Hi all...
I'm building a cold smoker and could use some help.
(http://i1234.photobucket.com/albums/ff410/Wayne226/Cabinet.jpg)
The Cooling Box 6 X 9 X 12 inches will be attached to the Bradley Generator with two Bufallo Heat Pipe CPU Coolers. Above the Cooling box will be three 2-3/4 inch fans exhausting out of the cabinet.
See above.
The dimensions of the Cooling Box.
See below.

I'm not sure where to put the two heat sinks and the 5 inch Flex discharge pipe.
Here are some pictures as we all like pictures. Some time pictures are better than a thousand words.

The Heat Sink and the Smoke Pipe on top of the Cooling Box. A hole will be cut out for the pucks to drop through.

This is just a draft setup. I hope we can see the built Cooling Box in are minds to see what I'm getting at.

Not sure if the Flex pipe should be directly above the hotplate or off to the right of the hotplate, also not sure of the heat sink placement.
I hope this is understandable. If so your thoughts will be appreciated. :)
Later Fisher...
Very cool project Fisher!
Because heat naturally rises I would put the heat sink directly above the puck burner and have the exhaust over to the right. That would give the heat sink an opportunity to take away some of the heat before it goes through the exhaust and up to the smoker.
The only thing in your plans that I don't see, unless I'm over looking it, is an intake vent for the smoke generator. If you have an enclosed box that you are venting with your 3 fans you are going to need intake air otherwise you could create a down draft situation.
The other thing you might consider is having the spent puck bowl, or preferably larger pan, inside the enclosed box for the puck burner hot plate. This way if you choose to use another form of wood chips for a specific project you could.
Great looking project.
Mike
That is cool.
Very nice!

very cool project, I would increase the height of the box to match the height of the smoke generator because of the weight of the cold smoking box causing the smoke generator to tip, also need to consider the weight of the heat sinks, and duct work, and place the bowl inside ,, then add a door and place the bowl inside.
second idea is add support legs to the far end of the box to prevent the unit from tipping then cut a hole for the bowl under the puck burner
good luck

Thanks Mike for your thoughts.... I was going in the same direction too, with the heat sink above the puck burner and exhaust to the right. I should have been clearer on the lower cabinet with the three fans and the shelves to the right for the rack rotation. The left, right and back side of the cabinet will be closed in, with the front wide open. I do like the idea of a totally closed cooling box with the pan inside with a door.

Thanks beefmann for your thoughts. I like the idea of the cooling box with the bowl inside look like you and Mike are on the same page with that. I was trying to get away from using a door. Plans can be changed as you see this is only a draft setup. It was great that you picked up on the missing legs I forgot to draw them in when I drew up the plan.
Um... I marvel at your planning process and interest in getting it "just right"...however, what's wrong with a simple, air cooled, Bradley cold smoker box and 5" pipe? It works as advertised, and leaves you time to solve world hunger...<grin>
That thing looks like it can fly to the moon ;D

Tom...Nothing wrong with a simple cooling box. Being retired and the heat sinks and fans in a the junk box. I thought I would build something with this accumulating junk in the garage. It's good to stay busy when retired. It is to easy to just go out and buy a simple air cooled box.
I'd like to have an hour in your junk box ;D Very cool concept :)

I understand it well... nothing like a good project to keep the energy up!. Please post a complete tutorial when you get done! I might need a project in a few years.

Don't know if you could ever get it cold enough in Texas! LOL
Hi I finely got some work done on the cold smoke project. Sorry I took so long to add to the post. I had so much going the last month.
I did a dry run with just the hotplate, heat sinks and exhaust fans on. The outside/room temperature was 73F.
I will soon be doing the smoke run.
Here are the results of the heat run In a 5 minute interval and some Pictures.
Note: The cabinet temperatures is starting to stabilize at 55 minutes.
In Fahrenheit Start Temp 5 Min 10 min 15 Min 20 Min 25 Min 30 Min 35 Min 40 Min 45 Min 50 Min 55 Min 60 Min
Cooling Box Temp 66 69 75 83 87 89 91 91 92 92 93 93 93
Flex Pipe Temp 66 70 79 86 90 91 93 95 95 97 97 97 97
DBS Cabinet Temp 68 68 68 70 73 75 77 79 81 82 82 84 84
DBS Sensor Temp 65 65 65 66 68 70 72 74 74 75 75 77 77
on the Generator

5 minutes into the Temp test. The top number 75F is the Flex Pipe Temp and the bottom number 68F is the Temperature at the second rack from the top.

5 minutes 65F DBS sensor.

20 minutes in with the cabinet 73F. When the first puck would have dropped.
(http://i1234.photobucket.com/albums/ff410/Wayne226/888.jpg)
93F inside the cooling box one hour into the temp test.
(http://i1234.photobucket.com/albums/ff410/Wayne226/999.jpg)
Cabinet temp 84F one hour into the test and looks like the temp stabled.
I also received the Auber PID the other day and also ran a test. I had a high deviation in temperature so I ran the Auto Tune, wow the Auto Tune sure held the set-point but very slow to recover set-point after 4F change so I looked at the auto tune results and found the Integral was 998 witch was strange because the range is 0-900 and the derivative was 499, the range their is 0-300 so I did a manual tune.
Well I have to go now I will post the results of the smoke run. I'm looking forward to see how the puck burn results turn out.
And a Happy New Year To All
Looks great. If I may ask a couple questions. Being a computer geek did you add any of the silver paster on the heat sinks? For CPUs it makes a big differance. Also does the fan blowing the hot air from the fins onto the pipe heat it back up some?
Jim
Hi Jim
Yes I will be using a heat sink compound. I have not applied the grease to the base of the heat sink yet; I'm still at the experimenting stage and have to do the smoke run. At the last test the air blowing from the fins was quite cool. I was surprised on how low the heat was. Good thought on the silver paster Jim. When I apply the grease and it makes a change to the heat discharge, I can turn the heat sinks one quarter turn. I'm new at smoking, so I have a lot to learn and the Bradley site is the place to be. Everybody is Awesome on this site. When I first joined the Forum Quarlow welcomed me and he was right on all aspects you're all great people!
Wayne
Her is a picture of the compounds. I have not decide witch one to use.

It looks good but I have a bigger question....................
Do you have this setting inside your house?

The Big Question lol.....Yes I have it setting inside the house. I built it in the shop and then brought it home. I will be setting it up in the shed out back but it was snowing blowing cold so I put it in the house for now. I could not wait to test the heat run since it was only a hotplate. So the house it was. I hope this answers the big question. :)
