[0002] Air-cooled air conditioning units are common temperature control solutions in large spaces such as factories, widely used for production line cooling, equipment heat dissipation, and raw material storage. Currently, most applications use front-vent return air units, where the front of the unit is located in the air-conditioned area, with both the air outlet and return air vent on the same side. However, with varying application scenarios, there is an increasing demand for rear return air, simultaneous return air from both the front and rear sides, and front return air with rear fresh air. Currently, there are few models on the market that can simultaneously meet the requirements of separate front and rear return air and front return air with rear fresh air. The main challenge lies in designing a filtration structure for the return air location that can filter the return air from both the front and rear sides. Utility Model Content

[0059] As mentioned in the background section, in order to solve the technical problem of filtering the front and rear return air of the air-cooled cabinet in the prior art, this application provides a retractable filter structure and air-cooled cabinet device that can realize the arrangement of the filter screen according to the front and rear return air conditions.

[0060] Example 1

[0061] This embodiment provides a retractable filter structure for an air-cooled cabinet, which is installed inside the cabinet body 1 of the air-cooled cabinet. The cabinet body 1 has a first space 101 and a second space 102. A front air vent 11 and a rear air vent 12 are respectively opened on both sides of the cabinet body 1 corresponding to the first space 101 and the second space 102, and an air outlet 13 is opened on the top. The filter structure includes:

[0062] Heat exchanger 3 is located within the first space 101;

[0063] A water tray 4 is located below the heat exchanger 3 and is used to collect the condensate generated on the heat exchanger 3. There is a first gap between the water tray 4 and the cabinet 1, and the first gap connects the first space 101 and the second space 102.

[0064] The filter assembly 2 is located on the side of the heat exchanger 3 away from the air outlet 13. The filter assembly 2 can be deployed in the first space 101 and / or the second space 102 so that the gas enters the cabinet 1 from the front air outlet 11 and / or the rear air outlet 12, passes through the filter assembly 2 and the heat exchanger 3 in sequence, and is then discharged from the air outlet 13.

[0065] like Figure 1 and Figure 6As shown, the cabinet 1 is approximately a cuboid structure. The first space 101 and the second space 102 are both internal spaces of the cabinet 1, distributed vertically. A front air vent 11 is located in the first space 101, and a front grille is provided at the front air vent 11. A rear air vent 12 is located in the second space 102, and a rear grille is also provided at the rear air vent 12. An air outlet 13 is located at the top of the cabinet 1. The heat exchanger 3 is inclined within the first space 101, forming an angle with the horizontal direction. A water collection tray 4 is located below the heat exchanger 3 and extends horizontally. The vertical projection of the heat exchanger 3 corresponds to the vertical projection of the water collection tray 4, allowing the condensate generated on the heat exchanger 3 to be collected by the water collection tray 4 after falling. The water collection tray 4 divides the interior of the cabinet 1 into the aforementioned first space. The first space 101 and the second space 102 are connected by a first gap between the water receiving tray 4 and the cabinet 1. The filter assembly 2 is located on the side of the heat exchanger 3 away from the air outlet 13. The filter assembly 2 includes at least a first roller 21 and a first filter screen 24. The first filter screen 24 is wound on the first roller 21. When an external force pulls the free end of the first filter screen 24, the first filter screen 24 can extend and unfold from the first roller 21. After the external force is removed, the first roller 21 rotates to make the first filter screen 24 rewind onto the first roller 21. At the same time, a guide assembly can be set in the cabinet 1 to change the extension direction of the free end of the first filter screen 24 under the pull of the external force, so that the first filter screen 24 can filter the return air under the condition of return air from the front air outlet 11 and / or return air from the rear air outlet 12.

[0066] By setting a filter assembly 2 on the side of the heat exchanger 3 away from the air outlet 13, the filter assembly 2 can be arranged according to the return air conditions of the front air outlet 11 and the rear air outlet 12. When the front air outlet 11 returns air or the front and rear air outlets 12 return air at the same time, the filter assembly 2 can be deployed in the first space 101 and the second space 102. When the rear air outlet 12 returns air, the filter assembly 2 can be deployed in the second space 102, thereby meeting the return air filtration needs under different usage scenarios, with high flexibility and stronger applicability.

