I've just finished throwing together a cold air box, it cost me nothing, for everything had been sitting in my garage for years. Had a couple of esky's to choose from, an old fan with variable control, and used an old aluminium car filter housing for the air to exit through.
The esky stays nice and sealed with no leaks, and the fan just blows cold air through the duct. I can fit 3x ice packs right into the filter housing, and i just load up the esky with frozen bottles which are filled with salt.
If i keep my hand in the duct for a minute, it goes icy cold.
This is going to be for my next extraction, and it only took around an hour to build.
You could really load it full of ice if you had to, for its a nice sized esky, but its very effective with just a few ice packs thrown in and some frozen bottles.
I'm going to modify it soon which will have copper pipes inside the esky, and will have cold water pumped through them, which of course will work even better and will actually cool down a room in summer if need be.
