Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of inverters, and particularly relates to an inverter shell and an inverter. BACKGROUND

[0002] The electric drive axle is a power assembly of a new energy electric vehicle and is composed of an inverter, a motor and a reducer. The inverter is used for converting direct current of a high-voltage battery of the vehicle into high-voltage alternating current and driving the motor in a mode required by a customer. As a control center of the electric drive axle assembly, the integrated design of the inverter is crucial to the function, quality and efficiency of the electric drive axle assembly.

[0003] The inverter shell is a main fixing carrier of the inverter. In the prior art, the inverter shell is generally a cast part. The upper cover plate and the lower shell are fixed by screwing and sealed by sealing glue. The PCB plate and the support plate are fixed by screwing. The support plate and the lower shell are fixed by screwing. The water-cooling plate and the lower shell are fixed by screwing and sealed by sealing glue. The sealing ring support and the sealing ring are connected with the water-cooling plate by a pressing plate and screws to form a closed water channel and realize the cooling and heat dissipation of the power module.

[0004] The existing inverter mainly has the following defects:

[0005] The wall thickness of the die-cast water channel is relatively thick, which is not conducive to lightweight design and has a low thermal conductivity due to the limitation of the die-casting material, which is not conducive to heat dissipation. The die-casting mold is complex, and the high-temperature and high-pressure forming process has high requirements and high cost. The die-casting process inevitably has defects such as pores and shrinkage holes, which affects the cooling efficiency. The die-casting water channel has a large volume, and the internal structure cannot be formed to be more conducive to flow resistance and heat dissipation. The connection between the die-casting support structure and the shell is limited by the material properties and cannot be welded. The sealing between the die-casting shell and the upper cover must use a sealing ring or wet glue sealing, and screws are used for fixing, which increases the volume of the assembly, the rhythm and complexity of the whole machine assembly process.

[0006] In addition, the existing inverter plastic potting bus capacitor needs a screw fixing structure, and the plastic fixing structure is prone to cracking. The heat dissipation of the bus capacitor is mainly through the adhesion and conduction of the metal heat sink plate on one side to the cooling plate. For high-power working conditions, the heat dissipation efficiency is a great challenge. SUMMARY

[0007] In view of the defects of the prior art described above, the purpose of the present application is to provide an inverter shell and an inverter which are lightweight, easy to manufacture and assemble, and can improve the heat dissipation efficiency.

The actual implementation of each component may be a random change, and the component layout pattern may be more complex.

[0044] The inverter housing and inverter provided by the present application can be directly applied to new energy automobile power drive and power system assembly, for example, applied to electric drive axle. In the electric drive axle application scenario, the inverter is used to convert the high-voltage direct current of the battery into the high-voltage alternating current required by the motor. The technical solutions of the present application will be described in detail in combination with specific embodiments.

[0045] Please refer to Figures 1-5 The embodiment of the present application provides an inverter, which comprises an inverter housing 10, a power module 20, a bus capacitor, a main output copper bar 30, a drive board 40 and a control board 50. The inverter housing 10 serves as the mounting carrier of the power module 20, the bus capacitor, the main output copper bar 30, the drive board 40 and the control board 50. The input copper bar 72 of the bus capacitor is used to connect the battery. The output copper bar 71 of the bus capacitor is connected with the direct current input end of the power module 20. The power module 20 performs direct current / alternating current conversion. The alternating current output end of the power module 20 is connected with the main output copper bar 30. The main output copper bar 30 is used to connect the motor. The drive board 40 and the control board 50 are used to collect the current or voltage signals of each node of the electric drive axle and control the running state of each component.

[0046] Please refer to Figure 1As shown, in a specific embodiment, the inverter housing 10 includes a first mounting plate 11, a second mounting plate 12, two side plates 13, and two end plates 14; the first mounting plate 11 is provided with cooling channels 15 arranged along a first direction; the second mounting plate 12 is parallel to the first direction and is spaced apart from the first mounting plate 11; the two side plates 13 are parallel to the first direction and are connected between the first mounting plate 11 and the second mounting plate 12, and the two side plates 13, together with the first mounting plate 11 and the second mounting plate 12, enclose a receiving cavity 101 parallel to the first direction; the two end plates 14 are respectively installed at both ends of the receiving cavity 101; the first mounting plate 11, a portion of the sidewalls of the cooling channels 15, the two side plates 13, and the second mounting plate 12 are made of an integrally formed extruded aluminum profile.

