Description

Technical Field

[0001] This invention relates to the field of data centers, and in particular to an edge computing liquid-cooled cabinet with an on-site hydrogen production fuel cell power system. Background Technology

[0002] With the advent of the 5G era, the volume of communication data is rapidly increasing. Simultaneously, server performance, power consumption, and deployment scale are also growing, and the deployment of edge data centers is rapidly advancing with the application scenarios of 5G and the Internet of Things. The large number of edge data centers brings significant energy consumption, and their decentralized and flexible deployment also presents challenges for server power supply. Especially for some scientific research and military applications, edge computer cabinets need to be deployed in extremely harsh environments. Outdoors, there is often no stable and continuous high-power power supply, and the server's cooling system faces enormous challenges in dusty environments.

[0003] Hydrogen energy is a relatively mature new energy technology, and there are already some studies that combine hydrogen energy with data center power supply systems. However, most current technologies involve hydrogen storage, and direct hydrogen storage has problems such as low energy density, large volume, and dangerous storage and transportation, which poses a significant challenge to the reliability design of edge data centers.

[0004] Therefore, researching highly reliable server rack-level on-site hydrogen fuel cell power systems suitable for complex outdoor environments is an important direction for the future development of data centers. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings and deficiencies of the prior art, the purpose of this invention is to provide an edge computing liquid-cooled cabinet with an on-site hydrogen production fuel cell power system, which is suitable for complex outdoor environments.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An edge computing liquid-cooled cabinet with an on-site hydrogen production fuel cell power system includes: an on-site hydrogen production fuel cell module, a liquid-cooled server, a refrigerant distribution module, a PDU, and a lithium battery module, wherein the liquid-cooled server, the lithium battery module, the refrigerant distribution module, and the PDU are housed inside the cabinet, and the on-site hydrogen production fuel cell module is housed outside the cabinet.

[0008] The PDU is electrically connected to the liquid-cooled server, the on-site hydrogen production fuel cell module, and the lithium battery module, respectively. The lithium battery module is connected to the on-site hydrogen production fuel cell module to form a power supply circuit.

[0009] The on-site hydrogen production fuel cell module is connected to the refrigerant distribution module, which in turn is connected to the liquid cooling server, forming a cooling loop.

[0010] Furthermore, the on-site hydrogen production fuel cell module includes a fuel tank, a reforming reaction unit, a heat exchange unit, a fuel cell unit, a control unit, and a compressor. The fuel tank inputs liquid alcohol and air to the reforming reaction unit, the reforming reaction unit generates syngas which is input to the heat exchange unit, and the fuel cell unit uses the syngas containing hydrogen to react with the air provided by the fuel tank to generate direct current for use by the liquid cooling cabinet.

[0011] The refrigerant distribution module is connected to the refrigerant inlet of the reforming reaction unit via the compressor, and the refrigerant outlet of the reforming reaction unit is connected to the heat exchange unit via the throttling valve. The heat exchange unit is connected to the refrigerant distribution module, forming a cooling circuit.

[0012] The control unit is electrically connected to the fuel cell unit, the lithium battery module, and the liquid-cooled server, respectively.

[0013] Furthermore, the reforming reaction unit includes at least one set of reaction units, each set of reaction units including a preheating plate, an evaporation plate, a combustion plate, a reforming reaction plate and a carbon monoxide removal plate stacked in sequence.

[0014] Furthermore, the evaporation plate, combustion plate, reforming reaction plate, and carbon monoxide removal plate are all processed with reaction chambers. Foam metal or microchannel arrays are placed in the reaction chambers and coated with reaction catalysts. The preheating plate is processed with heat exchange chambers, and microchannel arrays are processed in the heat exchange chambers.

[0015] Furthermore, the number of distribution interfaces of the refrigerant distribution module is the same as the number of liquid-cooled servers, and it is connected to the liquid-cooled servers through n pairs of cooling hoses.

[0016] Furthermore, the fuel cell unit employs a proton exchange membrane fuel cell.

[0017] Furthermore, it also includes feeding unreacted hydrogen from the fuel cell unit into a heat exchange module for cooling before feeding it into the reforming reaction unit.

[0018] Furthermore, the reforming reaction unit includes a reforming reaction circuit and a combustion reaction circuit;

[0019] The reforming reaction pathway is specifically as follows:

[0020] Liquid alcohol solution and air enter the reforming reaction unit. In the evaporation plate, the liquid alcohol solution absorbs heat and vaporizes, then mixes with air to form a mixed gas. The initial heat of the reaction is provided by the preheating plate. The mixed gas then enters the reforming reaction plate. Under high temperature and the action of the catalyst, the mixed gas undergoes an autothermal reforming reaction and is transformed into a hydrogen-containing synthesis gas. The synthesis gas then enters the carbon monoxide removal plate. After the action of the catalyst, the carbon monoxide content in the synthesis gas is reduced and discharged from the reforming reaction unit.

