Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0036] Aircraft include types such as eVTOL (Electric Vertical Takeoff and Landing), which combine the characteristics of helicopters and fixed-wing aircraft. They can achieve vertical take-off and landing and short-distance horizontal flight through electric drive. They are usually used for short-distance transportation within or between cities.

[0037] When these aircraft are in use, smoke may form unexpectedly inside them. Low-altitude aircraft like eVTOLs are unpressurized, making it difficult to exhaust such smoke. To ensure the high safety requirements of these aircraft, an air conditioning system with active smoke exhaust is required.

[0038] To this end, this application proposes a solution that combines active smoke exhaust functionality with the high safety requirements of aircraft. The aircraft provided in this application may include eVTOL, etc.

[0039] Figure 1 A schematic diagram of the structure of an aircraft 100 in one embodiment of the present application is shown, wherein Figure 1 The aircraft in is set to eVTOL type. Figure 1 The aircraft 100 includes a fuselage 108 and a wing assembly 109. The wing assembly 109 is installed on the fuselage 108. The wing assembly 109 may include an extending wing, a fixed rotor, a tilt rotor, etc., thereby providing flight power under the drive of a driving device such as an electric motor to achieve flight.

[0040] In addition, refer to Figure 2 and Figure 3 Aircraft 100 includes a loading area 101 and an air handling device 200. Loading area 101 can be understood as an area for carrying passengers or cargo. Air handling device 200 can provide a preset air environment for loading area 101. For example, it can be configured to change the state of the air in loading area 101 to achieve the preset air environment. For example, air handling device 200 includes an airflow driver 205, such as a blower, capable of suction or extraction, thereby changing the velocity state of the air in loading area 101. In further embodiments, air handling device 200 may also include a cooling module and a heating module to change the temperature state of the air in loading area 101.

[0041] In addition, the aircraft 100 is provided with an equipment air inlet 111 for allowing external air flow to enter and a first equipment air outlet 121 for allowing air flow to be discharged outwardly. The equipment air inlet 111 is connected to the load-bearing area 101; the input port of the airflow driver 205 is connected to the load-bearing area 101, and the output port of the airflow driver 205 is connected to the first equipment air outlet 121. The airflow driver 205 is configured to drive the air in the load-bearing area 101 to be discharged outwardly through the first equipment air outlet 121.

[0042] In this embodiment, the aircraft 100 is configured to include a carrying area 101 and an air treatment device 200, the aircraft 100 is provided with an equipment air inlet 111 for external airflow to enter and a first equipment air outlet 121 for airflow to be discharged outwardly, and the equipment air inlet 111 is connected to the carrying area 101; the air treatment device 200 includes an air flow driver 205, the input port of the air flow driver 205 is connected to the carrying area 101, and the output port of the air flow driver 205 is connected to the first equipment air outlet 121, and the air flow driver 205 is configured to drive the air in the carrying area 101 to be discharged outwardly through the first equipment air outlet 121, so that when smoke appears in the carrying area 101 of the aircraft 100, the smoke can be discharged from the carrying area 101 more quickly through the equipment air inlet 111, the air flow driver 205 and the first equipment air outlet 121. It can be understood that by starting the air flow driver 205, the smoke is actively discharged outward, thereby improving the smoke discharge efficiency and having a high-efficiency smoke exhaust function.

[0043] In addition, refer to Figure 2The aircraft 100 may further include a first equipment area 102. The first equipment area 102 is located at the rear side of the carrying area 101 along the direction of travel of the aircraft 100. Along the height direction of the aircraft 100, the first equipment area 102 is located on a side away from the belly of the aircraft 100. The carrying area 101 and the first equipment area 102 may be located in the fuselage 108. The fuselage 108 may be divided into a carrying compartment by a plate structure such as a partition. In this case, the carrying area is configured as the interior space of the carrying compartment. The belly of the aircraft 100 may be understood as the relatively lower portion when the aircraft 100 is traveling or docking normally. The height direction of the aircraft 100 may be understood as the corresponding up and down direction when the aircraft 100 is traveling or docking normally.

