TEC (Peltier)-cooled Canon 450D DSLR

TEC (Peltier)-cooled Canon 450D DSLR

Here’s an upgrade of my previous TEC-cooled 450D project. It uses a cold copper plate mounted directly at the back of the imaging sensor, which is then cooled by a stack of 2 Peltiers, one being more powerful than the other (40 mm and 30 mm modules). Non-electrically conductive thermal paste (Zalman) has been used to promote effective heat transfer and yet avoid electrical hazard.  A12V 12A DC adapter powers the fan, Peltiers, and the heater.  A standard Canon adapter powers the camera.
