    摘要: An electric heater includes a substrate; a first plane heating element disposed on a surface of the substrate; and a second plane heating element disposed on the surface of the substrate so as to be located outside the first plane heating element. The first plane heating element includes a first pattern portion having a start point and an end point, and a pair of first electrode portions connected to the first pattern portion. The second plane heating element includes a second pattern portion that surrounds a portion of an outer circumference of the first pattern portion, has a start point and an end point, and has an opening portion at one side thereof; and a pair of second electrode portions connected to the second pattern portion.

    摘要: A resistance heater may include a polymer positive temperature coefficient (PPTC) material, arranged in a PPTC body defining a heater main surface. The PPTC material may include a polymer matrix, the polymer matrix defining the PPTC body, and a graphene filler component, disposed in the polymer matrix. The resistance heater may include an electrode assembly, comprising a first electrode and a second electrode arranged in contact with the heater body at two or more locations, a first lead, connected to the first electrode, and a second lead, connected to the second electrode. As such, the electrode assembly may define a current path between the first lead and the second lead, the current path comprising a first portion, extending along the heater main surface, and a second portion, extending through the heater body.
