This style needs to be wired to the fridge interior light (easy to do) and circulates air over the cooling fins to help prevent ice building up on the fins.
When placed on a bottom shelf this one helps circulate the air inside the fridge.
Then there's one that passes air thru the plenum on the back of the fridge. If you type 'fridge fan' in the search box above you'll find threads on this.
