Through several successful and unsuccessful projects, I have determined without any uncertainty that any enclosure must provide an unrestricted flow of cooler, fresher outside air to the AVR and alternator core - period!
This is a critical issue. Simple solutions have been to remove the AVR and simply extend the wiring harness so it is "outside the box". Unfortunately, this does nothing to boost the air flow across the innards of the alternator.
While it may look crude, the coffee can and metal duct tape approach with a conventional 12 Volt or 120 VAC "muffin fan" in the end of the coffee can has proven to work well for additional air flow. The muffin fans are normally square corner, which can be cut off so the fan fits inside the coffee can.
The first photo below shows the open end of an alternator and the AVR sitting in front.
Photo #2 is a typical AVR
Number 3 shows how the simple coffee can cooler is assembled and attached.
The last photo is a surplus ROUND fan that is perfect for the alternator - finding the right size takes a little searching on the surplus web sites.
Lastly, and since my photo library is open so I can grab images easily, one must respect the design air flow of the OEM generator. The photos below show that airflow pattern. Do NOTHING to alter this air flow pattern - if possible augment it with fans to assure adequate air movement.
