[0049] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0050] Please refer to Figures 1 to 10 , Figure 1 This is a schematic diagram of the structure of a low-energy consumption cycle temperature recovery power supply pod in an embodiment of the present application; Figure 2 for Figure 1 The front view of the low energy consumption cycle heat recovery power supply pod shown; Figure 3 for Figure 1 The schematic diagram of the structure of the cabin in the low-energy consumption cycle heat recovery power supply pod shown;

[0052] The low-energy consumption circulating temperature recovery power supply pod provided in the embodiment of the present application includes an air guide cover 1, a pod body 2 and a tail cover 3, wherein the air guide cover 1, the pod body 2 and the tail cover 3 are connected in sequence.

[0053] It should be noted that the pod body 2 of the power supply pod is composed of a pod frame structure and a skin, and the wind guide cover 1 and the tail cover 3 are respectively installed at the head and tail of the pod body 2. The pod body 2 is divided into three chambers according to the radial skeleton, namely the head chamber 21, the middle chamber 22 and the tail chamber 23.

[0054] Furthermore, the air guide cover 1 is provided with a main air inlet 11 and an auxiliary air inlet 12, and the tail cover 3 is provided with a main air outlet 31 and an auxiliary air outlet 32. The main air outlet 31 is arranged opposite to the main air inlet 11, and the auxiliary air outlet 32 ​​is arranged opposite to the auxiliary air inlet 12. At the same time, the power supply pod also includes an air duct 4, which is connected to the main air inlet 11 and extends to the tail of the pod body 2.

[0055] In this way, the airflow entering from the main air inlet 11 flows along the air duct 4 to the tail hood 3, and the airflow entering from the auxiliary air inlet 12 flows through the cabin 2 to the tail hood 3, and then flows out from the main air outlet 31 and the auxiliary air outlet 32. That is to say, the airflow entering from both the main air inlet 11 and the auxiliary air inlet 12 flows into the cabin 2, the airflow flowing into the air duct 4 through the main air inlet 11 exchanges heat with the air in the cabin 2, and the airflow flowing into the cabin 2 through the auxiliary air inlet 12 directly cools the air in the cabin 2, and finally flows out from the tail hood 3, thereby realizing the heat dissipation of the cabin 2.

[0056] Compared with the traditional power supply pod, the low-energy consumption circulating temperature recovery power supply pod provided in the embodiment of the present application introduces cooling airflow into the cabin body 2 through the main air inlet 11 and the auxiliary air inlet 12 to dissipate heat for the working parts in the cabin body 2. This can improve the heat dissipation performance of the power supply pod and increase the cooling effect of the working parts in the power supply pod, thereby improving the stability and reliability of the system operation.

[0057] In some embodiments, the main air inlet 11 is disposed in the middle of the air guide cover 1, the main air outlet 31 is disposed in the middle of the tail cover 3, and both the main air inlet 11 and the main air outlet 31 are circular structures.

[0058] It should be noted that the entire air guide cover 1 and the tail cover 3 preferably adopt a hemispherical structure, with the main air inlet 11 arranged in the middle of the air guide cover 1, and the main air outlet 31 arranged in the middle of the tail cover 3. The main air inlet 11 and the main air outlet 31 are coaxially arranged, which can achieve the most efficient air flow, thereby improving the heat dissipation efficiency.

[0059] In some embodiments, the auxiliary air inlet 12 is arranged at the top of the air guide cover 1, and the auxiliary air outlet 32 ​​is arranged at the top of the tail cover 3, or the auxiliary air inlet 12 is arranged at the bottom of the air guide cover 1, and the auxiliary air outlet 32 ​​is arranged at the bottom of the tail cover 3.

[0060] In addition, the auxiliary air inlet 12 and the auxiliary air outlet 32 ​​have the same structure. Specifically, the auxiliary air inlet 12 is arranged at the top of the air guide cover 1, and the auxiliary air outlet 32 ​​is arranged at the top of the tail cover 3, and the structures of the auxiliary air inlet 12 and the auxiliary air outlet 32 ​​include but are not limited to rectangular openings, circular openings, and a combination of rectangular and circular structures.

[0061] In some embodiments, a damper plate 41 is provided at one end of the air duct 4 close to the main air inlet 11, and a plurality of air inlet holes are provided on the damper plate 41, and the damper plate 41 is used to adjust the air intake of the air duct 4. A wind shield plate may be provided inside the damper plate 41, and the purpose of adjusting the air intake can be achieved by shielding a preset number of air inlet holes with the wind shield plate.

[0062] In this way, the airflow entering from the main air inlet 11 enters the air guide duct 4 through the air damper plate 41 and blows toward the rear of the cabin 2 , thereby cooling the working components at the rear of the cabin 2 .