[0067] In a preferred embodiment, the filtering component 2 includes:

[0068] The first scroll 21 is rotatably connected to the cabinet 1 at a position near the top of the front air vent 11.

[0069] The first guide roller 22 is rotatably connected to the cabinet 1 at a position near the bottom of the front air vent 11.

[0070] The first motor 23 is fixed on the water receiving tray 4 on the side near the second space 102, and the drive end of the first motor 23 is fixed with a connecting rope.

[0071] The first filter screen 24 has one end fixed to the first roller 21, and the free end of the first filter screen 24 is fixed to the connecting rope by the hook 204 after passing through the first guide roller 22.

[0072] like Figure 2 As shown, the first roller 21 and the first guide roller 22 are rotatably connected to the cabinet 1 on both sides of the front air vent 11 in the vertical direction. The first motor 23 is fixed on the water receiving tray 4 near the second space 102 to avoid affecting the water receiving tray 4's ability to collect condensate. A connecting rope is fixed to the drive end of the first motor 23, which can be wound up or unwound under the drive of the first motor 23. There are two first motors 23 and two hooks 204. The two first motors 23 are connected along... Figure 2 The first filter screen 24 is arranged perpendicularly to the paper surface. Two hooks 204 are fixed on both sides of the free end of the first filter screen 24 in the width direction. Two connecting ropes are fixedly connected to the two hooks 204 respectively.

[0073] When the air-cooled cabinet only needs to return air through the front air vent 11 during operation, the first motor 23 is started. The first motor 23 drives the connecting rope to rewind, causing the free end of the first filter screen 24 to extend vertically. When the free end of the first filter screen 24 passes the bottom of the front air vent 11 and reaches the first guide roller 22 in the vertical direction, the first motor 23 stops. The part of the first filter screen 24 that unfolds from the first roller 21 can filter the return air entering the first space 101 from the front air vent 11.

[0074] When the air-cooled cabinet requires return air through the front air vent 11 and rear air vent 12 during operation, the first motor 23 is activated. The first motor 23 drives the connecting rope to rewind, causing the free end of the first filter screen 24 to extend vertically. When the free end of the first filter screen 24 passes the bottom of the front air vent 11 and reaches the first guide roller 22, the first guide roller 22 guides the free end of the first filter screen 24, causing it to move horizontally towards the rear air vent 12. When the free end of the first filter screen 24 passes the free end of the water receiving tray 4 and reaches the position of the first motor 23, the first motor 23... 3. Stop. At this time, the part of the first filter screen 24 that is spread out between the first roller 21 and the first guide roller 22 can filter the return air entering the first space 101 from the front air outlet 11. The part of the first filter screen 24 that is spread out between the first guide roller 22 and the first motor 23 covers the first gap and can filter the return air entering the second space 102 from the rear air outlet 12 and then entering the first space 101. Thus, the return air from the front air outlet 11 and the rear air outlet 12 is filtered. The filtered air entering the cabinet 1 from the front air outlet 11 and the rear air outlet 12 is heated by the heat exchanger 3 and then discharged from the air outlet 13.

[0075] Furthermore, since the portion of the first filter screen 24 corresponding to the water receiving tray 4 in the vertical direction is located below the water receiving tray 4 when it is unfolded, it can avoid being affected by the condensate generated on the heat exchanger 3.

[0076] In a preferred embodiment, the filtering component 2 includes:

[0077] The first scroll 21 is rotatably connected to the cabinet 1 at a position near the top of the front air vent 11.

[0078] The first guide roller 22 is rotatably connected to the cabinet 1 at a position near the bottom of the front air vent 11.

[0079] The second guide roller 25 is rotatably connected to the water receiving tray 4 on the side near the second space 102;

[0080] The third guide roller 26 is rotatably connected to the bottom of the cabinet 1;

[0081] The first motor 23 is fixed at the bottom of the cabinet 1 and located on the side of the third guide roller 26 away from the rear air vent 12. A connecting rope is fixed to the drive end of the first motor 23.

