[0002] Hydrogen energy, as a sustainable, clean, and efficient energy source, has gradually entered the public eye. In the decades of hydrogen energy development, two-wheeled vehicles, as an important part of the modern transportation system, have attracted the attention of most hydrogen energy companies, and various hydrogen-powered two-wheeled vehicles have emerged.
[0003] Based on existing technology, most traditional hydrogen-powered two-wheelers on the market are air-cooled, meaning that the cooling of the hydrogen energy device relies solely on the rotation of a fan inside the vehicle. The power and lifespan of air-cooled hydrogen-powered two-wheelers are significantly lower than those of water-cooled hydrogen-powered two-wheelers due to factors such as the materials and assembly methods of the air-cooled hydrogen energy device. However, water-cooled hydrogen-powered two-wheelers cannot be widely promoted due to their large hydrogen requirements and difficulties in cooling. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a canvas-type heat exchange device for solid-state hydrogen storage two-wheeled vehicles. This solves the pain points of water-cooled two-wheeled vehicles, such as high hydrogen demand and difficulty in cooling, and promotes the further commercialization, scaling up, and marketization of water-cooled hydrogen-powered two-wheeled vehicles, thus accelerating the development of the hydrogen energy industry from multiple perspectives.
[0005] This utility model discloses a canvas-type heat exchange device for a two-wheeled vehicle with solid hydrogen storage, achieved through the following specific technical means:

[0007] Furthermore, multiple sets of heat exchange sleeves may be provided; the tops of the heat exchange sleeves are connected by pipes; and a vent is provided on the left side of the top of the heat exchange sleeve.
[0008] Furthermore, the cover plate is divided into upper and lower groups; the cover plate is provided with a placement ring; the upper and lower groups of cover plates are connected by a connecting post; the upper and lower groups of cover plates are fixedly connected by a back plate; the bottom of the back plate is connected to the placement plate.
[0009] Furthermore, a liquid level detector is installed on the expansion tank; the water pump output port is connected to the radiator through an inlet pipe; a deionizer is installed at the radiator outlet; and the deionizer is connected to the bipolar plate through an inlet pipe.

[0011] Furthermore, the bipolar plate is provided with flow channels.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this device, by setting up a heat exchange sleeve and a canvas water jacket, the hydrogen released from the hydrogen storage tank enables the fuel cell to start. The fuel cell generates a large amount of heat during operation. As the water pump rotates, the hot water generated by the fuel cell flows to the deionizer, which removes any ions that may be present in the water generated by the fuel cell. Then, it flows to the radiator to help the hydrogen storage tank dissipate excess heat. The hot water then flows to the expansion tank, and finally, it flows to the canvas water jacket. The heat at the canvas water jacket causes the hydrogen storage tank to release more hydrogen. When the hydrogen storage tank releases hydrogen, it absorbs the heat inside the canvas water jacket, thereby cooling the coolant inside the canvas water jacket. The cooled coolant then flows back to the fuel cell under the action of the water pump, further reducing the temperature of the fuel cell. This also promotes the release of hydrogen from the solid hydrogen storage tank, improving the overall efficiency of the water-cooled hydrogen vehicle and contributing to the development of the hydrogen energy industry.

[0030] The specific usage and function of this embodiment are as follows:
[0031] In this invention, when using the device, the vent 101 is opened, coolant is added to the water-cooled hydrogen fuel cell vehicle, the water pump 8 is turned on to fill the canvas water jacket 104 with coolant, and the fuel cell 12 is started. The hydrogen released from the hydrogen storage tank 3 enables the fuel cell 12 to start. The fuel cell 12 generates a large amount of heat during operation.

The deionizer 10 removes any ions that may be present in the water generated by the fuel cell 12. Then it flows to the radiator 9. When the water temperature measured by the temperature detector B1031 is greater than 50°C, the radiator 9 starts to assist the hydrogen storage tank 3 in dissipating excess heat. If the excess heat cannot be completely dissipated, the temperature detector A1021 measures the fuel cell temperature. When the outlet water temperature exceeds 70℃, the high-temperature protection mechanism will be activated, forcibly shutting down the fuel cell 12. Next, the hot water will pass through the water pump 8 and flow to the expansion tank 6.

Finally, the hot water flows to the canvas water jacket 104 under the action of the water pump 8. The heat at the canvas water jacket 104 will cause the hydrogen storage tank 3 to release more hydrogen, solving the problem of high hydrogen demand of the fuel cell 12. At the same time, the hydrogen storage tank 3 absorbs the heat inside the canvas water jacket 104 when releasing hydrogen, thereby cooling the coolant inside the canvas water jacket 104. The cooled coolant will then flow back to the fuel cell 12 under the action of the water pump 8, thus achieving the purpose of cooling the fuel cell 12.
