Abstract

A tube tower and a base station. The tube tower comprises a tower wall. A first ventilation hole for taking in air and a second ventilation hole for discharging air are formed in the tower wall. The tower wall defines an internal space in a surrounding manner. At least two device compartments that are vertically disposed and separated from each other and that are used for accommodating devices are disposed in the internal space, and at least one device compartment is provided with a ventilation device. An air intake channel is formed between an air inlet of the ventilation device and a corresponding first ventilation hole, and an air discharge channel is formed between an air outlet of the ventilation device. The air intake channel is isolated from the other device compartments and/or the air discharge channel is isolated from the other device compartments. In this way, hot air generated by a device in a device compartment does not enter an air intake channel of another device compartment through the internal space of the tube tower, so that it is ensured that all devices in the device compartments have good heat dissipation effect.

Description

TUBE TOWER AND BASE STATION [0001] The present application claims priority to Chinese Patent Application No. 201720156153.4, entitled Towers and Base Stations, filed on February 21, 2017, the entire contents of which are hereby incorporated by reference in its entirety.

TECHNICAL FIELD [0001] This disclosure relates to the field of communications device installation technologies, and in particular, to a tube tower and a base station.

BACKGROUND [0002] Development of mobile communication services brings a large demand for communication sites. For various reasons, it is extremely difficult to obtain a conventional site that occupies a large area. Therefore, suppliers of base station devices work on a base station design to reduce a footprint.

[0003] At present, a popular base station design solution for reducing a footprint is to combine a base station and a tower, that is, to install a base station inside a tube tower, so as to significantly reduce a footprint. However, for such a design, problems such as heat dissipation and waterproofing of the base station need to be resolved.

[0004] A tube tower base station in the prior art is shown in FIG. 1, and includes a bottom tube tower 101, an upper tube tower 102, and an antenna 103. A maintenance door 104 that can be opened is disposed on a tower wall of the bottom tube tower 101. Various devices 108 used for implementing communication are placed inside the tower. Air intake holes 105 are disposed on a lower part of the bottom tube tower 101, air exhaust holes 106 are disposed on an upper part of the bottom tube tower 101, and an axial flow fan 107 is disposed inside the tower. Driven by the axial flow fan 107, outside air enters the tower from the air intake holes 105 on the lower part, and inside air (an air current) is exhausted from the air exhaust holes 106 on the upper part, so as to cool the devices 108. FIG. 1 further shows internal circuits 109.

[0005] The prior art has at least the following problems:

[0006] 1. Cool air passes through devices at an upper layer from devices at a lower layer, and then is exhausted; consequently, a temperature of air reaching the devices at the upper layer is excessively high, the devices at the upper layer cannot be effectively cooled, and an excessively hot breakdown is easy to occur.

[0007] 2. No protection measure is adopted for the devices in the tower, and the devices are likely to be badly eroded by salt fog. Therefore, complex waterproofing design needs to be conducted for both the air intake vent and the air exhaust vent of the tower. If sealing on a roof of the tube tower is not tight and water penetrates the tower, leaked water reaches the devices along a vertical ventilation path. For example, when maintenance or capacity expansion is being performed on a device, the sealing on the roof loses effectiveness because a maintenance engineer performs an operation such as dragging and shaking on an internal cable. Consequently, the devices are wetted by rain, and an accident of short circuit and a failure of the devices occurs.

SUMMARY [0008] In view of this, embodiments of this disclosure provide a tube tower and a base station, to ensure that heat generated by ventilation and heat dissipation in a lower equipment compartment does not affect a device in an upper equipment compartment. The technical solution is as follows:

[0009] According to a first aspect, a tube tower is provided, a first breather hole used for air intake and a second breather hole used for air exhaust are disposed on a tower wall of the tube tower, interior space is enclosed by the tower wall, at least two equipment compartments that are separated in a vertical direction and are used to hold devices are disposed in the interior space, a ventilation apparatus is disposed in at least one equipment compartment, an air intake vent of the ventilation apparatus and a corresponding first breather hole form an air intake channel, an air exhaust vent of the ventilation apparatus and a corresponding second breather hole form an air exhaust channel, and the air intake channel is isolated from another equipment compartment and/or the air exhaust channel is isolated from another equipment compartment.

