WHAT KIND OF HEATSINKS ARE PEOPLE USING FOR THE 6215h SCANNERS?
I calculated 0.15 C/W is needed with a max Junction of 50C. So starting at 32C that only gives you 18C rise. Since they do max worst case 120W thats 18C/120W=0.15C/W. The Junction Case C/W is 1C/W. So adding it up, you get a neagtive C/W meaning you need active cooling. This is obviously not what is being done so I'd like to know what you are doing. Also anyone know the ratings and max junction temp for the big boy scanner amps? Guess I can look up the driver trans and get the curves. I used 32C as a worst case, that is only 90F so on a warm day that might not even be worst case inside the projector.
Thanks,
