Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of base station heat dissipation, and in particular to a wireless communication base station cooling system and a cooling method. BACKGROUND

[0002] A 5G base station is a core device of a 5G network, provides wireless coverage, and realizes wireless signal transmission between a wired communication network and a wireless terminal. The architecture and form of the base station directly affect how the 5G network is deployed. Since the higher the frequency, the greater the signal attenuation in the signal propagation process, the density of the base station of the 5G network will be higher. The widespread use of the 5G base station brings the problem of heat generation of the 5G base station itself. When the heat is accumulated in the base station and the internal temperature of the base station is too high, the normal work of the base station will be affected.

[0003] The heat dissipation fan is installed at a proper position of the cabinet, usually the front, side or top of the cabinet, so as to be able to effectively suck in cold air from the external environment. When the fan is started, it will form an air current to suck in the external air with relatively low temperature into the cabinet, and discharge it from the top front or side of the cabinet. The flowing air can dissipate heat for the base station devices in the cabinet.

[0004] The above-mentioned mode is a common heat dissipation mode, but the heat dissipation effect is insufficient. For example, the concrete floor is heated by solar radiation in summer, which releases a large amount of heat, and the temperature of the sucked air is also higher than the normal temperature, which is not conducive to the heat dissipation of the base station devices. The base station energy-saving cooling device with the publication number CN118828245A only cools the air through a simple water curtain. Although this cooling has an effect, it is not ideal, mainly because the heat exchange flow channel for the air is short, resulting in a short time, and thus not ideal.

[0005] Therefore, the present application provides a wireless communication base station cooling system and a cooling method. SUMMARY

[0006] The purpose of the present application is to solve the above technical problems, and a wireless communication base station cooling system and a cooling method are provided.

[0007] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0008] A wireless communication base station cooling system, comprising a cooling device installed outside a wireless communication base station cabinet and conveying air cooled therein;

[0009] The cooling device comprises a conveying part with lower end immersed in water, and a plurality of atomized heat exchange parts are arranged in the conveying part, and the conveying part can immerse the atomized heat exchange parts when circulating; when external air enters into the wireless communication base station cabinet through the cooling device, the air blows to the conveying part and the atomized heat exchange parts, and the water in the atomized heat exchange parts is blown to generate water mist, and the atomized heat exchange parts are dehydrated.

[0014] Preferably, when the air blows to the atomized heat exchange part, the flexible water absorbing element on the connecting strip can be rotated to a horizontal state, and four adjacent flexible water absorbing elements form an atomized cooling channel.

[0015] Preferably, the transmission part comprises two first pulleys and two second pulleys arranged in the cooling box, the second pulleys are arranged below the first pulleys, the outer surfaces of the first pulleys and the second pulleys in the numerical direction are provided with transmission belts abutting each other, the movable belt is arranged on the transmission belts, and a motor is arranged on the cooling box to drive the first pulleys and the second pulleys to rotate.

[0016] Preferably, the horizontal distance between the two first pulleys and the horizontal distance between the two second pulleys are greater than the length of the connecting strip.

[0017] Preferably, a flexible combing part for combing the plurality of flexible water absorbing elements on the connecting strip is further arranged coaxially with the first pulley, the flexible combing part can comb each atomization heat exchange part and detect the winding or knotting state of the flexible water absorbing element through the change of the rotation angle.

[0018] Preferably, the flexible combing part comprises a movable rod arranged through the first pulley, the outer wall of the movable rod is provided with a plurality of combing rods, when the plurality of combing rods abut against the plurality of flexible water absorbing elements on the connecting strip, the combing rods are staggered with the flexible water absorbing elements, the end of the movable rod is rotatably installed on the inner side wall of the cooling box through a torsional spring, and the end of the movable rod is connected with a rotation angle measuring instrument for detecting the rotation angle of the movable rod.

[0019] The application further discloses a cooling method of a wireless communication base station.

