DIY Cattle Cooler questions

[Mcabram]

I have a steer, and he has pretty decent hair. I want to build him a little one calf cooler to put him in during the day. This is my senior year so I don't need anything per minant. I am keeping him at my school where he is in a steer pen next to a couple other steers. I have fans on him all the time. About 2/3 of his pen is dirt and the other third is concrete with his waterer. The concrete area is where I would block off to turn into a cooler (Ag teacher isn't a big fan of me building myself something on school property)

I am planning on using tarps to line the area of concrete, three sides, leaving one side open so the fans reach him, and the top. I have mats down on the concrete so he won't be on it all day long.

Does anyone have experience with this kind of method?
Anyone have any reasonable suggestions a high school senior could afford on her own  (lol)
Thanks in advance!

(He is a sim angus steer, 920 pounds, gaining 3.7 pounds per day, about a week into the show coat  solutions daily hair care routine, just in case anyone was curious! Nugget says thanks in advance too)

Misters and fans plus showcoat may be a better option and still grow decent hair. Coolers have to be watched carefully and can be expensive. IMO angus blood never equals lots of hair and simmi doesn't always help.

You aren't going to be able to get any R value from the tarps. Therefore an AC unit that is really pushing hard to get the room cold is going to likely freeze up trying to do so. Fans, Misters, and Showcoat are probably your best option. you could run a Hurricane Fogger with ice water, but that takes a ton of ice.

Take the money you'd spend on that contraption and use it to buy more fans, hoses, scrub brushes, and showcoat