[0044] Reference Figure 2 In some embodiments, the aircraft 100 may further include a storage area 103 for storing items, which may be used to store luggage and other items; along the direction of travel of the aircraft 100, the storage area 103 is located on the rear side of the load-bearing area 101; along the height direction of the aircraft 100, the storage area 103 is located on the side of the first equipment area 102 toward the belly of the aircraft 100, which can be understood as the storage area 103 being located on the lower side of the first equipment area 102.

[0045] Reference Figure 2 In some embodiments, the aircraft 100 may further include a second equipment area 104. Along the direction of travel of the aircraft 100, the second equipment area 104 is located on a side of the carrier area 101 away from the first equipment area 102. This can be understood as the second equipment area 104 being located in front of the direction of travel of the aircraft 100. The aircraft 100 also includes a travel signal processing circuit. The travel signal processing circuit can be understood as a circuit for processing travel information of the aircraft 100. For example, the travel signal processing circuit can be included in an avionics computer. The travel signal processing circuit is located in the second equipment area 104, thereby increasing the distance between the travel signal processing circuit and the electrical components in the second equipment area 104, which helps to reduce the risk of electrical interference caused by the electrical components in the second equipment area 104 to the travel signal processing circuit, thereby improving the electrical safety of the aircraft 100.

[0046] Reference Figure 2 In some embodiments, the aircraft 100 can also form a third equipment area 105 on the side away from the belly of the aircraft 100 through a partition; it can be understood that the aircraft 100 can form the third equipment area 105 on the back through a partition, wherein the back of the aircraft 100 is arranged opposite to its belly, and the third equipment area 105 can also be understood as the top equipment area.

[0047] Reference Figure 2In some embodiments, the aircraft 100 may further include an equipment tail section 106, which is located on the rear side of the first equipment area 102 along the direction of travel of the aircraft 100. Furthermore, the aircraft 100 may further include a fourth equipment area 107, which is located on the side of the carrying area 101 facing the belly of the aircraft 100. This fourth equipment area can be understood as the belly equipment area.

[0048] Among them, it can be understood that the above-mentioned carrying area 101, the first equipment area 102, the storage area 103, the second equipment area 104, the third equipment area 105, the equipment tail section 106 and the fourth equipment area 107 can be separated into corresponding cabins by plate structures such as partitions and then formed through the internal space of the corresponding cabins, thereby improving the independence of each partition.

[0049] In which, at least a part of the above-mentioned air treatment device 200 is arranged in the first equipment area 102, including arranging part of the air treatment device 200 in the first equipment area 102, for example, arranging part or all of the refrigeration module, part or all of the heating module, and the air flow driver 205 in the first equipment area 102; of course, all of the air treatment devices 200 can also be arranged in the first equipment area 102.

[0050] In some embodiments, reference Figure 4 and Figure 5 The air handling unit 200 can be configured to include a first heat exchanger 201, a compressor 202, a second heat exchanger 203, and a throttle device 204, all connected via a refrigerant circuit 210. The first heat exchanger 201 is configured to exchange heat with the load compartment 101, and the second heat exchanger 203 is configured to exchange heat with the external environment of the aircraft 100. The refrigerant circuit 210 can be understood as a circuit for the flow of refrigerant, which can be a Freon, for example. The first heat exchanger 201 can be configured as an evaporator, thereby cooling the load compartment 101 by evaporating the refrigerant at the first heat exchanger 201 and absorbing heat. It is understood that the first heat exchanger 201 can be configured to communicate with the load compartment 101, thereby exchanging heat through the flow of air. However, in situations where the load compartment 101 is relatively small, the first heat exchanger 201 can also be isolated from the load compartment 101, with heat exchange occurring through heat conduction or other methods.

[0051] The second heat exchanger 203 can be configured as a condenser, so that the heat from the load-bearing area 101 is dissipated to the external environment by condensing the refrigerant at the second heat exchanger 203. In addition, the compressor 202 can be understood as a device that compresses gas and converts low-pressure gas into high-pressure gas, thereby providing the refrigerant with energy to release heat to a high-temperature environment (or absorb heat from a high-temperature environment during heating conditions), helping the refrigerant cycle to proceed smoothly. The compressor 202 includes but is not limited to a scroll compressor and a rotary compressor; the throttling device 204 can be understood as a device that converts high-pressure liquid into a low-temperature, low-pressure liquid. The throttling device 204 includes but is not limited to a capillary tube and an expansion valve. Among them, at least one of the first heat exchanger 201, the compressor 202, the second heat exchanger 203, and the throttling device 204 is located in the first equipment area 102. For example, the first heat exchanger 201 can be located in the first equipment area 102.

