[0014] Preferably, the circulation component includes an air collecting duct, and the air collecting duct is installed through the top of the wind box, an air collecting plate is installed on the top of the air collecting duct, a guide plate is installed on the top of the air collecting plate, a collecting plate is installed at one end of the guide plate, and the collecting plate is installed on the back of the equipment cabin, and the outer sides of the air collecting duct, the air collecting plate, the guide plate and the collecting plate are covered with a heat insulation plate, and an air outlet is opened through the back of the equipment cabin at the position corresponding to the collecting plate.

[0015] Preferably, a control module is provided inside the equipment compartment, and the control module includes a sensing unit and an execution unit; The sensing unit is used to sense the temperature of the chipset, while the execution unit is used to cool the chipset using liquid nitrogen and wind power; The sensing unit includes a temperature sensor disposed at the bottom of the placement plate; The execution unit includes a one-way valve arranged on the outside of the branch pipe, a heat exchanger and a stop valve arranged on the outside of the recovery pipe, and a fan arranged on the back of the equipment compartment. When the temperature sensor senses that the temperature of the chipset has risen, the temperature sensor transmits a start signal to the one-way valve, the heat exchanger, the stop valve and the fan through electrical components. The one-way valve and the stop valve are started to transport the liquid nitrogen inside the storage tank to the inside of the cooling tank through the transport pipe for cooling. The liquid nitrogen absorbs heat and reacts to generate ammonia and water, which are cooled through the heat exchanger and then recovered to the recovery tank through the recovery pipe. The fan is started for wind heat dissipation.

[0016] Preferably, a method for using an aircraft thermal management system based on jet impingement cooling is as follows: S1. First, the staff opens the one-way valve and the stop valve at the same time, so that the liquid nitrogen inside the storage tank enters the inside of the cooling tank, absorbs the heat inside the placement plate, and the liquid nitrogen absorbs the heat and decomposes into ammonia and water. The ammonia and water inside the cooling tank enter the inside of the recovery tank through the recovery pipe for storage; S2. Then the staff grabs the slide plate and moves it, so that the slide plate drives the inner tube to rotate inside the fixed tube, so that the inner tube drives the vent to move to a position facing the middle of the placement plate, and then installs the chipset between two adjacent placement plates, so that the placement plates absorb the heat inside the chipset through contact, thereby cooling the chipset; S3. The staff starts the fan to blow the air inside the bellows into the inside of the fixed tube, so that the air inside the fixed tube passes through the vents and holes and blows toward the chipset to cool the chipset. At the same time, the air contacts the capillary tube, causing the temperature to drop and become cold air, so that the cold air blows toward the chipset to improve the cooling effect of air cooling. S4. When liquid nitrogen enters the inner side of the transport pipe, the temperature of the transport pipe decreases, causing the air around the transport pipe to contact the transport pipe and condense into small water droplets that drip along the fiber rod to the inner side of the water collecting box. The fiber rod seals the partition through water, so that water can only move downward through the fiber rod. The water at the bottom of the partition cannot reach the top of the partition, so that the water at the top of the partition gradually decreases, reducing the condensation of water on the surface of the transport pipe and reducing the corrosion of water to the transport pipe; S5. The air enters the inner side of the equipment cabin, which increases the air pressure inside the equipment cabin. Under the action of the pressure, the air inside the equipment cabin enters the inner side of the purification box through the return air duct. The air first contacts the filter in the purification box, so that the filter filters out the larger dust in the air. The air passes through the electrostatic filter material, and the fine particles are adsorbed on the surface of the electrostatic filter material, so that the passing air is purified, reducing the contact between dust and the chipset. S6. At the same time, the air inside the equipment cabin moves upward to the location of the storage tank under the action of air pressure. The liquid nitrogen inside the storage tank will lower the temperature of the environment around the storage tank, so that the air dissipates heat and becomes cold air when passing around the storage tank. The cold air passes through the air outlet and enters the inside of the bellows under the action of air pressure. Then, the cold air enters the inside of the equipment cabin again under the action of the fan to cool the chipset, thereby improving the utilization of the cold air around the storage tank.

