Description

Technical Field

[0001] The utility model relates to the technical field of graphene, in particular to a graphene car coat rack. Background Art

[0002] Graphene is an allotrope of carbon. In graphene, in addition to the σ bonds through which carbon atoms are linked to form a hexagonal honeycomb-like layered structure with other carbon atoms, the pz orbitals perpendicular to the layer plane of each carbon atom can form a multi-atomic large π bond (similar to the benzene ring) that penetrates the entire layer, so it has excellent electrical and optical properties. In particular, graphene has very good thermal conductivity. The thermal conductivity of pure defect-free single-layer graphene can be as high as 5300 W / mK. Therefore, graphene has been more and more widely used in the field of thermal energy utilization.

[0003] For example, a Chinese patent with the publication number CN219947964U discloses a graphene heating seat. The heating seat includes a seat frame and a heating structure, and the heating structure is fixedly connected to the seat frame; the heating structure includes a graphene heating sheet and a packaging structure, and the packaging structure covers the graphene heating sheet. The graphene heating sheet is combined with the car seat frame to achieve uniform heating of the car seat; at the same time, a temperature reflection layer is pasted on the side of the graphene heating sheet away from the human body, which can achieve directional heating of the graphene heating sheet, thereby reducing heat loss and improving heating efficiency.

[0004] When the temperature is relatively low, generally the car air conditioner is turned on to blow hot air to heat the interior of the car. However, noise will be generated during the process of blowing hot air, which affects the safe driving of the driver and the comfort of the passengers; moreover, turning on the car air conditioner for a long time consumes a large amount of fuel, which is not conducive to energy conservation. Although the car coat rack is located in the car trunk, the coat rack is designed to store the clothes and hats of the passengers. When the temperature is relatively low, the clothes and hats can be heated to improve the comfort and happiness of the passengers; at the same time, there is a rear windshield above the coat rack, which is prone to fogging in low temperature or high humidity, affecting driving safety. According to the current search situation, there is no example of applying graphene to the current car coat rack. Therefore, a graphene car coat rack can be designed by using the high thermal conductivity of graphene. Summary of the Invention

Connection terminals are arranged between the electrode current-carrying strips and the silver electrode strips. The connection terminals penetrate the electrode current-carrying strips and are fixed on the silver electrode strips.

[0010] A polymer insulating film is thermally laminated on the graphene heating coating. The panel is on the upper layer of the polymer insulating film.

[0011] Preferably, a power cord is connected between the connection terminals. The power cord forms a wire harness in the middle of the silver electrode strip and is then connected to the vehicle wiring harness. A thermal protection switch is provided between the connection terminals and the power cord.

[0012] Preferably, the silver electrode strips on the graphene heating coating are in a "field" - shaped network, and the silver electrode strips cover the periphery of the edge of the graphene heating coating.

[0013] By adopting the above technical solution, after the silver electrode strips are electrified, due to the high thermal conductivity of graphene, the graphene heating coating can be quickly and uniformly heated and generate heat as a whole, improving the heat generation speed and efficiency.

[0014] Preferably, the heat dissipation holes on the bottom plate and the panel are evenly and densely arranged in a "field" shape.

[0015] By adopting the above technical solution, the heat generated by the graphene heating coating can be dissipated downward through the bottom plate towards the trunk and upward through the panel towards the rear windshield. It can quickly and evenly heat the rear windshield and the trunk.

[0016] Preferably, the composite board of the bottom plate and the panel is integrally molded by pressing with the embryo formed by the PET film, the graphene heating coating and the polymer insulating film.

[0017] By adopting the above technical solution, the integrally molded coat rack makes the embryo and the composite board fit more closely, with higher strength and stiffness.

[0018] Preferably, a number of connecting pieces or fixing pieces are arranged at corresponding positions on the bottom plate and the panel.