[0052] In this embodiment, the aircraft 100 is configured to include a carrying area 101, a first equipment area 102 and an air treatment device 200. Along the direction of travel of the aircraft 100, the first equipment area 102 is located on the rear side of the carrying area 101; along the height direction of the aircraft 100, the first equipment area 102 is located on the side away from the belly of the aircraft 100; the air treatment device 200 is configured to change the state of the air in the carrying area 101, and at least a portion of the air treatment device 200 is located in the first equipment area 102, which is conducive to enabling the air treatment device 200 to more fully utilize the space of the aircraft 100 and to reduce the volume of the aircraft 100; in addition, at least a portion of the air treatment device 200 is relatively far back and upward, which is conducive to increasing the distance between the portion of the air treatment device 200 and the electrical components located on the front side of the carrying area 101, which is conducive to reducing the risk of the portion of the air treatment device 200 causing electrical interference to the electrical components, thereby improving the electrical safety of the aircraft 100.

[0053] In some embodiments, the airflow driver 205, the first heat exchanger 201 and the load-bearing area 101 are connected through a heat exchange channel 220, and the airflow driver 205 is configured to output the airflow after heat exchange through the first heat exchanger 201 to the load-bearing area 101; for example, the first heat exchanger 201 can be configured to have a cooling function, so that the airflow driver 205 can output cold air to the load-bearing area 101; of course, the first heat exchanger 201 can also be configured to have a heating function, so that the airflow driver 205 can output warm air to the load-bearing area 101.

[0054] Reference Figure 3The heat exchange channel 220 may include an extension section 221 extending forward into the first equipment area 102. The extension section 221 communicates with the side of the load-bearing area 101 facing away from the belly of the aircraft 100. This can be understood as the extension section 221 being located at the back (i.e., top) of the aircraft 100. When the first heat exchanger 201 is located relatively rearward and upward, the extension section 221 communicates with the side of the load-bearing area 101 facing away from the belly of the aircraft 100. This helps reduce the overall length of the extension section 221, shortening the flow path of cooling or heating air, and improving heat transfer efficiency.

[0055] In some embodiments, reference Figure 3 The extended section 221 is provided with a first outlet 222 and at least one second outlet 223. The first outlet 222 is located forward of all second outlets 223 in the direction of travel of the aircraft 100. A front window 110 is provided at the front end of the aircraft 100 in the direction of travel of the aircraft 100. The first outlet 222 is located opposite the front window 110, while the second outlet 223 is connected to the loading area 101. If the first heat exchanger 201 has a heating function, heated air can be output to the front window 110 through the first outlet 222, thereby performing demisting on the front window 110. Of course, the heated or cooled air generated by the first heat exchanger 201 can also be output to the loading area 101 through the second outlet 223, thereby providing heated or cooled air to the loading area 101.

[0056] In some embodiments, reference Figure 3 and Figure 5 The air handling device 200 further includes a heater 206, which is connected to the heat exchange channel 220. Warm air generated by the heater 206 can be output to the front window 110 through the first outlet 222, thereby performing defogging on the front window 110. Of course, the warm air generated by the heater 206 can also be output to the support area 101 through the second outlet 223, thereby providing warm air to the support area 101. The heater 206 can be configured as a PTC heater including a PTC ceramic heating element (PTC, Positive Temperature Coefficient) and an aluminum tube.

[0057] In some embodiments, reference Figure 3 and Figure 5 The air handling device 200 further includes a filter structure 207, which is connected to the input port of the airflow driver 205 and is used to filter the airflow entering the airflow driver 205, thereby improving the cleanliness of the airflow. The filter structure 207 includes a filter element, etc.

[0058] It is understood that the first outlet 222 and the second outlet 223 can be provided with corresponding openable and closable door covers, so as to open or close the first outlet 222 and the second outlet 223 respectively, so as to output heating or cooling air respectively through the first outlet 222 and the second outlet 223. Figure 2 and Figure 3 If a partition is used to form the third equipment area 105 on the top of the aircraft 100, the first exit 222 and the second exit 223 can be respectively located on the partition facing the load-bearing area 101. This allows the corresponding door covers of the first exit 222 and the second exit 223 to be relatively flush with the partition when closed. Furthermore, the extension section 221 can also be located within the space separated by the partition. This means that the extension section 221 is located in the third equipment area 105 and communicates with the load-bearing area 101, thereby reducing the risk of interference or collision between passengers or objects and the extension section 221.

