Description

Technical Field

[0001] This utility model relates to the field of hydrogen-powered electric bicycle technology, and in particular to a hydrogen intake and circulation mode device for a hydrogen-powered electric bicycle. Background Technology

[0002] In the field of hydrogen-powered bicycles, the hydrogen fuel cell is a core component, and its performance is closely related to the hydrogen intake mode. Most existing hydrogen-powered bicycles use a fixed direct intake mode, where outside air is directly introduced into the hydrogen fuel cell reactor. When the bicycle is being ridden, the temperature of the hydrogen cylinder drops. Over time, this reduces the efficiency of the hydrogen reactor, resulting in low hydrogen utilization, unstable bicycle performance, and even affecting the lifespan of the hydrogen reactor. Therefore, traditional bicycles typically have heating wires installed inside the downpipe to heat and insulate the hydrogen cylinder. However, the structure of the heating wires not only occupies space in the downpipe, increasing the overall size, but also increases energy consumption, which is detrimental to the battery's long-term operation. Furthermore, heat dissipation for the hydrogen reactor generally relies solely on a cooling fan, requiring increased fan speed to improve cooling efficiency, and the direct expulsion of heat is energy-intensive. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hydrogen intake circulation mode device for hydrogen-powered electric bicycles. It can recycle the heat discharged from the hydrogen reactor, maintain the temperature of the hydrogen cylinder during operation, and ensure the overall performance of the electric bicycle.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A hydrogen intake and recirculation mode device for a hydrogen-powered electric vehicle includes a lower pipe and an electric stack box connected to the rear end of the lower pipe.

[0006] The fuel cell stack box contains a hydrogen reactor. A cooling fan is installed on the side of the hydrogen reactor near the lower tube. The lower tube is divided into an upper storage chamber and a lower ventilation channel. A hydrogen storage tank for supplying gas to the hydrogen reactor is placed in the storage chamber.

[0007] During the reaction, the hydrogen reactor dissipates heat through a cooling fan, which blows the heat into the storage chamber to heat the hydrogen storage tank and maintain its temperature. The cold air in the storage chamber can be returned to the fuel cell stack box through the ventilation channel to cool down the hydrogen reactor.

[0008] Furthermore, the lower tube is provided with a partition that separates the storage cavity and the ventilation channel, and the partition has a connecting hole.

[0009] Furthermore, an air inlet is provided on the bottom side of the front part of the lower tube, which connects to the air passage.

[0010] Furthermore, a pressure reducing valve is installed at the head of the hydrogen storage tank, and the pressure reducing valve is connected to an inlet valve via a pipeline and then connected to the hydrogen reactor.

[0011] Furthermore, a drain pipe is connected to the hydrogen reactor.

[0012] Furthermore, a drainage hole is provided at the bottom of the fuel cell stack box.

[0013] Furthermore, a cover plate is provided at the top of the lower tube.

[0014] Furthermore, a head tube is provided at the front end of the lower tube.

[0015] Furthermore, the rear end of the stack box is connected to a central tube and a bottom bracket.

[0016] Furthermore, a pressure transmitter is also installed between the hydrogen reactor and the hydrogen storage tank.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] 1. This utility model connects the lower pipe where the hydrogen storage tank is placed to the fuel cell stack box where the hydrogen reactor is installed, and directs the cooling fan towards the connection port, so that the heat generated during the operation of the hydrogen reactor can be blown into the lower pipe, thereby achieving heat transfer heating of the hydrogen storage tank to ensure the optimal operating temperature of the hydrogen storage tank. This not only improves the utilization rate of hydrogen, reduces the loss of hydrogen fuel cells, effectively extends their service life, and ensures the stability of the electric bicycle's performance, but also reduces energy consumption, realizes the reuse of thermal energy, and is beneficial to environmental protection.

[0019] 2. This utility model uses the heat dissipation energy of the hydrogen reactor to heat and keep the hydrogen storage tank warm, eliminating the need for heating with electric heating wires. This not only saves space inside the tube and optimizes the appearance, but also enables the reuse of heat energy, reduces energy consumption, saves costs, and is beneficial to the long-term operation of the battery.

[0020] 3. The design of the lower tube of this utility model is divided into an upper storage chamber and a lower ventilation channel, which allows the cold air that has been rapidly cooled by heat transfer from the hydrogen storage tank to flow into the lower ventilation channel and then back into the stack box to cool the hydrogen reactor. This achieves multiple benefits, improving the heat dissipation efficiency of the hydrogen reactor, reducing energy consumption, and alleviating the burden on the cooling fan, thus truly achieving energy recycling.

