Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a heat pipe guide vane motor and a ducted fan. Background Art

[0002] The heat pipe guide vane motor is designed for the electrification development needs of aircraft, flying cars and electric vehicle propulsion systems. It combines the characteristics of aviation gas turbine engines and automotive electric power technology to achieve interdisciplinary research and technological innovation. The motor is designed with a focus on lightweight and thermal management to ensure optimal performance under various working conditions. By adopting an integrated design and thermal management of the motor and impeller (fan or compressor), it can effectively control the airflow, optimize heat exchange efficiency, and reduce energy loss. In addition, the motor is also highly adaptable and reliable, and can meet the operating requirements of aircraft, flying cars and electric vehicles in extreme environments. Through this cross-border integration of technology, the thermal management guide vane motor provides new ideas and solutions for the development of high-power density electric propulsion systems.

[0003] In the related art, when the heat pipe guide vane motor dissipates heat from the stator, its heat dissipation structure is usually arranged on one axial side of the stator. For example, the existing patent document CN113098177B discloses a stator heat dissipation structure for an inner rotor motor, the stator heat dissipation structure includes a stator coil heat-conducting component arranged on one axial side of the iron core, the stator coil heat-conducting component includes a first stator coil heat-conducting component and a second stator coil heat-conducting component, the first stator coil heat-conducting component is adjacent to the iron core and covers the stator coil along the circumferential direction of the stator, and the first stator coil heat-conducting component extends in the axial direction of the stator, the second stator coil heat-conducting component extends radially and is arranged on the radial outside of the first stator coil heat-conducting component, the second stator coil heat-conducting component is in contact with or connected to or integrally formed with the first stator coil heat-conducting component, a through hole is provided on the support arm, the second stator coil heat-conducting component is arranged in the through hole, and the second stator coil heat-conducting component is a heat pipe.

[0004] Since the motor stator heat dissipation structure of this patented technology only has the stator coil heat-conducting component on one axial side of the iron core, the heat at the other end of the motor will flow to the middle of the motor and the stator coil heat-conducting component. The flowing heat will also easily cause secondary thermal damage to the motor stator. In application practice, it was found that the overall output power density of the motor of this patented technology has certain limitations.

[0005] Therefore, it is urgent for researchers in this field to develop a heat pipe guide vane motor with efficient heat dissipation. Summary of the invention

[0006] In view of this, in order to solve the above-mentioned problems, an embodiment of the present invention provides a heat pipe guide vane motor, which has one end connected to the stator core and the other end connected to a heat dissipation support on a condensing component in the casing. The heat generated in the stator core is directly transferred to the condensing component in the casing through the heat dissipation support and dissipated, thereby improving the heat dissipation path of the motor in the prior art and avoiding the technical problem of secondary damage caused by the flow of heat.

[0011] According to the heat pipe guide vane motor of some embodiments of the present application, the cooling assembly also includes a plurality of winding heat sinks extending along the axial direction of the stator core, and each of the winding heat sinks is sandwiched between two adjacent stator windings.

[0035] Several embodiments of the present application will be disclosed below with diagrams to clearly and completely describe the technical solution of the present application, which constitute a part of the specification of the present application and are used to provide a further understanding of the present invention. The schematic embodiments and descriptions of the present invention are used to explain the present invention and do not constitute an improper limitation on the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0036] In this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the statement "comprise one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The term "several" may include 1, or any other positive integer.

[0037] The technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] The following contents are all examples of specific implementation processes provided for describing in detail the technical solutions to be protected by this application. However, this application may also be implemented in other ways different from the descriptions herein. Persons skilled in the art may, under the guidance of the concepts of this application, adopt different technical means to implement this application. Therefore, this application is not limited to the specific embodiments below.

[0039] Figure 1 The three-dimensional structure of a ducted fan 300 according to an embodiment of the present invention is shown, comprising a heat pipe guide vane motor 100 and a fan 200, wherein the fan 200 is fixedly connected to the power output end of the rotor shaft of the heat pipe guide vane motor via a hub; a second space 14 enclosed by the inner wall surface 12 of the casing 1 of the heat pipe guide vane motor is the duct space of the ducted fan, and the motor body 2 and the fan 200 are stably supported and arranged in the duct space via a heat dissipation support member 3.

[0040] The following is combined with Figure 2-7 A heat pipe guide vane motor 100 with high heat dissipation efficiency according to an embodiment of the present application is described.

[0041] See also Figure 1 A heat pipe guide vane motor 100 in an embodiment of the present application includes a casing 1, a motor body 2 located in a space enclosed by the casing, and a cooling component for cooling the motor body, wherein the cooling component includes a heat dissipation support 3.

