Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of a hydrogen-powered heavy-duty truck fuel cell engine, and in particular to an integrated hydrogen supply and heat dissipation system for a hydrogen-powered heavy-duty truck with an optimized layout. Background Art

[0002] The hydrogen fuel cell engine for heavy trucks is a power system designed for heavy trucks. It uses hydrogen as fuel and converts hydrogen and oxygen into electricity through electrochemical reactions, which in turn drives the motor to work. Compared with traditional internal combustion engines, fuel cell engines have the advantages of zero emissions (only water and heat are produced), high efficiency, and low noise. Fuel cells generate heat during operation, so an effective heat dissipation system is required to maintain the appropriate temperature to ensure the efficient operation of the fuel cell and extend its life.

[0003] In the field of hydrogen fuel cell engine heat dissipation for heavy-duty trucks, traditional technologies require a large number of low-pressure cooling fans (usually 8-10 are required), which are bulky and have limited placement. If the cooling fan is placed behind the hydrogen supply system, the air intake will be affected by the hydrogen cylinder; if it is placed on the left and right sides of the vehicle frame, the fan will be too long, affecting the lengthening of the wheelbase and the possibility of being too close to the ground, thus affecting the heat dissipation effect.

[0004] Therefore, an integrated hydrogen supply and heat dissipation system for hydrogen-powered heavy trucks with optimized layout is proposed. Summary of the invention

[0005] The present invention aims to solve the problems raised in the background technology and provides a hydrogen supply and heat dissipation integrated system for hydrogen-powered heavy trucks with an optimized layout.

[0031] Example

[0032] The optimized layout of the hydrogen heavy truck hydrogen supply and heat dissipation integrated system provided in this embodiment is as follows: Figure 1-Figure 4 As shown, it includes a hydrogen supply system and a radiator assembly.

[0033] The hydrogen supply system is used to supply hydrogen to hydrogen-powered heavy trucks. The hydrogen supply system has been designed with optimized structure and reserved upper installation space.

[0034] Among them, the radiator assembly is used to dissipate heat for the hydrogen heavy-duty truck fuel cell engine. The radiator assembly is arranged in the upper installation space of the hydrogen supply system and is divided into two heat dissipation modules 3. By adjusting the installation angles of the two heat dissipation modules 3, the air inlet area can be increased and the obstruction of the hydrogen heavy-duty truck compartment to the air outlet area can be reduced.

[0035] By optimizing the structure of the hydrogen supply system, especially the design of the hydrogen bottle frame and the fixing plate, installation space was successfully reserved on both sides of the upper part of the hydrogen bottle frame, which facilitated the layout of the radiator assembly.

[0036] This design not only improves space utilization, but also ensures effective isolation between the hydrogen supply system and radiator components, reducing mutual interference.

[0037] The radiator assembly is divided into two radiating modules 3, which are respectively arranged in the reserved installation space, thereby improving the heat dissipation efficiency.

[0038] By adjusting the installation angles of the two heat dissipation modules 3, the air inlet area is enlarged, so that air can flow into the radiator more smoothly, thereby improving the heat dissipation effect.

[0039] At the same time, the obstruction of the hydrogen heavy truck compartment to the air outlet area is reduced, so that the hot air blown out by the cooling fan 302 can be more effectively discharged outside the vehicle, avoiding the accumulation of hot air in the vehicle.

[0040] Specifically, in this embodiment, the hydrogen supply system includes a hydrogen bottle frame 1, at least two fixed plates 101 and a plurality of compressed hydrogen bottles 2. The upper installation space has two locations, which are symmetrically distributed on both sides of the upper part of the hydrogen bottle frame 1. The fixed plates 101 are fixedly installed inside the hydrogen bottle frame 1, and the plurality of compressed hydrogen bottles 2 are fixedly embedded on the fixed plates 101, and there is a gap between adjacent compressed hydrogen bottles 2 for use as ventilation ducts.

[0041] Specifically, in the present embodiment, four compressed hydrogen bottles 2 are provided, and the four compressed hydrogen bottles 2 are arranged in a scheme of three on the left and one on the right. The right compressed hydrogen bottle 2 is compressed between the two bottom compressed hydrogen bottles 2 to compress the width dimension of the hydrogen bottle frame 1, thereby reserving two installation spaces on the upper part of the hydrogen bottle frame 1 for arranging the radiator assembly.

[0042] A layout scheme of three compressed hydrogen bottles 2 on the left and one on the right is adopted, and the width dimension of the hydrogen bottle frame 1 is reduced by compressing the right hydrogen bottle 2, providing more space for the arrangement of the radiator assembly.

[0043] Ventilation ducts are left between adjacent compressed hydrogen bottles 2 to ensure air circulation between the hydrogen bottles, which is beneficial to heat dissipation and preventing the hydrogen bottles from overheating.

