[0002] At present, the working faces of most mines in my country are below one kilometer, and the ambient temperature caused by geothermal heat is relatively high. Therefore, cooling technology is increasingly widely used in mine safety production. At present, most of the artificial cooling systems in mines are aimed at reducing the overall temperature of the working space in the mine. Therefore, large refrigeration and transportation equipment are required to provide cooling capacity, and the cooled cold air is simply sent to the air supply tunnel of the working face. Since the cold air supply position is still a certain distance away from the working face with high temperature and humidity, this part of the wind has been fully mixed with the surrounding ambient air before entering the working face. Therefore, the wind temperature delivered to the employees' work stations is not low, and the humidity of the surrounding air does not change much. The dehumidification and cooling effects are not obvious, and the employees' requirements for comfort cannot be met. In addition, the entire system is complex, requires many auxiliary equipment, and consumes high energy during operation.

The axis position of the shell 13-1 passes through and rotates with a T-tube 13-3 with one end sealed, and the other end of the T-tube 13-3 is provided with a plurality of exhaust ports 13-5, and the T-tube 13-3 located in the shell 13-1 is provided with a plurality of fan blades 13-4, and the T-tube 13-3 located in the shell 13-1 is also provided with a plurality of air flow inlets; the semiconductor refrigerator 3 and the air pump 11 are both electrically connected to the control module 24 arranged on the box body 1.

[0016] Based on the above, the heat dissipation pipe includes a plurality of downward bending parts and the downward bending parts are provided with a downward extending drainage pipe 5, the drainage pipe 5 extends into the water collecting box 6 below the base frame 21, and a removable sealing plug is provided at the lower end of the drainage pipe 5.

[0017] The dust collecting device 8 is used to collect dust in the air flow entering the air inlet pipe 9, and includes a separation box 8-1. A slag discharge port is provided at the bottom of the separation box 8-1, and a sealing cover is provided at the slag discharge port. An air outlet is provided at the top of the separation box 8-1. A partition 8-3 is provided inside the separation box 8-1, and a cyclone separator 8-4 is penetrated through the partition 8-3. The air outlet is connected to the air supply pipe 7, and the air inlet 13-2 of the cyclone separator 8-4 is connected to the air inlet pipe 9.

[0018] In order to prevent dust in the air flow from entering the heat exchange tube 4, a pull-out filter screen 8-2 is provided above the partition plate 8-3 in the separation box 8-1.

[0019] In order to facilitate the rapid discharge of heat generated by the semiconductor refrigerator 3, a rotating rod 19 is penetrated and rotatably provided on the above-mentioned box body 1.

The semiconductor refrigerator 3 cools the water in the water tank 2. When the air pump 11 is working, the high-temperature airflow enters the air inlet pipe 9 from the air inlet hole, and then the airflow enters the cyclone separator 8-4 in the dust collecting device 8 for dust removal. The air after dust removal is discharged. After passing through the filter 8-2 for purification again, it is discharged from the exhaust port 13-5 through the air supply pipe 1 7 and discharged into the heat exchange pipe 4 for heat exchange with low-temperature water. The moisture in the air flow condenses and enters the drain pipe 5. The dehumidified and cooled air flow enters the outer casing 13-1 through the air supply pipe 2 10, the air pump 11 and the air supply pipe 3 12. The air flow impacts the fan blades 13-4 and the T-tube 13-3 rotates. Then the air flow enters the T-tube 13-3 from the air flow inlet and is finally discharged from the exhaust port 13-5 to cool the surrounding area.

[0021] In addition, when the T-tube 13 - 3 rotates, the rotating rod 19 is driven to rotate, and then the fan blades 20 are rotated, so that the external cold air flow enters the box body 1 and sends the heat generated by the semiconductor refrigerator 3 out from the exhaust port 16 .

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
