Description

Technical Field

[0001] This application relates to the field of aero-engine technology, and in particular to an integrated precooling device. Background Technology

[0002] In high-speed propulsion systems such as turbo-based combined cycle (TBCC) engines, a strong precooling system cools the high-temperature intake air to increase the turbine engine's operating speed limit and smoothly transition to ramjet engine mode. A strong precooling system typically consists of a precooler, a radiator, and a precooling medium circulation pump. The precooling medium absorbs heat from the high-speed airflow in the precooler and then releases this heat to a heat sink such as liquid hydrogen in the radiator, thereby continuously cooling the intake air.

[0003] Liquid hydrogen, due to its high heat sink properties, is often considered an ideal cooling medium. Precooling media are mainly divided into two categories: one is supercritical fluids such as hydrogen, helium, methane, and carbon dioxide; the other is liquid working fluids such as water, ethylene glycol, liquid metals, and heat transfer oils. Supercritical working fluids typically operate at pressures exceeding 10 MPa, posing significant safety risks, while liquid working fluids can operate under low-pressure conditions, offering high safety.

[0004] While liquid metals offer excellent thermal conductivity in liquid working fluids, large-flow circulation pumping of liquid metals suffers from limitations in terms of compactness and reliability. For example, traditional mechanical pumps with high-speed rotating components are prone to wear and corrosion in liquid metals; while electromagnetic pumps without rotating components are bulky and difficult to fit into the confined spaces of airborne equipment. Summary of the Invention

[0005] The summary of this application introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] This application provides an integrated precooling device, comprising:

[0007] A precooling mechanism, comprising a fluid channel and a first heat exchange channel, wherein a first fluid can flow through the fluid channel and a second fluid can flow through the first heat exchange channel, and the first fluid and the second fluid can exchange heat. A heat dissipation mechanism, comprising a heat dissipation cavity and a second heat exchange channel, wherein a third fluid can circulate through the heat dissipation cavity, and the first heat exchange channel is connected to the second heat exchange channel; and An electromagnetic drive mechanism includes an electric drive assembly and a magnetic drive assembly. The electric drive assembly is disposed on both sides of the second heat exchange channel along the width direction of the second heat exchange channel. The electric drive assembly can conduct current in the second fluid. The magnetic drive assembly is used to generate a magnetic field perpendicular to the second heat exchange channel. The current can interact with the magnetic field to generate a Lorentz force to drive the flow of the second fluid. The second fluid and the third fluid can exchange heat, so that the second fluid can continuously exchange heat with the first fluid.

[0008] The integrated precooling device according to this application includes a precooling mechanism, an electromagnetic drive mechanism, and a heat dissipation mechanism. The precooling mechanism includes a fluid channel and a first heat exchange channel. The fluid channel is capable of carrying a first fluid, and the first heat exchange channel is capable of carrying a second fluid. The first fluid and the second fluid can exchange heat. The heat dissipation mechanism includes a heat dissipation cavity and a second heat exchange channel. The heat dissipation cavity is capable of carrying a third fluid, and the first heat exchange channel and the second heat exchange channel are connected. The electromagnetic drive mechanism includes an electric drive assembly and a magnetic drive assembly. The electric drive assembly is disposed on both sides of the second heat exchange channel along the width direction of the second heat exchange channel. The electric drive assembly can conduct current in the second fluid. The magnetic drive assembly is used to generate a magnetic field perpendicular to the second heat exchange channel. The current can interact with the magnetic field to generate a Lorentz force to drive the flow of the second fluid. The second fluid and the third fluid can exchange heat, so that the second fluid can continuously exchange heat with the first fluid. In this way, through the cooperation of the electric drive component and the magnetic drive component, the second fluid can be directly driven to circulate within the first and second heat exchange channels. The first heat exchange channel of the precooling mechanism can be directly used as the drive channel for the second fluid. The second fluid can also exchange heat during its flow, achieving a reuse of heat exchange and pumping functions. This eliminates the need for an additional independent pump body, connecting pipes, and drive channel, reducing the system complexity and number of interfaces of the integrated precooling device, reducing the risk of fluid leakage and lowering maintenance costs. It avoids the bulky problem caused by the need for independent flow channels in split-type electromagnetic pumps, reducing the device's size and weight, and significantly reducing the overall space occupied by the integrated precooling device, allowing the device to be installed in… The confined space onboard ensures reliable circulation of large-flow liquid metal within a limited area. The reuse of heat exchange and pumping functions avoids the additional pressure drop and heat loss caused by piping connections in traditional split systems, improving overall heat exchange efficiency and achieving more efficient heat transfer. Simultaneously, the integrated precooling device fundamentally eliminates the high-speed rotating components of traditional mechanical pumps, avoiding wear and corrosion problems caused by rotating parts and enhancing the long-term operational reliability of the device. Furthermore, after the second fluid absorbs heat from the first fluid, it releases the heat to the third fluid, allowing the cooled second fluid to continuously cool the first fluid, improving energy utilization efficiency and ensuring the continuous and efficient operation of the integrated precooling device.

[0024] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0025] like Figure 1As shown, this application provides an integrated precooling device 1, which can be used in equipment such as aero-engines, variable cycle engines, hypersonic turbine-based combined power systems, and gas turbine regenerators.

