[0019] As shown in Figure 1 , Figure 2 , Figure 3 An embodiment of the present application provides a power distribution cabinet dehumidifying device, which comprises a power distribution cabinet body 1, a U-shaped pipe 2, an L-shaped pipe 3, a first fan 4, a second fan 5, a dehumidifying tank 6, the U-shaped pipe 2 is installed at the lower part of one side of the power distribution cabinet body 1, the L-shaped pipe 3 is installed at the upper part of the other side of the power distribution cabinet body 1, the U-shaped pipe 2 and the L-shaped pipe 3 both pass through the side wall of the power distribution cabinet body 1 and extend into the inner cavity of the power distribution cabinet body 1; the first fan 4 is installed on the inner side of the power distribution cabinet body 1 through the U-shaped pipe 2, and the second fan 5 is installed on the inner side of the power distribution cabinet body 1 through the L-shaped pipe 3; the outer end of the U-shaped pipe 2 and the L-shaped pipe 3 is provided with a threaded interface 7, the upper part of the dehumidifying tank 6 is connected with the threaded interface 7 through threads, and the dehumidifying tank 6 is filled with silica gel dehumidifying particles 8.

[0020] Silica gel dehumidification particles are a common dehumidifier, and the principle of silica gel dehumidification is to use the numerous pores of silica gel itself to adsorb the moisture in the air, thereby achieving the purpose of dehumidification. Silica gel is a hydrophilic material with strong adsorption capacity, and its micropores are numerous, which can adsorb water, gas and organic molecules. The adsorption capacity of silica gel is related to its specific surface area, and the larger the specific surface area, the stronger the adsorption capacity. At room temperature, the adsorption capacity of silica gel for water is the largest, and it can absorb 30% to 40% of its own weight of water.

[0021] The electronic equipment is installed in the power cabinet body 1, and when cooling, the first fan 4 is in the suction mode and the second fan 5 is in the exhaust mode. The air enters the power cabinet body 1 from the U-shaped pipe 2 and is discharged from the L-shaped pipe 3. When the air passes through the U-shaped pipe 2, it will contact the silica gel dehumidification particles 8 in the dehumidification tank 6 on the U-shaped pipe 2, thereby absorbing the moisture in the air through the silica gel dehumidification particles 8, maintaining the humidity in the power cabinet body 1 and ensuring the operation of the electronic equipment in the power cabinet body 1. After the air enters the power cabinet body 1 and exchanges heat with the electronic equipment, it is then discharged from the L-shaped pipe 3 and contacts the silica gel dehumidification particles 8 in the dehumidification tank 6 in the L-shaped pipe 3, thereby heating the silica gel dehumidification particles 8 and restoring the dehumidification capacity of the silica gel dehumidification particles 8 in the dehumidification tank 6.

[0022] After the dehumidification tank 6 in the U-shaped pipe 2 absorbs moisture for a period of time, the moisture absorption capacity gradually decreases. At this time, the operation direction of the first fan 4 and the second fan 5 is changed, so that the first fan 4 is in the exhaust mode and the second fan 5 is in the suction mode. The air passes through the L-shaped pipe 3 and enters the power cabinet body 1, and is then discharged from the U-shaped pipe 2, thereby using the dehumidification tank 6 on the L-shaped pipe 3 to absorb the moisture in the air and continue to maintain the humidity in the power cabinet body 1. Through the alternate use of the dehumidification tanks 6, one dehumidification tank 6 absorbs moisture and the other dehumidification tank 6 restores the moisture absorption capacity through hot air, thereby maintaining the moisture absorption capacity of the dehumidification tank 6 and ensuring the normal operation of the electronic equipment in the power cabinet body 1.

[0023] In a preferred embodiment, the dehumidification tank 6 is provided with a filter screen 9 at the upper and lower parts, and the silica gel dehumidification particles 8 are filled between the filter screens 9. The filter screens 9 hold the silica gel dehumidification particles 8 to prevent them from falling off.

[0024] In a specific embodiment, as shown in Figure 2 , Figure 3 the air outlet of the dehumidification tank 6 is downward, and the lower end surface of the lowermost filter screen 9 is spaced 5 to 10 cm from the lower end of the dehumidification tank 6. This can prevent raindrops from entering the dehumidification tank 6 on rainy days and ensure the normal dehumidification of the dehumidification tank 6. Since the air outlet of the dehumidification tank 6 is downward, in order to reduce the space occupied by the first fan 4 and the second fan 5 in the power cabinet body 1, the first fan 4 is arranged in a vertical state and the second fan 5 is arranged in a horizontal state.

[0025] Specifically, as shown in Figure 2 , Figure 3 , the U-shaped tube 2 and L-shaped tube 3 are provided with electric heaters 10, when the heat generated by the electronic equipment is insufficient to restore the silica gel dehumidification particles 8 to the moisture absorption capacity, the electric heater 10 can be started to heat the air, so that the silica gel dehumidification particles 8 in the dehumidification tank 6 restore the moisture absorption capacity.

[0026] Specifically, as shown in Figure 2 , Figure 3 , the power distribution cabinet body 1 is provided with a fixing frame 11, and the dehumidification tank 6 is connected with the threaded interface 7 after passing through the fixing frame 11 to ensure the stability of the dehumidification tank 6.

[0027] Preferably, the first fan 4 and the second fan 5 are both bidirectional axial flow fans, and the rotation direction of the impeller of the first fan 4 and the second fan 5 can be controlled by the controller, so as to adjust the air outlet direction of the fan, and further change the direction of the air flow entering the power distribution cabinet body 1.

[0028] Of course, the present application can also have other various embodiments, and based on the present embodiment, other embodiments obtained by those skilled in the art without any creative labor fall within the scope of the present application.
