As can be seen from the figure, the integrated controller is provided with two covers, namely an electric control upper cover 1 and a power distribution upper cover 14. The distribution chamber is last to be arranged direct current charging wire 10, PTC wire nose 11, air condition compressor wire nose 12 and direct current generating line 13, direct current charging wire 10, PTC wire nose 11, air condition compressor wire nose 12 and direct current generating line 13 can be arranged along the circumference of distribution chamber in proper order, refer to figure 1, there are direct current charging wire 10 around the distribution upper cover 14, PTC wire nose 11, air condition compressor wire nose 12 and direct current generating line 13, these pencil are concentrated around distribution upper cover 14, be favorable to only opening distribution upper cover 14 and just can install. An alternating current charging wire 15 is arranged beside the direct current bus 13, and an alternating current charging upper cover 16 is arranged on the electric control upper cover 1 for facilitating the disassembly of the alternating current charging wire 15. The ac charging upper cover 16 can be opened independently, and specifically, the ac charging upper cover 16 is provided to be openably attached to the electrically controlled upper cover.

Fig. 2 to 4 are schematic views of a water course of the integrated controller.

Fig. 2 is a schematic diagram of the structure and flow direction of the IGBT water channel, and from this schematic diagram, we can see that the cooling water flows from the water channel inlet 17 (inlet of the first heat dissipation channel) and then flows along the IGBT water channel plate 18, the water channel block 21, the water channel hidden channel 22, and then flows from the water channel hidden channel 22 to the MOS tube water channel 24 through the water through hole. As can be seen from the figure, the water through hole is located below one end of the water channel hidden channel 22, namely one corner of the IGBT water channel. Thus, the cooling water can completely cool the IGBT29 and then flow from the water through hole to the MOS transistor water channel 24. It can also be seen from this figure that the water channel 22 is part of the structure on the housing 2, which is machined by CNC machining with a T-shaped tool, which saves space or corresponding parts of the housing 2. Wherein, IGBT water course, water course hidden channel 22 are contained in the inlet channel.

Fig. 3 is a schematic diagram of the structure and flow direction of the MOS tube water channel 24, and referring to fig. 2, after cooling water flows into the MOS tube water channel 24 through the water hole, because the MOS tube water channel guide rib a25 and the MOS tube water channel guide rib b26 are additionally arranged in the MOS tube water channel 24, water flows out from the water channel water outlet 27 after passing through the MOS tube water channel guide rib a25 and the MOS tube water channel guide rib b 26. A MOS tube water channel cover plate 23 is arranged above the MOS tube water channel 24 and is welded on the shell 2 in an economic and environment-friendly friction welding mode. Wherein, the MOS tube water channel 24 is contained in the liquid outlet channel.

Fig. 4 is a schematic diagram showing a cut-away of the water channel of the integrated controller, from which the functions of the IGBT water channel water adding channel block 21 and the water channel dark channel 22 can be further seen: after flowing into the IGBT water channel from the controller water inlet pipe 3, the cooling water flows along the IGBT water channel plate 18 and the IGBT water channel block 21 to the water channel dark channel 22. The IGBT water channel block 21 prevents the cooling water from flowing to the area and then releasing the pressure, which results in poor cooling of the heat dissipation pins of the row IGBT29 above the IGBT water channel block 21. The water channel hidden channel 22 is also used for allowing the cooling water to completely flow into the region after passing through the heat dissipation pins of the IGBT29, and then flow to the MOS tube water channel 24 through the water channel through holes 20. Assuming that the IGBT water channel has no water channel blind channel 22, the water channel via holes 20 can only be formed at the corners of the IGBT water channel block 21, so that the heat dissipation pins of the IGBT29 will not be well dissipated. The waterway blind 22 not only allows the cooling water to completely pass through the IGBT29 for cooling, but also saves the space of the housing 2 and eliminates the possibility of using a waterway cover for this function. In conclusion, the electric control IGBT29 and the water channel of the MOS tube heating device of the power supply are connected into a whole, and the sharing of the water channel is realized.

