[0039] According to a second main aspect of the present invention, a heat dissipation method is provided, which utilizes a two-layer independent cooling medium circulation system. The two-layer independent cooling medium circulation system is designed with a two-part structure of inner cooling flow channels and outer cooling flow channels to evenly distribute the cooling medium to the high-temperature areas of the motor and control system in the integrated system of the control system and the motor;

[0040] The inner cooling medium directly contacts and absorbs the heat from the high-temperature area, while the outer cooling medium cools the unit modules, forming a double-layer heat dissipation mechanism.

[0043] Compared with the prior art, the present invention realizes the integration of the unit modules and the motor by distributing the unit modules that control and / or drive different devices in a pluggable manner on the inner shell arranged around the motor. The double-layer structure cooling design of the inner cooling channel arranged on the inner shell and the outer cooling channel arranged on the outer shell surrounding the inner shell is used to directly cool the high-temperature areas of the motor and the control system, thereby achieving effective heat dissipation of the motor and the unit modules. At the same time, the pluggable unit modules improve the flexibility and maintenance convenience of the system. This design not only optimizes space utilization and promotes the miniaturization of the system, but also improves the overall heat dissipation efficiency through centralized heat dissipation, ensuring the integration of the control system and the motor, and the effective operation of the performance after miniaturization.

[0044] The dual-layer liquid cooling mechanism of this invention achieves uniform cooling of the high-temperature areas of the motor and control system through two independent inner and outer cooling medium circulation systems. The inner cooling medium directly absorbs heat from these high-temperature areas, while the outer cooling medium cools the unit modules, forming a highly efficient dual-layer heat dissipation structure. Furthermore, through intelligent control of the four-way valve, the cooling medium flow direction can be dynamically adjusted based on temperature feedback, thereby optimizing heat dissipation efficiency and reducing energy consumption.

[0045] The solution of the present invention has the following significant advantages: first, the heat dissipation efficiency is higher, and heat can be quickly removed from the unit module and the motor; second, the heat dissipation performance is more stable and is not easily affected by environmental factors; third, the noise is lower, because the cooling medium is used for circulating heat, which reduces the use of rotating parts such as fans; fourth, the service life is longer, because the temperature of the unit module and the motor is effectively controlled, which reduces the risk of damage to electronic components and motors due to high temperature.

[0046] The above-mentioned integrated system equipment has the following advantages: First, it has high flexibility. Since the unit modules of the control system adopt a pluggable design, the maintenance and upgrade process is simplified; second, it has high reliability and strong fault tolerance. When a unit module fails, the system can quickly switch to the backup unit module; third, it has high durability and a long service life of the system. This is because materials with good thermal conductivity and high strength are used to manufacture the motor housing and heat dissipation teeth, and the integrated system is designed in a layered manner, and the layout of electronic components is planned.

[0047] The present invention arranges the hybrid power system in an integrated space, so that after the entire integrated system is independently installed, it can be applied as a whole to different application scenarios, such as aircraft (for example, drones, manned aircraft, airships, helicopters, etc.), ships, special vehicles (such as ambulances, fire trucks, police cars, engineering rescue vehicles, military supervision vehicles, etc.) and other equipment, which is conducive to rapid installation and overall maintenance. Moreover, in conjunction with the air intake and exhaust of the integrated space, the integrated heat dissipation of the hybrid power system can be optimized, and there is no need to configure an air cooling device for each device. It is more conducive to miniaturization and integration, and is also more conducive to intelligent control of thermal management.

[0048] In addition, the present invention sets the hybrid power system in an integrated space through a hybrid power integration system, provides air cooling through the air intake and exhaust of the integrated space, and further enhances the heat dissipation and cooling of each device in the hybrid power system, so that, for example, the control system of the motor can obtain a good cooling effect.

[0066] Example:

[0067] like Figure 1-9 As shown, the integrated system 1 of the control system and the motor of the present invention comprises: a motor, an inner shell 17 arranged around the motor, a control system, an outer shell 16 arranged around the inner shell 17 and having a gap between the inner shell (17), and end covers 2 for sealing at both ends, wherein:

[0068] An inner cooling channel 8 for allowing a cooling medium to pass through is provided on the inner shell 17, and an outer cooling channel 7 for allowing a cooling medium to pass through is provided on the outer shell 16;

[0069] The control system includes a main control board for overall control, which is arranged on any one of the end covers 2 and is installed at the installation position 22 on the end cover 2; and a variety of unit modules 12 for controlling and / or driving different devices. The unit modules 12 are electrically connected to the main control board and can communicate with each other.

