System and method for improved convection airflow in a cooking appliance

A baffle wall for an oven air circulation apparatus comprising a first fan coupled to at least one motor that rotates about a first rotational axis in a first direction, a second fan coupled to the at least one motor that rotates about a second rotational axis in a second direction, opposite the first direction, wherein the baffle wall comprises:

• a surface arranged substantially perpendicular to the rotational axes of the fans;
• a plurality of first openings formed in the surface through the baffle wall and aligned with the first fan, wherein the first openings successively increase in proportion radially outward from the first rotational axis and in the first direction;
• and
• a plurality of second openings formed in the surface through the baffle wall aligned with the second fan, wherein the second openings successively increase in proportion radially outward from the second rotational axis along the second direction where the first openings are arc-shaped openings successively formed in the baffle wall concentrically outward from the first rotational axis and radially offset in the first direction.