[0026] The integrated precooling device 1 includes a precooling mechanism 10, which includes a fluid channel 11 and a first heat exchange channel 12. The fluid channel 11 and the first heat exchange channel 12 are adjacent to each other and spaced apart. The axial direction of the fluid channel 11 is parallel to the axial direction of the first heat exchange channel 12. For example, the precooling mechanism 10 includes a precooling shell 18 and a precooling partition. The precooling partition is connected to the precooling shell 18. Both the fluid channel 11 and the first heat exchange channel 12 are located inside the precooling shell 18, and the fluid channel 11 and the first heat exchange channel 12 are located on opposite sides of the precooling partition. The fluid channel 11 can be separated from the first heat exchange channel 12 by the precooling partition. Alternatively, the precooling mechanism 10 includes a first heat exchange pipe, which is hollow inside to form the first heat exchange channel 12. The fluid channel 11 can be separated from the first heat exchange channel 12 by the first heat exchange pipe. The embodiments of this application do not limit the specific manner in which the fluid channel 11 and the first heat exchange channel 12 are spaced apart.

[0027] A first fluid can flow inside the fluid channel 11, and a second fluid can flow inside the first heat exchange channel 12. The first fluid flows axially within the fluid channel 11. This application does not limit the specific manner in which the first fluid enters the fluid channel 11, nor does it limit the specific manner in which the second fluid enters the first heat exchange channel 12. Optionally, the first fluid can be air, and the fluid channel 11 can be a corresponding air channel layer. The second fluid can be liquid metal, and the first heat exchange channel 12 can be a corresponding liquid metal channel layer.

[0028] The first fluid and the second fluid can exchange heat. The temperature of the second fluid is lower than that of the first fluid, and the heat from the first fluid can be transferred to the second fluid. In this way, the liquid metal can absorb the heat transferred from the air, thus lowering the temperature of the air.

[0029] The precooling mechanism 10 includes multiple fluid channels 11 and multiple first heat exchange channels 12, all spaced apart. The fluid channels 11 and the first heat exchange channels 12 are arranged alternately. Preferably, the fluid channels 11 and the first heat exchange channels 12 have identical structures. The multiple fluid channels 11 and the multiple first heat exchange channels 12 are equidistantly arranged along the thickness direction of the cooling baffle, and are arranged alternately along the thickness direction of the cooling baffle. The thickness direction of the cooling baffle is perpendicular to the axial direction of the first heat exchange channels 12. Thus, the multiple fluid channels 11 and the multiple first heat exchange channels 12 increase the heat exchange area between the first fluid and the second fluid, improving the heat exchange efficiency between the first fluid and the second fluid, enabling the first fluid to quickly transfer heat to the second fluid, thereby accelerating the cooling of the first fluid.

[0030] In this embodiment, the precooling mechanism 10 can be a precooler, which is generally a plate-fin heat exchanger structure. The plate-fin structure of the precooler can be made of metal materials such as aluminum alloy or stainless steel to balance strength and corrosion resistance. The precooling shell 18 can be made of a non-conductive, non-metallic material to avoid electromagnetic leakage.

[0031] Intermittent corrugated fins are provided inside the fluid channel 11. These intermittent corrugated fins can control the pressure drop of the first fluid, effectively preventing the continuous accumulation of flow resistance; simultaneously, they increase the heat exchange area and enhance the heat exchange effect. By optimizing the height and spacing of the intermittent corrugated fins, the heat exchange effect and flow resistance can be effectively balanced. This application does not limit the height and spacing of the intermittent corrugated fins in its embodiments.

[0032] The first heat exchange channel 12 is internally equipped with pin-ribbed fins, which are connected to the heat exchange baffle. Optionally, both the pin-ribbed fins and the heat exchange baffle can be made of the same material. For example, both the pin-ribbed fins and the heat exchange baffle can be made of aluminum alloy or stainless steel. The pin-ribbed fins can be connected to the heat exchange baffle using welding processes such as diffusion welding to ensure that both have certain structural strength and thermal conductivity. In this way, the pin-ribbed fins can support the baffle to withstand the pressure difference between the first fluid and the second fluid, while ensuring internal connectivity within the same first heat exchange channel 12. This results in a more uniform temperature distribution of the second fluid within the same first heat exchange channel 12, enhancing the heat exchange effect of the second fluid and reducing flow resistance.

[0033] Among them, such as Figure 2As shown, the needle-rib structure fin is provided with multiple needle-rib members 17, which are arranged in an array. The needle-rib members 17 are solid structures that can connect to the upper and lower walls of the same first heat exchange channel 12, improving the structural strength and support performance of the needle-rib structure fin, increasing the heat exchange area, and enhancing the heat exchange effect. Optionally, the diameter of the needle-rib member 17 can be 0.5 mm, and the spacing between two adjacent needle-rib members 17 can be 2 mm. This application embodiment does not limit the specific diameter, spacing, and arrangement of the needle-rib members 17. The diameter, spacing, and other parameters of the needle-rib members 17 can be determined through simulation optimization to ensure that the needle-rib structure fin can provide sufficient support stiffness while reducing flow resistance, thus minimizing the pressure drop of the liquid metal flow.

[0034] The integrated precooling device 1 also includes a heat dissipation mechanism 30, which includes a heat dissipation cavity 33 through which a third fluid can flow. The third fluid can flow within the heat dissipation cavity 33. Optionally, the heat dissipation cavity 33 can be the internal space of a radiator, and the third fluid can be liquid hydrogen, which can be processed and converted into hydrogen gas to flow within the heat dissipation cavity 33.

