[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.
[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 The embodiment of the fan wall of the present invention is shown, which includes a box body 10 and a fan 20 installed in the box body 10, and an air outlet corresponding to the fan 20 is opened on the box body 10, characterized in that the box body 10 is provided with an inspection door 11 that can be opened toward the inside of the box body 10. The fan wall also includes a moving mechanism 30 and a controller. Among them, the moving mechanism 30 is arranged at a position adjacent to the inspection door 11 in the box body 10, and the fan 20 includes a first fan 21 that will interfere with the opening of the inspection door, and the first fan 21 is installed on the moving mechanism. The controller is connected to the moving mechanism 30 by driving. Before the inspection door 11 is opened, the controller controls the moving mechanism 30 to move the first fan 21 to a position that does not affect the opening of the inspection door 11; after the inspection door 11 is closed, the controller controls the moving mechanism 30 to move the first fan 21 to the position of the corresponding air outlet.
[0025] By applying the technical solution of the present invention, the fan wall can be miniaturized and the gap between the box 10 and the fan 20 can be minimized. Even if the use position of the first fan 21 will interfere with the opening of the maintenance door 11, the movement of the first fan 21 can be controlled by the controller and the moving mechanism 30 to avoid the first fan 21 interfering with the opening of the maintenance door 11.
[0026] Preferably, in the technical solution of this embodiment, Figure 3 As shown, the moving mechanism 30 includes a guide rail 31 and a moving seat 32. The guide rail 31 is installed in the box body 10, the moving seat 32 is installed on the guide rail 31, the first fan 21 is installed on the moving seat 32, and the controller is electrically connected to the moving seat 32 to control the movement of the moving seat 32. As other optional embodiments, the moving mechanism 30 can also be implemented by other mechanical structures.
[0027] like Figure 3 As shown, in the technical solution of this embodiment, the guide rail 31 extends from the access door 11 to a position away from the access door 11. By moving the first fan 21 away from the access door 11, the effect of preventing the first fan 21 from interfering with the opening of the access door 11 can be achieved. As an optional implementation, Figure 4 and Figure 5 As shown, the guide rail 31 is arranged in the horizontal direction. As other optional embodiments, Figure 3 As shown, the guide rail 31 can also be arranged in the horizontal direction and in the vertical direction at the same time. In this embodiment, the first fan 21 can be moved horizontally to a position away from the inspection door 11, and can also be moved vertically to a position away from the inspection door 11.
[0028] like Figure 4 and Figure 5 As shown, there are multiple fans 20, including a first fan 21 and a second fan 22 adjacent to the first fan 21, and there are multiple movable seats 32, and the first fan 21 and the second fan 22 are respectively arranged on the multiple movable seats 32. When in use, before the access door 11 is opened, the first fan 21 and the second fan 22 move together to a position that does not affect the opening of the access door 11; after the access door 11 is closed, the first fan 21 and the second fan 22 move to the positions of their respective corresponding air outlets.
[0029] As an optional embodiment, the mobile seat 32 includes a seat body and a track wheel installed at the bottom of the seat body, and the track wheel is installed and matched with the guide rail 31. More preferably, the track wheel can be hidden in the seat body through a protruding mechanism. In this way, when not in use, the track wheel can be hidden and the seat body can be matched with the guide rail 31.
[0030] More preferably, a position corresponding to the air outlet is provided on the guide rail 31, and the seat body is stuck in the position before the track wheel extends out of the seat body, and the seat body is disengaged from the position after the track wheel extends out of the seat body, and the track wheel drives the seat body to move on the guide rail 31. The position on the guide rail 31 can make the fan 20 more stably positioned when in use.
[0031] As a preferred embodiment, the inspection door 11 is provided with a door switch 12, and the controller is installed on the door switch 12. When the door switch 12 is turned on, the controller controls the moving mechanism 30 to move the first fan 21 to a position that does not affect the opening of the inspection door 11; when the door switch 12 is turned off, the controller controls the moving mechanism 30 to move the first fan 21 to the position of the corresponding air outlet.
[0032] Preferably, in the technical solution of this embodiment, the above-mentioned fan 20 is an EC fan.
[0033] Specifically, when the technical solution of this embodiment is used, a certain space distance must be ensured between EC fans. If the distance is too small, mutual interference will lead to air volume loss and increased noise. Therefore, the fan center distance must be ≥1.7D, where D is the diameter of the fan. The inspection door needs to be operated twice before it can be truly opened. The first time is to release the pressure, twist the door switch 12 from the vertical direction to the horizontal direction, so that the atmospheric pressure inside the unit is consistent with the atmospheric pressure of the external environment to ensure the safety of the maintenance personnel. The second time is to twist the door switch 12 from the horizontal direction to the vertical direction, and the inspection door can be truly opened. When the door switch 12 is twisted for the first time, the controller is started, the EC fan is pushed out from the card position, and the adjustable angle track wheel hidden in the EC fan section extends out, the track wheel is sent to the track, and slides along the guide rail. There is a section of guide rail between each card position, which can ensure that the fan moves to any card position. The track wheel on the EC fan can move the fan vertically or horizontally. After the EC fan moves to a certain position, the inspection door can be opened to avoid the interference problem between the inspection door and the EC fan. When the inspection door is completely closed, the EC fan returns to its original position to ensure the uniformity of the EC fan's wind field.
[0034] The layout of the fan wall can be adjusted as needed to improve the uniformity of the wind field and the heat exchange performance. At the same time, the number of EC fans can be increased or decreased. In addition, when repairing the fan, start the device and move the fan downward for easy disassembly. There is no need to move the ladder, which reduces the risk, reduces labor, and saves time costs.
[0035] The present invention also provides an air conditioning unit, which includes the above-mentioned fan wall. The air conditioning unit using the above-mentioned fan wall is conducive to miniaturization and maintenance.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the embodiments of the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