[0063] In some embodiments, the power supply pod also includes a first vent ear 51 and a second vent ear 52. The first vent ear 51 is disposed at the head cabin 21, and the first vent ear 51 is used for allowing external airflow to enter the head cabin 21 from the side of the head cabin 21; the second vent ear 52 is disposed at the tail cabin 23, and the second vent ear 52 is used for allowing external airflow to enter the tail cabin 23 from the side of the tail cabin 23.

[0064] That is to say, on the basis of introducing the cooling airflow through the main air inlet 11 and the auxiliary air inlet 12, the power supply pod is also provided with a first air intake ear 51 on the head cabin 21 and a second air intake ear 52 on the tail cabin 23, so as to facilitate the external cooling airflow to enter the cabin body 2 from the first air intake ear 51 and the second air intake ear 52, so as to provide further heat dissipation for the working parts in the cabin body 2.

[0065] The first windshield ears 51 and the second windshield ears 52 are mainly used to increase the amount of lateral airflow entering during flight, thereby increasing the cooling effect of the engine.

[0066] In some embodiments, a first wind shield 61 is provided in the head cabin 21, and the first wind shield 61 has a first wind shield groove, and the airflow entering from the first wind ear 51 gathers at the first wind shield groove and flows to the engine in the head cabin 21; a second wind shield 62 is provided in the tail cabin 23, and the second wind shield 62 has a second wind shield groove, and the airflow entering from the second wind ear 52 gathers at the second wind shield groove and flows to the engine in the tail cabin 23.

[0067] It should be noted that in the embodiment of the present application, the fuel tank and the lithium battery are placed in the middle compartment 22 of the power supply pod, and the two engine groups are respectively arranged in the head compartment 21 and the tail compartment 23. The airflow entering the cabin 2 from the first windshield ear 51 is gathered at the first windshield slot and flows to the engine in the head compartment 21 to dissipate heat for the engine in the head compartment 21; the airflow entering from the second windshield ear 52 is gathered at the second windshield slot and flows to the engine in the tail compartment 23 to dissipate heat for the engine in the tail compartment 23.

[0068] Specifically, the structures of the first wind deflector 61 and the second wind deflector 62 can be the same, and the structures of the first wind deflector 61 and the second wind deflector 62 can be set as a combined plate structure, which can include two baffles set at a preset angle, the ends of the two baffles can be connected or not, and two side plates are respectively provided on both sides of the combined plate structure, and the two side plates are respectively connected to the two baffles. The so-called baffle refers to a plate for airflow to flow in a specified direction. In this way, the two baffles and the two side plates together form a windshield groove for airflow to gather in the windshield groove.

[0069] In this way, the airflow entering the head cabin 21 and the tail cabin 23 from the side will be blocked by the first wind deflector 61 and the second wind deflector 62 respectively, so that the gas forms a vortex nearby, thereby increasing the heat dissipation effect of the engine in the corresponding cabin 2.

[0070] In some embodiments, a first wind guide plate 71 is further provided in the head cabin 21, and the first wind guide plate 71 is arranged toward the first wind shield plate 61, and the first wind guide plate 71 has a plurality of first wind guide grooves, and the airflow flows toward the middle cabin 22 after passing through the plurality of first wind guide grooves; a second wind guide plate 72 is further provided in the tail cabin 23, and the second wind guide plate 72 is arranged toward the second wind shield plate 62, and the second wind guide plate 72 has a plurality of second wind guide grooves, and the airflow flows out of the tail cabin 23 after passing through the plurality of second wind guide grooves.

[0071] That is to say, the first air guide plate 71 and the second air guide plate 72 play a role of guiding air, and the first air guide plate 71 and the second air guide plate 72 have the same structure.

[0072] In some embodiments, the first air guide plate 71 and the second air guide plate 72 both include an arc-shaped plate 73, a first folding plate 74 and two second folding plates 75, wherein the first folding plate 74 is arranged in the middle of the arc-shaped plate 73; the two second folding plates 75 are respectively arranged at both ends of the arc-shaped plate 73; wherein the first folding plate 74 and the two second folding plates 75 are arranged on the same side of the arc-shaped plate 73, and any second folding plate 75 and the first folding plate 74 form a first air guide groove or a second air guide groove.

[0073] Preferably, the first folding plate 74 and the second folding plate 75 are both L-shaped plates, that is, any air guide groove is formed by the arc plate 73 and two L-shaped plates arranged on the arc plate 73, and the air flow flows along the air guide groove to the designated position.

[0074] In some embodiments, the power supply pod also includes a first exhaust duct 81 and a second exhaust duct 82, wherein the first exhaust duct 81 is connected to the air duct 4, the first exhaust duct 81 extends from the side wall of the head cabin 21, and the first exhaust duct 81 is used to achieve exhaust; the second exhaust duct 82 is connected to the air duct 4, the second exhaust duct 82 extends from the side wall of the tail cabin 23, and the second exhaust duct 82 is used to achieve exhaust.