[0021] 4. This utility model, through the air inlet hole opened on the bottom side of the front part of the lower pipe, can assist the rapid flow of cold air in the ventilation duct, improve the efficiency of internal circulation, and ensure an excellent working environment.

Detailed Implementation

[0028] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] like Figure 1-5 As shown in this embodiment, a hydrogen intake and recirculation mode device for a hydrogen-powered electric vehicle is provided. It mainly consists of a lower pipe 1, a fuel cell stack 2, a hydrogen reactor 3, and a hydrogen storage tank 4. The lower pipe 1 is positioned at the front, and the fuel cell stack 2 is welded to the rear end of the lower pipe 1, with the two internally connected. The hydrogen reactor 3 is installed inside the fuel cell stack 2, near the connection point with the lower pipe 1. A cooling fan 30 is installed on the side of the hydrogen reactor 3 closest to the lower pipe 1, with the cooling fan 30 aligned with the connection point. The hydrogen storage tank 4 is installed inside the lower pipe 1. Thus, the heat generated during the operation of the hydrogen reactor 3 can be blown into the lower pipe 1 by the cooling fan 30, thereby achieving heat transfer heating of the hydrogen storage tank 4 to ensure its optimal operating temperature. This not only improves the utilization rate of hydrogen and reduces the loss of the hydrogen fuel cell, effectively extending its service life and ensuring the stability of the electric vehicle's performance, but also reduces energy consumption, realizes the reuse of thermal energy, and is beneficial to environmental protection. Furthermore, the hydrogen storage tank 4 is heated and kept warm by the heat dissipation energy of the hydrogen reactor 3, eliminating the need for heating with electric heating wires. This not only saves space in the tube 1 and optimizes the shape and appearance, but also enables the reuse of heat energy, reduces energy consumption, saves costs, and is beneficial for the battery's long-term operation.

[0030] Specifically, in this embodiment, a partition 8 is provided inside the lower pipe 1, which divides the lower pipe 1 into an upper storage chamber 101 and a lower ventilation channel 102. A hydrogen storage tank 4 is placed inside the storage chamber 101. A pressure reducing valve 40 is installed at the head of the hydrogen storage tank 4. The pressure reducing valve 40 is connected to an inlet valve 31 via a pipeline, and then connected to the hydrogen reactor 3. By controlling the opening of the pressure reducing valve 40 and the inlet valve 31, hydrogen from the hydrogen storage tank 4 can be supplied to the hydrogen reactor 3 for reaction.

[0031] To further realize the recycling of energy, a connecting hole 80 is provided on the partition 8 in this embodiment, that is, the upper storage cavity 101 and the lower ventilation channel 102 are connected. In this way, the cold air that has been rapidly cooled by heat transfer from the hydrogen storage tank 4 can flow into the lower ventilation channel 102, and then flow back into the fuel cell stack box 2 through the ventilation channel 102 to cool down the hydrogen reactor 3. This achieves multiple benefits, which can improve the heat dissipation efficiency of the hydrogen reactor 3, reduce energy consumption, reduce the burden on the cooling fan 30, and truly realize the recycling of energy.

[0032] To facilitate the flow of cold air, an air inlet 11 is provided on the bottom front side of the lower pipe 1 in this embodiment, which connects to the ventilation channel 102. In this way, the scooter can take in air through the air inlet 11 during its movement, and then push the cold air in the ventilation channel 102 to flow rapidly, thereby increasing the rate at which air enters the hydrogen reactor 3, improving the efficiency of the internal circulation, and ensuring an excellent working environment.

[0033] Specifically, in this embodiment, a drain pipe 21 is connected to the hydrogen reactor 3. The drain pipe 21 is used to discharge the only byproduct, water, which is environmentally friendly and pollution-free. A drain hole 20 is provided at the bottom of the stack box 2 to facilitate the drainage.

[0034] In addition, a cover plate 10 is provided on the top of the lower pipe 1 in this embodiment to facilitate the opening, closing, and replacement of the hydrogen storage tank 4. A head pipe 6 is welded to the front end of the lower pipe 1 to facilitate assembly with the front components of the electric bicycle. A middle pipe 5 and a bottom bracket 7 are also welded to the rear end of the fuel cell stack box 2 to facilitate assembly with the middle components of the electric bicycle. At the same time, a slot is provided on the middle pipe 5 to connect to the fuel cell stack box 2 so as to allow air to enter and be drawn into the hydrogen reactor 3.

[0035] Of course, in order to monitor, control and provide feedback on the hydrogen pressure status in real time, a pressure transmitter 9 is also installed between the hydrogen reactor 3 and the hydrogen storage tank 4 in this embodiment to ensure the safe and efficient operation of the hydrogen-powered vehicle.
