Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and more specifically relates to a steady flow guiding device for an air conditioning unit. Background Art

[0002] In some air-conditioning units, the eddy currents generated between the return air flow and the fan repeatedly collide in the wind cover at the fan air inlet, causing the pressure inside the return air duct and the wind cover to be extremely unstable, which can easily cause the entire unit to vibrate. In order to better guide the airflow into the fan and avoid the vibration of the unit, large-volume flow stabilizers are often welded at the fan air inlet.

[0003] However, during the welding process of the flow stabilizer, multiple workers are required to hold the flow stabilizer by hand to stabilize it. Long-term holding will cause fatigue among the workers, causing the flow stabilizer to deviate from the predetermined position, thus requiring realignment, which reduces the installation efficiency of the flow stabilizer.

[0006] In a possible implementation, a rotating sleeve is rotatably provided on the outer circumferences of the two threaded sleeves, and the two rotating sleeves are connected by a connecting strip.

[0007] In some embodiments, the connecting strip is arched downward and is located outside the avoidance opening.

[0023] The air conditioning unit includes a fan 1 with an air inlet 4 facing one side, a hood 2 covered on one side of the fan 1, and a return air duct 3 connected to the top of the hood 2. The hood 2 is arranged opposite to the air inlet 4, and the air flow enters the hood 2 from the return air duct 3 and enters the air inlet 4.

[0024] See also Figures 1 to 5 , the flow-stabilizing and guiding device for air-conditioning units provided by the utility model is now described. The flow-stabilizing and guiding device for air-conditioning units comprises two inserting pipes 20, a flow-stabilizing box 10 and two threaded sleeves 30. The two inserting pipes 20 are connected to the side wall of the fan 1 close to the air inlet 4 and are symmetrically arranged on both sides of the air inlet 4; the flow-stabilizing box 10 is arranged in the wind cover 2 and has an upward opening. The side wall of the flow-stabilizing box 10 close to the fan 1 is penetrated with a plug hole 12 for plugging and matching with the inserting pipe 20. The side wall of the flow-stabilizing box 10 close to the fan 1 is penetrated with a avoidance 11 connected with the air inlet 4. The flow-stabilizing box 10 is used to buffer and guide the airflow into the air inlet 4; the two threaded sleeves 30 correspond to each other one by one. The threaded sleeves 30 are arranged on the outer periphery of the two inserting pipes 20 and are located in the flow-stabilizing box 10. The threaded sleeves 30 can axially push the flow-stabilizing box 10 to abut against the fan 1 to lock the axial position of the flow-stabilizing box 10.

[0025] The embodiment of the present application provides a flow-stabilizing and guiding device for an air-conditioning unit. During its actual use, a plug 20 is first welded at a preset position of the fan 1, and then the two sockets 12 on the flow-stabilizing box 10 are respectively aligned with the two plugs 20, and the plugs 20 are inserted into the sockets 12. Finally, a threaded sleeve 30 is sleeved on the outer periphery of the plugs 20, and the flow-stabilizing box 10 is rotated and pushed to abut against the side wall of the fan 1, thereby completing the locking of the relative position of the flow-stabilizing box 10 and the fan 1. By means of the plug-in positioning of the plug 20 and the socket 12 and the locking of the position of the flow-stabilizing box 10 by the threaded sleeve 30, the flow-stabilizing box 10 can be quickly and accurately installed at the preset position of the fan 1, thereby improving the installation efficiency of the flow-stabilizing box 10.

[0026] Compared with the prior art, the flow stabilizing and guiding device for an air-conditioning unit provided in the present embodiment aligns the two insertion holes 12 on the flow stabilizing box 10 with the two insertion tubes 20 respectively, and the insertion tubes 20 are inserted into the insertion holes 12, and finally the threaded sleeve 30 is sleeved on the outer periphery of the insertion tube 20, and the flow stabilizing box 10 is rotated and pushed to abut against the side wall of the fan 1, thereby completing the locking of the relative position of the flow stabilizing box 10 and the fan 1. By means of the plug-in positioning of the insertion tube 20 and the insertion hole 12 and the locking of the position of the flow stabilizing box 10 by the threaded sleeve 30, the flow stabilizing box 10 can be quickly and accurately installed at the preset position of the fan 1, thereby improving the installation efficiency of the flow stabilizing box 10.

