Abstract

Techniques for designing and creating energy efficient cookware are provided. In accordance with the techniques cookware can include a base and a wall and a linear pattern of flame guide channels connected to the base bottom. The guide channels accept flames and guide them to the perimeter from the central region resulting in efficient heat exchange. The linear channel profiles provides significant surface area enhancement from a given area on the bottom to improve heat transfer while providing even heating and mechanical strength to the cookware. A flame entrance opening is provided in the center region of the base to allow easy entrance of the flame into the channels. A gas burner flame pattern is provided to work with the linear channels profiles of the cookware to further improve the energy efficiency. A method of making the efficient cookware is provided involving deep drawing an extruded fin plate; A method of making the efficient cookware is provided involving spin cutting and spin forming of an extruded plate. A plate with heat exchange features that can be used either as the base of a piece of cookware or attached to the base of a piece of cookware can improve efficiency of heat transfer to the cookware.