[0070] By the electrical connection between the main control board and the unit modules, electrical conduction is carried out, and by the communication between the main control board and the unit modules, all unit modules 12 can be controlled overall. According to the operating conditions, the fixed unit modules 12 can be controlled to start, regulate and stop the corresponding equipment.

[0071] The various unit modules 12 are pluggable and distributed around the outer wall of the inner shell 17. Figure 7As can be seen from the figure, it is located between the inner shell 17 and the outer shell 16 and located on the inner side of the outer cooling channel 7, so that the unit module 12 is cooled by the cooling medium flowing through the outer cooling channel 7.

[0072] Two end caps 2 are provided at both ends of the entire integrated system 1 for sealing. Figure 1 This is a schematic diagram of one of the end covers 2. The end cover 2 is divided into an inner and outer layer and is arranged at both ends of the integrated system 1 of the control system and the motor. When disassembly is required, the entire end cover 2 is disassembled to replace the unit module 12; Figure 2 Schematic diagram of the outer end cover 3; Figure 3 It is a schematic diagram of the inner end cover 4; an internal line channel 5 and a line outlet channel 6 are provided on it, through which the various lines of the entire integrated system 1 are arranged, which is convenient for direct or indirect connection with an external power supply or communication with the outside. For example, the entire line can be connected through an aviation plug, and then connected to the external power supply and communication.

[0073] according to Figure 4-9 As shown, the present invention is an integrated system 1 that integrates a control system and a motor. An inner housing 17 surrounds the motor, and an outer housing 16 surrounds the inner housing 17. There is a gap, or space, between the outer housing 16 and the outer housing 17. Heat dissipation teeth 18 are provided on the outer housing 16; external cooling channels 7 are provided on the outer housing 16, and internal cooling channels 8 are provided on the inner housing 17. Different unit modules 12 are pluggable and distributed around the outer wall of the inner housing 17, that is, arranged between the inner housing 17 and the outer housing 16, and mounted around the outer wall of the inner housing 17.

[0074] The outer shell 16, the inner shell 17, the outer cooling channel 7 and the inner cooling channel 8 are all made of heat-conducting materials.

[0075] In one example, the multiple unit modules 12 are used at least to control and / or drive relevant components in a hybrid system, where the hybrid system outputs electrical energy by driving a motor through a gas turbine engine. The multiple unit modules 12 include, but are not limited to, any combination of an induction motor drive controller, a fuel oil cooling medium pump motor drive controller, an electrical energy output motor drive controller, an engine controller, an AC-DC inverter controller, and a power management controller, wherein:

[0076] Induction motor drive controller: This controller is responsible for starting, operating, and monitoring the status of the gas turbine engine's induction motor. It controls the induction motor drive system and adjusts the generator's output voltage, frequency, and other parameters to ensure stable and efficient power generation.

[0077] Gas-fired motor bearing coolant pump motor drive controller: This controller is specifically responsible for driving the pump motor that delivers the coolant (usually lubricating oil) from the oil heat exchanger 41 to the bearings. Its primary function is to ensure proper cooling and lubrication of the bearings, preventing overheating and wear. This controller also monitors the operating status of the pump motor to ensure the effective operation of the cooling system.

[0078] Electric energy output motor drive controller: In this example, it is the controller of the motor in the integrated system 1 of the control system and the motor. This controller is used to drive and control the operation of the motor. It may involve operations such as starting, accelerating, decelerating, and stopping the motor, and may include precise control of parameters such as motor speed, torque, and position. The corresponding motor is a motor that is driven by a gas turbine engine to output electric energy. Preferably, the motor is a high-speed motor.

[0079] Engine Controller Unit (ECU): The ECU is the core component of this system. It reads data from various sensors (such as MAP sensor, throttle position sensor, air temperature sensor, etc.) and adjusts the engine's operating parameters (such as fuel injection amount, ignition timing, etc.) in real time to optimize engine performance, fuel economy and emission levels.

[0080] AC-DC inverter controller: This controller converts alternating current (AC) into direct current (DC). It is widely used in applications where AC needs to be converted to DC suitable for electronic equipment. The controller also includes functions such as voltage regulation and overload protection to ensure a safe and stable conversion process.