[0035] The heat dissipation mechanism 30 also includes a second heat exchange channel, which is spaced apart from the heat dissipation cavity 33. The first heat exchange channel 12 and the second heat exchange channel are connected. The second heat exchange channel can circulate a second fluid. Optionally, a second heat exchange pipe is provided in the heat dissipation cavity 33, and the interior of the second heat exchange pipe is hollow to form a second heat exchange channel. The first heat exchange pipe and the second heat exchange pipe are fixedly connected so that the first heat exchange channel 12 and the second heat exchange channel are connected. The first heat exchange pipe and the second heat exchange pipe can be integrally formed.

[0036] The integrated precooling device 1 also includes an electromagnetic drive mechanism 20, which includes an electric drive assembly 21 and a magnetic drive assembly 22, with the electric drive assembly 21 and the magnetic drive assembly 22 spaced apart. Optionally, the electromagnetic drive mechanism 20 can be an electromagnetic pump.

[0037] The electric drive assembly 21 is disposed on both sides of the second heat exchange channel along the width direction of the second heat exchange channel, and the electric drive assembly 21 is capable of conducting current in the second fluid. The width direction of the second heat exchange channel is perpendicular to the axial direction of the second heat exchange channel. Since the second fluid is conductive, when the electric drive assembly 21 conducts current, the current can pass through the second fluid along the width direction of the second heat exchange channel to form a stable current path.

[0038] The magnetic drive assembly 22 is located outside the precooling mechanism 10 and is disposed within the heat dissipation mechanism 30. The magnetic drive assembly 22 generates a magnetic field perpendicular to the second heat exchange channel. Optionally, the magnetic drive assembly 22 can be disposed on both sides of the heat dissipation mechanism 30 along the height direction of the second heat exchange channel, so that the magnetic field generated by the magnetic drive assembly 22 can penetrate all the second heat exchange channels within the heat dissipation mechanism 30. The height direction of the second heat exchange channel is perpendicular to the width direction of the second heat exchange channel and perpendicular to the axial direction of the second heat exchange channel.

[0039] Based on the Lorentz force principle, the current flowing through the second fluid interacts with the magnetic field generated by the magnetic drive assembly 22, producing a Lorentz force along the axial direction of the second heat exchange channel, thereby driving the flow of the second fluid. The Lorentz force can drive the directional flow of the second fluid. The second fluid in the second heat exchange channel can flow along the axial direction of the second heat exchange channel.

[0040] In this way, the integrated precooling device 1 integrates the precooler, radiator, and electromagnetic pump together. The Lorentz force can directly drive the second fluid to flow in the second heat exchange channel, which is directly used as the driving channel for the second fluid. By replacing the rotating parts of the traditional mechanical pump with electromagnetic drive, there is no need to set up an additional independent pump body connecting pipeline and driving channel. This avoids the problem of bulky size caused by the need for independent flow channels in split electromagnetic pumps, reduces the system complexity and number of interfaces of the integrated precooling device 1, reduces the risk of fluid leakage, and lowers maintenance costs. At the same time, the integrated precooling device 1 also fundamentally eliminates the high-speed rotating parts of the traditional mechanical pump, avoiding the wear and corrosion problems caused by rotating parts, and improving the long-term operational reliability of the device.

[0041] The heat dissipation cavity 33 allows flow of a third fluid, while the second heat exchange channel allows flow of a second fluid, enabling heat exchange between the second and third fluids. The second fluid has a higher temperature than the third fluid, allowing its heat to be transferred to the third fluid, thus cooling the second fluid. The first heat exchange channel 12 is connected to the second heat exchange channel, allowing the second fluid in the second heat exchange channel to flow into the first heat exchange channel 12, enabling the cooled second fluid to exchange heat with the first fluid. The first fluid has a higher temperature than the second fluid, allowing its heat to be transferred to the second fluid, thus cooling the first fluid. The second fluid in the first heat exchange channel 12 can also flow into the second heat exchange channel, allowing the second fluid to transfer the absorbed heat to the third fluid. The second fluid circulates between the first and second heat exchange channels, ensuring continuous heat exchange between the second fluid and the first fluid, thereby continuously cooling the first fluid, improving energy efficiency, and ensuring the continuous and efficient operation of the integrated pre-cooling device 1.

[0042] In this way, the integrated precooling device 1 is designed as a single unit, allowing the second fluid to be directly driven to circulate within the precooling mechanism 1. This achieves an organic integration of heat exchange and electromagnetic drive functions. The flow path of the second fluid can be optimized according to heat exchange requirements, avoiding the additional pressure drop and heat loss caused by pipeline connections in traditional split systems. This is beneficial for improving overall heat exchange efficiency and achieving more efficient heat transfer. Simultaneously, the integration of heat exchange and electromagnetic drive functions significantly reduces the size and weight of the integrated precooling device 1, minimizing its overall space requirements. This allows the integrated precooling device 1 to meet airborne installation requirements, improving its structural compactness and operational reliability. It enables reliable circulation drive of high-flow-rate liquid metal within a limited space, which is of great significance for aero-engine applications that are extremely sensitive to space and weight constraints.

