Abstract

The present invention relates to an electric heating mat using a hot wire made of a carbon fiber filament. A polyester yarn is twisted in a screw shape on the hot wire to cover the hot wire, and the hot wire is double sheathed such that a heat amount of the carbon fiber filament hot wire is sufficiently secured, and a support strength of the hot wire is more reinforced such that disconnection of the hot wire is not occurring, thereby maintaining safety of the hot wire. The filament hot wire is connectively distributed in parallel to separate into two or more heating portions to form a heating plate, an efficiency in temperature control can be maximized such that local overheating generated due to restriction of heat emission due to a weight or a load can be prevented. The carbon fiber filament hot wire is composed of a heating wire and a general power wire.

Description

Thermal mats using carbon fiber heating wire {omitted}

In the present invention, a filament hot wire made of carbon fiber is twisted with polyester yarn to prevent stretching and contraction, so that a heating value of a heating wire is sufficiently secured, and the polyester surface is first coated with a flame retardant PVC soft member, The carbon fiber heating wire constructed by extruding the entire secondary coated flame retardant PVC soft resin with the earth wire of the enamel coated copper wire inserted into the aluminum foil, thereby canceling the electric field, In addition to being economical because the heating element is generally warm and power consumption is low, since the carbon fiber heating wire is twisted to polyester yarn, a sufficient calorific value is supplemented by insufficient heating amount of the carbon fiber by the polyester yarn to compensate the tensile strength of the carbon fiber, Configured to prevent fiber disconnection The present invention relates to a thermal electric mat using a carbon fiber heating wire

Since most of the heating wires of ordinary mats use copper (copper wires) or copper alloy wires, they are broken due to continuous heat opening and heating, and hot wires are formed by a series of wires, which are formed into a thin nonwoven fabric or a similar sheet, And the conventional carbon fiber heating cable has a problem that sufficient heating value can not be secured due to the heating limit of the carbon fiber,

The filament heating wire is twisted with polyester and then subjected to a double coating process so as to maintain safety. The carbon fiber filament heating wire is connected in parallel to form a heating plate by separating into two or more heating units, The object of the present invention is to provide a thermal electric mat using a carbon fiber heating cable which can be safely used by connecting a heat sensor and a bimetal which can control heat emission above a predetermined temperature to a specific region of a plate, It is

In order to accomplish the above object, the present invention provides a carbon fiber heating cable formed by twisting a carbon fiber heating wire made of a plurality of filaments with a polyester yarn and then performing a double coating treatment to stabilize the heating wire. And to prevent the local overheating caused by the restriction of the heat emission due to the load or the load of the heat ray by maximizing the efficiency of the temperature control

In the present invention, a heating yarn in which a carbon fiber heating wire is formed by a filament is twisted with polyester yarn, and a double coating is performed on the twisted yarn to secure safety, sufficient heat generation amount of the heating wire is secured and sufficient supporting strength is secured in the heating wire, And no disconnection occurs at all