[0042] Among them, combined Figure 2 As shown, the casing 1 includes an outer wall surface 11 and an inner wall surface 12, and a first space 13 is formed between the outer wall surface 11 and the inner wall surface 12. The first space 13 is an annular space, and a condensation component 15 is arranged in the annular space. The condensation component 15 is used to cool the casing 1 and quickly cool the heat transferred from the motor body 2, thereby improving the heat dissipation efficiency and thermal power density of the heat pipe guide vane motor.

[0043] It is understandable that the condensation component 15 refers to a cooling pipe with coolant passing through it, or other structural parts that can achieve heat exchange. There is no limitation here, as long as it can quickly transfer the heat from the motor body and the heat of the casing itself.

[0044] The embodiment of the present application fixes one end of the heat dissipation support 3 of the cooling assembly inside the stator core 21 of the motor body 2, and fixes the other end to the casing 1, and connects it to the condensation component 15 in the first space 13 of the casing, so that a large temperature difference is formed at both ends of the heat dissipation support, which is beneficial to ensure that the heat generated by the motor body is quickly transferred through the heat dissipation support 3, thereby improving the heat dissipation effect of the heat pipe guide vane motor.

[0045] It is understandable that the heat dissipation support 3 of the cooling assembly can be constructed as a heat exchange tube and a shell, and the heat exchange tube is embedded in the shell. In this way, the shell can protect the heat exchange tube to a certain extent. At the same time, the motor body 2 is connected and fixed to the casing 1 through the heat dissipation support 3, thereby enhancing the structural stability of the motor body 1; in particular, the heat exchange tube and the shell are made of graphene material, so that the heat dissipation support has high strength and very light weight, and has thermal conductivity far exceeding that of ordinary thermal conductive materials (such as ceramics and copper), and cooperates with the temperature difference between the condensation component and the cooling air, so that the heat inside the motor can be dissipated more effectively. Compared with the existing heat pipe guide vane motor, the application of motor housing fins is reduced, and the heat pipe guide vane motor has better guarantee of more efficient heat transfer performance and lightweight.

[0046] Of course, the heat dissipation support member 3 may also be constructed as other heat exchange structures, such as a heat exchange tube having coolant or other heat exchange medium passing therein.

[0047] Please continue reading Figure 2As a preferred embodiment, the heat dissipation support member 3 includes a plurality of first heat dissipation members 31 and a plurality of second heat dissipation members 32, and one end of each of the first heat dissipation members 31 and the second heat dissipation members 32 is respectively arranged at the two ends of the stator core and fixedly connected in the stator core. In this way, the heat in the stator core, especially the heat generated at the two axial ends of the stator, can be quickly transferred out through the first heat dissipation members 31 and the second heat dissipation members 32, and at least one of the other ends of the first heat dissipation members 31 and the second heat dissipation members 32 is further fixedly connected to the condensation component 15 of the casing 1, thereby further improving the heat dissipation efficiency of the heat pipe guide vane motor 100.

[0048] It should be noted that at least one of the other ends of the so-called first heat sink 31 and the second heat sink 32 is connected to the condensing member 15 of the housing 1, that is, the transfer path for the first heat sink and the second heat sink to quickly transfer the heat in the stator core to the condensing member 15 can be realized in a variety of ways, such as Figure 2 The other ends of the first heat sink 31 and the second heat sink 32 are respectively fixedly connected to the condensing member 15 of the housing 1; or Figure 4 The other end of the second heat sink 32 is first connected to the first heat sink 31 and then connected to the condensing member 15 of the housing 1; or Figure 5 The other end of the first heat sink 31 is connected to the second heat sink 32 first and then to the condensing member 15 of the housing 1 .

[0049] In some embodiments, Figure 8 As shown, the number of the first heat sink 31 and the second heat sink 32 are both two, and they are distributed 180° around the motor body 2. The projection 32' of the second heat sink is perpendicular to the first heat sink 31. In this way, the heat dissipation support members are staggered in the second space, which improves the stable support of the motor and facilitates the heat transfer, thereby ensuring the heat dissipation efficiency of the motor.

[0050] In some embodiments, Fig. 9 As shown, the number of the first heat sink 31 and the second heat sink 32 is a natural number greater than 3. Fig. 9 When the number shown is four, and they are evenly distributed in a circular array in the circumferential direction of the motor body 2, the projection 32' of the second heat sink falls between two adjacent first heat sinks 31. In this way, the heat sink support members are arranged in a staggered manner in the second space, which improves the stable support of the motor and facilitates the transfer of heat from the motor, ensuring the heat dissipation efficiency of the motor, and can adapt to the application of slender motors, such as motors with stator outer diameters between 50mm and 70mm.

