[0073] After the hydrogen energy supply module is set, the hydrogen energy supply module is connected to the first hydrogen transmission line of the hydrogen internal combustion generator power supply module 200 to provide hydrogen to the hydrogen internal combustion generator power supply module 200 through the first hydrogen transmission line.

The first output path of the generator of the main hydrogen internal combustion generator power supply module 20 and the backup hydrogen internal combustion generator power supply module 21 is correspondingly connected to the main hydrogen power supply line 24 and the backup hydrogen power supply line 25 to transmit 240VDC (Voltage Direct Current, DC voltage) to the main hydrogen power supply line 24 and the backup hydrogen power supply line 25, so that the first electric energy obtained by the cabinet 70 is a DC voltage of 240V.

[0075] After the hydrogen energy supply module is set, the hydrogen energy supply module is connected to the second hydrogen transmission line of the hydrogen fuel cell power supply module 300 to provide hydrogen to the hydrogen fuel cell power supply module 300 through the second hydrogen transmission line. Specifically, in the present embodiment, the hydrogen fuel cell power supply module 300 includes a main hydrogen fuel cell power supply module 30 and a backup hydrogen fuel cell power supply module 31, and correspondingly, the second hydrogen transmission line includes a second main hydrogen transmission line 32 and a second backup hydrogen transmission line 33. Among them, the hydrogen energy supply module is connected to the main hydrogen fuel cell power supply module 30 through the second main hydrogen transmission line 32 to provide hydrogen to the main hydrogen fuel cell power supply module 30 through the second main hydrogen transmission line 32. The hydrogen energy supply module is connected to the backup hydrogen fuel cell power supply module 31 through the second backup hydrogen transmission line 33 to provide hydrogen to the backup hydrogen fuel cell power supply module 31 through the second backup hydrogen transmission line 33. After the main hydrogen fuel cell power supply module 30 and the backup hydrogen fuel cell power supply module 31 obtain hydrogen, the main hydrogen fuel cell power supply module 30 and the backup hydrogen fuel cell power supply module 31 respectively generate the second electric energy from the hydrogen provided by the hydrogen energy supply module according to the second preset operating condition. Among them, the second preset operating condition is to start the corresponding number of target fuel cell groups in the main hydrogen fuel cell power supply module 30 and the backup hydrogen fuel cell power supply module 31 according to the second power supply ratio to convert hydrogen energy into the second electric energy, and the sum of the first electric energy of the first power supply ratio and the second electric energy of the second power supply ratio is the total electric energy required by the cabinet 70. After the second electric energy is generated, the second electric energy is provided to the cabinet 70 through the hydrogen fuel cell power supply line. Specifically, corresponding to the main hydrogen fuel cell power supply module 30 and the backup hydrogen fuel cell power supply module 31, the hydrogen fuel cell power supply line includes a main hydrogen fuel cell power supply line 34 and a backup hydrogen fuel cell power supply line 35. The main hydrogen fuel cell power supply module 30 provides the second electric energy to the cabinet 70 through the main hydrogen fuel cell power supply line 34, and the backup hydrogen fuel cell power supply module 31 provides the second electric energy to the cabinet 70 through the backup hydrogen fuel cell power supply line 35. The main hydrogen fuel cell power supply line 34 and the backup hydrogen fuel cell power supply line 35 respectively include 240VHDC (VakilHousing Development Corporation, high density connector) for power transmission. The main hydrogen fuel cell power supply module 30 and the backup hydrogen fuel cell power supply module 31 select one for power supply. Generally, when the main hydrogen fuel cell power supply module 30 fails, the backup hydrogen fuel cell power supply module 31 is activated in time to ensure that the hydrogen fuel cell power supply module can always supply power to the cabinet 70.

[0076] In this embodiment, each fuel cell group in the main hydrogen fuel cell power supply module 30 and the backup hydrogen fuel cell power supply module 31 can provide a power generation power of not less than 100kW. The fuel cell group includes a hydrogen fuel cell group. The hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis, supplying hydrogen and oxygen to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load. The hydrogen fuel cell is a conventional device, and its specific structure is not described in detail here.

[0077] In this embodiment, the cabinet 70 is powered by a hydrogen internal combustion generator power supply module 200 and a hydrogen fuel cell power supply module 300. While meeting the power demand of the cabinet 70, it can be completely independent of the reliance on the mains, thereby eliminating the need for power capacity expansion. The hydrogen internal combustion generator power supply module 200 and the hydrogen fuel cell power supply module 300 each use a main and standby dual power supply, so that when one of the power supply modules fails, the other power supply module can continue to supply power to the cabinet 70, thereby achieving uninterrupted power supply to the cabinet 70.

