[0027] In the embodiment, the air cooling mechanism comprises an air compressor 4 and an air supply pipe 5 connected to each other, one side of the air supply pipe 5 is arranged around the hydrogen storage support 2 and corresponds to the periphery of the solid-state hydrogen storage unit 3, a plurality of air blowing holes facing the solid-state hydrogen storage unit 3 are arranged on the pipe wall of the air supply pipe 5, the arrangement can greatly improve the flow rate of the cold air blown out of the air blowing hole, further improve the evaporation rate of the heat dissipation medium on the surface of the solid-state hydrogen storage unit 3, quickly remove the heat on the surface of the solid-state hydrogen storage unit 3, make the cooling and temperature reduction rate of the solid-state hydrogen storage unit 3 faster, and meanwhile, the concentration of escaped hydrogen in the solid-state hydrogen charging machine is rapidly reduced, thereby further improving the safety.

[0028] In this embodiment, the hydrogen storage support 2 is a hollow cuboid support, which is provided with a plurality of placement positions arranged in a matrix, and the solid-state hydrogen storage units 3 are installed in the placement positions one by one. One side of the air supply pipe 5 is spirally arranged on the hydrogen storage support 2.

[0030] In this embodiment, the solid-state hydrogen storage unit 3 is a solid-state hydrogen storage bottle (or solid-state hydrogen storage tank) filled with hydrogen storage alloy material, and the number of solid-state hydrogen storage bottles is 4. Of course, other numbers of solid-state hydrogen storage bottles can be set according to needs, such as 2, 6, or 8. The shell 1 is a vertical cuboid shell 1 with a loading and unloading port 10 on one side. The bottom of the shell 1 is provided with a support rail 12.

The top end of the support rail 12 is higher than the bottom edge of the loading and unloading port 10. This arrangement makes the solid-state hydrogen storage mechanism composed of the hydrogen storage support 2 and the solid-state hydrogen storage bottles an independent modular mechanism, so that during hydrogen charging, multiple solid-state hydrogen storage bottles can be installed on the hydrogen storage support 2 together, and then the hydrogen storage support 2 with the solid-state hydrogen storage bottles is lifted by a forklift and installed on the support rail 12 in the shell 1, thereby realizing batch installation of the solid-state hydrogen storage bottles.

[0031] In this embodiment, a plurality of heat dissipation and hydrogen dissipation holes 11 are formed in the top and bottom of the shell 1, so that the water mist vaporized in the shell 1 and the escaped hydrogen can quickly escape to the outside of the shell 1 through the heat dissipation and hydrogen dissipation holes 11, avoiding the formation of a high-temperature and high-humidity environment in the shell 1, reducing the temperature inside the solid-state hydrogen charging machine, and ensuring the safety of the solid-state hydrogen storage unit 3.

[0032] In this embodiment, a control module and a sensor group are further provided in the solid-state hydrogen storage mechanism. The sensor group, the fog cooling mechanism, and the air cooling mechanism are in communication connection with the control module. The sensor group includes a temperature sensor, a humidity sensor, and a pressure sensor. During hydrogen charging, the temperature sensor is connected to a proper position to detect the bottle wall temperature of the solid-state hydrogen storage bottle. The hydrogen charging amount is estimated by parameters such as room temperature, bottle wall temperature, mass flow meter, and thermal conductivity of the solid-state hydrogen storage bottle.

[0033] In the embodiment, the hydrogen filling module 13 is further included, which comprises a hydrogen inlet pipeline connected to the solid-state hydrogen storage unit 3, one end of the hydrogen inlet pipeline is connected to a hydrogen source, and a mass flow meter, an electromagnetic valve, a pressure reducing valve, a pressure relief valve and a hydrogen detector are installed on the hydrogen inlet pipeline and are in communication connection with the control module. The mass flow meter records the amount of hydrogen absorbed by the solid-state hydrogen storage bottle each time, and simultaneously transmits the hydrogen absorption data to the control module. The electromagnetic valve controls the sending, shutdown and pressure relief of hydrogen of the solid-state hydrogen filling machine. The pressure sensor detects the running hydrogen pressure of the solid-state hydrogen filling machine. If the pressure is too high, the control module will command the inlet electromagnetic valve to close and the pressure relief electromagnetic valve to open, and at the same time, the control module will issue an alarm sound to prompt the maintenance of the pressure system (inlet pressure reducing valve, etc.). The temperature sensor and the mass flow meter monitor the hydrogen filling process of the solid-state hydrogen filling machine.

[0034] The solid-state hydrogen filling machine can be customized with different system operating pressures and operating environments according to customer requirements, and the operation reliability can be realized by selecting and matching pressure reducing valves, pressure relief valves, explosion-proof boxes, etc. The power supply of the embodiment includes a weak current system and a strong current system. The temperature sensor, the pressure sensor, the mass flow meter, the electromagnetic valve, the hydrogen detector, etc. are connected to the weak current system, and the weak current system and the power supply module of the fog cooling mechanism and the air cooling mechanism are connected to the strong current system.

[0035] In summary, the solid-state hydrogen filling machine sprays water mist through the fog cooling mechanism to increase the humidity in the solid-state hydrogen filling machine, so that the atomized heat dissipation medium evaporates to reduce the temperature of the surface of the solid-state hydrogen storage unit 3, thereby achieving the effect of atomized cooling, and eliminating static electricity generated in the solid-state hydrogen storage machine, ensuring the safety of hydrogen filling. The air cooling mechanism blows cold air to the solid-state hydrogen storage unit 3 to increase the air flow rate in the solid-state hydrogen filling machine, thereby accelerating the evaporation rate of the heat dissipation medium around the solid-state hydrogen storage unit 3, thereby quickly removing the heat on the surface of the solid-state hydrogen storage unit 3 to achieve rapid cooling, and quickly reducing the concentration of escaped hydrogen in the solid-state hydrogen storage machine. The combination of the two enables the heat conducted to the bottle wall in the solid-state hydrogen storage bottle during the hydrogen filling process of the solid-state hydrogen filling machine to be quickly absorbed and conducted to the outside of the solid-state hydrogen filling machine by means of the water mist evaporated on the bottle wall of the solid-state hydrogen storage bottle and the high-flow cold air, so that the hydrogen storage material in the solid-state hydrogen storage bottle can continuously absorb hydrogen, and the hydrogen filling process is more stable and reliable, and the safety is better. In addition, the solid-state hydrogen filling machine can be used as a fixed solid-state hydrogen storage system for hydrogen filling work, and can also be used with a heating sleeve during use, so that hydrogen filling and hydrogen release work can be realized, and the solid-state hydrogen filling machine is modularly arranged, and a plurality of solid-state hydrogen filling machines can be connected in parallel or series to form a solid-state hydrogen filling unit. The control module, the fog cooling mechanism and the air cooling mechanism of the solid-state hydrogen filling unit are uniformly adjusted and controlled.
