Technical Field

[0001] The present invention relates to the technical field of aircraft pods, and in particular to an aircraft electric-cooling combined supply method and system. Background Art

[0002] Pods, devices that expand aircraft functionality, are widely used, such as electronic pods and laser pods. With the continuous development of electronic pods, energy consumption and heat flux have increased dramatically, placing increasingly stringent demands on pod energy supply and thermal management. At the same time, the increasing miniaturization of airborne pods places increasingly stringent restrictions on system size, weight, and energy consumption.

[0003] Existing energy supply technologies primarily draw energy from the aircraft, with thermal management achieved through a combination of heat storage and evaporation cycles. However, because pod energy consumption is intermittent, energy consumption and heat dissipation fluctuate widely, significantly impacting the onboard power grid and wasting significant resources.

[0051] In this embodiment, the pod is used as a device for expanding the functions of the aircraft. Since most pods use energy intermittently, the energy consumption and heat dissipation generated by them fluctuate greatly (for example, lasers and radars), their energy supply and thermal management are particularly important. Different pods require different working environment temperatures. How to achieve a balance between pod energy supply and heat dissipation becomes a problem that needs to be solved. To this end, this embodiment discloses a method for electric cooling combined supply of aircraft. Figure 1 As shown, the aircraft power-cooling combined power generation method may include steps S10 to S40. The above steps are described in detail below:

[0052] Step S10: Based on the operating instructions from the power consumption unit 05, the temperature control requirements of the first electrical consumer 51 and the first ratio of the reaction medium are obtained. The reaction medium is water and methanol input from the storage unit 01 to the hydrogen production unit 02. The first ratio is the ratio of methanol and water in the reaction medium in the reaction chamber 21 of the hydrogen production unit 02.

[0053] Step S20: Based on the temperature control requirements, a second ratio of the cooling medium is obtained. The cooling medium is a mixed solution of water and methanol supplied from the storage unit 01 to the cooling unit 04. The second ratio is the ratio of methanol to water in the cooling medium. The ratio of water to methanol in the cooling medium supplied from the storage unit 01 is determined based on the temperature control requirements of the first electrical appliance 51, so that the cooling medium can cool the first electrical appliance 51 to within a set temperature range, ensuring normal operation of the first electrical appliance 51.

[0054] In step S30 , the storage unit 01 supplies cooling medium to the cooling unit 04 based on the second ratio.

[0055] Step S40, based on the storage unit 01 supplying the cooling medium and the first ratio to the cooling unit 04, controls the storage unit 01 to supply the reaction medium to the hydrogen production unit 02 at a third ratio. The ratio of the solution after the second ratio of the cooling medium and the third ratio of the reaction medium is mixed is within the set range of the first ratio. As a result, the cooling medium can be discharged into the hydrogen production unit 02 after heat exchange with the first electrical appliance 51 to participate in the hydrogen production reaction, thereby reducing resource waste. At the same time, the storage unit 01 adjusts the ratio of water and methanol in the reaction medium supplied to the hydrogen production unit 02, so that the ratio of water and methanol in the solution after the reaction medium and the cooling medium are mixed in the reaction chamber 21 meets the ratio requirement of the hydrogen production reaction, thereby ensuring that the hydrogen production unit 02 produces hydrogen normally for subsequent use in the power generation unit 03 to generate electricity.

[0056] In this embodiment, step S30 may include:

[0057] In step S31 , based on the second ratio, the storage unit 01 supplies the cooling medium to the cooling unit 04 at a first flow rate.

[0058] Step S32 : Based on the storage unit 01 supplying the cooling medium to the cooling unit 04 at a first flow rate, the real-time temperature of the first electrical appliance 51 is obtained.

