Description

[0001] This invention relates to the field of spacecraft propulsion system controller technology, and in particular to an integrated launch and launch controller structure and heat dissipation control method. Background Technology

[0002] To meet the aviation industry's requirements for a universal, low-cost, and highly reliable start-generator system, an integrated start-generator controller is necessary. This controller converts electrical energy into mechanical energy to start the engine, and then converts the engine's mechanical energy into electrical energy via a generator to provide power to the spacecraft. Aircraft operate under conditions of low air pressure, humidity, and vibration, and the integrated start-generator controller is typically installed in a confined space, resulting in high heat dissipation. Therefore, the integrated start-generator controller requires high structural strength, sealing, electromagnetic compatibility, lightweight design, and excellent heat dissipation.

[0003] Currently, the industry uses the following assembly method: the driver board uses a standard printed circuit board, and the power devices are fixed to the housing or heat sink by applying thermal grease or applying thermally conductive adhesive. This assembly method is not reliable enough in the complex and variable flight conditions of actual working environments, and the overall potting increases the weight of the controller. The greater the weight of the potting, the higher the thermal conductivity of the adhesive, which means an increase in overall cost, while a low thermal conductivity will affect the heat conduction of the power devices. Summary of the Invention

[0004] The main objective of this invention is to propose an integrated starter-generator controller structure and heat dissipation control method, aiming to solve the problem of excessive overall size and weight of existing integrated starter-generator controller structures.

One of the two end faces of the cover opposite to the housing is provided with an annular mounting groove, and the other is provided with a pressing rib. The annular sealing ring is disposed in the annular mounting groove, and the pressing rib is used to press the annular sealing ring.

[0013] Optionally, the outer bottom of the housing is provided with a plurality of spaced heat dissipation fins corresponding to the positions of the plurality of power devices.

[0014] Optionally, the bottom of the outer shell is provided with an air duct cover plate corresponding to the plurality of heat dissipation fins to form a heat dissipation air duct;

[0019] Optionally, the bottom of the housing has a downwardly protruding mounting bracket, the side of the mounting bracket is provided with reinforcing ribs, and the mounting bracket has mounting holes for mounting and fixing the integrated starter controller structure; and / or,

[0020] The integrated starter controller structure also includes multiple temperature sensors, which are located inside the mounting cavity and are configured corresponding to multiple power devices.

[0021] In addition, to achieve the above objectives, the present invention also provides a heat dissipation control method for an integrated starter-generator controller structure. The integrated starter-generator controller structure includes a housing and a drive board. The housing has an open mounting cavity. The drive board includes an aluminum substrate disposed at the bottom of the mounting cavity. Multiple power devices are disposed on the aluminum substrate. A heat dissipation device is disposed at the outer bottom of the housing. A heat dissipation duct is formed on the heat dissipation device. A heat dissipation fan is disposed corresponding to the heat dissipation duct. Multiple heat dissipation fins are disposed in the heat dissipation duct.

[0022] The heat dissipation control method includes:

[0023] Acquire multiple temperature values ​​at multiple temperature acquisition points of the power devices;

[0024] A fan power adjustment strategy is determined based on multiple temperature values ​​and the locations of multiple temperature acquisition points;

Moreover, since multiple power devices are set on the aluminum substrate, there is no need for overall potting, thereby reducing the overall weight of the integrated controller and saving potting costs. In addition, the heat dissipated by the power devices can also be transferred to the bottom of the mounting cavity through the aluminum substrate and then dissipated through the entire housing.

[0050] To meet the aviation industry's requirements for a universal, low-cost, and highly reliable start-generator system, an integrated start-generator controller is necessary. This controller converts electrical energy into mechanical energy to start the engine, and then converts the engine's mechanical energy into electrical energy via a generator to provide power to the spacecraft. Aircraft operate under conditions of low air pressure, humidity, and vibration, and the integrated start-generator controller is typically installed in a confined space, resulting in high heat dissipation. Therefore, the integrated start-generator controller requires high structural strength, sealing, electromagnetic compatibility, lightweight design, and excellent heat dissipation.

[0051] Currently, the industry uses the following assembly method: the driver board uses a standard printed circuit board, and the power devices are fixed to the housing or heat sink by applying thermal grease or applying thermally conductive adhesive. This assembly method is not reliable enough in the complex and variable flight conditions of actual working environments, and the overall potting increases the weight of the controller. The greater the weight of the potting, the higher the thermal conductivity of the adhesive, which means an increase in overall cost, while a low thermal conductivity will affect the heat conduction of the power devices.