Fig. 5 and 6 show the structure of the multifunctional electric control shell 2. It can be seen from the figure that the multifunctional electronic control housing 2 includes an OBC filtering cavity 35, the OBC filtering cavity 35 is separated by a shielding cover 34 into an independent closed cavity, so as to prevent the electronic devices in a new cavity, i.e. a low-voltage signal control cavity 36, formed above the shielding cover 34 and in the area of the isolation rib from being interfered, that is, the shielding cover 34 separates the low-voltage signal control cavity 36 and the OBC filtering cavity 35, wherein the low-voltage signal control cavity 36 and the OBC filtering cavity 35 are stacked up and down, and optionally, the low-voltage signal control cavity 36 is located above the OBC filtering cavity 35. The shielding cover 34 is further provided with a second isolation rib 63, and the second isolation rib 63 and a part of the side wall of the housing 2 enclose an ac charging inlet isolation cavity 64, so that interference of external current on an internal power supply and an electric control during ac charging can be prevented. The low-voltage signal control chamber 36 is opposite to the electric control chamber 41, and the electric control chamber is separated by the isolation rib so as to prevent high-voltage devices in the electric control chamber 41 from interfering with the low-voltage signal. The electric control chamber 41 is provided with a water channel water inlet 17, a water channel water outlet 27, the aforementioned water channel block fixing screw 19, a water channel through hole 20, an IGBT water channel block 21 and a water channel dark channel 22. The side edges of the low-voltage signal control cavity 36 and the electric control cavity 41 are power distribution cavities, and a power distribution wire passing hole and an electric control distribution wire passing hole 40 are respectively arranged between the power distribution cavities and are used for connecting a power distribution module with an electric control circuit of a power supply. The low-voltage signal control cavity 36 and the lower part of the electric control cavity 41 are separated by an IGBT water channel and an MOS pipe water channel 24 to form a lower cavity, namely an OBC power module cavity 42. There is MOS pipe water course 24 in the OBC power module cavity 42, has on the MOS pipe water course 24 through MOS pipe water way direction muscle a25 and MOS pipe water way direction muscle b26, thereby the cooling water can let the cooling water pass through MOS pipe water way 24 region relatively evenly through these direction muscle thereby make the even cooling of MOS pipe on the MOS pipe water way apron 23. And a power transformer encapsulating cavity 43, a power DC inductor encapsulating cavity 44 and a power step-down transformer encapsulating cavity 45 are respectively arranged at two sides of the MOS pipe water channel 24. There are also 2 conductive post vias 46 on the housing 2 for conducting the power module to the filter PCB circuit. A small isolation area is a DC output isolation cavity 47 beside the OBC power module cavity 42, which is used for preventing the DC current converted by the power supply DC module from being interfered by the OBC power module when being converted again to supply power to the whole vehicle. In conclusion, the shell 2 is ingeniously separated into 7 chambers, so that the interference of the high-voltage module on the low-voltage module is prevented, and the EMC effect is greatly improved. Meanwhile, the IGBT water channel and the MOS pipe water channel 24 are connected into an integral water channel through the water channel hidden channel 22 and the water channel through hole 20, so that the water pipe connection of each water channel is reduced, and the space and the cost are saved. The power transformer encapsulation cavity 43, the power DC inductor encapsulation cavity 44 and the power step-down transformer encapsulation cavity 45 are respectively arranged at two sides of the MOS tube water channel 24, and can also allow these electronic devices to be in close contact for heat dissipation.

It should be noted that, the present invention utilizes water as the heat transfer medium during the description process, but the protection scope of the present invention is not limited thereto, and the present invention can also utilize other heat transfer media to perform heat transfer.

The utility model discloses, power and automatically controlled casing integration. The water channel in the integrated shell is shared, the IGBT water channel is combined with the MOS tube 33 cooling water channel through the communication of the dark water channel, and the power supply electric control cavity, the power supply transformer encapsulation cavity 43, the power supply step-down transformer encapsulation cavity 45 and the power supply DC inductor encapsulation cavity 44 are arranged around the two water channels, so that the purpose that one water channel dissipates heat for a plurality of heat dissipation devices is achieved, and the water channel connection structural members of the related water channels are reduced. The housing 2 is divided into several small chambers for EMC passage. After the power supply and the electric control shell 2 are integrated, the power supply and the electric control can share a direct current bus and a signal connector (a direct current bus, a signal connector and connecting wires thereof are omitted). The power distribution module is independently opened, so that the whole vehicle is convenient to assemble, and a large cover is not required to be opened during the whole vehicle assembly, so that electronic devices electrically controlled by a power supply are not damaged; the independent opening of the small cover of the power distribution module is also beneficial to after-sale maintenance: for example, when the safety device 89 is replaced or the vehicle needs to be powered off in maintenance, the operation can be completed only by opening the small cover.
