Description

" the outer self-loopa of buoyance chamber " cooling energy-saving device of small base station Cabinet

(1) technical field: the invention belongs to communication base station energy-conserving technical fields.

(2) background technique: in mobile communication technology field, with advances in technology, occur in recent years a kind of small-sized Outdoor " integrated communication base station " will form various fundamentals, the infrastructure equipment of base station, be subject to Deep integrating combination and Simplify design, is mounted in outdoor small-sized cabinet.It is needed and equipment situation, the small-sized room of an integrated base station according to task Outer cabinet is divided into the unit cabin that several (mostly three, also there is one, two or four) separate and connect each other again, And combine installing with antenna iron tower together.Most steel towers are fixedly mounted on ground, are also had steel tower and cabinet combination It is mounted on transportable pedestal.Past normal base station is all bigger, general occupied area all in more than ten square meters, and It is arranged on remoter a piece of biggish special ground or on the roof of building, nowadays the very narrow people in street roadside It is seen that many such small-sized integrated machine cabinet type communication base stations by trade.

The cabinet of integrated communication base station outdoors is placed, cabinet height is generally at 2 meters or so, the width of each unit cabin Degree and depth are generally at 1 meter or so.On the one hand, many electrical equipments placed inside outdoor cabinet, even relative energy-saving, hair Heat is small, can also generate heat in use, needs to radiate, to maintain the normal working temperature of equipment and electric appliance； On the other hand, being placed on outdoor cabinet also will receive the irradiation of the sun, the irradiation of the sun and summer higher temperature, can all increase Add the temperature of interior of equipment cabinet, so that being possible to inside cabinet more than the temperature upper limit allowed.Therefore it is asked for cabinet solution heat dissipation While topic, also to solve the problems, such as to prevent external heat from entering cabinet.General cabinet, which uses, is sandwiched between foam heat insulating material Double-layer metal plate heat insulation structural, carry out the entrance of sun-proof and anti-external heat；And radiating mode generallys use installation small air-conditioning system Heat dissipation temperature control is carried out, and the ventilation mode with strainer.Since the electrical equipment inside cabinet constantly works, Also heat will be constantly generated, needs to be continued for radiate.Therefore, either cooled down using air conditioner, or ventilation is changed Gas requires constantly to consume electric energy.And even with strainer, not only strainer needs are regularly maintained, but also ventilation Pollutant outside the cabinets such as dust can yet be brought into inside cabinet, be affected the normal operation of the equipment.

The present inventor is before proposing this innovative technology for small-sized integrated base station energy-saving, once to this novel base The status stood is surveyed and studied, and has been checked dozens of small base station, has been found unexpectedly, nowadays due to cannot normally dissipate Heat, the cabinet at many (almost half) outdoor units station are to have no alternative but method using opening cabinet door to a certain extent for a long time Come what is radiated.Have plenty of and open greatly, some specially opens to control one 10 centimetres or so of gap.Although some may be it is stolen, Even if be small base station of the device in firm anti-theft net, also have and specially cabinet door opening radiates.These ways The pollutants such as dust will obviously be entered, and be unfavorable for equipment normal work.

Proposed by the present invention " small base station Cabinet ' the outer self-loopa ' cooling energy-saving device of buoyance chamber ", it is that one kind exists When outside cabinet temperature is lower than top hot air temperature in cabinet, using in the inverted U-shaped close of vertical thirty years of age to be connected with cabinet The siphonage formed in stopped pipe road enables the air in cabinet automatically to carry out cabinet outer circulation flowing in pipeline, and Cooler air carries out heat exchange outside duct wall and cabinet in flow process, so that the air in cabinet be enable to cool down automatically Device.Cooled down using this lasting natural ventilation equipment for not needing energy supply for cabinet, so that it may greatly reduce air-conditioning The opening time of machine does not need to open ventilation fan ventilation substantially yet, does not need more to open cabinet door, can reach energy-saving cool-down Purpose, and dust will not be entered, it not will cause the pollution in cabinet.

