Refrigerator cold air catcher

Possibly the OP is on to something?

Home grade refrigerators have been manufactured for decades without any type of air dam.
Maybe it's time for an 'energy saving change?' I wonder how much energy would be saved if all refrigerators had an air dam?

I'm sure the Wright brothers were told their contraption would never work.

And maybe opnspaces is right. Any energy saved by the dam would be canceled by the vortex created when the door is opened.

Remember those TV commercials with a standup and a chest freezer full of ping pong balls? When they open the standup freezer all the balls fall out signifying all the cold falling out of the open door?

My thought that is that yes the original cold may fall out of the open refrigerator. But once you close the door all the items in the refrigerator sublimate some of their cold into the open air spaces and cool the interior.

As far as the cardboard dam I'm thinking it can't hurt. But it seems that the vortex created when opening the door will probably just swirl the cold out regardless of the dam.

Not really sure what you're trying to accomplish,
#1. that cardboard, or whatever it is at the bottom where the crisper drawers should be isn't accomplishing anything as far as keeping the cold in.
#2. that little white clip with the white "cord" going to is is the thermistor , I've never seen one in that position, usually it is positioned on the far right fin, sliding it up adjust the temperature colder.
