Best way to cool off my generator
I have a portable Yamaha 6600.
I put it in a small 6x5 all metal sears shed.
The intake fan faces the open door and the exhaust is at 90 degrees to that - I cut two holes at 4"x 8" in the wall where the exhaust faces - the end of the muffler is about 2.5 feet from that wall. Put another 4" x 8" hole in another wall and covered the holes with cheap vent covers from home depot.
The with this set up, the generator runs fine for 4 hours in the shade 70deg f. Seems all fine. Of course, it is still quite hot inside the shed when it is running.
If I were to add an electric fan of some kind to aid cooling, would it be better to 1) focus on bringing in fresh air to the shed, or 2) focus on expelling hot air, from the shed?
