Couple of wine cooler incubator questions.

[jeff6898]

What am I looking for when I buy the fan for my incubator? Just any computer type fan? Does it need to be 12v or somehting else? Does it splice into a regular extension cord or something like a phone charger?

For the heat tape cord, temp prob ect is it best to drill the hole through the back or top or does it matter? Last question, what do you seal the hole with? I imagine it needs to be sealed good to keep heat from escaping.

Sorry for all the questions, just want to do this the right way.

This is where I purchased my fan.

I read that some fans give off heat so they raise the temps in the cooler. You want to look at CFM's also. 12V fans need a converter like a cell phone charger and 120v plug right in to an outlet. If you go bigger you can use a dimmer to slow the fan down. If the fan is too small you can't speed it up.

My problem right now is placement of the fan to provide even temps throughout.

We used this as a power supply and it was purchased at Fry's Electronics:



The variable supply allows me to speed and slow the fan as necessary.


When looking for fans I choose ones with low noise ratings but almost any medium sized case fan will work.

We place our fans on the bottom of the inc and use a rheostat to control the fan speed.
We use a bathroom ceiling fan on a dimmer/rheostat to slow the speed down, it's how we fine tune our airflow so that top to bottom temps are within 1 degree.
We have also now gone to using a false wall in the back to keep the heat tape away from any tubs.
The fan blows into the false wall at the bottom pushing air over the heat tape and then the heated air comes out the top of the false wall and into the incubator to be pulled back down to the fan.

No heat tape exposed to the inside of the incubator, so far this inc is running almost dead even with the temps from top to bottom within 1 degree.

What is your false wall made out of?

I wonder if ported vents up the false wall would be better then just venting through the top?

Great Stuff in a spray bottle does a super job at sealing the hole. Also, I second the coolerguy.com site for a fan. You can buy a cord with a rheostat built into the cord.