[0052] To address the aforementioned problems, this invention provides an integrated starter-generator controller structure. Figures 1 to 5 This is a specific embodiment of the integrated starter controller structure provided by the present invention.

[0053] Please see Figures 1 to 2The integrated controller structure 100 includes a housing 1, a drive board 2, a control board 3, and a cover 4. The housing 1 has an open mounting cavity 11. The drive board 2 includes an aluminum substrate 21 and a plurality of surface mount terminals 22 disposed on the aluminum substrate 21. The aluminum substrate 21 is mounted at the bottom of the mounting cavity 11. A plurality of power devices 23 are disposed on the aluminum substrate 21. The bottom of the control board 3 is connected to the top surface of the plurality of surface mount terminals 22 by screws. The cover 4 is disposed around the periphery of the opening of the housing 1.

[0054] In the technical solution provided by the present invention, by setting the drive board 2 at the bottom of the mounting cavity 11, and then connecting the bottom of the control board 3 to the top surface of the multiple surface mount terminals 22 with screws, the drive board 2 and the control board 3 are arranged vertically, which saves installation space and reduces the overall size and weight of the housing 1. Moreover, since multiple power devices 23 are set on the aluminum substrate 21, there is no need for overall potting, thereby reducing the overall weight of the integrated controller and saving potting costs. In addition, the heat dissipated by the power devices 23 can also be transferred to the bottom of the mounting cavity 11 through the aluminum substrate 21 and then dissipated through the entire housing 1.

[0055] It should be noted that the housing 1 is integrally formed by CNC, casting or die casting, which makes the processing simple, the assembly convenient, the heat dissipation good and the reliability high. In addition, the aluminum substrate can be fixed to the bottom of the housing by fixing screws.

[0056] It is worth mentioning that, in this embodiment, multiple power devices 23 are soldered onto the aluminum substrate 21 by means of surface mount technology, and their heat can be directly conducted to the housing 1 through the aluminum substrate 21; in addition, the surface mount terminals 22 can both carry large current and serve as support for the control board 3.

[0057] Specifically, please refer to Figure 2 and Figure 3 To facilitate the placement of electronic components that generate significant heat, in this embodiment, a localized area at the bottom of the mounting cavity 11 is recessed to form a potting groove 111. The potting groove 111 is used to mount individual electronic components that generate significant heat. These components are fixed by filling the gap between the electronic components and the potting groove 111 with thermally conductive adhesive. In this way, the heat from the electronic components can be transferred to the potting groove 111, i.e., the housing 1, through the thermally conductive adhesive, which is beneficial for the heat dissipation of the electronic components. This also reduces the area of ​​the drive board 2 and the control board 3, thereby reducing the overall size and weight of the product. Furthermore, to ensure that the heat transferred by the aluminum substrate 21 can be efficiently transferred to the bottom of the mounting cavity 11, thermally conductive silicone grease is provided between the aluminum substrate 21 and the bottom of the mounting cavity 11 in this embodiment.

[0058] Specifically, please refer to Figure 1 To ensure good sealing of the integrated starter-generator controller structure 100, in this embodiment, the integrated starter-generator controller structure 100 further includes an annular sealing ring 5. One of the two end faces of the cover 4 opposite to the housing 1 is provided with an annular mounting groove, and the other is provided with a pressing rib 17. The annular sealing ring 5 is disposed in the annular mounting groove, and the pressing rib 17 is used to press the annular sealing ring 5. In this way, it can be ensured that the cover 4 has good sealing performance after being covered by the housing 1. It is worth mentioning that the annular sealing ring 5 can be made of conductive rubber material, which can ensure the sealing performance of the controller while taking into account electromagnetic compatibility.

[0059] It should be noted that if the annular sealing ring 5 is not provided, the gap between the shell and the top cover can also be sealed directly by applying glue (usually in liquid or semi-solid state).

[0060] Specifically, please refer to Figure 4 In order to reduce the volume of the housing 1 while increasing the heat dissipation area, in this embodiment, a plurality of spaced heat dissipation fins 12 are protruded on the outer bottom of the housing 1 corresponding to the positions of the plurality of power devices 23.

