I have been working with telecom equipment design for 13 years
we never seem or newer did anything like this :-)
so that is why i think this design is worth sharing with you

by the way : you see many other good things in this video
impressive thermal design, clearly worth getting a few ideas from
for your own high power thermal challenged projects.
