Problems solved by technology

[0003] At present, there are only sporadic reports on metal nanowire film heaters. The heaters in the reports all use regular rectangular heating surfaces; however, there are very few regular rectangular heating surfaces in practical applications, and it is urgent to develop irregular non-rectangular surfaces suitable for various environments. Heaters to meet the needs of practical applications. At present, there is no report or patent protection for such heaters.

Embodiment 1

[0028] This embodiment provides a circular surface heater based on a silver nanowire transparent conductive film that can be used on the porthole of a spacecraft and a preparation method thereof. The steps of the preparation method are as follows:

[0029] (1) Substrate: A circular polyethylene terephthalate substrate with a thickness of 100 μm and a diameter of 20 cm was cut for use.

[0030] (2) Conductive functional film: On the substrate, use an automatic scraper coating device to apply an ink with a concentration of 1mg / mL prepared by silver nanowires with a diameter of 100nm and a length of 100μm, and scrape once to form a film, and then dry it in a drying oven at 60°C for 5 minutes .

[0031] (3) Performance adjustment layer: soak the dried film in 5wt% tin chloride aqueous solution for 10 seconds, then soak it in deionized water for 10 seconds, and then dry it in a drying oven at 60° C. for 5 minutes.

[0032] (4) Conductive electrode: Use a mask to cover the film, le...

Embodiment 2

[0036] This embodiment provides a trapezoidal surface heater based on a silver nanowire transparent conductive film and a preparation method thereof that can be used on an automobile windshield. The steps are the same as in Example 1 except for the shape of the surface heater and the conductive electrodes, specifically :

[0037] The base is a trapezoid with a large arc surface whose upper and lower sides are 100cm, 135cm, and 60cm high, such as Figure 4 (a) shown. Using the largest inscribed rectangle of a trapezoid with a large arc surface, two schemes of conductive electrodes are obtained. Such as Figure 4 As shown in (b), based on the upper and lower sides of the rectangle with the largest area inscribed in the trapezoid, the edges of the trapezoid of the large arc surface enclosed by these two sides coincide with the upper and lower sides of the rectangle, that is, the rectangle’s The upper and lower sides are the distribution positions of a pair of metal electrodes....

Embodiment 3

[0039] This embodiment provides a rectangular heater with large rounded corners and a preparation method thereof that can be used on aircraft portholes and is based on a silver nanowire transparent conductive film. The steps are the same as in Embodiment 1 except for the shape of the surface heater and the design of the conductive electrodes, specifically :

[0040] The base is a 40cm×29cm rounded rectangle, and the length and width of the rounded corners span 10cm, such as Figure 5 (a) shown. Using the largest inscribed rectangle of a rounded rectangle, two schemes of conductive electrodes are obtained. Such as Figure 5 As shown in (b), based on the upper and lower sides of the largest area inscribed in the rounded rectangle, the edges of the rounded rectangle enclosed by these two sides coincide with the upper and lower sides of the rectangle, that is, the The upper and lower sides are the distribution positions of a pair of metal electrodes. Such as Figure 5 As show...

Abstract

The invention discloses a non-rectangular surface heater based on a metal nanowire film; the heater comprises a substrate, a conductive function film, a performance adjusting layer and conductive electrodes; the conductive function film is a conductive cannel formed by metal nanowire grids positioned on the substrate; the conductive electrodes comprise two linear metal electrodes; the two linear metal electrodes are respectively arranged on edges of the non-rectangular surface heater, wherein said edges are respectively enveloped by opposite edges of the maximum area rectangular inscribed by the non-rectangular surface heater. The non-rectangular surface heater based on the metal nanowire film can heat non regular surfaces, and the formed heating area is even and effective.

Description

technical field [0001] The invention belongs to the technical field of intelligent temperature control, and relates to the design and application of a heater under flexible application requirements such as irregular shapes, curved surfaces, bending, and vibrations, and also relates to the design and application of a heater under the application requirements of transparent heating. Background technique [0002] Thermal control devices are playing an increasingly important role in the civilian and military fields, such as window defogging and defrosting applied to car windshields, spacecraft portholes, and fighter jet canopies, etc., and electronic cigarette heating cores and infrared decoys. Irregular surface temperature control, etc.; and with the rapid development of science and technology in recent years, the pursuit of intelligence in both military and civilian fields has been increasing, such as one-key quick window defogging. Realizing these intelligent requirements req...