[0059] Among them, reference Figure 4 、 Figure 5 and Figure 6 The load-bearing area 101 is connected to the input port of the airflow driver 205 through the first circulation channel 230. The first circulation channel 230 is connected to the side of the load-bearing area 101 facing the belly of the aircraft 100. It can be understood that the first circulation channel 230 is connected to the bottom of the load-bearing area 101, so that when cold air or warm air enters from the top of the load-bearing area 101, it is convenient to extract the air in the load-bearing area 101 from the bottom, which is beneficial to improve the flow order of warm or cold air in the load-bearing area 101, so that the air in the load-bearing area 101 can circulate and improve the heat transfer efficiency, thereby better realizing internal circulation cooling or internal circulation heating.

[0060] In some embodiments, reference Figure 4 or Figure 6Aircraft 100 is provided with a first equipment air outlet 121, and the output port of air flow actuator 205 is connected to first equipment air outlet 121 via exhaust channel 240. Aircraft 100 also includes an air outlet valve assembly configured to open one of heat exchange channel 220 and exhaust channel 240 and close the other. For example, when load area 101 is connected to the input port of air flow actuator 205 via first circulation channel 230, heat exchange channel 220 can be opened and exhaust channel 240 can be closed, thereby achieving internal circulation cooling or heating. Alternatively, when the load-bearing area 101 is connected to the input port of the airflow driver 205 via the first circulation channel 230, the heat exchange channel 220 can be closed and the exhaust channel 240 can be opened, so that the air in the load-bearing area 101 can be discharged, for example, the smoke formed in the load-bearing area 101 can be discharged so that the air handling device 200 has a smoke removal function, thereby reducing the risk of smoke in the load-bearing area 101 endangering passengers or causing fire. It is understandable that, referring to Figure 4 or Figure 6 The aircraft 100 may also be provided with an equipment air inlet 111 for external air flow to enter the load-bearing area 101. The external air flow can be external fresh air, cold air from other air conditioners, or warm air. It can be understood that the equipment air inlet 111 is connected to the load-bearing area 101, so that when the flue gas, cold air or warm air after heat exchange are discharged from the load-bearing area 101, new air flow can be introduced into the load-bearing area 101 through the equipment air inlet 111.

[0061] Among them, reference Figure 5 or Figure 6 The portion of the heat exchange channel 220 facing the airflow driver 205 and the portion of the exhaust channel 240 facing the airflow driver 205 may share a common channel. In this case, the outlet valve assembly may include an outlet three-way valve disposed at the common junction of the heat exchange channel 220 and the airflow driver 205. Of course, if the portion of the heat exchange channel 220 facing the airflow driver 205 and the portion of the exhaust channel 240 facing the airflow driver 205 share a common channel, or if the heat exchange channel 220 and the exhaust channel 240 are independent of each other, the outlet valve assembly may include two valves disposed in the heat exchange channel 220 and the exhaust channel 240, respectively, to open and close the heat exchange channel 220 and the exhaust channel 240, respectively.

[0062] In some embodiments, reference Figure 4 In the direction of travel of the aircraft 100, the first equipment air outlet 121 can be located at the rear side of the carrying area 101 to reduce the risk of smoke backflowing into the carrying area 101 during travel. In addition, the first equipment air outlet 121 can be located at the rear side of the equipment air inlet 111 to reduce the risk of smoke backflowing into the carrying area 101 through the equipment air inlet 111 during travel.

[0063] In some embodiments, reference Figure 4 or Figure 6 The equipment air inlet 111 can be connected to the input port of the airflow driver 205 through the first air inlet channel 250, and the equipment air inlet 111 can also be connected to the carrying area 101 through the second air inlet channel 260; correspondingly, the aircraft 100 also includes an air inlet valve group, which is configured to: when the exhaust channel 240 is open, close the first air inlet channel 250, and open the second air inlet channel 260 and the first circulation channel 230 respectively; when the exhaust channel 240 is closed, close the second air inlet channel 260, and open at least one of the first air inlet channel 250 and the first circulation channel 230.