[0010] In this embodiment of this disclosure, the tube tower includes equipment compartments that are separated in a vertical direction, and ventilation apparatuses are disposed in the equipment compartments to speed up ventilation, so that devices can be better cooled. In addition, an air intake channel in each equipment compartment is isolated from another equipment compartment and/or an air exhaust channel is isolated from another equipment compartment, that is, an air current entering each equipment compartment directly comes from the outside of the tube tower or an exhausted air current directly goes to the outside of the tube tower, so that heat generated by a device in each equipment compartment is released to the outside of the tube tower along a heat dissipating path in the equipment compartment, and hot wind generated by heat dissipation for a device in each equipment compartment does not enter an air intake channel in another equipment compartment through interior space in the tube tower. Therefore, each equipment compartment has a relatively independent heat dissipating channel, and heat dissipation in a lower equipment compartment does not affect heat dissipation in an upper equipment compartment, thereby avoiding a situation, in the prior art, in which heat generated by a device in a lower equipment compartment enters an upper equipment compartment through a heat dissipating channel because the heat dissipating channel is a vertical heat dissipating channel that is penetrable from the bottom to the top and passes through all equipment compartments.

[0011] In a first possible implementation manner of the first aspect, the first breather hole and the second breather hole are located on two opposite sides of the tower wall.

[0012] Because a first breather hole used for air intake and a second breather hole used for air exhaust are located on two opposite sides of the tower wall, a front side and a rear side of the equipment compartment are respectively used for air intake and air exhaust, a heat dissipation path is reasonable, and it can be avoided that a part in the equipment compartment is excessively hot.

[0013] Optionally, height ranges of a first breather hole and a second breather hole that are corresponding to a same equipment compartment are within a height range of the equipment compartment.

[0014] In this way, the breather holes that are used for air intake and air exhaust are corresponding to the equipment compartment in terms of height, it is convenient for air intake and air exhaust, and heat dissipation efficiency is improved.

[0015] Further, height ranges of a first breather hole and a second breather hole that are corresponding to a same equipment compartment are within a height range of a lower part of the equipment compartment, and a ventilation apparatus in the equipment compartment is disposed in an upper part of the equipment compartment.

[0016] In this way, an air current used for heat dissipation enters from a lower part of the equipment compartment, then comes to the ventilation apparatus in the upper part of the equipment compartment, and finally goes out from a lower part of the equipment compartment, so that a heat dissipation path in the equipment compartment is relatively long, and heat dissipation is performed more comprehensively and evenly in the equipment compartment.

[0017] In a second possible implementation manner of the first aspect, a common vertical air intake channel or a common vertical air exhaust channel is disposed between the tower wall and the at least two equipment compartments.

[0018] In this way, an air intake breather hole (that is, a first breather hole) or an air exhaust breather hole (that is, a second breather hole) may be shared. In addition, heat dissipation in the equipment compartments still does not affect each other, and heat in an equipment compartment is not transferred to another equipment compartment through an air channel.

[0019] In a third possible implementation manner of the first aspect, a cabinet is disposed in at least one equipment compartment, and a device in the equipment compartment is installed in the cabinet.

[0020] In this way, because the cabinet has a protection function, outside moisture or pollutants can be prevented from affecting the device in the equipment compartment.

[0021] Optionally, the ventilation apparatus is installed in the cabinet.

[0022] In this way, heat dissipating channels in equipment compartments that are adjacent in a vertical direction are further isolated by using cabinets, and a ventilation apparatus installed in a cabinet can perform heat dissipation for a device in the cabinet more effectively.

[0023] Optionally, the ventilation apparatus is installed in an upper part of the cabinet, and the air intake channel in the equipment compartment passes through a lower portion the device in the cabinet.

[0024] In this way, an air current from the air intake channel in the cabinet passes through the device in the cabinet from the bottom to the top, and then reaches the ventilation apparatus in the upper part, so that heat generated by the device can be taken away more effectively.

