[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Reference below Figure 1-Figure 8 An integrated motor 100 , a compressor, and an air conditioner according to embodiments of the present invention are described.

[0039] like Figure 1 and Figure 2 As shown, the integrated motor 100 according to the first embodiment of the utility model includes: a housing 10 , a motor part and an electronic control part 20 .

[0040] Among them, the shell 10 has a first chamber 11, a second chamber 12, and a connecting hole 13. The motor part is arranged in the first chamber 11, and the electronic control part 20 is arranged in the second chamber 12, so as to realize the motor part (such as: stator, rotor, etc.) and the electronic control part 20 (such as: IGBT module, control board, capacitor, etc.) to realize integration and integrated setting, improve space occupancy, and reduce layout difficulty.

[0041] Specifically, the shell 10 includes a cylindrical part and an installation part arranged on the peripheral side of the cylindrical part. A first chamber 11 is opened on the cylindrical part. The installation part may include a fixing part arranged on the peripheral side of the cylindrical part and a cover body for covering the fixing part. The cover body and the fixing part define a second chamber 12. A fixing surface tangent to the outer peripheral wall of the cylindrical part can be arranged in the fixing part. Threaded holes or installation holes are arranged on the fixing surface for fixing the electronic control part 20. The motor shaft, rotor, stator and other structures of the motor part can be arranged in the first chamber 11 opened in the cylindrical part.

[0042] However, the electric control part 20 generates a large amount of heat during operation, and is arranged on the housing 10 , where the arrangement space is relatively cramped, which also increases the heat accumulation of the electric control part 20 .

[0043] Based on this, the electric control part 20 of the utility model has a cooling module 21 , the cooling medium inlet of the cooling module 21 is connected to the connecting hole 13 , the connecting hole 13 is connected to the external pipeline and is suitable for providing low-temperature cooling medium to the cooling module 21 .

[0044] It should be pointed out that the cooling module 21 can be constructed as a cold plate, and the cooling medium inlet of the cooling module 21 is connected to the external pipeline, which can ensure the sealing reliability and stability of the internal space of the shell 10, and realize forced cooling and heat dissipation of the electronic control part 20 through the cooling module 21. At the same time, auxiliary cooling and heat dissipation can also be realized through the shell 10 to improve the cooling efficiency and cooling effect.

[0045] It can be understood that the cooling medium in the embodiment of the present invention can be a phase change refrigerant, a coolant or other medium.

[0046] According to the integrated motor 100 of the embodiment of the utility model, a first chamber 11 and a second chamber 12 are provided to realize the integrated setting of the motor part and the electronic control part 20, which can effectively improve the space occupancy and reduce the difficulty of layout. Furthermore, a connecting hole 13 is provided, and the cooling module 21 can be connected to the external pipeline through the connecting hole 13 to realize the cooling by the intervention of the cooling medium and the auxiliary cooling by the shell 10, which can effectively improve the cooling efficiency and cooling effect of the electronic control part 20, so as to improve the working reliability and safety of the integrated motor 100.

[0047] In addition, it should be pointed out that the cooling module 21 is fixed in the second chamber 12 of the shell 10, and one side of the cooling module 21 is in contact with the control board, capacitor, etc. of the electronic control part 20 to realize contact heat exchange, and the other side of the cooling module 21 is in contact with the shell 10. The stator, rotor and other motor parts are arranged in the first chamber 11 of the shell 10. The cooling module 21 can also realize heat exchange with the stator to reduce the operating temperature of the integrated motor 100 and further improve the working stability of the integrated motor 100.

[0048] According to some embodiments of the present utility model, a cooling medium pipe interface is provided on the connecting hole 13, and the cooling medium pipe interface is used to be connected to an external pipeline.

[0049] Specifically, the cooling medium pipe interface can integrate structures such as a one-way valve and an on-off valve, and be connected to the external pipeline through the cooling medium pipe interface to ensure the sealing reliability and stability inside the shell 10, and can reduce the installation difficulty of connecting the external pipeline with the connecting hole 13.