[0064] It can be understood that the air inlet valve group can include air inlet valve bodies respectively arranged in the first air inlet channel 250, the second air inlet channel 260 and the first circulation channel 230, so that each air inlet valve body respectively changes the on and off states of the first air inlet channel 250, the second air inlet channel 260 and the first circulation channel 230.

[0065] Among them, reference Figure 6 In some embodiments, the portion of the first air inlet channel 250 facing the device air inlet 111 and the portion of the second air inlet channel 260 facing the device air inlet 111 are connected through a first common channel 251, and the first common channel 251 is connected to the device air inlet 111; wherein, Figure 4 、 Figure 5 The overall length of the first common channel 251 is relatively long. Figure 6 The overall length of the first common channel 251 is relatively short. In addition, the second air inlet channel 260 can be arranged in parallel with the air flow channel of the air flow driver 205, so that when exhausting smoke from the carrying area 101, the smoke is discharged to the external environment through the first circulation channel 230, the air flow driver 205 and the exhaust channel 240, and fresh air is input into the carrying area 101 through the second air inlet channel 260, thereby reducing the risk of the input fresh air mixing with the smoke. Figure 5 The second air inlet channel 260 and the parallel portion of the air flow driver 205 can be arranged in the device box 290 of the air treatment device 200, thereby improving the external neatness of the air treatment device 200. Figure 6 The parallel connection part of the second air inlet channel 260 and the air flow driver 205 can be arranged outside the device box 290, so as to reduce the volume of the device box 290. Figure 5, part of the second air inlet channel 260 (the parallel portion of the second air inlet channel 260 and the air flow driver 205) is arranged in the device box 290 and is arranged side by side with the part of the heat exchange channel 220 located in the device box 290 (corresponding to the part of the air flow driver 205); or, referring to Figure 6 The second air inlet channel 260 is arranged outside the device box 290.

[0066] The device housing 290 included in the air treatment device 200 can be disposed in the first equipment area 102, thereby improving space utilization through the first equipment area 102. The first heat exchanger 201 and the air flow driver 205 are disposed in the device housing 290, thereby improving the integration of the air treatment device 200 and the convenience of overall movement.

[0067] Reference Figure 4 and Figure 5 illustrative embodiments, or reference Figure 6 In the illustrated embodiment, the device box 290 is provided with a first box inlet 291 and a second box inlet 292. A portion of the first circulation channel 230 is provided outside the device box 290 and has the supporting area 101 and the first box inlet 291 at both ends respectively.

Wherein, referring to Figure 4 The part of the first circulation channel 230 provided outside the device box 290 and the part of the first air inlet channel 250 provided outside the device box 290 can be respectively embedded in the aircraft 100, for example, embedded in the fuselage 108, so as to facilitate the parallel manufacturing of the first circulation channel 230 and the first air inlet channel 250, which is conducive to improving the overall manufacturing efficiency.

[0068] In addition, the device housing 290 is provided with a first housing outlet 293 and a second housing outlet 294; a portion of the exhaust channel 240 is provided inside the device housing 290 and its two ends are respectively connected to the output port of the airflow driver 205 and the first housing outlet 293, and another portion of the exhaust channel 240 is provided outside the device housing 290 and its two ends are respectively connected to the first housing outlet 293 and the first device air outlet 121; a portion of the heat exchange channel 220 is provided inside the device housing 290 and its two ends are respectively connected to the output port of the airflow driver 205 and the second housing outlet 294, and another portion of the heat exchange channel 220 is provided outside the device housing 290 and its two ends are respectively connected to the second housing outlet 294 and the carrying area 101, thereby improving the convenience of disassembly and assembly of the exhaust channel 240 and the heat exchange channel 220. Figure 4 The portion of the exhaust channel 240 outside the device box 290 and the portion of the heat exchange channel 220 outside the device box 290 can be respectively embedded in the aircraft 100, for example, embedded in the fuselage 108, so as to facilitate the parallel manufacturing of the exhaust channel 240 and the heat exchange channel 220, which is beneficial to improving the overall manufacturing efficiency.

