David this fridge is just a small step in the evolution of the fridge I really want to build. The Canon 5DH's sensor temperature even inside a fridge at -5C is 12C!
The real advantage of my design is that the sensor is the hottest thing inside the fridge so there is NO condensation on the sensor.
I theoretically can get the temperature inside the fridge to about -15C with this system but the freezer cannot cope with the heat load sustainably when ambient is high. I could start to minimise heat leakage by improving the insulation or get a bigger freezer. I will wait until I have fully tested this system.
Even with a camera ambient of -15C the sensor is at 2C.
If you notice I am collecting data at 1600 ISO.
Below are some more pictures of the new fridge along with one of the air cooled fridge. I also put two 200mm 12V fans on the freezers condenser. The compressor then runs far cooler.