[0050] It should be pointed out that one end of the cooling medium pipe interface is constructed as a connecting section, which can extend into the inlet of the connecting hole 13 and can be interference fit or threadedly fastened with the inner wall of the connecting hole 13, and the other end of the cooling medium pipe interface is constructed as an interface section, on which a snap structure, a hoop structure, etc. can be provided to achieve a stable and reliable connection between the cooling medium pipe interface and the external pipeline, and to avoid leakage of the cooling medium in this area.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the second chamber 12 includes a plurality of sub-chambers arranged around the first chamber 11, the electrical control part 20 includes at least one cooling module 21, and the cooling module 21 is arranged in at least one sub-chamber.

[0052] The axis of the cylinder part is defined as the center, and a three-dimensional coordinate system is made with it as the axis as the Z axis. Sub-chambers can be set on the positive side of the X axis, the negative side of the X axis, the positive side of the Y axis, and the negative side of the Y axis. Sub-chambers can also be set at both ends of the Z axis. Each sub-chamber is located in the tangential direction of the cylinder part or at the axial end, so that the layout position of each sub-chamber is more reasonable, the interference probability of the assembly of components inside each of the multiple sub-chambers is lower, and the assembly efficiency is higher.

[0053] Specifically, the electronic control part 20 can be divided into multiple functional parts (such as: capacitor part, electronic control part, etc.) based on function or layout convenience. Each functional part is arranged in a different sub-chamber or a part of the functional parts is arranged in the same sub-chamber, and the other part of the functional parts is arranged in another sub-chamber or multiple sub-chambers. One or more of the multiple functional parts need to be configured with a cooling module 21, so that at least one sub-chamber is provided with a cooling module 21, and the connecting hole 13 is connected to the external pipeline through the cooling medium pipe interface, and the outlet of the connecting hole 13 is used to connect to the cooling module 21. Based on the number of cooling modules 21, one connecting hole 13 can be set to have multiple outlets, or multiple connecting holes 13 can be set, each connecting hole 13 has at least one outlet, so as to realize the cooling medium supply of multiple cooling modules 21, effectively improve the cooling effect and cooling efficiency of the cooling module 21, so as to improve the working stability and reliability of the integrated motor 100.

[0054] Furthermore, the outlet of the communication hole 13 is located in the sub-chamber where the cooling module 21 is disposed.

[0055] It should be pointed out that the outlet of the connecting hole 13 is located in the sub-chamber of the cooling module 21, which means that the connecting hole 13 directly extends into the corresponding sub-chamber, and there is no need to arrange a hose for connection between the two, and it is directly realized through the opening on the shell 10. In other words, the connecting hole 13 is arranged on the side wall of the shell 10, the inlet of the connecting hole 13 is formed on the side wall, and the connecting hole 13 extends toward the sub-chamber, so that the cooling module 21 can be connected to the outlet of the connecting hole 13 in the sub-chamber where it is located, which can reduce the difficulty of connecting the two, reduce the length of the pipeline, and do not need to lead the pipeline out of the sub-chamber, and can also reduce the risk of leakage and improve the cooling stability and reliability.

[0056] Preferably, the connecting hole 13 can be located on one side of the second chamber 12, so that the connecting hole 13 is arranged adjacent to the second chamber 12, which can reduce the extension length of the connecting hole 13 to reduce the processing cost, and the position of the connecting hole 13 is more reasonable, and the position of the inlet end of the connecting hole 13 of the cooling medium pipe structure is more reasonable, which can also improve the convenience of connecting the connecting hole 13 with the external pipeline.

