I'm still thinking about an automatic air diverter. I wonder if an something with Bimetal could work, (passive only, no solenoid or motor) . The hotter it gets the more it would bend and therefore divert the air to another outlet.

Have to do the math.

Haven't tried it but I think it would work. There was some discussion on here a few months ago about using bimetal-actuated vents to cool overheated collectors. What you are proposing is essentially the same thing. Don't know how it came out, though.

You might be able to modify something like this: http://www.amazon.com/Witten-Automatic-306MGR-Foundation-Ventilator/dp/B000DZF2X2/ref=pd_sim_sbs_hi_3?ie=UTF8&refRID=1P3N7MCH0B10FH23DBKC

I've got to believe there is a spring-loaded (generic term) damper system. The old heat switch switches in furnaces use to be twisted metal in a spiral.

It rotates back-n-forth to turn on-off the fan. This is long before the thermal snap switches today. I'm betting they used the same type device for dutwork dampers.

Have you talked to a local furnace repair company in your area? I'm betting an old-timer furnace guy knows what they are & may have one in a warehouse.

I agree with the Bimetal vent in the link. I think it would work.

There seem to be lots of "flue" and "duct" dampers out there. Many of them are electric, and could be controlled remotely with with a thermostat. Depending on the application, might be something to consider.
