Description

TECHNICAL FIELD

[0001] The present application relates to a motor assembly, in particular, an assembly with a motor controller and a cold plate, by passing the output copper column through the cold plate to achieve the purposes of cooling and space saving at the same time, and allowing the terminal structure to be reinforced by the combination of the surrounding glue potting and the frame of the cold plate. BACKGROUND

[0002] In recent years, cold plates have been widely used in motor controllers of electric vehicles. Since the motor drive system has a significant impact on the performance of electric vehicles, thermal design should be considered in the early stages of motor controller design and device layout.

[0003] Generally, the aluminum circuit board (Al-PCB) of the motor controller is arranged on the top of the cold plate, and the traditional output terminal is designed as an upward output terminal structure of the aluminum circuit board (Al-PCB). The output terminal structure arranged on the aluminum circuit board is simple. Usually, the output terminal structure is composed of at least three copper columns, and occupies a large amount of space above the cold plate. After the motor controller is combined with the cold plate, the overall thickness of the system will be thick. Moreover, since the output terminal structure arranged above the cold plate is far away from the cold plate, it will cause slow heat dissipation of the terminal and poor cooling effect. Thus, during high-power output, the wire sheath may be melted.

[0004] On the other hand, it is not easy to arrange a reverse terminal output structure for the motor controller combined with the cold plate. The reverse terminal output structure must be connected between the aluminum circuit board on the top surface of the cold plate and the high-voltage lead wire parallel to the bottom surface of the cold plate. That is, the conductive part of the terminal output structure needs to be perpendicular to the aluminum circuit board or the high-voltage lead wire, which is not conducive to assembly by bolts, nuts parallel to the top surface or the bottom surface of the cold plate.

[0005] Therefore, it is necessary to provide an assembly with a motor controller and a cold plate, by passing the output copper column through the cold plate to achieve the purposes of cooling and space saving at the same time, and solve the defects of the known technology. SUMMARY

[0006] The present application aims to provide an assembly with a motor controller and a cold plate, which achieves the purposes of cooling and space saving by passing an output copper column through the cold plate. The output copper column allows for a glue potting around it and is combined with the frame of the cold plate, thereby strengthening the terminal structure. Compared with the combined connection of the conventional output terminal structure by the protrusion of the cold plate or through horizontal screws, the output terminal structure of the present application penetrating the cold plate is more advantageous in reducing the overall thickness of the assembly with the motor controller and the cold plate and improving the heat dissipation efficiency thereof. Furthermore, the formed potting member can also enhance the support strength between the conductive member and the cold plate and improve the heat dissipation efficiency of the output terminal structure. Preferably, the potting member also has a first ring end and a second ring end arranged at two opposite ends, respectively, for clamping the circuit substrate and the cold plate. This not only reduces the overall thickness of the assembled structure, but also enhances the structural strength of the output terminal structure or provides a waterproof function. In the case of multiple output terminal structures arranged closely, the potting member can be integrally formed to strengthen the structural strength of the first ring end, the ring groove and the connecting portion of the output terminal structure. On the other hand, when each terminal is connected to the conductive member by a screw, the screw is tightened along the vertical direction relative to the surface of the cold plate. The connection operation of the two adjacent conductive members and the terminal does not interfere with each other. In this way, the connection operation of the conductive member and the terminal can be simplified. In addition, the lead-out direction of the terminal can be adjusted in cooperation with the terminal seat fixed to the cold plate, providing multiple combination changes while simplifying the assembly process. The present application has industrial applicability and creativity.