[0069] Reference Figure 4 or Figure 6 The first common channel 251 corresponding to the above-mentioned first air inlet channel 250 can be set outside the device box 290, so as to facilitate the parallel manufacturing of the first common channel 251 (the common part of the first air inlet channel 250 and the second air inlet channel 260), which is conducive to further improving the overall manufacturing efficiency.

[0070] The first common channel 251 may be understood as a portion commonly used by the first air inlet channel 250 and the second air inlet channel 260 , or may be understood as a portion commonly included by the first air inlet channel 250 and the second air inlet channel 260 .

[0071] In addition, refer to Figure 6 In some embodiments, the portion of the first air inlet channel 250 facing the airflow driver 205 and the portion of the first circulation channel 230 facing the airflow driver 205 are connected by a second common channel 252, and the second common channel 252 is connected to the input port of the airflow driver 205. The second common channel 252 can be understood as the portion shared by the first air inlet channel 250 and the first circulation channel 230, or can also be understood as the portion shared by the first air inlet channel 250 and the first circulation channel 230.

[0072] In some embodiments, the air inlet valve group includes a movably arranged door assembly, which is connected to the first common channel 251, and the door assembly is used to change the on-off state of the first air inlet channel 250 and the on-off state of the second air inlet channel 260; wherein, the door assembly may include movable doors respectively arranged corresponding to the first air inlet channel 250 and the second air inlet channel 260, thereby respectively changing the on-off state of the first air inlet channel 250 and the second air inlet channel 260.

[0073] In addition, refer to Figure 5 or Figure 6 The air inlet valve group may further include a three-way valve 253, a first input port and a second input port of the three-way valve 253 respectively connected to a portion of the first air inlet channel 250 away from the air flow driver 205 and a portion of the first circulation channel 230 away from the air flow driver 205, and an output port of the three-way valve 253 connected to the second common channel 252. The three-way valve 253 is configured to connect one of the portion of the first air inlet channel 250 away from the air flow driver 205 and the portion of the first circulation channel 230 away from the air flow driver 205 to the second common channel 252.

[0074] In some embodiments, reference Figure 3 or Figure 4 , along the traveling direction of the aircraft 100, when the airflow driver 205 is arranged in the first equipment area 102 on the rear side of the carrying area 101, the equipment air inlet 111 connected to the airflow driver 205 can be arranged on the rear side of the carrying area 101 to shorten the channel length from the equipment air inlet 111 to the airflow driver 205, thereby shortening the overall air intake path.

[0075] In some embodiments, reference Figure 3 or Figure 4The aircraft 100 is provided with a second equipment air outlet 122, which is connected to the first air inlet duct 250 via a second circulation channel 270. The second circulation channel 270 is used to allow external air to flow from the equipment air inlet 111 to the second equipment air outlet 122, thereby transmitting airflow entering from the equipment air inlet 111 and the first air inlet duct 250 to the second equipment air outlet 122. For example, during the movement of the aircraft 100, the relative speed between the external environment and the aircraft 100 causes the external airflow to flow sequentially through the equipment air inlet 111, the first air inlet duct 250, and the second equipment air outlet 122. The second heat exchanger 203 is disposed in the second circulation channel 270 to exchange heat with the airflow in the second circulation channel 270, thereby improving the heat exchange efficiency through the second circulation channel 270. For example, when the first heat exchanger 201 cools the load area 101, the second heat exchanger 203 dissipates heat to the airflow in the second circulation channel 270. When the first heat exchanger 201 has a heating function and heats the carrying area 101 , the second heat exchanger 203 can absorb heat from the second circulation channel 270 .

[0076] In addition, the aircraft 100 may further include a heat exchange valve configured to change the on / off state of the second circulation channel 270, thereby starting or stopping heat exchange between the second heat exchanger 203 and the airflow in the second circulation channel 270. For example, the heat exchange valve may be disposed in the second circulation channel 270 to open or close the second circulation channel 270.

[0077] In some embodiments, the second device air outlet 122 can be configured to be connected to the first device air outlet 121, thereby reducing the number of openings on the aircraft 100 and reducing the wind resistance of the aircraft 100 during movement; further, the second device air outlet 122 and the first device air outlet 121 can be configured to at least partially overlap, including partial overlap of the second device air outlet 122 and the first device air outlet 121, and complete overlap of the second device air outlet 122 and the first device air outlet 121 (which can be understood as the second device air outlet 122 and the first device air outlet 121 being configured as the same air outlet), thereby further reducing the wind resistance of the aircraft 100 during movement.

