Ultra-thin Cooling Jets for Next-gen Electronics
Just when you think technology has hit a wall in its ability to scale downward in size, another breakthrough surfaces, and our cell phones and tablets shrink yet again. But this time, it's not because of Moore's Law. Instead, this innovation comes in the form of ultra-thin cooling jets, recently unveiled by GE Global Research.
According to GE researchers, the technology, called Dual Piezoelectric Cooling Jets (DCJ), can dissipate heat at ten times the rate of natural air circulation, and take up significantly less space than traditional cooling fans.
According to Peter de Bock, lead electronics engineer at GE Global Research, DCJ is now the optimal cooling solution for ultra-thin consumer electronics. “It's very low power, very simple, and a unique solution for very thin laptops, ultrabooks and the next generation of more powerful tablets.”
But how does it work?
The DCJs feature two ceramic plates that, when supplied with electricity, expand and contract, creating high-velocity airflow. Nearby heated components can then rapidly dissipate heat, just as they would with traditional fans.
This technology is significant, however, because the ceramic plates measure just one millimeter tall, while the entire cooling assembly is a mere 4 millimeters tall – 50 percent smaller than current cooling units.
On top of that, the DCJ uses 50 percent less power than fans, is nearly silent and uses no rotating parts that require maintenance and are prone to breakage.
“[The] DCJ technology not only frees up precious space for system designers, but it consumes significantly less power, allowing as much as 30 minutes of extra battery life,” says Chris Giovanniello, vice president of microelectronics and thermal business development at GE Licensing.
Not only could this technology mean slimmer personal electronics, it also may enable longer battery life and quieter machines, which, thanks to their simplicity, will cost less.
Currently, GE produces the prototypes at a rate of 20 per month. But the technology has now been licensed to Japan's Fujikura LTD for manufacturing, with the high-volume production slated for 2013. It could be inside our cell phones and tablets as early as 2014.
The ability to control fluid streams at microscale is of great importance in many domains such as biological processing, guiding chemical reactions, and creating structured materials. Recently, it has been discovered that placing pillars of different dimensions, and at different offsets, allows fluid transformations to “sculpt” fluid streams. Read more...
So far, the story surrounding the industrial Internet has been centered around GE, and their plans to infuse their factories with thousands of sensors that will bring big data to manufacturing. But after record-breaking floods from Hurricane Sandy took their toll on New York and New Jersey, environmental and civil engineers have found a new application for the Internet-connected sensor system.

As the cloud becomes an increasingly attractive option for manufacturers with big needs in IT, scalable options such as outsourced data centers have become a must-have for many companies. But General Motors has taken a step in the opposite direction when its $130 million datacenter went online Monday in the suburb of Warren, Michigan. Read more...

While advanced carbon-fiber composites have been used in the recent years, researchers are searching for materials that are even stronger and lighter. Composites made with carbon fibers coated with carbon nanotubes are being considered because they can be hundreds of times stronger than steel and only one-sixth the weight. Read more...

NASA has awarded a $125,000 grant for a project intended to 3D print food for astronauts in space. The printer will mix together basic nutrients such as oil and protein powder to create the food. It will also allow the user to input their sex, age, and weight so that it can make the food based on the individual's own nutritional needs. Read more...

This week, Airbus towed its newest airliner, the A350 XWB, out of its hangar and is poised to roll it into the spotlight of the upcoming Paris Air Show. The A350 XWB has been designed with the goal of surpassing the 787 in fuel efficiency and comfort, and has forgone metal for composite materials to make it happen. Read more...
03/20/2013 | SAS | This white paper examines how an enterprise-wide quality platform can turn existing data into substantial and sustainable revenue growth and cost savings for global manufacturers. The paper is based on the findings of the IW/SAS Enterprise Quality Survey completed by more than 400 manufacturing executives. The objectives of the survey were to determine concerns about quality among manufacturers; investigate the tools used to measure quality; and examine how using enterprise-wide analysis on quality data improves performance.