[0043] According to the integrated precooling device 1 of this application, there are precooling mechanism 10, electromagnetic drive mechanism 20 and heat dissipation mechanism 30. The precooling mechanism 10 includes a fluid channel 11 and a first heat exchange channel 12. The fluid channel 11 can flow a first fluid, and the first heat exchange channel 12 can flow a second fluid. The first fluid and the second fluid can exchange heat. The heat dissipation mechanism 30 includes a heat dissipation cavity 33 and a second heat exchange channel. The heat dissipation cavity 33 can flow a third fluid. The first heat exchange channel 12 is connected to the second heat exchange channel. The electromagnetic drive mechanism 20 includes an electric drive assembly 21 and a magnetic drive assembly 22. The electric drive assembly 21 is disposed on both sides of the second heat exchange channel along the width direction of the second heat exchange channel. The electric drive assembly 21 can conduct current in the second fluid. The magnetic drive assembly 22 is used to generate a magnetic field perpendicular to the second heat exchange channel. The current can interact with the magnetic field to generate a Lorentz force to drive the flow of the second fluid. The second fluid and the third fluid can exchange heat, so that the second fluid can continuously exchange heat with the first fluid. In this way, through the cooperation of the electric drive component 21 and the magnetic drive component 22, the second fluid can be directly driven to circulate within the first heat exchange channel 12 and the second heat exchange channel. The first heat exchange channel 12 of the precooling mechanism 10 can be directly used as the driving channel for the second fluid. The second fluid can also exchange heat during its flow, realizing the reuse of heat exchange and pumping functions. There is no need to set up an independent pump body, connecting pipelines and driving channels, which reduces the system complexity and number of interfaces of the integrated precooling device 1, reduces the risk of fluid leakage and reduces maintenance costs, avoids the problem of bulky size caused by the need for independent flow channels in split electromagnetic pumps, reduces the size and weight of the device, and significantly reduces the overall space occupied by the integrated precooling device 1, making the device... The ability to be installed in confined airborne spaces ensures reliable circulation of large-flow liquid metal within limited space. The reuse of heat exchange and pumping functions avoids the additional pressure drop and heat loss caused by pipeline connections in traditional split systems, which helps to improve overall heat exchange efficiency and achieve more efficient heat transfer. At the same time, the integrated precooling device 1 fundamentally eliminates the high-speed rotating parts of traditional mechanical pumps, avoiding wear and corrosion problems caused by rotating parts and improving the long-term operational reliability of the device. In addition, after the second fluid absorbs the heat from the first fluid, it releases the heat to the third fluid, so that the cooled second fluid can continuously cool the first fluid, improving energy utilization efficiency and ensuring that the integrated precooling device 1 can operate continuously and efficiently.

[0044] The magnetic drive assembly 22 includes at least two magnetic members 221, which are spaced apart and arranged opposite to each other. The at least two magnetic members 221 are located on opposite sides of the second heat exchange channel. Optionally, the at least two magnetic members 221 may be arranged on opposite sides of the second heat exchange channel along its height.

[0045] At least two magnetic components 221 are capable of generating a magnetic field perpendicular to the second heat exchange channel. Through lightweight design, the at least two magnetic components 221 can achieve a high magnetic field strength within a limited space and reduce the space occupied by the magnetic components 221, thereby further improving the structural compactness and operational reliability of the integrated precooling device 1. Optionally, both magnetic components 221 can be superconducting magnets, which can be wound with a high-critical-temperature rare-earth yttrium barium copper oxide (YBCO) coated conductor. The at least two magnetic components 221 are capable of generating a constant magnetic field with a strength of 2 T (Tesla).

[0046] The electromagnetic drive mechanism 20 also includes a power supply component for outputting electrical energy. The power supply component is electrically connected to the electric drive assembly 21. Optionally, the power supply component can be a drive power source.

[0047] like Figures 1 to 3 As shown, the electric drive assembly 21 includes at least two electrode members 211, which are disposed opposite to each other. The at least two electrode members 211 are spaced apart along the width direction of the second heat exchange channel, and are respectively disposed on both sides of the second heat exchange channel. Both electrode members 211 are electrically connected to the power supply assembly. Optionally, both electrode members 211 can be connected to the drive power supply via leads, thereby enabling electrical connection between the at least two electrode members 211.

[0048] When current is applied to at least two electrode components 211, the second fluid becomes conductive, and the at least two electrode components 211 can conduct current within the second fluid. The current flows through the second fluid along the width of the second heat exchange channel and interacts with a strong magnetic field perpendicular to the plane of the second heat exchange channel, generating a Lorentz force along the axial direction of the second heat exchange channel, driving the directional flow of the second fluid. Optionally, both electrode components 211 can be made of corrosion-resistant platinum-iridium alloy sheets. The two electrode components 211 are respectively a positive electrode and a negative electrode. When current is applied to both the positive and negative electrodes, the positive electrode can conduct current to the negative electrode through the second fluid.

[0049] The electromagnetic drive mechanism 20 may be provided with at least two electric drive components 21, which are spaced apart along the axial direction of the second heat exchange channel. Each of the at least two electric drive components 21 is connected to a power supply component, and adjacent electric drive components 21 are electrically insulated. Any electrode component 211 can be connected to the drive power supply via a lead wire, allowing the power supply component to independently apply current for segmented power supply. This segmented power supply reduces the operating voltage required for each electrode component 211, improving electrical safety. Simultaneously, by independently controlling the magnitude and direction of the current in each segment, the local Lorentz force distribution within the second heat exchange channel can be precisely adjusted, thereby regulating the speed and direction of the second fluid flow and ensuring the stable operation of the integrated precooling device 1.

