Dust and moisture will have an adverse effect on electrical instruments. Traditional electrical cabinet heat dissipation systems are usually fans with filters to filter the air, and the moisture in the air is absorbed by desiccants. This mode can be used in stable environments, but during rainy or windy seasons, its control over dust and moisture becomes unstable.

The air outlet of heat dissipation pipe 5410 is connected to one side of two ventilation boxes 467 through a three-way pipe. The other side of ventilation box 467 is fixedly connected to exhaust pipe 5412, and the air outlet of exhaust pipe 5412 is located outside the cabinet 1. The bottom end of the side wall of air intake box 541 is fixedly connected to drain pipe 5411, and the water outlet of drain pipe 5411 extends to the outside of cabinet 1.

[0025] The air handling unit 54 also includes a heat exchange box 5413, which is installed on the inner wall of the cabinet 1. The middle section of the air supply pipe 544 is bent and located inside the heat exchange box 5413, and the middle section of the air intake pipe 42 is bent and located inside the heat exchange box 5413. The heat exchange box 5413 is filled with heat exchange fluid, which can be water, coolant, or other liquids suitable for transferring heat.

[0026] A filter pipe 13 is installed near the air inlet of the air supply pipe 543. Activated carbon 14 is installed inside the filter pipe 13. Please refer to [link / reference]. Figure 3 The filter pipe 13 should be higher than the air inlet end of the air supply pipe 543. The porous structure of the activated carbon 14 can capture the fine water droplets that follow the airflow. The wastewater filtered by the activated carbon 14 can flow back into the air inlet box 541.

[0027] A vibration generator 15 is fixedly installed on the inner bottom wall of the air intake box 541. A vibration transmission pad 16 is installed on the outside of the vibration generator 15. The bottom end of the condenser plate 547 is inserted into the slot on the upper surface of the vibration transmission pad 16. The vibration of the vibration generator 15 transmitted to the condenser plate 547 through the vibration transmission pad 16 can agitate water droplets and help filter residual dust in the air. The vibration generator 15 can be a vibration motor or an ultrasonic generator.

[0028] A humidity sensor 17 is also installed inside the mounting hole 465. With the design of the humidity sensor 17, the threshold is set by the installer. When the humidity sensor 17 detects that the humidity of the moisture-absorbing strip 466 has reached the threshold, the drive motor 461 drives the rotating ring 464 to rotate and switch the position of the mounting hole 465, so that the dry moisture-absorbing strip 466 can be switched into the ventilation box 467 that needs to absorb moisture. A filter screen 18 is provided on the outer wall of the cabinet 1 at the position corresponding to the air inlet 542 for filtering dust from the outside air.

[0029] When this device is in operation, the electrical instruments are installed inside the mounting housing 41. The air compressor 52, vibration generator 15, semiconductor cooling chip 548, and radiator 549 operate, drawing air from outside the cabinet 1 through the air inlet 542. The outside air first passes through the filter screen 18 to filter dust. After entering the air intake box 541, the air passes through the condenser plate 547, where moisture forms water droplets. These water droplets are shaken off by the vibration generator 15 and fall to the bottom of the air intake box 541, exiting the cabinet through the drain pipe 5411. The air, after being condensed and dehumidified, passes through the activated carbon 14 in the filter pipe 13 and then enters the ventilation box 46. Moisture is absorbed by the moisture-absorbing strip 466 inside the 7. During the moisture absorption process, the humidity sensor 17 inside the moisture-absorbing strip 466 detects its humidity. When the humidity reaches the set value, the drive motor 461 works, driving the rotating ring 464 to rotate and switching the ventilation box 467 corresponding to each moisture-absorbing strip 466. The moisture-absorbing strip 466 in the middle is dried by the hot air blown out by the heat dissipation pipe 5410 and is ready for use. Then it is compressed into the compressed air cylinder 51 by the air compressor 52. When the air pressure in the compressed air cylinder 51 reaches the set value, the solenoid valve 12 on the pressure relief pipe 55 is opened, and the semiconductor cooling chip 548 and the heat sink 549 continue to work to deliver hot air to the heat dissipation pipe 5410. After the compressed gas cylinder 51 is filled with gas, the circulating air pump 45 starts working. The solenoid valves 12 on the inlet pipe 42 and the exhaust pipe 44 are opened, and the solenoid valve 12 on the circulating pipe 47 is closed. Air is drawn from above the partition 3 and discharged to the outside of the cabinet 1, so that the space above the partition 3 forms a negative pressure. After most of the air is drawn away, the solenoid valve 12 on the exhaust pipe 44 is closed, and the solenoid valves 12 on the circulating pipe 47 and the connecting pipe 53 are opened. The dry and clean air in the compressed gas cylinder 51 is replenished into the space above the partition 3 by the circulating air pump 45. After heat exchange with the electronic instruments, it enters the circulating air pump 45 through the inlet pipe 42 to complete the circulation. During this process, the hot air in the inlet pipe 42 in the heat exchange box 5413 exchanges heat with the cold air in the supply pipe 544 through the heat exchange liquid to form low-temperature air before entering the space above the partition 3. The air in the supply pipe 544 is cooled by the condenser plate 547.

[0030] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