[0017] Preferably, in step S5, the following steps are also included: S51. The staff member grasps the handle and moves it upward, so that the handle drives the sealing plate and the sealing ring to move out of the purification box under the action of external force, and the sealing plate drives the electrostatic filter material to move out of the inner side of the purification box, so as to facilitate the cleaning of the electrostatic filter material; S52. The staff member grasps the rotating ring and rotates it, so that the rotating ring drives the threaded plate to rotate under the action of external force, so that the threaded plate moves away from the equipment cabin by utilizing the thread action with the round tube, and the threaded plate is moved out of the inner side of the round tube to release the seal of the round tube. Then, the staff member grasps the rotating ring and moves it away from the equipment cabin, so that the rotating ring drives the round plate and the rubber ring to move through the threaded plate and the connecting rod, so that the round plate and the rubber ring clean out the dust inside the round tube.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is equipped with an air cooling component, which can generate airflow by using a fan to confine liquid nitrogen at the ventilation holes through a thin tube, so that the air at the ventilation holes becomes cold air. The airflow passes through the cold air area and blows toward the chipset. By adjusting the direction of the ventilation port, the chipset can be accurately cooled to improve the heat dissipation effect.

[0019] 2. The present invention is equipped with a transport pipe. When liquid nitrogen enters the inner side of the transport pipe, the air around the transport pipe contacts the transport pipe and condenses into small water droplets attached to the outer side of the transport pipe. The small water droplets contact the fine mesh, which reduces the surface tension of the small water droplets. The small water droplets slide downward under the action of their own gravity and fall to the top of the partition. The fiber rods absorb water and get wet, so that the water inside the fiber rods forms water droplets at the bottom of the fiber rods and falls to the inner side of the corresponding leakage pipe. The water droplets pass through the leakage pipe and enter the inner side of the water collecting box. The fiber rods seal the partition with water, so that water can only move downward through the fiber rods. The water at the bottom of the partition cannot come to the top of the partition, so that the water at the top of the partition gradually decreases, thereby reducing the condensation of water on the surface of the transport pipe and reducing the corrosion of water to the transport pipe.

[0020] 3. The present invention is equipped with an equipment cabin, and air enters the inner side of the equipment cabin, so that the air pressure inside the equipment cabin increases, and the air inside the equipment cabin enters the inner side of the return air duct under the action of pressure, so that the air passes through the return air duct and contacts the surface of the leakage pipe, and condensed water passes through the inside of the leakage pipe to reduce the temperature of the leakage pipe. The air passing around the leakage pipe can cool the air, and the cooled air enters the inner side of the purification box, and the air first contacts the filter in the purification box, so that the filter filters out larger dust in the air, and the larger dust falls downward through the square tube and enters the inner side of the round tube, and the air passes through the electrostatic filter material, and the electrostatic filter material uses static electricity to attract and capture particles, and adsorbs fine particles on the surface of the electrostatic filter material, so that the air passing through is purified, and the purified air passes through the square hole and enters the inner side of the bellows, and enters the inner side of the equipment cabin under the action of the fan, so as to realize air circulation purification and reduce the contact between dust and the chipset.

[0021] 4. The present invention is equipped with an equipment cabin. The air inside the equipment cabin moves upward under the action of air pressure, so that the air moves to the location of the storage tank and contacts the surface of the storage tank. The liquid nitrogen inside the storage tank will lower the temperature of the environment around the storage tank, so that the air dissipates heat and becomes cold air when passing around the storage tank. The cold air passes through the air outlet under the action of air pressure and enters the inner side of the collecting plate. The cold air passes through the collecting plate and moves downward under the guidance of the guide plate and enters the inner side of the air collecting pipe, and then enters the inner side of the bellows through the air collecting pipe. Subsequently, the cold air enters the inner side of the equipment cabin again under the action of the fan to cool the chipset. The heat insulation board can prevent the cold air from absorbing heat during the movement, thereby improving the utilization of the cold air resources around the storage tank.

[0032] In this embodiment, air enters the inner side of the equipment cabin 1, so that the air pressure inside the equipment cabin 1 increases, and the air inside the equipment cabin 1 enters the inner side of the return air duct 27 under the action of pressure, so that the air passes through the return air duct 27 and contacts the surface of the leakage pipe 46, and condensed water passes through the inner side of the leakage pipe 46, so that the temperature of the leakage pipe 46 is reduced.