[0082] The first filter screen 24 has one end fixed to the first roller 21. The free end of the first filter screen 24 passes through the first guide roller 22, the second guide roller 25 and the third guide roller 26 in sequence, and is then fixed to the connecting rope by the hook 204.

[0083] like Figure 3As shown, the first roller 21 and the first guide roller 22 are rotatably connected to the cabinet 1 on both sides of the front air vent 11 in the vertical direction. The second guide roller 25 is rotatably connected to the side of the water tray 4 near the second space 102. The third guide roller 26 is rotatably connected to the bottom of the cabinet 1. The first motor 23 is fixed to the side of the third guide roller 26 away from the rear air vent 12. When the first motor 23 is started, it drives the connecting rope to wind up, causing the free end of the first filter screen 24 to extend vertically. When the free end of the first filter screen 24 extends to the first guide roller 22, the part of the first filter screen 24 that has been unwound from the first roller 21 can enter the first space from the front air vent 11. The return air in space 101 is filtered. Then, guided by the first guide roller 22, the first motor 23 drives the free end of the first filter screen 24 to move horizontally towards the rear air outlet 12. When the free end of the first filter screen 24 reaches the position of the second guide roller 25, the first filter screen 24 covers the first gap. The part of the first filter screen 24 that is spread out between the first guide roller 22 and the second guide roller 25 can filter the return air that enters the second space 102 from the rear air outlet 12 and then enters the first space 101, thereby achieving filtration of the return air from the front air outlet 11 and the rear air outlet 12. Then, guided by the second guide roller 25, the free end of the first filter screen 24 moves horizontally towards the rear air outlet 12. The first filter screen 24 moves towards the side closer to the third guide roller 26. When the free end of the first filter screen 24 reaches the position of the third guide roller 26, it moves to a position close to the drive end of the first motor 23 under the guidance of the third guide roller 26. At this time, the first filter screen 24 covers the second space 102. The part of the first filter screen 24 that is spread out between the second guide roller 25 and the third guide roller 26 can filter the return air entering the second space 102 from the rear air vent 12. Furthermore, the part of the first filter screen 24 that is spread out between the first guide roller 22 and the third guide roller 26 can achieve secondary filtration of the return air from the rear air vent 12. Since the rear air vent 12 is located close to the ground on the cabinet 1, its position is close to the ground. When the return air is drawn in, it will draw in more sand or impurities than the front air vent 11. Through secondary filtration, the sand and impurities in the return air can be effectively filtered out, enhancing the filtration effect. Furthermore, the first motor 23 is located on the side of the third guide roller 26 away from the rear air vent 12. The return air from the rear air vent 12 reaches the position of the first motor 23 after being filtered once by the first filter screen 24, which can effectively protect the first motor 23 from the sand and impurities in the return air and increase the service life of the first motor 23. At the same time, since the part of the first filter screen 24 that corresponds to the water receiving tray 4 in the vertical direction is located below the water receiving tray 4 when it is unfolded, it can avoid being affected by the condensate generated on the heat exchanger 3.

[0084] In a preferred embodiment, a first detection element 201 is provided on the cabinet 1 near the first guide roller 22, a second detection element 202 is provided on the water receiving tray 4 near the second guide roller 25, and a third detection element 203 is provided on the cabinet 1 near the third guide roller 26. The first detection element 201, the second detection element 202 and the third detection element 203 are communicatively connected to a controller, which is used to control the start and stop of the first motor 23.

[0085] like Figure 4 As shown, the first detection element 201 is located on the cabinet 1, between the first guide roller 22 and the bottom of the front air vent 11. The first detection element 201 is used to detect whether the free end of the first filter screen 24 has moved past the bottom of the front air vent 11. The second detection element 202 is located on the side of the water receiving tray 4 near the second space 102, between the second guide roller 25 and the free end of the water receiving tray 4. The second detection element 202 is used to detect whether the free end of the first filter screen 24 has moved past the free end of the water receiving tray 4. The third detection element 203 is located at the bottom of the cabinet 1, between the third guide roller 26 and the first motor 23. The detection element 203 is used to detect whether the free end of the first filter screen 24 has moved past the third guide roller 26. In this embodiment, the first detection element 201, the second detection element 202 and the third detection element 203 can be photoelectric detection switches in the prior art. In other embodiments, other detection elements with similar detection functions can also be used. No special limitation is made here. The first detection element 201, the second detection element 202 and the third detection element 203 are connected to the controller for communication. They can send detection signals to the controller respectively. Then the controller can control the first motor 23 to start and stop through the detection signals.