[0081] Power Management Controller: The power management controller is responsible for managing and allocating power resources across the entire system. This includes monitoring power supply status (such as voltage, current, and power), controlling power on and off, and optimizing power distribution to improve energy efficiency. Furthermore, the power management controller provides fault detection and alarm functions to ensure system power stability and reliability. Within the system, the power management controller also communicates with other systems (such as the engine controller and battery management system) to enable more sophisticated power management and optimization.

[0082] In the hybrid power system of this embodiment, the gas turbine engine and the motor driving the engine to output electrical energy are connected via a shaft. In one example, specifically:

[0083] The gas turbine engine comprises:

[0084] The compressor assembly includes: an initiator motor, an air inlet integrated cover, and a compressor, wherein the compressor is connected to the initiator motor and the air inlet integrated cover respectively;

[0085] A combustion chamber assembly, the combustion chamber assembly comprising: a diffuser, guide vanes and a combustion chamber connected in sequence, wherein the compressor is connected to the diffuser;

[0086] A gas turbine assembly includes: a gas turbine rotatably connected to the compressor, wherein air entering from the compressor assembly enters the combustion chamber and then drives the gas turbine to rotate, and the rotational force of the gas turbine is transmitted to the compressor through a shaft system;

[0087] an exhaust damper assembly, the exhaust damper assembly being in communication with the combustion chamber and the hot gas outlet, respectively, and being adjacent to the heat insulation layer, for discharging hot gas remaining from combustion;

[0088] The power turbine and the gas turbine generate high-temperature and high-pressure gas to drive the power turbine to rotate and output mechanical work to the output motor. The power turbine and the gas turbine can be connected by a direct shaft or through a coupling, gearbox, etc.

[0089] The output motor is a high-speed motor with a speed greater than or equal to 20,000 r / min.

[0090] In addition, the inner cooling channel 8 can be a coil or a through groove opened around the inner shell 17, can be set around the outside or inside of the inner shell 17, or a gap can be opened on the inner shell 17 and the inner cooling channel 8 can be set in the gap. Similarly, the outer cooling channel 7 is also the same.

[0091] The "through groove" is actually a pipe, but it is formed directly on the shell.

[0092] It should be noted that since the inner cooling channel 8 or the outer cooling channel 7 is used to introduce cooling medium to dissipate heat to the high-temperature area of ​​the motor (referring to the high-heat-generating components of the motor, such as the stator core and windings) or the unit module 12 in the integrated system 1 of the control system and the motor, the two cooling channels, whether they are coils or through slots, need to be spread as much as possible on the corresponding shell, so that they can cover as many components that need heat dissipation as possible to achieve better heat dissipation.

[0093] according to Figure 5-7 As can be seen, in this example, from inside to outside (diameter direction), the following are the motor (shown in the figure are the motor rotor 9, stator 10, winding 11, and bearing 13), the inner housing 17, the inner cooling channel 8 provided in the gap between the inner housing 17, the unit modules 12 distributed around the outer wall of the inner housing 17, the outer housing 16 provided around the unit modules 12, and the outer cooling channel 7 provided in the gap between the outer housing 16. The inner cooling channel 8 mainly cools the high-temperature areas of the motor, while the outer cooling channel 7 mainly cools the unit blocks 12.

[0094] The motor bearing 13 is used to support the rotating shaft. The main control board is arranged on the end cover 2 as described above. The electrical connection and communication between each unit module 12 and the main control board are achieved through wire connections or connectors.

[0095] like Figure 6 As shown, the center is the motor part, and the figure shows the motor rotor 9, the motor stator 10, and the motor bearing 13. It can be seen from the cross-sectional view that the gap of the outer shell 16 and the gap of the inner shell 17 respectively form an outer cooling channel 7 and an inner cooling channel 8 with through grooves.

[0096] Figure 7 and Figure 8 It shows that the cooling medium inlet 14 and the cooling medium outlet 15 are arranged on the outer wall of the outer shell 16, the cooling medium inlet 14 is connected to the inlet end of the inner cooling channel 8 and the inlet end of the outer cooling channel 7 respectively, and the cooling medium outlet 15 is connected to the outlet end of the inner cooling channel 8 and the outlet end of the outer cooling channel 7 respectively.