[0061] It should be noted that, in this embodiment, the plurality of heat dissipation fins 12 are integrally formed with the housing 1.

[0062] Further, please refer to Figures 3 to 5 The outer bottom of the housing 1 is covered with an air duct cover plate 6 corresponding to the plurality of heat dissipation fins 12 to form a heat dissipation air duct. A cooling fan 7 is provided at one end of the outer bottom of the housing corresponding to the heat dissipation air duct, and the air outlet end of the cooling fan 7 is arranged corresponding to the heat dissipation air duct. In this way, air cooling can be achieved through the formed heat dissipation air duct and the cooling fan 7, further improving the heat dissipation efficiency. It is worth mentioning that in this embodiment, air cooling or natural cooling can be selected according to the actual power of the controller.

[0063] It should be noted that the specific positions of the air duct cover 6 and the cooling fan 7 can be adjusted according to different power requirements or different product layouts.

[0064] Specifically, the side of the housing 1 is provided with a vent valve mounting hole 13 that communicates with the mounting cavity 11. A vent valve 8 is installed on the vent valve mounting hole 13. In this way, the vent valve 8 can balance the pressure difference between the inside and outside of the housing 1, maintain the airtightness of the product, prevent excessive heat generation of local components inside the housing 1, prevent condensation and fogging inside the housing 1, and improve the service life of the controller and its reliability in harsh environments.

[0065] Specifically, in order to facilitate the installation of external wiring for the integrated starter controller structure 100, a grounding mounting hole 14 communicating with the mounting cavity 11 is provided on the side of the housing 1, and a grounding screw 9 is installed on the grounding mounting hole 14.

[0066] Specifically, in order to achieve a universal design for the integrated starter controller structure 100, a connector mounting hole 15 communicating with the mounting cavity 11 is provided on the side of the housing 1. A connector 10 is installed on the connector mounting hole 15. It should be noted that the number of connectors 10 is not specifically limited. In this embodiment, the number of connectors 10 is five.

[0067] Specifically, in order to facilitate the fixing of the integrated starter-generator controller structure 100, and in this embodiment, the bottom of the housing 1 has a downwardly protruding mounting bracket 16, the side of the mounting bracket 16 is provided with reinforcing ribs 161, and the mounting bracket 16 has mounting holes 162 for fixing the integrated starter-generator controller structure 100. In this way, the integrated starter-generator controller structure 100 can be fixed in the required position through the mounting holes 162. In addition, the reinforcing ribs 161 can also increase the strength of the housing 1 and improve the shock resistance of the housing 1.

[0068] Specifically, in order to understand the heating status of the multiple power devices 23 in real time and ensure safe operation, in this embodiment, the integrated generator controller structure 100 further includes multiple temperature sensors, which are disposed in the mounting cavity 11 and are configured corresponding to the multiple power devices 23.

[0069] Furthermore, this invention also provides a heat dissipation control method for an integrated starter-generator controller structure 100, wherein the integrated starter-generator controller structure 100 includes a housing 1 and a drive plate 2. The housing 1 has an open mounting cavity 11. The drive plate 2 includes an aluminum substrate 21 disposed at the bottom of the mounting cavity 11. A plurality of power devices 23 are disposed on the aluminum substrate 21. A heat dissipation device is provided at the outer bottom of the housing 1. A heat dissipation air duct is formed on the heat dissipation device. A heat dissipation fan 7 is provided corresponding to the heat dissipation air duct. A plurality of heat dissipation fins 12 are provided in the heat dissipation air duct. (Reference) Figure 6 This is a flowchart illustrating the first embodiment of the heat dissipation control method for the integrated generator controller structure provided by the present invention.

[0070] The heat dissipation control method of the integrated generator controller structure includes the following steps:

[0071] Step S10: Obtain multiple temperature values ​​at multiple temperature acquisition points of the power devices.

[0072] It should be noted that there is no specific limitation on the method of obtaining multiple temperature values ​​at the temperature acquisition points of the power device. In this embodiment, temperature sensors are set in the mounting cavity for multiple power devices. There is no specific limitation on the number of temperature acquisition points, which can be set according to the user's needs.

[0073] Step S20: Determine the fan power adjustment strategy based on the multiple temperature values ​​and the locations of the multiple temperature acquisition points.

[0074] It should be noted that the fan power adjustment strategy can be set by the user. For example, if multiple temperature values ​​exceed the preset temperature value, the power of all cooling fans can be increased to dissipate heat.

