  • Patent number: 11812894
    Abstract: Apparatus and associated methods relate to a highly portable grill having an outer casing enclosing an inner cook box that acts as a heatsink to dissipate thermal energy, the outer casing being mechanically attached to the inner cook box at attachment points that function as thermal chokepoints for controlled conduction of thermal energy. In an illustrative example, the inner cook box may be mechanically attached to the outer casing via complementary screws and bosses to provide a limited thermal conduction pathway. The inner cook box may include a plurality of fins for added thermal energy dissipation. The outer casing may include a plurality of convection apertures to facilitate convective flow of thermal energy from the inner cook box to an external ambient environment. A limited thermal conduction pathway may beneficially allow the outer casing to be safe-to-touch while the inner cook box is still in use.
