[0019] In another aspect, the present invention provides a method for using a thermal management hydrogen supply system suitable for small solid-state hydrogen storage, comprising the following steps:

[0020] Step 1: System initialization and monitoring preparation: Turn on the system power and start the system body in the touch panel. The data acquisition module in the system body starts working, establishes communication connection with the temperature sensor and pressure sensor, and collects temperature and pressure data in the storage tank in real time. Check the touch panel to confirm that all system components are in normal status and ensure that the equipment is ready.

[0021] Step 2, thermal management control: the data acquisition module transmits the collected temperature data to the data processing module, and the data processing module analyzes the data. If the temperature in the storage tank is lower than the set value, the data processing module transmits a signal to the control module. After receiving the signal, the control module controls the first pump to start, so that the heat medium in the heating chamber in the heating box flows in the pipeline. At the same time, the first three-way solenoid valve and the second three-way solenoid valve are controlled to switch to the heating mode, and the heat medium flows through the spring wire heating coil to heat the storage tank. If the temperature in the storage tank is higher than the set value, the data processing module sends an instruction to the control module, and the control module controls the second pump to start, the refrigerator starts working, and the temperature of the cooling pipe in the cooling box is reduced. The first three-way solenoid valve and the second three-way solenoid valve are controlled to switch to the cooling mode, and the cooling medium in the cooling pipe flows through the spring wire heating coil to cool the storage tank. At the same time, the fan is controlled to start to accelerate the heat dissipation of the heat sink fins and enhance the cooling effect.

[0022] Step 3: Hydrogen supply and safety control: During the thermal management process, the pressure sensor monitors the pressure in the storage tank in real time. When the pressure reaches the normal hydrogen supply pressure range, hydrogen supply can be performed. When the pressure in the storage tank is too high, the pressure sensor transmits the data to the data acquisition module. After analysis by the data processing module, the control module controls the electric pressure relief valve to open, releasing some hydrogen and reducing the pressure in the storage tank.

[0023] Step 4: System shutdown: After the hydrogen supply is completed, the system is shut down through the touch panel. After receiving the shutdown command, the control module controls the first pump, the second pump, the refrigerator, and the fan to stop working in sequence, and controls the first three-way solenoid valve, the second three-way solenoid valve, and the electric pressure relief valve to close.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the thermal management hydrogen supply system and method suitable for small solid-state hydrogen storage, by providing a heating box and a heating cavity and a heating pipe inside the heating box, the heating pipe can heat the medium in the heating cavity, provide a stable heat source for thermal management, and ensure that sufficient heat can be provided in time when heating is needed. The heated medium in the heating cavity is transported to the first three-way solenoid valve through the first pump, and then distributed to the spring wire heating coil through the first pump to achieve heating of the storage tank. The first pump provides power for the circulation of the heat medium to ensure the smooth progress of the heating process. The refrigerator cools the cooling pipe, and the spirally distributed cooling pipe increases the cooling area. To improve the cooling effect, the heat dissipation fins and the fan accelerate the heat dissipation, and work together to cool the cooling pipe in the cooling box, thereby providing a cold source for thermal management and meeting the cooling needs of the storage tank. The second pump transports the cooling medium in the cooling pipe to the first three-way solenoid valve, and then distributes it to the spring wire heating coil to cool the storage tank. The third connecting pipe enables the cooling medium to form a circulation loop in the cooling system, ensuring the continuous and stable cooling process and improving the cooling efficiency. By setting the first three-way solenoid valve and the second three-way solenoid valve, the same spring wire heating coil can be used to complete the cooling and heating of the storage tank, avoiding the complicated layout of pipes and lines on the storage tank.

