Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel technology, and in particular to a water-cooled two-wheeled vehicle integrated radiator and hydrogen stack cooling system. Background Technology

[0002] With increasing global focus on clean energy and sustainable transportation, hydrogen energy, as an efficient and clean energy source, is being increasingly widely used in the two-wheeled vehicle sector. Hydrogen-powered electric bicycles, mopeds, and other transportation vehicles are gradually becoming new choices for urban travel due to their zero emissions and high energy efficiency.

[0003] Currently, most hydrogen-powered electric bicycles and mopeds on the market use air-cooling systems. The chemical reaction between hydrogen and oxygen generates heat, and if this heat is not dissipated in time, it will severely affect the lifespan of the hydrogen stack. Generally, air-cooled hydrogen power systems employ an open air circuit structure, relying on natural airflow for heat dissipation. However, this cooling method has significant drawbacks for the entire hydrogen power system, specifically as follows:

[0004] 1. The air filter at the inlet of the air-cooled system often fails to completely filter out dust and impurities in the air. Long-term operation can easily lead to blockage of the fuel cell stack air path, affecting system performance.

[0005] 2. Directly blowing dry air onto the hydrogen stack can easily cause the proton exchange membrane to dry out, which in turn affects the efficiency of the hydrogen-oxygen reaction and reduces the overall performance of the system.

[0006] 3. The heat dissipation effect of the air-cooled system is affected by various factors such as ambient temperature and wind speed, making it difficult to ensure uniform heat dissipation in all parts of the hydrogen stack. This can easily lead to local overheating and affect the lifespan of the hydrogen system. Summary of the Invention

[0007] This invention overcomes the shortcomings of the prior art and provides a water-cooled two-wheeled vehicle integrated radiator and hydrogen stack cooling system.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water-cooled integrated radiator for two-wheeled vehicles, comprising: an upper water chamber, a lower water chamber disposed at the bottom of the upper water chamber, and a plurality of connecting plates fixed between the upper water chamber and the lower water chamber;

[0009] A plurality of heat sinks are installed between the plurality of connecting plates. The top of the heat sink is fixedly connected to the bottom of the upper water chamber, and the bottom is fixedly connected to the top of the lower water chamber. A plurality of heat dissipation channels are formed inside the heat sink.

[0010] A cooling inlet is fixed to the front of the upper water chamber, and a cooling outlet is fixed to the front of the lower water chamber. The interiors of the cooling inlet and the cooling outlet are respectively connected to the interiors of the upper water chamber and the lower water chamber.

[0011] In a preferred embodiment of this utility model, the top of the heat dissipation channel is connected to the interior of the upper water chamber, and the bottom is connected to the interior of the lower water chamber.

[0012] In a preferred embodiment of this utility model, an exhaust pipe is fixed to the top of the upper water chamber, and a one-way gas valve is installed inside the exhaust pipe.

[0013] In a preferred embodiment of this utility model, the flow direction of the gas check valve is from the inside of the upper water chamber to the outside.

[0014] In a preferred embodiment of this utility model, a filling port for adding coolant is fixed to the top of the upper water chamber.

[0015] In a preferred embodiment of the present invention, a plurality of heat sinks are uniformly distributed in a linear array between the upper water chamber and the lower water chamber; a plurality of heat dissipation channels are uniformly distributed in a linear array along the length of the heat sinks.

[0016] In a preferred embodiment of this utility model, mounting plates are fixed on both sides of the lower water chamber, and mounting holes are formed on the surface of the mounting plates.