[0078] In some embodiments, reference Figure 3 or Figure 4 The aircraft 100 is provided with a third equipment air outlet 123, which is connected to the first circulation channel 230 through the third circulation channel 280, so that the air from the carrying area 101 is discharged outward through the third circulation channel 280, thereby facilitating the replacement of the air in the carrying area 101 by the air intake through the equipment air inlet 111. Figure 6The aircraft 100 may further include a discharge valve 281, which is used to change the on-off state of the third circulation channel 280, thereby facilitating the opening or closing of exhaust through the third circulation channel 280. The discharge valve 281 may be provided in the third circulation channel 280. In addition, the discharge valve 281 may be provided as a pressure relief valve, thereby improving the convenience of pressure relief in the carrying area 101. It can be understood that the discharge valve 281 is connected to the carrying area 101 through a pressure relief channel (such as the above-mentioned third circulation channel 280), and the discharge valve 281 is configured to discharge the pressure of the carrying area 101 to the external environment of the aircraft 100.

[0079] With reference to the above embodiments, the air handling device 200 and the aircraft 100 may operate in the following modes, and each component may be configured with a corresponding structure or state.

[0080] In the case where smoke exhaust is required for the carrying area 101, refer to Figure 4 , you can turn off Figure 4 The third device outlet 123 is provided to prevent the air from the external environment from entering the carrying area 101 in large quantities through the third device outlet 123 and the third circulation channel 280, which is conducive to improving the efficiency of exhausting smoke from the carrying area 101; in addition, referring to Figure 7 When the parallel portion of the second air inlet channel 260 and the air flow driver 205 is located outside the device housing 290, the external air of the aircraft 100 can enter the carrying area 101 through the equipment air inlet 111, the second air inlet channel 260, and the extension section 221; the air in the carrying area 101 is sucked into the air flow driver 205 through the first circulation channel 230, the first housing inlet 291, the three-way valve 253, and the filter structure 207, and is discharged to the external environment through the first housing outlet 293, the exhaust channel 240, and the first equipment air outlet 121, thereby achieving smoke exhaust in the carrying area 101. Figure 4 and Figure 5 When the parallel portion of the second air inlet channel 260 and the airflow driver 205 is disposed within the device housing 290, air outside the aircraft 100 can enter the load compartment 101 via the equipment air inlet 111, the second housing inlet 292, the second air inlet channel 260, the second housing outlet 294, and the heat exchange channel 220. Air within the load compartment 101 is drawn into the airflow driver 205 through the first circulation channel 230, the first housing inlet 291, the three-way valve 253, and the filter structure 207, and then discharged to the outside environment through the first housing outlet 293, the exhaust channel 240, and the first equipment air outlet 121, thereby exhausting smoke from the load compartment 101. It is understood that when smoke exhaust from the load compartment 101 is required, the first heat exchanger 201, the compressor 202, the second heat exchanger 203, the throttling device 204, and the heater 206 are inoperative.

[0081] Reference Figure 8 , when external circulation cooling is required, the first box inlet 291 and the first box outlet 293 of the device box 290 can be closed, and the second box inlet 292 and the second box outlet 294 can be opened; the air from the external environment flows through the equipment air inlet 111 and the second box inlet 292, and the first heat exchanger 201, the compressor 202, the second heat exchanger 203, and the throttling device 204 work to cool the first heat exchanger 201; in addition, the heater 206 does not work; in the device box 290, the air at the second box inlet 292 continues to flow through the three-way valve 253, the filter structure 207, the air flow driver 205, the first heat exchanger 201, and the second box outlet 294; the cold air at the second box outlet 294 then flows through the extension section 221 of the heat exchange channel 220 and the load-bearing area 101, and can pass through the discharge valve 281 (which can be further set as a pressure relief valve), Figure 4 The air is discharged to the outside environment through the second device air outlet 122. The second heat exchanger 203 can dissipate heat through the external airflow corresponding to the movement of the aircraft 100. In the case of external circulation cooling, fresh air outside the aircraft 100 is cooled by the first heat exchanger 201 and then flows to the load area 101, thereby cooling the load area 101.

