Problems solved by technology

But because electrical insulators are usually also thermal insulators, the heating efficiency of sheet heaters utilizing electrically insulated durable heating wires is actually reduced
[0006] Also, the temperature distribution on sheet heaters utilizing durable heating wires is not uniform because heating in the sheet heaters is limited to the vicinity of the heating wires
Also, sheet heaters utilizing durable heating wires such as nichrome wire are not suitable for radiant heating because metals have low emissivity of far-infrared radiation and have low efficiency in converting electrical energy into radiant heat

Embodiment Construction

[0021] Description of the preferred embodiment

[0022] figure 1 and figure 2 A plan view and a cross-sectional view of the carbon fiber-embedded heating paper constituting the present invention are given respectively. In the carbon fiber-embedded heating paper, carbon fibers (1) with a diameter of 5-50 μm and a length of 0.5-20 mm are dispersed in the pulp (2) in a preferred linear arrangement along the longitudinal direction of the heating paper.

[0023] For the carbon fiber-embedded heating paper, pulp rather than polymer is used as the base material to disperse the carbon fibers. Pulp does not soften in contrast to polymers such as fluorocarbons, polyesters, polyethylene, PVC, and polypropylene that soften at elevated temperatures. Therefore, a sheet heater using pulp as a base material to disperse carbon fibers can be used at a higher temperature than a sheet heater using a polymer as a base material. In addition, paper composed of pulp has higher ...

Abstract

This invention is related to the carbon fiber-embedded heating paper and thereof sheet heater. The alignment of the carbon fibers is controlled to give different heating characteristics to lateral and transverse directions of the said heating paper, which improves a variety of adaptabilities by using the said heating paper. The present invention is to provide the heating paper where the pulp is fabricated in the carbon fiber to have heating characteristics to lateral and transverse directions and the sheet heater comprised of the polymer coating to have electrically insulating characteristics. A variety of characteristics can be obtained from the sheet heater in case of need.

Description

Background of the invention [0001] 1. field of invention [0002] The invention relates to a heating paper and a sheet heater thereof, in particular to a heating paper embedded with carbon fibers and a sheet heater thereof. [0003] 2. Description of prior art [0004] Since the sheet heater uses electricity, it is easy to control the temperature of the sheet heater without polluting the air and making noise. Therefore, sheet heaters are widely used in heating mats and pads, heated quilts, heated mattresses, heated blankets, and heating systems for houses and apartments. In addition, sheet heaters are also widely used in heating systems for commercial, industrial, public, military, and agricultural facilities. In addition, sheet heaters are used in a variety of applications, including commercial and domestic heating and drying systems, frost protection and snow melting systems for roads and parking plants, heated products for leisure and cold protection, anti-fog syste...