[0059] Step S33: Based on the real-time temperature of the first electrical appliance 51 being greater than a temperature threshold within the temperature control time range, control the storage unit 01 to supply cooling medium to the cooling unit 04 at a second flow rate. The first flow rate is less than the second flow rate. When the ratio of methanol to water in the cooling medium is determined, if the real-time temperature of the first electrical appliance 51 exceeds the temperature threshold, it indicates that the first electrical appliance 51 has generated a large amount of heat and urgently needs to dissipate it. At this time, the flow rate of the cooling medium is proportionally increased by the storage unit 01, allowing the cooling unit 04 to quickly remove the heat from the first electrical appliance 51, ensuring that the first electrical appliance 51 cools to the required temperature within the temperature control time range, thereby ensuring normal operation of the first electrical appliance 51.

[0060] In this embodiment, step S10 may include:

[0061] In step S11, based on the operation instruction of the power consumption unit 05, the second battery 33 of the power generation unit 03 supplies power to the second electrical device 52 of the power consumption unit 05. The second electrical device 52 can be a system device such as a pump, valve, or controller, and the second battery 33 can provide starting power to the system device.

[0062] In step S12, power is supplied to the second electrical device 52 by the second battery 33 to obtain a first ratio of the reaction medium. The reaction medium is water and methanol supplied from the storage unit 01 to the hydrogen production unit 02. The second ratio is the ratio of methanol to water in the reaction medium in the reaction chamber 21 of the hydrogen production unit 02.

[0063] In step S13, based on the first ratio, the storage unit 01 supplies the reaction medium to the hydrogen production unit 02, so that the hydrogen production reaction of the hydrogen production unit 02 can proceed normally.

[0064] In step S14, the storage unit 01 supplies the reaction medium to the hydrogen production unit 02, and the second battery 33 supplies power to the first heater 25 and the second heater 26 of the hydrogen production unit 02, thereby providing heat energy for the hydrogen production unit 02 to start the hydrogen production reaction.

[0065] Step S15: The second battery 33 supplies power to the first heater 25 and the second heater 26 to obtain the temperature of the combustion chamber 22 of the hydrogen production unit 02 and the output voltage of the first battery 31 of the power generation unit 03. The first battery 31 may be a high-temperature proton exchange membrane hydrogen fuel cell.

[0066] In step S16, when the temperature of combustion chamber 22 reaches the set temperature range and the output voltage of first battery 31 reaches the set voltage range and remains within the set time, second battery 33 stops supplying power to second electrical consumer 52, first heater 25, and second heater 26, and first battery 31 supplies power to power-consuming unit 05. At this point, the hydrogen production reaction in hydrogen production unit 02 approaches stability, and hydrogen production unit 02 can self-supply heat energy through combustion chamber 22 to proceed, reducing resource waste.

[0067] In step S17, based on the power supply from the first battery 31 to the power unit 05 and the flight requirements of the aircraft, an operating instruction is issued to the first electrical device 51 of the power unit 05. The first electrical device 51 can be a high-power device such as a laser transmitter or radar. The rated power of the first electrical device 51 is greater than the rated power of the second electrical device 52.

[0068] Step S18: obtaining a temperature control requirement of the first electrical appliance 51 based on the operating instruction of the first electrical appliance 51. The first electrical appliance 51 needs to operate within a set temperature range.

[0069] In this embodiment, the aircraft power-cooling combined supply method may further include:

[0070] In step S181, based on the operating instructions of the first electrical device 51, the first battery 31 and the second battery 33 jointly supply power to the power consumption unit 05. Since the rated power of the first electrical device 51 is relatively high and the first battery 31 is a hydrogen fuel cell, it takes a certain amount of time for the first battery 31 to increase its output power. The auxiliary power supply of the second battery 33 can avoid insufficient power supply from the power generation unit 03 to the power consumption unit 05, thereby reducing the impact on the aircraft.

