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 accumulates 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 flow 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 normal, which is not conducive to 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 being not ideal.

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

[0015] Preferably, the flexible combing part comprises a movable rod arranged through the first pulley, an 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 absorption members on the connecting strip, the combing rods and the flexible water absorption members are staggered, end portions of the movable rod are rotatably installed on the inner side wall of the cooling box through torsional springs, and the end portions of the movable rod are connected with a rotation angle measuring instrument for detecting a rotation angle of the movable rod.

[0016] The application further discloses a cooling method of a wireless communication base station. 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 atomized heat exchange parts are sequentially immersed; S2, when the atomized heat exchange parts after being immersed are transported to the opposite side of the air guide frame by the conveying part, air in the cooling box blows to the atomized heat exchange parts through the air inlet and the air guide frame; when the air blows to the atomized heat exchange parts, the flexible water absorption members are in a horizontal state and parallel to the blowing direction; four adjacent flexible water absorption members form a cooling channel, and when the air blows to the flexible water absorption members, the water in the flexible water absorption members is blown and scattered in the cooling channel to generate water mist, and the flowing air is heat exchanged; S3, the flexible water absorption members moving above the air inlet rotate downward due to gravity, and the flexible water absorption members are combed by the combing rods when passing through the flexible combing part; S4, when the combed flexible water absorption members move to the side opposite to the air inlet, the flexible water absorption members form an adsorption layer on the movable belt due to gravity, and the heat exchanged air with the water mist contacts and adsorbs 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.

[0017] Compared with the prior art, the application has the following beneficial effects: 1. When the air blows to the atomized heat exchange parts, the flexible water absorption members originally adhered to the movable belt are blown to a horizontal state, four adjacent flexible water absorption members 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, improve the heat exchange effect, and solve the problem of unsatisfactory cooling effect caused by short air heat exchange flow channel and short heat exchange time in the prior art.

[0018] 2. The conveying part circulates to immerse the atomized heat exchange parts, and when the external air enters, the air blows to the conveying part and the atomized heat exchange parts, so that the water in the atomized heat exchange parts is blown and scattered to generate water mist, the air is heat exchanged and cooled in the atomized cooling channel, the air temperature entering the base station cabinet is effectively reduced, and the problem that the high-temperature inhaled air is not conducive to the heat dissipation of the base station device is overcome.

[0019] 3. The cooling device cools the air entering the wireless communication base station cabinet twice through the misting heat exchange and secondary heat exchange structure.

[0020] 4. The movable belt is made of nylon mesh cloth, which has a filtering effect on dust in the air while ensuring the air entering, and can purify the air entering the base station cabinet.

[0021] 5. The flexible combing part can comb each misting heat exchange part. If the adjacent flexible water absorbing elements are knotted, the combing rod and the movable rod will be rotated, the rotation angle measuring instrument will count the number of rotations, and when the number of rotations is greater than the set value, the alarm will alarm to remind the staff to handle the knotted part, ensuring the stable operation of the whole cooling device. If it is only a simple winding, the flexible water absorbing elements can be combed by the combing rod to separate them for subsequent use, thereby ensuring the cooling quality.

[0022] 6. The cleaning mechanism drives the rotating shaft and the long pipe to rotate synchronously with a speed difference through the synchronous belt drive, and can clean the surface of the movable belt by using the cleaning brush fixed on the rotating shaft, thereby ensuring the ventilation effect, better filtering the air, and reducing the influence of dust and other impurities on the cooling device and the base station cabinet.

[0023] 7.

The cooling system structure of the present application is simpler, the air heat exchange effect is better, and the equipment cost and maintenance difficulty are reduced.

[0024] In summary, when the air blows to the misting heat exchange part, the wet flexible water absorbing elements are blown from the original state of being attached to the movable belt to the horizontal state, and the adjacent four flexible water absorbing elements form a misting cooling channel, greatly increasing the air heat exchange time and path. At the same time, the water mist evaporates and absorbs the heat in the air to cool and heat exchange the air, thereby improving the heat exchange effect and solving the problem of unsatisfactory cooling effect caused by the short air heat exchange flow channel and short heat exchange time in the prior art.