(3) summary of the invention: the present invention " small base station Cabinet ' the outer self-loopa ' cooling energy-saving device of buoyance chamber ", It is a kind of cooling energy-saving device that suitable Miniature communication base station outdoor cabinet uses.This device is mounted on the outdoor of small base station On cabinet [6], it is made of one or several (one group) inverted U-shaped sealing pipeline systems.Inverted U-shaped pipe-line system is by air inlet [1] With uplink tracheae [2], top transverse pipe [3], downlink tracheae [4] and gas outlet [5] composition.The air inlet [1] of pipeline is opened in machine Cabinet top and the gas outlet of cabinet, and the gas outlet [5] of pipeline is opened in the lower part of cabinet and the air inlet of cabinet.This Pipeline gas self-loopa running system is air-tightness.What is flowed inside pipeline is the derived hot-air out of cabinet, with pipe The air outside cabinet outside road closely is not communicated with each other.The main heat sink part of this air-tightness pipe ventilated radiator structure, It is vertical thirty years of age of uplink tracheae [2], top transverse pipe [3] and downlink tracheae [4], hot-air in air inlet [1] and cabinet The upper space at place is connected, and being directly open, (front of cabinet is cabinet on the top of the top surface of cabinet or side or the back side Door) and cabinet gas outlet；And the gas outlet [5] of pipe-line system is then opened in lower part and the cabinet of side of cabinet or the back side Air inlet, be connected with the lower space where air cooler in cabinet.Therefore, uplink tracheae [2] and downlink tracheae [4] be not It is isometric.Downlink tracheae [4] is more longer than uplink tracheae [2], about grows the height between cabinet air inlet [1] and gas outlet [5] It is poor to spend.Including uplink tracheae [2], top transverse pipe [3] and downlink tracheae [4], vertical thirty years of age of inverted U-shaped air-tightness pipe The height of road radiator structure, that is, height locating for top transverse pipe [3], according to the hair for the apparatus installed in cabinet Amount of heat can select between 3 meters to 20 meters, and the diameter of pipeline selects between 4 centimetres to 20 centimetres.According to specific Situation is typically chosen the height of pipeline configuration at 6 meters or so, and pipe diameter is advisable at 10 centimetres or so.

When the temperature of outside cabinet is lower than cabinet internal upper part hot air temperature, the " ' buoyance chamber of small base station Cabinet Outer self-loopa ' cooling energy-saving device " (referred to as " the outer self-loopa cooling device of Cabinet buoyance chamber "), can make air outside cabinet The principle of automatic cycle flowing operation, is inside uplink tracheae [2] and downlink tracheae [4] due to vertical thirty years of age of sealing pipeline Air themperature heat, cool difference, thus different specific gravity is respectively provided with, so that hotter lighter air inside uplink tracheae [2] Rise, and cooler heavier air sinks inside downlink tracheae [4], siphonic effect is formed in sealing pipeline, and (this and water are close Tube sealing Dao Liyin atmospheric pressure is similar with the siphonic effect that difference in height is formed, but different), automatic one-way flow is generated, thus will Hot-air in cabinet is guided out outside cabinet automatically from air inlet [1] above, flows through the sealing pipeline outside cabinet, and across appearance The duct wall to readily conduct heat carries out heat exchange with air cooler outside cabinet, flows back to again from following gas outlet [5] after cooled In cabinet, ventilation is flowed naturally with regard to forming the lasting air for not needing to energize.By air in this cabinet continue into Capable " the outer self-loopa of cabinet " flowing, cooler air carries out heat exchange outside tube wall and pipeline, so that it may be reached for cabinet The purpose of interior hot-air cooling, the automatic temperature for reducing air in cabinet approach it with temperature cooler outside cabinet.At this In, it should be noted that entire pipe-line system must be air-tightness, otherwise just be difficult to form effective siphonic effect and air One-way circulation flowing.

The seal connecting method of pipeline can weld, can also with added with seal washer screw-socket docking or ring flange The modes such as docking connect.The place that the air inlet and air outlet of pipeline are connected with cabinet, preferably with ring flange docking mode Flexibly connection, in order to mount and dismount.When air inlet and air outlet are mounted on side of cabinet or the back side, opening need using Ring flange connection with 90 degree of turning elbows, and need skeleton at this and increase intensity.

Due to Cabinet occupied area very little, and " Cabinet buoyance chamber outer self-loopa cooling device " have it is higher Vertical thirty years of age of pipeline, therefore in order to securely install and normal use, it is desirable to can depend on and support , the bracket that can securely erect.Under normal conditions, the outer self-loopa hot channel structure of vertical thirty years of age of buoyance chamber, Ke Yili The fixed frame [8] above cabinet is reached with the steel tower [7] beside cabinet to be supported and be fixedly mounted, it can also be by cabinet It plants dress support rod and support is fixed.

The pipeline of the inverted U-shaped air-tightness radiator structure of " the outer self-loopa cooling device of Cabinet buoyance chamber ", is by being easy Made of the metal material of heat transfer.Due to being outdoor application, material itself will have weatherability, or carry out the table of weatherability Surface treatment.Moreover, in order to reinforce area, efficiency and the speed of the inside and outside air heat exchange of pipeline, it is preferred to use had outside pipeline scattered The finned tube of backing makes, especially more preferable using stainless steel or aluminum alloy finned tube.