[0020] S1, the motor drives the first pulley and the second pulley to rotate, so that the movable belt circulates and rotates in the cooling box, and then the atomization heat exchange parts are sequentially soaked;

[0021] S2, when the soaked atomization heat exchange parts are transported to the opposite side of the air guide frame along the conveying part, the wind in the cooling box blows to the atomization heat exchange parts through the air inlet and the air guide frame; when the wind blows to the atomization heat exchange parts, the flexible water absorbing elements are in a horizontal state and parallel to the blowing direction of the wind; the four adjacent flexible water absorbing elements form a cooling channel, and when the wind blows to the flexible water absorbing elements, the water in the flexible water absorbing elements is blown and dispersed in the cooling channel to generate water mist, so that the flowing air is heat exchanged;

[0022] S3, the flexible water absorbing elements moving above the air inlet rotate downward due to gravity, and the flexible water absorbing elements are combed by the combing rods when passing through the flexible combing part;

[0023] S4, when the combed flexible water absorbing elements move to the side opposite to the air inlet, the flexible water absorbing elements form an adsorption layer on the movable belt due to gravity, the heat exchanged air with water mist contacts and adsorbs through the adsorption layer, and then enters the inside of the wireless communication base station cabinet to cool the inside of the wireless communication base station cabinet.

[0024] Compared with the prior art, the application has the following beneficial effects:

[0025] 1. When the air blows to the atomization heat exchange part, the soaked flexible water absorbing element is blown to a horizontal state from the original state of being attached to the movable belt, the four adjacent flexible water absorbing elements form an atomized cooling channel, and the air heat exchange time and path are greatly increased. At the same time, the water mist evaporates and absorbs the heat in the air to heat exchange and cool the air, thereby improving the heat exchange effect and solving the problem of unsatisfactory cooling effect caused by short air heat exchange flow channel and short heat exchange time in the prior art.

[0026] 2. The circulating activity of the conveying section wets the atomizing heat exchange section. When external air enters, it blows towards the conveying section and the atomizing heat exchange section, causing the water inside the atomizing heat exchange section to disperse and generate water mist. The air is cooled by heat exchange in the atomizing cooling channel, which effectively reduces the temperature of the air entering the base station cabinet and overcomes the problem that the high temperature of the intake air is not conducive to the heat dissipation of base station devices.

[0027] 3. The cooling device employs atomized heat exchange and a secondary heat exchange structure to cool the air entering the wireless communication base station cabinet twice. The first cooling is achieved through heat exchange between the air and water mist in the atomized cooling channel; the second cooling is achieved through a secondary heat exchange structure formed by stacked flexible water-absorbing components, where the evaporation of water absorbs heat and cools the air again, further improving the cooling effect. This effectively reduces the temperature inside the wireless communication base station cabinet, ensuring the normal operation of the base station components.

[0028] 4. The movable belt is made of nylon mesh, which allows air to enter while filtering dust and other particles, purifying the air entering the base station cabinet. Simultaneously, the air entering the cooling device is humidified through atomized cooling channels, preventing dry air from entering the base station cabinet and generating static electricity. Stacked flexible water-absorbing components treat water mist, preventing excessive humidity from affecting electrical operation. Humidity is controlled within a suitable range of 40%-60%, minimizing static electricity and condensation.

[0029] 5. The flexible combing section can comb each atomizing heat exchanger. If adjacent flexible absorbent parts are knotted, it will drive the combing rod and the movable rod to rotate. The rotation angle measuring instrument counts the rotations. When the number of rotations exceeds the set value, an alarm will sound to remind the staff to deal with the knotted parts, ensuring the stable operation of the entire cooling device. If it is just simple tangling, the combing rod can comb the tangled flexible absorbent parts to separate them for subsequent use, thereby ensuring the quality of cooling.

[0030] 6. The cleaning mechanism uses a synchronous belt to drive the rotating shaft and the long tube to rotate synchronously with a speed difference. Using a cleaning brush fixed on the rotating shaft, the surface of the moving belt can be cleaned to ensure ventilation, better filter the air, and reduce the impact of dust and other impurities on the cooling device and base station cabinet.

[0031] 7. By using airflow to blow water onto the flexible water-absorbing component to form a water mist, the existing technology does not require a separate pump structure to form a water curtain with water mist. The cooling system structure of this application is simpler and has a better air heat exchange effect, reducing equipment costs and maintenance difficulty.

