Hi Ken
I can't see exactly what you've done here, but are you attempting to cool the actual CCD chip, or just the back of the case? I tend to think that the insulative qualities of the plastic - as well as the air gaps within the camera - will serve to utterly insulate your efforts from where it counts - the CCD itself.
I'm looking at cooling my ToUcam as well. From what I have read you need to literally remove the CCD array from the PCB by extending the contacts via ribbon cables. At that point you can mount the CCD on a cold "finger" of billet aluminium, with a thermal transfer paste between them to make thermal conductivity more efficient. Then you use a peltier device to cool the finger and a fan to cool the peltier.
Looks like a big job, but I'm willing to give it a go....
Cheers
Chris
