Description

Technical Field

[0001] The present invention relates to the field of power electronics technology. Specifically, it relates to an assembly structure of a modular water channel and a power module applicable thereto, which realizes optimized heat dissipation performance of the power module through flexible modular design. Background Art

[0002] In existing in-vehicle power products, a liquid cooling heat dissipation solution is mostly adopted to solve the heat dissipation problem of high-power power supplies. Traditional liquid cooling heat dissipation assembly structures (such as water channel modules) usually adopt the form of castings or sheet metals. Among them, due to limitations in the forming process, the manufacturing size of die-castings is usually large, the manufacturing accuracy is poor, and there are disadvantages such as high costs. And sheet metal parts are limited by the body strength, unable to effectively meet the water channel sealing pressure and prone to deformation.

[0003] On the other hand, since a three-dimensional water channel can provide a higher degree of freedom in device layout and structural design compared to a planar water channel, it has great advantages in high-power density power products. Currently, most water channel components (such as U-shaped) in the market adopt an integrated design and can be formed by die-casting or by profile (bending) technology. However, the width of the coolant cavity of the water channel component is limited by the forming process and cannot be made very narrow, thus unable to further meet the requirement of reducing the module width size. Moreover, in order to make the coolant fully contact the inner wall of the water channel and improve the heat dissipation efficiency, usually traditional water channel modules use isolation fins to divide the flow channel into multiple small flow channels, which increases both the process and the cost, and at the same time increases the flow resistance. In addition, when manufacturing a water channel module by profile bending technology, problems such as stress concentration and deformation are more likely to occur at the bending part, and additional process treatment is required to ensure the accuracy, increasing the process complexity and cost.

[0004] In view of this, how to develop an assembly structure of a modular water channel and a power module applicable thereto, which realizes optimized heat dissipation performance of the power module through flexible modular design, is indeed a topic that the field urgently needs to face. Summary of the Invention

[0005] The object of the present invention is to provide an assembly structure of a modular water channel and a power module applicable thereto. By splitting the independent U-shaped water channel heat dissipation module into linear flow channel components and bending components on both sides and then combining with the front-end component, each component is assembled modularly, and the optimized heat dissipation efficiency of the power module can be flexibly achieved. Among them, the linear flow channel components on both sides can form a flat inner cavity through profile parts, stamped parts or die-cast parts, and the length and width of the cavity are not limited by the forming process, and the size can be adjusted according to actual application requirements. Of course, each linear flow channel component can also be assembled by a side flow channel plate with grooves and a side cover plate. The side flow channel plate and the side cover plate are assembled by friction welding, laser welding, brazing, diffusion welding, electron beam welding or sealing glue fixing connection, which is more conducive to reducing the thickness of the components. Furthermore, the bending component and the front-end component are made of die-cast parts, which can provide sufficient structural support and can be modularly spliced with the linear flow channel components on both sides by friction welding, laser welding, brazing, diffusion welding, electron beam welding or sealing glue fixing connection. On the other hand, when the assembly structure of the modular water channel is applied to the power module, the inner heat dissipation surfaces of the linear flow channel components on both sides can correspond to the two opposite sides of the thermally coupled magnetic components, and the outer heat dissipation surfaces of the linear flow channel components on both sides can be thermally coupled to through-hole power devices or a surface-mounted power device respectively. In addition, the bending component also provides another outer heat dissipation surface for application. Thus, the modular disassembly and connection of the linear flow channel components on both sides and the bending component combined with the front-end component can be flexibly adjusted according to the number, size and arrangement of the heat-generating devices, effectively reducing the development cost and time of the heat dissipation water channel module for developing the applicable power module. Since the structures of the front-end component, the linear flow channel components on both sides and the bending component are all simplified in design, they can be manufactured through multiple forming processes and have a low cost. In addition, the assembly structure of the modular water channel can be hermetically matched with the outer shell through the engaging part of the front-end component, and the engaging part is not limited to trapezoidal shapes and integral circumferential grooves or ridges. The front-end component and the bending component can also be fixed to the casing by screws respectively, and then heat dissipation glue is filled to further enhance the heat dissipation efficiency. The present invention realizes the heat dissipation, installation and fixation and sealing design of the overall water channel module by simply disassembling and connecting the front-end component, the linear flow channel components on both sides and the bending component, without affecting the splicing of other inflow pipes, outflow pipes, bottom plates and top covers. Compared with the traditional single-piece water channel design, the assembly structure of the modular water channel of the present invention has greater versatility, and for heat dissipation scenarios that need to adapt to different lengths and widths, only the sizes of some structural parts need to be changed to achieve low-cost adaptation. It should be understood that the "fitting" or "contact" mentioned in the present invention does not mean direct fitting or direct contact, but also includes leaving a certain air gap or inserting an insulating medium between the two and then fitting or contacting.