[0032] In summary, the air blowing to the atomization heat exchange part, the flexible water absorbing part is blown to the horizontal state from the original state of being attached to the moving belt, and the four adjacent flexible water absorbing parts form the atomized cooling channel, which greatly increases the air heat exchange time and path. At the same time, the water mist evaporates and absorbs the heat in the air, and the air is cooled and exchanged, which improves the heat exchange effect and solves the problem of short air heat exchange flow channel, short heat exchange time and poor cooling effect in the prior art.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0049] REFERENCE Figures 1-14 A wireless communication base station cooling system includes a cooling device 200 installed outside a wireless communication base station cabinet 100 and conveying air cooled by the cooling device 200 into the wireless communication base station cabinet 100. A heat dissipation exhaust fan 110 is installed on the top of the wireless communication base station cabinet 100, which can exhaust heat inside the wireless communication base station cabinet 100. External air is cooled by the cooling device 200 and enters the wireless communication base station cabinet 100 through the communication port 2113 at the back side.

[0050] The cooling device 200 includes a conveying part 260 with its lower end immersed in water, and a plurality of atomization heat exchange parts 261 arranged inside the conveying part 260. The atomization heat exchange parts 261 can be wetted when the conveying part 260 circulates. When external air enters the wireless communication base station cabinet 100 through the cooling device 200, the air blows towards the conveying part 260 and the atomization heat exchange parts 261, disperses the water inside the atomization heat exchange parts 261 to generate water mist, and dehydrates the atomization heat exchange parts 261.

[0051] The blown atomized heat exchange part 261 deflects and is parallel to the direction of air flow, a plurality of atomized cooling channels are formed between the adjacent two atomized heat exchange parts 261, and air enters the atomized cooling channels for heat exchange cooling; the plurality of atomized heat exchange parts 261 are stacked at the inner side surface of the conveying part 260 after being blown away due to gravity, forming a secondary heat exchange structure, and air enters the wireless communication base station cabinet 100 after heat exchange through the secondary heat exchange structure.

[0052] As shown in Figure 3 , Figure 4 , the cooling device 200 further comprises a cooling box 210 arranged outside the wireless communication base station cabinet 100, the cooling box 210 is provided with a box door 211, the upper end of the box door 211 is hingedly connected with the upper end of the cooling box 210, and the lower end can be locked by a door lock to ensure stability; a plurality of air inlets 2111 are formed in the box door 211, and a wind guide frame 2112 opposite to the air inlets 2111 is arranged on the inner side wall of the box door 211, so that the air entering the cooling box 210 is more concentrated; when the box door 211 is closed, the wind guide frame 2112 is arranged close to the conveying part 260, and the two do not abut against each other, so as to avoid abrasion or damage.

[0053] As shown in Figure 4 , Figure 5 , Figure 6 , the conveying part 260 further comprises a movable belt 262 arranged in the shape of a mesh conveying belt, the movable belt 262 is a nylon mesh cloth, which can ensure air entering while filtering dust in the air; the cooling box 210 is provided with two transmission parts 230 arranged in an upper-lower distribution manner, and the movable belt 262 is arranged on the outer surface of the two transmission parts 230, so that the transmission parts 230 can move the movable belt 262 when rotating; the cooling box 210 is filled with clean water, and the liquid surface of the clean water is located above the lower transmission part 230, and the clean water is used to wet the atomized heat exchange part 261.

[0054] As shown in Figure 12 , Figure 13 , the atomized heat exchange part 261 comprises a connecting strip 2611 and a flexible water-absorbing element 2612, the connecting strip 2611 is a cloth strip, which is light in weight and breathable; the flexible water-absorbing element 2612 is a cotton thread or a thread made of other materials, which is water-absorbing and loose; the flexible water-absorbing element 2612 is arranged on the connecting strip 2611, and the flexible water-absorbing element 2612 is fixed on the connecting strip 2611 by means of glue or sewing; the connecting strip 2611 is arranged on the inner side surface of the movable belt 262, and the connecting strip 2611 is fixed on the movable belt 262 by sewing;

[0055] The flexible water-absorbing elements 2612 are linearly arranged in the length direction of the connecting strip 2611, and the length of the flexible water-absorbing element 2612 is greater than the length between the adjacent two connecting strips 2611, as shown in Figure 14As shown, the first end of the flexible water absorption member 2612 is located close to the connecting strip 2611, and the tail end is away from the first end; when the flexible water absorption member 2612 is not affected by the wind, it will swing downward due to gravity with the part of the connecting strip 2611 as the fixed point, and finally the tail end of the part covers the first end of the adjacent flexible water absorption member 2612 on the lower side; therefore, when the flexible water absorption member 2612 is not affected by the air and the numerical direction, the adjacent flexible water absorption member 2612 will be stacked from head to tail, forming an adsorption layer for filtering water mist, which is also a secondary cooling structure. When the air blows to this part and passes through this part, the water on the adsorption layer will evaporate and absorb heat, thereby realizing secondary cooling.

