Abstract
A carbon felt heating device is disclosed. The carbon felt heating device includes a carbon felt unit adapted to radiate heat upon supply of power, and power-connecting portions, which are provided at two ends of the carbon felt unit so as to electrically connect the carbon felt unit to a power source, wherein at least some of voids in the carbon felt unit are filled with resin or polymer.
Claims14
A carbon felt heating device comprising:
- a carbon felt unit having a plurality of voids and adapted to radiate heat upon supply of power;
- power-connecting portions, which are provided at two ends of the carbon felt unit so as to electrically connect the carbon felt unit to a power source,
- a housing having a hole or groove corresponding to a shape of the carbon felt unit so as to allow the carbon felt unit to be fitted into the hole or groove in the housing,
- wherein at least some of voids in the carbon felt unit are filled with resin or polymer, and
- wherein a waterproofing insulation layer is formed both on a surface of the carbon felt unit that is exposed to the outside of the housing and on an outer surface of the housing.