[0097] from Figure 7 It can be seen that the unit module 12 is arranged on the outer wall of the inner shell 17. The cooling medium inlet 14 and the cooling medium outlet 15 are arranged on the outer wall of the outer shell 16. The outer wall of the outer shell 16 is formed with heat dissipation teeth 18.

[0098] As can be seen from the above drawings, a gap is provided on the inner shell 17 for setting the inner cooling channel 8, and the inner cooling channel 8 is a coil or a through groove, which is arranged around the inner shell 17 in the gap; and / or a gap is provided on the outer shell 16 for setting the outer cooling channel 7, and the outer cooling channel 7 is a coil or a through groove, which is arranged around the outer shell 16 in the gap.

[0099] In one example, combining Figure 10-12 By setting the pipeline, the cooling medium entering from the cooling medium inlet 14 can be controlled to flow through different paths and then flow out from the cooling medium outlet 15 to achieve heat dissipation. Specifically:

[0100] By setting an internal and external communicating pipe 24, the two ends of which are respectively connected with the inner cooling channel 8 and the outer cooling channel 7 at the same time, specifically: one end of the internal and external communicating pipe 24 is respectively connected with one end of the inner cooling channel 8 and one end of the outer cooling channel 7, and the other end of the internal and external communicating pipe 24 is respectively connected with the other end of the inner cooling channel 8 and the other end of the outer cooling channel 7; then, a first four-way valve 33 is set at the cooling medium inlet 14, and the first four-way valve 33 is respectively connected with the cooling medium inlet 14, the inlet end of the inner cooling channel 8, the inlet end of the outer cooling channel 7 and the inlet end of the internal and external communicating pipe 24; a second four-way valve 34 is set at the cooling medium outlet 15, and the second four-way valve 34 is respectively connected with the cooling medium outlet 15, the outlet end of the inner cooling channel 8, the outlet end of the outer cooling channel 7 and the outlet end of the internal and external communicating pipe 24.

[0101] It should be noted that, at both ends of the pipeline, the end located near the cooling medium inlet 14 is also referred to as the "inlet end" herein, and the end located near the cooling medium outlet 15 is also referred to as the "outlet end" herein.

[0102] Thus, by controlling the communication between the first four-way valve 33 and the second four-way valve 34 and each pipeline, the order in which the cooling medium flows from the cooling medium inlet 14 to the cooling medium outlet 15 is controlled according to the temperature feedback of the high-temperature area of ​​the motor and the unit module 12 of the integrated system 1 of the control system and the motor, so as to achieve more effective heat dissipation. Specifically, Figure 10-12 As shown, according to the above temperature feedback, the following three cooling cycle switching modes are realized:

[0103] The first type: independent cooling: the incoming cooling medium enters the inner cooling channel 8 and the outer cooling channel 7 respectively, so as to cool the unit modules 12 of the motor and the control system respectively. Specifically:

[0104] The first four-way valve 33 is used to control the opening of port 1 25 (i.e., the cooling medium inlet 14), port 2 26 (i.e., the inlet end of the inner cooling channel 8), and port 4 28 (i.e., the inlet end of the outer cooling channel 7), while port 3 27 (i.e., the inlet end of the inner and outer connecting pipe 24) is cut off. The second four-way valve 34 is used to control the opening of port 7 31 (i.e., the cooling medium outlet 15), port 6 30 (i.e., the outlet end of the inner cooling channel 8), and port 8 32 (i.e., the outlet end of the outer cooling channel 7), while port 5 29 (i.e., the outlet end of the inner and outer connecting pipe 24) is cut off, so that the incoming cooling medium enters the inner cooling channel 7 and the outer cooling channel 8 respectively, and then is discharged respectively through the cooling medium outlet 15. The inlet and outlet of the inner cooling channel 8 and the outer cooling channel 7 are independent of each other, so that the incoming cooling medium passes through the inner cooling channel 8 and the outer cooling channel 7 respectively, cooling the unit module 12 of the motor and the control system;

[0105] The second type: Series cooling: The inner cooling channel 8 is connected to the outer cooling channel 7 through a four-way valve to achieve series cooling, wherein:

[0106] (1) One method: The first four-way valve 33 is used to control the opening of port 1 25 and port 2 26, and the disconnection of port 3 27 and port 4 28; the second four-way valve 34 is used to open port 5 29 and port 6 30, and disconnection of port 7 31 and port 8 32, so that the incoming cooling medium first enters the inner cooling channel 8 for heat exchange cooling, then flows through the inner and outer connecting pipes 24, and then enters the outer cooling channel 7 for heat exchange cooling, and then is discharged through the cooling medium outlet 15.