Figure 7Schematically shows a vertical cross-sectional structure diagram of a power module in the first embodiment of the present invention. In this embodiment, the present invention provides a power module 2, for example, applied to an on-vehicle charger. The power module 2 includes an assembled structure 1 of a modular water channel, a first heating device 91, and at least one second heating device 92. It should be noted that the power module 2 further includes a top PCB 9, and has a bottom surface 90, and the bottom surface 90 is spatially relative to the assembled structure 1 of the modular water channel. The first heating device 91 and at least one second heating device 92 with heat dissipation requirements in the power module 1 are, for example, arranged on the bottom surface 90 of the top PCB 9, and are respectively thermally coupled to the assembled structure 1 of the modular water channel. In this embodiment, the first heating device 91 is, for example, a magnetic component, and at least one second heating device 92 is, for example, a power device, and the power device is more specifically a surface-mounted power device, surface-mounted to a side PCB 921. Of course, the present invention is not limited thereto. It is worth noting that in this embodiment, the assembled structure 1 of the modular water channel includes a front-end component 10, a first side straight flow channel component 30, a second side straight flow channel component 40, and a bending component 20. Among them, the front-end component 10 includes an inflow port 11, an outflow port 12, and a connection side 13. The inflow port 11 and the outflow port 12 are, for example, respectively arranged on the opposite left and right sides of the connection side 13. The bending component 20 has a first communication end 21 and a second communication end 22 opposite to each other, and are, for example, respectively arranged on the opposite left and right sides of the communication side 23. In this embodiment, the first side straight flow channel component 30 extends along a first horizontal direction (for example, parallel to the Y-axis direction), and is connected between the inflow port 11 and the first communication end 21. The second side straight flow channel component 40 extends along a second horizontal direction, and is connected between the outflow port 12 and the second communication end 22. The second horizontal direction may be the same as the first horizontal direction, or there may be a certain angular deviation. The present invention does not limit this. The first side straight flow channel component 30 and the second side straight flow channel component 40 are arranged at intervals to form two opposite inner heat dissipation surfaces 31, 41, and two opposite outer heat dissipation surfaces 32, 42. In this embodiment, after the assembled structure 1 of the modular water channel, the first heating device 91, and at least one second heating device 92 are assembled, the first heating device 91 is arranged between the inner heat dissipation surface 31 of the first side straight flow channel component 30 and the inner heat dissipation surface 41 of the second side straight flow channel component 40, and the two opposite side walls 911, 912 of the first heating device 91 are respectively thermally connected to the two opposite inner heat dissipation surfaces 31, 41. At least one second heating device 92 is adjacent to the first side straight flow channel component 30 and / or the second side straight flow channel component 40, and is correspondingly thermally connected to at least one of the two opposite outer heat dissipation surfaces 32, 42.In addition, the bottom surface 90 of the top PCB 9 abuts against the top of the front-end component 10, the first side linear flow channel component 30, the second side linear flow channel component 40, and the bending component 20, and the first side linear flow channel component 30 and / or the second side linear flow channel component 40 are respectively located between the first heating device 91 and at least one second heating device 92. Since the first heating device 91 and at least one second heating device 92 are disposed on the bottom surface 90, when the assembled structure 1 of the modular water channel dissipates heat in combination with the first heating device 91 and at least one second heating device 92, the assembled structure 1 of the modular water channel also provides a supporting function. Of course, the present invention is not limited thereto. It should be noted that the assembled structure 1 of the modular water channel includes the front-end component 10, the first side linear flow channel component 30, the second side linear flow channel component 40, and the bending component 20, which are assembled by splicing. By splitting the U-shaped water channel into the first side linear flow channel component 30 and the second side linear flow channel component 40 on both sides and the bending component 20 and then combining the front-end component 10, the optimized heat dissipation efficiency of the power module 2 can be flexibly achieved corresponding to the sizes and configurations of the first heating device 91 and at least one second heating device 92.

