• Oven cooling and heating is yet in developmental state. Cooling must be fast enough and also heating in order to follow the preprogrammed temperature curve. The outer of the oven chamber inside oven must be isolated with woven class fiber cloth and aluminium foil for fast enough temperature rise.

  • Here is my idea for heat escape vent. This resist hot air escaping backside out through the cooling fan during heating process. I have decided to build tunnel few cm long between oven back and cooling fan. Inside the tunnel there is an aluminium wall with several holes and very thin round aluminium plates as vents connected with pivots on top of holes and to wall.

  • When cooling fan starts the air pressure opens these vents automatically. The pivots must not resist the plates movement, but heat escape. So they must be sensitive, perhaps made of Kapton tape. The wall inside tunnel have to be in angled position in order to vents be closed(earth gravity) when fan is not operating. The size and amount of vent holes depends on air flow needed. Also the oven door should be automatically opened enough during cooling process.
