Although the short article invites to see this matters in more detail, a little more info would be appreciated...
Like: Comparing between std. aluminum vs. copper enclosures, can we use thicker aluminum wall enclosures, or using a copper layer or sheet under the aluminum box acomplish a better result? Then, how thick?... Are there any thumb rules regarding ventilation hole sizes/pitch and area, size of the perforated section? Location of perforated areas? and so on. Amclaussen.
This is a new concept for me and I can't help think about the wider implication of extending the principles to portable items and weatherproof vehicles.
In aircraft and outdoor portable units a small bore honeycomb would be vulnerable to water ingress due to capillary action. Exhaust blown air would help remove damp and condensation moisture but any air intake would be vulnerable. There would also be the issue of corrosion in residual trapped water in untreated copper or aluminum honeycomb. This could set some minimum diameter guideline.
The other out-door issue common to aircraft owners, is the minimum diameter of openings that resist the entry of insects. At certain time of the year insects find tubular openings that they can enter. They make silky nests for their larvae to grow in and can obstruct critical airflow. The maximum diameter seems to be about 0.125", which must be too small for a wasp's whiskers and head.
In common households, and maybe some industrial environments, there is the problem of dust accumulation. Think of the PC CPU cooling fins that get clogged with dust (and fine cat hair if you are a pet lover). Again with input airflow, smaller orifices attract more significant obstruction over time.
So there seems to be some mechanical Max/Min guidelines to consider in a non-sterile existence.
I wonder what has been the experience of the Laser printer manufacturers with their honeycomb blocks. This maybe synthetic, thermally and electrically non-conductive material though. Would plated plastic work?
Almost everything the military and NASA designs is in a metal enclosure afterward. It is fairly common practice to do so, I have found. I place a lot of my more sensitive projects inside a metal box routinely. So often the 60hz at the wall has been an issue with my testing, it was a necessity after.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
