I agree, you're a well-rounded engineer capable of solving problems with simple solutions even when they are outside of your discipline. I wish you worked for me, of course, we don't allow smoking in our building.
Excellent work Rob. Delivering 1000 units a month sounds challenging enough. This thermal problem benefitted from the application of aerodynamics. And a clever cost effective design to follow. Seems as though being multi-disciplinary is an asset to many machine designs...
Brilliant engineering indeed! The problem with laminar flow cooling is that there is always a sttagnation zone covering all the fixed surfaces, and the velocity gradient rising as you move away from those surfaces. Finding the cost-effective means of getting turbulent flow was the engineering end of the solution. Good job indeed.
I took some photo's of the only unit I had.. My original Prototype which was prior to the design completion of the said thermal solution and Origami cables. I hope this illustrates the point.
Basically I prevented the air from flowing over top the PSU which had a 1/4" gap or so by blocking that with a plastic cover and created more turbulence with a front opening that also increased the linear air velocity which significantly reduces hot spot temperature rise inside the power supply (PSU). In this case form Lambda. THis prototype was built 4 weeks after a paper napkin design spec and was later finished 3 weeks later and hand delivered to AVAYA in Denver.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