[0044] In this embodiment, the first side linear flow channel component 30 and the second side linear flow channel component 40, for example but not limited to, have the same structure and can be used interchangeably. In this embodiment, the first side linear flow channel component 30 has a first front end 301 and a first rear end 302 that are opposite to each other. The first front end 301 is connected to the inlet port 11, and the first rear end 302 is connected to the first communication end 21. Similarly, the second side linear flow channel component 40 has a second front end 401 and a second rear end 402 that are opposite to each other. The second front end 401 is connected to the outlet port 12, and the second rear end 402 is connected to the second communication end 22. In this embodiment, the first side linear flow channel component 30 includes a first side flow channel plate 33 and a first side cover plate 34. The first side flow channel plate 33 has a first groove 35 extending along a first horizontal direction (for example, parallel to the Y-axis direction). The first side cover plate 34 is connected to the first side flow channel plate 33 and covers the first groove 35 to form a first flat inner cavity 300, which communicates with the first front end 301 and the first rear end 302. Similarly, the second side linear flow channel component 40 includes a second side flow channel plate 43 and a second side cover plate 44. The second side flow channel plate 43 has a second groove 45 extending along a second horizontal direction. The second side cover plate 44 is connected to the second side flow channel plate 43 and covers the second groove 45 to form a second flat inner cavity 400, which communicates with the second front end 401 and the second rear end 402. In this embodiment, the first side flow channel plate 33 and the first side cover plate 34, and the second side flow channel plate 43 and the second side cover plate 44 can be fixedly connected by friction welding, laser welding, brazing, diffusion welding, or sealant.

[0045] It should be noted that in this embodiment, the first side linear flow channel component 30 and the second side linear flow channel component 40 are formed into flat inner cavities 300 and 400 by profile parts, stamping parts or die-casting parts. The length and width of the cavities are not restricted by the forming process and can be adjusted according to actual application requirements. Of course, each of the first side linear flow channel component 30 and the second side linear flow channel component 40 can be assembled by a side flow channel plate with grooves and a side cover plate. The side flow channel plate and the side cover plate are assembled by means of friction welding, laser welding, brazing, diffusion welding, electron beam welding or fixing connection with sealant, which is more conducive to reducing the thickness of the components.

[0046] In addition, in this embodiment, the bending component 20 and the front-end component 10 are made of die-casting parts, and the structural strength is greater than or equal to that of the first side linear flow channel component 30 and the second side linear flow channel component 40, which helps to provide sufficient structural support. Furthermore, the first side linear flow channel component 30 and the second side linear flow channel component 40 are respectively fixed and connected to the bending component 20 and / or the front-end component 10 by friction welding, laser welding, brazing, diffusion welding, electron beam welding or sealant to achieve modular splicing.

