[0051] In this embodiment, the pod is 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 (such as 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 cogeneration method may include steps S10 to S40. The above steps may be described in detail below:

[0052] Step S10, based on the operation instruction of the power unit 05, obtain the temperature control demand of the first electrical appliance 51 and the first ratio of the reaction medium. The reaction medium is water and methanol input into the hydrogen production unit 02 by the storage unit 01. 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 requirement, obtain the second ratio of the cooling medium. The cooling medium is a mixed solution of water and methanol input into the cooling unit 04 by the storage unit 01. The second ratio is the ratio of methanol to water in the cooling medium. Thus, the ratio of water to methanol in the cooling medium supplied by the storage unit 01 is determined according to the temperature control requirement of the first electrical appliance 51, so that the cooling medium can cool the first electrical appliance 51 to a set temperature range to ensure that the first electrical appliance 51 works normally.

[0054] Step S30 : Based on the second ratio, the storage unit 01 supplies cooling medium to the cooling unit 04 .

[0055] Step S40, based on the cooling medium and the first ratio supplied by the storage unit 01 to the cooling unit 04, the storage unit 01 is controlled to supply the reaction medium to the hydrogen production unit 02 at a third ratio. Among them, the ratio of the solution after the cooling medium of the second ratio and the reaction medium of the third ratio are mixed is within the set range of the first ratio. Thereby, 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] Step S31 : Based on the second ratio, the storage unit 01 supplies cooling medium to the cooling unit 04 at a first flow rate.

[0058] Step S32 , based on the storage unit 01 supplying 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 fact that the real-time temperature of the first electrical appliance 51 is greater than the temperature threshold within the temperature control time range, the storage unit 01 is controlled to supply the cooling medium to the cooling unit 04 at a second flow rate. The first flow rate is less than the second flow rate. In the case of determining the ratio of methanol and water in the cooling medium, when the real-time temperature of the first electrical appliance 51 exceeds the temperature threshold, it means that the first electrical appliance 51 has generated a large amount of heat and urgently needs to be dissipated. At this time, the flow rate of the cooling medium is increased in proportion through the storage unit 01, so that the cooling unit 04 can quickly take away the heat of the first electrical appliance 51, ensuring that the first electrical appliance 51 is cooled to the required temperature within the temperature control time range, so as to ensure the normal operation of the first electrical appliance 51.

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

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

[0062] Step S12, based on the second battery 33 supplying power to the second electrical appliance 52, obtaining a first ratio of the reaction medium, wherein the reaction medium is water and methanol input into the hydrogen production unit 02 by the storage unit 01. 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] Step S13: Based on the first ratio, the material 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] Step S14: Based on the reaction medium supplied from the material storage unit 01 to the hydrogen production unit 02, 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] Step S16, based on the temperature of the combustion chamber 22 reaching the set temperature range and the output voltage of the first battery 31 reaching the set voltage range and maintaining for the set time, the second battery 33 stops supplying power to the second electrical appliance 52, the first heater 25, and the second heater 26, and the first battery 31 supplies power to the power unit 05. At this time, the hydrogen production reaction in the hydrogen production unit 02 is close to being stable, and the hydrogen production unit 02 can realize self-supply of heat energy for reaction through the combustion chamber 22, reducing resource waste.

[0067] Step S17: Based on the power supply of the first battery 31 to the power unit 05 and the flight requirements of the aircraft, an operation instruction is issued to the first electrical appliance 51 of the power unit 05. The first electrical appliance 51 may be a high-power device such as a laser transmitter or a radar, and the rated power of the first electrical appliance 51 is greater than the rated power of the second electrical appliance 52.

[0068] Step S18: acquiring the temperature control requirement of the first electrical appliance 51 based on the operation 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 cogeneration method may further include:

[0070] Step S181, based on the operation instruction of the first electrical appliance 51, the first battery 31 and the second battery 33 jointly supply power to the power unit 05. Since the rated power of the first electrical appliance 51 is relatively large, the first battery 31 is a hydrogen fuel cell, and it takes a certain reaction time for the first battery 31 to increase the 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 unit 05, thereby reducing the impact on the aircraft.

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

[0072] Step S151, based on the second battery 33, the first heater 25 and the second heater 26 are powered, the vaporized reaction medium enters the reaction chamber 21 to react and obtain hydrogen to be transported to the first battery 31 of the power generation unit 03, and the air supply machine 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, and then transported to the reaction chamber 21 to react and produce hydrogen, so that the first battery 31 can react and convert into electrical energy.

[0073] Step S152, based on the hydrogen being transported to the first battery 31 and the air supply machine 35 supplying air to the first battery 31, the residual hydrogen after the reaction in the first battery 31 is discharged into the combustion chamber 22 of the hydrogen production unit 02 for combustion, and the first tail gas and the second tail gas are discharged into the heat exchanger 27 of the hydrogen production unit 02. Among them, the first tail gas is the excess gas generated after the reaction in the first battery 31. The second tail gas is the gas generated by combustion in the combustion chamber 22. By utilizing the residual hydrogen for combustion and then recovering the heat energy in the first tail gas and the second tail gas, sufficient heat energy can be provided for the hydrogen production reaction of the hydrogen production unit 02, which greatly reduces energy waste and reduces costs.

[0074] 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, based on the first tail gas and the second tail gas flowing through the heat exchanger 27, the separator 16 of the storage unit 01 separates the water in the first tail gas and the second tail gas and transports it to the water tank 13 of the storage unit 01. Thus, water circulation can be achieved to a certain extent, the water in the first tail gas and the second tail gas can be recycled, the water consumption can be reduced, and the cost can be reduced.

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

[0078] Step S41, based on the storage unit 01, the cooling medium is supplied to the cooling unit 04, and the spray cooling chamber 43 of the cooling unit 04 cools the first electrical appliance 51. In the spray cooling chamber 43, for different temperature control requirements of the first electrical appliance 51, temperature control cooling can be performed by adjusting different flow ratios of methanol and water. After determining the temperature control requirements and the ratio of methanol and water, the flow rates of methanol and water can be adjusted in equal proportions to ensure that the heat transferred by the first electrical appliance 51 is quickly taken away.

[0079] Step S42, the first electrical appliance 51 is cooled based on the spray cooling chamber 43, and the liquid cooling medium flows through the first channel 44 and the first evaporation chamber 23 to the reaction chamber 21 in sequence, and the gaseous cooling medium flows through the second channel 45 to the reaction chamber 21. By utilizing the heat transferred by the first electrical appliance 51 to gasify part of the cooling medium, the liquid cooling medium is recovered and input into the first evaporation chamber 23 for vaporization, so that the cooling medium can be transported to the reaction chamber 21 to participate in the hydrogen production reaction, thereby reducing resource waste and reducing the consumption of methanol and water.

[0080] Step S43 , based on the cooling medium entering the reaction chamber 21 , obtaining the current ratio of methanol to water in the reaction chamber 21 .

[0081] Step S44, based on the current ratio and the first ratio of methanol and water in the reaction chamber 21, control 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 cooling medium and the third ratio of reaction medium are mixed 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 into the reaction chamber 21 by the storage unit 01 and the cooling medium input into the reaction chamber 21 by the cooling unit 04 can meet the ratio requirement of methanol and water required for the hydrogen production reaction after mixing, thereby ensuring that the hydrogen production unit 02 produces hydrogen normally and avoiding large fluctuations in the output power of the first battery 31.

The first heater 25 is arranged in the inner chamber of the first evaporation chamber 23, so that the vaporization of methanol in the first evaporation chamber 23 can be accelerated.
