[0022] Current dual-motor controllers have a complex structure, with each power module corresponding to a heat sink. Assembly requires sequentially installing each component into the housing, a complex, time-consuming, and labor-intensive process that impacts production efficiency. Therefore, this application provides a dual-motor controller where the modules can be integrated on another production line before being installed in the housing, thereby improving production efficiency and reducing the size of the dual-motor controller.
[0023] Firstly, this application provides a dual-motor controller, as referenced Figure 1 The dual-motor controller includes a housing 1 and an inverter brick 2. The housing 1 defines an accommodating space, and the inverter brick 2 is located within the accommodating space.
[0024] refer to Figure 2 The inverter brick 2 includes a copper busbar assembly 21, a liquid cooling plate 22, a first power device 23, a second power device 24, a filter assembly 25, and a bus capacitor 26. The liquid cooling plate 22 is connected to the housing 1. The copper busbar assembly 21 is connected to the liquid cooling plate 22 and electrically connected to the input terminal of the filter assembly 25. Along the thickness direction X of the liquid cooling plate 22, the first power device 23 and the second power device 24 are installed on one side of the liquid cooling plate 22, and the bus capacitor 26 and the filter assembly 25 are installed on the other side of the liquid cooling plate 22. The output terminal of the filter assembly 25 is electrically connected to the input terminal of the bus capacitor 26, and the output terminal of the bus capacitor 26 is electrically connected to the input terminals of the first power device 23 and the second power device 24.
[0025] The first power device 23 and the second power device 24 are laid flat on one side of the liquid cooling plate 22, such as above the liquid cooling plate 22. The bus capacitor 26 and the filter assembly 25 are laid flat on the other side of the liquid cooling plate 22, such as below the liquid cooling plate 22. A first heat dissipation cavity 221 and a second heat dissipation cavity 222 are provided on one side of the liquid cooling plate 22. The first heat dissipation cavity 221 and the second heat dissipation cavity 222 are connected to the cooling channels in the liquid cooling plate 22. The first power device 23 and the second power device 24 are respectively arranged opposite to the first heat dissipation cavity 221 and the second heat dissipation cavity 222. The heat-conducting column of the first power device 23 extends into the first heat dissipation cavity 221, and the heat-conducting column of the second power device 24 extends into the second heat dissipation cavity 222, so that the liquid cooling plate 22 can dissipate heat from the first power device 23 and the second power device 24 simultaneously.
[0026] In this application, the positive and negative terminals of the input end of the copper busbar assembly 21 are connected to the positive and negative terminals of the controller wiring harness of the battery pack, respectively. The positive and negative terminals of the output end of the copper busbar assembly 21 are connected to the positive and negative terminals of the input end of the filter assembly 25, respectively. The positive and negative terminals of the output end of the filter assembly 25 are connected to the positive and negative terminals of the input end of the bus capacitor 26, respectively.

The three-phase output terminals of the first power device 23 are connected to the three-phase terminals of the corresponding first motor through the first three-phase adapter copper busbar 60, respectively. At the same time, the positive and negative terminals of the output end of the bus capacitor 26 are connected to the positive and negative terminals of the second power device 24 through the capacitor adapter copper busbar 50, respectively. The three-phase output terminals of the second power device 24 are connected to the three-phase terminals of the corresponding second motor through the second three-phase adapter copper busbar 70, respectively. That is, through the above circuit connection, the inverter process is realized, outputting three-phase AC power to drive the three-phase motor to run. The dual-motor controller also includes a control and drive integrated board 27. The pins of the first power device 23 and the pins of the second power device 24 are respectively connected to the control and drive integrated board 27 to realize drive control.
[0027] In this application, the inverter process is implemented using only one liquid cooling plate 22, one copper busbar assembly 21, one filter assembly 25, and one bus capacitor 26, which simplifies the structure of the motor controller. Furthermore, in this application, the first power device 23, the second power device 24, the copper busbar assembly 21, the filter assembly 25, and the bus capacitor 26 are all integrated on the liquid cooling plate 22, which reduces the overall volume of the inverter brick 2 and increases the power density of the inverter brick 2. The integrated inverter brick 2 is then installed on the housing 1. The entire assembly process of the inverter brick 2 can be completed on other production lines and then transported to the controller production line for assembly with the housing 1, thereby improving the assembly efficiency of the spare controller production line. In addition, the dual-motor controller can be disassembled and maintained as a whole during maintenance, reducing maintenance costs.

Specifically, one end of the copper busbar assembly 21 is connected to the battery pack, and the other end is connected to the filter assembly 25. Since the copper busbar assembly 21 receives direct current, it will generate significant heat. This application addresses this by providing the first thermal pad 3, which abuts against the copper busbar assembly 21 and the lower housing 12 on both sides along its thickness direction, thereby dissipating the heat generated by the copper busbar assembly 21 to the lower housing 12 and achieving heat dissipation for the copper busbar assembly 21.
[0029] During the assembly of the dual-motor controller, the modular inverter brick 2 is placed on the lower housing 12, the liquid cooling plate 22 is fixedly connected to the lower housing 12, and then the upper housing 11 is fixed to the lower housing 12, thereby realizing the assembly of the dual-motor controller, simplifying the assembly process and improving production efficiency. For example, the first thermal pad 3 can be made of silicone with high dielectric strength and high thermal conductivity.

The second liquid inlet 223 and the second liquid outlet 224 are connected to the cooling channels and the first heat dissipation cavity 221 and the second heat dissipation cavity 222 in the liquid cooling plate 22. The cooling fluid enters from the first liquid inlet 121, passes through the second liquid inlet 223, the first heat dissipation cavity 221, the second heat dissipation cavity 222 and the second liquid outlet 224, and then flows out through the first liquid outlet 122, thereby achieving heat dissipation for the first power device 23 and the second power device 24.

The two sides of the second thermal pad 9 abut against the first copper busbar 8 and the liquid cooling plate 22 respectively. The second thermal pad 9 can conduct the heat generated by the first copper busbar 8 to the liquid cooling plate 22, thereby achieving heat dissipation of the filter assembly 25. For example, the second thermal pad 9 can be made of silicone with high dielectric strength and high thermal conductivity.

The third thermal pad 20 can conduct the heat generated by the second copper busbar 10 to the liquid cooling plate 22, thereby achieving heat dissipation of the bus capacitor 26. For example, the third thermal pad 20 can be made of silicone with high dielectric strength and high thermal conductivity.
[0036] It should be understood that the second copper busbar 10 includes a second positive copper busbar and a second negative copper busbar. The second positive copper busbar is connected to the positive terminal of the output terminal of the filter component 25, and the second negative copper busbar is connected to the negative terminal of the output terminal of the filter component 25.
[0037] In one specific embodiment, reference Figure 2 A fourth thermal pad 80 is provided at the output end of the bus capacitor 26. The two sides of the fourth thermal pad 80 abut against the output end of the bus capacitor 26 and the liquid cooling plate 22, respectively, to conduct the heat generated at the output end of the bus capacitor 26 to the liquid cooling plate 22, thereby achieving heat dissipation of the bus capacitor 26. For example, the fourth thermal pad 80 can be made of silicone with high dielectric strength and high thermal conductivity.
