[0029] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0030] 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 "more than two" includes two or more than two situations.

[0031] In the related art, when the heat pipe guide vane motor 100 dissipates heat from the stator, its heat dissipation structure is usually arranged at the axial end of the stator, which makes it difficult to dissipate the heat in the axial middle area of ​​the stator, resulting in poor heat dissipation effect of the heat pipe guide vane motor 100.

[0032] In this regard, the present application proposes a heat pipe guide vane motor 100 with high heat dissipation efficiency.

[0033] The following is combined with Figure 1-6 A heat pipe guide vane motor 100 with high heat dissipation efficiency according to an embodiment of the present application is described.

[0034] Please refer to Figure 1 The heat pipe guide vane motor 100 with high heat dissipation efficiency includes a rotor portion 10 , a stator portion 20 , a housing 30 and a cooling assembly 40 .

[0035] The rotor part 10 is suitable for being connected to the output shaft in power, for example Figure 1 As shown, the rotor part 10 can be dynamically connected to the rotating shaft of the fan 200, and the rotor part 10 can be sleeved on the rotating shaft to reduce the size occupied by the rotor part 10 in the axial direction and enhance the connection stability between the rotor part 10 and the rotating shaft.

[0036] Of course, in some other implementations, the rotor part 10 can also be dynamically connected to the rotating shaft of the fan 200 by direct connection or other connection methods, which is not limited here.

[0037] For further information, please refer to Figure 1 The stator part 20 is sleeved on the rotor part 10 and a first gap 51 is formed between the stator part 20 and the rotor part 10. In this way, after the stator part 20 is energized to generate a rotating magnetic field, the rotor part 10 can rotate relative to the stator part 20 under the action of the rotating magnetic field, thereby driving the load of the motor to work.

[0038] It can be understood that the setting of the first gap 51 can ensure that the rotor part 10 will not interfere with the stator part 20 when rotating, and the setting of the first gap 51 allows the heat generated by the stator part 20 and / or the rotor part 10 to be dissipated through the first gap 51, that is, the setting of the first gap 51 has a certain heat dissipation effect.

[0039] Please refer to Figure 1 The housing 30 is sleeved on the stator part 20 and a second gap 52 is formed between the housing 30 and the stator part 20. In this way, the housing 30 can protect the stator part 20 and reduce the risk of damage to the stator part 20. It can be understood that the setting of the second gap 52 allows the heat generated by the stator part 20 to be dissipated to the second gap 52, and then the heat is dissipated through the second gap 52, that is, the setting of the second gap 52 has a certain heat dissipation effect.

[0040] Please refer to Figure 2 The cooling assembly 40 is located between two adjacent stator windings 22 of the stator portion 20 .

[0041] In this way, the setting position of the cooling component 40 can make full use of the space between two adjacent stator windings 22, thereby improving space utilization and helping to reduce the impact on the volume of the heat pipe guide vane motor 100, so as to achieve a miniaturized design of the heat pipe guide vane motor 100.

[0042] It can be understood that the cooling component 40 refers to a cooling pipe with coolant passing through it, or other structural parts that can achieve heat exchange, which is not limited here. The cooling component 40 is arranged between two adjacent stator windings 22, so that the cooling component 40 can achieve heat exchange with the stator winding 22 between the two adjacent stator windings 22. In this way, when the temperature of the stator part 20 is too high, the cooling component 40 can be used to achieve heat dissipation in the area between the two adjacent stator windings 22, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0043] Please continue to refer to Figure 1The cooling assembly 40 includes a first heat exchanger 41 and a second heat exchanger 42. The first heat exchanger 41 is connected between the axial end of the stator part 20 and the shell 30. For example, the first heat exchanger 41 can be constructed as a heat exchange tube and a shell. Coolant or other heat exchange medium can flow through the heat exchange tube. The heat exchange tube is embedded in the shell. In this way, the shell can provide a certain degree of protection for the heat exchange tube. At the same time, the stator part 20 can be connected and fixed to the shell 30 through the first heat exchanger 41, thereby enhancing the structural stability of the stator part 20. In particular, the first heat exchanger 41 can dissipate heat from the axial end of the stator part 20 in the radial direction of the stator part 20.

