Description

Technical Field

[0001] This utility model belongs to the technical field of EC fan exhaust boxes, specifically relating to a multi-point supply and exhaust box. Background Technology

[0002] EC smart fans, or electrically controlled fans, are ventilation devices driven by DC brushless fans. They boast significant advantages such as high intelligence, high energy efficiency, high performance, and long lifespan. EC fans utilize electronic commutation technology, with an electronic controller precisely controlling the fan's speed and power to achieve high-efficiency operation. The fan itself is a maintenance-free DC brushless fan with a built-in intelligent control module, offering excellent control performance. Compared to traditional fans, EC fans exhibit superior energy efficiency, converting electrical energy more efficiently and reducing energy loss. Furthermore, due to their optimized fan design and electronic commutation technology, EC fans generate relatively low noise during operation. They require less maintenance, reducing maintenance costs and extending the equipment's lifespan. Their outstanding performance in practical applications has led to their widespread use in various locations requiring ventilation.

[0003] However, the maximum air volume of existing single EC fans is often small, which is obviously insufficient when used for air supply / exhaust in data centers or large spaces. At this time, the reliability and rationality of the installation structure of multiple EC fans are particularly important. Therefore, a multi-point air supply and exhaust box is urgently needed to solve the above problems. Utility Model Content

[0004] To address the problems raised in the background section above, the objective of this utility model is to provide a multi-point supply and exhaust air box. To achieve this technical objective, the technical solution adopted by this utility model is as follows:

[0005] A multi-point supply and exhaust air box includes several fan boxes. Each fan box includes a base frame, with columns installed on the top four sides of the base frame. A top frame is installed on the top of each column. Baffles are installed inside both the base frame and the top frame. Air inlet windows, air outlet windows, side baffles, and door panels are installed between the four columns. A fan frame is also installed between the base frame and the top frame. Several EC fans are evenly installed on the fan frame.

[0006] Furthermore, the air inlet window, air outlet window, side baffle, and door panel are all connected and installed to the base frame and top frame on their upper and lower sides. The air inlet window is located on the front side of the base frame, the air outlet window is located on the rear side of the base frame, the side baffle is located on the inner side of the base frame, and the door panel is located on the outer side of the base frame. This structural design facilitates the installation and use of the air inlet window, air outlet window, side baffle, and door panel.

[0007] Furthermore, the air inlet window is an adjustable louver. This structural design allows the air inlet window to be closed when not in use, thus achieving a dust-proof effect.

[0008] Further specifying, the air outlet window includes a grid, and a sound-absorbing assembly is connected to the inner side of the grid. The sound-absorbing assembly includes an upper mounting plate and a lower mounting plate. The upper mounting plate is installed at the bottom of the top frame, and the lower mounting plate is installed at the top of the base frame. Several sound-absorbing plates are evenly installed between the upper and lower mounting plates, and an air outlet channel is formed between two adjacent sound-absorbing plates. This structural design achieves the effect of silent air outlet.

[0009] Furthermore, the door panel also includes a switch box door, one side of which is hinged to the door panel. A first latch is installed on the other side of the switch box door, and a first locking block is installed on the door panel corresponding to the first latch. Second latches are installed on the upper and lower sides of the switch box door, and second locking blocks are installed on the door panel corresponding to the second latches. This structural design facilitates the opening and closing of the switch box door by the operator.

[0010] The beneficial effects of this utility model are as follows: This utility model arranges and installs multiple EC fans in a wall-like manner inside the fan box, and assembles and connects multiple fan boxes to form a multi-point supply and exhaust air box, thereby forming a whole-area air supply with strong overall air delivery force. During use, when some EC fans fail, it will not affect the overall supply / exhaust air operation. Furthermore, through the coordinated assembly of multiple EC fans, the air volume is large, which meets the supply / exhaust air use in data centers or large spaces. Attached Figure Description

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multi-point supply and exhaust air box includes a fan box 1 comprising a base frame 2, columns 3 installed on the top four sides of the base frame 2, a top frame 4 installed on the top of the columns 3, baffles 5 installed inside the base frame 2 and the top frame 4, and air inlet windows 6, air outlet windows 7, side baffles 8 and door panels 9 installed between the four columns 3, and a fan frame 10 installed between the base frame 2 and the top frame 4, on which several EC fans 11 are evenly installed.