[0044] Specifically, in the present embodiment, the two heat dissipation modules 3 of the radiator assembly are respectively arranged in two installation spaces reserved on the upper part of the hydrogen bottle frame 1. The inclination angles of the two heat dissipation modules 3 are the same or similar to ensure the balance of the heat dissipation effect. Each heat dissipation module 3 includes a mounting plate 301 fixedly installed in the installation space reserved on the upper part of the hydrogen bottle frame 1 and four heat dissipation fans 302 embedded in the mounting plate 301. The heat dissipation fans 302 in each heat dissipation module 3 can be independently adjusted to adapt to different heat dissipation requirements.

[0045] The cooling fan 302 in each cooling module 3 can be adjusted independently, and the speed and power of the fan can be adjusted according to actual cooling requirements, thereby improving the flexibility and efficiency of cooling.

[0046] Specifically, in the present embodiment, a filter is provided at the air inlet of each cooling fan 302 to prevent dust and debris from entering the interior of the cooling fan 302 and affecting the service life and cooling effect of the cooling fan 302. The filter design at the air inlet effectively prevents dust and debris from entering the interior of the cooling fan 302, protects the fan blades and motor, and extends the service life of the fan.

[0047] Specifically, in the present embodiment, an air guide plate is provided at the air outlet of each cooling fan 302 to guide the wind blown out by the cooling fan 302 to the outside of the vehicle, thereby reducing the obstruction of the hydrogen-powered heavy truck compartment to the air outlet of the cooling fan 302. The air guide plate design at the air outlet can guide the wind blown out by the cooling fan 302 to the outside of the vehicle, thereby reducing the obstruction of the compartment to the air outlet of the cooling fan 302 and improving the heat dissipation effect. This design also helps to reduce the temperature in the compartment and improve the comfort of the cab.

[0048] Specifically, in the present embodiment, the radiator assembly includes a temperature monitoring device, which includes a temperature sensor and a controller. The temperature sensor is mounted on the hydrogen heavy-duty truck fuel cell engine, and the controller is mounted on the hydrogen bottle frame 1. The controller is electrically connected to the temperature sensor and the cooling fan 302, respectively. When the temperature sensor monitors that the temperature of the hydrogen heavy-duty truck fuel cell engine exceeds a set value, the controller controls the cooling fan 302 to dissipate heat and cool the hydrogen heavy-duty truck fuel cell engine. The temperature monitoring device can monitor the temperature of the fuel cell engine in real time, and control the start and stop of the cooling fan according to the temperature set value. This automatic control method not only improves the timeliness and accuracy of heat dissipation, but also reduces manual intervention and energy consumption.

[0049] Specifically, in this embodiment, the hydrogen supply system also includes a hydrogen pressure monitoring device, which is used to monitor the pressure in the compressed hydrogen bottle 2 in real time. The hydrogen pressure monitoring device includes a pressure sensor, which is fixedly mounted on the compressed hydrogen bottle 2, and the detection end of the pressure sensor extends into the interior of the compressed hydrogen bottle 2. The pressure sensor is connected to the controller signal to ensure the safety and stability of the hydrogen supply. The hydrogen pressure monitoring device can monitor the pressure in the compressed hydrogen bottle in real time to ensure the safety and stability of the hydrogen supply. Once the pressure abnormality is detected, the controller can immediately take corresponding safety measures, such as closing the hydrogen supply valve, etc., to prevent the occurrence of dangerous situations such as hydrogen leakage and explosion.

[0050] It is worth mentioning that the temperature sensor can be a pt100 temperature sensor, the controller can be a Siemens s7-300 series PLC controller, and the pressure sensor can be a DATA-52 series air pressure sensor.

[0051] In summary, the hydrogen supply and heat dissipation integrated system for hydrogen-powered heavy trucks with optimized layout provided in this embodiment has the following advantages:

[0052] The hydrogen supply and heat dissipation integrated system for hydrogen-powered heavy trucks with optimized layout provided in this embodiment realizes efficient integration of hydrogen supply and heat dissipation by optimizing the structural design of the hydrogen supply system and the arrangement of the radiator components. The system has the advantages of high space utilization, good heat dissipation effect, safety and reliability.

[0053] Working principle: The hydrogen supply system provides hydrogen supply to hydrogen heavy trucks through compressed hydrogen bottles and hydrogen pipelines; the radiator assembly dissipates the heat generated by the fuel cell engine into the air through components such as cooling fans and heat sinks. At the same time, the temperature monitoring device and the hydrogen pressure monitoring device monitor the temperature of the fuel cell engine and the pressure in the compressed hydrogen bottle in real time, and control the start and stop of the cooling fan and take corresponding safety measures according to the monitoring results.
