fan placement

[egh33]

I have read in my MH book that you should put a fan in the refrigerator to help circulate the cooling. I have placed a battery fan in there before, but as it gets cold the fan stops as the battery goes dead real fast. I got a 12 volt fan to place in there but I am not sure of the correct placement of the fan. Should it blow towards the fins, or away from the fins, or maybe on a lower shelf. Any one know where the best place for it?
I have it wired so it can run all the time the refrigerator is on.
Thanks

I've used a 2-D cell battery fan for years without the problem you describe.

I've found placement in the lower rear shelf blowing up is best.
