[0056] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered part of the specification.

[0057] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0058] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0059] The box assembly 100 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0060] like Figures 1 to 6 As shown, the box assembly 100 according to an embodiment of the present invention includes an electric control box 10 and a power supply box 20 .

[0061] Specifically, an electric control module is provided in the electric control box 10, and the electric control box 10 is provided with a first flow channel 16 for cooling the electric control module. A power module 200 is provided in the power box 20, and the power box 20 is provided with a second flow channel 21 for cooling the power module 200. The power box 20 is fixed to the electric control box 10.

[0062] In other words, if Figures 1 to 6 As shown, the box assembly 100 according to the embodiment of the present invention mainly includes two independent boxes, specifically an electric control box 10 and a power supply box 20. The electric control box 10 can be fixedly connected to the electric control module, and the electric control box 10 is provided with a first flow channel 16 suitable for circulating cooling liquid. The electric control module can be cooled by the first flow channel 16 of the electric control box 10. The power supply box 20 can be fixedly installed on the electric control box 10 by fasteners (for example, screws, etc.). The power supply box 20 can be fixedly connected to the power supply module 200, and the power supply box 20 is provided with a second flow channel 21 suitable for circulating cooling liquid, so that the power supply module 200 can be cooled by the second flow channel 21 of the power supply box 20.

[0063] Therefore, according to the box assembly 100 of the embodiment of the present invention, the electric drive controller is integrated by setting an independent electric control box 10 and a power supply box 20 that are fixedly connected to each other, and a first flow channel 16 is set on the electric control box 10 and a second flow channel 21 is set on the power supply box 20, so that the box assembly 100 is modularized. When the cooling requirements of the power module 200 or the electric control module (for example, the installation position of the part to be cooled on the power module 200 or the electric control module) change, it is only necessary to carry out separate development and design for the affected electric control box 10 or power supply box 20 without the need for comprehensive adjustment of the entire structure, which effectively improves the flexibility and efficiency of the design and effectively reduces the additional cost caused by changes in the cooling requirements of the power module 200 or the electric control module.

[0064] According to one embodiment of the utility model, the first end of the first flow channel 16 is communicated with the first end of the second flow channel 21, and the first flow channel 16 and the second flow channel 21 are both communicated between the first channel port 12 and the second channel port 13, one of the first channel port 12 and the second channel port 13 is used for fluid to enter the box assembly 100, and the other of the first channel port 12 and the second channel port 13 is used for fluid to flow out of the box assembly 100.

[0065] Specifically, the box assembly 100 is provided with the first channel port 12 and the second channel port 13, the first end of the first flow channel 16 can be communicated with the first end of the second flow channel 21, and the first flow channel 16 and the second flow channel 21 can both be communicated with the first channel port 12 and the second channel port 13, so that the fluid can enter the first flow channel 16 and the second flow channel 21 of the box assembly 100 from the first channel port 12, and the fluid can flow out of the first flow channel 16 and the second flow channel 21 of the box assembly 100 from the second channel port 13, or the fluid can enter the first flow channel 16 and the second flow channel 21 of the box assembly 100 from the second channel port 13, and the fluid can flow out of the first flow channel 16 and the second flow channel 21 of the box assembly 100 from the first channel port 12.

[0066] In the embodiment, the first flow channel 16 and the second flow channel 21 can share the first channel port 12 and the second channel port 13, effectively simplifying the overall structure of the box assembly 100.

[0067] In some specific examples of the utility model, the first channel port 12 and the second channel port 13 are both arranged on the electric control box 10 or the power supply box 20.

[0068] That is to say, as shown in Figure 2 and Figure 3 , the first channel port 12 and the second channel port 13 can be arranged on one structural member, that is, the first channel port 12 and the second channel port 13 can both be arranged on the electric control box 10, or the first channel port 12 and the second channel port 13 can both be arranged on the power supply box 20.

[0069] In the example, by arranging the first channel port 12 and the second channel port 13 on one structural member, when the cooling liquid interface of the external cooling liquid system and the box assembly 100 changes, for example, the interface position or the interface size changes, only one of the electric control box 10 or the power supply box 20 needs to be adjusted and redesigned, further reducing the design and development cost.

