Thread: New Coffin Chiller

Tweet

I had some pine laying around so I thought I would upgrade my chiller. I used two foggers I had lying around instead of buying a new one, a 700 and 400 watt. Straight forward toe pincher with foam insulation all around. I put flashing on the deck with flashing lining the exit hole. I will elevate the "head" about 4" so as the ice melts it will simply run out the exit plus will help with the heavier cool air exiting. Had one on a smaller scale and it works great. I will try to post vids.

Love your cooler! The lid looks awesome too! If you don't mind me asking do you have the dimensions you used? I made a bookshelf following I believe Casa De Sade's toe pincher coffin directions, but I like the shape of yours slightly better!

I ran into problems cutting the angles where the tops parts mated.. Most people just but the edges together and don't cut the sides at an angle.. Can't quite make out what you did!

I like your design of having the screen at an angle between the fog and the ice. And room for two foggers, to boot!
I love it!

Nice !!!! I cant wait to see the vids.

Here are a few videos:

Brilliant, That thing is Awesome great work!!!!!

I like this design a lot, but what do you do with the water as the ice melts?

The water comes out where the fog does. The whole inside is lined with flashing along with the exit ramp. Simply just runs out the end. I elevated the head about 4 inches to assist with the fog exiting and for the water to drain. With this design, all water exits out.

What a great approach to comcealing the gear! Hide it in plain sight! I love it!

I really like this idea. I've been experimenting with different chiller designs based on some theories about how it works. The theories are basically

1. Fog needs to mix with fresh air.
2. Fog needs a space to expand in.
3. Fog is warm and rises
4. Chilled fog becomes more dense and falls.

I made a chiller out of a rectangular shaped ice chest. It has a foam divider between the two sides. The divider is about 2 inches short of the top of the ice chest. I cut a 3" hole in each end of the ice chest. The fogger is set outside of the ice chest and about 3" away from the entry into the chest. The fog mixes with fresh air and blows into the first chamber of the chest where it expands. From there it rises over the foam partition and down on to an ice covered wire mesh in the second chamber. Then the chilled fog settles in the bottom of the second chamber and exits the hole in that end. I believe this creates a natural draft from the foggers through to chilled exit. It works extraordinarily well with just one bag of ice.

I like how this has the foggers hidden inside. The angle of the wire mesh gives the fog some space to expand. One potential problem though with this design is that the foggers tend to blast the fog out towards the exit, where the hot blasted fog mixes with cooler fog and exits maybe not as cold as it could be.

What I would experiment with on this coffin chiller is inserting an expansion chamber between the foggers and the ice. The expansion chamber will help keep warm and chilled fog from mixing. When building the divider between the two chambers, leave a couple of inches for the fog to rise and spill over the divider. This will allow the fog to rise which will draw fresh air from the foggers and into the expansion chamber, then as it spills over the divider, it will be chilled and as it exits that chamber it will draw more warm fog over the divider.
