Problems solved by technology

[0004] However, the current flow at the power input point of the existing plate-shaped heating element is relatively large, so local overheating occurs at the power input point, and the heat generated at the far position between the power input point is relatively low, Therefore, there is a problem of non-uniform heating over the entire surface of the plate-shaped heating element.
Therefore, it is difficult to apply the existing plate-shaped heating element to equipment requiring uniform heating

Abstract

The present invention relates to a plate-shaped heating element that generates heat by using graphene or the like as a conductive heating substance. The plate-shaped heating element according to the present invention includes: a first electrode connected to one side of the power supply; a second electrode connected to the other side of the power supply, at least a part of the first electrode and the second electrode The cross-sectional area or the distance between the bifurcated electrodes is determined in such a way that the resistances of the plurality of circuits composed of the first electrode, the heat-generating substance, and the second electrode are theoretically the same, and, in A bridge mediating the flow of electrical current is included between the first electrode and the second electrode. According to the present invention, the electric current flows evenly through the heat-generating substance located between the two electrodes to generate uniform resistance heat, thereby improving the applicability of the plate-shaped heat-generating body.

Description

technical field [0001] The present invention relates to a plate-shaped heating element using graphene or the like as a conductive heating substance. Background technique [0002] Generally, plate-shaped heating elements can be applied to the glass surface of refrigerated showcases, window systems, automotive glass surfaces or liners, bathroom glass, rice cookers, etc. [0003] Generally, a plate-shaped heating element is coated with a conductive heating substance such as graphene on a non-conductive substrate, and is formed, for example, in a structure in which a first electrode serving as a + electrode and a second electrode serving as a - electrode are combined. And, when a direct current or alternating current voltage is applied to the first electrode and the second electrode, the electric current flows through the conductive heat generating material to generate resistance heat. [0004] However, the current flowing at the power input point of the existing plate-shaped h...
