Air heat exchange device and air heat exchange system thereof

The invention provides an air heat exchange device and an air heat exchange system thereof. The air heat exchange device comprises a box, the box comprises a steam snake-shaped array pipe coiled in the box, and the steam snake-shaped array pipe comprises a steam inlet and a condensed water outlet both stretching out of the box; the box also comprises a liquid ammonia snake-shaped array pipe coiled in the box, and the liquid ammonia snake-shaped array pipe comprises a liquid ammonia inlet and a liquid ammonia outlet both stretching out of the box; and the top of the box is provided with an air inlet and the bottom of the box is provided with an air outlet. According to the technical scheme, compared with the technology that a heating array pipe is inbuilt in a stock bin for indirectly heating aggregates, the new technology of heating the aggregates by wind is developed. The new approach capable of cooling the aggregates and heating the aggregates in the aggregate stock bin is realized, so that the arrangement