Figure 5is a sectional view showing an assembly with a motor controller and a cold plate according to a first embodiment of the present application. Reference is made to Figures 1 to 5 The present application provides an assembly 1 with a motor controller and a cold plate. In the present embodiment, the assembly 1 with a motor controller and a cold plate comprises a cold plate 10, a circuit board 20, at least one terminal block 30, at least one conductive member 40, and at least one terminal 50. The at least one terminal block 30 is spatially and in number relative to the at least one conductive member 40 and the at least one terminal 50. Preferably, but not exclusively, in the present embodiment, three terminal blocks 30 cooperate with three conductive members 40 and three terminals 50 to form three output terminal structures. The following description is made by way of example with a single output terminal structure, but the present application is not limited thereto. In the present embodiment, the cold plate 10 comprises a first surface 11, a second surface 12, at least one through hole 13, an inlet port 14, and an outlet port 15. The first surface 11 and the second surface 12 are top and bottom surfaces, respectively, disposed opposite to each other. Preferably, but not exclusively, the inlet port 14 and the outlet port 15 are disposed on a side wall 16 of the cold plate 10 and communicate with an internal space (not shown) of the cold plate 10, so that a cooling liquid can be delivered through the inlet port 14 and the outlet port 15 for heat exchange. The at least one through hole 13 penetrates the first surface 11 and the second surface 12. In the present embodiment, the circuit board 20 can be, for example, but not limited to, an aluminum circuit board (Al-PCB) comprising a third surface 21 and a fourth surface 22 disposed opposite to each other. In the present embodiment, the fourth surface 22 of the circuit board 20 is attached to the first surface 11 of the cold plate 10 for heat dissipation, but the present application is not limited thereto. In the present embodiment, the circuit board 20 further comprises at least one opening 23 penetrating the third surface 21 and the fourth surface 22. Further, the at least one opening 23 is spatially opposite to the at least one through hole 13 of the cold plate 10. Preferably, but not exclusively, in the present embodiment, the circuit board 20 is fixed to the first surface 11 of the cold plate 10 by screws. The fourth surface 22 of the circuit board 20 is attached to the first surface 11 of the cold plate 10, and the at least one opening 23 of the circuit board 20 and the at least one through hole 13 of the cold plate 10 are aligned and communicate with each other. In the present embodiment, the circuit board 20 further comprises at least one electronic component 24 configured to form a power supply unit. Preferably, but not exclusively, the electronic component 24 is disposed on the third surface 21 of the circuit board 20.

[0059] In the present embodiment, the terminal seat 30 is spatially relative to the opening 23 of the circuit board 20 and the through hole 13 of the cold plate 10. Preferably but not exclusively, the terminal seat 30 is a surface mount terminal, disposed on the third surface 21 of the circuit board 20, and covers the opening 23 of the circuit board 20. Preferably but not exclusively, the terminal seat 30 is a cylindrical cap, including a sealing portion 31 and an annular space 32. After the terminal seat 30 is disposed on the third surface 21 of the circuit board 20 by a surface mount technology, the sealing portion 31 and the annular space 32 are in communication with the opening 23 of the circuit board 20. Preferably but not exclusively, the conductive component 40 is a copper pillar or a hexagonal stud, including a first joint end 41 and a second joint end 42 disposed at two opposite ends. In the present embodiment, the sealing portion 31 and the first joint end 41 are a concave portion and a convex portion that fit with each other. After the terminal seat 30 is fixed on the third surface 21 of the circuit board 20, the first joint end 41 of the conductive component 40 passes through the through hole 13 of the cold plate 10 and is inserted into the sealing portion 31 of the terminal seat 30 to form an electrical connection. The conductive component 40 passes through the through hole 13 but does not contact the cold plate 10 and is spaced apart from the cold plate 10. Preferably but not exclusively, the second joint end 42 of the conductive component 40 includes an internal thread and has an opening facing a direction perpendicular to the second surface 12 of the cold plate 10. In the present embodiment, the conductive component 40 is clamped by the first joint end 41 and the sealing portion 31 of the terminal seat 30, and the second joint end 42 of the conductive component 40 is exposed and protrudes from the second surface 12 of the cold plate 10. Preferably but not exclusively, in the present embodiment, the terminal wire 50 is a high-voltage wire connected to the conductive component 40 and extends along the second surface 12 of the cold plate 10. It is worth noting that the terminal wire 50 parallel to the second surface 12 can be fixed to the second joint end 42 of the conductive component 40 by a screw (not shown). Of course, the clamping mode of the terminal wire 50 and the second joint end 42 of the conductive component 40 can be adjusted according to the actual application requirements, and the present application is not limited in this regard.