[0027] In a possible implementation, the threaded sleeve 30 is Figure 1 , Figure 2 and Figure 4 The structure shown, see Figure 1 , Figure 2 and Figure 4 The outer circumferences of the two threaded sleeves 30 are both provided with a rotating sleeve 40 , and the two rotating sleeves 40 are connected by a connecting strip 41 .

[0028] Specifically, the rotating sleeve 40 is rotatably connected to the threaded sleeve 30. When installing the threaded sleeve 30, it is necessary to rotate the two threaded sleeves 30 at the same time (that is, the axial movement distances of the two threaded sleeves 30 on the corresponding plug 20 are synchronized) so that they can push the flow stabilizer box 10 to the side wall of the fan 1. During the normal use of the fan 1, due to the restriction of the two threaded sleeves 30 by the connecting strip 41, when one of the threaded sleeves 30 has a tendency to move toward the outer end of the plug 20 due to vibration, the position of the other threaded sleeve 30 is stable, and the threaded sleeve 30 with a tendency to move is restricted by the connecting strip 41, thereby avoiding the loosening of the threaded sleeve 30 due to vibration.

[0029] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The connecting strip 41 is arched downward and is located on the outside of the avoidance opening 11 .

[0030] Specifically, the connecting strip 41 is in an arc shape, avoiding the avoidance opening 11 to avoid interfering with the air entering the air inlet 4 .

[0031] In a possible implementation, the above-mentioned flow stabilizing box 10 adopts Figure 1 , Figure 2 and Figure 4 The structure shown, see Figure 1 , Figure 2 and Figure 4 The side wall of the flow stabilizing box 10 opposite to the air inlet hole 4 gradually extends from top to bottom in an inclined direction close to the fan 1.

[0032] Specifically, the side wall of the flow stabilizing box 10 opposite to the air inlet 4 is inclined so as to buffer and guide the airflow entering the flow stabilizing box 10 so that it enters the air inlet 4 stably, thereby preventing the airflow from colliding around in the wind cover 2 and causing vibration of the unit.

[0033] Furthermore, the acute angle between the side wall of the stabilizing box 10 opposite to the air inlet 4 and the horizontal plane is 45 degrees.

[0034] Furthermore, the distance between the upper edge of the side wall of the stabilizing box 10 opposite to the air inlet hole 4 and the fan 1 is 937 mm, and the distance between the lower edge of the side wall of the stabilizing box 10 opposite to the air inlet hole 4 and the fan 1 is 150 mm.

[0035] In a possible implementation, the above-mentioned flow stabilizing box 10 adopts Figure 1 , Figure 2 and Figure 4 The structure shown, see Figure 1 , Figure 2 and Figure 4 The two side walls of the flow stabilizing box 10 adjacent to the avoidance opening 11 gradually extend inwardly from top to bottom.

[0036] Specifically, the two side walls of the flow stabilizing box 10 adjacent to the avoidance opening 11 gradually approach each other from top to bottom, so as to buffer and guide the airflow entering the flow stabilizing box 10 so as to stably enter the air inlet 4 .

[0037] In a possible implementation, the avoidance opening 11 is as follows: Figure 1 , Figure 2 and Figure 4 The structure shown, see Figure 1 , Figure 2 and Figure 4 The avoidance opening 11 extends upward to the upper port of the stabilizing box 10 .

[0038] Specifically, the top of the air inlet 4 is higher than the upper port of the stabilizing box 10, so that the airflow entering the stabilizing box 10 can be buffered on the inner bottom wall of the stabilizing box 10 and then turned back to enter the air inlet 4, effectively avoiding vibration of the unit.

[0039] Furthermore, this installation method of the flow stabilizer box 10 can buffer the airflow entering the wind hood 2 and make it stably enter the flow stabilizer box 10. The optimal specifications are selected through a large number of CFD simulations and practices, thereby avoiding vibration of the unit.

[0040] In a possible implementation, the above-mentioned flow stabilizing box 10 adopts Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 , the flow stabilizer box 10 is welded to the fan 1.

[0041] Specifically, the welding of the flow stabilizer box 10 and the fan 1 further increases the connection stability between the flow stabilizer box 10 and the fan 1 .

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