[0057] Specifically, the connecting hole 13 is formed on the fixed part, and is formed on the solid part of the fixed part for defining the second chamber 12, so that the connecting hole 13 is adjacent to the second chamber 12 and is located on one side of the second chamber 12. On the one hand, the connecting hole 13 is formed on the fixed part, which is more convenient for connection with external pipelines than when it is formed on the cylindrical part; on the other hand, the distance between the connecting hole 13 and the second chamber 12 is shorter, and the opening length of the connecting hole 13 can be shorter, which can effectively reduce the processing difficulty of the shell 10 and reduce the processing cost.

[0058] See also Figure 3 and Figure 4 As shown, further, the integrated motor 100 further includes: a discharge hole 14 , the inlet of the discharge hole 14 is located in the sub-chamber where the cooling module 21 is provided, and the outlet of the discharge hole 14 is located in the first chamber 11 .

[0059] Specifically, the connecting hole 13 is formed as a first part of the cooling medium flow channel, the cooling module 21 is constructed as a cold plate and a second part of the cooling medium flow channel is opened on the cold plate, and the discharge hole 14 is formed as a third part of the cooling medium flow channel. The first part, the second part and the third part of the cooling medium flow channel constitute a complete cooling medium flow path. The cooling medium provided by the external pipeline is supplied from the first part of the cooling medium flow channel to the second part of the cooling medium flow channel, and fully exchanges heat with the electronic control part 20 in the second part of the cooling medium flow channel to reduce the operating temperature of the electronic control part 20. After improving heat accumulation, the cooling medium that has completed the heat exchange flows out from the third part of the cooling medium flow channel to the first chamber 11, and can flow back to the system together with the motor return liquid in the first chamber 11 (based on the use environment of the motor, it can flow back to the cooling system cavity or the high-temperature cooling medium cavity of the compressor).

[0060] Therefore, by setting the discharge hole 14, the cooling medium can flow back together with the motor return liquid, and there is no need to set a cooling medium discharge section pipeline, which simplifies the structure, reduces costs, and reduces the difficulty of connection.

[0061] It should be pointed out that in some optional forms, the integrated motor 100 can form a part of equipment such as a compressor, and a refrigerant can flow inside the integrated motor 100. At this time, the cooling medium flowing through the cooling module 21 can also be constructed as a refrigerant so that the refrigerant can be combined and discharged into the refrigerant cavity; in other optional forms, the integrated motor 100 can be used as a power source to drive other components, and coolant and cooling oil can flow inside the integrated motor 100. The motor shaft of the integrated motor 100 directly outputs power, and the cooling medium of the cooling module 21 is also constructed as coolant, cooling oil, etc., and can be synchronously refluxed to the cooling medium cavity.

[0062] Furthermore, if Figure 5 and Figure 6As shown, the cooling module 21 includes: a cold plate 211 and a pipe assembly. The pipe assembly is located at both ends of the cold plate 211 and defines an inlet of the cooling module 21 and an outlet of the cooling module 21. A heat exchange flow channel is formed in the cold plate 211.

[0063] Specifically, a cooling inlet joint may be provided at the outlet of the connecting hole 13 , and a cooling outlet joint may be provided at the inlet of the discharge hole 14 , and they are connected to the inlet of the cooling module 21 through the cooling inlet joint, and the cooling outlet joint is connected to the outlet of the cooling module 21 .

[0064] That is to say, the first part of the cooling medium flow channel (the outlet of the connecting hole 13) is connected to the second part of the cooling medium flow channel (i.e., the inlet of the cooling module 21) through the cooling outlet joint, the second part of the cooling medium flow channel (i.e., the outlet of the cooling module 21) is connected to the third part of the cooling medium flow channel (i.e., the inlet of the discharge hole 14), and the outlet of the discharge hole 14 is located in the first chamber 11.

[0065] In this way, the cooling module 21 and the connecting hole 13 realize refrigerant exchange through the cooling inlet joint, and the cooling module 21 is connected to the discharge hole 14 through the cooling outlet joint, which can reduce the sealing surface area to reduce the leakage risk, improve the sealing stability and reliability, and improve the cooling stability and safety.

