Bruno/Lencodrive cooling between rounds?

I have come to the conclusion that there is no easy/cheap way to cool the converter in a Powerglide. Do either the Bruno or Lenco converter units have a provision to circulate cool fluid through the converter between rounds?

With my Lencodrive , we put a shopvac hose in the bellhousing and the hose is hooked to the exhaust side of the vac so it blows air on the converter. the magnesium case of the lenco will actually dissipate heat faster than the aluminum glide case.

 

I used a shopvac hose attached to the largest leaf blower sears had and put the inlet of the leaf blower down in a bucket of ice to cool the air. Seemed to work ok. I put the air in the starter hole
