This is what a typical extruded fin heatsink looks like. It’s made of metal and sits on top of IC packages that themselves are soldered to a PCB. It cools those packages by providing an increased air apparent surface area with which to pass on the heat that has been conducted up through it. It’s shape (topology) is in most ways set by the manufacturing process used to create it. In this case squeezing molten aluminum through a die with that shape as the profile. Similar constraints exist for other manufacturing processes, be it milling, casting, brazing etc. 3D printing removes many of these constraints and, as the technology matures, I believe all of them will be addressed. So, with a process that can print any 3D shape, how should design tools adapt to such an opportunity?
A manufacturer of road repair equipment had a problem: his infrared heater used to warm pot hole patches and surrounding road surface was not putting out enough heat. He had two solutions, he could either enlarge the infrared burners used as the heat source (using more propane at an added cost) or increase the reflectivity in the shields behind the burners to direct more heat towards the pavement. By applying LO/MIT radiant barrier coating to the shields, he solved his problem with very little additional cost (pennies per square foot) and increased the efficiency of his units because the BTU output of the heaters was now directed at the target road patches.
Whether you need to enhance or block infrared heat flows, our Lo/Mit low emissivity paint products perform over wide temperature ranges and operating conditions from the inside of engine compartments and roofs of hockey arenas to the coating of steam boilers and rocket ships. They can be easily applied to any geometric shape and on most substrates to alleviate radiant heat transfer problems at low cost and extremely low weight. Give us a call at: 609-883-7700 or visit our website at: http://www.solec.org/index.php/lomit-radiant-barrier-coating/lomit-technical-specifications/ to learn more about our low cost, single component Lo/Mit-I, II, and II MAX products.
OOF is designed to help materials scientists calculate macroscopic properties from images of real or simulated microstructures. It reads an image, assigns material properties to features in the image, and conducts virtual experiments to determine the macroscopic properties of the microstructure.
05_Sci_Matter and Materials_002_Investigating heat conduction_Video Learner Video Heat energy can be transferred from one material to another. Some materials transfer heat (conductors) more easily than others (insulators).
Focused on the solution of heat transfer problems in nanomachines, this practical resource integrates traditional knowledge with cutting-edge theory to provide a solid foundation and working technical skills.
Distance education has been undergoing incremental change over the past decade or so since the advent of the commercial Internet and the World Wide Web. However, we are currently on the cusp of advances that will facilitate experiential learning at a distance, reduce the cost of distance education production, expand access to education, and closely integrate formal education into the fabric of everyday life. Following a review of distance education technology past and present, this paper presents the evolving technologies that will facilitate the most important advances in the field and reviews their early applications.
Green approach to inorganic nanostructures: CuCl nanoplatelets (see picture) were synthesized from mixtures of a Cu-containing ionic liquid crystal and 6-O-palmitoyl ascorbic acid. The particle size, thickness, and connectivity can be adjusted through varying the reaction temperature. The copper-containing precursor acts as both the template and the copper source. The ligand is not consumed in the precipitation and can be reused.
Anyone who's dropped a cellphone in the bath knows that water and microelectronics don't usually mix well. But at IBM's Swiss lab in Zurich, marrying the two is becoming almost commonplace: microprocessors with water coursing through microchannels carved deep inside them are already crunching data in SuperMUC, an IBM supercomputer - with the heat that the water carries away used to warm nearby buildings.
This lattice uses a new microfluidic printhead that is able to seamlessly switch between printing two different viscoelastic inks. The structure, which was printed with red and transparent inks, showcases the sharp transitions possible with the new nozzle.
Curious about just how far they could take the company’s additive manufacturing technology, engineers at GE Aviation’s Additive Development Center in Cincinnati successfully created a simple jet engine, made entirely from 3D printed parts, that was able to rev up to 33,000 RPM.
