<p>Energy efficient cookware is provided including a base, a wall, and a linear pattern of flame guide channels connected to the base bottom. The flame guide channels accept a flame and guide the flame to the perimeter from the central region resulting in efficient heat exchange. The linear channel profile tends to maximum the surface enhancement from a given plain area on the bottom to improve heat transfer while providing even heating, and mechanical strength to the cookware. The impedance to entrance of flame flow into the channels is minimized to allow easy entrance of the flame into the channels. A reinforcement means is provided to strengthen the rim, therefore, the mechanical robustness of a cookware. A method of creating the reinforcement rim is also disclosed. A method of making the efficient cookware is provided involving die casting. A method of heating a fin structure is provided using an RF heater with complementary fin features.</p> |
