In order to overcome the defects, forced air cooling is an ideal cooling mode of the large-capacity SVG. In a forced air cooling system, because the power modules of the large-capacity SVG are numerous, the number of power cabinets is large. For the high-power SVG, the heating power is high during normal operation, and if the air intake in each power cabinet is different, the local temperature of some cabinets is too high. The cabinets are a great hidden trouble for long-time running of the SVG. In addition, the power module in the SVG cabinet body has higher requirement on the cleanness degree of air. This therefore places a relatively tight demand on the air-cooled system.
A few colleges and scientific research units at home and abroad carry out related research on the cooling system of the SVG. But has the following disadvantages: 1) a sealed heat exchange structure is not designed, so that the power module in the SVG cabinet is always in a dustless working state, and the large-capacity SVG cannot stably run for a long time. 2) The air quantity equalizing measure among the SVG cabinet bodies is only limited to the design of the shape of the air channel, and a special device structure is not designed to equally divide the air quantity of each SVG cabinet. 3) The heat generated by the SVG cabinet body is not further utilized, and the energy waste is caused.