[0025] Optionally, a protection level of each cabinet is equal to or greater than a protection level required by a device installed in the cabinet.

[0026] Because a protection level of a cabinet is equal to or greater than a protection level required by a device installed in the cabinet, the device can be effectively protected, and rain, dust, and salt fog can be prevented from damaging the device.

[0027] In a fourth possible implementation manner of the first aspect, a maintenance door is disposed on the tower wall, and the equipment compartments are located behind the maintenance door.

[0028] In this way, the maintenance door can be conveniently opened to install or dismantle a device in an equipment compartment.

[0029] Optionally, the first breather hole or the second breather hole is disposed on the maintenance door.

[0030] In this way, the breather hole is corresponding to the equipment compartment behind the maintenance door, so that ventilation and heat dissipation can be implemented more effectively.

[0031] Optionally, one or more equipment compartments are correspondingly disposed behind one maintenance door.

[0032] In this way, quantities and sizes of maintenance doors and equipment compartments can be flexibly set separately according to a size of a device and/or another requirement. This improves flexibility of arrangement in a tube tower.

[0033] In a fifth possible implementation manner of the first aspect, the ventilation apparatus includes a fan.

[0034] A fan is a ventilation apparatus that is easy to manufacture, install, and use and has high efficiency. Therefore, costs for manufacturing and using the tube tower can be reduced.

[0035] Optionally, the fan is a centrifugal fan and includes a case on which the air exhaust vent is disposed.

[0036] In this way, air can enter from an axial direction of the fan, and then goes to a rear side.

[0037] In a sixth possible implementation manner of the first aspect, the tube tower further includes an air exhaust window, where an air intake vent of the air exhaust window is interconnected with the air exhaust vent of the ventilation apparatus, and an air exhaust vent of the air exhaust window abuts against the tower wall and is connected to a corresponding second breather hole.

[0038] In this way, an air exhaust channel in each equipment compartment forms a closed path, and hot wind is directly exhausted from the second breather hole, and does not affect heat dissipation of a device in another equipment compartment.

[0039] According to a second aspect, a base station is provided, including the tube tower in the first aspect and an antenna disposed on the tube tower.

[0040] In this embodiment of this disclosure, the base station uses the tube tower in the first aspect. The tube tower includes equipment compartments that are separated in a vertical direction, and ventilation apparatuses are disposed in the equipment compartments to speed up ventilation, so that devices can be better cooled. In addition, an air intake channel in each equipment compartment is isolated from another equipment compartment and/or an air exhaust channel is isolated from another equipment compartment, that is, an air current entering each equipment compartment directly comes from the outside of the tube tower or an exhausted air current directly goes to the outside of the tube tower, so that heat generated by a device in each equipment compartment is released to the outside of the tube tower along a heat dissipating path in the equipment compartment, and hot wind generated by heat dissipation for a device in each equipment compartment does not enter an air intake channel in another equipment compartment through interior space in the tube tower. Therefore, each equipment compartment has a relatively independent heat dissipating channel, and heat dissipation in a lower equipment compartment does not affect heat dissipation in an upper equipment compartment, thereby avoiding a situation, in the prior art, in which heat generated by a device in a lower equipment compartment enters an upper equipment compartment through a heat dissipating channel because the heat dissipating channel is a vertical heat dissipating channel that is penetrable from the bottom to the top and passes through all equipment compartments. In this way, heat resistance and durability of the base station are improved. In addition, when the tube tower has the foregoing features, the base station also has the foregoing advantages brought by the foregoing features.

DESCRIPTION OF EMBODIMENTS [0055] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following further describes the implementation manners of this disclosure in detail with reference to the accompanying drawings.

[0056] A person skilled in the art should understand that the tube tower in this disclosure generally refers to a tube tower structure that is used in a tube tower base station and used for holding a device inside, but the tube tower in this disclosure is not limited to this and may also be a tube tower structure that is applied on another occasion and used for holding a device inside.