[0017] This invention provides a hydrogen stack cooling system, including an integrated radiator as described in any one of the above-mentioned methods, and a water pump.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides an integrated radiator and hydrogen stack cooling system for a water-cooled two-wheeled vehicle. By adopting a radiator structure with an integrated expansion tank function, the hydrogen stack is cooled by water cooling circulation, avoiding the drawbacks of traditional air cooling. At the same time, the exhaust and water replenishment functions are combined in the upper water chamber of the radiator, which effectively solves the problems of large system space occupation, complex structure and high cost caused by the separate setting of expansion tank in traditional hydrogen-powered water-cooled two-wheeled vehicles. Furthermore, by increasing the volume of the upper water chamber of the radiator and arranging it at the highest point of the cooling system, the coolant is stored and pressure is balanced directly by the radiator. At the same time, the high-pressure gas generated by thermal expansion is automatically discharged through a one-way valve, which not only simplifies the cooling circuit structure, but also reduces the separate manufacturing cost of the expansion tank, making the hydrogen power system layout more compact and convenient for vehicle assembly and later maintenance.

[0026] Application Overview:

[0027] In existing technologies, water cooling technology has been introduced into the field of hydrogen-powered two-wheeled vehicles to overcome the limitations of air cooling technology. Water cooling technology removes the heat generated by the hydrogen stack through circulating coolant, offering advantages such as high heat dissipation efficiency and precise temperature control. However, when applied to two-wheeled vehicles, the small size and limited internal space of these vehicles present a significant challenge in arranging the water cooling system within that confined space.

[0028] Traditional water-cooling systems require multiple components such as expansion tanks, water pumps, and radiators, resulting in a complex system structure that increases manufacturing costs and maintenance difficulty. Furthermore, the large number of components in water-cooling systems leads to higher material and manufacturing costs, limiting their widespread application in the two-wheeled vehicle sector.

[0029] To address the limitations of existing water-cooling technology in the application of two-wheeled vehicles, this utility model proposes an integrated water-cooled radiator and hydrogen stack cooling system for two-wheeled vehicles. The water replenishment and venting functions of the expansion tank are integrated into the radiator, achieving a compact design of the cooling system and effectively solving the problems of space constraints and structural complexity.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, a water-cooled integrated radiator for a two-wheeled vehicle includes: an upper water chamber 1, a lower water chamber 2 disposed at the bottom of the upper water chamber 1, and several connecting plates 3 fixed between the upper water chamber 1 and the lower water chamber 2; several heat dissipation fins 4 are installed between the connecting plates 3, the top of the heat dissipation fins 4 is fixedly connected to the bottom of the upper water chamber 1, and the bottom is fixedly connected to the top of the lower water chamber 2; several heat dissipation channels 41 are opened inside the heat dissipation fins 4; a cooling inlet 5 is fixedly fixed on the front of the upper water chamber 1, and a cooling outlet 6 is fixedly fixed on the front of the lower water chamber 2, the interiors of the cooling inlet 5 and the cooling outlet 6 respectively communicate with the interiors of the upper water chamber 1 and the lower water chamber 2.

[0032] It should be noted that the top of the heat dissipation channel 41 is connected to the interior of the upper water chamber 1, and the bottom is connected to the interior of the lower water chamber 2; this can increase the volume of the upper water chamber 1 of the radiator, and the upper water chamber 1 of the radiator is arranged at the highest point of the cooling system in order to replenish and store coolant, maintain stable system water pressure, and use the upper water chamber of the radiator to replace the expansion tank.

[0033] Specifically, the coolant enters from the cooling inlet 5 of the upper water chamber 1, flows through the heat dissipation channel 41 inside the heat sink 4, exchanges heat with the outside air through the heat sink 4, dissipates the heat, then enters the lower water chamber 2, and finally flows out from the cooling outlet 6 of the lower water chamber 2, completing one cooling cycle.

[0034] In this embodiment, a plurality of heat sinks 4 are evenly distributed in a linear array between the upper water chamber 1 and the lower water chamber 2; a plurality of heat dissipation channels 41 are evenly distributed in a linear array along the length of the heat sinks 4; the uniform distribution ensures uniform flow of coolant within the heat sinks 4 and efficient heat dissipation.