[0071] In this embodiment, step S15 may include:

[0072] In step S151, the second battery 33 supplies power to the first heater 25 and the second heater 26. The vaporized reaction medium enters the reaction chamber 21, where it reacts and produces hydrogen, which is then transported to the first battery 31 of the power generation unit 03. The air supply 35 of the power generation unit 03 supplies air to the first battery 31. Methanol is heated to vaporization by the first heater 25 in the first evaporation chamber 23 of the hydrogen production unit 02, and water is heated to vaporization by the second heater 26 in the second evaporation chamber 24. The water is then transported to the reaction chamber 21 to react and produce hydrogen, thereby enabling the first battery 31 to convert the reaction into electrical energy.

[0073] In step S152, based on the hydrogen being delivered to the first cell 31 and the air supply unit 35 supplying air to the first cell 31, the residual hydrogen after the reaction in the first cell 31 is discharged into the combustion chamber 22 of the hydrogen production unit 02 for combustion, and the first and second tail gases are discharged into the heat exchanger 27 of the hydrogen production unit 02. The first tail gas is the excess gas produced after the reaction in the first cell 31. The second tail gas is the gas produced by combustion in the combustion chamber 22. By utilizing the residual hydrogen for combustion and then recovering the heat energy in the first and second tail gases, sufficient heat energy can be provided for the hydrogen production reaction in the hydrogen production unit 02, significantly reducing energy waste and lowering costs.

[0074] In step S153 , based on the residual hydrogen being discharged into the combustion chamber 22 for combustion and the first exhaust gas and the second exhaust gas being discharged into the heat exchanger 27 , the temperature of the combustion chamber 22 and the output voltage of the first battery 31 are obtained.

[0075] In this embodiment, step S15 may further include:

[0076] In step S154, as the first and second tail gases flow through the heat exchanger 27, the separator 16 of the storage unit 01 separates the water in the first and second tail gases and transports the water to the water tank 13 of the storage unit 01. This allows water circulation to be achieved to a certain extent, recycling the water in the first and second tail gases, reducing water consumption and lowering costs.

[0077] In this embodiment, step S40 may include:

[0078] In step S41, cooling medium is supplied to cooling unit 04 based on storage unit 01, and spray cooling chamber 43 of cooling unit 04 cools first electrical device 51. In spray cooling chamber 43, different flow ratios of methanol and water are adjusted to meet different temperature control requirements of first electrical device 51. After determining the temperature control requirements and the ratio of methanol to water, the flow rates of methanol and water are adjusted in equal proportions to ensure that heat transferred from first electrical device 51 is quickly removed.

[0079] In step S42, the spray cooling chamber 43 completes cooling of the first electrical consumer 51. The liquid cooling medium flows sequentially through the first channel 44 and the first evaporation chamber 23 to the reaction chamber 21, while the gaseous cooling medium flows through the second channel 45 to the reaction chamber 21. By utilizing the heat transferred from the first electrical consumer 51 to vaporize a portion of the cooling medium, the liquid cooling medium is recovered and fed into the first evaporation chamber 23 for vaporization, allowing the cooling medium to be transported to the reaction chamber 21 to participate in the hydrogen production reaction, thereby reducing resource waste and lowering methanol and water consumption.

[0080] Step S43 : Based on the cooling medium entering the reaction chamber 21 , the current ratio of methanol to water in the reaction chamber 21 is obtained.

[0081] In step S44, based on the current ratio of methanol and water in reaction chamber 21 and the first ratio, the storage unit 01 is controlled to supply the reaction medium to the hydrogen production unit 02 at a third ratio. The ratio of the solution formed by mixing the second ratio of cooling medium with the third ratio of reaction medium is within the set range of the first ratio. By controlling the storage unit 01 to reduce the ratio of methanol and water in the supplied reaction medium, the reaction medium input from the storage unit 01 to the reaction chamber 21 and the cooling medium input from the cooling unit 04 to the reaction chamber 21 are mixed to meet the methanol and water ratio requirements for the hydrogen production reaction, thereby ensuring normal hydrogen production by the hydrogen production unit 02 and avoiding large fluctuations in the power output of the first battery 31.