[0078] The hydrogen internal combustion generator power supply module 200 and the hydrogen fuel cell power supply module 300 jointly supply power to the cabinet 70, and when supplying power together, the power supply ratio of the first power supply ratio provided by the hydrogen internal combustion generator power supply module 200 and the second power supply ratio provided by the hydrogen fuel cell power supply module 300 is 4:6. For example, the cabinet 70 requires 40kw of power, the hydrogen internal combustion generator power supply module 200 converts hydrogen energy into the first power supply ratio of 8kw in the full power state, and the hydrogen fuel cell power supply module 300 starts the corresponding number of target fuel cell groups in the hydrogen fuel cell power supply module 300 according to the second power supply ratio to convert hydrogen energy into the second power supply of 12kw. Further, considering that the fuel cell group in the hydrogen fuel cell power supply module 300 is sometimes not in working state, the hydrogen fuel cell power supply module 300 converts hydrogen energy into the second power supply ratio of 0kw-12kw of floating power, that is, corresponding to the 8kw-20kw floating power required by the cabinet 70.

[0079] In addition, considering that the number of cabinets 70 will continue to increase during use, the power required by the cabinet 70 also needs to be increased. At this time, the number of hydrogen internal combustion generator power supply modules 200 and / or hydrogen fuel cell power supply modules 300 can generally be increased to provide the increased power required by the cabinet 70. In this embodiment, it is preferred to increase the number of hydrogen fuel cell power supply modules 300 to provide the increased power required by the cabinet 70. Specifically, the hydrogen fuel cell power supply module 300 generates the third power from the hydrogen provided by the second hydrogen transmission line according to the third preset operating condition, and provides the third power to the cabinet 70 through the hydrogen fuel cell power supply line. Among them, the third preset operating condition is to start the corresponding number of target fuel cell groups in the hydrogen fuel cell power supply module 300 according to the third power supply ratio to convert hydrogen energy into the third power. The sum of the first power of the first power supply ratio, the second power of the second power supply ratio, and the third power of the third power supply ratio is the total power required by the cabinet 70. And the third power of the third power supply ratio is the floating power required by the cabinet 70 minus the first power of the first power supply ratio and the second power of the second power supply ratio.

[0080] Of course, in one example, the hydrogen internal combustion generator power supply module 200 and the hydrogen fuel cell power supply module 300 can supply power to the cabinet 70 separately.

[0081] In this embodiment, the cabinet 70 includes multiple servers. The server is the main power-consuming module, including a CPU, memory, hard disk, network card, supporting motherboard, chassis, etc.

[0082] In this embodiment, in order to further maintain the stability of power supply to the cabinet 70, it also includes: a diesel power supply module 400 for generating the fourth electric energy. The diesel power supply module 400 is connected to the cabinet 70 through the diesel power supply line to provide the fourth electric energy to the cabinet 70 through the diesel power supply line. Further, the diesel power supply module 400 includes a main diesel power supply module 40 and a standby diesel power supply module 41, and correspondingly, the diesel power supply line includes a main diesel power supply line 42 and a standby diesel power supply line 43. The main diesel power supply module 40 is connected to the cabinet 70 through the main diesel power supply line 42, and the standby diesel power supply module 41 is connected to the cabinet 70 through the standby diesel power supply line 43. The main diesel power supply module 40 and the standby diesel power supply module 41 are selected to supply power. Generally, when the main diesel power supply module 40 fails, the standby diesel power supply module 41 is enabled in time to ensure that the diesel power supply module 400 can always supply power to the cabinet 70. The output power of the main diesel power supply module 40 and the standby diesel power supply module 41 is 2000kw respectively. The main diesel power supply module 40 and the standby diesel power supply module 41 can provide 240V DC voltage to the cabinet 70 .

