[0024] In order to make the technical solutions and advantages in the embodiments of the present application more clear and apparent, the exemplary embodiments of the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
[0025] In the embodiments of the present application, a rail vehicle heating device is provided, which comprises: Figure 1 and Figure 3As shown, it comprises: an upper heat-conducting protective layer 1, a heating layer 2, an intermediate support layer 3, a sandwich material layer 4, a lower protective layer 5 and an edge sealing 6, the upper heat-conducting protective layer 1, the heating layer 2, the intermediate support layer 3, the sandwich material layer 4 and the lower protective layer 5 are all plate-shaped structures and are sequentially stacked and tightly connected, and the edge sealing 6 is arranged at the periphery of the upper heat-conducting protective layer 1, the heating layer 2, the intermediate support layer 3, the sandwich material layer 4 and the lower protective layer 5. The heat emitted by the heating layer 2 can be absorbed by the upper heat-conducting protective layer 1 and released into the surrounding air, the heat is rapidly transferred by conduction, and the uniformity of external heat radiation can be effectively improved. Moreover, the heating layer of the rail vehicle heating device is in a sheet-shaped structure, the heating area is large, and the risk of burns caused by concentrated heating at a certain place is avoided. Therefore, when used for rail vehicles, the device can quickly and uniformly supply heat to the vehicle compartment, meeting the comfort and safety requirements for passengers.
[0026] In the embodiment of the present application, the edge sealing 6 comprises a support part 61, an upper edge sealing part 62 and a lower edge sealing part 63. The support part 61 is located outside the sandwich material layer 4 and between the intermediate support layer 3 and the lower protective layer 5. The upper surface of the support part 61 is bonded to the intermediate support layer 3 through a glue layer 7, and the lower surface of the support part 61 is bonded to the lower protective layer 5. The thickness of the support part 61 is the same as that of the sandwich material layer 4. The upper edge sealing part 61 is located outside the upper heat-conducting protective layer 1, the heating layer 2 and the intermediate support layer 3, and is bonded to the upper heat-conducting protective layer 1 and the intermediate support layer 3, respectively. The upper surface of the upper edge sealing part 61 is flush with the upper surface of the upper heat-conducting protective layer 1. The upper heat-conducting protective layer 1 plays a role in protecting the lower heating layer 2 and transferring the heat of the heating layer 2 to the air above it. It is only bonded to the upper edge sealing part 61 through the glue layer 7 along the side edge, which ensures its heat conduction and protection function, and also facilitates disassembly and maintenance when the heating layer 2 fails. The upper edge sealing part 61 can effectively protect the edges of the upper heat-conducting protective layer 1, the heating layer 2 and the intermediate support layer 3, avoiding deformation of the upper heat-conducting protective layer 1 and the intermediate support layer 3 and damage to the heating layer 2 caused by bumps. The lower edge sealing part 62 is located outside the lower protective layer 5 and is bonded to the lower protective layer 5. The lower surface of the lower edge sealing part 62 is flush with the lower surface of the lower protective layer 5. The intermediate support layer 3 and the sandwich material layer 4 are bonded through the glue layer 7, and the sandwich material layer 4 and the lower protective layer 5 are also bonded through the glue layer 7. Therefore, the edge sealing in the embodiment of the present application plays a protective role for the other layers of the rail vehicle heating device, and also serves as a "skeleton" to provide support.
[0027] In the embodiment of the present application, the heating source of the heating layer 2 is a far-infrared carbon fiber heating film. The far-infrared carbon fiber heating film generates heat by utilizing the thermal motion phenomenon of carbon atoms vibrating and rubbing against each other. The heating layer transfers heat to space in the form of thermal radiation, with an electric heating conversion efficiency of 99%, significant energy-saving and emission-reducing effect, and compliance with national green energy-related laws and regulations.