[0034] In this embodiment, the liquid nitrogen inside the cooling tank 9 enters the inner side of the liquid storage tank 60 through the through pipe 61, and the liquid nitrogen absorbs a large amount of heat through the cryogenic tube 58. When the air inside the cryogenic tube 58 contacts the inner wall of the cryogenic tube 58, the heat of the air is transferred to the liquid nitrogen through the cryogenic tube 58, so that the air inside the cryogenic tube 58 becomes cold air. Then the staff starts the fan 57, so that the fan 57 blows the air inside the bellows 24 into the inner side of the square box 55, so that the air passes through the square box 55 and enters the inner side of the cryogenic tube 58, so that the air inside the cryogenic tube 58 becomes cold air, and the cold air is blown to the chipset 54 through the blowing port 59 for cooling.

[0036] In this embodiment, when liquid nitrogen enters the inner side of the transport pipe 5, the temperature of the transport pipe 5 is reduced, so that the air around the transport pipe 5 contacts the transport pipe 5 and condenses into small water droplets attached to the outer side of the transport pipe 5. The small water droplets contact the fine mesh 41, so that the fine mesh 41 reduces the surface tension of the small water droplets. The small water droplets slide down along the surface of the transport pipe 5 under the action of their own gravity, so that the small water droplets fall to the top of the partition 44. The water on the top of the partition 44 gathers to the middle position of the partition 44 under the guidance of the guide ring 43. The water on the top of the partition 44 contacts the fiber rod 45, and the fiber rod 45 absorbs water and gets wet, so that the inner side of the fiber rod 45 Under the action of its own gravity, water moves downward along the fiber rod 45, so that water passes through the fiber rod 45 and forms water droplets at the bottom of the fiber rod 45 and falls to the inside of the corresponding leakage pipe 46. The water droplets pass through the leakage pipe 46 and enter the inside of the water collecting box 47, so that the moisture in the air at the top of the partition 44 moves to the bottom of the partition 44 through the fiber rod 45. The fiber rod 45 seals the partition 44 with water, so that water can only move downward through the fiber rod 45, and the moisture at the bottom of the partition 44 cannot reach the top of the partition 44, so that the moisture at the top of the partition 44 gradually decreases, thereby reducing the condensation of water on the surface of the transport pipe 5 and reducing the corrosion of the transport pipe 5 by water.

[0037] See also Figure 1 , Figure 4 and Figure 8 An embodiment of the present invention is as follows: an aircraft thermal management system based on jet impingement cooling, comprising a circulation component, the circulation component comprising an air collecting duct 48, and the air collecting duct 48 is installed through the top of the wind box 24, a wind collecting plate 49 is installed on the top of the air collecting duct 48, a guide plate 50 is installed on the top of the air collecting plate 49, a collecting plate 51 is installed at one end of the guide plate 50, and the collecting plate 51 is installed on the back of the equipment cabin 1, the outer sides of the air collecting duct 48, the air collecting plate 49, the guide plate 50 and the collecting plate 51 are covered with a heat insulation plate 52, and an air outlet 53 is opened through the back of the equipment cabin 1 at a position corresponding to the collecting plate 51.

[0038] In this embodiment, the air inside the equipment cabin 1 moves upward under the action of air pressure, so that the air moves to the position of the storage tank 4, so that the air contacts the surface of the storage tank 4, and the liquid nitrogen inside the storage tank 4 lowers the temperature of the surrounding environment of the storage tank 4, so that the air dissipates heat and becomes cold air when passing around the storage tank 4. The cold air continues to move toward the back under the action of air pressure, so that the cold air passes through the air outlet 53 and enters the inner side of the collecting plate 51. The cold air passes through the collecting plate 51 and moves downward under the guidance of the guide plate 50, so that the cold air passes through the inner side of the guide plate 50 and enters the inner side of the air collecting pipe 48 under the action of the air collecting plate 49, and enters the inner side of the bellows 24 through the air collecting pipe 48. Then, the cold air enters the inner side of the equipment cabin 1 again under the action of the fan 14 to cool the chipset 54. The heat insulation plate 52 can prevent the cold air from absorbing heat during the movement, thereby improving the utilization of the cold air around the storage tank 4.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the present invention: an aircraft thermal management system based on jet impingement cooling, comprising an equipment cabin 1, a control module is arranged inside the equipment cabin 1, and the control module comprises a sensing unit and an execution unit; The sensing unit is used to sense the temperature of the chipset 54, and the execution unit is used to dissipate the heat of the chipset 54 using liquid nitrogen and wind power; The sensing unit includes a temperature sensor 62 disposed at the bottom of the placement plate 3; The execution unit includes a one-way valve 7 arranged on the outside of the branch pipe 6 and a heat exchanger 11 and a stop valve 12 arranged on the outside of the recovery pipe 10, and a fan 14 arranged on the back of the equipment compartment 1. When the temperature sensor 62 senses that the temperature of the chipset 54 has increased, the temperature sensor 62 transmits a start signal to the one-way valve 7, the heat exchanger 11, the stop valve 12 and the fan 14 through electrical components. The one-way valve 7 and the stop valve 12 are started to transport the liquid nitrogen inside the storage tank 4 to the inside of the cooling tank 9 through the transport pipe 5 for cooling. The liquid nitrogen absorbs heat to generate ammonia and water, which are cooled through the heat exchanger 11 and then recovered to the recovery tank 13 through the recovery pipe 10. The fan 14 is started for wind heat dissipation.

