Electric-leakage-preventing carbon fiber heating plate

Abstract

The invention relates to an electric-leakage-preventing carbon fiber heating plate which comprises a carbon fiber conducting layer and two insulation reinforcing layers, wherein two copper strips externally connected with a power supply are arranged on the carbon fiber conducting layer; the carbon fiber conducting layer and the copper strips are pressed between the two insulation reinforcing layers; a metal layer connected with a ground / zero circuit is arranged outside any one of the two insulation reinforcing layers; or the two metal layers which are communicated with the ground / zero circuit are respectively arranged outside the two insulation reinforcing layers. The upper and the lower metal protecting layers are clamped and are connected with the ground / zero circuit, so that the electric leakage in a heating process is prevented. The upper and the lower metal protecting layers are matched and sewed with the copper strips through a sewing line; and the carbon fiber conducting layer and the copper strips are pressed, so that the copper strips and the carbon fiber conducting layer are heated safely and stably. The carbon fiber heating plate provided by the invention has the advantages of being simple in structure, convenient to manufacture, safe to use and long in service life.

Description

technical field [0001] The invention relates to a heating plate, in particular to an anti-leakage carbon fiber heating plate for ground and wall heating. Background technique [0002] With the advancement of heating technology, geothermal heating is now being vigorously promoted in northern my country. According to statistics, by the end of 2011, large and medium-sized cities in northern my country have begun to promote geothermal heating on a large scale. Floor heating is floor radiant heating, which uses the entire floor as a radiator, heats the entire floor evenly through the heat medium in the floor radiation layer, and uses the heat storage of the floor itself and the law of upward radiation of heat to conduct from bottom to top to achieve heating. Purpose. Ground radiation heating is mainly divided into water floor heating and electric floor heating according to different heating methods. The installation cost of water floor heating is high in the early stage, and th...

Problems solved by technology

Existing carbon fiber electric heaters, such as the carbon fiber painted heating plate disclosed in the patent No. 201110060098.6, are bonded with copper strip electrodes on both sides of the carbon fiber conductor. The strip electrode and the carbon fiber conductor are easy to fall off, the connection is not reliable, the use is stable, and the safety performance is low; for example, the far-infrared electric heating decorative panel disclosed in the patent No. 200320107576. The crimping of carbon fiber paper is easy to be falsely connected, causing flashover, and there is leakage current, which is easy to trip during use, affecting normal use and use safety
