[0052] A plurality of cold air outlets are provided through the top of the cold air sub-duct 21 so that the heat of the first device 5, the second device 6 and the third device 7, that is, all the power distribution equipment installed in the power facility body 1, can be removed by the air blown out from the cold air outlets through the cold air outlets and the cold air sub-duct 21.

[0053] The type of the cold air driving member 23 is a fan, which is fixedly installed outside the power facility body 1, and the input end of the cold air output main pipe is connected to the cold air driving member 23, so that the air outside the power facility body 1 is forced to be transported to the cold air sub-pipe 21 through the fan blades of the cold air driving member 23, so that the air with lower temperature enters the inside of the power facility body 1. In addition, an air inlet grille filter 231 is fixedly installed at the air inlet of the cold air driving member 23, so as to prevent debris, insects and animals from entering the cold air driving member 23, thereby helping to reduce the blockage of the cold air driving member 23, the cold air main pipe 22 and / or the cold air sub-pipe 21.

[0054] Reference Figure 4 and Figure 6 The independent cooling component 3 includes an independent air duct 31 and an independent driving member 32.

The independent air duct 31 is located on the side of the power distribution equipment. In the present application, the side of the power distribution equipment refers to: the front, back, left and right directions of the power distribution equipment. A plurality of independent air vents are provided through the side of the independent air duct 31 toward the third device 7, so as to facilitate the delivery of sufficient amount of low-temperature air to the third device 7 with a larger heat generation through the independent air vents. The type of the independent driving member 32 is a fan, and the independent driving member 32 is fixedly mounted on the outside of the power facility body 1, and an independent grille 321 is fixedly mounted on the air inlet of the independent driving member 32. The independent driving component 32 is installed on the input end of the independent air duct 31 and is connected to the independent driving component 32, so that the air outside the power facility body 1 is forced to be transported into the independent air duct 31 through the fan blades of the independent driving component 32, so that the air with lower temperature enters the interior of the power facility body 1 and dissipates the heat of the third equipment 7 with higher temperature.

[0055] Reference Figure 4 and Figure 7 The hot air delivery assembly 4 is located at the top of the power facility body 1, and the hot air delivery assembly 4 includes a hot air sub-tube 41, a hot air main tube 42, and a hot air driving member 43. There are a plurality of hot air sub-tubes 41, and specifically in the embodiment 1 of the present application, the number of the hot air sub-tubes 41 is set to four. The four hot air sub-tubes 41 are all connected to the output end of the hot air main tube 42, and the four hot air sub-tubes 41 are distributed along the length direction of the hot air main tube 42.

[0056] The four hot air sub-tubes 41 are all located on the top of the power distribution equipment, and the four hot air sub-tubes 41 are all fixedly installed on the roof inside the power facility body 1. Two of the hot air sub-tubes 41 are located on both sides of the first device 5, and the other two hot air sub-tubes 41 are located on both sides of the second device 6 and the third device 7, and the four hot air sub-tubes 41 are respectively located on the top of the four cold air sub-tubes 21. A plurality of hot air outlets are provided through the top of the hot air sub-tubes 41, so that the air at the top of the power facility body 1 can be transported to the outside of the power facility body 1 through the hot air outlets and the hot air sub-tubes 41.

[0057] The hot air drive 43 is a fan, which is fixedly mounted on the outside of the power facility body 1 and is arranged away from the cold air drive 23. The input end of the hot air output main pipe is connected to the hot air drive 43, so that the air inside the power facility body 1 is forced to be transported to the hot air sub-pipe 41 through the fan blades of the hot air drive 43, so that the air with a higher temperature that has absorbed the power distribution equipment is transported to the outside of the power facility body 1. In addition, an air outlet grille filter 431 is fixedly mounted on the air inlet of the hot air drive 43 to prevent debris, insects, animals, etc. from entering the hot air drive 43, thereby helping to reduce the occurrence of blockage of the hot air drive 43, the hot air main pipe 42 and / or the hot air sub-pipe 41.

[0058] The implementation principle of an automatic cooling device for an equipment room in Example 1 of the present application is as follows: the cold air sub-duct 21, the cold air main pipe 22 and the cold air driving component 23 force the external air with a lower temperature to be transported to the interior of the power facility body 1, so that there is always enough air inside the power facility body 1 as a medium for transporting the heat of the distribution equipment, thereby transferring the heat from the distribution equipment in a timely manner.

[0059] After the air absorbs the heat from the first device 5, the second device 6 and / or the third device 7, the temperature rises, and the density of the air after the temperature rises decreases, and the air moves toward the top of the power facility body 1. The hot air sub-pipe 41, the hot air main pipe 42 and the hot air driving member 43 force the air at the top of the power facility body 1 to the outside of the power facility body 1, so that there is always air entering and leaving the power facility body 1, and the heat generated by the first device 5, the second device 6 and the third device 7 during operation is taken away by the air in time, thereby fully meeting the heat dissipation requirements of the power distribution equipment inside the power facility.

[0060] In addition, for the third device 7 with a large heat generation, on the basis of the cold air sub-duct 21, the cold air main 22 and the cold air driving component 23, the heat dissipation effect is further enhanced through the independent air duct 31 and the independent driving component 32, so that the automatic cooling device of the equipment room can further meet the heat dissipation needs of the third device 7 with a large heat generation.
