There is an internal vent on wall ovens. Prior to 2007: Oven is vented through a vent tube under the control panel. After 2007: For single and double wall ovens, the vent is below the door to keep electronics cooler, improve appearance, and provide a better door seal at the top.

ovens are vented one way or another. You would not want to heat up the air in a sealed chamber because of thermal expansion. It would explode due to the heat expanding because it has no way to vent. A vent is also needed to vent fumes and by products that burn off during the self cleaning process.
that heat created in the baking process is mostly wasted , small fraction goes into the food.
