Abstract:
A heating device includes a substrate (1) added with a functional far infrared material, an electrothermal film layer (2) coated on a surface of the substrate (1), and two electrodes (3) mounted on two opposite sides of the electrothermal film layer and each electrically connected to the electrothermal film layer. Thus, the electrothermal film layer co-operates with the functional far infrared material contained in the substrate to produce heat by conduction of the two electrodes so as to heat an object to be heated, thereby simplifying the construction of the heating device, and thereby enhancing the heating efficiency of the heating device.
Abstract:
Disclosed is a far infrared ray hair dryer consists of a housing (2), a hand grip (3), an air inlet (21) and a wind outlet (24) respectively at one side. A fan motor (22) equipped in the housing is for blowing the air, and a porous ceramic honey comb heater (4) installed in the housing is for radiating far infrared ray when heated and together with hot or cold wind to apply on the user's hair.
Abstract:
A far infrared tubular porous ceramic heating element which is suitable for various kinds of catalyst, heater and electric conductor... etc. Inside the body, a plurality of via holes is formed, and the crossing portions of the walls of via holes are formed in arc shape so as to prevent breaking and disturbance to heat flow.
Abstract:
Disclosed is method of fabricating semiconductor heater film which is formed on a substrate with excellent heat resistant and electrical insulation property by depositing atomized particles of coating material essentially formed of powdered metallic (Sn,V) chlorides and silicide mixed with one of Fe, Sb or In compound and solvent such as water, methyl and ethyle alcohols, hydrochloric acid, sulfuric acid, also small amount of non-organic acid is added to intensify the chemical affinity of the coating material.
Abstract:
A porous ceramic carrier includes a main body (2) having an inside provided with a plurality of intersecting separation walls (21) formed with a plurality of through holes (20), wherein the separation walls (21) have connections each formed with a cylindrical portion (22). Thus, each of the through holes (20) of the separation walls (21) has smooth corners instead of sharp corners so as to reduce the stress applied on the surface of each of the through holes (20), thereby preventing the connections of the separation walls (21) from being worn or broken due to a stress concentration.
Abstract:
A film heating element includes a substrate (1), an electrothermal film layer (2) coated on a surface of the substrate (1) and made of a material having a PTC effect, and two electrodes (3) mounted on two opposite sides of the electrothermal film (2) layer and each electrically connected to the electrothermal film layer (2). Thus, the film heating element has a simplified construction and does not need a temperature control.
