Description

Technical Field

[0001] The present invention belongs to the technical field of graphene, and particularly relates to a graphene liquid heating tube and a heating pad containing the graphene liquid heating tube. Background Art

[0002] At present, the structures of devices in the heating fields of civil household and industrial applications are relatively complex, and there are a series of problems such as high energy consumption, potential safety hazards, high cost-effectiveness, complex installation, complex temperature control modules, and relatively high costs. In order to alleviate the environmental and energy pressures, the state has introduced the policy of replacing coal with electricity for energy conservation, emission reduction, low-carbon and environmental protection.

[0003] With the rapid development of graphene technology, the situation of high cost of graphene has gradually begun to ease, and more and more enterprises and institutions have launched their own graphene products. Among them, graphene heating technology has developed rapidly recently, and patents around graphene heating technology have emerged in an endless stream. For example, the authorized invention "An electric water heating tube based on graphene technology", with the authorized announcement number CN206113286U, constructs an electric water heating tube with a hollow structure of two layers of graphene membranes arranged in the interlayer space between the inner and outer tubes, and heats the fluid in the inner tube through the hollow interlayer. The invention patent "A graphene-based interlayer heating tube", with the publication number CN109890095A, discloses a production process of a graphene-based interlayer heating tube.

[0004] However, the graphene liquid heating tubes disclosed in these several patents have not solved a problem: the developed graphene liquid heating tubes are straight, without flexibility, cannot be bent, and cannot be used for coiled tubes, etc. This is an urgently needed problem to be solved in practical applications, especially for water heating mattresses and floor heating, which require a graphene liquid heating tube to be coiled multiple times. The flexibility of the graphene heating tubes in the prior art cannot meet the actual application requirements. Summary of the Invention

[0005] In order to solve the problem that the graphene liquid heating tube cannot be bent and coiled, the present invention decides to develop a graphene liquid heating tube and a heating pad containing the graphene liquid heating tube.

[0006] A graphene liquid heating tube includes a plurality of graphene liquid heating tube units. Each graphene liquid heating tube unit includes an outer tube, a graphene heating layer, and an inner tube. The three layers of the outer tube, the graphene heating layer, and the inner tube are closely attached in sequence. The graphene heating layer includes graphene heating wires, heat-conducting fibers, and conductive copper wires. The graphene heating wires are combined with the heat-conducting fibers and are segmented and woven together with the conductive copper wires through a cylindrical weaving process. Conductive copper wires are respectively arranged at both ends of each graphene liquid heating tube unit.

[0007] Further, the quantity ratio of the graphene heating wires to the heat-conducting fibers is 1:1 - 1:10.

[0008] Further, the number ratio of the graphene heating wire to the heat-conducting fiber is 1:1, and the graphene heating wire and the heat-conducting fiber are alternately distributed in sequence.

[0009] Further, the material of the outer tube is a TPU tube or a PEX tube, and the TPU tube or the PEX tube is a bendable flexible tube.

[0010] Further, the material of the inner tube is a TPU tube or a PEX tube, and the TPU tube or the PEX tube is a bendable flexible tube.

[0011] Further, the length of each graphene liquid heating tube unit is 1 m, and the graphene liquid heating tube can be cut to the required length according to needs.

[0012] A heating pad containing a graphene liquid heating tube includes a graphene liquid heating tube, a controller, a temperature sensor, and a power plug. The controller is respectively connected to the conductive copper wires at both ends of the graphene liquid heating tube. The graphene liquid heating tube is bent and coiled into a plurality of connected S-shaped tubes. The temperature sensor is installed at the middle position of the graphene liquid heating tube. The controller is also respectively connected to the temperature sensor and the power plug.

[0013] Further, it further includes a water pipe positioning cotton, and the graphene liquid heating tube is installed in the groove of the water pipe positioning cotton.

[0014] The beneficial effects obtained by the present invention are as follows:

[0015] 1. The graphene liquid heating tube has a fast heating rate. The power supply is connected to the conductive copper wire in the graphene liquid heating tube, and the power supply can directly heat the liquid in the graphene liquid heating tube.

[0016] 2. The graphene liquid heating tube has a high electric energy utilization efficiency. Compared with the traditional thermal resistance heating, the effective utilization rate of electric energy can reach more than 95%.

[0017] 3. The graphene liquid heating tube has better flexibility, can meet the requirements of bending and coiling the tube, and can be cut to the required length according to needs. The present invention is applied to water heating mattresses and floor heating, with a large demand and strong practicability.

[0018] 4. For the heating pad containing a graphene liquid heating tube, the power supply directly heats the water in the graphene liquid heating tube, without the need for a separate heating device, nor the need for a graphene flexible electric heating film and a separate water pipe. The structure is simple and the energy utilization rate is high. Description of the Drawings