[0086] In a preferred embodiment, when the first motor 23 drives the free end of the first filter screen 24 to move to the first guide roller 22, the first detection element 201 generates a first detection signal and sends it to the controller. The controller controls the first motor 23 to stop according to the first detection signal. The gas enters the cabinet 1 from the front air outlet 11, is filtered by the first filter screen 24, and then is discharged from the air outlet 13 through the heat exchanger 3.

[0087] like Figure 4As shown, when the air-cooled cabinet only needs to return air through the front air vent 11 during operation, the controller controls the first motor 23 to start. The drive end of the first motor 23 drives the connecting rope to wind up, which in turn drives the free end of the first filter screen 24. The free end of the first filter screen 24 moves vertically from the first roller 21 towards the side close to the first guide roller 22. When the free end of the first filter screen 24 passes the bottom of the front air vent 11 and reaches the position of the first detection element 201 in the vertical direction, the first detection element 201 detects the first filter screen 24 and generates a first detection signal, which is sent to the controller. The controller controls the first motor 23 to stop according to the first detection signal. At this time, the part of the first filter screen 24 that unfolds from the first roller 21 can filter the return air entering the first space 101 from the front air vent 11. The filtered gas is discharged from the air outlet 13 after heat exchange through the heat exchanger 3.

[0088] In a preferred embodiment, when the first motor 23 drives the free end of the first filter screen 24 to move from the first guide roller 22 to the second guide roller 25, the second detection element 202 generates a second detection signal and sends it to the controller. The controller controls the first motor 23 to stop according to the second detection signal. The gas enters the cabinet 1 from the front air outlet 11 and the rear air outlet 12, is filtered by the first filter screen 24, and then is discharged from the air outlet 13 through the heat exchanger 3.

[0089] like Figure 4 As shown, when the air-cooled cabinet requires return air from the front air vent 11 and the rear air vent 12 during operation, and the environment around the rear air vent 12 is no different from that around the front air vent 11, the controller controls the first motor 23 to start. The drive end of the first motor 23 drives the connecting rope to wind up, which in turn drives the free end of the first filter screen 24, causing the free end of the first filter screen 24 to move vertically from the first roller 21 towards the side closer to the first guide roller 22. When the free end of the first filter screen 24 passes the bottom of the front air vent 11 and reaches the first guide roller 22 in the vertical direction, the first guide roller 22 guides the free end of the first filter screen 24, causing the free end of the first filter screen 24 to move horizontally towards the side closer to the rear air vent 12. When the free end of the first filter screen 24 passes the water receiving tray in the horizontal direction... When the free end of 4 reaches the position of the second detection element 202, the second detection element 202 detects the first filter screen 24 and generates a second detection signal to be sent to the controller. The controller controls the first motor 23 to stop according to the second detection signal. At this time, the part of the first filter screen 24 that is unfolded between the first roller 21 and the first guide roller 22 can filter the return air entering the first space 101 from the front air outlet 11. The part of the first filter screen 24 that is unfolded between the first guide roller 22 and the second guide roller 25 covers the first gap and can filter the return air that enters the second space 102 from the rear air outlet 12 and then enters the first space 101. The filtered gas that enters the cabinet 1 from the front air outlet 11 and the rear air outlet 12 is discharged from the air outlet 13 after heat exchange by the heat exchanger 3.

[0090] In a preferred embodiment, when the first motor 23 drives the free end of the first filter screen 24 to move to the third guide roller 26 by passing through the first guide roller 22 and the second guide roller 25 in sequence, the third detection element 203 generates a third detection signal and sends it to the controller. The controller controls the first motor 23 to stop according to the third detection signal. The gas enters the cabinet 1 from the front air inlet 11, is filtered by the first filter screen 24, and then is discharged from the air outlet 13 through the heat exchanger 3. The gas enters the cabinet 1 from the rear air inlet 12, is filtered twice by the first filter screen 24, and then is discharged from the air outlet 13 through the heat exchanger 3.