[0047] When the assembled structure 1 of the modular water channel is applied to the power module 2, the inner heat dissipation surfaces 31 of the first side linear flow channel components 30 and the inner heat dissipation surfaces 42 of the second side linear flow channel components 40 on both sides can be thermally coupled to the two opposite side walls 911 and 912 of the first heating device 91 of, for example, a magnetic component. The outer heat dissipation surfaces 32 of the first side linear flow channel components 30 and the outer heat dissipation surfaces 42 of the second side linear flow channel components 40 on both opposite sides can be respectively thermally coupled to the second heating device 92 such as a surface-mounted power device. In this embodiment, the bending component 20 also provides another outer heat dissipation surface 24 for application, opposite to the communication end 23, and is thermally coupled to another heating device 93. In other embodiments, according to different size requirements of the first heating device 91, the assembled structure 1 of the modular water channel can adjust the interval distance between the first side linear flow channel component 30 and the second side linear flow channel component 40 by adjusting the lengths of the first side linear flow channel component 30 and the second side linear flow channel component 40, or by replacing the bending component 20 and the front-end component 10 to meet different size requirements of the first heating device 91. Of course, the adjustment of the assembled structure 1 of the modular water channel can also be adjusted according to actual application requirements. Thus, the modular disassembly and connection of the first side linear flow channel component 30, the second side linear flow channel component 40, the bending component 20 and the front-end component 10 can be flexibly adjusted according to the quantity, size and arrangement of the heating devices 91, 92 and 93, effectively reducing the development cost and time of the heat dissipation water channel module for developing the applicable power module 2. Furthermore, since the structures of the front-end component 10, the first side linear flow channel component 30, the second side linear flow channel component 40 and the bending component 20 are simplified in design, they can be manufactured by multiple forming processes and have a low cost.

[0048] In this embodiment, the assembly structure 1 of the modular water channel further includes a bottom plate 50, which is disposed below the front-end component 10, the first side straight flow channel component 30, the second side straight flow channel component 40, and the bending component 20 to form an accommodation space 100 for accommodating the first heating device 91. In addition to being thermally connected to the inner heat dissipation surface 31 of the first side straight flow channel component 30 and the inner heat dissipation surface 42 of the second side straight flow channel component 40, the first heating device 91 can also be directly or indirectly thermally connected to the front-end component 10, the bending component 20, and the bottom plate 50.

The inflow pipe 15 is communicated with the inflow port 11, and the outflow pipe 16 is communicated with the outflow port 12. Wherein, the coolant (not shown in the figure) enters from the inflow pipe 15, flows through the inflow port 11, the first side linear flow channel component 30, the first communication end 21 and the second communication end 22 of the bending component 20, the second side linear flow channel component 40 and the outflow port 12, and then is discharged from the outflow pipe 16. In this embodiment, the front-end component 10 further includes a clamping portion 17, which is disposed between the connection side 13 and the inflow pipe 15 and the outflow pipe 16. Wherein, the clamping portion 17 is clamped with the side wall 81 of the housing 8, and the first side linear flow channel component 30, the second side linear flow channel component 40 and the bending component 20 are accommodated in the housing 8, and the inflow pipe 15 and the outflow pipe 16 extend outwards.

In this embodiment, the power supply module 2 further includes an outer cover 82, which is fixed on the housing 8 and covers the assembled structure 1 of the modular water channel, the first heat generating device 91 and at least one second heat generating device 92. In some embodiments, the outer cover 82 and the housing 8 are fixedly connected by bolts, for example. In one embodiment, the power supply module 2 further includes a heat dissipation glue (not shown in the figure), which is filled in the assembled structure 1 of the modular water channel and / or the housing 8. The present invention is not limited thereto.

In some embodiments, the clamping portion 17 of the front-end component 10 is not limited to the trapezoidal shape and the integral circumferential groove or rib, and can be hermetically fitted with the external housing 8.

Of course, the present invention is not limited thereto.

[0050] It should be emphasized that the assembled structure 1 of the modular water channel of the present invention can realize the heat dissipation, installation and fixing, and sealing design of the overall water channel module by simply disassembling and connecting the front-end component 10, the first side linear flow channel component 30, the second side linear flow channel component 40 and the bending component 20, without affecting the splicing of other inflow pipes 15, outflow pipes 16, bottom plates 50 and top covers 82.