[0107] The inner cooling medium directly contacts the high-heat components and absorbs heat, while the outer cooling medium provides secondary cooling for the inner cooling medium. This design forms an efficient heat dissipation process, in which the cooling medium flows through the cooling motor and then continues to flow through the cooling unit module 12.

[0108] (2) Another method: The first four-way valve 33 is used to control the opening of port 1 25 and port 4 28, and the disconnection of port 2 26 and port 3 27; the second four-way valve 34 is used to open port 6 30 and port 7 31, and the disconnection of port 5 29 and port 8 32, so that the incoming cooling medium first enters the outer cooling channel 7 and then flows through the inner and outer connecting pipes 24, enters the inner cooling channel 8, and is then discharged through the cooling medium discharge main pipe.

[0109] In this embodiment, the cooling medium entering from the cooling medium inlet 14 is preferably a liquid cooling medium. In one example, the cooling medium is fuel, lubricating oil or water supplied from the outside.

[0110] In this embodiment, each of the unit modules 12 is connected to the main control board via a connector or a wire to perform electrical connection and communication interaction.

[0111] In one example, the same unit module 12 is provided with multiple backups, which are connected by connectors or wires. In this way, if a unit module 12 in operation has a problem during operation, it can be promptly switched to the backup unit module 12 for replacement.

[0112] from Figure 7 、 8 As can be seen from Figure 9, heat dissipation teeth 18 are provided at least partially on the surface of the outer shell 16; preferably, heat dissipation channels are formed between the heat dissipation teeth 18 along the air flow direction.

[0113] In one example, the heat dissipation teeth 18 are provided on the upper half of the outer shell 16, and the lower half of the outer shell 16 is provided with a smooth fitting surface 23 for fitting and assembling with the lubricating oil heat exchange box 41. In this way, in situations where there is a lubricating oil heat exchange box 41, such as the aforementioned hybrid power system, this fitting composition can be used to further integrate it, and heat exchange can also be carried out with the lubricating oil heat exchange box 41 to further effectively dissipate heat.

[0114] In one example, the cooling medium inlet 14 and the cooling medium outlet 15 are respectively connected to the bearing cavity where the motor bearing 13 is placed, and are used to transport the cooling medium from the outside to the bearing cavity to dissipate heat to the motor bearing 13, and discharge the cooling medium after heat dissipation through the cooling medium outlet 15. That is, the cooling medium entering from the cooling medium inlet 14, in addition to being cooled and dissipated in the inner cooling channel 8 and the outer cooling channel 7, is also partially used to dissipate heat to the motor bearing 13.

[0115] In other examples, such as Figure 9 As shown, bearing cooling is separated from the cooling from the aforementioned cooling medium inlet 14 and is provided through independent pipelines. In this case, the outer shell 16 is further provided with a motor bearing cooling medium inlet 21 for admitting the motor bearing cooling medium for dissipating heat from the motor bearing 13, and a motor bearing cooling medium outlet 20 for discharging the heat from the motor bearing 13. The motor bearing cooling medium inlet 21 and the motor bearing cooling medium outlet 20 are respectively connected to the bearing cavity in which the motor bearing 13 is positioned. Preferably, the motor bearing cooling medium is fuel, water, or lubricating oil supplied from an external source.

[0116] like Figure 13 As shown, the present invention also provides a hybrid power integrated system, comprising:

[0117] An integrated space 52, which is a box structure having four walls, a cover plate and a bottom plate;

[0118] A hybrid power system is arranged in the integrated space 52. As described above, the hybrid power system comprises at least a gas turbine engine and an integrated system 1 of a control system and a motor.

[0119] The motor in the integrated system 1 of the control system and the motor is driven by the engine to generate and output electrical energy. Preferably, the motor is a high-speed motor.

[0120] By setting the hybrid power system in the integrated space 52, the entire hybrid power integration system can be independently installed and applied to different application scenarios as a whole, such as aircraft (for example, drones, manned aircraft, airships, helicopters, etc.), ships, special vehicles (such as ambulances, fire trucks, police cars, engineering rescue vehicles, military supervision vehicles, etc.) and other equipment, which is conducive to rapid installation and overall maintenance.

