Cool bag?

[nashvillecat]

Realoem lists universal accessories something described as a "cool bag" pt no. 82299415579. See http://www.realoem.com/bmw/showparts.do?model=7031&mospid=47808&btnr=82_0308&hg=82&fg=26

t looks like a glorified heat sink to keep the Campari and brats at slightly above room temp. Or, maybe it is a portable air conditioner for the rear passengers and a parakeet. I can't recall ever seeing one "in the flesh."

That's a new trick. The only BMW in-car non-person cooling I had seen before are the coolers that were in the rear armrests of some E34s and various models of 7 series.

Had I to hazard a guess, it probably used a small pump and some heat transfer fluid to keep the walls cooler than ambient. Unless it's got a really teensy compressor in there, I can't think of how else it would work, since I don't think they had solid state active cooling in those days. (using a special transistor setup) Heck, if they added a fan on the side, it would work a lot better.

Evidently this is a new accessory for all models and, its CFC free! It looks like it would go nicely with the factory coat hanger.

It's call a Thermo-electric cooler (TEC) which uses the Peltier Effect (1834).

You could save a lot of money by going to Wal-Mart.

Or you could buy a soft-sided cooler of your choice and DIY.