[0040] Further, a method for using an aircraft thermal management system based on jet impingement cooling is as follows: S1. First, the staff opens the one-way valve 7 and the stop valve 12 at the same time, so that the liquid nitrogen inside the storage tank 4 enters the inner side of the cooling tank 9, absorbs the heat inside the placement plate 3, and the liquid nitrogen absorbs the heat and decomposes into ammonia and water. The ammonia and water inside the cooling tank 9 enter the inner side of the recovery tank 13 through the recovery pipe 10 for storage; S2, the staff then grabs the slide plate 21 and moves it, so that the slide plate 21 drives the inner tube 22 to rotate inside the fixed tube 17, so that the inner tube 22 drives the vent 23 to move to a position facing the middle of the placement plate 3, and then installs the chipset 54 between two adjacent placement plates 3, so that the placement plates 3 absorb the heat inside the chipset 54 through contact, and cool the chipset 54; S3, the staff starts the fan 14, so that the fan 14 blows the air inside the bellows 24 into the inside of the fixed tube 17, so that the air inside the fixed tube 17 passes through the vent 23 and the vent hole 18 and blows toward the chipset 54, so as to cool down the chipset 54. At the same time, the air contacts the capillary 19, so that the temperature is reduced and becomes cold air, so that the cold air is blown toward the chipset 54, so as to improve the cooling effect of air cooling; S4. When liquid nitrogen enters the inner side of the transport pipe 5, the temperature of the transport pipe 5 decreases, so that the air around the transport pipe 5 contacts the transport pipe 5 and condenses into small water droplets, which drip along the fiber rod 45 to the inner side of the water collecting box 47. The fiber rod 45 seals the partition 44 with water, so that water can only move downward through the fiber rod 45. The water at the bottom of the partition 44 cannot reach the top of the partition 44, so that the water at the top of the partition 44 gradually decreases, reducing the condensation of water on the surface of the transport pipe 5 and reducing the corrosion of water to the transport pipe 5; S5. The air enters the inner side of the equipment cabin 1, so that the air pressure inside the equipment cabin 1 increases, and the air inside the equipment cabin 1 enters the inner side of the purification box 26 through the return air duct 27 under the action of the pressure. The air first contacts the filter 33 in the purification box 26, so that the filter 33 filters out the larger dust in the air. The air passes through the electrostatic filter material 31, and the fine particles are adsorbed on the surface of the electrostatic filter material 31, so that the passing air is purified, and the contact between the dust and the chipset 54 is reduced; S6. At the same time, the air inside the equipment cabin 1 moves upward to the location of the storage tank 4 under the action of air pressure. The liquid nitrogen inside the storage tank 4 will lower the temperature of the environment around the storage tank 4, so that the air dissipates heat and becomes cold air when passing around the storage tank 4. The cold air passes through the air outlet 53 and enters the inside of the bellows 24 under the action of air pressure. Then, the cold air enters the inside of the equipment cabin 1 again under the action of the fan 14 to cool the chipset 54, thereby improving the utilization of the cold air around the storage tank 4.