DETAILED DESCRIPTION

[0027] 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 part of the embodiments of the present application, not all.

[0028] Reference Figures 1-14 A wireless communication base station cooling system, comprising 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, and a heat dissipation exhaust fan 110 installed on the top of the wireless communication base station cabinet 100, which can exhaust heat inside the wireless communication base station cabinet 100, and air outside 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 of the cooling device 200. The cooling device 200 comprises 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, and the atomization heat exchange parts 261 can be wetted when the conveying part 260 circulates and moves; when the air outside enters the wireless communication base station cabinet 100 through the cooling device 200, the air blows to the conveying part 260 and the atomization heat exchange parts 261 and scatters the water inside the atomization heat exchange parts 261 to generate water mist, and the atomization heat exchange parts 261 are dehydrated. The atomization heat exchange parts 261 deflected by the air flow are parallel to the direction of the air flow, a plurality of cooling channels are formed in communication and atomization between the adjacent two atomization heat exchange parts 261, and the air enters the atomized cooling channels for heat exchange and cooling; the atomization heat exchange parts 261 are stacked in a head-to-tail manner on the inner surface of the conveying part 260 due to gravity after being separated from the air, forming a secondary heat exchange structure, and the air passes through the secondary heat exchange structure for heat exchange and then enters the wireless communication base station cabinet 100.

[0029] As Figure 3 , Figure 4As shown, the cooling device 200 further comprises a cooling box 210 arranged outside the wireless communication base station cabinet 100, and 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 are not in contact to avoid abrasion or damage.

[0030] As shown in Figure 4 , Figure 5 , Figure 6 As shown, 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 the air to enter while having a filtering effect on 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 part 230 can move the movable belt 262 when rotating; the cooling box 210 is filled with clean water with a liquid surface above the lower transmission part 230, and the clean water is used to wet the atomization heat exchange part 261.

[0031] As shown in Figure 12 , Figure 13 As shown, the atomization 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 absorbent 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; The flexible water absorbing element 2612 is linearly arrayed 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 two adjacent 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 other end is the tail 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.

[0032] 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 blows 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.

[0033] 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 wall of the first pulley 231 is fixed with a short pipe 232, and the short pipe 232 is rotatably installed on the inner 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. 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.

[0034] 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.

[0035] 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.

[0036] As Figure 10 indicated, the flexible combing part 240 includes 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.

[0037] 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; 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.

[0038] 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.

[0039] 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, and 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.

[0040] The application further discloses a cooling method of a wireless communication base station. 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; 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, and the flowing air is heat exchanged; 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; 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, to cool the wireless communication base station cabinet 100.

[0041] Based on the disclosed cooling method, in combination with the structure and function of each component of the cooling system, the complete cooling process and corresponding technical effects are as follows: 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, is dusted and cooled by the cooling device 200, and then cools the inside of the wireless communication base station cabinet 100. Specifically: Air enters the cooling box 210 through the air inlet 2111 and the air guide frame 2112. Due to the design of the air guide frame 2112, the air flows more concentratedly. Motor 220 starts working, and the operation of motor 220 drives short pipe 232 and first pulley 231 to rotate, such as Figure 8 As shown, the rotation is counterclockwise. The second pulley 235 rotates under the transmission of the drive belt 233. Since the two second pulleys 235 are connected by a long tube 234, the other second pulley 235 rotates. Through the transmission belt 233 on it, the other first pulley 231 rotates, thus achieving synchronous rotation of the two first pulleys 231 and the two second pulleys 235. The two drive belts 233 can drive the movable belt 262 to rotate. The air is directed to the movable belt 262 by the air guide frame 2112. After being directed to the movable belt 262, the air passes through the movable belt 262 and is blown towards the atomizing heat exchange section 261. Impurities in the air can be filtered through the movable belt 262, thus achieving the first step of air filtration.

