printing. “Each heat-sink was first produced in virtual form and simulated using Computational Fluid Dynamics (CFD) software,” reported 3Ders.org. “The top five heat-sinks were then built by 3T RPD Ltd. using DMLS and physically … [Read more...]
Protection Coatings for Coolers to be Presented at Upcoming Conference
On February 26 at the Photonics West Conference in San Francisco Rogers Corporation’s Power Electronics Solutions (PES) will be presenting a report on ACT’s vapor-deposited Applied Nanoscale Corrosion Resistant (ANCER™) coatings in partnership with Advanced Cooling Technologies. According to the company, the thin, conformal ANCER coatings “help extend the operating life of … [Read more...]
New Hybrid Adhesives Use UV Cure and Heat Cure Combination
Epoxy Technology Inc. has released a new line of UV Hybrid adhesives. The company says these adhesives allow “engineers to reach new levels of production/process improvement” and afford “greater design flexibility.” They use “a primary UV cure for tacking, followed by a secondary heat cure for completion,” according to Epoxy, “This unique combination affords engineering … [Read more...]