[0050] The electromagnetic drive mechanism 20 also includes an insulating component 23, which is disposed between the pre-cooling partition and the electric drive component 21. Optionally, the insulating component 23 can be an insulating layer, which is an alumina ceramic coating with a thickness of about 0.1 mm, applied to the surface of the partition by plasma spraying to ensure good insulation performance between the electrode component 211 and the metal pre-cooling partition, preventing current bypass loss. Similarly, an insulating layer can also be provided between the electrode component 211 and the pre-cooling housing 18. The pre-cooling housing 18 can be made of a non-conductive non-metallic material to ensure the normal operation of the electric drive component 21 and the magnetic drive component 22, while preventing electromagnetic leakage. In this way, the insulation component 23 can prevent current leakage and effectively avoid current leakage to the outside of the precooling mechanism 10, thereby improving the safety performance of the integrated precooling device 1. At the same time, the insulation component 23 can keep at least two electrode components 211 in the second fluid for a long time, effectively preventing the electrode components 211 from corroding and failing. Furthermore, the insulation component 23 ensures that both the electric drive component 21 and the magnetic drive component 22 act precisely on the second fluid, so that the second fluid flows under the action of the Lorentz force, ensuring that the integrated precooling device 1 can operate stably for a long time.

[0051] The precooling mechanism 10 includes an air inlet 13, an air outlet 14, a liquid inlet 15, and a liquid outlet 16. The air inlet 13 and the air outlet 14 are located at both ends of the fluid channel 11, and the liquid inlet 15 and the liquid outlet 16 are located at both ends of the first heat exchange channel 12.

[0052] Both the air inlet 13 and the air outlet 14 are connected to the fluid channel 11. The first fluid can be delivered to the fluid channel 11 through the air inlet 13, and the first fluid in the fluid channel 11 can be discharged through the air outlet 14. The first fluid flows from the air inlet 13 to the air outlet 14.

[0053] For example, the integrated precooling device 1 can be used in a TBCC engine. When the integrated precooling device 1 is running, the first fluid is drawn into the fluid channel 11 through the air inlet 13. The fluid channel 11 then delivers the heat-exchanged first fluid to the TBCC engine through the air outlet 14 to ensure the normal operation of the TBCC engine.

[0054] Both the inlet 15 and the outlet 16 are connected to the first heat exchange channel 12. The inlet 15 is used to transport the second fluid into the first heat exchange channel 12, and the outlet 16 is used to discharge the second fluid from the first heat exchange channel 12. The second fluid flows from the inlet 15 to the outlet 16. Simultaneously, both the inlet 15 and the outlet 16 are connected to the second heat exchange channel. The second fluid in the first heat exchange channel 12 flows into the second heat exchange channel through the outlet 16, and the second fluid in the second heat exchange channel flows into the first heat exchange channel 12 through the inlet 15. Optionally, the inlet 15 can be the inlet 15 of the first heat exchange pipe, and the outlet 16 can be the outlet 16 of the first heat exchange pipe. In this way, the second fluid can circulate, allowing it to alternately exchange heat with the first and third fluids, thereby continuously cooling the first fluid.

[0055] In this design, the liquid inlet 15 is closer to the air outlet 14 than the liquid outlet 16. When the second fluid flows in the first heat exchange channel 12, the flow direction of the first fluid is opposite to that of the second fluid. This allows the first and second fluids to exchange heat through counter-current heat exchange, improving heat exchange efficiency. Furthermore, the low-temperature second fluid flows into the first heat exchange channel 12 from the liquid inlet 15, first exchanging heat with the first fluid near the air outlet 14, and then with the first fluid near the air inlet 13. This effectively reduces the temperature difference between the first fluid at the air inlet 13 and the air outlet 14, and simultaneously reduces the temperature difference between the second fluid at the liquid inlet 15 and the liquid outlet 16. This results in a smoother temperature change between the first and second fluids, preventing malfunctions caused by excessive local temperature differences. Consequently, a better pre-cooling effect can be achieved with the same heat exchange area, ensuring the stable operation of the integrated pre-cooling device 1.

[0056] The heat dissipation mechanism 30 also includes a liquid supply pipe 31 and a liquid outlet pipe 32. Both the liquid supply pipe 31 and the liquid outlet pipe 32 are hollow structures, and both are used to transport a third fluid. The liquid supply pipe 31 and the liquid outlet pipe 32 are connected, and the liquid supply pipe 31 can transport the third fluid to the liquid outlet pipe 32.

[0057] Specifically, the liquid supply pipeline 31 is connected to an external liquid supply device, which can deliver a third fluid into the liquid supply pipeline 31, allowing the third fluid to circulate inside the liquid supply pipeline 31. Optionally, the external liquid supply device can be an onboard liquid hydrogen storage tank, and the liquid supply pipeline 31 can be a liquid hydrogen cooling pipeline, through which liquid hydrogen in the onboard liquid hydrogen storage tank can be delivered to the liquid hydrogen cooling pipeline and output externally.