[0044] Of course, the structure of the first heat exchange element 41 may also be other heat exchange structures, which is not limited here.

[0045] The second heat exchange member 42 is connected to the first heat exchange member 41 . The second heat exchange member 42 extends along the axial direction of the stator portion 20 and is used for exchanging heat with the stator portion 20 .

[0046] It can be understood that after the second heat exchange element 42 exchanges heat with the stator portion 20, part of the heat of the stator portion 20 can be transferred to the first heat exchange element 41 along the second heat exchange element 42, that is, part of the heat of the stator portion 20 can be transferred along the axial direction of the stator portion 20 (such as Figure 1 The heat of the stator part 20 is transmitted to the first heat exchanger 41 in the X direction of the stator part 20, and then diffused to the housing 30 and the first gap 51 through the first heat exchanger 41. Meanwhile, another part of the heat of the stator part 20 can also be directly diffused to the first gap 51 through the second heat exchanger 42. In this way, the heat of the axial middle area of ​​the stator part 20 can also be dissipated through the second heat exchanger 42, thereby facilitating the reduction of the temperature of the axial middle area of ​​the stator part 20 and improving the heat dissipation effect of the stator part 20.

[0047] For example, the second heat exchange element 42 can be constructed as a heat exchange tube and a shell. Coolant or other heat exchange medium can flow through the heat exchange tube, and the heat exchange tube is embedded in the shell. In this way, the shell can provide a certain degree of protection for the heat exchange tube. At the same time, the stator part 20 can be connected and fixed to the outer shell 30 through the second heat exchange element 42, thereby enhancing the structural stability of the stator part 20.

[0048] Of course, it should be noted that the structures of the first heat exchange element 41 and the second heat exchange element 42 in the embodiment of the present application may be the same or different, and are not limited here.

[0049] Please continue to refer to Figure 1 The second heat exchange element 42 is connected to a heat dissipation fin that at least partially extends into the first gap 51 and / or the second gap 52 .

[0050] For example, the second heat exchange element 42 is connected to a heat dissipation fin that at least partially extends into the first gap 51. At this time, the heat dissipation fin absorbs the heat in the first gap 51 and transfers the part of the heat to the second heat exchange element 42, and then transfers the heat to the first heat exchange element 41 via the second heat exchange element 42, so that the heat of the rotor part 10 and the stator part 20 can be dissipated in sequence via the first gap 51, the second heat exchange element 42 and the first heat exchange element 41, thereby reducing the temperature in the first gap 51, which is beneficial to improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0051] It should be noted that, in order to ensure the design of the volume size of the heat pipe guide vane motor 100, the first gap 51 is usually designed to be smaller. Therefore, the heat dissipation effect of the first gap 51 itself is poor. In the present application, the problem of poor heat dissipation effect of the first gap 51 itself is taken into consideration. Therefore, a heat dissipation fin that at least partially extends into the first gap 51 is provided to facilitate the heat dissipation in the first gap 51, thereby improving the heat dissipation effect at the first gap 51.

[0052] Alternatively, the second heat exchange element 42 is connected to a heat dissipation fin that at least partially extends into the second gap 52. In this case, the heat dissipation fin has the function of diffusing the heat from the stator part 20 absorbed by the second heat exchange element 42 to the second gap 52, so as to achieve heat dissipation of the stator part 20, thereby reducing the temperature of the stator part 20, which is beneficial to improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0053] Of course, the second heat exchange element 42 may also be provided with heat dissipation fins that at least partially extend to the first gap 51 and heat dissipation fins that at least partially extend to the second gap 52, which can also achieve the same technical effect as above and will not be elaborated here.