[0047] This invention integrates the cooling channel 15 onto the inverter housing 10. The main structure of the inverter housing 10 has a consistent cross-sectional shape at all locations, allowing for the direct use of extruded aluminum profiles as blanks. The various detailed features are then cut out through machining. Compared to traditional die-cast housings, this invention has a simpler molding process and lower manufacturing costs. Furthermore, the thermal conductivity of extruded aluminum profiles is superior to that of traditional die-cast housings. In addition, since the housing is made of extruded aluminum material, it can be easily welded to other structural components, avoiding redundant connections and sealing structures.

[0048] It should be understood that, in addition to the above embodiments, the inverter housing 10 of the present invention can also freely choose the integration method according to actual design needs. For example, in some other embodiments, only the cooling channel 15 and the first mounting plate 11 can be integrated into a single structure, that is, the cooling channel 15 and the first mounting plate 11 are made of extruded aluminum profiles, while the side plate 13 and the second mounting plate 12 are made of separate extruded aluminum profiles, and then the two are welded together in real time; or, for example, the first mounting plate 11, the cooling channel 15 and the side plate 13 can be integrated into a single structure, all three of which are made of a single extruded aluminum profile, and then the extruded aluminum profile is welded to the second mounting plate 12. Of course, under the guidance of these embodiments, for example, integrating one side plate 13 with the first mounting plate 11, integrating another side plate 13 with the second mounting plate 12, or dividing the side plate 13 into two parts and integrating them into the first mounting plate 11 and the second mounting plate 12 respectively, these simple modifications should all fall within the scope of protection claimed by the present invention.

[0049] Please see Figure 1As shown in the optional embodiment of the present application, the cooling flow channel 15 comprises a cooling groove 151 and a cover plate 152, at least the first mounting plate 11 and the cooling groove 151 are made of an integrally formed extruded aluminum profile, the opening of the cooling groove 151 is arranged at the side opposite to the accommodating cavity 101, and the cover plate 152 is installed at the opening of the cooling groove 151 to enclose the cooling flow channel 15. The two ends of the cooling groove 151 are respectively protruded from the two ends of the accommodating cavity 101 to form a first protruding portion and a second protruding portion, the first protruding portion and the second protruding portion are respectively provided with an inlet 153 and an outlet 154, and the two ends of the cooling groove 151 are respectively provided with a sealing member 155. In the specific embodiment, the cooling groove 151, the cover plate 152 and the sealing member 155 can be fixed by welding, and the heat-conducting medium in the cooling flow channel 15 can be cooling water or cooling oil.

[0050] It should be understood that the present embodiment arranges the inlet 153 and the outlet 154 below the cooling flow channel 15, which can be compatible with the water channel design of the existing electric drive axle, and can facilitate the compression sealing of the water inlet pipe and the water outlet pipe.

[0051] As shown in Figure 2 , 5 The power module 20 is installed at the side of the cooling flow channel 15 opposite to the accommodating cavity 101. It should be understood that the power module 20 is the main heat-generating element of the inverter, and the present application closely installs the power module 20 against the cooling flow channel 15 to effectively ensure the heat dissipation efficiency of the inverter. In the further preferred embodiment, in order to make the power module 20 and the cooling flow channel 15 have better heat conduction efficiency, a heat-conducting medium such as heat-conducting silica gel can be arranged between the power module 20 and the cooling flow channel 15.

[0052] As shown in Figure 3 , 4As shown, in an optional embodiment of the present invention, the end plate 14 is a plastic plate, which is installed between the inner walls of the end of the receiving cavity 101 by an interference fit; the cooling channel 15 is located in the middle region of the width direction of the first mounting plate 11, where the width direction of the first mounting plate 11 refers to the direction perpendicular to the first direction and parallel to the surface of the first mounting plate 11; a hollow portion 111 is provided on one side of the first mounting plate 11 of the cooling channel 15. The bus capacitor (not shown) is housed in the receiving cavity 101, which is filled with structural adhesive. It should be understood that the present invention integrates a bus capacitor housing, and the bus capacitor is assembled into a capacitor core assembly by capacitor core, copper busbar, and insulating paper, and the capacitor core assembly is connected to the housing by a vacuum potting process. In a specific embodiment, after the capacitor core assembly is installed in place, the two end plates 14 are installed at both ends of the receiving cavity 101. Then, the receiving cavity 101 is filled with adhesive through the hollow part 111. After the adhesive cures, the bus capacitor and the inverter housing form a whole. In this embodiment, the plastic end plates 14 can be tightly connected with the structural adhesive, thereby eliminating the need for connection processes for other structures of the end plate 14 housing, simplifying the assembly process, reducing material costs, and making the device lighter.

