在该实施方式中，对于该功率模块5的具体形式，虽然可以是本领域人员所知的多种。但是，考虑到本申请的目的是为了节约电机控制器的整体设计体积，那么在本申请的一个示例中，该功率模块5可以是碳化硅模块（SiC模块）。碳化硅模块相较于传统的IGBT，具有更小的体积，能够进一步降低电机控制器的设计体积。另外，为了进一步提高碳化硅模块的散热效率，该碳化硅模块的背面可以设置有多个pin-fin翅片。In this embodiment, the specific form of the power module 5 may be of various types known to those in the art. However, considering that the purpose of this application is to save the overall design volume of the motor controller, in an example of this application, the power module 5 may be a silicon carbide module (SiC module). Compared with traditional IGBTs, silicon carbide modules have a smaller size, which can further reduce the design size of the motor controller. In addition, in order to further improve the heat dissipation efficiency of the silicon carbide module, multiple pin-fin fins can be provided on the back of the silicon carbide module.
在该实施方式中，对于该冷却模块4的具体形式，虽然可以是本领域人员所知的多种形式。例如由多条风管构成的风冷通道和压缩机的组合等。但是考虑到散热效率以及设计体积，在本申请的一个可选示例中，该冷却模块4可以是包括水冷板。具体地，该水冷板的结构可以是如图6所示。在该图6中，该水冷板的顶部可以设置有至少一个水槽6-1和外侧翻边延伸区域6-3。水槽6-1可以用于供碳化硅模块的pin-fin翅片***，从而提高散热效率。外侧翻边延伸区域6-3为金属结构，用于完成水冷板两侧的磁场屏蔽。在一实施方式中，为了保证碳化硅模块和水冷板之间的水密性，该水槽6-1的边缘可以设置有密封圈6-2。对于该水槽6-1的数量，可以是本领域人员所知的多个数值，例如2、3、4个等。在本申请的一个可选示例中，考虑到电机控制器本身的电路需求以及水冷板本身的散热能力，该水槽6-1的数量可以是3个。相应地，功率模块5的数量也可以是3个。In this embodiment, the specific form of the cooling module 4 may be in various forms known to those in the art. For example, a combination of air cooling channels and compressors composed of multiple air ducts. However, considering the heat dissipation efficiency and design volume, in an optional example of this application, the cooling module 4 may include a water-cooling plate. Specifically, the structure of the water-cooling plate may be as shown in Figure 6. In Figure 6, the top of the water-cooling plate may be provided with at least one water groove 6-1 and an outer flange extension area 6-3. The water tank 6-1 can be used to insert the pin-fin fins of the silicon carbide module, thereby improving the heat dissipation efficiency. The outer flange extension area 6-3 is a metal structure and is used to complete the magnetic field shielding on both sides of the water-cooling plate. In one embodiment, in order to ensure the water tightness between the silicon carbide module and the water-cooling plate, a sealing ring 6-2 may be provided on the edge of the water tank 6-1. The number of water tanks 6-1 can be multiple values known to those in the art, such as 2, 3, 4, etc. In an optional example of this application, considering the circuit requirements of the motor controller itself and the heat dissipation capacity of the water-cooling plate itself, the number of the water tanks 6 - 1 may be three. Correspondingly, the number of power modules 5 may also be three.
在该实施方式中，在三相铜排及电路检测组件6中，虽然三相铜排的出线端的方向可以是本领域人员所知的多种。但是，考虑到Boost负极出线9的方向，为了进一步降低电机控制器以及对应的***电路的设计体积，三相铜排的出线端方向可以是与该Boost负极出线9的出线方向相同，例如图2中的方向a。在该出线端的方向为a的情况下，如图7所示，该三相铜排直接伸进电机内，能够以最短的路径完成连接，从而最大程度地降低了整体的设计体积。此外，在该三相铜排的***，也可以设置有对应的屏蔽磁环。In this embodiment, in the three-phase copper bar and circuit detection component 6, the directions of the outlet ends of the three-phase copper bar can be in various directions known to those in the art. However, considering the direction of the Boost negative electrode outlet 9, in order to further reduce the design volume of the motor controller and the corresponding peripheral circuits, the outlet direction of the three-phase copper bar can be the same as the outlet direction of the Boost negative electrode outlet 9, for example, Figure 2 in the direction a. When the direction of the outlet end is a, as shown in Figure 7, the three-phase copper bar extends directly into the motor, and the connection can be completed in the shortest path, thus minimizing the overall design volume. In addition, corresponding shielding magnetic rings can also be provided around the three-phase copper bar.