[0045] See also Figure 8 The present invention provides a technical solution: a method for using a thermal management hydrogen supply system suitable for small solid-state hydrogen storage, comprising the following steps:

[0046] Step 1: System initialization and monitoring preparation: Turn on the system power supply, start the system body 105 in the touch panel 104, and the data acquisition module in the system body 105 starts working, establishes a communication connection with the temperature sensor 10302 and the pressure sensor 10303, and collects the temperature and pressure data in the storage tank 10301 in real time. Check the touch panel 104 to confirm that the status of each system component is normal and ensure that the equipment is ready;

[0047] Step 2: Thermal management and control: The data acquisition module transmits the collected temperature data to the data processing module, which analyzes the data. If the temperature in the storage tank 10301 is lower than the set value, the data processing module transmits the signal to the control module. After receiving the signal, the control module controls the first pump 10103 to start, so that the heat medium in the heating chamber 10104 in the heating box 10101 flows in the pipeline. At the same time, the first three-way solenoid valve 10307 and the second three-way solenoid valve 10308 are controlled to switch to the heating mode. The heat medium flows through the spring wire heating coil 10306 to heat the storage tank 10301. Heating: If the temperature in the storage tank 10301 is higher than the set value, the data processing module sends a command to the control module. The control module controls the second pump 10204 to start, the refrigerator 10208 to start working, the temperature of the cooling pipe 10207 in the cooling box 10201 to drop, and the first three-way solenoid valve 10307 and the second three-way solenoid valve 10308 to switch to the cooling mode.

At the same time, the fan 10203 is controlled to start, accelerating the heat dissipation of the heat sink 10202 to enhance the cooling effect.

[0048] Step 3: Hydrogen supply and safety control: During the thermal management process, the pressure sensor 10303 monitors the pressure in the storage tank 10301 in real time. When the pressure reaches the normal hydrogen supply pressure range, the hydrogen supply operation can be carried out. When the pressure in the storage tank 10301 is too high, the pressure sensor 10303 transmits the data to the data acquisition module. After analysis by the data processing module, the control module controls the electric pressure relief valve 10305 to open, releasing some hydrogen and reducing the pressure in the storage tank 10301.

[0049] Step 4, system shutdown: After the hydrogen supply is completed, the system is shut down through the touch panel 104.

After receiving the signal, the control module controls the first pump (10103) to start, so that the heat medium in the heating chamber (10104) in the heating box (10101) flows in the pipeline. At the same time, the first three-way solenoid valve (10307) and the second three-way solenoid valve (10308) are controlled to switch to the heating mode. The heat medium flows through the spring wire heating coil (10306) to heat the storage tank (10301). If the temperature in the storage tank (10301) is higher than the set value, the data processing module sends an instruction to the control module, and the control module controls the second pump (10204) to start, the refrigerator (10208) to start working, the temperature of the cooling pipe (10207) in the cooling box (10201) to decrease, and the first three-way solenoid valve (10307) and the second three-way solenoid valve (10308) are controlled to switch to the cooling mode, and the cooling medium in the cooling pipe (10207) flows through the spring wire heating coil (10306) to cool the storage tank (10301). At the same time, the fan (10203) is controlled to start, accelerating the heat dissipation of the heat dissipation fins (10202) to enhance the cooling effect; Step 3, hydrogen supply and safety control: During the thermal management process, the pressure sensor (10303) monitors the pressure in the storage tank (10301) in real time. When the pressure reaches the normal hydrogen supply pressure range, the hydrogen supply operation can be carried out. When the pressure in the storage tank (10301) is too high, the pressure sensor (10303) transmits the data to the data acquisition module. After analysis by the data processing module, the control module controls the electric pressure relief valve (10305) to open, release part of the hydrogen, and reduce the pressure in the storage tank (10301); Step 4, system shutdown: After the hydrogen supply is completed, the system is shut down through the touch panel (104). After receiving the shutdown command, the control module controls the first pump (10103), the second pump (10204), the refrigerator (10208), and the fan (10203) to stop working in sequence, and controls the first three-way solenoid valve (10307), the second three-way solenoid valve (10308), and the electric pressure relief valve (10305) to close.
