Abstract
A heat exchanger for a cooking system is provided. The heat exchanger includes a central axis and a combustion chamber. The combustion chamber includes a central flow path, an inlet manifold, and an outlet manifold axially spaced from the inlet manifold. The inlet manifold and the outlet manifold extend annularly about the central flow path. A plurality of outer walls extend axially between the inlet manifold and the outlet manifold, wherein the plurality of outer walls are arranged about a radially outer perimeter of the central flow path. A burner assembly includes one or more burners that are configured to emit a combusted air/fuel mixture into the central flow path.