[0035] In this embodiment, mounting plates 9 are fixed on both sides of the lower water chamber 2, and mounting holes 91 are provided on the surface of the mounting plates 9; the mounting plates 9 on both sides of the lower water chamber 2 and the mounting holes 91 thereon make it easy to fix the radiator at the highest point of the cooling system by means of connecting parts (such as bolts, nuts and screws).

[0036] Example 2

[0037] This embodiment is basically the same as embodiment 1, except that: an exhaust pipe 7 is fixed on the top of the upper water chamber 1, and a gas one-way valve is installed inside the exhaust pipe 7.

[0038] It should be noted that the flow direction of the gas check valve is from the inside of the upper water chamber 1 to the outside.

[0039] Specifically, during the operation of the cooling system, the coolant expands when heated, generating high-pressure gas. Since the high-pressure gas remains in the cooling system, it will affect the normal operation of the system. By setting the flow direction of the gas check valve in the exhaust pipe 7, when the internal pressure of the cooling system exceeds a certain threshold, the gas check valve opens, allowing the high-pressure gas to be discharged to the outside through the exhaust pipe 7, thereby maintaining the pressure stability inside the cooling system, effectively solving the problem of high-pressure gas inside the cooling system, and improving the safety and reliability of the system.

[0040] Example 3

[0041] This embodiment is basically the same as embodiment 2, except that: the top of the upper water chamber 1 is fixed with a filling port 8 for adding coolant.

[0042] Specifically, the addition of filler port 8 makes adding coolant more convenient, allowing for coolant replenishment without disassembling the radiator or other components. When the cooling system needs additional coolant, simply inject an appropriate amount of coolant into the radiator through filler port 8. This not only improves the ease of maintenance of the cooling system but also reduces maintenance costs and time.

[0043] This invention provides a hydrogen reactor cooling system, including an integrated radiator as described in any of the foregoing, and a water pump.

[0044] It should be noted that the cooling inlet 5 of the integrated radiator is connected to the coolant outlet of the hydrogen stack, and the cooling outlet 6 is connected to the input end of the water pump; the output end of the water pump is connected to the coolant inlet of the hydrogen stack.

[0045] Specifically, during system operation, the water pump draws coolant from the hydrogen stack, cools it through the integrated radiator, and then returns it to the hydrogen stack for recycling. The integrated radiator effectively cools the hydrogen stack, while the water pump's circulation ensures continuous flow and efficient heat dissipation of the coolant. The entire hydrogen stack cooling system is compact, efficient, and can effectively extend the service life of the hydrogen stack.

[0046] In use, this invention employs a water pump to extract the coolant, which has heated up due to the heat generated during operation, from the hydrogen stack. The coolant enters the upper water chamber 1 through the cooling inlet 5 of the integrated radiator, and then flows evenly through the heat dissipation channels 41 evenly distributed within the heat dissipation fins 4 between the upper and lower water chambers 2. Within the heat dissipation channels 41, the coolant exchanges heat with the outside air through the heat dissipation fins 4, dissipating heat and achieving a cooling effect. The cooled coolant then enters the lower water chamber 2 and finally flows out from the cooling outlet 6 of the lower water chamber 2, returning to the input end of the water pump, forming a complete cooling cycle. During this process, if the coolant expands due to heat, generating high-pressure gas... When the internal pressure of the cooling system exceeds a certain threshold, the gas check valve in the exhaust pipe 7 at the top of the upper water chamber 1 will automatically open, allowing high-pressure gas to be discharged to the outside, so as to maintain the pressure stability inside the cooling system. When coolant needs to be added, an appropriate amount of coolant can be injected directly into the radiator through the filling port 8 fixed at the top of the upper water chamber 1 without disassembling the radiator or other components, which greatly improves the maintenance convenience of the cooling system. The entire hydrogen stack cooling system achieves effective cooling of the hydrogen stack through the integrated radiator. At the same time, the circulation of the water pump ensures the continuous flow of coolant and efficient heat dissipation. The system has a compact structure, high efficiency, and can effectively extend the service life of the hydrogen stack.
