Update with few more images.
The support frame was 3D printed (I only had red filament left). The hex-head bolts were heat-pressed into it. Nuts were screwed on the heatsink side after drilling the thread out on the heatsink. Cooler is ID-COOLING Iceland Series IS-50.
I ran a quick test and got to -2C within 2-3 few minutes (ambient temperature was about 20C). It could have gone lots lower but I stopped it because of possible condensation inside (it is just on my desk).
Todo:
- The fan on the heatsink is oversized. This may be a good thing to keep the camera warm or even to redirect this airflow onto the field flattener to keep it warm, instead of using heating tapes.
- Also may need some rubber supports for the fan to reduce vibrations.
- Bag the whole thing and fill with Argon.
- Finish the PWM software controller.
