[0002] In the electronic control and power supply system, power devices are core components, and their stable and reliable operation is crucial. To ensure that these high-power components continue to work efficiently, an effective heat dissipation strategy must be implemented. The heat sink design scheme commonly used in the market is mainly based on the series water channel 1 layout (see Figure 1 ), this layout limits the flow path of the coolant and only provides a single channel from the inlet to the outlet. This design has significant disadvantages: first, when the coolant flows in a single path, the flow resistance increases significantly, reducing the heat dissipation efficiency; second, due to the fixed path, the cooling effect received by the power devices in different positions is uneven, resulting in a large temperature difference between the devices in the entire heat dissipation path, further affecting the overall heat dissipation performance and stability of the system. In addition, the wall thickness of the local position of the electronic control housing is relatively thick (see Figure 2 The die-casting process is prone to the risk of quality defects such as shrinkage holes.

[0040] like Figures 7 to 9 As shown, in an embodiment of the present application, an electric control cooling water channel structure includes a water inlet 6, a water outlet 5, a power supply cooling water channel and an electric control cooling water channel; wherein the water inlet 6 is arranged on the outer surface of the electric control housing 2 for introducing coolant. The water outlet 5 is arranged on the outer surface of the electric control housing 2 for discharging coolant. The power supply cooling water channel has a plurality of first water channels arranged in parallel, and the power supply cooling water channel is connected to the water inlet 6. The electric control cooling water channel has a plurality of second water channels arranged in parallel, and the electric control cooling water channel is respectively connected to the power supply cooling water channel and the water outlet 5.

[0041] like Figure 7 As shown, in the embodiment of the present application, the electrically controlled cooling water channel structure realizes independent and efficient cooling of the power module 3 and the electrically controlled power module 7 through a plurality of first water channels and second water channels arranged in parallel. This design can significantly improve the cooling efficiency and reduce local overheating.

[0042] In the embodiment of the present application, the water inlet 6 and the water outlet 5 are both arranged on the outer side of the electronic control housing 2, so that the entire cooling system has a compact structure and can be easily integrated into an all-in-one electric drive controller or other equipment.

[0043] like Figures 3 to 6 As shown, in a possible embodiment, the water inlet nozzle 6 and the water outlet nozzle 5 are pressed into the electronic control housing 2 by gluing and interference fit.

[0044] like Figures 3 to 6 As shown, in an embodiment of the present application, an electric control housing includes an electric control housing body, a water inlet nozzle 6, a water outlet nozzle 5, a power supply cooling water channel cover plate 4 and an electric control cooling water channel cover plate 10. Among them, a partition is provided in the electric control housing body to separate the electric control housing 2 into two layers, an upper layer and an lower layer. The water inlet nozzle 6 is arranged on the outer surface of the electric control housing 2 for introducing coolant. The water outlet nozzle 5 is arranged on the outer surface of the electric control housing 2 for discharging coolant. The power supply cooling water channel cover plate 4 is welded to the top surface of the partition to form a power supply cooling water channel, which is connected to the water inlet nozzle 6, and a first dividing rib 8 is provided in the power supply cooling water channel, which divides the power supply cooling water channel into a plurality of parallel first water channels. The electrically controlled cooling water channel cover plate 10 is welded to the bottom surface of the partition to form an electrically controlled cooling water channel, which is respectively connected to the power cooling water channel and the water outlet 5, and a second dividing rib 9 is provided in the electrically controlled cooling water channel, which divides the electrically controlled cooling water channel into a plurality of parallel second water channels.

[0045] In the embodiment of the present application, the electronic control housing 2 is divided into two layers, upper and lower, by a partition, which are used to install the power module 3 and the electronic control power module 7, respectively, to achieve a clear division of functional areas and improve the overall performance and maintainability of the equipment. The power cooling water channel and the electronic control cooling water channel are respectively divided into multiple parallel water channels by the first dividing rib 8 and the second dividing rib 9, and the flow of each branch is uniform, ensuring that the temperature of each branch is consistent, reducing the internal flow resistance, and improving the heat dissipation efficiency.

[0046] like Figure 8 As shown, in a possible embodiment, a power supply cooling channel groove 2a is provided on the top surface of the partition, and the power supply cooling water channel cover plate 4 is sealed and matched with the power supply cooling channel groove 2a (by welding) to form a power supply cooling water channel.

Since the heat dissipation surface of the power module 3 needs to be a plane, the design of the slope surface 2b and the inverted "J" shape structure of the power supply cooling water channel cover plate 4 can ensure that the water flow cross-sectional area does not change suddenly, while reducing the wall thickness of the partition (see Figure 8 D area) to ensure uniform wall thickness, reduce the length of the heat transfer path and improve the cooling effect.

The electric control cooling water channel cover plate 10 is hermetically fitted with the electric control cooling flow channel groove 2c to form an electric control cooling water channel. The cross-section of the electric control cooling water channel cover plate 10 is in a "ji" shape. Designing the cross-section of the electric control cooling water channel cover plate 10 in a "ji" shape can increase the strength of the electric control cooling water channel cover plate 10, while reducing the water passing cross-section to increase the flow rate and enhance the heat dissipation effect.

The electric control housing adopts the electric control housing 2 in the embodiment of the present application.

[0051] As Figure 5 and Figure 6 shown, in the embodiment of the present application, the electric control power module 7 is fixed on the top surface of the partition plate by screws, that is, the electric control power module 7 is located in the upper space of the electric control housing 2. The power supply module 3 is fixed on the bottom surface of the partition plate by screws, that is, the power supply module 3 is located in the lower space of the electric control housing 2. The electric control power module 7 is cooled by an electric control cooling water channel, and the power supply module 3 is cooled by a power supply cooling water channel.

[0052] In the embodiment of the present application, the flow direction of the coolant is as follows:

[0053] The coolant enters the power supply cooling water channel located in the upper layer of the electric control housing 2 through the water inlet nozzle 6, and then is divided into multiple branches through the parallel first water channel to cool the power supply module 3, and the flow rate of each branch is uniform. Subsequently, it enters the electric control cooling water channel located in the lower layer of the electric control housing 2, and is divided into multiple branches through the parallel second water channel, and the flow rate of each branch is uniform to cool the electric control power module 7. Finally, it flows out through the water outlet nozzle 5.

[0054] In the embodiment of the present application, an automobile adopts the integrated electric drive controller in the embodiment of the present application.