[0022] In this embodiment, during installation, multiple fan boxes 1 are assembled and connected to form a multi-point supply and exhaust air box, which is used for supply / exhaust ventilation in data centers or large spaces. During use, external air is drawn into the fan box 1 through the air inlet window 6 by the EC fans 11 on the fan frame 10 and discharged through the air outlet window 7. At the same time, the EC fans 11 are arranged in a wall-like manner, so that the air outlet window 7 forms a full-wall air supply, resulting in strong overall air delivery. During use, if some EC fans 11 fail, it will not affect the overall supply / exhaust ventilation operation. Furthermore, through the coordinated assembly of multiple EC fans 11, the air volume is large, which meets the supply / exhaust ventilation needs of data centers or large spaces.

[0023] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment adds the following structure based on embodiment 1: the air inlet window 6, the air outlet window 7, the side baffle 8 and the door panel 9 are all connected and installed to the base frame 2 and the top frame 4 on the upper and lower sides. The air inlet window 6 is located on the front side of the base frame 2, the air outlet window 7 is located on the rear side of the base frame 2, the side baffle 8 is located on the inner side of the base frame 2, and the door panel 9 is located on the outer side of the base frame 2.

[0024] In this embodiment, during installation, the air inlet window 6, air outlet window 7, side baffle 8 and door panel 9 are evenly installed between the base frame 2 and the top frame 4, making the overall layout reasonable and easy to install. Moreover, during use, the EC fans 11 arranged in a wall form a full-wall air supply at the air outlet window 7, ensuring the wind power effect and thus meeting the air supply / exhaust needs in data centers or large spaces.

[0025] Example 3, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: the air inlet window 6 is an adjustable louver.

[0026] In this embodiment, during use, the adjustable louvers are opened so that the EC fan 11 can draw external air into the fan box 1. When not in use, the air inlet window 6 is closed to achieve the effect of dust prevention.

[0027] Example 4, as Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the air outlet window 7 includes a grid 12, and a sound-absorbing group 13 is connected to the inner side of the grid 12. The sound-absorbing group 13 includes an upper mounting plate 14 and a lower mounting plate 15. The upper mounting plate 14 is installed at the bottom of the top frame 4, and the lower mounting plate 15 is installed at the top of the base frame 2. Several sound-absorbing plates 16 are evenly installed between the upper mounting plate 14 and the lower mounting plate 15, wherein an air outlet channel 17 is formed between two adjacent sound-absorbing plates 16.

[0028] In this embodiment, during use, the noise generated during exhaust is absorbed by the silencing plate 16 through the silencing group 13, thereby achieving the effect of noise reduction. This reduces the noise generated during airflow and finally discharges it from the grid 12. The grid 12 also serves as a dustproof device.

[0029] Example 5, as Figure 1 , Figure 5 and Figure 6As shown, this embodiment adds the following structure to embodiment 1: the door panel 9 is further provided with a switch box door 18. One side of the switch box door 18 is hinged to the door panel 9, and a first latch 19 is installed on the other side of the switch box door 18. A first locking block 20 is installed on the door panel 9 at the corresponding position of the first latch 19. Second latches 21 are installed on the upper and lower sides of the switch box door 18, and a second locking block 22 is installed on the door panel 9 at the corresponding position of the second latches 21. This structural design facilitates the operator in opening and closing the switch box door 18.

[0030] In this embodiment, when it is necessary to inspect the internal EC fan 11, the first locking block 20 and the second locking buckle 21 can be opened to release the first locking block 20 and the second locking buckle 21 from the fixed connection with the first locking buckle 19 and the second locking buckle 21, so that the switch box door 18 can be opened to inspect the EC fan 11 inside the fan box 1.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
