It is usually used in communication, computer and other communication fields. Its main function is to centralize communication equipment and protect it.

[0003] At present, during the use of communication installation cabinets, dust is easily adhered to the surface of the dust removal net installed at the heat dissipation port of the cabinet, causing the dust removal net to be blocked, resulting in a reduction in the ventilation cross-sectional area of ​​the communication installation cabinet and a reduction in the air flow rate. As a result, during the operation of the communication cabinet, the heat inside the cabinet cannot be effectively and timely discharged, and the communication cabinet suffers from poor heat dissipation, which can easily cause the temperature inside the communication cabinet to rise abnormally, causing key components in the cabinet such as the motherboard and power module to overheat. This will not only cause the overall overload operation of the communication installation cabinet, but also easily cause damage to the communication equipment in the cabinet, affecting the stability of the overall operation of the communication installation cabinet. In severe cases, it may even cause a fire, posing certain safety hazards.

[0016] Beneficial effect: One or more technical solutions provided in the technical solution of the present invention have at least the following technical effects or advantages: 1. After dust adheres to the surface of the dust removal net and hinders the dissipation of heat inside the communication cabinet, the heat accumulated in the communication cabinet is continuously conducted to the thermosensitive medium part through the heat-inducing needle in the extended sensing structure. When the temperature inside the communication cabinet exceeds the preset critical upper limit, the thermosensitive medium part expands and deforms and drives the top kit to move, driving the annular trigger sheet in the opening and closing component to contact the trigger spring sheet and trigger the air source generating module to open. The air source generating module continuously inputs high-pressure airflow into the slit airway in the high-pressure forcing component through the air outlet hose, and the high-pressure airflow is then ejected from the outlet of the slit airway toward the dust removal net. The impact force generated by the high-pressure airflow can quickly spray away the dust adhered to the surface of the dust removal net, effectively restore the permeability of the mesh of the dust removal net, and allow the heat accumulated inside the communication cabinet to be quickly dissipated through the cleaned dust removal net.

[0017] 2. When the surface of the dust removal net is clean and the heat exchange is normal, the high-pressure forced component located inside the ventilation hood will not affect the normal circulation of the airflow inside the ventilation hood, and can adhere to dust on the surface of the dust removal net and affect the heat dissipation in the subsequent process, so that the thermal sensitive medium part expands and deforms and drives the top kit to move. It moves synchronously with the top kit and realizes scanning and spraying dust removal for the dust removal net, which helps to improve the cleaning coverage rate of the dust removal net and expand the cleaning area, so that more heat can be dissipated through the cleaned dust removal net per unit time, thereby ensuring the heat dissipation efficiency of the communication cabinet.

[0018] 3. After the air source generating module is turned on, the air source generating module continuously extracts the hot gas inside the communication cabinet through the air inlet pipeline, and then continuously inputs high-pressure airflow into the slit airway through the air outlet hose to spray away the dust adhering to the surface of the dust removal net. When the dust removal net is blocked and affects the normal heat dissipation inside the communication cabinet, it can realize autonomous forced dust cleaning and accelerate the discharge of the heat accumulated inside the communication cabinet, which helps to further improve the heat dissipation efficiency of the communication cabinet and ensure the stability and safety of the overall operation of the communication installation cabinet.

[0019] 4. When the internal temperature of the communication cabinet drops below the preset critical upper limit, the thermosensitive medium part is cooled and the volume gradually shrinks. Under the elastic pressure of the reset spring, the top kit retracts toward the inner cavity of the insulating and heat-insulating cylinder shell again. After the top kit returns to its initial state, the annular trigger piece and the trigger spring in the opening and closing assembly separate from each other again, and the air suction pump is turned from the open state to the closed state, avoiding the energy waste caused by the continuous operation of the air source generation module after the scanning spray dust removal of the dust removal net is realized, thereby helping to reduce the power consumption during the operation of the communication cabinet.

The top sliding sleeve of the heat-introducing needle 216 is provided with a top sleeve that slides in the heat-insulating cylinder in a sealed manner up and down. The heat-insulating cylinder is also filled with a thermosensitive medium part 215 located below the top sleeve. The top sleeve includes an inverted U-shaped traction frame 205 connected to a high-voltage forcing member, wherein the thermosensitive medium part 215 is made of paraffin material, and the phase change temperature of the paraffin material is: 45°C-55°C; The air source generating module includes an opening and closing component and an air suction pump 203.

[0035] After dust adheres to the surface of the dust removal net 202 and hinders the dissipation of heat inside the communication cabinet body 100, the heat accumulated in the communication cabinet body 100 is continuously conducted to the thermosensitive medium part 215 through the heat-inducing needle 216 in the extended sensing structure.

When the top assembly is driven by the expanded heat-sensitive medium part 215, the flexible waterproof breathable membrane cover 208 gradually changes from a folded and contracted state to an extended state.

[0040] When the heat-sensitive medium portion 215 expands in volume due to heat, the passive ring plug 214 in the top sleeve drives the top sleeve to move upward.

When the annular trigger piece 224 approaches the trigger spring piece 221 and contacts the trigger spring piece 221, the air suction pump 203 is triggered to start.

[0043] When the internal temperature of the communication cabinet body 100 drops below the preset critical upper limit, the thermosensitive medium part 215 is cooled and its volume gradually shrinks. Under the elastic pressure of the reset spring 217, the top kit retracts toward the inner cavity of the insulating and heat-insulating cylinder shell 213 again. After the top kit returns to its initial state again, the annular trigger piece 224 and the trigger spring 221 in the opening and closing assembly are separated from each other again, and the air pump 203 is turned from the open state to the closed state, avoiding the energy waste caused by the continuous operation of the air source generating module after the scanning spray dust removal of the dust removal net 202 is realized, thereby helping to reduce the power consumption during the operation of the communication cabinet.