[0054] According to the heat pipe guide vane motor 100 with high heat dissipation efficiency of the embodiment of the present application, the cooling assembly 40 is located between two adjacent stator windings 22 of the stator part 20 so as to realize cooling of the area between the two adjacent stator windings 22, and the cooling assembly 40 includes a first heat exchanger 41 and a second heat exchanger 42. The first heat exchanger 41 is connected between the axial end of the stator part 20 and the housing 30, so that the first heat exchanger 41 can dissipate heat to the axial end of the stator part 20 in the radial direction of the stator part 20, and the second heat exchanger 42 is connected to the first heat exchanger 41. The second heat exchanger 42 is connected to the first heat exchanger 41. The heat exchange element 42 extends along the axial direction of the stator part 20 and is used for exchanging heat with the stator part 20; wherein, the second heat exchange element 42 is connected with a heat dissipation fin that at least partially extends into the first gap 51 and / or the second gap 52, that is, the second heat exchange element 42 can realize the heat dissipation of the stator part 20 in the axial direction of the stator part 20, and the second heat exchange element 42 is connected with a heat dissipation fin that at least partially extends into the first gap 51, so that the heat in the first gap 51 and / or the second gap 52 can be dissipated through the second heat exchange element 42, thus, it is convenient to improve the heat dissipation effect of the heat pipe guide vane motor 100.

[0055] In some embodiments, please refer to Figure 2 The stator part 20 includes a stator core 21 and a plurality of stator windings 22 , the stator windings 22 are connected to the stator core 21 , the plurality of stator windings 22 surround the rotor part 10 and are spaced apart on the radial outer side of the rotor part 10 , and the second heat exchanger 42 is connected to the stator core 21 and is located between two adjacent stator windings 22 .

[0056] Therefore, by setting the second heat exchanger 42 between two adjacent stator windings 22, the setting position of the second heat exchanger 42 can make full use of the space between the two adjacent stator windings 22, thereby improving space utilization and helping to reduce the impact on the volume of the heat pipe guide vane motor 100, so as to achieve a miniaturized design of the heat pipe guide vane motor 100.

[0057] It can be understood that the second heat exchange element 42 can be a cooling pipe with coolant passing through it, or other structural components that can achieve heat exchange, which is not limited here. The second heat exchange element 42 is arranged between two adjacent stator windings 22, so that the second heat exchange element 42 can achieve heat exchange with the stator winding 22 between the two adjacent stator windings 22. In this way, when the temperature of the stator part 20 is too high, the second heat exchange element 42 can be used to achieve heat dissipation in the area between the two adjacent stator windings 22, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0058] In some embodiments, the stator core 21 is provided with a mounting groove extending along the axial direction of the stator portion 20 , the second heat exchange element 42 is located in the mounting groove, and in the axial direction of the stator portion 20 , the projection of the second heat exchange element 42 falls within the stator core 21 .

[0059] It can be understood that, in the axial direction of the stator part 20, the projection of the second heat exchanger 42 falls inside the stator core 21, which means that in the axial direction of the stator part 20, the projection of the second heat exchanger 42 does not protrude from the stator core 21. In this way, the setting of the second heat exchanger 42 will not affect the radial dimension of the stator part 20, thereby facilitating the reduction of the radial dimension of the stator part 20, and facilitating the miniaturization design of the heat pipe guide vane motor 100.

[0060] In some embodiments, a water-absorbing material is provided between the inner wall of the mounting groove and the second heat exchange element 42. The water-absorbing material may be a desiccant. Thus, when the second heat exchange element 42 comes into contact with hot air, the desiccant can be utilized to absorb part of the condensed water generated on the surface of the second heat exchange element 42, thereby achieving the effect of drying the mounting groove. In this way, the dryness of the heat pipe guide vane motor 100 can be improved, and the safety of the heat pipe guide vane motor 100 can be improved.

[0061] It is understood that the desiccant in this application is a substance that can absorb moisture in the air, and is usually used to keep the environment dry and prevent items from getting damp. There are many types of desiccant, and they can be selected according to different usage scenarios and needs. The following are some of the main types of desiccant:

[0062] Physical adsorption desiccant: such as silica gel, alumina gel, molecular sieve, activated carbon, bone charcoal, charcoal, mineral desiccant, or activated clay, etc. Its drying principle is to physically adsorb water molecules into its own structure.

[0063] Chemical adsorption desiccants: such as calcium sulfate and calcium chloride, which dry by combining with water to form hydrates; acidic desiccants such as concentrated sulfuric acid, phosphorus pentoxide, anhydrous copper sulfate; alkaline desiccants such as solid caustic soda, lime and soda lime; and neutral desiccants such as anhydrous calcium chloride and anhydrous magnesium sulfate.

