Wiring a fan for a fridge

[oxfordshirestalker]

Hi folks,

I’ve got a new to me domestic fridge (yes, I know not ideal) which I’m going to use as a short term chiller, as and when I need it.
I want to put a small 12 volt computer type fan in it to circulate the air.
How is it best to wire these in?

Thanks

To avoid some sort of transformer could you wire to a small rechargeable 12v battery? Even a small battery would last for ages

Or a USB one - 5V

Well first things first. The domestic fridge will be 230v AC ( Alternating current), and your battery is 12v DC (Direct current), therefore you will have to source a small AC fan, or use an inverter to convert the the fan to an AC. Do I assume there is no mains supply to the location?. Maybe if you expand your requirements others on this site may have a better solution.

Good luck

Thanks all
I’ve got a normal domestic supply to run the fridge.
All I want is a fan in there to circulate the air a bit.
Maybe a battery powered cab type fan would do the trick. Or, as someone suggested, a usb fan.

Just looking to see what others have done.

Couldn't you perm wire the door switch and tap into the internal fridge light.

Cabinet fan 12/230v with transformer I use one on my annealing box to cool the motor down. pop a hole mount the fan/s run the cable out seal it up plug it in job done.

I use a USB fan as previously mentioned. It just plugs into an old usb style phone charger. The cable is so small I just put the cable through the door and the door seal covers it no problem.

I mounted it in one of the door trays so it’s solid in its position. It moves the air round with no issues. The toughest part to a domestic fridge set up is getting a consistent temperature.

Thanks all, I think I’ll go for the usb fan option.
Considering using one of the ink bird temperature controllers as may use it for home brewing too (after a good clean out)

This is the one I use

Can i ask why you would want to fit a multi speed fan in a fridge, i would just wire a 240volt fan or 2 and let it rip.

No need for it to be multi speed, I’m after a simple option!

 

[sikadog]

The main thing you need is moving air,it depends how competant you are at diy.
I would mount 2 x 240v computer fans horizontal about 50mm from the top of the box blowing upward. So they drag the cold air upwards. Then you nead to wire them into the interior light wiring after disconecting the door switch so they work constantly.

because we're not all fridge engineers OR electricians . I got one because it had a plug on already and ready to go

 

[sikadog]

Its a strange old world, when i started work, I was a joiner, then I learned how to be a plumber, then an electritricion and then a brick layer, then a fridge engineer, oh and I forgot a mechanic and a welder.
If someone wanted something doing i learned how to do it.
Im not a good cook and I dont repair electronics, but up until I turned 65 I never said i cant do that.
I found out how, we should all try and learn something new every day.

This! ^^

This is the USB I use -

Drill a hole in the side being careful not to hit any wires, pass usb wire through and silicone up the hole, fit fan and plug in, maybe with a timer plug to make it work for periods of the day.

Same approach if you want to control the temp outside of normal fridge range with a separate thermostat or change the humidity via an agrometer and humidifier unit.

Just don’t hit the fridge wires!!!