[0083] The main diesel power supply module 40 and the standby diesel power supply module 41 respectively include a diesel generator, wherein the main structure of the diesel generator includes a diesel engine and a generator, and the diesel engine is used as a power to drive the generator to generate electricity. The basic structure of the diesel engine includes: cylinder, piston, cylinder head, intake valve, exhaust valve, piston pin, connecting rod, crankshaft, bearing and flywheel and other components. The diesel engine of the diesel generator is generally a single-cylinder or multi-cylinder four-stroke diesel engine, and its working principle is as follows: the diesel engine is started by rotating the diesel engine crankshaft through manpower or other power to make the piston reciprocate up and down in the top closed cylinder. The piston completes four strokes during the movement: intake stroke, compression stroke, combustion and power (expansion) stroke and exhaust stroke. When the piston moves from top to bottom, the intake valve opens, and fresh air filtered by the air filter enters the cylinder to complete the intake stroke. The piston moves from bottom to top, the intake and exhaust valves are closed, the air is compressed, the temperature and pressure increase, and the compression process is completed. When the piston is about to reach the top, the injector sprays the filtered fuel into the combustion chamber in the form of mist and mixes with the high-temperature and high-pressure air, which immediately ignites and burns. The high pressure formed pushes the piston downward to work, drives the crankshaft to rotate, and completes the power stroke. After the power stroke is completed, the piston moves from bottom to top, and the exhaust valve opens to exhaust, completing the exhaust stroke. The crankshaft rotates half a circle for each stroke. After several working cycles, the diesel engine gradually accelerates to work under the inertia of the flywheel.

[0084] In this embodiment, the diesel power supply module 400 also includes a diesel steam boiler 44, which is connected to the waste heat output end of the hydrogen internal combustion generator power supply module 200 and the waste heat output end of the hydrogen fuel cell power supply module 300 to convert the waste heat of the hydrogen internal combustion generator power supply module 200 and the waste heat of the hydrogen fuel cell power supply module 300 into kinetic energy to drive the diesel steam boiler 44 to operate. In this embodiment, the input end of the diesel steam boiler 44 is connected to the waste heat output end of the hydrogen internal combustion generator power supply module 200 and the waste heat output end of the hydrogen fuel cell power supply module 300 through a second hot water steam pipeline 51, so as to transport the waste heat of the hydrogen internal combustion generator power supply module 200 and the waste heat of the hydrogen fuel cell power supply module 300 through the second hot water steam pipeline 51. And the second hot water steam pipeline 51 is connected to the first hot water steam pipeline 50 (described below). The working principle of the diesel steam boiler 44: the diesel pump sucks diesel out of the fuel tank and sends it to the ignition plug in the combustion chamber to ignite the mixture, and the exhaust gas from the combustion of diesel in the combustion chamber is discharged from the waste port. In order to make the fuel burn more fully, the diesel boiler must improve the atomization quality of the oil, the oil particles are fine and uniform, the atomization angle is appropriate, the oil mist is evenly distributed along the circumference, and can be fully mixed with the air. The burner releases heat by burning diesel, and then it is absorbed by the water-cooled wall through radiation heat transfer. The water in the water-cooled wall boils and vaporizes, generating a large amount of steam that enters the steam drum for steam-water separation (except for direct current furnaces). If it is a superheated steam boiler, the separated saturated steam enters the superheater, and continues to absorb the flue gas heat from the top of the furnace, the horizontal flue, and the tail flue through radiation and convection, and makes the superheated steam reach the required working temperature.

[0085] In this embodiment, the overall power supply mode of the system is as follows: the hydrogen internal combustion generator power supply module 200, the hydrogen fuel cell power supply module 300 energy storage battery (including the energy storage battery 201) and the diesel power supply module 400) all need to be converted to 240VDC and connected to the DC bus 80. The entire power supply system needs to be managed by the PMS (power production management system) to adjust the power generation power of the hydrogen fuel cell power supply module 300 energy storage battery to adapt to the power demand of the power consumption side (cabinet) (including the charging current demand after the energy storage battery 201 is discharged). When the hydrogen internal combustion generator power supply module 200 or the hydrogen fuel cell power supply module 300 energy storage battery is insufficient or fails, the energy storage battery seamlessly takes over the power supply to make up for the power difference, and starts the diesel generator to ensure power supply during the fault. The DC bus 80 also outputs to the inverter to supply the AC bus 81, which is used to supply the AC power supply equipment such as the air conditioner unit water pump. Because the power supply of the AC bus 81 comes from the DC bus 80, the DC bus 80 can ensure zero interruption, which can also ensure zero interruption of the AC bus 81. The reason why the AC power generated by the (hydrogen-diesel) internal combustion engine is not selected to supply the AC bus 81 is that zero interruption cannot be guaranteed.