[0121] Preferably, the hybrid power system also includes a lubricating oil heat exchanger 41. More preferably, the lubricating oil heat exchanger 41 is assembled and integrated with the control system and motor integrated system 1, further achieving integration and miniaturization. The lubricating oil heat exchanger 41 herein is internally provided with independent fuel lines (the fuel passage) and lubricating oil lines (the lubricating oil passage). The two lines are close together, enabling heat exchange between the fuel and lubricating oil.

[0122] Combine Figure 7 and Figure 10-12 As shown, the cooling medium of the integrated system 1 of the control system and the motor is fuel, which is provided from the fuel tank 36:

[0123] In one example, the fuel tank 36 is connected to the cooling medium inlet through a first supply line 36b, the cooling medium outlet is connected to the exhaust manifold 15a, and the combustion line 39a is connected to the exhaust manifold 15a for providing fuel to the combustion chamber 39 of the gas turbine engine for combustion gas; and / or

[0124] In one example, the fuel tank is connected to the fuel line 42 in the lubricating oil heat exchange box 41 through the second supply line 36c, and the fuel from the second supply line enters the fuel line 42 and exchanges heat with the motor bearing cooling medium in the lubricating oil line 43 of the lubricating oil heat exchange box (41). The fuel after heat exchange with the motor bearing cooling medium is discharged from the fuel line 42. Two branch pipes 42a are set at the discharge port of the fuel line 42, which are respectively connected to the cooling medium inlet and the discharge main pipe. The fuel discharged from the fuel line 42: part of it enters the cooling medium of the integrated system 1 of the control system and the motor from the cooling medium inlet 14, and part of it is collected and discharged to the discharge main pipe 15 of the cooling medium outlet 15.

[0125] The fuel provided by the fuel tank 36 may flow through one or a combination of the following routes:

[0126] (1) The fuel supplied from the fuel tank 36 can pass through the inner cooling channel 8 and the outer cooling channel 7, be discharged from the cooling medium outlet 15, be collected in the discharge manifold 15a, and then be supplied to the combustion chamber 39 through the combustion line 39a for combustion gas;

[0127] (2) The fuel from the fuel tank 36 can also enter the fuel pipeline 42 of the lubricating oil heat exchange box 41 and exchange heat with the motor bearing cooling medium in the lubricating oil pipeline 43 of the lubricating oil heat exchange box 41 (the motor bearing cooling medium in this case is the lubricating oil pipeline). The fuel after heat exchange with the motor bearing cooling medium is discharged from the fuel pipeline 42. Preferably, the fuel discharged from the fuel pipeline 42: part of the fuel enters the cooling medium of the integrated system 1 of the control system and the motor from the cooling medium inlet 14, and part of the fuel is collected and discharged to the discharge main pipe 15a of the cooling medium outlet 15.

[0128] In one example, a fuel recovery line 36a can be provided, connecting the discharge manifold 15a and the fuel tank 36. This allows excess fuel flowing through the discharge manifold 15a, exceeding the fuel requirements of the fuel-burning equipment, to be recovered in the fuel tank 36. Specifically, when the amount of fuel supplied to a fuel-burning equipment exceeds the amount required by that equipment, the excess fuel can be recovered in the fuel tank 26 via the fuel recovery line 36. In this embodiment, the fuel-burning equipment is the combustor of a gas turbine engine.

[0129] In one example, a first three-way valve 15b is provided on the discharge manifold 15a. The first three-way valve 15b connects the cooling medium outlet 15, the combustion line 39a, and the recovery line 36a, respectively, so as to control the flow direction and corresponding flow rate of the fuel collected in the discharge manifold 15a according to actual working conditions.

[0130] exist Figure 13 In the figure, the lubricating oil pipeline 43 in the lubricating oil heat exchange box 41 is connected to the bearing cavity through a pipe to lubricate and dissipate heat for each bearing of the hybrid system. For example, the first bearing cavity 47 and the second bearing cavity 48 are schematically marked in this embodiment, and the pipeline from the lubricating oil heat exchange box 41 to the bearing cavity is provided in series with a lubricating oil filter 44 for filtering the lubricating oil, a lubricating oil pump 45 for pumping, and an oil-gas separator 46.

