• H05B 3/36 - Heating elements having extended surface area substantially in a two-dimensional plane, e.g. plate-heater flexible, e.g. heating nets or webs heating conductor embedded in insulating material
• H05B 3/14 - Heating elements characterised by the composition or nature of the materials or by the arrangement of the conductor characterised by the composition or nature of the conductive material the material being non-metallic

Abstract

The present invention relates to a planar heating composite sheet including: a planar heating layer including a base sheet made of a synthetic resin material and having a predetermined width and length, a plurality of electrodes coated to an upper surface of the base sheet along a width direction of the base sheet, with different polarities being alternately arranged at regular intervals along a length direction of the base sheet, a conductive paste coated entirely between the plurality of electrodes on the upper surface of the base sheet and generating heat by electrical resistance, and an insulating sheet made of a synthetic resin material and attached to an upper portion of the conductive paste; and a heat insulating layer including a heat insulating sheet attached to a lower portion of the planar heating layer and including a non-woven fabric impregnated with aerogel, and a protective sheet made of a synthetic resin material and attached to a lower part of the non-woven fabric sheet. According to the present invention as described above, the loss of heat into the ground is prevented more efficiently such that the heat transfer efficiency in the upward direction is greatly improved, and accordingly, when applied to the snow melting pavement of the road, the snow melting efficiency is remarkably improved, and subsequently, the power consumption can also be greatly reduced. Further, the present invention can reduce maintenance costs of re-construction as damages caused by asphalt concrete or equipment load applied during snow melting pavement construction and wheel load applied after construction can be prevented more efficiently.
