Abstract

An electromagnetic cooking device includes a cavity in which a foodstuff is placed. A plurality of radio frequency feeds are configured to introduce electromagnetic radiation into the cavity for heating the foodstuff. A radio frequency signal generator is configured to generate a low power radio frequency signal where a high power amplifier is coupled to the radio frequency signal generator where the high power amplifier is configured to amplify the low power radio frequency signal to a high power radio frequency signal. A heat sink is coupled to the high power amplifier where the heat sink includes a flat base coupled to a plurality of fins which extend perpendicularly from a first side of the flat base. A thin metal plate includes a plurality of perforations where the perforations are filled with an epoxy resin having a carbon nanotube loading.

Description

Technical field [0001] The present disclosure generally relates to methods and devices for electromagnetic cooking, and more specifically, to methods and devices for thermally adjusting components in microwave ovens. Background technique [0002] Conventional microwave ovens cook food through a dielectric heating process, in which high-frequency alternating electromagnetic fields are distributed throughout a closed cavity. The subband of the radio frequency spectrum, the microwave frequency at or near 2.45 GHz, mainly causes dielectric heating by absorbing energy in the water. [0003] In order to generate microwave frequency radiation in conventional microwaves, the voltage applied to the high voltage transformer results in high voltage power applied to the magnetron that generates microwave frequency radiation. The microwave is then transmitted through the waveguide to the closed cavity containing the food. Cooking food in a closed cavity with a single incoherent source (such a...