[0091] like Figure 4 As shown, when the air-cooled cabinet requires return air from the front air vent 11 and the rear air vent 12 during operation, and the environment around the rear air vent 12 is relatively harsh, the controller controls the first motor 23 to start. The drive end of the first motor 23 drives the connecting rope to wind up, which in turn drives the free end of the first filter screen 24, causing the free end of the first filter screen 24 to move vertically from the first roller 21 towards the side closer to the first guide roller 22. When the free end of the first filter screen 24 passes the bottom of the front air vent 11 and reaches the first guide roller 22 in the vertical direction, the first guide roller 22... The free end of the first filter screen 24 is guided to move horizontally towards the rear air inlet 12. When the free end of the first filter screen 24 passes the free end of the water receiving tray 4 and reaches the second guide roller 25, the second guide roller 25 guides the free end of the first filter screen 24 to move towards the third guide roller 26. When the free end of the first filter screen 24 reaches the third guide roller 26, the third guide roller 26 guides the free end of the first filter screen 24 to move horizontally towards the rear air inlet 12. The free end of the first filter screen 24 moves horizontally towards the side closer to the first motor 23. When the free end of the first filter screen 24 reaches the position of the third detection element 203, the third detection element 203 detects the first filter screen 24 and generates a third detection signal, which is sent to the controller. The controller controls the first motor 23 to stop according to the third detection signal. At this time, the unfolded part of the first filter screen 24 located between the first roller 21 and the first guide roller 22 can filter the return air entering the first space 101 from the front air inlet 11. The first filter screen 24 is located on the second guide roller. The portion of the first filter screen 24 between the first guide roller 22 and the second guide roller 25 covers the second space 102, which can filter the return air entering the second space 102 from the rear air outlet 12. The portion of the first filter screen 24 between the first guide roller 22 and the second guide roller 25 covers the first gap, which can filter the return air entering the second space 102 from the rear air outlet 12 and then entering the first space 101. The filtered gas entering the cabinet 1 from the front air outlet 11 and the rear air outlet 12 is discharged from the air outlet 13 after heat exchange by the heat exchanger 3.

[0092] In a preferred embodiment, the filtering component 2 includes:

[0093] The first scroll 21 is rotatably connected to the cabinet 1 at a position near the top of the front air vent 11.

[0094] The first motor 23 is fixed on the cabinet 1 near the bottom of the front air vent 11, and the drive end of the first motor 23 is fixed with a connecting rope.

[0095] The first filter screen 24 has one end fixed to the first roll 21, and the free end of the first filter screen 24 extends vertically and is fixed to the connecting rope by the hook 204.

[0096] The second scroll 27 is rotatably connected to the water receiving tray 4 on the side near the second space 102;

[0097] The first guide roller 22 is rotatably connected to the bottom of the cabinet 1;

[0098] The second motor 28 is fixed at the bottom of the cabinet 1 and located on the side of the first guide roller 22 away from the rear air vent 12. A connecting rope is fixed to the drive end of the second motor 28.

[0099] The second filter screen 29 has one end fixed to the second roller 27. The free end of the second filter screen 29 extends vertically and passes through the first guide roller 22 before being fixed to the connecting rope by the hook 204.

[0100] like Figure 5 As shown, the first spool 21 is rotatably connected to the cabinet 1 and located above the front air vent 11. The first motor 23 is fixed to the solid and located below the front air vent 11. The connecting rope is fixed to the drive end of the first motor 23 and can be wound up or unwound under the drive of the first motor 23. The second spool 27 is rotatably connected to the water receiving tray 4 on the side near the second space 102. The first guide roller 22 is rotatably connected to the bottom of the cabinet 1. The second motor 28 is fixed to the bottom of the cabinet 1 and located on the side of the first guide roller 22 away from the rear air vent 12. The drive end of the second motor 28 is also fixed with a connecting rope.