The expressions such as upper, lower, and height are used on the premise that the tube tower is in a vertical state after installation. The horizontal panel in this disclosure refers to a panel structure whose panel surface is in a horizontal or approximately horizontal state after the tube tower is installed vertically. However, the panel surface of the horizontal panel is not limited to be absolutely horizontal or smooth. An upper part or a lower part of an object described in this disclosure refers to a position of an upper half or a lower half of the object. A position above or below an object described in this disclosure refers to a position that is above or below the object and outside the object. Front and rear described in this disclosure are relative by using the figure as a reference, but positions thereof are not strictly limited, provided that the positions roughly meet a condition. The word corresponding in this disclosure refers to be cooperative for jointly implementing a function between corresponding objects or be corresponding in position, and a person skilled in the art may determine a meaning of corresponding according to a scenario.

[0057] FIG. 2a and FIG 2b are stereoscopic views of a tube tower according to an embodiment of the present application, FIG 3 is a stereoscopic decomposition view of the tube tower, and a device in an equipment compartment is shown outside the tube tower. As shown in FIG. 2a, FIG 2b, and FIG 3, the tube tower provided in this embodiment includes a tower wall 1, the tower wall 1 may be made of appropriate housing materials, and the tower wall 1 forms a main shape that can be seen outside the tube tower.

[0058] As shown in FIG 2a and FIG 2b, breather holes are disposed on the tower wall 1, and include multiple first breather holes 21 used for air intake and multiple second breather holes 22 used for air exhaust. Air inside the tower wall 1 and air outside the tower wall 1 are exchanged through the breather holes. The first breather holes 21 and the second breather holes 22 are main means for exhausting heat. A shape of the breather hole may be round, as shown in the figure, and multiple breather holes are arranged in a centralized manner in a rectangular area. The breather hole may have another appropriate shape, or may be arranged in another appropriate manner.

[0059] As shown in FIG. 3, interior space is enclosed by the tower wall 1. Multiple equipment compartments 4 that are used to hold devices 3 are disposed in the interior space, and a horizontal panel 6 is disposed between every two equipment compartments 4 that are adjacent in a vertical direction. These devices 3 may be selected and used according to a requirement, for example, devices for implementing a communication function are selected. According to a requirement, ventilation apparatuses, that is, fans 5, are disposed in some or all of the equipment compartments 4, but for an equipment compartment 4 used for installing a device that generates low heat and has good heat resistance, the ventilation apparatus may not be installed in the equipment compartment 4.

[0060] An air intake vent of a fan 5 and a first breather hole 21 form an air intake channel, an air exhaust vent of a fan 5 and a second breather hole 22 form an air exhaust channel, and the air intake channel is isolated from another equipment compartment and/or the air exhaust channel is isolated from another equipment compartment. The isolation herein means that all or most of air entering an air intake channel does not come from another equipment compartment, or all or most of air currents getting out from an air exhaust channel do not enter another equipment compartment. A person skilled in the art should understand that the isolation may be implemented by closing, relative to another equipment compartment, an air intake channel or an air exhaust channel in each equipment compartment in the tube tower, or closing the equipment compartments, or the like.

[0061] In this embodiment, the tube tower includes equipment compartments that are separated in a vertical direction, and ventilation apparatuses are disposed in the equipment compartments to speed up ventilation, so that devices can be better cooled. In addition, an air intake channel in each equipment compartment is isolated from another equipment compartment and/or an air exhaust channel is isolated from another equipment compartment, that is, an air current entering each equipment compartment directly comes from the outside of the tube tower or an exhausted air current directly goes to the outside of the tube tower, so that heat generated by a device in each equipment compartment is released to the outside of the tube tower along a heat dissipating path in the equipment compartment, and hot wind generated by heat dissipation for a device in each equipment compartment does not enter an air intake channel in another equipment compartment through interior space in the tube tower. Therefore, each equipment compartment has a relatively independent heat dissipating channel, and heat dissipation in a lower equipment compartment does not affect heat dissipation in an upper equipment compartment, thereby avoiding a situation, in the prior art, in which heat generated by a device in a lower equipment compartment enters an upper equipment compartment through a heat dissipating channel because the heat dissipating channel is a vertical heat dissipating channel that is penetrable from the bottom to the top and passes through all equipment compartments.