[0086] In this embodiment, since the hydrogen internal combustion generator power supply module 200 and the hydrogen fuel cell power supply module 300 will generate a certain amount of heat when supplying power to the cabinet 70, in order to make full use of the heat, the power supply system also includes a lithium bromide absorption refrigeration module 600, wherein the input end of the lithium bromide absorption refrigeration module 600 is respectively connected to the waste heat output end of the hydrogen internal combustion generator power supply module 200 and the waste heat output end of the hydrogen fuel cell power supply module 300, so as to convert the waste heat of the hydrogen internal combustion generator power supply module 200 and the waste heat of the hydrogen fuel cell power supply module 300 into a condensing agent, and the condensing agent is transported through the refrigeration line 64 of the lithium bromide absorption refrigeration module 600 to cool the cabinet 70. Furthermore, the lithium bromide absorption refrigeration module 600 includes a heat exchanger and a refrigeration device. The input end of the heat exchanger is respectively connected to the waste heat output end of the hydrogen internal combustion generator power supply module 200 and the waste heat output end of the hydrogen fuel cell power supply module 300 to absorb the waste heat discharged by the hydrogen internal combustion generator power supply module 200 and the hydrogen fuel cell power supply module 300, and transmit the waste heat to the refrigeration device. The refrigeration device uses the waste heat as a driving energy source to achieve circulating refrigeration, and transports the condensing agent through the refrigeration line 64 to cool the cabinet 70.

[0087] In this embodiment, the input end of the lithium bromide absorption refrigeration module 600 is respectively connected to the waste heat output end of the hydrogen internal combustion generator power supply module 200 and the waste heat output end of the hydrogen fuel cell power supply module 300 through the first hot water steam pipe 50, so as to transport the waste heat of the hydrogen internal combustion generator power supply module 200 and the waste heat of the hydrogen fuel cell power supply module 300 through the first hot water steam pipe 50.

[0088] In this embodiment, the refrigeration device includes an evaporator 60, an absorber 61, a condenser 62 and a generator 63 which are interconnected. Among them, the evaporator 60 is to place the refrigerant water in a sealed container so that the container is close to a vacuum state (6 mmHg), and the water evaporates at 4°C. After the cold water passes through the container, it absorbs heat and can produce 7°C cold water (refrigerant water). When the absorption liquid of the generator 63 absorbs the refrigerant vapor, the absorption energy decreases as the concentration decreases. In order to restore the absorption capacity, the absorption liquid is transported to another container for heating and separation of the refrigerant vapor (the absorption liquid evaporates the refrigerant vapor and is concentrated, and then sent back to the absorber 61, completing the circulation of the solution, so that the refrigeration continues). The dilute lithium bromide solution is transported to the generator 63 by the solution pump. Under the heating of the waste heat of the heat exchanger, the dilute lithium bromide solution becomes a concentrated solution, and refrigerant vapor is generated at the same time. The temperature of lithium bromide concentrated solution is relatively high, while lithium bromide dilute solution needs to be heated. In order to make full use of energy, a heat exchanger is set in the process of lithium bromide concentrated solution flowing back to absorber 61 from generator 63 and lithium bromide dilute solution being transported from absorber 61 to generator 63, so that the two can exchange heat. The LiBr solution in absorber 61 has strong absorption, and the higher the concentration of the solution and the lower the temperature, the stronger its absorption. Lithium bromide (LiBr) aqueous solution is used as an absorbent to absorb refrigerant vapor in the container. The cooling water in the copper tube of condenser 62 is cooled to condense the refrigerant vapor from generator 63 into liquid water. The liquid water flows back to evaporator 60 to continue evaporation and heat absorption, so that the refrigerant water in evaporator 60 is continuously replenished. At this point, a complete refrigeration cycle is completed. The cooling water enters the (evaporation) cooling tower from the outlet, and under the action of the cooling tower fan, the heat therein is dissipated into the atmosphere, the temperature drops to 32°C, and then enters the refrigeration device from the cooling water inlet. This cycle repeats. After being transported by the refrigeration line 64 of the refrigeration device, the refrigerant water (condensing agent) enters the cabinet 70 to deliver the cold to the location where refrigeration is required.

[0089] It should be noted that each device in the above-mentioned refrigeration device has a pump body 90 (such as a water pump, a heat pump, etc., which can transport heat energy). In order to enable each pump body 90 to operate normally, this embodiment is also provided with an AC bus 81, one end of which is connected to the DC bus 80. The hydrogen internal combustion generator power supply module 200, the hydrogen fuel cell power supply module 300 and the diesel power supply module 400 all need to be converted into 240DC and connected to the DC bus 80 (or the hydrogen internal combustion generator power supply module 200, the hydrogen fuel cell power supply module 300 and the diesel power supply module 400 can generate AC power through their respective inverters). The DC bus 80 outputs to the inverter to supply the AC bus 81, and the other end of the AC bus 81 can be connected to each pump body 90, so that the AC power transmitted by the AC bus 81 is used to power each pump body 90.
