Abstract (en)

[origin: EP2647308A2] The device (4) has flow channels (10a-10g) extending in a flow direction (6) for feeding gas. Heating units (12a-12c) are operated independent of each other and attached to the flow channels (10a-10c). The heating units are formed to heat the gas flowing through the flow channels attached to the heating units. The heating units comprise temperable heating elements arranged within the flow channels. The heating elements are thermally connected with a solid body and embedded in the solid body surrounding the flow channels. An independent claim is also included for a hair dryer.