[0062] In this embodiment, as shown in FIG. 2a, a first breather hole 21 and a second breather hole 22 may be located on two opposite sides of the tower wall 1. Because in such a design, a first breather hole used for air intake and a second breather hole used for air exhaust are located on two opposite sides of the tower wall 1, a front side and a rear side of the equipment compartment 4 are respectively used for air intake and air exhaust, a heat dissipation path is reasonable, and it can be avoided that a part in the equipment compartment 4 is excessively hot.

[0063] Height ranges of a first breather hole 21 and a second breather hole 22 that are corresponding to a same equipment compartment 4 need to be within a height range of the equipment compartment 4, so that the first breather hole 21 and the second breather hole 22 are corresponding to the equipment compartment 4 in terms of height, it is convenient for air intake and air exhaust, and heat dissipation efficiency is improved. It should be understood that in some possible designs, height ranges of a first breather hole 21 and a second breather hole 22 that are corresponding to a same equipment compartment 4 may not be within a range of the equipment compartment 4, and this shall also fall within the scope of protection defined by this disclosure.

[0064] In addition, height ranges of a first breather hole 21 and a second breather hole 22 that are corresponding to a same equipment compartment 4 may be within a height range of a lower part of the equipment compartment 4, that is, positions of the io first breather hole 21 and the second breather hole 22 are lower, and a ventilation apparatus in the equipment compartment 4 may be disposed in an upper part of the equipment compartment 4. In this way, an air current used for heat dissipation enters from a side on a lower part of the equipment compartment 4, then comes to the ventilation apparatus in the upper part of the equipment compartment 4, and finally goes out from another side on a lower part of the equipment compartment 4, so that a heat dissipation path in the equipment compartment 4 is relatively long, and heat dissipation is performed more comprehensively and evenly in the equipment compartment.

[0065] As shown in FIG. 3, a cabinet 7 is disposed in each equipment compartment 4, and a device 3 in the equipment compartment 4 is installed in the cabinet 7. The cabinet 7 has a protection function, and can prevent outside moisture or pollutants from affecting the device 3 in the equipment compartment 4. The cabinet 7 may be a cuboid or another proper shape, and may be provided, according to a requirement, with a cabinet door 71 that can be opened. A protection level of each cabinet 7 is equal to or greater than a protection level required by a device 3 installed in the cabinet 7. The device 3 installed in the cabinet 7 may be a device that needs to be loaded or has been loaded. The required protection level is the highest protection level required by the device installed in the cabinet, and can effectively protect the device 3 and prevent rain, dust, and salt fog from damaging the device 3. For example, a protection level of the cabinet 7 may be IP55, the first 5 in IP55 represents that dust can be prevented from intrusion, and the second 5 represents that sprayed water can be prevented from intrusion. Therefore, at this protection level, rain, dust, and salt fog can be prevented from damaging the device 3, and there is no need to conduct complex waterproofing design for breather holes and a roof of the tube tower like the prior art. When a cabinet 7 exists, the fan 5 may be installed in the cabinet 7, for example, located in an upper part of the cabinet 7 and fixed by using a top panel of the cabinet 7 or a support structure disposed in the cabinet.

[0066] As shown in FIG. 3, a fan 5 is installed in an upper part of a cabinet 7, and an air intake channel in an equipment compartment 4 passes through a lower portion a device 3 in the cabinet 7, that is, the fan 5 is located in an upper part of the cabinet 7, the device 3 is located in a middle part of the cabinet 7, and the air intake channel is located in a lower part of the cabinet 7. Because an air current passes through the device in the cabinet from the bottom to the top, and then reaches the fan 5 in the upper part, heat generated by the device 3 can be taken away more effectively.