[0041] Furthermore, in step S5, the following steps are also included: S51, the staff member grasps the handle 30 and moves it upward, so that the handle 30 drives the sealing plate 29 and the sealing ring 28 to move out of the purification box 26 under the action of external force, so that the sealing plate 29 drives the electrostatic filter material 31 to move out of the inner side of the purification box 26, so as to facilitate the cleaning of the electrostatic filter material 31; S52. The staff member grabs the rotating ring 37 and rotates it, so that the rotating ring 37 drives the threaded plate 36 to rotate under the action of external force, so that the threaded plate 36 uses the threaded action with the round tube 35 to move in the direction away from the equipment cabin 1, and moves the threaded plate 36 out of the inner side of the round tube 35 to release the seal of the round tube 35. Then, the staff member grabs the rotating ring 37 and moves it in the direction away from the equipment cabin 1, so that the rotating ring 37 drives the round plate 39 and the rubber ring 40 to move through the threaded plate 36 and the connecting rod 38, so that the round plate 39 and the rubber ring 40 clean out the dust on the inner side of the round tube 35.

[0042] The working principle of the present invention is as follows: before using the aircraft thermal management system based on jet impingement cooling, it is necessary to check whether the aircraft thermal management system based on jet impingement cooling has problems that affect its use. When the staff needs to use the aircraft thermal management system based on jet impingement cooling, they should first rotate the grab slide plate 21, point the vent 23 of the inner tube 22 toward the middle of the placement plate 3, place the chipset 54 on the top of the placement plate 3, and the temperature sensor 62 detects that the temperature is high, starts the one-way valve 7 and the stop valve 12, and the liquid nitrogen flows from the storage tank 4 through the placement plate 3 into the recovery tank 13. The fan 14 is started to allow the cold air to pass through the ventilation holes 18 and the ventilation holes 23 to dissipate the heat of the chipset 54. Part of the air on the inside of the equipment cabin 1 passes through the return air duct 27 and the purification box 26 to purify the air and enter the wind box 24. The air is then blown into the equipment cabin 1 by the fan 14 to form an air circulation. Another part of the gas in the equipment cabin 1 enters the wind box 24 through the air collecting port 48 to form a second air circulation, making full use of the cold air generated by the liquid nitrogen, and using the liquid nitrogen and wind power to cooperate to improve the heat dissipation effect.

The water at the bottom of the partition (44) cannot reach the top of the partition (44), so that the water at the top of the partition (44) gradually decreases, thereby reducing the condensation of water on the surface of the transport pipe (5) and reducing the corrosion of the water to the transport pipe (5); S5, air enters the inner side of the equipment cabin (1), causing the air pressure inside the equipment cabin (1) to increase, so that the air inside the equipment cabin (1) enters the inner side of the purification box (26) through the return air duct (27) under the action of the pressure, and the air first contacts the filter (33) in the purification box (26), so that the filter (33) filters out larger dust in the air, and the air passes through the electrostatic filter material (31), and fine particles are adsorbed on the surface of the electrostatic filter material (31), so that the air passing through is purified, and the contact between dust and the chipset (54) is reduced; S6. At the same time, the air inside the equipment cabin (1) moves upward to the location of the storage tank (4) under the action of air pressure. The liquid nitrogen inside the storage tank (4) lowers the temperature of the environment around the storage tank (4), causing the air to dissipate heat and become cold air when passing around the storage tank (4). The cold air passes through the air outlet (53) and enters the inside of the bellows (24) under the action of air pressure. Subsequently, the cold air enters the inside of the equipment cabin (1) again under the action of the fan (14) to cool the chipset (54), thereby improving the utilization of the cold air around the storage tank (4).

10. The method for using the aircraft thermal management system based on jet impingement cooling according to claim 9, characterized in that: In the step S5, the following steps are also included: S51, the staff member grasps the handle (30) and moves it upward, so that the handle (30) drives the sealing plate (29) and the sealing ring (28) to move out of the purification box (26) under the action of external force, so that the sealing plate (29) drives the electrostatic filter material (31) to move out of the inner side of the purification box (26), so as to facilitate the cleaning of the electrostatic filter material (31); S52. The staff member grasps the rotating ring (37) and rotates it, so that the rotating ring (37) drives the threaded plate (36) to rotate under the action of external force, so that the threaded plate (36) moves in a direction away from the equipment cabin (1) by means of the threaded action with the round tube (35), and moves the threaded plate (36) out of the inner side of the round tube (35), thereby releasing the seal on the round tube (35). Then, the staff member grasps the rotating ring (37) and moves it in a direction away from the equipment cabin (1), so that the rotating ring (37) drives the round plate (39) and the rubber ring (40) to move through the threaded plate (36) and the connecting rod (38), so that the round plate (39) and the rubber ring (40) clean out the dust inside the round tube (35).