Figure 10 and Figure 11 Schematically shows an exploded view of the assembled structure of the modular water channel in the second embodiment of the present invention. Figure 12 Schematically shows a horizontal sectional view of the power supply module in the second embodiment of the present invention.

[0052] Figure 13 Schematically shows a vertical sectional view of the power supply module in the second embodiment of the present invention. In this embodiment, the assembled structure 1a of the power supply module 2a and the modular water channel is similar to the assembled structure 1 of the power supply module 2 and the modular water channel shown in Figures 1 to 7 , and the same component numbers represent the same components, structures and functions, which will not be repeated here. In this embodiment, the power supply module 2a includes the assembled structure 1a of the modular water channel, a first heat generating device 91, and a plurality of second heat generating devices 92a. The first heat generating device 91 is, for example, a magnetic component, and the plurality of second heat generating devices 92a are, for example, through-hole heat generating devices, specifically, through-hole power devices, which are arranged on the bottom surface 90 of the top PCB 9 and are respectively thermally coupled to the first side linear flow channel component 30 and the second side linear flow channel component 40 of the assembled structure 1a of the modular water channel. In this embodiment, after the assembled structure 1a of the modular water channel, the first heat generating device 91, and the plurality of second heat generating devices 92a are assembled, the first heat generating device 91 is disposed between the inner heat dissipation surface 31 of the first side linear flow channel component 30 and the inner heat dissipation surface 41 of the second side linear flow channel component 40, and the two opposite side walls 911, 912 of the first heat generating device 91 are respectively thermally connected to the two opposite inner heat dissipation surfaces 31, 41. In addition, the plurality of second heat generating devices 92a are respectively adjacent to the first side linear flow channel component 30 and the second side linear flow channel component 40, and are correspondingly thermally connected to the two opposite outer heat dissipation surfaces 32, 42.

[0053] In this embodiment, the first side linear flow channel component 30 and the second side linear flow channel component 40 have, for example but not limited to, the same structure and can be used interchangeably. The first side linear flow channel component 30 includes a first side flow channel plate 33 and a first side cover plate 34. The first side flow channel plate 33 has a first groove 25 extending along the first horizontal direction (i.e., parallel to the Y-axis direction). The first side cover plate 34 is connected to the first side flow channel plate 33 and covers the first groove 35, communicating with the first front end 301 and the first rear end 302. Similarly, the second side linear flow channel component 40 includes a second side flow channel plate 43 and a second side cover plate 44. The second side flow channel plate 43 has a second groove 45 extending along the second horizontal direction. The second side cover plate 44 is connected to the second side flow channel plate 43 and covers the second groove 45, communicating with the second front end 401 and the second rear end 402. It should be noted that the outer heat dissipation surface 32 formed by the first side cover plate 34 of the first side linear flow channel component 30 corresponds to a plurality of second heating devices 92a, while the outer heat dissipation surface 42 formed by the second side cover plate 44 of the second side linear flow channel component 40 corresponds to a plurality of second heating devices 92a. Since the plurality of second heating devices 92a are composed of through-hole power devices, they can generally form a thermal connection with the heat dissipation device through a bolt fixing method. In some embodiments, to facilitate the thermal connection between the plurality of second heating devices 92a and the first side linear flow channel component 30, the first side cover plate 34 further includes a boss 36, which protrudes from the outer surface of the first side cover plate 34 to increase the thickness. In terms of space, it is opposite to the plurality of second heating devices 92a, so as to facilitate the plurality of second heating devices 92a to be fixed to the outer heat dissipation surface 32 through a bolt fixing method and form a thermal connection. Similarly, to facilitate the thermal connection between the plurality of second heating devices 92a and the second side linear flow channel component 40, the second side cover plate 44 further includes a boss 46, which protrudes from the outer surface of the second side cover plate 44 to increase the thickness. In terms of space, it is opposite to the plurality of second heating devices 92a, so as to facilitate the plurality of second heating devices 92a to be fixed to the outer heat dissipation surface 42 through a bolt fixing method and form a thermal connection. It can be understood that in some embodiments, due to the diversity of the side linear flow channels, the first side cover plate 34 and / or the second side cover plate 44 may not be provided with bosses 36 and 46. For example, fixing posts, screw holes, etc. can be provided to make the second heating devices 92a adhere to and be fixed to the first side cover plate 34 and / or the second side cover plate 44. In other embodiments, the first side linear flow channel component 30 and the second side linear flow channel component 40 are composed of profile parts, stamping parts or die-cast parts, and the length and width of the cavity are not limited by the forming process, and the dimensions can be adjusted according to actual application requirements.In addition, the first side flow channel plate 33 and the first side cover plate 34 that constitute the first side linear flow channel component 30, and the second side flow channel plate 43 and the second side cover plate 44 that constitute the second side linear flow channel component 40 can be assembled by friction welding, laser welding, brazing, diffusion welding, electron beam welding or fixing connection with sealant, which is more conducive to reducing the thickness of the components, and the types of the first side cover plate 34 and the second side flow channel plate 43 can also be changed according to actual application requirements to achieve diversified applications. Of course, the present invention is not limited thereto and will not be elaborated further.