[0101] When the air-cooled cabinet only needs to return air through the front air vent 11 during operation, the first motor 23 is started. The drive end of the first motor 23 drives the connecting rope to wind up, which in turn drives the free end of the first filter screen 24. The free end of the first filter screen 24 moves vertically from the first roller 21 towards the side closer to the first motor 23. When the free end of the first filter screen 24 passes the bottom of the front air vent 11 and reaches the position of the first motor 23 in the vertical direction, the first motor 23 stops. At this time, the part of the first filter screen 24 that unfolds from the first roller 21 can filter the return air entering the first space 101 from the front air vent 11. The filtered gas is discharged from the air outlet 13 after heat exchange through the heat exchanger 3.

[0102] When the air-cooled cabinet only needs to return air through the rear air vent 12 during operation, the second motor 28 is started. The drive end of the second motor 28 drives the connecting rope to wind up, which in turn drives the free end of the second filter screen 29. The free end of the second filter screen 29 moves vertically from the second roller 27 towards the side closer to the first guide roller 22. When the free end of the second filter screen 29 reaches the first guide roller 22, the first guide roller 22 guides the free end of the second filter screen 29, causing the free end of the second filter screen 29 to move horizontally towards the side closer to the second motor 28. When the free end of the second filter screen 29 reaches the position of the second motor 28, the second motor 28 stops. At this time, the part of the second filter screen 29 that is spread out between the second roller 27 and the first guide roller 22 covers the second space 102, which can filter the return air entering the second space 102 from the rear air vent 12. The filtered gas is discharged from the air outlet 13 after heat exchange through the heat exchanger 3.

[0103] When the air-cooled cabinet requires both the front air vent 11 and the rear air vent 12 to return air during operation, the first motor 23 and the second motor 28 are activated. The drive end of the first motor 23 drives the connecting rope to rewind, which in turn drives the free end of the first filter screen 24, causing the free end of the first filter screen 24 to move vertically from the first roller 21 towards the side closer to the first motor 23. When the free end of the first filter screen 24 reaches the position of the first motor 23 after passing the bottom of the front air vent 11 in the vertical direction, the first motor 23 stops. At this time, the part of the first filter screen 24 that has unfolded from the first roller 21 can filter the return air entering the first space 101 from the front air vent 11. At the same time, the drive end of the second motor 28 drives the connecting rope to rewind, which in turn drives the free end of the second filter screen 29, causing the free end of the second filter screen 29 to move vertically towards the side closer to the first motor 23. Starting from the second roller 27, the filter screen 29 moves vertically towards the side closer to the first guide roller 22. When the free end of the second filter screen 29 reaches the first guide roller 22, the first guide roller 22 guides the free end of the second filter screen 29, causing the free end of the second filter screen 29 to move horizontally towards the side closer to the second motor 28. When the free end of the second filter screen 29 reaches the position of the second motor 28, the second motor 28 stops. At this time, the part of the second filter screen 29 that is spread out between the second roller 27 and the first guide roller 22 covers the second space 102, which can filter the return air entering the second space 102 from the rear air outlet 12. The return air from the front air outlet 11 and the rear air outlet 12 is filtered by the first filter screen 24 and the second filter screen 29 respectively, and then heat-exchanged by the heat exchanger 3 before being discharged from the air outlet 13.

[0104] Based on the above, when the first filter screen 24 and the second filter screen 29 are unfolded, the parts of both corresponding to the water receiving tray 4 in the vertical direction are located below the water receiving tray 4. This can prevent the first filter screen 24 and the second filter screen 29 from being interfered with by the condensate generated on the heat exchanger 3, thus affecting their filtration effect. At the same time, the second motor 28 is located on the side of the first guide roller 22 away from the rear air outlet 12. After the return air from the rear air outlet 12 enters the second space 102, it first passes through the part of the second filter screen 29 that is unfolded between the second roller 27 and the first guide roller 22 before reaching the first motor 23. This can effectively protect the second motor 28 from sand and impurities in the return air and increase the service life of the second motor 28.

[0105] Furthermore, if the environment around the rear air vent 12 is harsh, the fixed position of the first motor 23 can be adjusted and the number of guide rollers can be increased so that the second filter screen 29 can form a two-stage or multi-stage filtration structure in the second space 102 after it is fully unfolded.

