CARBON SURFACE HEATING ELEMENT OF A VALLEY BOARD STRUCTURE IN WHICH

摘要

PURPOSE: A carbon surface heating element and a manufacturing method thereof are provided to improve thermal radiation capacity and thermal keeping capacity by placing a buffer material between a rearward reinforcing material and a lower layer sheet material.;CONSTITUTION: A carbon heating element(20) is formed on a lower layer sheet material(10). A lead electrode(30) is formed on the carbon heating element. An upper coating material(40) is formed on the lead electrode. A groove(50) is formed on a carbon surface heating sheet except for a electric wire terminal connection part of a planar structure. A reinforcing material is attached to the rear side of a lower layer sheet material for reinforcing the strength of the groove.;COPYRIGHT KIPO 2012