[0070] In some optional examples of the utility model, the first end of the first flow channel 16 is communicated with the first end of the second flow channel 21, the first channel port 12 is communicated with the second end of the first flow channel 16, and the second channel port 13 is communicated with the second end of the second flow channel 21.

[0071] In one example, the first channel opening 12 can serve as a fluid inlet, the second channel opening 13 can serve as a fluid outlet, and the fluid can flow from the first channel opening 12 to the second end of the first flow channel 16, from the second end of the first flow channel 16 to the first end of the second flow channel 21, from the first end of the second flow channel 21 to the second end of the second flow channel 21, and from the second end of the second flow channel 21 to the second channel opening 13, so that the fluid flows out of the second channel opening 13.

[0072] In another example, the second channel opening 13 can serve as a fluid inlet, the first channel opening 12 can serve as a fluid outlet, and the fluid can flow in the opposite direction to the flow direction in the previous example, which will not be described again.

[0073] Thus, the first flow channel 16 and the second flow channel 21 form a series flow path, which is simple in structure and conducive to production and manufacture.

[0074] In some embodiments of the utility model, one side of the power box 20 is provided with a first mounting space, and the side of the second flow channel 21 away from the first mounting space is provided with a second mounting space.

[0075] That is, the second flow channel 21 has a first side and a second side arranged oppositely, one side of the power box 20 is provided with a first mounting space, the first mounting space can be located on the first side of the second flow channel 21, and the power box 20 is provided with a second mounting space on the second side of the second flow channel 21, so that the second flow channel 21 can cool the components in the first mounting space and the second mounting space.

[0076] In some optional examples of the utility model, the first side of the electric control box 10 is fixed to the power box 20, and the first flow channel 16 is arranged adjacent to the first side of the electric control box 10.

[0077] Specifically, the side of the electric control box 10 facing downward can be the first side of the electric control box 10, the first side of the electric control box 10 can be fixedly connected with the power box 20, and the first flow channel 16 is arranged adjacent to the first side of the electric control box 10, that is, the distance between the first flow channel 16 and the first side of the electric control box 10 is relatively close, for example, the first flow channel 16 is arranged on the wall of the electric control box 10 close to the power box 20, so that the first flow channel 16 can cool the components in the electric control box 10 and also can cool the components in the power box 20 to a certain extent.

[0078] In some embodiments of the utility model, the first side of the electric control box 10 is fixed to the power box 20, and the first mounting space is adjacent to the first side of the electric control box 10.

[0079] In detail, the side of the electric control box body 10 facing downwards can be the first side of the electric control box body 10, the first side of the electric control box body 10 can be fixedly connected with the power box body 20 together, and the first installation space is adjacent to the first side of the electric control box body 10, that is, the wall surface of the electric control box body 10 can serve as the wall surface of the first installation space, so that the first flow channel 16 can not only cool the components in the electric control box body 10, but also cool the components in the first installation space.

[0080] In the embodiment, the components in the first installation space can be cooled not only by the first flow channel 16 but also by the second flow channel 21, so that the cooling effect of the components in the first installation space can be ensured.

[0081] In some optional examples of the utility model, the first side of the electric control box body 10 is fixed to the power box body 20, the electric control box body 10 is provided with a third flow channel 11, and the third flow channel 11 is arranged adjacent to the first side of the electric control box body 10.

[0082] That is, the side of the electric control box body 10 facing downwards can be the first side of the electric control box body 10, the first side of the electric control box body 10 can be fixedly connected with the power box body 20 together, the electric control box body 10 can be further provided with a third flow channel 11, and the third flow channel 11 is arranged adjacent to the first side of the electric control box body 10, that is, the third flow channel 11 can be arranged on the wall body of the electric control box body 10 close to the first side of the electric control box body 10, so that the third flow channel 11 can not only cool the components on the electric control box body 10, but also cool the components on the power box body 20.

