That is basically a CPU cooler out of a PC mother board or a larger version of the old 12volt 6 pack car fridge
If you swap the + and - wires around it will heat instead of cool
I was thinking about this before If I did it again Id use the two hinges but have a single rod attached to the TV so I could rotate the TV 180 degrees so i could lay i a V birth and also use the same TV

Fridge add on
so you could cook a slow roast or soup and when it cools swap the wires over and refrigerated it

or eat some and then refrigerated it