[0021] The combustion reaction circuit:

[0022] Hydrogen enters the combustion plate and burns under the action of a catalyst, providing heat for the reaction in the evaporation plate and reforming reaction plate. The reaction gas is then discharged from the reforming reaction unit.

[0023] Furthermore, the cooling circuit specifically comprises:

[0024] The compressor compresses low-pressure gaseous refrigerant into the preheating plate through the refrigerant inlet. Inside the preheating plate, the low-pressure gaseous refrigerant is compressed into high-pressure liquid refrigerant and releases heat. This heat heats the gas mixture. Subsequently, the high-pressure liquid refrigerant flows out of the reforming reaction unit and through the second refrigerant pipeline to the heat exchange unit. During this process, the pressure decreases as it flows through the expansion valve, and the low-pressure liquid refrigerant flows into the heat exchange unit. Some of the low-pressure liquid refrigerant absorbs heat from the syngas and vaporizes as it flows through the heat exchange unit, cooling the syngas. It then flows out of the heat exchange unit with the remaining liquid refrigerant. The remaining low-pressure liquid refrigerant then flows into the cold plate inside the liquid-cooled server through the third refrigerant pipeline. Inside the cold plate, the remaining low-pressure liquid refrigerant absorbs heat from the liquid-cooled server components and vaporizes. All the liquid refrigerant vaporizes into low-pressure gaseous refrigerant, which is then drawn into the compressor to complete one cooling cycle.

[0025] Furthermore, the heat exchange unit is a plate heat exchanger.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] By using stacked on-site hydrogen production technology, hydrogen can be generated on-site to power fuel cells, avoiding the safety hazards associated with hydrogen storage devices used in traditional fuel cell systems.

[0028] The stacked reforming reactor is equipped with a microchannel structure or a foam metal structure, which increases the reaction area within the same volume. The stacked structure can be expanded or reduced according to the reaction requirements, realizing the miniaturization of the device and enhancing the flexibility of equipment layout.

[0029] The heat pump system collects the heat generated by the server components to provide heat for the reforming hydrogen production reaction. This eliminates the problem of dust accumulation and blockage in the heat sink of traditional liquid cooling solutions in environments with poor air quality, and reduces the impact of ambient temperature on the performance of the cooling system. It effectively solves the heat dissipation problem of high-performance edge computing servers in extremely harsh environments.

[0030] The integration of on-site reforming hydrogen production technology with server racks enables the combination of new energy sources and server systems. This effectively reduces the server system's dependence on electricity and enhances the deployment flexibility of server racks for outdoor scenarios such as edge computing.

[0037] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0038] Figure 1 An edge computing liquid-cooled cabinet with an on-site hydrogen production fuel cell power system includes: an on-site hydrogen production fuel cell module 1, a cabinet 2, a liquid-cooled server 3, a refrigerant distribution module 4, a PDU 5 (power distribution unit), and a lithium battery module 6. The liquid-cooled server 3, refrigerant distribution module 4, PDU 5, and lithium battery module 6 are housed within the cabinet 2, while the on-site hydrogen production fuel cell module 1 is located at the rear of the cabinet 2. The liquid-cooled server 3 is a cold-plate type liquid-cooled server. The on-site hydrogen production fuel cell module 1, liquid-cooled server 3, and refrigerant distribution module 4 constitute the cooling system; the on-site hydrogen production fuel cell module 1 constitutes the reforming reaction hydrogen production system; and the on-site hydrogen production fuel cell module 1, liquid-cooled server 3, PDU 5, and lithium battery module 6 constitute the power supply system.

[0039] like Figure 1 and Figure 2 As shown, one side of PDU 5 is electrically connected to the liquid-cooled server 3 via multiple pairs of cables 503. The connection between the liquid-cooled server 3 and PDU 5 is in parallel. The first power supply port 501 is electrically connected to the fuel cell unit 14 inside the on-site hydrogen production fuel cell module 1 via the first power supply line 204. The second power supply port 502 is electrically connected to one side of the lithium battery module 6 via the second power supply line 203. The other side of the lithium battery module 6 is electrically connected to the fuel cell unit 14 inside the on-site hydrogen production fuel cell module 1 via the third power supply line 1404. The above connections constitute the power supply circuit of the system. Figure 2Based on the power system principle, the fuel cell unit 14 is electrically connected to the lithium battery module 6, and also electrically connected to the PDU 5. The lithium battery module 6 is electrically connected to the PDU 5, and the PDU 5 is electrically connected to the liquid-cooled server 3. The control module 15 is electrically connected to the fuel cell unit 14, the lithium battery module 6, and the liquid-cooled server 3 respectively. The lithium battery module 6 stores electrical energy to provide the electrical energy required for the initial start-up of the on-site hydrogen production fuel cell module 1. The fuel cell module 14 can replenish the electrical energy lost by the lithium battery module 6, and at the same time provide power to the liquid-cooled server 3 through the PDU 5. The control unit 15 is used to coordinate the collaborative work between the modules.