[0058] The magnetic drive assembly 22 also includes a Dewar structure, with the magnetic component 221 located inside the Dewar structure. The Dewar structure can seal the superconducting magnet inside. Optionally, the magnetic drive assembly 22 also includes a low-heat-leakage support component, which is connected to the pre-cooling housing 18 and can also be connected to the Dewar structure. The low-heat-leakage support component can be a fiberglass bracket to provide structural strength and thermal insulation properties, thereby reducing heat conduction loss.

[0059] Both the supply pipe 31 and the outlet pipe 32 can be inserted into the Dewar structure. The supply pipe 31 is connected to the outlet pipe 32 through the interior of the Dewar structure, allowing the supply pipe 31 to deliver the third fluid to the outlet pipe 32. The interior of the Dewar structure is connected to the supply pipe 31, enabling the third fluid to be delivered into the interior of the Dewar structure and exchange heat with the magnetic component 221. Simultaneously, the interior of the Dewar structure is connected to the outlet pipe 32, allowing the third fluid, after heat exchange within the Dewar structure, to be delivered to the outlet pipe 32 and discharged externally. In this way, the airborne liquid hydrogen storage tank delivers liquid hydrogen to the inside of the Dewar structure through liquid hydrogen cooling pipelines, immersing and cooling the superconducting coil of the superconducting magnet to absorb the heat generated by the superconducting coil during operation. This provides a low-temperature environment for the superconducting magnet, ensuring its superconducting performance and stabilizing the magnetic field generated by the superconducting magnet. At the same time, after absorbing heat, the liquid hydrogen can vaporize into hydrogen gas and be discharged through the liquid outlet pipe 32, ensuring the normal operation of the integrated precooling device 1.

[0060] The liquid outlet pipe 32 is connected to the heat dissipation cavity 33, and the liquid outlet pipe 32 can deliver the third fluid to the heat dissipation cavity 33. The first heat exchange channel 12 is connected to the second heat exchange channel, and the second fluid in the first heat exchange channel 12 can flow into the second heat exchange channel. The second fluid in the second heat exchange channel can exchange heat with the third fluid in the heat dissipation cavity 33. The temperature of the second fluid is higher than that of the third fluid after exchanging heat with the magnetic component 221, so that the third fluid after exchanging heat with the magnetic component 221 can exchange heat with the second fluid to cool the second fluid. The heat-absorbing third fluid can flow into the engine's fuel supply system or the heat dissipation cavity 33 for further processing. For example, the heat-absorbing third fluid can be delivered to the engine's fuel supply system to participate in combustion. Or, the heat-absorbing third fluid can be delivered to the heat dissipation cavity 33 to cool the second fluid.

[0061] Preferably, when the second fluid flows into the second heat exchange channel, the flow direction of the second fluid is opposite to that of the third fluid. In this way, the second fluid and the third fluid exchange heat through countercurrent heat exchange, which improves heat exchange efficiency, accelerates the cooling of the second fluid, obtains a better pre-cooling effect, and ensures the stable operation of the integrated pre-cooling device 1.

[0062] In this way, by utilizing the cooling capacity of liquid hydrogen in stages and cooperating with the pre-cooling mechanism 10, the electromagnetic drive mechanism 20 and the heat dissipation mechanism 30, the energy is utilized in stages, improving the overall energy utilization rate. Furthermore, liquid hydrogen serves as both a superconducting coolant for the superconducting magnet and a pre-cooling heat sink for the liquid metal, reducing the need for additional cold sources, improving the overall energy efficiency and compactness of the system, and ensuring that the integrated pre-cooling device 1 can operate continuously and efficiently.

[0063] The integrated precooling device 1 integrates the precooler, radiator, and electromagnetic pump into one unit. Each first heat exchange channel 12 adopts a closed and independent structure. The electric drive component 21 and the magnetic drive component 22 cooperate to drive the second fluid to flow in the opposite direction to the first fluid in the closed layer. After absorbing heat, it enters the heat dissipation cavity 33 and exchanges heat with the third fluid in the opposite direction. Thus, the second fluid exchanges heat with the first and third fluids during the circulation process. In addition, the third fluid can exchange heat with the magnetic component 221 and the first fluid, realizing the cascade utilization of energy, improving energy utilization efficiency, reducing the need for an additional cold source for the integrated precooling device 1, further improving the overall energy efficiency and compactness of the system, and ensuring that the integrated precooling device 1 can operate continuously and efficiently.

[0064] The electromagnetic drive mechanism 20 also includes a shielding component 24, with the magnetic drive component 22 disposed inside the shielding component 24. The shielding component 24 is used to shield the magnetic field generated by the magnetic drive component 22 from the outside. Optionally, the shielding component 24 can be a magnetic shield. The magnetic shield is located outside the magnetic drive component 22 and can be made of a high-permeability alloy such as permalloy. High-permeability alloys have excellent magnetic properties, which can confine the magnetic field generated by the magnetic drive component 22 to the inside of the magnetic shield, reducing the risk of magnetic leakage in the integrated precooling device 1 and effectively preventing interference caused by magnetic leakage to the outside of the integrated precooling device 1.

[0065] Preferably, the precooling shell 18 of the precooling mechanism 10 can be made of a low-permeability material such as silicon carbide or ceramic. This effectively avoids adverse disturbances to the magnetic field distribution of the magnetic drive assembly 22 caused by the precooling mechanism 10, ensures that the Lorentz force can act uniformly and effectively on the second fluid, improves the flow efficiency of the second fluid, and also improves the stability of the second fluid flow.