[0075] In summary, the airflow entering from the main air inlet 11 flows in through the air duct 4, a small part of the airflow after heat exchange is discharged through the first exhaust pipe 81 and the second exhaust pipe 82, and most of the airflow after heat exchange flows out through the main air outlet 31 and the auxiliary air outlet 32; the airflow entering from the auxiliary air inlet 12 enters the cabin 2, undergoes heat exchange, and then flows out from the main air outlet 31 and the auxiliary air outlet 32; the airflow entering from the first windshield 51 and the second windshield 52 enters the cabin 2, and is blocked by the first windshield 61 and the second windshield 62 arranged on the side of the engine, respectively, so that the airflow is gathered and the engine is cooled, and then flows out from the main air outlet 31 and the auxiliary air outlet 32. The above process can achieve heat dissipation for the working parts in the cabin 2, especially the engine group.

[0076] The arrangement of the working components in the cabin 2 will be described in detail below.

[0077] Specifically, the power supply pod is mainly composed of an air deflector 1, a pod body 2, a tail cover 3, two DB403 engine assemblies, two generator assemblies, two motor controllers, a lithium battery pack, two suspension systems, a fuel tank, and two engine wiring harness assemblies.

[0078] The fuel tank and lithium battery are placed in the middle cabin 22 of the power supply pod, and the fuel tank is arranged below the lithium battery pack. The lithium battery pack is suspended and fixed on the main beam on the pod frame structure, and the fuel tank is fixed on the main beam under the pod frame structure; in the middle cabin 22, two generator controllers are arranged on both sides of the fuel tank and the lithium battery pack, and are fixed to the two radial frames of the middle cabin 22 in an upright state by bolts. Two sets of diesel generator sets are symmetrically arranged on both sides of the controller, namely in the head cabin 21 and the tail cabin 23. The generator and the diesel engine crankshaft are connected by a clutch plate to reduce the damage to the engine caused by torsional vibration during the connection between the generator and the engine. Two sets of ECUs are arranged above the generators, and are suspended and fixed to the front and rear end brackets of the pod frame structure by bolts. Both generator sets are fixed to the pod frame structure by three points.

[0079] The power supply control of the entire power supply pod is precise. During operation, the fuel tank is set in the middle position, which has little impact on the center of gravity. The generator and the controller are far apart, so the vibration of the generator does not affect the normal operation of the controller, and reduces the electromagnetic impact of the generator on the battery pack and the controller. In addition, the ECU and the generator maintain a stable temperature under the cooling effect of the air outlet, and will no longer heat up rapidly and cause the temperature of the entire power supply pod to overheat. Reduce the instability of drone signals caused by excessively high or low temperatures, increase the controllability of temperature, and reduce the stability of the continuous control of drone transceiver signals and their own signals caused by weather factors.

[0080] The generator assembly is an integrated motor, which is based on the reversible operation principle of the motor, and uses the motor as a starter and a generator. During the engine starting phase, the motor operates as an electric motor, converting electrical energy into mechanical energy and driving the engine to idle speed. After the start is successful, the engine can in turn drive the motor to operate, converting mechanical energy into electrical energy, and the motor operates as a generator.

[0081] The generator assembly structure is a permanent magnet synchronous motor. The motor generates a synchronous rotating magnetic field by permanent magnet excitation. The permanent magnet acts as a rotor to generate a rotating magnetic field. The three-phase stator winding induces a three-phase symmetrical current through armature reaction under the action of the rotating magnetic field. At this time, the rotor converts mechanical energy into electrical energy, and the permanent magnet synchronous motor is used as a generator; in addition, when a three-phase symmetrical current is passed through the stator side, since the three-phase stator is 120 degrees apart in spatial position, the three-phase stator current generates a rotating magnetic field in space, and the rotor moves in the rotating magnetic field under the action of electromagnetic force. At this time, the electrical energy is converted into kinetic energy, and the permanent magnet synchronous motor is used as a motor.

[0082] The integrated starter and generator reduces the size and weight of the APU power system and improves its efficiency. The permanent magnet motor uses permanent magnets with high remanence, high coercive force and high magnetic energy product for excitation, and has the advantages of high power density, large starting torque and strong overload capacity.

[0083] In this structure, the energy demand unit and the engine can be completely decoupled and run, so that the engine operating conditions are optimized to a great extent and can work in the economic zone. Under the premise of ensuring the power generation, system power performance, fuel economy and emissions, it is necessary to reasonably adjust the energy flow between the engine and the generator. When designing the APU starting power generation system, the engine operating high efficiency zone should be determined according to the universal characteristic curve of the engine, and at the same time, avoid excessive fluctuations in the engine speed, thereby reducing fuel consumption and improving fuel economy.

[0084] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0085] The above is a detailed introduction to the low-energy consumption circulating temperature recovery power supply pod provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the scheme of the present application and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