[0040] Furthermore, the control unit coordinates the power supply relationship between the lithium battery module, fuel cell unit, and liquid-cooled server. The fuel cell unit serves as the primary power source, while the lithium battery module acts as a backup and transitional power source. When the backup power source is shut down, the primary power source is already in a stable power supply state.

[0041] The control unit determines the switching time and power supply time between the main power supply and the backup power supply based on the power consumption of each electrical device, thereby achieving energy saving.

[0042] like Figure 3 As shown, the on-site hydrogen production fuel cell module 1 includes: a fuel tank 11, a reforming reaction unit 12, a heat exchange unit 13, a fuel cell unit 14, a control unit 15, a compressor 16, and a throttle valve 17; the heat exchange unit 13 is a plate heat exchanger.

[0043] The fuel tank 11 is used to store liquid alcohol solution and provides liquid alcohol and air to the reforming reaction unit 12 through a built-in liquid pump and air pump. The reforming reaction unit 12 uses liquid alcohol solution and air to generate syngas containing hydrogen through an autothermal reforming reaction of alcohols, and provides hydrogen to the fuel cell unit 14. The heat exchange unit 13 is used to cool the syngas generated by the reforming reaction unit 12 to make its temperature reach the reaction requirements of the fuel cell. The fuel tank 11 also provides the air required for the reaction of the fuel cell unit 14 through a built-in air pump. The fuel cell unit 14 uses hydrogen oxidation reaction to generate direct current. The fuel cell unit 14 adopts a proton exchange membrane fuel cell.

[0044] The liquid alcohol pump port 1101 of the fuel tank 11 is connected to the liquid alcohol inlet 1201 of the reforming reaction unit 12, the first air pump port 1102 is connected to the reforming reaction air inlet 1202, and the second air pump port 1103 is connected to the fuel cell air inlet 1403; the syngas outlet 1204 is connected to the first inlet 1301 of the heat exchange unit, the combustion reaction hydrogen inlet 1203 is connected to the second outlet 1304 of the heat exchange unit, the first outlet 1302 of the heat exchange unit is connected to the fuel cell hydrogen inlet 1402, and the second inlet 1303 of the heat exchange unit is connected to the fuel cell hydrogen outlet 1401. The above connections constitute the reforming reaction hydrogen production loop of the system.

[0045] Figure 4 This is a schematic diagram of the reforming reaction unit 12, which includes an upper cover 1205, a preheating plate 1206 with a refrigerant inlet 1217 and a refrigerant outlet 1207, an evaporation plate 1208, a combustion plate 1209, a reforming reaction plate 1210, and a carbon monoxide removal plate 1211. The preheating plate 1206 heats the liquid alcohol solution and air. The reaction chamber within the evaporation plate 1208 vaporizes the liquid alcohol solution and mixes it with air. The combustion plate 1209 burns unreacted hydrogen in the fuel cell, providing heat for the reactions in the evaporation plate 1208 and the reforming reaction plate 1210. The reforming reaction plate 1210 reacts the alcohol and air mixture to generate syngas containing hydrogen. The carbon monoxide removal plate 1211 reduces the carbon monoxide content in the syngas to meet the reaction requirements of the fuel cell unit 14.

[0046] The evaporation plate 1208, combustion plate 1209, reforming reaction plate 1210, and carbon monoxide removal plate 1211 are processed with reaction chambers. Foam metal or microchannel arrays are placed in the reaction chambers and coated with reaction catalysts. The preheating plate 1206 is processed with heat exchange chambers and microchannel arrays are processed in the heat exchange chambers.

[0047] A preheating plate 1206, an evaporation plate 1208, a combustion plate 1209, a reforming reaction plate 1210, and a carbon monoxide removal plate 1211 are connected in series via positioning screws 1214 to form a reaction unit. Multiple reaction units are stacked and locked together via an upper end cover 1205, a lower end cover 1213, and multiple connecting screws 1215 to form a reforming reaction module 12. The number of reaction units is determined according to the actual power used. The first reaction unit is locked to the upper end cover 1205 via positioning screws 1214. If there are more than one reaction unit, they are locked to the connecting plate 1212 via positioning screws 1214.