[0066] Furthermore, the strong magnetic field environment generated by the magnetic drive assembly 22 can also be used to adapt to the functional requirements of other airborne equipment. For example, the strong magnetic field environment generated by the magnetic drive assembly 22 can directly provide the magnetic field environment required for the operation of airborne electromagnetic catapults, electromagnetic arresting gear, or particle accelerators, thus broadening the application scenarios and scope of application of the integrated precooling device 1.

[0067] The integrated precooling device 1 also includes a control mechanism 40, which comprises a monitoring component 41 and a control component 42, with the monitoring component 41 electrically connected to the control component 42. For example, the monitoring component 41 is used to monitor the operating status of the integrated precooling device 1 in real time. The monitoring component 41 can collect one or more parameters, such as the aircraft's flight Mach number, the aircraft's altitude, the temperature of the first fluid at the air inlet 13 and air outlet 14, the temperature of the second fluid at the liquid inlet 15 and liquid outlet 16, the temperature of the magnetic drive assembly 22, and the flow rate of the third fluid. All parameters collected by the monitoring component 41 can be converted into electrical signals and transmitted to the control component 42 for subsequent processing.

[0068] The control component 42 includes a first control element 421, which can output corresponding control commands based on the electrical signals transmitted by the monitoring component 41 to drive the corresponding execution components for regulation. Optionally, the first control element 421 can be a controller.

[0069] For example, the control component 42 can adjust the magnitude of the drive current through the first control member 421 to regulate the flow rate of the second fluid. The monitoring component 41 can collect engine operating parameters such as the aircraft's flight Mach number and flight altitude, as well as the temperature parameters of the first fluid at the air inlet 13 and air outlet 14 of the precooling mechanism 10 and the temperature parameters of the second fluid at the liquid inlet 15 and liquid outlet 16, and convert the above parameters into electrical signals and transmit them to the first control member 421.

[0070] When the aircraft's flight Mach number increases or the air intake temperature rises, the first control component 421 can dynamically adjust the drive current of the electromagnetic pump based on the electrical signal transmitted by the monitoring component 41, thereby adjusting the circulation flow rate of the second fluid in real time to meet the pre-cooling requirements under different operating conditions. Simultaneously, it can control the temperature fluctuation range of the first fluid at the air outlet 14 and the temperature fluctuation range of the second fluid at the liquid outlet 16 of the pre-cooling mechanism 10 within ±5K, ensuring that the temperatures of the first fluid at the air outlet 14 and the second fluid at the liquid outlet 16 are uniform and stable. For example, by increasing the average current through pulse width modulation (PWM), the drive current conducted by the electrode component 211 is increased, thereby increasing the circulation flow rate of the second fluid, improving heat exchange efficiency, enhancing the pre-cooling effect, and ensuring that the temperature of the first fluid at the air outlet 14 can be stably maintained within a preset range, thus enabling the integrated pre-cooling device 1 to stably deliver a first fluid of a certain temperature to the engine.

[0071] Furthermore, the first control component 421 can also regulate the flow velocity distribution of the second fluid along the width direction of the first heat exchange channel 12 by dividing and controlling the current conducted by each section of the electrode component 211. This allows the temperature fluctuations of the first fluid at the outlet 14 and the second fluid at the outlet 16 to be controlled within ±5K, ensuring that the temperature of the first fluid discharged from the outlet 14 and the temperature of the second fluid discharged from the outlet 16 are uniform and stable. For example, the control mechanism 40 can appropriately increase the current in areas with weaker local heat exchange to increase the flow velocity of the second fluid in those areas, preventing local temperature deviations from exceeding ±5K.

[0072] The control assembly 42 also includes a second control component 422, which is disposed in the liquid supply pipeline 31. The first control component 421 is electrically connected to the second control component 422, and the first control component 421 can adjust the flow rate of the third fluid through the second control component 422. Optionally, the second control component 422 can be a liquid hydrogen subcooling control valve. The liquid hydrogen subcooling control valve can adjust the flow cross-sectional area of ​​the third fluid in the liquid supply pipeline 31 by changing the valve opening, thereby achieving precise control of the third fluid supply flow rate.

[0073] For example, when the monitoring component 41 detects an increase in the temperature of the superconducting magnet or a rising trend in the temperature of the superconducting magnet, the first control component 421 can receive the electrical signal transmitted by the monitoring component 41 and output a control command to the second control component 422, driving the second control component 422 to increase the valve opening, thereby increasing the supply flow rate of the third fluid to enhance the cooling effect of the third fluid on the superconducting magnet, so that the temperature of the superconducting magnet is stable and can be stably maintained below the superconducting critical temperature, thereby ensuring that the superconducting magnet is always in a stable superconducting state and ensuring the stable operation of the integrated precooling device 1.

[0074] The control mechanism 40 also has fault diagnosis and protection functions. When the integrated precooling device 1 experiences abnormal conditions such as liquid metal leakage, power failure, or superconductivity failure, the control mechanism 40 can quickly cut off the electrode current and close the relevant valves, enter the safe shutdown mode, and issue an alarm signal to improve the safety of the integrated precooling device 1 operation.

