  • Patent number: 8927910
    Abstract: An electrical heat production device comprising a thin resistive layer sandwiched between a pair of plates having high thermal and electrical conductivity, the stack of layers being insulated around the side surfaces. When a voltage potential is applied across the plates in the disclosed electrical heat production device, an electrical current flows across the resistive layer producing heat within the resistive layer that is conducted through the plates and across the outer surfaces of the plates. A guard heater can be positioned adjacent to one of the outer plate surfaces to bias the heat flow from the resistive layer toward the opposite outer plate surface, such that the apparatus can have a single planar heating surface.