[0067] In this embodiment, a fan 5 is used as a ventilation apparatus. A fan is a ventilation apparatus that is easy to manufacture, install, and use and has high efficiency. Therefore, costs for manufacturing and using the tube tower can be reduced. However, another proper type of ventilation apparatus, such as an extraction pump, may also be used in another implementation manner of this disclosure. Preferably, the fan 5 in this embodiment is a centrifugal fan and includes a case on which an air exhaust vent is disposed, that is, places, except the air exhaust vent, in a radial direction of the fan 5 are wrapped up in the case. In this way, air can enter from an axial direction of the fan, and then goes to a rear side. For example, the fan 5 is installed in an upper part of the cabinet 7, an air current passes through the device from a lower part of the cabinet 7, moves upward to an axial-direction air intake vent of the fan 5, then goes out from the air exhaust vent of the case, and finally is exhausted to the outside of the tube tower from the second breather hole 22 on the tube tower 1. Such a ventilation path can take away heat of the device 3 more effectively. It should be understood that although the fan 5 in this embodiment is installed in an upper part of the cabinet 7 or the equipment compartment 4, in some possible designs, the fan 5 may also be installed in a lower part or another position of the cabinet or the equipment compartment according to a specific situation, provided that the fan can implement a ventilation function, and this shall also fall within the scope of protection defined by this disclosure.

[0068] Although each equipment compartment 4 shown in FIG. 3 is provided with a cabinet 7, for a device 3 that has a high protection level, for example, an RRU (Radio Remote Unit, radio remote unit) device whose protection level is IP55, an equipment compartment 4 in which the device 3 is located may not be provided with a cabinet, because the device 3 can implement functions of dustproof, waterproof, and salt fog-proof. For other devices 3 having low protection requirements, equipment compartments 4 in which these devices 3 are located may not be provided with cabinets.

[0069] As shown in FIG. 3, a maintenance door 8 is disposed on the tower wall 1, and the equipment compartments 4 are located behind the maintenance door 8, so that the maintenance door 8 can be conveniently opened to install or dismantle a device 3 in an equipment compartment 4. The second breather hole 22 may be disposed on the maintenance door 8. In other implementation manners, the first breather hole 21 may also be disposed on the maintenance door 8. In this way, the breather hole is corresponding to the equipment compartment 4 behind the maintenance door 8, so that ventilation and heat dissipation can be implemented more effectively. In FIG. 3, one maintenance door 8 is corresponding to two equipment compartments 4, but this disclosure is not limited thereto. One or more equipment compartments 4 may be correspondingly disposed behind one maintenance door 8 according to a requirement, that is, quantities and sizes of maintenance doors 8 and equipment compartments 4 can be flexibly set separately according to a size of a device 3 and/or another requirement. This improves flexibility of arrangement in a tube tower.

[0070] As shown in FIG. 3, the equipment compartments 4 may further include air exhaust windows 72. The air exhaust window 72 may be a case apparatus that includes an air intake vent and an air exhaust vent. FIG. 4a shows a cross section of a tube tower in which assembling is completed. FIG. 4b shows a cross section of an equipment compartment (that is, a part enclosed by a dotted line in FIG. 4a) in which assembling is completed. It can be clearly seen from FIG. 4b that an air intake vent of an air exhaust window 72 is interconnected with an air exhaust vent of a fan 5, and an air exhaust vent of the air exhaust window 72 abuts against the tower wall 1 and is connected to a corresponding second breather hole 22. In this way, for each equipment compartment 4, an air current enters from a first breather hole 21 on a left side, goes up in a cabinet 7, reaches an air intake vent of the fan 5, then enters the air intake vent of the air exhaust window 72 from an air exhaust vent of the fan 5, then goes down to the air exhaust vent of the air exhaust window 72, and finally is exhausted from the second breather hole 22. In FIG. 4, the air exhaust window 72 is tightly attached to a back wall of the cabinet 7. Actually, the air exhaust window 72 may be installed independent of the cabinet 7; or the air exhaust window 72 may be not needed, and the air exhaust vent of the fan 5 is interconnected with the second breather hole 22 on the tube wall 1 in a direct manner or by using a pipe. In this way, an air exhaust channel in each equipment compartment 4 forms a closed path, and hot wind is directly exhausted from the second breather hole 22, and does not affect heat dissipation of a device 3 in another equipment compartment 4.

