The electrical cabinet is a cabinet used to carry the control module in the electrical automation control system. The electrical cabinet is made of steel to protect the normal operation of components. The manufacturing materials are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0044] First, various electrical components are installed on different partition plates 106 and the sealing door 102 is closed. Then the power is turned on. The electrical components work and generate heat in different areas and time periods. Then the intelligent control module 110 controls the air supply fan 109 to operate. After that, the external air passes through the air intake net 103, the dust removal and drying component 108, the air perforated plate 107, and the air supply fan 109 driven by the air supply fan 109 to enter the cavity on the right side of the right vertical plate 104 inside the electrical cabinet housing 101. Then the airflow passes through the rectangular tube 30, the rectangular ring 31, the docking hole 34, the diversion circular tube 40, the diversion flow hole 45, and the diversion fixed hole 42 to blow to the area where the electrical components are installed above the partition plate 106. Then the airflow absorbs heat to cool the electrical components. The rear temperature sensor 111 detects the temperature of the airflow in real time and sends the temperature data to the intelligent control module 110, and then the intelligent control module 110 analyzes the temperature data and determines the highest temperature area according to the position of the temperature sensor 111. Each temperature measurement area is positioned by a corresponding positioning probe 112. Then the intelligent control module 110 controls the operation of the diversion servo motor 43 according to the temperature value. After that, the diversion servo motor 43 rotates with the diversion flow disc 44 through the transmission rod 47, the transmission slide groove 48, and the moving slide 49, and then the diversion flow disc 44 rotates with the diversion flow hole 45, thereby changing the size of the docking area between the diversion fixed hole 42 and the diversion flow hole 45, and then changing the size of the airflow flow channel, and finally achieving the purpose that the airflow size is proportional to the temperature. That is, the area where the diverter flow disk 44 and the diverter flow hole 45 corresponding to the high temperature area are connected is larger than the area where the diverter flow disk 44 and the diverter flow hole 45 corresponding to the low temperature area are connected. Then the intelligent control module 110 controls the push servo motor 51 to operate, and then the push servo motor 51 rotates with the push threaded rod 52, and then the direct input block 61 gradually approaches the highest temperature area under the action of the threaded cooperation between it and the push threaded rod 52. When the highest temperature area is located above the direct input block 61, the direct input block 61 moves upward with the flow channel control mechanism 7, and then the triangular connector 76 moves vertically upward relative to the plug hole 57. At this time, the ends of two force-bearing rods 28 slide on the right side of the U-shaped force strip 78, and then the inner wall of the plug hole 57 presses against the triangular connector 76. The thrust is applied, and then the triangular connector 76 moves toward the inside of the rectangular cavity 71 and moves to the left with the U-shaped force strip 78 by opening the piston plate 75 and the linkage slide 77. Then the end of the force rod 28 at the bottom end of the U-shaped force strip 78 slips off the surface of the U-shaped force strip 78. Then the air-blocking plate 22 moves to the left under the elastic tension of the return spring 27. The air-blocking plate 22 moves to the left with the force rod 28, and then the air-blocking hole 24 is staggered with the conducting hole 23. Then the air-blocking plate 22 moves to the left with the moving rod 25, and then the traction line 37 is relaxed. Then the strip slider 32, under the elastic force of the positioning slider 35, moves the separating slider 33 away from the inner wall of the rectangular tube 30, and then the conducting hole 23 corresponding to the slipped force rod 28 is completely staggered with the air-blocking hole 24.Then, the docking holes 34 on the two separated slide plates 33 below the slip-off force-bearing rod 28 are docked and completely connected, and at the same time, the docking holes 34 on the two separated slide plates 33 above the slip-off force-bearing rod 28 are partially staggered, and then the tip of the triangular connector 76 slides to the left side