[0060] It is worth noting that in the present embodiment, the terminal seat 30 and the conductive component 40 are configured to form an output terminal structure that penetrates the cold plate 10. Compared with the combined connection by the cold plate protrusion or through the horizontal screw in the conventional output terminal structure, the output terminal structure formed by the terminal seat 30 and the conductive component 40 in the present application is more conducive to reducing the overall thickness of the assembly 1 with the motor controller and the cold plate and improving the heat dissipation efficiency.

[0061] Figure 6 FIG. 2 is a perspective structural view showing the assembly with the motor controller and the cold plate according to the second embodiment of the present application from a lower perspective. Figure 7 FIG. 3 is a structural exploded view showing the assembly with the motor controller and the cold plate according to the second embodiment of the present application from an upper perspective. Figure 8is a structure exploded view showing the assembly with motor controller and cold plate of the second embodiment of the present application from below perspective. Figure 9 is a cross-sectional view showing the assembly with motor controller and cold plate of the second embodiment of the present application. In this embodiment, the structure of the assembly with motor controller and cold plate la is substantially similar to the assembly with motor controller and cold plate 1 shown in Figures 1 to 5 , and the same component numbers are used to represent the same components, structures and functions, which will not be repeated here. Reference is made to Figures 6 to 9 . In this embodiment, the assembly with motor controller and cold plate la further comprises a potting member 60 for encapsulating the space formed between the conductive member 40 and the through hole 13 of the cold plate 10. When the terminal holder 30 is mounted on the third surface 21 of the circuit substrate 20 by surface mounting, and the first engaging end 41 is firmly inserted into the sealing portion 31 of the terminal holder 30 to form an electrical connection, the annular space 32 is then communicated with the outside through the through hole 13 of the cold plate 10. In other words, the conductive member 40 does not contact the inner wall of the through hole 13, and the annular space 32 and a portion of the through hole 13 are not occupied by the conductive member 40. In this embodiment, the potting member 60 is formed by filling potting material into the portion of the annular space 32 and the through hole 13 not occupied by the conductive member 40. After the potting material is cured, the potting member 60 is formed between the cold plate 10 and the conductive member 40, thereby providing sufficient structural support between the cold plate 10, the terminal holder 30 and the conductive member 40. Then, the terminal 50 can be firmly and stably fixed to the second engaging end 42 of the conductive member 40. Since the conductive member 40 is isolated from the cold plate 10 by the potting member 60, the terminal holder 30 and the conductive member 40 further combine the potting member 60 to form an output terminal structure, which is more conducive to enhancing the structural strength, providing waterproof function and improving the heat dissipation efficiency. In some embodiments, the potting member 60 is composed of thermally conductive epoxy resin, silicone or other encapsulation materials, but the present application is not limited thereto.

[0062] In this embodiment, the potting component 60 includes a first annular end 61 and a second annular end 62, respectively disposed at two opposite ends of the potting component 60. In this embodiment, the first annular end 61 is spatially relative to and accommodated within the annular space 32 of the terminal block 30. Preferably, but not exclusively, the diameter of the annular space 32 of the terminal block 30 is larger than the diameter of the opening 23 of the circuit board 20 and also larger than the diameter of the through hole 13 of the cold plate 10. The diameter of the opening 23 of the circuit board 20 is equal to the diameter of the through hole 13 of the cold plate 10. In this embodiment, the cold plate 10 further includes an expansion opening 131, which is disposed on the second surface 12 and spatially corresponds to the through hole 13. The through hole 13 is aligned with the expansion opening 131, and the through hole 13 communicates with the outside through the expansion opening 131. Preferably, but not exclusively, the diameter of the expansion opening 131 is larger than the diameter of the through hole 13. This facilitates the filling material to fill the space between the conductive component 40, the annular space 32, and the through hole 13 through the expansion opening 131 to form the potting component 60. Of course, this application is not limited to this. Furthermore, in this embodiment, the diameters of the annular space 32 and the expansion opening 131 are larger than the diameters of the opening 23 and the through hole 13, respectively. After the potting component 60 is formed by the encapsulation operation, the first annular end 61 and the second annular end 62 formed at the two opposite ends of the potting component 60 can be firmly mounted on the third surface 21 and the second surface 12 of the circuit board 20, respectively. In this way, the output terminal structure formed by the terminal block 30 and the conductive component 40 can be firmly combined with the potting component 60 to enhance structural strength or provide waterproof function. Preferably, but not exclusively, the horizontal cross-sections of the annular space 32, the opening 23, the through hole 13, and the expansion opening 131 are circular, and the horizontal cross-section of the conductive component 40 is hexagonal. Of course, the shape of the potting component 60 can be adjusted according to the actual application requirements, and this application is not limited thereto.

