Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a motor controller 100 according to the present invention includes a substrate 1 and a driving module 2. Wherein the base plate 1 extends transversely for fixing. And the driving module 2 is an IGBT driving module. The IGBT modules are respectively disposed on the upper and lower sides of the substrate 1 to optimize the structure of the motor controller 100, so that the structure is compact, and the motor controller facilitates modularization and easy assembly and disassembly.

As shown in fig. 2, the substrate 1 has a cooling tank 11 for cooling down the drive module 2. The cooling box 11 may have a rectangular box shape. A partition plate 12 is provided in an inner cavity of the cooling tank 11 to divide the cooling tank 11 into an upper space 13 and a lower space 14, and the upper and

lower spaces

13, 14 communicate with each other. An outlet 15 is provided at the left end of the cooling box 11 for communication with the upper space. Meanwhile, an inlet 16 is provided at the left end of the cooling tank 11 for communication with the lower space, as shown in fig. 3. Thus, the cooling medium (which may be water, for example) enters the lower space 14 through the inlet 16 to dissipate heat mainly from the drive module 2 disposed on the lower side of the cooling box 11. Then, the cooling medium passes through the partition plate 12, enters the upper space 13, and radiates heat mainly to the drive module 2 disposed above the cooling box 11. Finally, the cooling medium flows out through the outlet 15. The arrangement mode enables the heat dissipation to be good and the efficiency to be high.

A communication hole 17 is provided in the partition plate 12 for communicating the upper space 13 and the lower space 14. For example, the communication hole 17 may be configured in plural and evenly distributed between the middle and the right end of the cooling box 11. By this arrangement, a part of the cooling medium is bypassed from the farthest position to the outlet, and the flow path is long, so as to improve the utilization efficiency of the cooling medium. Meanwhile, a part of the cooling medium enters the upper space from the lower space through the communication hole closer to the inlet, so that the part of the cooling medium enters the upper space without absorbing much heat, thereby improving the cooling effect on the drive module 2 at the upper side. When the driving modules 2 on both sides of the cooling box 11 are cooled by the above arrangement, the cooling efficiency of the cooling liquid and the cooling effect on the two driving modules 2 are both considered, which is helpful for prolonging the service life of the motor controller 100. Of course, the communication hole 17 may also be configured as a through hole near the right end as shown in fig. 2 for simplicity. In fig. 2 and 3, the arrow direction indicates the cooling medium flow direction.

The separator 12 is configured as a corrugated plate, and the corrugations of the separator 12 extend in the front-to-rear direction. That is, the direction in which the corrugations of the separator 12 extend is perpendicular to the flow direction of the cooling medium. This arrangement increases the contact area of the cooling medium with the partition 12, thereby transferring heat between the upper space 13 and the lower space 14, and contributing to balance the effect of heat dissipation to the drive modules 2 on both sides of the cooling box 11. In addition, the above arrangement also agitates the flow state of the cooling medium, thereby increasing the heat radiation efficiency.

An inlet adapter is provided at the inlet. Meanwhile, an outlet pipe joint is arranged at the outlet. By providing the inlet pipe joint and the outlet pipe joint, the cooling medium can be introduced and drawn out easily, contributing to the realization of the communication of the cooling box 11 with the outside cooling source and the like. In addition, sealing rings are arranged between the inlet pipe joint and the inlet 16 and between the outlet pipe joint and the outlet 15, so that sealing is realized, and the use safety is ensured.

A support bracket 5 extending in the longitudinal direction is vertically provided at the rear end of the base plate 1. A capacitor 6 is fixed to the rear wall surface of the support frame 5. This arrangement allows the capacitor 6 to be located on the other side of the drive module 2, on the support 5. The arrangement is simple and compact. In addition, by providing the support frame 5 and the capacitor 6 at the rear end of the substrate 1, the structure is modularized, and operations such as mounting and dismounting are facilitated.

The rear wall surface of the support frame 5 is provided with vertically extending mounting plates 51 which are arranged in a left-right opposed manner. A fixing post 52 extending vertically is provided on the outer side of each mounting plate 51. A laterally extending carrier plate 53 is provided at the lower end of the support frame 5. After capacitor 6 is mounted on support frame 5, the lower end of capacitor 6 is received by carrier plate 53, and both ends are connected to fixing post 52 by, for example, screw connection, and a part of capacitor is embedded in mounting plate 51.

Preferably, a notch 54 is provided in the support 5. The gap 54 provides a working space for connection and installation of the components, and reduces the weight of the support frame 5 itself, contributing to weight reduction.

A rib plate 7 is arranged between the support frame 5 and the base plate 1. Preferably, two oppositely distributed rib plates 7 are arranged on the upper surface of the base plate 1. The rib 7 is triangular, and is fixedly connected to the base plate 1 at one side and to the support plate 5 at the other side, and is used for reinforcing the fixed connection between the support plate 5 and the base plate 1. Meanwhile, a rib 7 may be provided on the lower surface of the base plate 1 similarly as described above.

The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily make changes or variations within the technical scope of the present invention, and such changes or variations should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
