flyback cooling

interesting reading. looks like adding forced air cooling IF the flyback were to catch fire would just create a blow torch out of it

I still like the idea of the cooling air flow, but will def look into the late model shunt.

after reading up on that patent, I decided to try another experiment. this time I have some thick cardboard slid in between the shunt and the fly. I had noticed in the past that the top part of the fly was the hottest, which also happens to be closest to the shunt. Perhaps radiant heating is in play, so will see if this helps. The patent shows separation between the shunt and its own cooling slots away from the fly, keeping the fly in a sealed fire proof box.

Adding combustable material into an area with potential for a high voltage RF arc is a bad idea. It can start a bonfire in a heartbeat.

Finally, a good use for all of those asbestos heat shields that people pull out of old radios and throw away

A shield redirects heat, but doesn't make it go away. Unless it directs heat out a ventilation opening, I wonder if it would make a significant difference inside a sealed box, once the system reaches full operating temperature.
