Recently, Moscow Institute of Physics and Technology researchers Dmitry Fedyanin and Andrey Vyshnevyy have solved and “demonstrated how to efficiently cool optoelectronic microprocessors” by using industry-standard heat sinks, according to Phys.org. Optoelectronic chips’ active plasmonic components tend to overheat from high-speed data transfer, but by switching electrons with … [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...]
New Cooler Can Advance Heat Exchanger Technology
Recently, researchers at the Energy Department’s Sandia National Laboratories have developed an innovative new air-cooling technology called the Sandia Cooler. “The Sandia Cooler combines a fan and a finned metal heat sink into a single element called a heat-sink-impeller in which the fins of the heat sink rotate, improving heat transfer by a factor of ten,” reports … [Read more...]
Heat Sink Optimization through Use of Pin Fins
In a recent blog post, Robert Smith discusses heat sink optimization through the use of pin fins. “Local heat transfer coefficients are highest when the air first begins to form a boundary layer. The benefit to lots of pins is that you force the boundary layers to break away often and re-create on the next pin,” Smith said. The heat sink forms a 3D mesh of pins that cross … [Read more...]
Thermal Invisibility Cloak Improves Heat Distribution in Electronics
A team of researchers from the Nanyang Technological University (NTU) in Singapore has developed a thermal invisibility cloak that would improve heat distribution in electronic devices by redirecting incoming heat. The cloaks are capable of guiding heat around a hidden object, thus resulting in complete thermal invisibility. “Based on carefully engineered metamaterials – … [Read more...]
