The air provided by the external air source enters the inner cavity from the air inlet, enters the outer cavity through the air guide holes of the upper air duct plate 3, and then returns to the inner cavity again after passing through the air guide holes 13 of the back air duct plate 8. That is, the gas entering the inner cavity flows through the air guide hole of the first section, the gap between the second section and the box body 1, the gap between the third section and the box body 1, the gap between the fourth section and the box body 1, and the air guide hole 13 of the fourth section in sequence, and then returns to the inner cavity again, thus directionally circulating.

As an example, the cell factory 12 is plural in number.
In one example, a plurality of the cell factories 12 can be provided independently.