This facilitates the potting material to fill the space between the conductive members 40, the annular space 32, and the through holes 13 through the communication channel 17, and thus the potting member 60a is integrally formed.

[0064] Preferably but not exclusively, the diameter of the annular space 32 of each terminal seat 30 is greater than the diameter of each opening 23 of the circuit substrate 20 and greater than the diameter of each through hole 13 of the cold plate 10. The diameter of each opening 23 of the circuit substrate 20 is less than the diameter of each through hole 13 of the cold plate 10. After the potting member 60a is formed by the encapsulation operation, the potting member 60a is integrally formed as a single structure, thereby securely encapsulating the plurality of conductive members 40 passing through the plurality of through holes 13. In this embodiment, after the potting material of the potting member 60a is cured, a plurality of first ring ends 61 and a plurality of connecting portions 63 are formed at opposite ends of the potting member 60a. In this embodiment, the potting member 60a further includes a plurality of annular grooves 64 recessed adjacent to corresponding ones of the plurality of first ring ends 61 and corresponding in space to the plurality of openings 23 of the circuit substrate 20. Since the diameter of the opening 23 of the circuit substrate 20 is less than the diameter of the through hole 13 of the cold plate 10, the first ring end 61 of the potting member 60a is accommodated in the annular space 32 of the terminal seat 30, abuts against the third surface 21 of the circuit substrate 20, and clamps the circuit substrate 20 to be fixed on the first surface 11 of the cold plate 10. Of course, the diameters, shapes, and arrangements of the first ring ends 61, the annular grooves 64, and the connecting portions 63 can be adjusted according to actual application requirements, and the present application is not limited thereto. By the encapsulation of the integrally formed potting member 60a, the output terminal structure formed by the plurality of terminal seats 30 and the plurality of conductive members 40 is securely combined with the circuit substrate 20 and the cold plate 10.

[0065] In this embodiment, the plurality of conductive members 40 are arranged along a first direction (i.e. X-axis direction). Each of the terminal 50 has the high voltage wire 51 extending along a second direction (e.g. Y-axis direction). There is not enough space between two adjacent conductive members 40 for a screw to operate along the X-axis direction. In this embodiment, each of the terminal 50 is connected to the second joint end 42 of the conductive member 40 by a screw 52, wherein the screw is screwed into the corresponding second joint end 42 along a third direction (i.e. Z-axis direction) which is perpendicular to the first direction (i.e. X-axis direction) and the second direction (i.e. Y-axis direction). In this way, the connection of the two adjacent conductive members 40 and the terminal 50 will not interfere with each other. That is, the connection of the conductive members 40 and the terminal 50 is further simplified. Of course, the connection of the conductive members 40 and the terminal 50 can be varied according to the actual application requirements. The present application is not limited thereto, and will not be described hereinafter.

Figure 16 Figure 17 Figure 18 Figure 19 Figures 1 to 5 Figures 15 to 19 ​​​​​In this embodiment, the assembly 1c having the motor controller and the cold plate further includes at least one terminal block 55. The at least one terminal block 55 is fixed to the cold plate 10 and extends along the second surface 12 and one side wall 18 of the cold plate 10. The terminal block 55 is made of, for example, insulating plastic material. In this embodiment, at least one terminal 50a is partially embedded in the at least one terminal block 55 and includes a first lead-out portion 53 and a second lead-out portion 54. The first lead-out portion 53 and the second lead-out portion 54 are exposed from the at least one terminal block 55 and are perpendicular to the second surface 12 and the side wall 18 of the cold plate 10, respectively. In this embodiment, the at least one terminal block 55 further includes a first lead groove 551 and a second lead groove 552. The first lead groove 551 is arranged parallel to the second surface 12 of the cold plate 10 and extends radially outward in an X-shape with the first lead-out portion 53 as the center. Furthermore, the second lead groove 552 is disposed parallel to the side wall 18 of the cold plate 10 and extends radially outward in an X-shape with the second lead-out portion 54 as the center. In other words, the first lead groove 551 and the second lead groove 552 each have lead grooves with four lead-out directions for the user to choose from. Thus, the user can lead at least one terminal 50a out along different directions of the second surface 12 or side wall 18 of the cold plate 10 according to actual application needs, providing diverse combination variations while simplifying the assembly process.