[0071] FIG. 5 schematically shows air channels of equipment compartments in a tube tower. As shown in FIG. 5, an air current enters from a lower part on a left side of the tower wall 1, driven by a fan 5, the air current goes upward and passes through a device 3 in an equipment compartment 4, then reaches an air intake axial surface (that is, an air intake vent) of the fan 5, then goes out from a right side of the fan 5, and finally goes down along a right side of the tower wall 1 and goes to the outside. A path along which the air current moves is similar to a Ω shape, as shown in the line with an arrow in the figure. It should be noted that the left side and the right side herein are directions in the figure.

[0072] In FIG. 5, the equipment compartments 4 are corresponding to different breather holes on the tower wall 1. However, in a variant embodiment different from this embodiment, a first breather hole 21 (also referred to as an air intake breather hole) or a second breather hole 22 (also referred to as an air exhaust breather hole) on the tower wall 1 may also be shared. FIG. 6 and FIG. 7 respectively show examples of a common air intake breather hole and a common air exhaust breather hole. In FIG. 6, a common vertical air intake channel 9 is formed between the tower wall and the equipment compartments. In FIG. 7, a common vertical air exhaust channel 10 is formed between the tower wall and the equipment compartments. When there is a common vertical air intake channel 9, all air intake breather holes on the tower wall may be gathered in an area, and after an air current enters from a first breather hole, the air current reaches the equipment compartments through the vertical air intake channel. When there is a common vertical air exhaust channel 10, all air exhaust breather holes on the tower wall may be gathered in an area, and after air currents come out from the equipment compartments, the air currents reach a second breather hole through the vertical air exhaust channel. In this way, an air intake breather hole or an air exhaust breather hole may be shared, that is, disposition of an air intake breather hole or an air exhaust breather hole is simplified. In addition, heat dissipation in the equipment compartments still does not affect each other, and heat in an equipment compartment is not transferred to another equipment compartment through an air channel.

[0073] FIG. 8a, FIG. 8b, and FIG. 9 show a base station according to another embodiment of this disclosure, and the base station includes the tube tower provided in the foregoing embodiment and an antenna 11 disposed on the tube tower. To enable the antenna to reach a specific height, in addition to a bottom tube tower 12 in which an equipment compartment is disposed, a tube tower further includes an upper tube tower 13 disposed above the lower tube tower, and the antenna 11 is disposed on the upper tube tower 13. A person skilled in the art should understand that the tube tower in the base station is further provided with a power supply circuit and a signal circuit, although they are not shown in the figure, and at least some signal circuits pass through the upper tube tower 13 from the bottom tube tower 12, and are connected to the antenna 11. At the bottom of the tube tower, a fixing and installation structure, for example, an underpan with screw holes, may be included, so that the base station can be fixed in a plane by using screws.

[0074] In this embodiment, the base station uses the tube tower in the foregoing embodiment. The tube tower includes equipment compartments that are separated in a vertical direction, and ventilation apparatuses are disposed in the equipment compartments to speed up ventilation, so that devices can be better cooled. In addition, an air intake channel in each equipment compartment is isolated from another equipment compartment and/or an air exhaust channel is isolated from another equipment compartment, that is, an air current entering each equipment compartment directly comes from the outside of the tube tower or an exhausted air current directly goes to the outside of the tube tower, so that heat generated by a device in each equipment compartment is released to the outside of the tube tower along a heat dissipating path in the equipment compartment, and hot wind generated by heat dissipation for a device in each equipment compartment does not enter an air intake channel in another equipment compartment through interior space in the tube tower. Therefore, each equipment compartment has a relatively independent heat dissipating channel, and heat dissipation in a lower equipment compartment does not affect heat dissipation in an upper equipment compartment, thereby avoiding a situation, in the prior art, in which heat generated by a device in a lower equipment compartment enters an upper equipment compartment through a heat dissipating channel because the heat dissipating channel is a vertical heat dissipating channel that is penetrable from the bottom to the top and passes through all equipment compartments. In this way, heat resistance and durability of the base station are improved. In addition, when the tube tower has the foregoing features, the base station also has the foregoing advantages correspondingly brought by the foregoing features, and details are not described herein.

[0075] The foregoing descriptions are merely example embodiments of this disclosure, but are not intended to limit this disclosure. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of this disclosure should fall within the protection scope of this disclosure.
