I have heard some friends have had success using a 12v computer fan...helps move the air without an enormous current draw.

From memory my one does something like 6 or 8m3/h.
I have mine mounted to force air across the condenser coil when the fridge is inside the trailer.
But you could easily just fit a filtered inlet on one corner of your box and a blower fan as an outlet on the opposite corner to force a draft through.
Would just want to make sure the filter on the inlet is well sealed and easy to remove/clean.

I use a blower fan from a 3D printer, they’re still as cheap as computer fans but move heaps more air.

Wanting to rig up something like that in the shed to help keep it usable :'(
Got a link, Pete ???

Got a link, Pete ???
But there’s heaps of cheap ones on eBay these days.
Pretty sure this is the one I have;

Edit;
Just re-read your post.
I assumed you meant to setup the blower for the fridge in your shed.
I’d say these little fans won’t move anywhere near enough air for you working in your shed. Maybe if you have it blowing right in your face while you’re sitting at the bench.
This bad boy doesn’t even move enough air to make my shed more usable some days..... ;)

Yeah, I was thinking of something to just suck in cool air at one end, where there's nice shade, while another one pushes hot air out the other end, so it's hopefully bearable, but looks like it may be back to the drawing board ???

Hession cloth hung over window openings set up with a dripper to keep it wet [ AKA Koolgardie safe style ] and a recovery tray to recycle the water ... mount a fan on the inside of one or more of the open windows to help draw air in ..
Two big as you can get thermo fans [ wreckers / dump / ebay ] rigged up via battery and solar panel venting up in the roof to vent heat out, if you have a ceiling ad large screened vents to the eaves .. My neighbour did this and said he got roughly 5 > 9* deg C cooler
difference in his roof space ..
If water IE: Stand alone for the shed > tank water.. Rig a solar powered pump to run a couple of soaker hoses over the roof and cycle it back through the tank .

1 blowing air in and the other sucking it out. Connect them to a thermostat switch and that should keep enough air circulating around. The fridge itself will move a bit of air as the compressor fan kicks on and off