[0054] In summary, the present invention provides an assembly structure of a modular water channel and a power module applicable thereto. By splitting the independent U-shaped water channel heat dissipation module into linear flow channel components on both sides, bending components, and then combining with the front-end components, each component is modularly spliced, and the optimized heat dissipation efficiency of the power module can be flexibly achieved. Among them, the linear flow channel components on both sides can form a flat inner cavity through profile parts, stamping parts, or die-casting parts. The length and width of the cavity are not limited by the forming process and can be adjusted according to actual application requirements. Of course, each linear flow channel component can also be assembled by a side flow channel plate with grooves and a side cover plate. The side flow channel plate and the side cover plate are assembled by friction welding, laser welding, brazing, diffusion welding, electron beam welding, or fixing connection with sealant, which is more conducive to reducing the thickness of the components. Furthermore, the bending component and the front-end component are composed of die-casting parts, which can provide sufficient structural support and can be modularly spliced with the linear flow channel components on both sides by friction welding, laser welding, brazing, diffusion welding, electron beam welding, or fixing connection with sealant. On the other hand, when the assembly structure of the modular water channel is applied to the power module, the opposite inner heat dissipation surfaces of the linear flow channel components on both sides can correspond to the two opposite sides of the thermally coupled magnetic components, and the outer heat dissipation surfaces of the linear flow channel components on both sides can be thermally coupled to through-hole power devices or a surface-mounted power device respectively. In addition, the bending component also provides another outer heat dissipation surface for application. Thus, the modular disassembly and connection of the linear flow channel components on both sides and the bending component combined with the front-end component can be flexibly adjusted according to the number, size, and arrangement of the heat-generating devices, effectively reducing the development cost and time of the heat dissipation water channel module for developing a suitable power module. Since the structures of the front-end component, the linear flow channel components on both sides, and the bending component are simplified in design, they can be manufactured through multiple forming processes and have a low cost. In addition, the assembly structure of the modular water channel can be hermetically fitted with the external casing through the engaging part of the front-end component. The engaging part is not limited to being formed by a trapezoidal shape and a whole-circle groove or rib. The front-end component and the bending component can also be fixed to the casing by screws respectively, and then heat dissipation glue is filled to further enhance the heat dissipation efficiency. The present invention can realize the heat dissipation, installation fixation, and sealing design of the overall water channel module by simply disassembling and connecting the front-end component, the linear flow channel components on both sides, and the bending component, without affecting the splicing of other inflow pipes, outflow pipes, bottom plates, and top covers. For heat dissipation scenarios that need to adapt to different lengths and widths, the assembly structure of the modular water channel of the present invention only needs to change the dimensions of some structural parts to achieve low-cost adaptation and has greater versatility.
