flyback cooling

[DaveWM]

interesting I ran it with the back of the cage off for nearly 1 hr and it was just warm. Oh well maybe that is the answer for now. I will try it again and see how it goes.

[DaveWM]

perhaps it just needs some natural convective cooling a good sized opening on the bottom and the top right over the shunt with some spaced off caps I just hate the idea of cutting up the cage.

Duh make one, I have some scrap metal and its a very simple part to make.

[DaveWM]

a quick shot on the fly after about 30min 125 was the hottest spot, the shunt was about 310f

[DaveWM]

for you fluid dynamics types, I assume a smaller opening on the bottom near the base and a larger opening on the top would work best? I am thinking of about a 2" round opening near the base and a 3" opening on the top.

after 1 hr it was at 140f, too hot for me, so I placed a 3" 12v fan on a 9v battery right at the base, within minutes it was down to 100f so looks like I will stick with forced air cooling. I have some other sets that have much harder to come by flys that will also get the treatment.

5 more min and its down to the low 90's wow...

will be interesting to see it spike when I turn off the set (and remove the power from the fan).
