The isolation box 1 includes a lower box body 12 with an open side and a box cover 11. The mounting plate 13 is detachably connected to the inner side wall of the lower box body 12 to divide the lower box body 12 into at least two layers. The BMS 4, the filter 5, the boost-buck charging module 6 and the inverter 7 are evenly arranged on both sides of the mounting plate 13 and integrated with the mounting plate 13 in the isolation box 1.

For example, a single, two or three mounting plates 13 are used to divide the lower box body 12 into different layers, and different devices are installed between different layers to ensure electromagnetic signal isolation between different devices. However, according to the specific design scheme, a single mounting plate 13 is preferred in this application to fully utilize the space of the isolation box 1 and avoid increasing the height of the isolation box 1 beyond the requirement.

When the heat dissipation pieces 3 are air-cooled, a fan is mounted on the heat dissipation plates 121 on the two sides of the lower box body 12. When the fan is started, external air is sucked into the lower box body 12. At this time, the air flows into different layers of the mounting plate 13, so that the air passes through the BMS 4, the filter 5, the boost-charging module 6 and the inverter 7, and the heat generated by the above components is discharged from the fan on the other side, so as to ensure the temperature in the isolation box 1 and avoid the temperature of the isolation box 1 being too high. In addition to the fan, a refrigeration piece can be additionally provided. When the fan blows, cold air is discharged into the isolation box 1 to further improve the cooling effect. When the heat dissipation pieces 3 are water-cooled, a liquid pump and a liquid tank are mounted on the heat dissipation plates 121. The pipe body penetrates from the side wall of the lower box body 12 to the other side, and the fan is used to dissipate heat of the liquid after heat absorption to ensure that the cold liquid absorbs heat in the isolation box 1, so as to keep the temperature of the isolation box 1 in a balanced state.