[0051] In some embodiments, Figure 6As shown, a plurality of protrusions 30 are provided on the outer peripheral wall of the heat dissipation support 3, and the plurality of protrusions 30 are arranged in a continuous wave-shaped array. In this way, the heat dissipation area of ​​the heat dissipation support can be increased, and at the same time, the turning angle of the flowing airflow can be increased, which is beneficial to improving the heat dissipation efficiency of the heat pipe guide vane motor.

[0052] It is understandable that in order to maintain the high propulsion efficiency of the ducted fan, the ratio of the hub to the tip (i.e., the hub-to-tip ratio) of the electric fan should be selected to be as small as possible. However, in the hub-driven fan, the ratio of the hub to the tip limits the diameter of the motor. In the aerodynamic design of the ducted fan, when a smaller hub-to-tip ratio is selected, the thermal power density of the motor will generally decrease. The present application forms an efficient motor thermal management technology through the provision of a heat dissipation support and the design of the outer wall surface shape to improve the thermal power density of the motor, thereby compensating for the problem of reduced thermal power density caused by the selection of a smaller hub-to-tip ratio, and further solving the technical difficulties that exist when a smaller hub-to-tip ratio needs to be selected in the aerodynamic design of the ducted fan.

[0053] In other embodiments, Figure 3 As shown, the cooling assembly of this embodiment also includes a plurality of winding heat sinks 33 extending along the axial direction of the stator core 21, each winding heat sink 33 is sandwiched between two adjacent stator windings 22, one end of the winding heat sink 33 is connected to the first heat sink 31, and the other end is connected to the second heat sink 32, so that the heat generated by the stator winding can be quickly transferred to the first heat sink 31 and the second heat sink 32 through the winding heat sink to achieve heat exchange. In this way, when the temperature of the stator winding 22 is too high, the regional heat dissipation between the two adjacent stator windings can be achieved through the winding heat sink, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0054] It should be noted that the winding heat sink 33 can be constructed as a heat exchange plate / sheet, and the material of the heat exchange plate / sheet can be made of a very light graphene material with good thermal conductivity, and cooperate with the heat dissipation support, the condensation component and the cooling flow airflow of the second space to dissipate the heat inside the motor more effectively. Compared with the existing heat pipe guide vane motor, the application of motor housing fins can be reduced, and the purpose of ensuring that the heat pipe guide vane motor has more efficient heat transfer performance and lightweight can be better achieved. In addition, the installation method of the winding heat sink 33 can be achieved by opening an installation groove on the stator core, each installation groove is located between two adjacent stator windings, and the winding heat sink is installed in the installation groove, which reduces the difficulty of installing the winding heat sink. At the same time, the space gap between the stator windings is fully utilized, and the radial size of the motor will not be affected, which is conducive to achieving efficient heat dissipation of miniaturized motors.

[0055] Of course, the winding heat sink 33 may also be constructed as other heat exchange structures, such as a heat exchange tube with coolant or other heat exchange medium passing through it.

[0056] In some embodiments, Figure 7 As shown, an insulating layer 331 and a heat-conducting layer 332 are provided on the outer peripheral wall of the winding heat sink 33. The heat-conducting layer 332 is in close contact with the stator winding 22. The provision of the heat-conducting layer 332 reduces the contact thermal resistance between the stator winding 22 and the winding heat sink 33, which is beneficial to improving the heat dissipation efficiency of the heat pipe guide vane motor.

[0057] For example, the thermal conductive layer 332 may be a thermal interface material (TIM), which may include a thermal conductive gasket, which is a sheet material prepared by heating and curing with a polymer material as a matrix and fillers and additives having high thermal conductivity.

[0058] In some embodiments, the thermal interface material may include thermally conductive silicone grease, which is generally prepared by mixing and degassing a high thermally conductive solid as a filler and a liquid with good fluidity and a certain viscosity as a matrix.

[0059] In some embodiments, the thermal interface material may include a thermally conductive gel, the mechanism of action of which is to manually or automatically fill uncured liquid polymer into the interface of the electronic device, and then cure it into a thermosetting polymer material under certain conditions, thereby achieving maximum fit between the two phase interfaces and reducing gaps.

[0060] In some embodiments, the thermal interface material may include a ceramic-based thermal interface material. Ceramics have both high thermal conductivity and excellent electrical insulation, and are particularly suitable for fields requiring electrical insulation.

[0061] In some embodiments, the thermal interface material may include carbon materials, such as graphene, diamond, and carbon nanotubes, which have been shown to have high thermal conductivity. Therefore, using carbon materials as thermal conductive fillers is expected to significantly improve the thermal conductivity of polymers.

[0062] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0063] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.

[0064] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0065] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
