Since summer time is upon us, where I train it get's up to about 100 before we stop training the dogs. Heat exhausting is very dangerous so I was thinking that building an A/C like system into the dogs boxes would be awesome. I already have fans set up, but just moving hot air won't be enough. I was thinking that I could do one of two things, ice to cool the air either before the fan or after the fan would be great.

Here are pictures of my set up.

This is inside the box.



This is the outside.



I was thinking of purchasing one of these. You freeze it and the fan blows across it and cools the air.



Any ideas would be appreciated. Also, what about dry ice?
