Example 11

As shown in fig. 1, the present embodiment provides an electric vehicle 100 mainly including three parts: a simplified electrical box 120, a separate cooling assembly 130, and a platformized chassis 110. The electric box 120 is arranged without considering the arrangement design of the water cooling pipes because the traditional water cooling assembly is stripped, and the electric box 120 can be more closely arranged on the independent cooling assembly 130. Independent cooling assemblies 130 can be designed through integration, so that one cooling assembly 130 can support the installation and heat dissipation requirements of a plurality of electric boxes 120, and the integration efficiency is improved. The cooling assembly 130 is mainly composed of a cooling plate 132, and a second heat-conducting medium 138 is disposed between the cooling plate 132 and the electrical box 120, and the second heat-conducting medium 138 can be used for conducting heat to the box body 122.

As shown in fig. 5 and 6, in order to better integrate the cooling assembly 130 and the electrical box 120, a single electrical box region 114 can be designed separately on the flatbed chassis 110 as a layout region, facilitating efficient integration of the battery system. The chassis 110 is mainly composed of a frame 112, and the frame 112 is designed in a platform mode, so that the cooling assembly 130 and the electric box 120 can be better integrated. Wherein, the main characteristics of the simplified electronic box 120 are: the electric box 120 does not have a conventional water cooling assembly, the electric core pack 126 transfers heat to the bottom plate 1222 of the box body 122 through the first heat-conducting medium 124, and the bottom plate 1222 serves both as a heat-transferring medium and as a support for the installation of the electric core pack 126. The arrangement of the arrangement regions of the electrical boxes 120 is performed on the chassis 110 alone, and the arrangement regions of different specifications are designed as the electrical box regions 114 in conjunction with the sizes of the electrical boxes 120, so that the arrangement of different numbers of electrical boxes 120 can be supported. The expandability of the electronic box area 114 can support the requirements of different electric quantities of the vehicle, and meet different cruising requirements of the vehicle. As shown in fig. 3, the independent cooling module 130 is composed of a cooling plate 132, a first nozzle 134, a second nozzle 136, and the like, and a second heat transfer medium 138 may be mounted on the electrical box 120. When the electrical box 120 is installed on the cooling assembly 130, the heat transfer path of the electrical core assembly 126 is: the electric core group 126, the first heat-conducting medium 124, the bottom plate 1222, the second heat-conducting medium 138, the cooling plate 132 and the cooling liquid. With reference to the size of the electrical boxes 120, the cooling assembly 130 can be designed to different specifications to support different number of electrical boxes 120 to meet different electric quantity and mileage requirements of the vehicle, and to support expansion of the vehicle.

On the other hand, the electrical box 120 is designed simply, for example, the cooling assembly 130 of the current battery box is stripped off and separated into one component. Since the electric boxes 120 are individual energy modules, different electric vehicles 100 require different numbers of electric boxes 120 according to different demands for electric power. The second heat transfer medium 138 is provided in a corresponding number according to the number of the electronic boxes 120, and adaptability is improved. Since the electrical boxes 120 are arranged without considering the connection and piping arrangement of the cooling module 130, the plurality of electrical boxes 120 can be arranged more closely to each other, thereby improving the degree of integration. The cooling module 130 separated into individual modules can also improve the integration degree of the cooling module 130 with the whole vehicle through an integrated design. The arrangement of the electrical box area 114 on the chassis 110 can improve the integration efficiency of the chassis 110, and has expandability, and supports the integration of different numbers of electrical boxes 120, so as to meet the requirements of the electric vehicle 100 on different electric quantities and mileage.

To sum up, according to the utility model discloses a beneficial effect of embodiment does:

the electric box 120 and the cooling assembly 130 are independent of each other, the cooling assembly 130 is arranged outside the electric box 120, the arrangement design of water cooling pipes does not need to be considered when the electric box 120 is arranged, and the integration efficiency is improved.
