Abstract
A novel solid-state heating element is disclosed. The heating element comprises a plurality of heating layers comprised of a mixture of carbon and a polymer or plastic. The heating layers are disposed on or infused into a substrate. Each heating layer can be disposed on, or infused into, its own substrate, or the heating layers can be disposed on or infused into opposites sides of the same substrate. A radiating element can be disposed in proximity to one or both of the heating layers. The radiating element absorbs the radiation put out by the heating layer(s) and reradiates heat. A heat transfer fluid such as air or a liquid can be directed across the radiating element and/or other areas of the heating element to transfer heat from the heating element to another location.
Claims20
A solid state heating element, comprising:
- a plurality of heating layers, each heating layer comprising a mixture of carbon and a polymer, each heating layer disposed upon a substrate layer;
- and
- the plurality of heating layers oriented to be in close proximity to each other such that infrared radiation produced by one heating layer impinges upon another heating layer.
A system comprising:
- a housing;
- a heating element disposed within the housing, the heating element comprising:
- a plurality of heating layers, each heating layer comprising a mixture of carbon and a polymer or plastic;
- the plurality of heating layers oriented to be in close proximity to each other such that infrared radiation produced by one heating layer impinges upon another heating layer;
- and
- an insulating layer disposed between the plurality of heating elements;
- a flow channel surrounding the heating element conducting a heat transfer fluid past the heating element thereby conducting heat from the heating element to the heat transfer fluid;
- and
- a power supply connected to the heating element to cause current to flow within the heating layers of the heating element.