[0075] Step S30: Adjust the power of each cooling fan according to the fan power adjustment strategy.

[0076] It should be noted that there are no specific restrictions on the method of adjusting the power of the cooling fan. In this embodiment, the cooling fan is electrically connected to and controlled by the control board.

[0077] In the first embodiment of the heat dissipation control method for the integrated generator controller structure provided by the present invention, multiple temperature values ​​are obtained from multiple temperature acquisition points of multiple power devices. A fan power adjustment strategy is determined based on the multiple temperature values ​​and the positions of the multiple temperature acquisition points. Then, the power of each cooling fan is adjusted according to the fan power adjustment strategy. Thus, the heat dissipation of the heat sink can be achieved by adjusting the fan power strategy for the heat dissipation of power devices at different locations.

[0078] refer to Figure 7 , Figure 7 This is a flowchart illustrating the second embodiment of the heat dissipation control method for the integrated generator controller structure provided by the present invention.

[0079] Based on the first embodiment described above, the heat dissipation control method for the integrated generator controller structure in this embodiment includes the following in step S20:

[0080] Step S21: When the number of multiple temperature values ​​greater than the preset temperature value is greater than the preset quantity, adjust all the cooling fans to their rated power.

[0081] It should be noted that the preset temperature value is not specifically limited and can be set according to the rated operating temperature of the power device used. For example, the preset temperature can be set to 40℃. The preset number is also not specifically limited. For example, the preset number is 4. When the number of multiple temperature values ​​greater than 40℃ is 5, all the cooling fans are adjusted to their rated power.

[0082] Step S22: When the number of multiple temperature values ​​greater than the preset temperature value is less than the preset quantity, determine the maximum temperature value and the first position of the corresponding temperature acquisition point.

[0083] It should be noted that, for example, when there are 3 temperature values ​​greater than 40°C, the maximum temperature value and the first location of the corresponding temperature acquisition point are determined.

[0084] Step S23: Determine the fan power adjustment strategy based on the maximum temperature value and the first position.

[0085] It should be noted that there is no specific limitation on the fan power adjustment strategy determined based on the maximum temperature value and the first position. For example, after determining the first position, the power of the fan closest to the first position can be adjusted to the rated power.

[0086] In the second embodiment of the heat dissipation control method for the integrated generator controller structure provided by the present invention, when the number of multiple temperature values ​​greater than a preset temperature value is greater than a preset quantity, all the cooling fans are adjusted to their rated power, thereby achieving maximum heat dissipation efficiency to protect the power devices. When the number of multiple temperature values ​​greater than the preset temperature value is less than a preset quantity, the maximum temperature value and the first position of the corresponding temperature acquisition point are determined, and a fan power adjustment strategy is determined based on the maximum temperature value and the first position, thereby realizing two different heat dissipation strategies.

[0087] refer to Figure 8 , Figure 8 This is a flowchart illustrating the third embodiment of the heat dissipation control method for the integrated generator controller structure provided by the present invention.

[0088] Based on the second embodiment described above, the heat dissipation control method for the integrated generator controller structure in this embodiment includes the following in step S23:

[0089] Step S231: Calculate multiple lateral distance values ​​between the centerline of each of the heat dissipation ducts and the first position.

[0090] Step S232: Determine the minimum lateral distance value among the multiple lateral distance values ​​and the target heat dissipation air duct corresponding to the minimum lateral distance value.

[0091] Step S233: Adjust the cooling fan on the target heat dissipation duct to its rated power.

[0092] In the third embodiment of the heat dissipation control method for the integrated generator controller structure provided by the present invention, by calculating multiple lateral distance values ​​between the centerline of each heat dissipation air duct and the first position, the minimum lateral distance value among the multiple lateral distance values ​​and the target heat dissipation air duct corresponding to the minimum lateral distance value are determined. In this way, the target heat dissipation air duct closest to the first position can be determined. Then, the heat dissipation fan corresponding to the target heat dissipation air duct is adjusted to the rated power, so that heat dissipation can be accurately performed on the position of the heat dissipation fin corresponding to the power device with the highest temperature, thereby protecting the power device and saving power consumption.

[0093] It should be understood that the above are merely illustrative examples and do not constitute any limitation on the technical solutions of the present invention. In specific applications, those skilled in the art can make settings as needed, and the present invention does not impose any restrictions on this.
