preparation example Construction

[0031] see image 3 , the present invention provides a method for preparing the above-mentioned heating device 100, the method comprising the following steps:

[0032] Step 1: providing a first base body 102 and forming a first adhesive layer preform on a surface of the first base body 102 .

[0033] When the material of the first adhesive layer preform is a hot melt adhesive film, the first adhesive layer preform can be prepared by directly laying a hot melt adhesive film on the surface of the first base 102 . When the material of the first adhesive layer preform is hot melt adhesive powder, the hot melt adhesive powder can be sprinkled on the surface of the first substrate 102 to form a first adhesive layer preform. Optionally, an infrared reflection layer may be formed on a surface of the first substrate 102 by sputtering or other methods. The infrared reflection layer may be formed between the first base body 102 and the first adhesive layer preform or disposed on the su...

Abstract

The invention relates to a heating device and a manufacturing method thereof. The heating device comprises a first electrode, a second electrode and a heating element, wherein the first electrode and the second electrode are arranged at interval; the heating element comprises a first substrate, a second substrate, a first bonding layer, a second bonding layer and a carbon nanotube structure; the carbon nanotube structure is arranged between the first substrate and the second substrate and is combined with the first substrate and the second substrate respectively through the first bonding layer and the second bonding layer; and the carbon nanotube structure is electrically connected with the first electrode and the second electrode.

Description

technical field [0001] The invention relates to a heating device and a preparation method thereof. Background technique [0002] Existing heating devices generally include a heating element and at least two electrodes, and the at least two electrodes are arranged on the surface of the heating element and electrically connected with the heating element. When a voltage or current is applied to the heating element through the electrode, due to the high resistance of the heating element, the electric energy passed into the heating element is converted into heat energy and released from the heating element, thereby realizing heating. In the prior art, a heating element formed by braiding of metal wire or carbon fiber is usually used for electrothermal conversion. However, the strength of the metal wire is not high and it is easy to break, especially when it is bent or twisted at a certain angle, so its application is limited. In addition, the heat generated by the heating eleme...