[0056] As shown in Figure 12 , Figure 13 , when the air blows to the atomizing heat exchange part 261, the flexible water absorption member 2612 located on the connecting strip 2611 can be rotated to a horizontal state, and the adjacent four flexible water absorption members 2612 form an atomizing cooling channel. Multiple atomizing cooling channels are connected in communication, and the cooling channel can increase the contact time of water mist and air, thereby improving the cooling effect. At the same time, the air flow is blown to the flexible water absorption member 2612 to form water mist, and there is no need to separately set a pumping structure to form a water curtain with water mist as required by the prior art. The present application is simpler and has better air heat exchange effect.

[0057] As shown in Figure 5 , Figure 8 , Figure 10 , the transmission part 230 includes two first pulleys 231 and two second pulleys 235 rotatably arranged in the cooling box 210. The horizontal distance between the two first pulleys 231 and the horizontal distance between the two second pulleys 235 are greater than the length of the connecting strip 2611; the outer side wall of the first pulley 231 is fixed with a short pipe 232, and the short pipe 232 is rotatably installed on the inner side wall of the cooling box 210 through a bearing; since the two first pulleys 231 are separately arranged, the space between them can accommodate the flexible carding part 240 and the atomizing heat exchange part 261.

[0058] The two second pulleys 235 are provided with a fixed long pipe 234 penetrating through them, and the two ends of the long pipe 234 are rotatably installed on the inner wall of the cooling box 210 through bearings; since the two second pulleys 235 are separately arranged, the space between them can accommodate the atomizing heat exchange part 261, so that it will not be affected when circulating, and also provides a space for the atomizing heat exchange part 261 to spread out in water.

[0059] The second pulley 235 is located below the first pulley 231, and the first pulley 231 and the second pulley 235 are of the same size; the outer surfaces of the first pulley 231 and the second pulley 235 in the numerical direction are provided with abutting transmission belts 233, and the movable belt 262 is fixedly arranged on the transmission belt 233; and the cooling box 210 is provided with a motor 220 for driving the first pulley 231 and the second pulley 235 to rotate.

[0060] As Figure 3 , Figure 4 , Figure 9 , Figure 10 , further comprising a flexible combing part 240 coaxially arranged with the first pulley 231 for combing the plurality of flexible water absorbing elements 2612 on the connecting strip 2611; the flexible combing part 240 can comb each atomization heat exchange part 261, and detect the winding or knotting state of the flexible water absorbing element 2612 through the change of the rotation angle.

[0061] As Figure 10 indicated, the flexible combing part 240 comprises a movable rod 242 arranged through the first pulley 231, the movable rod 242 passes through the short pipe 232 and is rotationally connected thereto through a bearing; the outer wall of the movable rod 242 is provided with a plurality of combing rods 243; when the plurality of combing rods 243 abut against the plurality of flexible water absorbing elements 2612 on the connecting strip 2611, the combing rods 243 are staggered with the flexible water absorbing elements 2612; the end of the movable rod 242 is rotationally mounted on the inner side wall of the cooling box 210 through a torsional spring, the torsional spring is used for resetting the movable rod 242 and also provides an initial reset condition for the encoder.

[0062] The end of the movable rod 242 is connected with a rotation angle measuring instrument 241 for detecting the rotation angle of the movable rod 242; the rotation angle measuring instrument 241 can be an encoder or other angle measuring instrument; if the adjacent flexible water absorbing elements 2612 are knotted, this part will hang on the combing rod 243 and drive the combing rod 243 and the movable rod 242 to rotate, and finally the two are separated, and will not affect the normal operation of the equipment;

[0063] If there is no knotting, the combing rod 243 and the movable rod 242 will not be driven to rotate; the rotation angle measuring instrument 241 counts after rotation; if the number of rotations is greater than a set value, an alarm can be connected to alarm and remind the staff to handle the knotted part.

[0064] If it is only a simple winding, the combing rod 243 can comb the wound flexible water absorbing element 2612 to separate it for subsequent use, thereby ensuring the quality of cooling.