[0066] like Figure 8 As shown, a first heat exchange surface a and a second heat exchange surface b in a stepped distribution are provided on the side of the cold plate 211 away from the shell 10. The first heat exchange surface a is used for exchanging heat with the first device 22 of the electronic control part 20, and the second heat exchange surface b is used for exchanging heat with the second device 23 of the electronic control part 20.

[0067] Specifically, combined Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, according to the electric control part 20 of the utility model, it can include: a first device 22, a second device 23 and a connecting row 24, such as: an inverter and a rectifier bridge, the cold plate 211 is provided with a first heat exchange surface a and a second heat exchange surface b arranged in a step-like manner on the first side, and the opposite second side is in contact with the housing 10 and is suitable for auxiliary heat dissipation of the stator, the first heat exchange surface a is used for heat exchange with the first device 22, the second mounting surface b is used for heat exchange with the second device 23, and the first device 22 can form a first mounting surface on the side away from the first heat exchange surface a, and the second device 23 can form a second mounting surface on the side away from the second heat exchange surface b, the first mounting surface and the second mounting surface are arranged in the same plane, and the connecting row 24 is arranged on the side of the first device 22 and the second device 23 away from the cold plate 211, that is, it is connected to the first device 22 on the first mounting surface and connected to the second device 23 on the second mounting surface.

[0068] Among them, the first heat exchange surface a and the second heat exchange surface b are arranged adjacent to each other so that a height difference is formed between the first heat exchange surface 131 and the second heat exchange surface 132. The first heat exchange surface a and the second heat exchange surface b can be arranged in a stepped manner. The first device 22 is set on the first heat exchange surface a, and the first device 22 is fitted with the first heat exchange surface a. When the first device 22 generates heat during operation, the first device 22 can exchange heat through the first heat exchange surface a to lower its own temperature, prevent the temperature of the first device 22 from being too high and unable to work normally, and reduce safety hazards. At the same time, the fitting method can achieve the improvement of the heat exchange effect between the first device 22 and the first heat exchange surface a while allowing the first heat exchange surface a to support the first device 22, so as to facilitate the positioning and installation of the first device 22.

[0069] Furthermore, the second device 23 is installed on the second heat exchange surface b, and the second device 22 is fitted with the second heat exchange surface b. When the second device 23 generates heat during operation, the second device 23 can exchange heat through the second heat exchange surface 1 to lower its own temperature, thereby preventing the second device 23 from being unable to work normally due to excessively high temperature, and reducing safety hazards. The fitting method can improve the heat exchange efficiency between the second device 23 and the second heat exchange surface b, and at the same time, the second heat exchange surface b can support the second device 23, thereby facilitating the positioning and installation of the second device 23.

[0070] Since there is a height difference between the first device 22 and the second device 23 in the first direction (i.e., the height of the first device 22 in the first direction is different from the height of the second device 23 in the first direction), in the related art, there is a height difference between the upper surfaces of the first device 22 and the second device 23, which is inconvenient for arranging the connection row 24.

[0071] Based on this, the present application allows the first mounting surface of the first device 22 and the second mounting surface of the second device 23 to be arranged coplanarly, thereby improving the installation convenience of the connecting row 24, and the cold plate 211 can exchange heat between the first device 22 and the second device 23 to prevent the temperature of the first device 22 and the second device 23 from being too high.

[0072] In some embodiments of the present invention, the first device 22 can be configured as a rectifier bridge, and the second device 23 can be configured as an inverter. Since the height of the rectifier bridge is greater than the height of the inverter, the height of the second heat exchange surface b is greater than the height of the first heat exchange surface a, so that the first mounting surface and the second mounting surface can be arranged coplanarly.

[0073] Combination Figure 5 and Figure 8 In some embodiments of the present invention, the electric control part 20 further includes a connecting row 24, which is arranged on a side of the first device 22 and the second device 23 away from the cold plate 211 and is respectively connected to the first mounting surface and the second mounting surface.