[0042] When air blows toward the atomizing heat exchange section 261, the wetted flexible absorbent 2612 is blown from its original position on the movable belt 262 to a horizontal position, that is, parallel to the direction of air flow. When air blows toward the flexible absorbent 2612, it can blow off the water on the flexible absorbent 2612, thus completing the dehydration treatment of the flexible absorbent 2612. It should be noted that the dehydration here only removes the moisture on the flexible absorbent 2612, not dries it. Water detached from the flexible water-absorbing component 2612 by the blowing action forms a water mist. The flexible water-absorbing components 2612 located in the air guide frame 2112 area are all in a horizontal state. The four adjacent flexible water-absorbing components 2612 form an atomized cooling channel. The water mist evaporates and absorbs heat from the air, thereby cooling the air through heat exchange. Since the flexible water-absorbing component 2612 changes from an almost vertical state to a horizontal state, the time and path for air heat exchange are greatly increased, resulting in a better air heat exchange effect. It should be noted that when the flexible water-absorbing component 2612 is separated from the clean water, the clean water absorbed by it is partially separated from the flexible water-absorbing component 2612 due to gravity. This will greatly reduce the wind force when the flexible water-absorbing component 2612 changes from an approximately vertical state to a horizontal state. The air guide frame 2112 concentrates the air towards the flexible water-absorbing component 2612, thus ensuring that the flexible water-absorbing component 2612 changes from an approximately vertical state to a horizontal state. When the flexible absorbent 2612 moves above the air guide frame 2112, the flexible absorbent 2612 is no longer affected by the flowing air. Since the flexible absorbent 2612 is in a wet state, it falls back to its original position due to gravity.

[0043] With the moving of the activity belt 262, the flexible water absorbing element 2612 passing through the air guide frame 2112 moves to the upper flexible carding part 240, and due to the guidance of the first belt pulley 231, the flexible water absorbing element 2612 at this part is in a vertical state and gradually approaches the carding rod 243; if the adjacent flexible water absorbing element 2612 is knotted, the part will hang on the carding rod 243 and drive the carding 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; this process will drive the encoder to rotate, the encoder is an incremental encoder, the rotation angle is calculated by the number of output pulses, and initial positioning is required, 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, and external intervention is not required.

[0044] 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 absorbing element 2612; when the flexible water absorbing element 2612 rotates to the other side, the flexible water absorbing element 2612 will overlap to form an adsorption layer; It should be noted that the rotation angle measuring instrument 241 rotates and counts, and 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 entire cooling device.

[0045] If it is only a simple winding, the wound flexible water absorbing element 2612 can be carded by the carding rod 243 to separate it for subsequent use, thereby ensuring the cooling quality.

[0046] The air in the atomizing cooling channel flows towards the communication port 2113, and the air blows towards the treated and dehydrated flexible water absorbing element 2612. The water mist in the flowing air can be adsorbed by the stacked flexible water absorbing element 2612, and the air without water mist flows to the wireless communication base station cabinet 100 through the communication port 2113 and flows upwards to be discharged, so that the environment in the wireless communication base station cabinet 100 can be cooled.

[0047] Since the air enters the cooling device 200, the air can be humidified by the atomizing cooling channel, which avoids dry air entering the wireless communication base station cabinet 100, so that the wireless communication base station cabinet 100 is prone to static electricity; at the same time, the stacked flexible water absorbing element 2612 can process the water mist, which avoids that the air is too humid to affect the electrical work; the humidity of 40%-60% is more appropriate, which is neither easy to produce static electricity nor easy to condense.

[0048] The stacked flexible water absorbing element 2612 is also a secondary heat exchange structure, the air after heat exchange blows through the humid air, and the evaporation of water can cool the air again; the secondary cooled air blows into the wireless communication base station cabinet 100, which further improves the cooling effect.

[0049] It should be noted that, due to the secondary heat exchange structure of this part being subjected to dewatering treatment and the relative reduction of wind speed, blowing into the wireless communication base station cabinet 100 on the secondary heat exchange structure will not cause any impact on the equipment inside the wireless communication base station cabinet 100.

[0050] The secondary heat exchange structure is finally moved into clean water by following the downward movement of the movable belt 262, and the flexible water absorbing member 2612 can be subjected to re-wetting treatment through the clean water, so as to cool the air in the next heat exchange.

[0051] The above describes only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
