[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a cooling device for a classifying air blower includes a cooling box 1, a circulating pump 2 mounted on the cooling box 1, and a conveying pipe 3 connected to the circulating pump 2. A heat exchange structure 4 is connected to the end of the conveying pipe 3, and a connecting structure 5 is provided on the heat exchange structure 4. A fixing plate is provided on the side of the cooling box 1, and the circulating pump 2 is mounted on the fixing plate. A connecting pipe is provided on the cooling box 1 and connected to the circulating pump 2. A box cover 6 is provided at the top of the cooling box 1, and a recovery pipe 7 is connected to the box cover 6. The end of the recovery pipe 7 is connected to the heat exchange structure 4.

[0020] When using the cooling device, the heat exchange structure 4 is installed to the air inlet of the fan via the connecting structure 5. The delivery pipe 3 and the recovery pipe 7 are connected to the heat exchange structure 4, and the device is put into use after the power is turned on. During the operation of the fan, the cooling water inside the cooling tank 1 enters the heat exchange structure 4 through the delivery pipe 3 under the action of the circulating pump 2. At the same time, the outside air drawn in by the fan passes through the heat exchange structure 4 and the connecting structure 5 into the fan. During this process, the outside air comes into contact with the heat exchange structure 4, and the cooling water exchanges heat with the outside air. The temperature of the cooling water rises and enters the cooling tank 1 through the recovery pipe 7 for cooling. The temperature of the outside air rises and enters the fan. While providing airflow, the cooling water also cools the internal components of the fan, thus achieving the cooling of the fan. The cooling tank 1 cools the water, and the circulating pump 2 circulates the water, allowing for continuous cooling of the fan.

[0021] Through the above implementation, the heat exchange structure 4 includes a fixed frame 401 and a wave heat exchange plate 402, the wave heat exchange plate 402 is fixedly installed in the inside of the fixed frame 401, and the fixed frame 401 is communicated with the wave heat exchange plate 402. The heat exchange structure 4 further includes a cavity 403, a heat exchange cavity 404, a water inlet joint 405 and a water outlet joint 406, the cavity 403 is opened on the fixed frame 401, the heat exchange cavity 404 is opened on the wave heat exchange plate 402, and the heat exchange cavity 404 is communicated with the cavity 403, the water inlet joint 405 is fixed at the lower end of the fixed frame 401, the water outlet joint 406 is fixed at the upper end of the fixed frame 401, and the water inlet joint 405, the water outlet joint 406 and the cavity 403 are communicated.

[0022] When the fan is cooled, the cooling water in the conveying pipe 3 enters the cavity 403 on the fixed frame 401 from the water inlet joint 405, and then enters the heat exchange cavity 404 on the wave heat exchange plate 402. The external air contacts the wave heat exchange plate 402 during passing through the fixed frame 401, so that the heat exchange cooling effect is realized. The cooled air finally enters the fan for cooling and temperature reduction, and the heat-exchanged and heated water is discharged from the water outlet joint 406 and finally enters the cooling box 1 from the recovery pipe 7 for recycling.

[0023] Through the above implementation, the connecting structure 5 includes a connecting frame 501, a circular pipe 502, a connecting flange 503, a fixing screw 504 and a supporting assembly 505. The connecting frame 501 is connected with the heat exchange structure 4 through the fixing screw 504. The circular pipe 502 and the connecting flange 503 are fixedly connected, and the circular pipe 502 is connected to the connecting frame 501. The supporting assembly 505 is installed on the connecting frame 501. The supporting assembly 505 includes a fixed column 5051, a screw rod 5052, an abutting plate 5053 and a hexagonal block 5054. The fixed column 5051 is fixed to the connecting frame 501. The screw rod 5052 is fixedly connected with the abutting plate 5053, and is threadedly connected to the fixed column 5051. The hexagonal block 5054 is fixed to the position where the screw rod 5052 is connected with the abutting plate 5053.

[0024] When the heat exchange structure 4 is installed, the connecting frame 501 is installed to the air inlet end of the fan by using the connecting flange 503 on the circular pipe 502 and cooperating with the screw. Then the hexagonal block 5054 in the supporting assembly 505 is rotated by using a tool. The hexagonal block 5054 rotates and moves on the fixed column 5051 with the screw rod 5052 until the abutting plate 5053 abuts against the fan. At this time, the supporting assembly 505 provides a supporting effect to ensure the stability of the connecting frame 501. Then the heat exchange structure 4 is inserted into the connecting frame 501, and is fixed by using the fixing screw 504. After the heat exchange structure 4 is installed, the pipeline is connected, and then the use is started.

[0025] It needs to be explained that through the heat exchange structure 4 and the connecting structure 5 set, the heat exchange structure 4 is connected to the fan air inlet end, and the external air is cooled by heat exchange in the process of entering the fan interior through the heat exchange structure 4, so that the air temperature entering the fan is low, the interior of the fan can be directly cooled and cooled, the cooling effect is improved, the wave heat exchange plate 402 is adopted, the contact area during air heat exchange is improved, the cooling strength for air can be increased, the cooling effect for the fan is further guaranteed, the heat exchange structure 4 is installed and dismounted through the connecting structure 5, the heat exchange structure 4 can be quickly dismounted and mounted, the operation convenience is high, the support assembly 505 is adopted, after the connecting structure 5 is connected with the fan air inlet end, the screw rod 5052 can be rotated to make the abutting plate 5053 contact the fan, the support effect can be provided, and the stability after the connecting structure 5 and the heat exchange structure 4 are installed is increased.
