[0025] In this embodiment: the spraying structure includes a condensing box 101, two air exchange windows 102 are symmetrically arranged at the bottom of the condensing box 101, a water delivery pipe 103 is arranged on one side of the condensing box 101, a water pump 104 is installed on the water delivery pipe 103, a spray pipe 105 is arranged at the top end of the water delivery pipe 103, five spray heads 106 are uniformly arranged on the spray pipe 105, a first filler 107 is arranged above the spray pipe 105, and a second filler 108 is arranged below the spray pipe 105. The first filler 107 is arranged above the air exchange window 102, and the first filler 107 and the second filler 108 are both porous structures. The water pump 104 works to send the cooling water at the bottom of the condensing box 101 into the spray pipe 105 through the water delivery pipe 103, and spray the water downward through the spray heads 106 to spray and heat exchange the surface of the water spraying heat exchange structure. In this process, the air exchange structure inhales cold air through the air exchange window 102 to make the air in the condensing box 101 flow upward, thereby improving the cooling effect. After heat exchange, the cooling water falls on the second filler 108 and is uniformly distributed in the porous structure inside the second filler 108, so as to quickly exchange heat with the upward flowing cold air to achieve rapid cooling of the cooling water, so as to continuously provide low-temperature cooling water for circulation spraying. At the same time, the top of the condensing box 101 is provided with the porous first filler 107, which can effectively contact with the upward flowing air in the condensing box 101 to intercept the water vapor carried by the air and reduce the loss of cooling water.

The guide plate 205 is in the shape of a broken line, and the heat exchange pipe 201 passes through the inside of the twelve guide plates 205 in a serpentine shape. The fins 204 are circular in shape and are uniformly distributed on the surface of the heat exchange pipe 201. High-temperature gas is introduced into the heat exchange pipe 201 through the air inlet pipe 202 and is discharged from the air outlet pipe 203. In this process, the spray heads 106 spray water on the surface of the heat exchange pipe 201 and the fins 204.
