Abstract
Techniques for designing and creating energy efficient cookware are provided. In accordance with the techniques cookware can include a cookware base having a cooking surface and heating surface. The heating surface can have a pattern of fins forming heat exchange channels. The fins can effectively increase surface area and the channels can guide thermal energy to the perimeter of the cookware base while the fins absorb the thermal energy. The channel fins can improve energy transfer while providing even distribution throughout the cooking surface. The use of fins can also improve the mechanical strength to the cookware. Methods of making the energy efficient cookware are provided. A piece of cookware with a thick base can be provided by casting and by bonding a metal plate to the cookware body. Within the base, heat exchange channels are created by manufacturing processes such as casting or cutting to improve heat transfer.
