However, the water channel of the existing water-cooling heat dissipation component is usually horizontally coiled at the bottom of the control box, so it can only dissipate heat for the control module attached to the bottom of the control box, but cannot meet the heat dissipation requirements of multiple control modules arranged vertically, which greatly affects the heat dissipation effect of the water-cooling heat dissipation component. Summary of the invention

[0005] This new type of application adopts the following technical solutions:

DETAILED DESCRIPTION
[0024] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.
[0025] like Figures 1 to 3 As shown, an all-in-one controller with a new water channel structure includes a control box 1, a water cooling plate 2 is arranged in the middle of the control box 1, and the water cooling plate 2 separates the control box 1 into an upper box body 11 and a lower box body 12. A first control module (not shown in the figure) is arranged in the upper box body 11, and a second control module (not shown in the figure) is arranged in the lower box body 12; a water channel for dissipating heat for the first control module and the second control module at the same time is arranged in the water cooling plate 2. The water cooling plate 2 of the utility model is arranged in the middle of the control box 1, so that the control modules in the upper box body 11 and the lower box body 12 can be evenly dissipated at the same time, ensuring that the water cooling plate 2 fits each of the control modules arranged longitudinally, thereby achieving an ideal heat dissipation effect.
[0026] like Figure 2 and Figure 3As shown, a heat dissipation component is provided in the water channel, and the heat dissipation component includes heat dissipation ribs and heat dissipation fins that cooperate with each other, wherein the heat dissipation ribs can divide the water channel into multiple channels, so that the coolant passes through the channels evenly and quickly, thereby effectively reducing the water resistance; the heat dissipation fins can fully contact with the coolant, thereby achieving local rapid heat exchange. The heat dissipation fins in the utility model adopt polygonal fins. Compared with traditional circular fins, polygonal fins have a larger heat dissipation area and can fully contact with the coolant in the water channel, thereby achieving efficient heat exchange and effectively improving the heat dissipation effect of the water-cooled plate 2.
[0027] like Figures 1 to 3 As shown, the same side wall of the control box 1 is provided with a water inlet 13 and a water outlet 14, and the two ends of the water channel are respectively connected to the water inlet 13 and the water outlet 14, and are divided into a U-shaped water channel by a partition plate 20. The water channel is provided with a first heat dissipation zone 21, a second heat dissipation zone 22, a third heat dissipation zone 23 and a fourth heat dissipation zone 24 in sequence along its flow direction; a plurality of first heat dissipation fins 211 and a plurality of first heat dissipation ribs 212 are respectively provided on both sides of the first heat dissipation zone 21; a plurality of second heat dissipation ribs 221 are provided in the second heat dissipation zone 22; a plurality of third heat dissipation ribs 231 are provided in the third heat dissipation zone 23; a plurality of fourth heat dissipation ribs 241 and a plurality of second heat dissipation fins 242 are respectively provided on both sides of the fourth heat dissipation zone 24. In addition, the water channel also includes a fifth heat dissipation zone 25 arranged beside the second heat dissipation zone 22, and a plurality of fifth heat dissipation ribs 251 are provided in the fifth heat dissipation zone 25. Due to the different designs of the heat dissipation components, each heat dissipation zone has different heat dissipation capabilities, so that it can be adapted to control modules with different heat generation, thereby effectively reducing water resistance while achieving targeted and efficient heat dissipation.
[0028] like Figures 1 to 3As shown, specifically, the first control module located in the upper box body 11 includes an MCU driver module, a PDU module and a relay group, and the second control module located in the lower box body 12 includes a two-in-one integrated DCDC module and an OBC module. Among them, the MCU driver module has the largest heat generation, and its main heat source is the IGBT component. Therefore, in this embodiment, the MCU driver module is arranged at the corresponding position of the first heat dissipation zone 21 with the highest heat dissipation capacity, and the IGBT component of the MCU driver module is located at the corresponding position of the first heat dissipation fins 211. The heat generation of the PDU module is relatively small, so in this embodiment, the PDU module is arranged at the corresponding position of the second heat dissipation zone 22 with relatively low heat dissipation capacity. The heat generation of the DCDC module is also relatively small, so in this embodiment, it is arranged at the corresponding position of the third heat dissipation zone 23. The heat generation of the OBC module is relatively large, so in this embodiment, it is arranged at the corresponding position of the fourth heat dissipation zone 24, and the MOS tube, the main heat generating component of the OBC module, is located at the corresponding position of the second heat dissipation fins 242. The heat generation of the relay group is also relatively small, because in this embodiment, the relay group is arranged at the corresponding position of the fifth heat dissipation zone 25.
[0029] like Figure 2 As shown, in order to ensure smooth flow of coolant in each heat dissipation zone, a plurality of guide bars 261 for guiding flow are provided between the first heat dissipation zone 21 and the second heat dissipation zone 22 in this embodiment, and the guide bars 261 are rectangular bars with guide portions at both ends.
[0030] like Figure 2 As shown, as a preferred solution: the first heat dissipation rib 212, the third heat dissipation rib 231 and the fourth heat dissipation rib 241 are all rectangular heat dissipation bars with guide parts at both ends, the second heat dissipation rib 221 is an arc-shaped heat dissipation bar with its own guide function, the fifth heat dissipation rib 251 is an L-shaped heat dissipation bar, and the first heat dissipation fin 211 and the second heat dissipation fin 242 are both hexagonal fins. Through simulation experiments, it is known that the heat dissipation component structure provided by this embodiment can achieve the most ideal heat exchange effect of the water-cooled plate 2.
[0031] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
