Embodiment 1

[0044] Example 1: Heating Pad with Heating Elements

[0045] specifically, figure 1 and figure 2 Shown is an internal view of a heating pad 10 with a metal-free heating element, in which a metal-free heating element 20 made of multi-walled carbon nanotubes (MWCNT), PLA, PBT and PBAT is arranged in parallel, and each heating element 20 is connected by connecting wire 70, and the connecting wire 70 can be figure 1 The heating wire 73 shown can also be figure 2 The first electric wire 71 is shown; when it is a heating wire 73 , it is finally connected to the first electric wire 71 .

[0046] The connection and image 3 The contents together constitute the insertion injection junction 80.

[0047]In addition, two or more temperature sensors 40 are preferably placed between the heating elements 20 arranged in parallel in the heating pad 10 to sense the temperature of the heating pad 10 during use, and one or more temperature fuses 30 are provided to cut off the current when ...

Embodiment 2

[0052] Embodiment 2: performance test

[0053] The heating wire of the heating element 20 described in this application has a small heat capacity, does not accumulate heat, has the characteristics of releasing more than 90% of heat to the outside, is softer and warmer than the metal heating element, and releases more heat energy, and has the ability to conduct heat evenly inside the heating pad. Advantages of heat.

[0054] The heating element of the present application can replace wires and heating elements of metal series (copper, aluminum), has the effect of reducing carbon dioxide and energy consumption, and can be widely used in IT household appliances, daily necessities, drones, electric vehicles, military use, Robots, sensors, industrial supplies, residential heating and many other fields.

[0055] Compared with metals, carbon nanotubes (Carbon Nano Tube, CNT) can shield and absorb electromagnetic waves, release far-infrared rays, antibacterial, anti-corrosion, anti-ox...

Abstract

The application relates to a metal-free heating element, which belongs to the field of heating devices. The heating element is composed of multi-walled carbon nanotubes (MWCNT), poly lactic acid (PLA), poly butylene terephthalate (PBT), and polybutylene adipate-co-terephthalate (PBAT). The application further provides a heating pad with the heating element and an application of the heating element.

Description

technical field [0001] The application relates to a metal-free heating element and a heating pad, belonging to the field of heating devices. Background technique [0002] Heating elements are often used in heating pads, which are heating appliances widely used by ordinary families in winter. Heating pads usually use metal wires as heating elements to generate heat, directly using household AC power. A heating pad that uses metal wire as a heating element and directly uses alternating current has low energy efficiency, and there is a risk of leakage due to direct use of alternating current, and electromagnetic radiation will also cause damage to the human body. Therefore, there is a rising demand for heating pads using heating elements that can improve energy efficiency, reduce electromagnetic radiation, and reduce the risk of electric leakage. [0003] In order to meet the above demands, various technologies using carbon fibers or carbon nanotubes (Carbon Nanotube, CNT) as...