[0082] In this embodiment, this embodiment discloses an aircraft power-cooling cogeneration system, which can be applied to any of the aircraft power-cooling cogeneration methods in the above embodiments. Figure 2 As shown, the aircraft power-cooling combined supply system may include a fuel storage unit 01, a hydrogen production unit 02, a power generation unit 03, a cooling unit 04, and a power consumption unit 05. Fuel storage unit 01 includes a methanol tank 11, a methanol pump 12, a water tank 13, a water pump 14, and a diverter valve 15. The input of methanol pump 12 is connected to the output of methanol tank 11. The output of methanol pump 12 is connected to the input of diverter valve 15, facilitating the transfer of methanol stored in methanol tank 11 to hydrogen production unit 02. The input of water pump 14 is connected to the output of water tank 13, facilitating the transfer of water stored in water tank 13 to hydrogen production unit 02.

[0083] The hydrogen production unit 02 includes a reaction chamber 21, a combustion chamber 22, a first evaporation chamber 23, a second evaporation chamber 24, a first heater 25, a second heater 26, and a heat exchanger 27. The outer wall of the reaction chamber 21 abuts the inner wall of the combustion chamber 22. When methanol burns in the combustion chamber 22, it provides heat for the methanol-water reaction within the reaction chamber 21. The inner wall of the first evaporation chamber 23 abuts a portion of the outer wall of the combustion chamber 22, allowing the heat from the methanol combustion in the combustion chamber 22 to provide heat for the methanol vaporization within the first evaporation chamber 23. The inner wall of the second evaporation chamber 24 abuts a portion of the outer wall of the combustion chamber 22, allowing the heat from the methanol combustion in the combustion chamber 22 to provide heat for the water vaporization within the second evaporation chamber 24. The first and second evaporation chambers 23 and 24 are spaced apart. The first heater 25 is located within the interior of the first evaporation chamber 23, accelerating the vaporization of the methanol within the first evaporation chamber 23. The second heater 26 is disposed within the interior of the second evaporation chamber 24, accelerating the vaporization of water within the second evaporation chamber 24. The inner circumferential walls of the heat exchanger 27 abut the outer circumferential walls of the first and second evaporation chambers 23 and 24, respectively. This allows heat exchanged between the heat exchanger 27 and the first and second exhaust gases to be transferred to the first and second evaporation chambers 23 and 24, accelerating the vaporization of methanol and water. The output end of the diverter valve 15 is connected to the input end of the first evaporation chamber 23, the input end of the combustion chamber 22, and the input end of the reaction chamber 21, respectively. This allows the diverter valve 15 to control the flow of methanol into the first, combustion, and reaction chambers 23, 22, and 21, effectively distributing methanol usage and reducing methanol waste. The output end of the first evaporation chamber 23 is connected to the input end of the reaction chamber 21. The input end of the second evaporation chamber 24 is connected to the output end of the water pump 14. The output end of the second evaporation chamber 24 is connected to the input end of the reaction chamber 21. The output end of the combustion chamber 22 is connected to the input end of the heat exchanger 27. Through the above-mentioned arrangement, the heat energy generated during the operation of the hydrogen production unit 02 can be reasonably distributed and utilized, thereby reducing energy waste.

[0084] The input end of the power generation unit 03 is connected to the output end of the reaction chamber 21, so that the hydrogen produced by the reaction chamber 21 is input into the power generation unit 03 to react and convert into electrical energy.

[0085] The cooling unit 04 includes a first valve 41, a second valve 42, a spray cooling chamber 43, a first channel 44, and a second channel 45.

The output of the first battery 31 is connected to the input of the combustion chamber 22 and the input of the heat exchanger 27, respectively. This allows the residual hydrogen after the reaction in the first battery 31 to enter the combustion chamber 22 for combustion, and the first exhaust gas after the reaction can be input into the heat exchanger 27 for heat exchange, thereby achieving energy recovery and reducing resource consumption. The first battery 31, the first converter 32, and the busbar 36 are electrically connected in sequence. The second battery 33, the second converter 34, and the busbar 36 are electrically connected in sequence.