[0082] Reference Figure 9 When internal circulation cooling is required, the second tank inlet 292 and first tank outlet 293 of the device housing 290 can be closed, and the first tank inlet 291 and second tank outlet 294 can be opened. The heater 206 is deactivated, and the first heat exchanger 201, compressor 202, second heat exchanger 203, and throttling device 204 are activated to cool the first heat exchanger 201. Within the device housing 290, air from the first tank inlet 291 flows through the three-way valve 253, the filter structure 207, the air flow driver 205, the first heat exchanger 201, and the second tank outlet 294. The load area 101 is not connected to the external environment. The cold air from the second tank outlet 294 then flows through the extension section 221 of the heat exchange channel 220, the load area 101, the first circulation channel 230, and the first tank inlet 291, achieving air circulation within the aircraft 100 and cooling the load area 101. The second heat exchanger 203 can dissipate heat through the external airflow corresponding to the movement of the aircraft 100 .

[0083] Reference Figure 10, when external circulation heating is required, the first box inlet 291 and the first box outlet 293 of the device box 290 can be closed, and the second box inlet 292 and the second box outlet 294 can be opened; the air from the external environment flows through the equipment air inlet 111 and the second box inlet 292, and the first heat exchanger 201, the compressor 202, the second heat exchanger 203, and the throttling device 204 do not work; in addition, the heater 206 works to heat; in the device box 290, the air at the second box inlet 292 continues to flow through the three-way valve 253, the filter structure 207, the air flow driver 205, the heater 206, and the second box outlet 294; the warm air at the second box outlet 294 then flows through the extension section 221 of the heat exchange channel 220 and the bearing area 101, and can pass through the discharge valve 281 (which can be further set as a pressure relief valve), Figure 4 The air is discharged to the external environment through the second equipment air outlet 122. In the case of external circulation heating, the fresh air outside the aircraft 100 is heated by the heater 206 and then flows to the carrying area 101, thereby heating the carrying area 101.

[0084] Reference Figure 11 When internal circulation heating is required, the second tank inlet 292 and first tank outlet 293 of the device housing 290 can be closed, and the first tank inlet 291 and second tank outlet 294 can be opened. The heater 206 operates to generate heat, while the first heat exchanger 201, compressor 202, second heat exchanger 203, and throttling device 204 do not operate. Within the device housing 290, air from the first tank inlet 291 flows through the three-way valve 253, the filter structure 207, the air flow driver 205, the heater 206, and the second tank outlet 294. The load area 101 is not connected to the external environment. The heated air from the second tank outlet 294 then flows through the extension section 221 of the heat exchange channel 220, the load area 101, the first circulation channel 230, and the first tank inlet 291, achieving air circulation within the aircraft 100 and heating the load area 101.

[0085] Reference Figure 12 , the above-mentioned aircraft 100 and air handling device 200 can also be connected to other air conditioners to achieve cooling or heating. In the case where the aircraft 100 is set as an aircraft of the type of eVTOL, the above-mentioned aircraft 100 and air handling device 200 can be connected to ground air conditioners to achieve cooling or heating. Among them, the first box inlet 291 and the first box outlet 293 of the device box 290 can be closed, and the second box inlet 292 and the second box outlet 294 can be opened, the heater 206 does not work, the first heat exchanger 201, the compressor 202, the second heat exchanger 203, and the throttling device 204 do not work. The cooling or heating of other air conditioners can be achieved through Figure 4The air flow is connected to the equipment air inlet 111 of the aircraft 100 in the device box 290, and then flows through the second box inlet 292; in the device box 290, the air flow at the second box inlet 292 continues to flow through the three-way valve 253, the filter structure 207, the air flow driver 205, and the second box outlet 294; the air flow at the second box outlet 294 then flows through the extension section 221 of the heat exchange channel 220, the load-bearing area 101, and can pass through the discharge valve 281 (which can be further configured as a pressure relief valve), Figure 4 The air is discharged to the external environment through the second equipment air outlet 122. The aircraft 100 can be connected to the cooling air or heating air of other external air conditioners through the equipment air inlet 111 to achieve cooling or heating of the carrying area 101.
