[0021] As Figure 1 shown, a POE-powered network switch includes a casing 1 and ventilation components 2 provided on both sides inside the casing. The ventilation components 2 are used to discharge the hot air inside the switch; it also includes an induction component 3 provided inside the casing 1. The induction component 3 is used to sense and control the heat inside the casing 1. Air inlets 4 are provided at both ends of the casing 1, and an exhaust port 5 is provided at the bottom end of the casing 1.

[0022] like Figures 2-3 -4, the ventilation assembly 2 includes a partition 6 and an annular shell 7. The partition 6 is fixed to the inside of the casing 1. The partition 6 and the annular shell 7 form a closed dehumidification chamber 8. The annular shell 7 is fixed to the upper end of the exhaust port 5. A filter plate 9 is provided on the upper end of the annular shell 7. A closed boost chamber 10 is formed inside the annular shell 7. A turbine air pump is provided on one side of the casing 1. The turbine air pump is connected to the boost chamber 10 through a conduit to achieve controllable ventilation effect.

[0023] like Figures 2-3 As shown, the sensing component 3 includes a thermistor 11 and a microprocessor 12. A closed working chamber 13 is formed between the partitions 6. The thermistor 11 is fixed to the top of the working chamber 13. The microprocessor 12 is fixed inside the working chamber 13. A through hole 14 is provided between the working chamber 13 and the dehumidification chamber 8 to realize heat sensing and automatic control.

[0024] Among them, the air inlet 4 is arranged at both ends of the casing 1, the air inlet 4 is connected to the dehumidification chamber 8, the exhaust port 5 is arranged at the bottom end of the casing 1, the exhaust port 5 is connected to the working chamber 13, and a drain port 15 is provided at the bottom end of the dehumidification chamber 8. The dehumidification chamber 8 is filled with silica gel adsorbent, the thermistor 11 is connected to the microprocessor 12 through a wire, and the microprocessor 12 is connected to the turbine air pump through a wire.

[0025] During specific use, when a large amount of heat is generated in the working chamber 13, the resistance of the thermistor 11 decreases as the temperature rises, and the current in the circuit increases. The microprocessor 12 senses the current change in the circuit, and the microprocessor 12 closes the circuit of the turbo air pump. The turbo air pump draws the gas into the pressurized boost chamber 10, and then guides the pressurized gas out of the lower end of the exhaust port 5. The airflow at the lower end of the exhaust port 5 is accelerated, and the pressure at the lower end of the exhaust port 5 is lower than the pressure in the working chamber 13. Due to the pressure difference, the gas in the working chamber 13 is drawn out, and then the gas is drawn into the dehumidification chamber 8 through the air inlet 4. The silica gel adsorbent in the dehumidification chamber 8 absorbs the moisture in the drawn gas, and then the water in the silica gel adsorbent is discharged through the drain port 15.
