[sdiy] Power supply enclosure - heat buidup question.

[Harry Bissell Jr]

I use a 10" x 6" x 4" extruded aluminum box... with
  a +/-15V 0.8A supply bolted to one end panel. Its Aluminum...
  so the heat transfer will be better. If you maximuze the contact
  area and maybe add heatsink compound (I did NOT)... It
  would probably work OK ...
  
  ... unless ambient temps are very high (Stage ? Outdoor summer ??)
  or you leave it on for many hours.
  
  Check the electrolytic capacitor temperature  rating (and life extimates)
  
  If its (say) 2000 Hrs ar 85C, you can double that every 10C less. Its a long
  time, I'll bet :^P

  Ive got one of those ex military amo cans here,   which would fit nicely.  Im thinking i could punch some XLRs into the top,   and an IEC into the side, and itlld make a nice setup for my modular (which is   housed in skb popup cases, so no safe psu mounting point)
   
  Thatlld all work out nicely, but, im pretty   concerned about heat buildup.  The can is all metal, so i could *try* and   mate as much of the power-one's body to the can as i can, thereby using the can   as a heatsink, but its not exactly flat and smooth inside.
   
  I really dont want to add *another* fan to my   enviroment.  I could just drill sets of holes about the can, i guess, but   theyd have to be less then finger size...
   
  Maybee i should just try it out, and see what   happens, but am i wasting my time trying?
   
  Cheers, Julian