[0053] Please see Figure 5 As shown, the output copper busbar 71 of the bus capacitor passes through the hollow part 111 and is connected to the input terminal of the power module 20; the main output copper busbar 30 is mounted on the first mounting plate 11 and is electrically connected to the output terminal of the power module 20; the main output copper busbar 30 and the hollow part 111 are respectively located on both sides of the width direction of the cooling channel 15, and the upstream and downstream components of the power module 20 are more compactly arranged, which is conducive to realizing the miniaturization design of the inverter.

[0054] Please see Figure 4 As shown, in an optional embodiment of the invention, at least one of the end plates 14 is provided with a via through which the input copper busbar 72 of the bus capacitor extends to the outside of the receiving cavity 101. In the illustrated embodiment, the input copper busbar 72 is introduced from one of the end plates 14. It should be understood that in some other embodiments, the input copper busbar 72 may be introduced from both end plates 14, for example.

[0055] Please see Figures 2-5As shown, the drive board 40 is mounted on the side of the power module 20 opposite to the first mounting plate 11, and the power module 20 is electrically connected with the drive board 40. A shielding support plate 41 made of metal is arranged between the drive board 40 and the inverter housing 10, the edge of the shielding support plate 41 is connected with the first mounting plate 11, and the drive board 40 is mounted on the side of the shielding support plate 41 opposite to the inverter housing 10. Preferably, an insulating layer is arranged on the surface of the shielding support plate 41. The control board 50 is mounted on the side of the second mounting plate 12 opposite to the accommodating cavity 101, and the control board 50 is electrically connected with the drive board 40 through the wire 60.

[0056] It should be understood that the present application splits one PCB board of a conventional inverter into a drive board 40 and a control board 50, which can separate strong and weak electricity, prevent signal interference, and make the inverter structure more compact and facilitate miniaturization design.

[0057] Please refer to Figures 1-5 As shown, in specific embodiments, the inverter housing 10 further comprises a mounting foot 16 for facilitating connection of the inverter with an electric drive axle housing, and the mounting foot 16 is mounted on the second mounting plate 12 or the side plate 13 or the connection between the mounting plate and the side plate 13.

[0058] In summary, the inverter housing 10 of the present application has low raw material cost, small material volume, low mold cost, and simple forming process, which can greatly reduce the raw material cost of the inverter; the water-cooled plate and the sealing ring part are combined in one, which reduces the complexity of the inverter assembly process and the production process cost of the inverter; the parts are fixedly connected and the water channel sealing function is realized by welding, which can save the assembly process of glue coating / sealing ring assembly and screwing, reduces the complexity of the inverter assembly process, and reduces the production rhythm; the wall thickness of the extruded aluminum profile is thinner, which makes the overall volume and weight of the inverter smaller, greatly improves the space utilization of the inverter on the whole vehicle; the aluminum housing provides the feasibility of laser welding, which enables the water channel to be connected with the upper cover and the end cover by welding, further reduces the boundary of the inverter, and improves the space utilization of the whole vehicle; the forming material of the extruded aluminum profile has dense material organization and few defects such as pores, which reduces the risk of water channel leakage and improves the corrosion resistance of the water channel, which is beneficial to improve the product quality of the inverter; the aluminum housing has high thermal conductivity and good heat conduction efficiency, which is beneficial to improve the heat dissipation efficiency of the inverter; the wall thickness of the extruded aluminum profile can reach 0.5mm-1.0mm, which is thinner, and under the same water channel volume, the heat dissipation efficiency is improved, and the overall power density of the inverter product is greatly improved; the present application has simple forming and flexible process, which is beneficial to the subsequent modification and upgrading of the inverter.
