1. A convection oven, comprising:
an oven cavity defined by at least by a top wall, a left side wall, a right side wall, and a door configured selectively open and close the oven cavity; and
an air channel defining a convection airflow out of and back into the oven cavity, the top wall defining an air inlet to allow the convection airflow to enter the air channel from the oven cavity, the walls further defining a plurality of outlets to allow the convection airflow to exit the air channel and reenter the oven cavity, each of the plurality of outlets defining an elongate recess having a semi-annular surface, the recess extending into the air channel away from the oven cavity such that the recess is inset into the air channel, the plurality of outlets including a first outlet along the left side wall and a second outlet along the right side wall thereby providing a stereo circulation pattern, and at least one outlet along the top wall,
wherein each of the plurality of outlets houses a corresponding one of a plurality of heating tubes, each corresponding heating tube being axially mounted within a correspondence recess along the airflow exiting the air channel.