[0048] like Figure 1 , Figure 3 and Figure 4As shown, one side of the refrigerant distribution module 4 is connected to n liquid-cooled servers 3 via n (n≥1) cooling hoses 403. The liquid-cooled servers 3 are connected in parallel to the refrigerant distribution module 4. The refrigerant outlet 401 of the distribution unit on the refrigerant distribution module 4 is connected to the refrigerant inlet 1217 of the reforming reaction unit 12 in the on-site hydrogen fuel cell unit 1 via the first refrigerant pipe 201 and the compressor 16. The refrigerant outlet 1207 of the reforming reaction unit 12 is connected to one side of the heat exchange unit 13 via the second refrigerant pipe 19 after passing through the throttle valve 17. The other side of the heat exchange unit 13 is connected to the refrigerant inlet 402 of the distribution unit via the third refrigerant pipe 202. The above connections constitute the cooling loop of the system.

[0049] In this embodiment, the fuel tank 11 pumps the liquid alcohol solution into the reforming reaction unit 12 through the liquid alcohol pump port 1101 and the liquid alcohol inlet 1201, and at the same time pumps air into the reforming reaction unit 12 through the first air pump port 1102 and the reforming reaction air inlet 1202.

[0050] Figure 5 It is a reactant flow path within a single reforming reaction unit. There are two reactant paths within the reforming reaction unit 12: a reforming reaction path and a combustion reaction path. Liquid alcohol solution and air enter the reforming reaction unit 12. After passing through the reforming reaction path, the liquid alcohol solution absorbs heat and vaporizes in the evaporation plate 1208, mixing with air to form a mixed gas. The initial heat of the reaction is provided by the preheating plate 1206. The mixed gas then enters the reforming reaction plate 1210. Under the action of high temperature and catalyst, the mixed gas undergoes an autothermal reforming reaction and is transformed into a hydrogen-containing synthesis gas. The synthesis gas then enters the carbon monoxide removal plate 1211. After the action of catalyst, the carbon monoxide content in the synthesis gas is reduced and discharged from the composite reforming reaction unit 12.

[0051] Synthesis gas enters heat exchange unit 13 through synthesis gas outlet 1204 and heat exchange unit first inlet 1301. In heat exchange unit 13, the heat of synthesis gas is carried away by the refrigerant, the temperature of synthesis gas decreases, and it enters fuel cell unit 14 through heat exchange module first outlet 1302 and fuel cell hydrogen inlet 1402.

[0052] Simultaneously, the fuel tank 11 pumps air into the fuel cell unit 14 through the second air pump port 1103 and the fuel cell air inlet 1403. Hydrogen undergoes an oxidation reaction within the fuel cell unit 14, generating electricity to power the server rack. Some unreacted hydrogen enters the heat exchange unit 13 for cooling via the fuel cell hydrogen outlet 1401 and the second inlet 1303. The cooled hydrogen then enters the reforming reaction unit 12 via the second outlet 1304 of the heat exchange unit and the combustion reaction hydrogen inlet 1203.

[0053] In the reforming reaction unit 12, hydrogen enters the combustion plate 1209 through the combustion reaction line. Under the action of the catalyst, the hydrogen is burned, providing heat for the reaction in the evaporation plate 1208 and the reforming reaction plate 1210. Subsequently, the reaction gas is discharged from the reforming reaction unit 12.

[0054] At the same time, the cooling system operates in conjunction with the reforming reaction hydrogen production system. Figure 6 The principle of a liquid-cooled cabinet cooling system was demonstrated. For example... Figure 1 , Figure 4 , Figure 6 As shown, compressor 16 compresses low-pressure gaseous refrigerant through refrigerant inlet 1217 into preheating plate 1206 in reforming reaction unit 12. In preheating plate 1206, the low-pressure gaseous refrigerant is compressed into high-pressure liquid refrigerant and releases heat, which heats the gas mixture. Subsequently, the high-pressure liquid refrigerant in preheating plate 1206 flows out of reforming reaction unit 12 through refrigerant outlet 1207 and flows through second refrigerant pipe 19 to heat exchange unit 13. During this process, the pressure decreases as it flows through throttle valve 17, and the low-pressure liquid refrigerant flows into the heat exchange unit. In unit 13, a portion of the low-pressure liquid refrigerant absorbs heat from the syngas and vaporizes as it flows through the heat exchange unit 13, cooling the syngas. It then flows out of the heat exchange unit 13 with the remaining liquid refrigerant. Subsequently, the remaining low-pressure liquid refrigerant flows into the cold plate inside the liquid-cooled server 3 through the third refrigerant pipe 202. Inside the cold plate, the remaining low-pressure liquid refrigerant absorbs heat from the liquid-cooled server 3 and vaporizes. All the liquid refrigerant vaporizes into low-pressure gaseous refrigerant, which is then drawn into the compressor 16 to complete one cooling cycle.

[0055] This invention avoids the safety hazards of hydrogen storage devices in traditional fuel cell systems by using on-site hydrogen production technology, reduces the server system's dependence on electricity, and achieves server liquid cooling through a heat pump system, making full use of the waste heat generated by the server and enhancing the layout flexibility of server racks for edge computing and other scenarios.

[0056] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the embodiments described above. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
