[0022] Among them, the refrigerator 16 and the water tank 17 are fixedly connected to the inner wall of the cooling box 3, the output end of the water tank 17 and the input end of the refrigerator 16 are connected through a connecting pipe 18, and the output end of the refrigerator 16 and the input end of the water tank 17 are connected through a cooling pipe 13, and the cooling pipe 13 is distributed in a serpentine line.

[0023] A plurality of support plates 14 are provided at the bottom of the cooling tube 13 , and both ends of the support plates 14 are fixedly connected to the inner wall of the cooling box 3 .

[0024] The cooling pipe 13 can be supported by the provided support plate 14 .

[0025] A guide plate 15 is fixedly mounted on the upper end of the air intake plate 10 . The guide plate 15 is located at the edge of the inner frame of the air intake plate 10 . The height of the guide plate 15 is less than the height of the inner cavity of the cooling box 3 .

[0026] With this arrangement, a guide channel can be formed between the air intake plate 10 and the inner wall of the cooling box 3, ensuring that the air entering the cooling box 3 from the outside can move directly to the top of the inner cavity of the cooling box 3, thereby ensuring that the air entering the cooling box 3 can come into contact with the cooling pipe 13.

[0027] A fixing frame 11 is fixedly installed at the bottom of the air intake plate 10 , and a screen 12 is provided at the bottom opening of the fixing frame 11 .

[0033] The utility model provides a digital controlled DC power supply cabinet, the specific working principle of which is as follows:

[0034] When in use, start the heat dissipation fan 8, the heat dissipation fan 8 will draw the hot air inside the power supply body 4 out through the air holes at the bottom of the power supply body 4, and discharge it to the outside of the cabinet 1 through the heat dissipation holes 6. After the hot air in the power supply body 4 is drawn out, the power supply body 4 is under negative pressure. At this time, the outside air will enter the interior of the power supply body 4 through the air holes at the upper end of the power supply body 4, and the outside air will first enter the cooling box 3 for cooling before entering the power supply body 4. Specifically, the built-in water pump of the refrigerator 16 will control the cooling water to circulate between the refrigerator 16, the cooling pipe 13, the water tank 17 and the connecting pipe 18. When the outside air enters the interior of the cooling box 3 from the bottom of the air intake plate 10, it will be cooled by the cooling pipe 13, thereby ensuring that the air entering the power supply body 4 is cool air, thereby effectively cooling the interior of the power supply body 4. The air intake plate 10 is arranged at the bottom of the cooling box 3, which can effectively prevent external dust from falling directly on the air intake plate 10 during daily use, thereby preventing the air intake plate 10 from being blocked.
