Carbon fiber energy-saving heating module and underfloor heating system

Abstract

The invention discloses a carbon fiber energy-saving heating module and an underfloor heating system. The carbon fiber energy-saving heating module includes a heat preservation plate, a heat conduction plate and a heating wire. The heat conduction plate is disposed above the heat preservation plate. The heating wire is routed on the heat conduction plate. The heating wire includes at least two carbon fire heating cell lines which are in a bundle shape. Each carbon fiber heating cell line includes a plurality of carbon fiber filaments and insulating layers which are configured in a bundle shape. The plurality of carbon fiber filaments are arranged inside the insulating layers. Different carbon fiber heating cell lines have identical or different number of carbon fiber filaments. According to the invention, the heating wire in the carbon energy-saving heating module uses two or more than two carbon fiber heating cell lines which can laminate heat so as to reach a required temperature. Single carbon fiber heating cell line has reduced number of carbon fiber filaments, lower heating power and reduced electricity consumption.

Description

technical field [0001] The invention relates to the field of carbon fiber, in particular to a carbon fiber energy-saving heating module and a floor heating system. Background technique [0002] Carbon fiber is a new material with excellent mechanical properties. Heating cables of various specifications are made of carbon fiber. It has the dual advantages and characteristics of carbon elements and fibers. It has good heat conversion rate, fast heat generation, stable resistance value and uniform distribution. And so on, it is widely used in various fields. Its specific gravity is less than 1 / 4 of that of steel, but its tensile strength is 7-9 times that of steel, and its tensile modulus of elasticity is also higher than that of steel. Compared with metal cables, it has a great advantage and is the best of traditional floor heating cables. Good substitute product.

AI Technical Summary

Problems solved by technology

[0003] Carbon fiber cables currently on the market are generally formed by twisting a plurality of carbon fiber heating wires to form a carbon fiber heating element 5, see Image 6 , and then formed by wrapping an insulating sheath 6 on the outer periphery of the above-mentioned carbon fiber heating element 5, the carbon fiber cable formed in this way has at least the following two disadvantages: first, the single-strand carbon fiber heating element must meet the required emission heat, it is necessary to twist a large number of carbon fiber heating wires, the resistance decreases, the current increases, and the actual heating power increases, that is, the power consumption is large; second, the heat resistance of the outer sheath of the existing carbon fiber cable is low , can not meet the requirements of some high-temperature application environments

[0004] On the other hand, in the prior art, the heating wires of the heating floor are generally laid on the floor body, and the wiring groove is opened on the floor body, which not only complicates the slotting process, but also easily causes defects such as floor delamination and cracking.

In the prior art, heating wires are also laid in cement, but this is easy to cause slow heating and high energy consumption
