Simple cooler for DSI
Posted 23 May 2008 - 09:25 AM
A small pond pump circulates ice water from an insulated lunch bucket type container. Water flow is controlled by a dimmer control on the pump [fan type].
I can easily get 2 hours of cooling with this setup. I can add more ice if needed. The DSI temp readout goes from 30C to 15C or lower in about 30 minutes with the pump running at about 50%.
Total cost about $70.
Tubing can be ordered from McMasters.

You can also use some of the liquid cooled CPU blocks.
There are many ways to do it and I say use what works best for you.
Thanks for sharing.
PS if you have any trouble with anything fogging up I have a trick ill share to keep the chip from fogging.

What is the trick? Fogging up is the limiting factor as to how cold I can go. Can't go below the dew point since the unit is unsealed.

This requires drilling 2 holes in the dsi case.
An air inlet and an air oulet.
As the DSI isnt an air tight unit you want the inside to be moisture free.
You can pick up dissicant from a hardware store
They sell it to keep basements or damp places moisture free.
Add the dissicant to a jar or can
get a fish tank air pump and run the hose to one side of the can.
On the opposite side add the hose and run it to the DSI.
You can add a small bleeder hose to the other side of the dsi but you may not need to.
What this does is the air from the air pump pumps air into the dissicant.
The air runs through the dissicant drying it out and then puts dry air in the dsi.
This way you can run your cooler as cold as you want and the chip shouldnt fog up as there is a constant flow of dry air going across it.

Could you skip the chilled waster portion and just run air through a jar of ice then to the jar of dissicant so that you fill the camera with 35-40 degree air?
