Description

Technical Field

[0001] The utility model relates to the technical field of graphene film nano heating films, and more specifically, to a dry - burning prevention device for a graphene film and a nano - coating heating body. Background Technique

[0002] Graphene films and nano - coating heating films mainly rely on screen printing or high - temperature spraying processes. In this process, patterns are formed on a screen plate, and a squeegee is used to press ink or slurry through the screen plate, thereby printing the required heating material layer on a substrate. These material layers undergo subsequent treatments such as drying and sintering to form heating films with stable electrical and mechanical properties.

[0003] Currently, in the preparation process of graphene film nano - heating films, it is usually necessary to use screen - printing equipment to print graphene nano - materials on substrates such as microcrystalline glass and quartz ceramics and form corresponding heating wires. To ensure safety in use, the film layer itself needs to limit the maximum temperature. However, the heating and temperature - rising speed of this film layer is usually relatively fast. The prior art controls dry - burning prevention by means of an externally connected temperature - control probe, an externally connected induction spring device, or by drilling holes in the carrier of the heating film to install an externally connected liquid - level probe, etc. Since these are set outside the film layer, the reaction speed is slow, and it is easy to cause the phenomenon of dry - burning of the film layer. In view of this, we propose a dry - burning prevention device for a graphene film and a nano - coating heating body. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a dry - burning prevention device for a graphene film and a nano - coating heating body, so as to solve the technical problem that the current existing temperature - control structure is set outside the film layer, resulting in a slow reaction speed and easy to cause dry - burning of the film layer.

The induction probes are externally connected to an electronic processor, the electronic processor is externally connected to a power controller, and the power controller is connected to the circuit components to form a closed loop.

[0007] The utility model designs a temperature measuring component, and sets the induction probe on the carrier by means of screen printing, that is, the circuit component and the induction probe are fixed on the carrier at one time by screen printing. The circuit component and the induction probe are integrally arranged, so that the induction probe is integrated on the carrier, reducing the structure and process of installing an external probe. It has the characteristics of compact structure, fast and stable induction, which is beneficial to quickly judge the load state of the carrier and quickly control the heating power of the film layer, so as to achieve the effect of anti-dry burning.

[0008] Preferably, the circuit component includes a heating circuit layer screen-printed on the carrier, and the heating circuit layer is sintered into a film-like heating structure on the carrier by sintering a nano-coating applied by screen printing or spraying.

[0009] Preferably, the temperature measuring component includes an induction detection circuit layer screen-printed on the carrier. One end of the induction detection circuit layer is connected with a connection probe, and a plurality of temperature measuring circuit layers for monitoring and controlling the heating temperature of the heating circuit layer are distributed on the induction detection circuit layer. A plurality of parallel branch points are arranged on the induction detection circuit layer. The temperature measuring circuit layer includes a branch circuit layer extending and connecting to the parallel branch points. The branch circuit layer is arranged between the serpentine heating structures of the heating circuit layer, and a circuit joint is arranged at the end of the branch circuit layer.

[0010] Preferably, the carrier includes a ceramic-based membrane, and both the circuit component and the temperature measuring component are screen-printed on the ceramic-based membrane.

The polyimide insulating layer is fixedly connected to the electromagnetic shielding adhesive layer.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model designs a temperature measuring component, and sets the induction probe on the carrier by means of screen printing, that is, the circuit component and the induction probe are fixed on the carrier at one time by screen printing. The circuit component and the induction probe are integrally arranged, so that the induction probe is integrated on the carrier, reducing the structure and process of installing an external probe. It has the characteristics of compact structure, fast and stable induction, which is beneficial to quickly judge the load state of the carrier and quickly control the heating power of the film layer, so as to achieve the effect of anti-dry burning, and solves the problem that the existing temperature control structure is arranged outside the film layer, resulting in a slow reaction speed and easy dry burning of the film layer.

[0015] 2. The present utility model also designs the heating circuit layer into a serpentine structure, so that the carrier has a larger heating area and better heating effect.