[0075] For example, the monitoring component 41 includes a temperature measuring component 411 disposed on the magnetic component 221. The temperature measuring component 411 is used to monitor the temperature distribution at various points of the superconducting coil of the magnetic component 221 in real time. Optionally, the temperature measuring component 411 can be a fiber optic temperature sensor. The fiber optic temperature sensor is arranged inside the superconducting coil and can form a fiber optic temperature measuring grid inside the superconducting coil to monitor the temperature distribution at various points of the superconducting coil in real time.

[0076] When the temperature sensing component 411 detects an abnormal temperature rise in the superconducting magnet, it usually indicates that the superconducting magnet is about to quench or has entered the initial stage of quenching. The control mechanism 40 can immediately increase the supply flow of the third fluid or take other measures through the second control component 422 to quickly remove the heat generated by the operation of the superconducting magnet and suppress the further development of quenching. Alternatively, the integrated precooling device 1 is equipped with a magnet protection circuit for the magnetic drive assembly 22. The magnet protection circuit can be equipped with an energy transfer or discharge circuit on the circuit of the magnetic drive assembly 22 to quickly transfer or dissipate the energy generated during the operation of the magnetic drive assembly 22 and avoid damage caused by quenching of the magnetic drive assembly 22. Through the above measures, superconducting quenching caused by insufficient vaporization of liquid hydrogen can be effectively prevented, the stability and safety of the operation of the magnetic drive assembly 22 can be greatly improved, and the integrated precooling device 1 can be operated safely and stably.

[0077] Through integrated design, the volume and weight of the integrated precooling device 1 in this embodiment are significantly reduced. Compared to a traditional system consisting of a separate precooler and pump, it is estimated that the integrated precooling device 1 can reduce weight by more than 30% and volume by more than 20%. The second fluid is directly driven inside the precooling mechanism 10, avoiding long pipeline connections, reducing system pressure drop by about 15%, and improving heat exchange efficiency by about 10%. At the same time, by eliminating the mechanical pump, the potential for wear on rotating parts and seal leakage is eliminated, extending the mean time between failures (MTBF) of the integrated precooling device 1 and significantly increasing the maintenance cycle.

[0078] The integrated precooling device 1 of this application includes a precooling mechanism 10, an electromagnetic drive mechanism 20, and a heat dissipation mechanism 30. The precooling mechanism 10 includes a fluid channel 11 and a first heat exchange channel 12. The fluid channel 11 can flow a first fluid, and the first heat exchange channel 12 can flow a second fluid. The first fluid and the second fluid can exchange heat. The heat dissipation mechanism 30 includes a heat dissipation cavity 33 and a second heat exchange channel. The heat dissipation cavity 33 can flow a third fluid, and the first heat exchange channel 12 is connected to the second heat exchange channel. The electromagnetic drive mechanism 20 includes an electric drive assembly 21 and a magnetic drive assembly 22. The electric drive assembly 21 is disposed on both sides of the second heat exchange channel along the width direction of the second heat exchange channel. The electric drive assembly 21 can conduct current in the second fluid. The magnetic drive assembly 22 is used to generate a magnetic field perpendicular to the second heat exchange channel. The current can interact with the magnetic field to generate a Lorentz force to drive the flow of the second fluid. The second fluid and the third fluid can exchange heat, so that the second fluid can continuously exchange heat with the first fluid. In this way, the electric drive assembly 21 and the magnetic drive assembly 22 cooperate to directly drive the second fluid to flow within the first heat exchange channel 12. During the heat exchange process within the first heat exchange channel 12, the first heat exchange channel 12 of the precooling mechanism 10 also serves as the drive channel for the second fluid. The second fluid is directly driven to circulate by electromagnetic force, achieving the reuse of heat exchange and pumping functions. This eliminates the need for an additional independent pump body and drive channel, reducing the system complexity and number of interfaces of the integrated precooling device 1, reducing the risk of fluid leakage and lowering maintenance costs. It avoids the bulky problem caused by the need for independent flow channels in split electromagnetic pumps, reducing the device's size and weight, and significantly reducing the overall space occupied by the integrated precooling device 1. This allows the device to be installed in confined airborne spaces, ensuring the high-flow-rate liquid metal within limited space. The integrated precooling device 1 provides reliable cyclic drive; the reuse of heat exchange and pumping functions avoids the additional pressure drop and heat loss caused by pipeline connections in traditional split systems, which is conducive to improving overall heat exchange efficiency and achieving more efficient heat transfer; at the same time, the integrated precooling device 1 fundamentally eliminates the high-speed rotating parts of traditional mechanical pumps, avoiding wear and corrosion problems caused by rotating parts, and improving the long-term operational reliability of the device; in addition, after the second fluid absorbs the heat from the first fluid, it releases the heat to the third fluid, so that the cooled second fluid can continuously exchange heat with the first fluid, thereby continuously cooling the first fluid, realizing the cascade utilization of energy, improving energy utilization efficiency, reducing the demand for additional cold sources for the integrated precooling device 1, further improving the overall energy efficiency and compactness of the system, and ensuring that the integrated precooling device 1 can operate continuously and efficiently.

[0079] In summary, the integrated precooling device 1 not only improves overall performance but also effectively solves the problems of insufficient reliability and space constraints faced by traditional technologies in the circulation pumping of large-flow liquid metals, demonstrating broad application prospects in the fields of high-speed propulsion and airborne thermal management.
