Description

Heat generation device using carbon fiber {HEAT GENERATING APPARATUS USING CARBON FIBER}

The present invention relates to a heating device using a carbon fiber as a heating element, and more particularly, the carbon fiber is made of a strip-shaped plane heating element, which is easy to use, such as sewing, without a separate coating on clothing, bedding, etc., which are adjacent to the human body. It relates to a heating device using a carbon fiber to be built.

In general, electrothermal heaters provide heat energy for heating, keeping warm, etc. by using heat generated when a current flows to a conductor having a resistance of a predetermined size. It has the advantage of no noise due to operation, so bedding such as bed mattresses and thermal blankets, heating devices for buildings such as houses or offices, agricultural equipment such as vinyl houses or agricultural product drying systems, melting snow on roads and parking lots It is widely used throughout the daily life, such as various freeze protection devices that can prevent the freezing or freezing, as well as leisure, cold protection, home appliances, anti-fog device of mirror or glass, health supplement, animal husbandry.

1 is a schematic view showing a conventional electric blanket using a wire-type electric heater among the electric heaters described above.

In the conventional electric blanket, as shown in Figure 1, between the outer shell 110 is filled with a heat insulating material (120) serving as a cushioning function such as cotton or non-woven fabric, the heating wire twisted spirally between the heat insulating material (120) 130 is arranged. The heating wire 130 is a nichrome heating wire, a copper nickel alloy heating wire, a heating wire etched a metal thin plate such as aluminum, etc., the outside of the heating wire 130 is coated with an insulating synthetic resin (131).

By the way, the conventional electric blanket is a structure in which a current flows through one heating wire 130, so if any part is broken, electricity does not pass through the entire heating wire 130, so that the heating operation cannot be performed. The outer surface of the 130 is coated with a very low thermal conductivity coating material has a problem of low thermal conductivity efficiency. In addition, a large amount of harmful electromagnetic waves are generated according to the flow of current through the heating wire 130, in particular, in the case of an electric blanket used in a state in which the magnetic field is more severe among the electromagnetic waves is used in direct contact with the human body There was a problem that increases the risk for.

In addition, the heating wire 120 is built into the garment to obtain a predetermined cold effect, proposed 'cold clothing with electric heating device for transportation equipment with a power generator' (Utility Model Registration No. 20-0222210) It has been.

However, since the conventional cold weather clothing uses a metal heating wire as a heating element in the same way as in the case of the above-mentioned electric blanket, there is a problem of low heat conduction efficiency and a large amount of harmful electromagnetic waves. There is a problem that the visual activity is displayed through the outer shell of the garment to reduce the aesthetics of the garment or cause unpleasant touch to the wearer, and the activity at the time of wearing is restricted to prevent the electric wire from being broken.

Therefore, the present invention has been devised to solve the above-mentioned problems, and the heating part is made of carbon fiber and easily embedded in clothing, bedding, etc., which are in direct contact with the human body, and has high thermal conductivity, and prevents generation of harmful electromagnetic waves. It is an object of the present invention to provide a heating device using carbon fibers, which can improve the wearing comfort.