[0074] Specifically, the cold plate 221 and the first device 22 and the second device 23 arranged on the cold plate 221 can be assembled in a vertical installation manner, and the connecting row 24 is used to electrically connect the first device 22 and the second device 23, wherein the connecting row 24 is respectively connected to the first mounting surface and the second mounting surface. Since the first mounting surface and the second mounting surface are arranged coplanarly, the connecting row 24 can be arranged in a planar manner to ensure the structural flatness of the connecting row 24, reduce the length of the connecting row 24, reduce the stray inductance, and facilitate the arrangement and production and processing of the connecting row 24.

[0075] like Figure 8 As shown, the first heat exchange surface a and the second heat exchange surface b are arranged in parallel, which is conducive to ensuring that the first mounting surface and the second mounting surface are arranged in parallel, thereby facilitating the coplanar arrangement of the first mounting surface and the second mounting surface.

[0076] Among them, the distance between the first heat exchange surface a and the second heat exchange surface b in the first direction is defined as L, so that the height difference between the first heat exchange surface a and the second heat exchange surface b can be adapted to the height difference between different types of first components 22 and second components 23. The specific numerical setting of L can be determined according to the height difference between the first component 22 and the second component 23, and no specific limitation is made here.

[0077] See also Figure 6 and Figure 7 As shown, the tube assembly includes: an inlet tube 212 and a liquid outlet tube 213, one end of the inlet tube 212 is connected to the outlet of the connecting hole 13, the other end of the inlet tube 212 is connected to the inlet of the cold plate 211, one end of the outlet tube 213 is connected to the outlet of the cold plate 211, the other end of the outlet tube 213 is connected to the inlet of the discharge hole 14, and a positioning portion 214 is also provided on the tube assembly, and the positioning portion 214 is provided on the inlet tube 212 and / or the outlet tube 213.

[0079] Furthermore, a positioning portion 24 is provided on the tube assembly, and the positioning portion 24 can be positioned and cooperated with the shell 10 to facilitate the assembly of the tube assembly and ensure the installation accuracy of the tube assembly. At the same time, since the tube assembly is a part of the electronic control part 20, the positioning and installation of the electronic control part 20 can be achieved, ensuring the installation accuracy of the electronic control part 20 and avoiding the assembly of other components inside the integrated motor 100 due to poor installation accuracy of the cold plate 211.

[0080] like Figure 7 As shown, in some embodiments of the present invention, the tube assembly includes: a liquid inlet tube 212 and a liquid outlet tube 213 , and the positioning portion 24 is disposed on at least one of the liquid inlet tube 212 and the liquid outlet tube 213 .

[0081] In other words, the positioning portion 24 can be arranged on the liquid inlet pipe 212, so that the liquid inlet pipe 212 is positioned and matched with the shell 10, the liquid inlet pipe 212 is connected to the cold plate 211, and the cold plate 211 is connected to the liquid outlet pipe 213, so that the cold plate 211 and the liquid outlet pipe 213 can be positioned and matched with the shell 10 through the liquid inlet pipe 212, thereby improving the installation accuracy of the electronic control part 20, facilitating processing and production, and improving the connection stability and reliability.

[0082] Exemplarily, the liquid inlet pipe 212 can have a cooling inlet joint, the liquid outlet pipe 213 can have a cooling outlet joint, and the cooling outlet structure is formed as a positioning portion 24, the positioning portion 24 is generally rectangular, and a rectangular positioning groove is provided on the outlet area corresponding to the connecting hole 13 and the inlet area of ​​the discharge hole 14, the positioning block 24 is fixed to the rectangular positioning groove, and the two can be fastened by a threaded structure, and sealing gaskets, sealing rings and other structures can be provided on the contacting surfaces of the two, and the joint is opened in the central area of ​​the positioning portion 24, and the joint is concave or convex on one side of the positioning block 24 facing the rectangular positioning groove, and the joint is connected to the connecting hole 13 or the discharge hole 14 by concave-convex matching, which can reduce the sealing surface area while improving the connection reliability and sealing performance.

