An oven (400, 500) comprising: a compartment enclosed on all sides and defining an interior therein; a heating element operable to heat air within the interior of the compartment (100, 200, 400, 500); a fan (460, 560) disposed in fluid communication with the interior of the compartment, the fan operable to cause air to flow across the heating element and toward a front region of the compartment; a panel disposed at the front region of the compartment; a vertical divider (440, 540) dividing regions of the compartment through which air flows in opposite directions from one another, the vertical divider (440, 540) disposed parallel with a direction of airflow on either side of the vertical divider (440, 540), the vertical divider (440, 540) providing an opening (445, 545) at the front region of the compartment to facilitate air flowing from the fan (460, 560) to the front region of the compartment through a first region (470, 570) adjacent the vertical divider (440, 540), through the opening (445, 545) in the vertical divider (440, 540) at the front region of the compartment from the first region (470, 570) to a second region (480, 580) on an opposite side of the vertical divider (440, 540), and from the front region of the compartment toward the fan (460, 560) through the second region adjacent the vertical divider (440, 540); and a plurality of profile elements disposed on the panel facing the interior of the compartment, positioned in one or more arrays, and structurally configured to direct air received at the panel through the first region (470, 570), through the opening (445, 545) provided by the vertical divider (440, 540), and back toward the fan (460, 560) through the second region (480, 580) in a more uniform spatial distribution than would result from a flat panel. a compartment enclosed on all sides and defining an interior therein; a heating element operable to heat air within the interior of the compartment (100, 200, 400, 500); a fan (460, 560) disposed in fluid communication with the interior of the compartment, the fan operable to cause air to flow across the heating element and toward a front region of the compartment; a panel disposed at the front region of the compartment; a vertical divider (440, 540) dividing regions of the compartment through which air flows in opposite directions from one another, the vertical divider (440, 540) disposed parallel with a direction of airflow on either side of the vertical divider (440, 540), the vertical divider (440, 540) providing an opening (445, 545) at the front region of the compartment to facilitate air flowing from the fan (460, 560) to the front region of the compartment through a first region (470, 570) adjacent the vertical divider (440, 540), through the opening (445, 545) in the vertical divider (440, 540) at the front region of the compartment from the first region (470, 570) to a second region (480, 580) on an opposite side of the vertical divider (440, 540), and from the front region of the compartment toward the fan (460, 560) through the second region adjacent the vertical divider (440, 540); and a plurality of profile elements disposed on the panel facing the interior of the compartment, positioned in one or more arrays, and structurally configured to direct air received at the panel through the first region (470, 570), through the opening (445, 545) provided by the vertical divider (440, 540), and back toward the fan (460, 560) through the second region (480, 580) in a more uniform spatial distribution than would result from a flat panel.
