[0002] With the continuous development of the cold chain logistics industry, refrigerated containers are becoming more and more widely used as the main carrier of cold chain logistics transportation. At present, refrigerated containers are mainly powered by diesel generators for their refrigeration units. The combustion of diesel produces a large amount of carbon dioxide, nitrogen oxides and sulfur-phosphorus compounds, and the fuel tank itself has the potential for fuel leakage, which will pollute the environment. With the continuous maturity of fuel cell system technology, it has been widely used in commercial vehicles, energy storage, aerospace and other fields. The use of traditional diesel generators to provide power for refrigerated containers is not conducive to environmental protection; and the lithium battery power system has the disadvantages of power loss and slow start in low temperature environments. The refrigeration unit of the refrigerated container has the characteristics of frequent start and stop and low power when working. The lithium battery has failed at an ambient temperature of minus 30 degrees Celsius, and the normal start of the refrigerated container cannot be guaranteed under low temperature conditions.

[0043] In some embodiments of the present application, a hydrogen energy refrigerated container is provided, which mainly uses hydrogen fuel as the main energy source to provide refrigeration for the refrigerated container. The product of hydrogen fuel in the working process of the refrigeration unit is water, which can achieve zero pollution emission during the use of the container.

[0044] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 3 As shown, the hydrogen energy refrigerated container includes a refrigerated container body 100, a refrigeration unit 200 and a hydrogen fuel cell power system.

[0045] The refrigerated container body 100 includes a front end 110 and a door end 120 that are disposed opposite to each other. An inner cavity 130 is formed in the refrigerated container body 100 .

[0046] The refrigeration unit 200 and the hydrogen fuel cell power system are arranged at the front end of the refrigerated container body 100 .

[0047] The refrigeration unit 200 is used to provide a cold source for the inner cavity 130 of the refrigerated container body 100 .

[0048] The hydrogen fuel cell power system includes a power battery module 310 and a hydrogen fuel cell module. The power battery module 310 is used as a starting power source for the hydrogen fuel cell module.

[0049] The power battery module 310 can meet normal starting requirements at minus 30 degrees Celsius, thus solving the problem that lithium batteries cannot be used stably as starting power sources in low temperature environments.

[0050] The hydrogen fuel cell module includes a hydrogen fuel cell 321 and a hydrogen storage assembly. The hydrogen storage assembly is used to store hydrogen. The hydrogen storage assembly is used to supply hydrogen to the hydrogen fuel cell 321. The hydrogen fuel cell 321 is used to supply energy to the refrigeration unit 200.

[0051] In some embodiments of the present application, the power battery module 310 may also be used to supply energy to the refrigeration unit 200 .

[0052] In some embodiments of the present application, in order to achieve control of the power battery module 310, the hydrogen fuel cell module and the refrigeration unit 200, the hydrogen fuel cell power system also includes a control module 330, and the control module 330 is electrically connected to the power battery module 310, the hydrogen fuel cell module and the refrigeration unit 200.

[0053] After the refrigeration unit 200 is started, the control module 330 is configured to start the power battery module 310 to supply power to the hydrogen fuel cell module in the first working state, thereby starting the hydrogen fuel cell module to supply energy to the refrigeration unit 200;

[0054] The control module 330 is configured to cut off the hydrogen storage component from supplying hydrogen to the hydrogen fuel cell 321 and start the power battery module 310 to supply energy to the refrigeration unit 200 in the second working state.

[0055] In some embodiments of the present application, the first working state is the preferred working state, that is, the preferred energy supply component of the refrigeration unit 200 is the hydrogen fuel cell 321; the second working state is the backup working state, that is, when the hydrogen fuel cell 321 cannot normally supply energy to the refrigeration unit 200, the power battery module 310 serves as a backup energy supply component.

[0056] The power battery module 310 uses a high-power power battery, which can provide power to the refrigeration unit 200 for more than 30 minutes once the main power supply system fails.

[0057] The switching between the first working state and the second working state is controlled by the control module 330 .

[0058] Specifically, the hydrogen storage assembly includes a plurality of high-pressure hydrogen storage bottles 3221 connected in series.

[0059] In order to ensure that the hydrogen fuel cell 321 can provide energy for the refrigeration unit 200 for a long time, a plurality of high-pressure hydrogen storage bottles 3221 need to be provided, and the plurality of high-pressure hydrogen storage bottles 3221 need to be connected in series for use.

[0060] Specifically, the specific number of high-pressure hydrogen storage bottles 3221 is determined according to the remaining space at the front end 110 of the refrigerated container body 100 .

[0061] In some embodiments of the present application, the hydrogen storage assembly further includes a gas pressure detection component, which is used to detect the gas pressure of the high-pressure hydrogen storage bottle 3221 and display the remaining hydrogen in the high-pressure hydrogen storage bottle 3221.

[0062] The air pressure detection component is electrically connected to the control module 330 . The air pressure detection component feeds back the hydrogen remaining amount of the high-pressure hydrogen storage bottle 3221 detected by it to the control module 330 . The control module 330 calculates the total amount of hydrogen stored in the multiple high-pressure hydrogen storage bottles 3221 .

[0063] A set value for the minimum hydrogen content needs to be set in the control module 330. When the total amount of hydrogen stored in the multiple high-pressure hydrogen storage bottles 3221 detected and calculated by the control module 330 is less than the set value, the control module 330 controls the hydrogen storage component to stop supplying hydrogen to the hydrogen fuel cell 321, and the control module 330 starts the power battery module 310 to supply energy to the refrigeration unit 200.

[0064] In some embodiments of the present application, the hydrogen storage assembly further includes a hydrogen leakage alarm component, which is used to detect the hydrogen concentration in the front end 110 of the refrigerated container body 100 .

[0065] The hydrogen leakage alarm component is electrically connected to the control module 330. When the hydrogen leakage alarm component alarms, the control module 330 receives the signal of the hydrogen leakage alarm component and cuts off the hydrogen storage component from supplying hydrogen to the hydrogen fuel cell 321. In this case, the control module 330 stops the first working state and starts the second working state, that is, the control module 330 starts the power battery module 310, and the power battery module 310 supplies energy to the refrigeration unit 200. The power battery module 310 serves as a backup power supply and an emergency power supply. The power battery module 310 can meet the continuous operation of the refrigeration unit 200 for more than 30 minutes, leaving sufficient time for the emergency transportation of goods to the cold storage.

The refrigeration unit 200 is arranged above the hydrogen storage assembly, and a first fireproof and heat-insulating layer 410 is arranged between the refrigeration unit 200 and the hydrogen storage assembly. The first fireproof and heat-insulating layer 410 is used to effectively protect the refrigeration unit from being burned in the event of a fire.

[0067] In some embodiments of the application, the hydrogen fuel cell 321 and the power battery module 310 are located below the hydrogen storage assembly, and a second fireproof and heat-insulating layer is provided between the hydrogen fuel cell 321, the power battery module 310 and the hydrogen storage assembly.

[0068] Specifically, the material of the first fireproof and heat-insulating layer 410 may be an aluminum alloy skeleton and an aerogel pad.

[0069] In some embodiments of the present application, a cooling system is further included. The cooling system includes a heat dissipation module. The heat dissipation module is disposed at the front end 110 of the refrigerated container body 100. The heat dissipation module is disposed at one side of the hydrogen fuel cell power system.

[0071] The heat dissipation module is used to dissipate heat from the hydrogen fuel cell power system.

[0072] In some embodiments of the present application, the cooling system 500 further includes a ventilation window. The ventilation window is opened at the front end 110 of the refrigerated container body 100 and is located on the same side as the heat dissipation module.
