Publication number: 20170318626Abstract: A self-regulating electric heater cable includes a monolithic heater core of PTC material encapsulating a pair of bus wires, and a conductive layer disposed on an outer surface of the heater core such that the conductive layer levels the voltage generated at the outer surface of the heater core when an electric current is passed through the bus wires. The conductive layer draws the current evenly through lobes of PTC material encapsulating the bus wires. The conductive layer may be a coating, such as a conductive ink or paint, or may be an extruded or wrapped material applied to the heater core. Standard heater cable layers are applied over the conductive layer, including an electrically insulating layer that contacts a portion of the conductive layer and also may be separated, at points, from the conductive layer by one or more air gaps.Type: ApplicationFiled: May 1, 2017Publication date: November 2, 2017Inventors: Mohammad Kazemi, Peter Martin, Linda D.B.

Publication number: 20160234884Abstract: A self-regulating heater cable includes a PTC core formed of positive temperature coefficient material and disposed in electrical contact with at least two bus wires. The PTC core may encapsulate the bus wires and space the bus wires apart a predetermined distance via a connecting portion of the PTC core. The connecting portion has a tapered profile, and is thinner at the ends approximate the bus wires and thicker in a portion between the ends, which portion may be toward or at the center of the connecting portion. The thicknesses of the ends and the thicker portion are selected to produce a ratio that is within a range at which the heater cable produces heat at its outer surface with a substantially uniform profile, and primary heat generation of the heater cable has not shifted from the center of the connecting portion to the ends of the connecting portion.Type: ApplicationFiled: February 9, 2016Publication date: August 11, 2016Inventors: Mohammad Kazemi, Linda D.B.