surface of the left vertical plate 105, at this time, the U-shaped force strip 78 is separated from the end of the other force-bearing rod 28, and the corresponding partially staggered docking holes 34 are completely docked and connected, and then the triangular connector 76 moves upward and gradually aligns with the corresponding plug hole 57, at this time, the force-bearing rod 28 at the top of this plug hole 57 corresponds to the U-shaped force strip 78, and then the piston plate 75 is opened and moves into the plug hole 57 with the triangular connector 76 under the action of the elastic force of the opening spring 74, and then the piston plate 75 is opened. The U-shaped force-applying bar 78 is moved toward the left vertical plate 105 through the linkage slide 77, and then the U-shaped force-applying bar 78 applies a rightward thrust to the two force-bearing rods 28 on the upper and lower sides of the plug-in hole 57, and then the force-bearing rod 28 pushes the air-blocking plate 22 to move to the right, and then the conducting holes 23 corresponding to the two force-bearing rods 28 are connected with the air-blocking hole 24, and at the same time, the two force-bearing rods 28 apply a pulling force to the corresponding traction line 37 through the air-blocking plate 22 and the moving rod 25, and then the two traction lines 37 between the two force-bearing rods 28 are simultaneously subjected to a pulling force, that is, the flow-breaking mechanism 3 is subjected to force on both sides, and then the two strip sliders 32 in the position between the two force-bearing rods 28 respectively bring the separating slides 33 close to the inner wall of the rectangular tube 30, and then the two separating slides 33 are opposite to each other. The connecting holes 34 are completely connected and connected, thus ensuring that the interrupting mechanism 3 directly corresponding to the high-temperature airflow direct transmission mechanism 6 is in a conducting state. At the same time, the two interrupting mechanisms 3 in the direction in which the two force-bearing rods 28 are away from each other are both stressed by a traction line 37, that is, they are unilaterally stressed. Then the stressed traction line 37 pulls the separating slide plate 33 and the connecting hole 34 close to the inner wall of the rectangular tube 30 through the corresponding strip slider 32, and the other separating slide plate 33 is fixed with the connecting hole 34, so that the connecting holes 34 on the two separating slide plates 33 are completely staggered, that is, the interrupting mechanism 3 with unilateral force is in a disconnected state and has no ability to ventilate air. In this way, the high-temperature airflow direct transmission mechanism 6 directly corresponds to the interrupting mechanism 3 on the upper and lower sides of the interrupting mechanism 3 in a disconnected state, avoiding the formation of airflow collision, such as Repeat the above actions until the high-temperature airflow direct delivery mechanism 6 is directly aimed at the highest temperature area, and then the airflow passes through the corresponding rectangular tube 30, rectangular ring 31, docking hole 34, diversion circular tube 40, diversion flow hole 45, and diversion fixed hole 42 to blow directly to the highest temperature area, and at the same time, the airflow passes through the corresponding rectangular tube 30, rectangular ring 31, docking hole 34, diversion circular tube 40, diversion flow hole 45, and diversion fixed hole 42 to blow directly to other areas except the upper and lower adjacent areas of the highest temperature area, and then the airflow in these areas passes through the vent hole 56 and the plug hole 57 to enter the cavity on the left side of the left vertical plate 105 inside the electrical cabinet housing 101 and passes through the corresponding vent hole 56 and the plug hole 57 to enter the upper and lower adjacent areas of the highest temperature area and cool down the internal components.Then the airflow in the upper and lower adjacent areas of the highest temperature area passes through the closed air holes 24 and the conducting holes 23 to enter the highest temperature area. The airflow further absorbs heat in the highest temperature area and increases the airflow velocity inside it, increasing the heat dissipation rate of the highest temperature area. After that, the high-temperature airflow passes through the corresponding vent holes 56, the direct delivery holes 62, the direct delivery flat holes 63, the high-elastic bellows 54, the annular channel between the cavity strip 53 and the push threaded rod 52, and the exhaust hole 55 to be discharged, thereby achieving the purpose of targeted rapid cooling.