[0106] In a preferred embodiment, the filtering component 2 includes:

[0107] The first scroll 21 is rotatably connected to the water receiving tray 4 on the side near the second space 102;

[0108] The first filter screen 24 has one end fixed to the first roller 21, and the free end of the first filter screen 24 is fixed to the top of the front air vent 11 by a hook 204.

[0109] like Figure 6 As shown, the filter screen of the filter assembly 2 can also be unfolded manually. The first roller 21 is rotatably connected to the side of the water receiving tray 4 near the second space 102, located near the free end of the water receiving tray 4. When installing the filter assembly 2, the operator can manually pull the free end of the first filter screen 24 so that the free end of the first filter screen 24 passes through the first gap under the action of external force and extends towards the top of the front air vent 11, and is fixed to the top of the front grille of the front air vent 11 by the hook 204. When the air-cooled cabinet needs the front air vent 11 and the rear air vent 12 to return air together during operation, the return air of the front air vent 11 and the rear air vent 12 can pass through the unfolded first filter screen 24 together, and after heat exchange in the heat exchanger 3, it is discharged from the air outlet 13.

[0110] Example 2

[0111] This embodiment provides an air-cooled cabinet device, including a retractable filter structure for an air-cooled cabinet as described in Embodiment 1.

[0112] like Figure 7-9As shown, the air-cooled cabinet includes a cabinet 1, which is approximately a cuboid structure. A front air vent 11 and a rear air vent 12 are respectively opened along the width direction (i.e., the front-to-back direction) of the cabinet 1. The rear air vent 12 is located on the cabinet 1 near the bottom. The front air vent 11 is higher in the vertical direction than the rear air vent 12. Front and rear grilles are respectively installed at the front and rear air vents 11 and 12. The grilles serve not only for ventilation but also for safety, dust prevention, and airflow optimization. They ensure efficient flow of hot and cold air. By designing the opening direction and density of the grilles, the flow of hot and cold air can be prevented. The air mixing system improves cooling efficiency and prevents accidental contact with the high-speed rotating fan blades or high-temperature components inside. It also prevents large particles of debris from falling into the cabinet 1 and damaging the equipment, serving as the first line of defense for the cabinet 1. An operation panel is located above the front air vent 11 on the outside of the cabinet 1. This panel is electrically connected to the controller of the air-cooled unit, allowing operators to control the unit via touch. An air outlet 13 is located at the top of the cabinet 1, and a fan is positioned inside the cabinet 1 near the outlet 13. The fan's exhaust port corresponds to the outlet 13. The heat exchanger 3 is inclined inside the cabinet 1, forming an angle with the horizontal direction. A water tray 4 is located below the heat exchanger 3 and extends horizontally. The vertical projection of the heat exchanger 3 corresponds to the vertical projection of the water tray 4, allowing the condensate generated on the heat exchanger 3 to be collected by the water tray 4 and discharged to the outside of the cabinet 1. The air-cooled cabinet device, equipped with a front air vent 11 and a rear air vent 12, has multiple operating modes, including separate air return from the front air vent 11 and rear air vent 12, combined air return from both the front and rear air vents 11, and air return from the front air vent 11 while fresh air enters from the rear air vent 12. The filter assembly 2 is located on the side of the heat exchanger 3 away from the air outlet 13 and includes a roller, a filter screen, and a motor. The filter screen is wound onto a roller and guide roller. When the motor rotates forward, it drives the free end of the filter screen to move, allowing the filter screen to extend and unfold from the roller. When the motor rotates in reverse, the roller rotates, causing the filter screen to be wound onto the roller. The roller can also be replaced with other electric winding devices, so that both the unfolding and winding of the filter screen are completed by motor drive. The guide roller is set on a fixed structure inside the cabinet 1 to guide the unfolded filter screen and facilitate the layout of the filter screen. By setting the filter assembly 2 with the above structure, it can be unfolded inside the cabinet 1 according to actual needs, thereby filtering the return air from the front air vent 11 and / or the rear air vent 12 in different working modes.