[0083] like Figure 3 As shown, the outlet of the communication hole 13 is located at one corner area of ​​the sub-chamber, and the inlet of the discharge hole 14 is located at another corner area of ​​the sub-chamber.

[0084] Specifically, the second chamber 12 includes a fixing portion and a shell, the fixing portion is formed as a plurality of plates extending radially or axially relative to the cylindrical portion, the plurality of plates surround a chamber, and the shell cover is arranged on the chamber to define the second chamber 12, the structure of each sub-chamber is substantially the same, and a fixing surface is arranged on each fixing portion, the fixing surface is tangent to the outer peripheral wall of the cylindrical portion to ensure the flatness of the fixing surface, improve the installation convenience and fixing stability of the electronic control part 20, and the outlet of the connecting hole 13 is arranged adjacent to a corner area of ​​the rectangular fixing surface, and the inlet of the discharge hole 14 is arranged adjacent to another corner area of ​​the rectangular fixing surface, so as to separate the connecting hole 13 and the discharge hole 14.

[0085] That is, the sub-chamber is generally rectangular, the outlet of the connecting hole 13 is located in the sub-chamber and at one corner area of ​​the rectangle, and the inlet of the discharge hole 14 is located in the sub-chamber and at another corner area of ​​the rectangle, so that the outlet of the connecting hole 13 is separated from the inlet of the discharge hole 14 to avoid interference between the cooling outlet joint and the cooling inlet joint, reduce the connection difficulty, and avoid local warping after the cooling module 21 is arranged, so as to improve the flatness of the overall arrangement of the electric control part 20. Furthermore, the two corner areas are located in the diagonal direction, such as Figure 3 As shown, one corner is the left front end corner, and the other corner is the right rear end corner, so that the length of the second part of the cooling medium flow channel on the cooling module 21 can be set longer. The longer cooling medium flow channel corresponds to a larger heat exchange area, which can further improve the temperature regulation effect of the electronic control part 20 and effectively reduce the temperature of the electronic control part 20.

[0086] The cooling module 21 may be constructed as a cold plate, and an annular cooling medium flow channel or a serpentine cooling medium flow channel may be provided on the cold plate to increase the cooling medium flow channel length and heat exchange area, thereby improving the cooling effect and cooling efficiency of the cooling module 21 .

[0087] In summary, according to the integrated motor 100 of the embodiment of the utility model, the first part of the cooling medium flow channel and the third part of the cooling medium flow channel are formed on the shell 10, and the second part of the cooling medium flow channel is opened on the cooling module 21, and is connected to the external pipeline through the cooling medium pipe interface to ensure the sealing reliability of the first chamber 11 and the second chamber 12 inside the shell 10. At the same time, the cooling module 21 is connected to the connecting hole 13 and the discharge hole 14 through the cooling inlet joint and the cooling outlet joint to realize the cooling medium exchange. The connection inside the second chamber 12 can reduce the pipeline length and effectively reduce the sealing surface area, thereby reducing the risk of leakage. The cooling medium that has completed cooling can be discharged into the first chamber 11 through the discharge hole 14 (that is, the third part of the cooling medium flow channel), and converge with the motor return liquid to the system, which can also further simplify the structure and reduce costs.

[0088] The compressor according to the second embodiment of the utility model includes: the integrated motor 100 in the above embodiment.

[0089] Specifically, the compressor may include a compression part and a driving part, and the integrated motor 100 is formed as the driving part and can be used to drive the input shaft of the compression part. The input shaft can be integrated into the motor shaft of the integrated motor 100, and the refrigerant flowing in the shell 10 of the integrated motor 100 can be of the same material as the refrigerant used for cooling by the cooling module 21, and a complete flow path can be formed through the motor return liquid to improve the working stability and reliability of the compressor.