[0028] In the embodiment of the present application, the heat generating layer 2 further comprises a temperature sensor. The heat generating layer 2 is made of a far-infrared carbon fiber heating film, and the temperature sensor is arranged between the far-infrared carbon fiber heating film and the upper heat-conducting protective layer 1, and is used to detect the heat emitted by the far-infrared carbon fiber heating film. When the rail vehicle heating device is installed on the rail vehicle, the temperature information detected by the temperature sensor of the air conditioning system of the vehicle can be obtained to realize automatic control of the temperature of the rail vehicle heating device and provide comfort in the vehicle compartment.
[0029] In the embodiment of the present application, the upper heat-conducting protective layer 1, the middle supporting layer 3 and the lower protective layer 5 are all made of aluminum alloy material, which is light in weight and reliable in strength, and is conducive to reducing the weight of the whole vehicle and meeting the light weight requirement of the vehicle.
[0030] In the embodiment of the present application, the thickness of the upper heat-conducting protective layer 1 is greater than the thickness of the lower protective layer 5, and the thickness of the lower protective layer 5 is greater than the thickness of the middle supporting layer 3. The thicknesses of the upper heat-conducting protective layer 1, the middle supporting layer 3 and the lower protective layer 5 can be adjusted according to factors such as passenger carrying capacity. The main function of the upper heat-conducting protective layer 1 is to protect the heat generating layer 2 and make the heating effect more uniform. Since it is in the outermost layer, it is more likely to be damaged or impacted by external factors, and therefore its thickness is relatively thick. The main function of the lower protective layer 5 is to provide external protection, but it is less likely to be damaged or impacted by external factors than the upper heat-conducting protective layer 1, and therefore its thickness can be slightly smaller than that of the upper heat-conducting protective layer 1. The middle supporting layer 3 can not only support the heat generating layer and the upper heat-conducting protective layer above it, but also provide a flat surface for the heat generating layer, thereby providing a supporting platform for the heat generating layer to avoid bending of the heat generating layer, especially to reduce damage to the heat generating layer caused by misalignment in the up-down direction due to extrusion of the layers. At the same time, the three-layer plate structure made of aluminum alloy material formed by the upper heat-conducting protective layer 1, the middle supporting layer 3 and the lower protective layer 5 further improves the support of the middle supporting layer 3 below the sandwich material layer 4 in the rail vehicle heating device, and therefore the thickness of the middle supporting layer 3 can be smaller than that of the lower protective layer 5.
[0031] In the embodiment of the present application, the sandwich material layer 4 is made of PET material. The edge seal 6 is made of aluminum alloy profile, and the sandwich material layer 4 can be extruded and assembled between the edge seals 6 during assembly. The cross-sectional structure of the aluminum alloy profile of the edge seal 6 can be adjusted according to actual needs such as weight reduction and thickness. Whether the sandwich material layer is made of PET material or the edge seal is made of aluminum alloy profile, it is conducive to reducing the weight of the whole vehicle and meeting the light weight requirement of the vehicle.
[0032] In the embodiment of the present application, as shown in FIG. 1, the rail vehicle heating device comprises a heat generating layer 2, an upper heat-conducting protective layer 1, a middle supporting layer 3, a lower protective layer 5, a sandwich material layer 4 and an edge seal 6. Figure 2As shown, the outer side of the edge 6 has a connecting part 64 for fixing the rail vehicle heating device to a predetermined position or connecting two adjacent rail vehicle heating devices together. The connecting part 64 can be a protrusion extending outward, and the protrusions on the opposite sides of the rail vehicle heating device are respectively arranged at the upper part and the lower part, so that when two adjacent rail vehicle heating devices are connected, the connecting parts can be engaged with each other in a top-to-bottom manner. Of course, in other embodiments, the connecting part 64 can have other structures that can be matched with each other, and the present application does not limit this. For example, protrusions are arranged at the upper part and the lower part on one side of the rail vehicle heating device, and the upper and lower protrusions are arranged at intervals. A protrusion is arranged at the middle part on the opposite side of the rail vehicle heating device, and the position of the middle protrusion corresponds to the interval between the upper and lower protrusions.
