CERAMIC CARBON FIBER SHEET PLANE HEATER

摘要

PURPOSE: A ceramic carbon fiber sheet plane heater is provided to achieve different heating characteristics in vertical and horizontal directions, optimize uniformity of heating temperature, and improve heating efficiency and reliability. CONSTITUTION: A carbon fiber(2) has an oriented arrangement to have thermal properties in vertical or horizontal directions on a plane. The carbon fiber(2) is arranged on a pulp member(1). At least one pair of electrodes is formed in the vertical and horizontal directions of a carbon fiber heating sheet. Polymer insulating members of at least one layer are laminated on upper and lower surfaces of the carbon fiber heating sheet. A heat transfer medium of fiber or powder type is included in the carbon fiber heating sheet to prevent a thermal ununiformity between a high density part(6) in which a carbon fiber density is high and a low density part(5) in which a carbon fiber density is low. The carbon fiber heating sheet includes a heat transfer medium. The polymer insulating member includes a heat transfer medium.
