HEATING DEVICE FOR VEHICLE

摘要

An electric heater (7) is individually arranged at a position immediately upstream of a blowing port (6) that blows an air fed by a blower (4) into a vehicle room. The electric heater (7) is formed of a cylindrical case (15) loaded in the blowing port (6) and a heat generating sheet (16) arranged in the case (15). The heat generating sheet (16) is formed of a conductive fiber sheet obtained by making a carbon fiber into paper. Furthermore, the heat generating sheet is formed into a continuous strip and radially folded along pins (22) of the case (15). The air is heated while flowing along a surface of the heat generating sheet (16).

主权项

1. A heating device for vehicle, in which an electric heater is individually arranged at a blowing port from which an air fed by a blower is blown into a vehicle room,
wherein the electric heater has a structure in which a heat generating sheet, which generates heat by supplying electricity thereto and is formed in a strip shape, is received in a case such that the heat generating sheet is folded twice or more and that a surface of the heat generating sheet is made to be along a direction of a flow at the blowing port.
