Problems solved by technology

Due to the high internal resistance of these heating elements, a relatively high voltage is generally required. For example, two or more 3.8V lithium batteries are used in series, which is inconvenient.
There are also heating methods such as direct coiling of electric heating wires, resulting in uneven heating

Embodiment 2

[0071] This embodiment is basically the same as Embodiment 1, except that the internal electrodes and the bus bars are made of different materials. The transparent conductive material can be used as the inner electrode, and the metal material can be used as the bus bar; or different metal materials can be used as the inner electrode and the bus bar respectively; or the transparent conductive material can be used as the bus bar, and the metal material can be used as the inner electrode. In this embodiment, metal copper foil or silver paste is preferably used as the material of the bus bar, and graphene with at least 5 layers is used as the material of the internal electrodes. In this embodiment, it is more preferable to use metal platinum as the material of the bus bar and 10-layer graphene as the material of the internal electrodes. Single-layer graphene is used as the material of the transparent conductive layer (square resistance is 250Ω / □). The graphene internal electrode ...

Embodiment 3

[0075] This embodiment is basically the same as Embodiment 1, the difference lies in the specific design of the electrodes.

[0076] In order to ensure that the internal electrodes are arranged at different positions of the bus bar, the difference between the highest voltage and the lowest voltage does not exceed 10%. During the production of this embodiment, the number of intervals n generated by the internal electrodes, the longest length l of the internal electrodes, and the width W of the bus bar 1. The thickness H of the bus bar is measured and processed accurately, so that it conforms to the above formula (2).

[0077] This embodiment requires that the electrodes be arranged as follows: the length of the inner electrode is 108 mm, 15 intervals are generated in total, the width of the bus bar is 8 mm, and the thickness is 25 μm. After testing, the difference between the highest voltage and the lowest voltage at different positions of the bus bar is 0.2%.

Abstract

The invention discloses intelligent temperature control thermal underwear. A heating film layer is arranged to cover the whole or the part of the underwear. The underwear includes a temperature control module and a temperature sensor, which are used for controlling the heating temperature. A power supply is connected to the heating film layer through the temperature control module. The heating film layer can be formed by a low-voltage transparent electrothermal membrane or can be formed by multiple low-voltage transparent electrothermal membranes that are connected in series or in parallel through leads. The low-voltage transparent electrothermal membranes generate heat when low-voltage direct currents are sent to the low-voltage transparent electrothermal membranes. Through adoption of the temperature control module and the film type temperature sensor, the temperature of the thermal underwear can be controlled in a wireless and remote manner. The temperature also can be controlled by a mobile phone. The thermal underwear is more convenient to use, can be utilized in many ways, and is more user-friendly.

Description

technical field [0001] The invention relates to a thermal clothing heated by direct current, in particular to a controlled electric heating thermal clothing using a graphene heating film as a heating element. Background technique [0002] For the sake of health care or keeping warm, people often need to apply hot compresses to appropriate parts of the body surface. The heat source can be a heat-storing hot water bag, or a heat patch that uses chemical reactions to generate heat. In recent years, thermal underwear made by combining batteries and various types of electric heating films has appeared. For example: Chinese patent CN201020511754 has designed a kind of low-voltage electric heating thermal underwear. The thermal underwear designed includes clothing, conductive wire, temperature probe and interconnected lithium-ion battery and main control chip. It is heated by a portable low-voltage DC power supply and can be repeated It can be recharged and used for many times, an...
