Problems solved by technology

However, electrodes using metal sheets, metal wires, metal films, indium tin oxide (ITO) layers, antimony tin oxide (ATO) layers, conductive silver glue layers or conductive polymer layers as surface heat sources have the following disadvantages: first , the resistivity of the electrode is large, so the loss of electric energy is also large
Second, the electrode has poor flexibility and mechanical strength, it is easy to break after long-term folding, and its service life is short, so it is not easy to apply to flexible surface heat sources
Third, the density of the electrode is high, the weight is heavy, and it is inconvenient to use

Embodiment Construction

[0012] The surface heat source provided by the technical solution will be described in detail below in conjunction with the drawings and specific embodiments.

[0013] See figure 1 and figure 2 The embodiment of the technical solution provides a surface heat source 10, which includes a substrate 18, a reflective layer 17, a heating layer 16, a first electrode 12, a second electrode 14 and an insulating protection layer 15. The reflective layer 17 is disposed on the surface of the substrate 18. The heating layer 16 is disposed on the surface of the reflective layer 17. The first electrode 12 and the second electrode 14 are arranged on the surface of the heating layer 16 at intervals and are in electrical contact with the heating layer 16 to allow current to flow through the heating layer 16. The insulating protection layer 15 is disposed on the surface of the heating layer 16 and covers the first electrode 12 and the second electrode 14 to prevent the heating layer 16 from adsor...

Abstract

A plane heat source comprises a heating layer and at least two electrodes, wherein, the two electrodes are arranged at intervals and are electrically connected with the heating layer respectively; one of the two electrodes comprises a carbon nano tube structure.

Description

Technical field [0001] The invention relates to a surface heat source, in particular to a surface heat source based on carbon nanotubes. Background technique [0002] Heat sources play an important role in people's production, life, and scientific research. The surface heat source is a kind of heat source. Its characteristic is that the surface heat source has a flat structure. The object to be heated is placed above the flat structure to heat the object. Therefore, the surface heat source can heat all parts of the object to be heated at the same time. Wide, uniform heating and high efficiency. Surface heat sources have been successfully used in industrial fields, scientific research fields or life fields, such as electric heaters, infrared therapy devices, electric heaters, etc. [0003] The existing surface heat source generally includes a heating layer and at least two electrodes. The at least two electrodes are arranged on the surface of the heating layer and are electrically...