[0064] In some embodiments, Figure 3 As shown, the heat dissipation fins include first heat dissipation fins 431 , which are connected to the second heat exchange element 42 , and at least a portion of the first heat dissipation fins 431 extends into the first gap 51 .

[0065] It can be understood that during actual heat dissipation, the first heat dissipation fin 431 absorbs the heat in the first gap 51, and transfers this part of the heat to the second heat exchange element 42, and then transfers it to the first heat exchange element 41 via the second heat exchange element 42, so that the heat of the rotor part 10 and the stator part 20 can be dissipated in sequence via the first gap 51, the first heat dissipation fin 431, the second heat exchange element 42 and the first heat exchange element 41, thereby reducing the temperature in the first gap 51, which is beneficial to improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0066] It should be noted that, in order to ensure the design of the volume size of the heat pipe guide vane motor 100, the first gap 51 is usually designed to be smaller. Therefore, the heat dissipation effect of the first gap 51 itself is poor. In the present application, the problem of poor heat dissipation effect of the first gap 51 itself is taken into consideration. Therefore, the first heat dissipation fin 431 is provided to facilitate the heat dissipation in the first gap 51, thereby improving the heat dissipation effect at the first gap 51.

[0067] In some embodiments, a plurality of first heat dissipating fins 431 are provided, and the plurality of first heat dissipating fins 431 are spaced apart along the axial direction of the stator portion 20 , and the heat exchange areas of the plurality of first heat dissipating fins 431 gradually increase in the airflow direction of the heat pipe guide vane motor 100 .

[0068] It is understandable that if Figure 3 and Figure 4 As shown, when the rotor 10 drives the fan blades to rotate, the flow path of the airflow is as follows: Figure 3 and Figure 4 As shown by the arrowed line segment, as the airflow passes through the first gap 51 , it gradually contacts the stator part 20 and the rotor part 10 , causing the temperature of the airflow to gradually rise. Therefore, the heat dissipation demand for the stator part 20 will also gradually increase.

[0069] In the present application, in the airflow direction of the heat pipe guide vane motor 100, the heat exchange area of ​​multiple first heat sink fins 431 is gradually increased so that in the airflow direction of the heat pipe guide vane motor 100, the heat exchange effect of the first heat sink fins 431 can adapt to the temperature change of the airflow, that is, as the temperature of the airflow gradually rises, the heat exchange effect of the first heat sink fins 431 also gradually increases.

[0070] In this way, the heat exchange effect of the first heat dissipating fins 431 can be adapted to the temperature change of the airflow, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100 .

[0071] In some embodiments, Figure 3 As shown, in the airflow direction of the heat pipe guide vane motor 100 , the density of the plurality of first heat dissipating fins 431 gradually increases.

[0072] It can be understood that when the thickness, cross-sectional area and other dimensions of the first heat dissipating fins 431 remain unchanged, the density of the multiple first heat dissipating fins 431 gradually increases, so that the heat exchange area of ​​the multiple first heat dissipating fins 431 gradually increases, thereby enabling the heat exchange effect of the multiple first heat dissipating fins 431 to adapt to the temperature change of the airflow, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0073] In some embodiments, Figure 4As shown, in the airflow direction of the heat pipe guide vane motor 100 , the heights of the plurality of first heat dissipating fins 431 gradually increase.

[0074] It can be understood that when the thickness, cross-sectional area and other dimensions of the first heat dissipating fins 431 remain unchanged, the heights of the multiple first heat dissipating fins 431 gradually increase, so that the heat exchange area of ​​the multiple first heat dissipating fins 431 gradually increases, thereby enabling the heat exchange effect of the multiple first heat dissipating fins 431 to adapt to the temperature changes of the airflow, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0075] In some embodiments, the heat dissipation fins include second heat dissipation fins 432 , which are connected to the second heat exchange element 42 , and at least a portion of the second heat dissipation fins 432 extends into the second gap 52 .