[0065] The cleaning mechanism 250 for cleaning the outer surface of the movable belt 262 comprises a rotating shaft 251 rotatably mounted on the inner wall of the cooling box 210 through bearings at both ends, a first transmission wheel 255 fixed on the rotating shaft 251, a second transmission wheel 253 fixedly mounted on the long pipe 234, the diameter of the second transmission wheel 253 being larger than that of the first transmission wheel 255, and the two being connected through a synchronous belt 254, so that the two rotate synchronously with a speed difference. The cleaning brush 252 fixed on the rotating shaft 251 can clean the surface of the movable belt 262, ensuring the ventilation effect and better filtering treatment of the air.

[0066] The application further discloses a cooling method of a wireless communication base station.

[0067] S1, the motor 220 drives the first pulley 231 and the second pulley 235 to rotate, so that the movable belt 262 rotates in the cooling box 210, and then the atomization heat exchange part 261 is sequentially soaked.

[0068] S2, when the soaked atomization heat exchange part 261 is transported to the opposite side of the air guide frame 2112 with the conveying part 260, the wind entering the cooling box 210 through the air inlet 2111 and the air guide frame 2112 blows to the atomization heat exchange part 261; when the wind blows to the atomization heat exchange part 261, the flexible water absorbing part 2612 is in a horizontal state and parallel to the direction of the wind; the four adjacent flexible water absorbing parts 2612 form a cooling channel, and when the wind blows to the flexible water absorbing part 2612, the water in the flexible water absorbing part 2612 is blown to form water mist in the cooling channel, so that the flowing air is heat exchanged.

[0069] S3, the flexible water absorbing part 2612 moving above the air inlet 2111 rotates downward due to gravity, and is combed by the combing rod 243 when passing through the flexible combing part 240.

[0070] S4, when the combed flexible water absorbing part 2612 moves to the side opposite to the air inlet 2111, the flexible water absorbing part 2612 forms an adsorption layer on the movable belt 262 due to gravity, and the heat exchanged air with water mist passes through the adsorption layer and is adsorbed, and then enters the wireless communication base station cabinet 100, so as to cool the wireless communication base station cabinet 100.

[0071] Based on the disclosed cooling method, the complete cooling process and corresponding technical effects of the cooling system are as follows:

[0072] The heat dissipation exhaust fan 110 exhausts the air in the wireless communication base station cabinet 100, so that the inside of the wireless communication base station cabinet 100 is in a negative pressure state, and therefore the external air enters the wireless communication base station cabinet 100 through the cooling device 200, and the air can be dusted and cooled through the cooling device 200, and after entering the wireless communication base station cabinet 100, the inside of the wireless communication base station cabinet 100 can be cooled and cooled down.

[0073] Specifically,

[0074] The air enters the cooling box 210 through the air inlet 2111 and the air guide frame 2112, and due to the arrangement of the air guide frame 2112, the air flows more concentratedly.

[0075] The motor 220 starts to work, and the motor 220 drives the short pipe 232 and the first belt pulley 231 to rotate, as shown in Figure 8 , counterclockwise rotation; the second belt pulley 235 is driven to rotate under the transmission of the transmission belt 233, and since the two second belt pulleys 235 are connected through the long pipe 234, the other second belt pulley 235 is driven to rotate, and the other first belt pulley 231 is driven to rotate through the transmission of the transmission belt 233 thereon, so that the two first belt pulleys 231 and the two second belt pulleys 235 are synchronously rotated; the two transmission belts 233 can drive the movable belt 262 to rotate.

[0076] The air guide frame 2112 makes the air blow to the movable belt 262, and the air blows to the movable belt 262 and then blows to the atomizing heat exchange part 261 through the movable belt 262, and the movable belt 262 can filter impurities in the air to realize the first filtering treatment of the air.

[0077] When the air blows to the atomizing heat exchange part 261, the wet flexible water-absorbing part 2612 is blown from the original state of being attached to the movable belt 262 to a horizontal state, i.e., parallel to the direction of air flow, and the air blows to the flexible water-absorbing part 2612 to blow off the water on the flexible water-absorbing part 2612 to complete the dehydration treatment of the flexible water-absorbing part 2612; it should be noted that the dehydration here only removes the water on the flexible water-absorbing part 2612, and is not drying.

