Description
Technical Field
The utility model relates to a accuse hydrogen module especially relates to a cartridge formula accuse hydrogen module for hydrogen fuel cell system.
Background
A hydrogen fuel cell vehicle is a vehicle using hydrogen as a main fuel, and as shown in fig. 1, the entire hydrogen system includes two parts, a hydrogen supply system and a fuel cell system.
The hydrogen supply system consists of a hydrogen cylinder, a combined cylinder valve, a pressure reducing valve, a pressure/temperature sensor and the like, and has the function of reducing the high-pressure hydrogen in the hydrogen cylinder to the medium pressure (10-30bar) so as to carry out the next adjustment.
The fuel cell system includes a hydrogen control module and a reactor stack (fuel cell stack). The hydrogen control module is used for providing low-pressure hydrogen with stable pressure for the fuel cell stack, and regulating and controlling the pressure and flow entering the reactor stack. The reactor includes peripheral devices such as an oxygen supply system, a water management system, a thermal management system, a control system, a safety system, etc., in addition to the fuel cell body.
At present, the hydrogen control module has three technical routes to achieve the purpose of pressure regulation:
1. the pressure is regulated using a spring pressure relief valve. The pressure reducing valve is a valve which reduces the inlet pressure to a certain required outlet pressure through regulating action and automatically keeps the outlet pressure stable by means of the energy of a medium.
2. The pressure was regulated using a solenoid proportional valve. When the electromagnetic proportional valve is electrified, different currents and electromagnetic forces are generated according to different electric signals, and the opening degree of the valve is controlled, so that the pressure of outlet hydrogen is controlled.
3. The pressure was regulated using a hydrogen injector. The injector in the hydrogen system is a unit formed by connecting a plurality of electromagnetic valves in parallel, and the downstream pressure can be adjusted by controlling the opening and closing of the electromagnetic valves with different numbers so as to change the number of flow passages.
A comparison of the three technical routes is shown in the following table:
| spring pressure reducing valve | Electromagnetic proportional valve | Hydrogen injector | |
| Whether or not power is required | Whether or not | Is that | Is that |
| Whether to consider explosion-proof | Whether or not | Is that | Is that |
| Whether or not to support remote control | Whether or not | Is that | Is that |
| Outlet pressure control accuracy | In | Height of | In |
| Whether or not there is noise | Is free of | Is free of | Is provided with |
| Degree of module complexity | Simple | Simple | Complexity of |
The module made of the hydrogen injector often has a plurality of electromagnetic valves, so that the module is relatively complex and does not conform to the design trend of simplification of the module. In order to improve the control of the system, the technology of the electromagnetic proportional valve capable of realizing remote control is more attractive than the technology of a spring pressure reducing valve, and the electromagnetic proportional valve has the most accurate control capability. Therefore, the hydrogen control module of the fuel cell system on the market is basically a product with the electromagnetic proportional valve technology as the core.
However, in the process of implementing the technical solution in the embodiment of the present application, the inventor finds that the above-mentioned technology has at least the following technical problems:
1. the existing hydrogen control module is large and heavy, the proportional electromagnetic valve of the type is large in size and heavy in mass, the area of connection with the module is large, and the size of a converging block of the hydrogen control module is influenced, so that the size and the weight of the whole module are greatly increased, and according to investigation and estimation, the single hydrogen control module is about 2.4kg-3.2 kg.
2. The proportional solenoid valve on the existing hydrogen control module has installation risks, and the proportional solenoid valve installed at the bottom of the type only needs to screw two diagonal long screws at the top of the valve during installation. The fixing mode of only two screws has uncertainty in vibration resistance and impact resistance.
3. The existing hydrogen control module is single in form, and the hydrogen control module has the function of connecting all functional parts together through the confluence block, so that once the state of the confluence block is determined, the number and the positions of elements of the parts on the hydrogen control module are fixed, and the hydrogen control module lacks structural diversity. The fuel system manufacturer customer must consider the wiring connection of the functional elements on the hydrogen control module when using, which increases the design difficulty of the customer.
4. The existing connector of the hydrogen control module is large in size, and the connector used by the electromagnetic proportional valve is generally DIN EN 17301-803A-type cable plug which is large in size and does not meet the requirements of vehicle regulation and miniaturization.