[0067] In this embodiment, after at least one terminal 50a is connected to the second engagement end 42 of the corresponding conductive component 40 by a screw 52, ​​it is allowed to be led out through the first lead-out portion 53 and / or the second lead-out portion 54. When the user selects the first lead-out portion 53 for lead-out, the lead-out wire 531 can be locked to the first lead-out portion 53 by a fastener, and then one of the lead grooves in the four lead-out directions of the first lead groove 551 can be selected for use. Preferably, when multiple terminals 50a need to be led out through the corresponding first lead-out portion 53, the multiple lead-out wires 531 can be selected from the lead grooves in the same lead-out direction in the first lead groove 551, such as... Figure 18 As shown. Similarly, when the user selects the second lead-out section 54 for output, the lead-out wire 541 can be locked to the second lead-out section 54 by the fastener, and then one of the lead grooves in the four output directions of the second lead groove 552 can be selected for use. Preferably, when multiple terminals 50a need to be output from the corresponding second lead-out section 54, the multiple lead-out wires 541 can be selected from the lead grooves in the same output direction in the second lead groove 552, such as... Figure 19 As shown. Of course, in other embodiments, the pairing of the first lead-out portion 53, the second lead-out portion 54, the first lead groove 551, and the second lead groove 552 can be adjusted according to actual application requirements. This application is not limited thereto.

[0068] In this embodiment, the at least one terminal holder 55 further comprises a first mounting hole 553, which is adjacent to the second lead slot 552 and is spatially relative to the second mounting hole 181 on the sidewall 18 of the cold plate 10. The at least one terminal holder 55 can be fixed to the cold plate 10 by means of the first mounting hole 553 and the second mounting hole 181 through the screw 56. Of course, in other embodiments, the manner in which the at least one terminal holder 55 is fixed to the cold plate 10 can be modified according to the actual application requirements. The present application is not limited thereto, and further description is omitted.

[0069] In summary, the present application provides an assembly having a motor controller and a cold plate, which achieves the purposes of cooling and space saving by passing the output copper column through the cold plate. The output copper column allows the surrounding potting and is combined with the frame of the cold plate, thereby strengthening the terminal structure. Compared with the combined connection of the conventional output terminal structure by the protrusion of the cold plate or through the horizontal screw, the output terminal structure of the present application penetrating the cold plate is more conducive to reducing the overall thickness of the assembly having the motor controller and the cold plate and improving the heat dissipation efficiency thereof. Furthermore, the formed potting member can also enhance the support strength between the conductive member and the cold plate and improve the heat dissipation efficiency of the output terminal structure. Preferably, the potting member further has a first ring end and a second ring end disposed at two opposite ends, respectively, for clamping the circuit substrate and the cold plate. In this way, not only the overall thickness of the assembled structure can be reduced, but also the structural strength of the output terminal structure can be enhanced or the waterproof function can be provided. In the case where a plurality of output terminal structures are closely arranged, the potting member can be integrally formed to strengthen the structural strength of the first ring end, the ring groove, and the connecting portion of the output terminal structure. On the other hand, when each terminal is connected to the conductive member by means of the screw, the screw is tightened along the vertical direction relative to the surface of the cold plate. The connection operation of the adjacent two conductive members and the terminals does not interfere with each other. In this way, the connection operation of the conductive member and the terminal can be simplified. In addition, the lead-out direction of the terminal can be modified in cooperation with the terminal holder fixed to the cold plate, thereby providing multiple combinations and simplifying the assembly procedure. The present application has industrial applicability and creativity.

[0070] The present application can be modified by those skilled in the art without departing from the scope of the appended claims.