[0076] Therefore, during actual heat dissipation, the second heat exchange element 42 first exchanges heat with the stator part 20. At this time, the heat accumulates on the second heat exchange element 42. Then, due to the setting of the second heat dissipation fins 432, the heat on the second heat exchange element 42 can be diffused into the second gap 52 through the second heat dissipation fins 432. Then, the airflow will take away the heat in the second gap 52, thereby reducing the temperature of the stator part 20, which is beneficial to improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0077] In some embodiments, a plurality of second heat dissipating fins 432 are provided, and the plurality of second heat dissipating fins 432 are spaced apart along the axial direction of the stator portion 20 , and the heat exchange area of ​​the plurality of second heat dissipating fins 432 gradually increases in the airflow direction of the heat pipe guide vane motor 100 .

[0078] It is understandable that if Figure 3 and Figure 4 As shown, when the rotor 10 drives the fan blades to rotate, the flow path of the airflow is as follows: Figure 3 and Figure 4 As shown by the arrowed line segment, as the airflow passes through the second gap 52 , it gradually contacts the stator part 20 and the rotor part 10 , causing the temperature of the airflow to gradually rise. Therefore, the heat dissipation demand for the stator part 20 will also gradually increase.

[0079] In the present application, in the airflow direction of the heat pipe guide vane motor 100, a plurality of second heat sink fins 432 are arranged with a gradually increasing heat exchange area so that in the airflow direction of the heat pipe guide vane motor 100, the heat exchange effect of the second heat sink fins 432 can adapt to the temperature change of the airflow, that is, as the temperature of the airflow gradually rises, the heat exchange effect of the second heat sink fins 432 also gradually increases.

[0080] In this way, the heat exchange effect of the second heat dissipating fins 432 can be adapted to the temperature change of the airflow, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100 .

[0081] In some embodiments, Figure 5 As shown, in the airflow direction of the heat pipe guide vane motor 100 , the density of the plurality of second heat dissipating fins 432 gradually increases.

[0082] It can be understood that when the thickness, cross-sectional area and other dimensions of the second heat dissipating fins 432 remain unchanged, the density of the multiple second heat dissipating fins 432 gradually increases, so that the heat exchange area of ​​the multiple second heat dissipating fins 432 gradually increases, thereby enabling the heat exchange effect of the multiple second heat dissipating fins 432 to adapt to the temperature change of the airflow, thereby improving the heat dissipation effect of the heat pipe guide vane motor 100.

[0083] In some embodiments, Figure 6 As shown, in the airflow direction of the heat pipe guide vane motor 100 , the heights of the plurality of second heat dissipating fins 432 gradually increase.

[0085] In some embodiments, Figure 2 As shown, the outer surface of the first heat exchanger 41 and / or the second heat exchanger 42 is provided with a heat conducting layer 44, and the heat conducting layer 44 is in contact with the stator part 20. Therefore, the heat conducting layer 44 can be used to reduce the contact thermal resistance between the stator part 20 and the first heat exchanger 41 and / or the second heat exchanger 42, thereby improving the heat dissipation efficiency.

[0086] For example, the heat conductive layer 44 may be a thermal interface material (TIM), which may be used to reduce the contact thermal resistance between the stator portion 20 and the first heat exchange element 41 and / or the second heat exchange element 42 , thereby improving heat dissipation efficiency.

[0089] In some embodiments, the thermal interface material may include: thermally conductive gel, the mechanism of action of the thermally conductive gel is to fill the uncured liquid polymer into the interface of the electronic device manually or automatically, and then cure it into a thermosetting polymer material under certain conditions, so as to achieve maximum fit between the two phase interfaces and reduce gaps.

[0090] In some embodiments, the thermal interface material may include: a thermally conductive phase change material, which can change from a solid state to a liquid state as the temperature changes, and the heat can be removed through the phase change enthalpy generated therein.

[0091] 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.

[0092] In some embodiments, the thermal interface material may include: carbon materials, such as graphene, diamond, and carbon nanotubes, which have been proven to have high thermal conductivity. Therefore, using carbon materials as thermal conductive fillers is expected to significantly improve the thermal conductivity of polymers and prepare high-performance thermal interface materials.

Of course, the heat conductive layer 44 may also be fixed to the outer surface of the first heat exchanger 41 and / or the second heat exchanger 42 by other means, which is not limited here.