[0078] The water on the flexible water-absorbing part 2612 is blown off to form water mist, and the flexible water-absorbing part 2612 in the area of the air guide frame 2112 is in a horizontal state, and the four adjacent flexible water-absorbing parts 2612 form an atomizing cooling channel, and the water mist evaporates to absorb heat in the air, so that the air can be heat exchanged and cooled; since the flexible water-absorbing part 2612 changes from a nearly vertical state to a horizontal state, the time and path of air heat exchange are greatly increased, so that the air heat exchange effect is better.

[0079] It needs to be noted that when the flexible water absorption member 2612 is separated from the clean water, the clean water absorbed by the flexible water absorption member 2612 is partially separated from the flexible water absorption member 2612 due to gravity, so that the wind force for changing the flexible water absorption member 2612 from the approximately vertical state to the horizontal state is greatly reduced, and the air concentrated by the air guide frame 2112 is blown to the flexible water absorption member 2612, so that the flexible water absorption member 2612 can be changed from the approximately vertical state to the horizontal state.

[0080] When the flexible water absorption member 2612 moves to the upper side of the air guide frame 2112, the flexible water absorption member 2612 is no longer affected by the flowing air. Since the flexible water absorption member 2612 is in a wet state, it is reset by falling again due to gravity.

[0081] With the continuous movement of the movable belt 262, the flexible water absorption member 2612 passing through the air guide frame 2112 moves to the upper flexible carding part 240. Due to the guidance of the first pulley 231, the flexible water absorption member 2612 in this part is in a vertical state and gradually approaches the carding rod 243. If the adjacent flexible water absorption member 2612 is knotted, the part will be hung on the carding rod 243 and drive the carding rod 243 and the movable rod 242 to rotate, and finally the two are separated, which will not affect the normal operation of the equipment. The process will drive the encoder to rotate. The encoder is an incremental encoder, which calculates the rotation angle by outputting the number of pulses and needs initial positioning, which has low cost. The reset of the movable rod 242 is realized under the action of the torsional spring, so that the initial positioning of the encoder is satisfied without external intervention.

[0082] If there is no knot, the carding rod 243 and the movable rod 242 will not rotate. The carding rod 243 can card the flexible water absorption member 2612. When the flexible water absorption member 2612 rotates to the other side, the flexible water absorption member 2612 will overlap to form an adsorption layer.

[0083] It needs to be noted that the rotation angle measuring instrument 241 rotates and counts. If the number of rotations is greater than the set value, an alarm can be connected to remind the staff to handle the knotted part, so as to ensure the stable operation of the cooling device.

[0084] If it is only a simple winding, the wound flexible water absorption member 2612 can be carded by the carding rod 243 to separate it for subsequent use, so as to ensure the cooling quality.

[0085] The air in the atomizing cooling channel flows to the communication port 2113, blows to the treated and dehydrated flexible water absorption member 2612, and the water mist in the flowing air can be adsorbed by the overlapped flexible water absorption member 2612. The air without water mist flows to the wireless communication base station cabinet 100 through the communication port 2113 and flows upward to be discharged, so that the environment in the wireless communication base station cabinet 100 can be cooled and cooled.

[0086] Due to the air into the cooling device 200, the air can be humidified by the atomized cooling channel, avoiding dry air into the wireless communication base station cabinet 100, so that the wireless communication base station cabinet 100 is easy to produce static electricity; at the same time, the use of stacked flexible water absorption element 2612 can process water mist, avoid air too humid affect the electrical work; the humidity is 40%-60% more appropriate, neither easy to produce static electricity, nor easy to condensation.

[0087] Among them, the stacked flexible water absorption element 2612 is also a secondary heat exchange structure, the heat exchange air is blown through the humid air, and the water evaporation heat absorption can cool the air again; the secondary cooling air is blown into the wireless communication base station cabinet 100, further improving the cooling effect.

[0088] It should be noted that due to the secondary heat exchange structure of this part is treated by dehydration and the wind speed is relatively reduced, so it will not cause the secondary heat exchange structure to blow into the wireless communication base station cabinet 100, and will not affect the equipment inside the wireless communication base station cabinet 100.

[0089] The secondary heat exchange structure follows the activity belt 262 to move down and finally moves into the clean water, which can re-wet the flexible water absorption element 2612 to cool the air for the next time.

[0090] The above, only for the preferred specific embodiments of the present application, but the protection scope of the present application is not limited to this, any skilled in the art of the technical personnel in the technical range disclosed by the present application, according to the technical scheme of the present application and the invention concept of the invention, equivalent replacement or change, should be covered in the protection scope of the present application.