[0131] from Figure 13As can be seen, the fuel from fuel tank 36 flows through second supply line 36c to fuel line 42 in lubricating oil heat exchange tank 41, where it exchanges heat with lubricating oil in lubricating oil line 43 for heating before discharge. It also flows through first supply line 36b directly into the integrated control system and motor system 1, where it heats up the system before being transported to discharge manifold 15a in combustion chamber 39. A first three-way valve 15b is provided in discharge manifold 15a, allowing control over whether excess fuel needs to be returned to mix with the fuel in fuel tank 36 for cooling, depending on actual operating conditions. The lubricating oil is then transported to lubricate and dissipate heat from the various bearings in the hybrid system before being returned to lubricating oil heat exchange tank 41 for heat exchange with the fuel for cooling.

[0132] After the fuel comes out of the fuel line 42, one branch line 42a can be connected to the discharge main pipe 15a, and another branch line 42a can enter the integrated system 1 of the control system and the motor through the cooling medium inlet 14. At this time, a second three-way valve 42b can also be set at the outlet of the fuel line 42 to control the direction of the fuel discharged from the fuel line 42 according to the actual working conditions.

[0133] Preferably, from Figure 13 It can be seen that a fuel pump 37 for pumping fuel and a fuel filter 38 for filtering the fuel are provided between the combustion chamber 39 and the fuel tank 36 .

[0134] from Figure 13 It can also be seen that at least one air inlet 40 and at least one fan 35 for discharging the gas inside the integrated space 52 are provided on the integrated space 52. The air inlet 40 cooperates with the fan 35 to form a gas flow inside the integrated space 52 to dissipate heat and cool the hybrid power system. Preferably, the fan 35 is an exhaust fan.

[0135] Preferably, the air inlet 40 and the fan 35 are staggered so that the gas flow inside the integrated space 52 can extend its distance as much as possible and form a turbine, thereby enhancing the heat dissipation and cooling effect.

[0136] In one example, the interior of the integrated space 52 is divided into a cold zone 49 and a hot zone 50 by a heat insulation layer 51:

[0137] High-temperature equipment is arranged in the hot zone 50, and the high-temperature equipment at least includes the combustion chamber 39 of the gas turbine engine, and the fuel after passing through the fuel pipeline 42 is provided to the combustion chamber 39 for use as combustion gas; low-temperature equipment is arranged in the cold zone 49, and the low-temperature equipment at least includes the integrated system 1 of the output control system and the motor and the lubricating oil heat exchange box 41.

[0138] In one example, the hot zone 50 and the cold zone 49 are respectively provided with the air inlet 40 and the fan 35 , so that the hot zone 50 and the cold zone 49 are cooled and cooled respectively by air flow.

[0139] Based on the above system, the liquid cooling method of the present invention adopts a two-layer independent cooling medium circulation system. The two-layer independent cooling medium circulation system is designed with two parts, namely the inner cooling channel 8 and the outer cooling channel 7, to evenly distribute the cooling medium in the high-temperature area (each unit module) of the motor and control system of the integrated system 1 of the control system and the motor.

[0140] Thus, the inner cooling medium (the cooling medium flowing through the inner cooling channel 8) directly contacts and absorbs the heat of the high-temperature area of ​​the motor, and the outer cooling medium (the cooling medium flowing through the outer cooling channel 7) cools the unit module 12, forming a double-layer heat dissipation mechanism.

[0141] These two cooling cycles not only improve the heat dissipation efficiency, but also ensure the thermal balance of the entire system through the coordinated work of the inner and outer layers.

[0142] Furthermore, the states of the first four-way valve 33 and the second four-way valve 34 can be dynamically adjusted according to the temperature feedback of the target to be cooled, so as to optimize the flow direction and distribution of the cooling medium and improve the heat dissipation efficiency.

[0143] Furthermore, the aforementioned temperature feedback can be used to adjust the operating parameters of the cooling system, such as pump speed and cooling medium flow rate. For example, if a temperature rise is detected in a high-temperature area of ​​the motor or in a single-mode module 12 within the integrated control system and motor system 1, the system will automatically increase the pump speed and flow rate to provide more cooling medium to absorb and remove heat, thereby achieving optimal cooling. This intelligent control not only improves cooling efficiency but also reduces energy consumption and extends the life of the equipment.

[0144] In addition, since the hybrid power system is arranged in the integrated space 52, the hybrid power system can also be cooled by the gas flow formed by the air inlet 40 of the integrated space 52 and the fan 35, further enhancing the heat dissipation and cooling effect.