[0083] It should be noted that the first flow channel 16 is mainly used for cooling the electric control module, and the second flow channel 21 is mainly used for cooling the power module, therefore, when the cooling requirement (cooling space layout, etc.) of one of the electric control module and the power module changes, only one of the electric control box body 10 and the power box body 20 needs to be redesigned and developed. The cooling of the power module by the first flow channel 16 is auxiliary cooling, and has little influence on the cooling of the power module 200, therefore, when the cooling requirement of the power module 200 changes, the influence of the adjustment of the first flow channel 16 on the satisfaction of the cooling requirement of the power module 200 is small, and thus the first flow channel 16 does not need to be adjusted. The cooling of the electric control module and the power module 200 by the third flow channel 11 is also auxiliary cooling, and when the cooling requirement of the power module 200 or the electric control module changes, the influence of the adjustment of the third flow channel 11 on the satisfaction of the cooling requirement of the power module 200 or the electric control module is small, and thus the third flow channel 11 does not need to be adjusted.

[0084] In some embodiments of the utility model, the first end of the third flow channel 11 is in communication with the second end of the second flow channel 21, and the second end of the third flow channel 11 is in communication with the second channel opening 13.

[0085] Specifically, the first channel port 12 and the second channel port 13 are arranged on the electric control box body 10, and the second end of the second flow channel 21 can be communicated with the second channel port 13 through the third flow channel 11, that is, the first end of the third flow channel 11 is communicated with the second end of the second flow channel 21, and the second end of the third flow channel 11 is communicated with the second channel port 13.

[0086] In one example, the first channel port 12 can be used as a fluid inlet, and the second channel port 13 can be used as a fluid outlet, and the fluid can flow from the first channel port 12 to the second end of the first flow channel 16, then flow from the second end of the first flow channel 16 to the first end of the second flow channel 21, then flow from the first end of the second flow channel 21 to the second end of the second flow channel 21, then flow from the second end of the second flow channel 21 to the first end of the third flow channel 11, then flow from the first end of the third flow channel 11 to the second end of the third flow channel 11, and then flow from the second end of the third flow channel 11 to the second channel port 13, so that the fluid flows out of the second channel port 13.

[0087] In another example, the second channel port 13 can be used as a fluid inlet, and the first channel port 12 can be used as a fluid outlet, and the flow direction of the fluid is opposite to that of the previous example, which will not be described here.

[0088] Therefore, the first flow channel 16, the second flow channel 21 and the third flow channel 11 form a series flow path, which is simple in structure, beneficial to production and manufacturing, and beneficial to arranging the first channel port 12 and the second channel port 13 on the electric control box body 10.

[0089] In some optional examples of the present application, the first flow channel 16, the second flow channel 21 and the third flow channel 11 are all planar flow channels.

[0090] In this example, the planar flow channel means that the flow direction of each point in the flow channel is parallel to a plane, which can avoid the flow channel structure being too complex, is beneficial to subsequent production and processing, and can also increase the heat dissipation area and improve the cooling effect.

[0091] According to some embodiments of the present application, the side of the electric control box body 10 away from the power supply box body 20 is provided with a first groove body 154, and the first groove body 154 and the electric control module define the first flow channel 16; the electric control box body 10 is provided with a first connecting groove 152 and a second connecting groove 153, the first connecting groove 152 communicates the first groove body 154 with the second flow channel 21, and the second connecting groove 153 communicates the first groove body 154 with the first channel port 12.

[0092] That is, the first groove body 154 can be formed in a cuboid structure, and the first connecting groove 152 and the second connecting groove 153 are arranged on the side of the cover plate 15 close to the base plate 14, the first connecting groove 152 can be in communication with the first end of the second flow channel 21, and the second connecting groove 153 can be in communication with the first channel opening 12, so as to realize the communication of the first flow channel 16 with the second flow channel 21 and the first channel opening 12. For example, in use, the opening of the first groove body 154 can be covered by an IGBT module (i.e., an insulated gate bipolar transistor power module) of an electric control module, so that the electric control module and the inner wall surface of the first groove body 154 define the first flow channel 16, thereby simplifying the processing mode of the first flow channel 16, facilitating production and processing, and reducing production cost.

[0093] According to an embodiment of the utility model, the electric control box body 10 has the base plate 14, the power supply box body 20 is connected on the base plate 14, and the electric control box body 10 further comprises: the cover plate 15, which is arranged on the side of the base plate 14 away from the power supply box body 20, and the cover plate 15 is provided with the first groove body 154 on the side away from the base plate 14, and the cover plate 15 is provided with the first connecting groove 152 and the second connecting groove 153 on the side close to the base plate 14.