Due to " Cabinet buoyance chamber outer self-loopa cooling device " be in outdoor application, just unavoidably can be by the sun It shines.And sun solarization is unfavorable for radiating, it is therefore desirable to which, in the sunny slope that can be shone by the sun, installing additional can the sunshading board that shines of the anti-sun [9].Sunshading board slightly leaves some distances with hot channel, without being in contact with hot channel, avoids the sun shining generation Heat passes on heat-dissipating pipe.In order to can sunshade again do not keep out the wind, to be conducive to radiate, sunshading board can be separated into three, mutually Mutually independently, there is the gap appropriate that can be divulged information between.Sunshading board can be mounted on pipe by the fixed plate [10] not readily conducted heat On road.

Once the outer temperature temperature of cabinet exceeds the temperature of top hot-air in cabinet, by the warmed-up pipeline of gas outside cabinet In gas, it is hotter than in cabinet in the pipeline outside cabinet since its specific gravity is smaller than the specific gravity of top hot-air in cabinet The hotter air of air, will not automatically flow into cabinet, will not influence air conditioner and cool down to cabinet.It when necessary, can also be with Install a slim and graceful check valve sheet additional at the air inlet [1] of pipe-line system, when temperature exceeds top temperature in cabinet outside cabinet, meeting Air inlet is automatically closed, cuts off the flowing of air, and outside cabinet temperature than in cabinet top temperature it is low when, valve plate can automatically turn on, Flow air.The open and close of valve plate can be controlled using simple mechanical system, can also be controlled using temperature control circuit.

Energy conservation is realized using " the outer self-loopa cooling device of Cabinet buoyance chamber " in small outdoor all-in-one machine base station, not only The cost disposably put into is extremely low, and safe and reliable, does not need to carry out maintenance and subsequent investment, also absolutely not noise and dirt Dye, although cannot replace the effect of air conditioner completely in day heat, can significantly reduce the working time of air conditioner, save Air conditioner electricity consumption extends the service life of air conditioner.Meanwhile this low-cost basic facilities will not also be as air conditioner and storage Battery becomes the target of robber's pilferage like that, will not lose effectiveness because stolen.As long as the outer temperature of cabinet is not higher than warm in cabinet The temperature of air, this device can constantly automatic running play energy-saving cool-down effect.In addition, this device is mounted in On cabinet, also on cabinet, there is no occupancy horizontal area and spaces, therefore will not influence in transverse direction in occupied space Roadside installation that region is restricted, narrow.

This energy saver is suitble to use in China, even the area that southern temperature is relatively high, also has more Half time was in period of the outer temperature of cabinet lower than hot air temperature in cabinet, and this cooling device can play energy saving work automatically With.

(4) Detailed description of the invention: Fig. 1 is mounted in tool, and there are three " the small-sized bases on the integrated base station Cabinet of unit cabin Stand Cabinet ' the outer self-loopa ' cooling energy-saving device of buoyance chamber ", the longitudinal schematic diagram watched from rear of cabinet.Herein, It describes the problem for simplicity, has only drawn a unit, and in fact, two can be installed according to the needs that cabinet cabin is radiated Even three " the outer self-loopa cooling device of Cabinet buoyance chamber " units.If the pipe that vertical thirty years of age of two or three units It can be supported mutually in appropriate height with the skeleton not readily conducted heat, and be fixed on the fixed frame [8] of steel tower stretching by road On, or install on a light special support rod at the closely cabinet, it is fixed with fixed frame [8].

Illustrate the air of cabinet this to number mark [5] from number mark [1] by number mark [2], number mark [3], number mark [4] The path of cabinet outer circulation flowing is carried out in cooling energy-saving sealing pipeline device.

Wherein, number mark [1] indicates the air inlet of this plumbing installation, while being also the outlet for being opened in cabinet top (top) Mouthful；Number mark [2] indicates uplink tracheae；Number mark [3] indicates top transverse pipe；Number mark [4] indicates that downlink tracheae, number mark [5] indicate The gas outlet of pipe-line system, while being also the air inlet for being opened in cabinet lower part (back side)；Number mark [6] indicates the machine of three units Cabinet；Number mark [7] indicates steel tower or support rod；What number mark [8] indicated to stretch out from steel tower or support rod being capable of load-bearing and in certain journey The fixed frame of supporting pipeline device on degree, number mark [9] indicate that sunshading board, number mark [10] indicate for sunshading board to be installed on pipeline Fixed plate.

(5) specific embodiment: in general, " ' outer self-loopa ' the cooling energy-saving dress of buoyance chamber of small base station Cabinet Set " uplink tracheae [2], top transverse pipe [3], downlink tracheae [4] is by being easy to conduct heat and lighter with weatherability Metal fin pipe (such as aluminum alloy finned tube or stainless steel finned tube) is sealed composition.It is significant to note that this Covering device arrives uplink tracheae [2], top transverse pipe [3], downlink tracheae [4] since air inlet [1]], until gas outlet [5], It all is at air-tightness connection status.That is, air, both will not be from certain during whole cabinet outer circulation in cabinet It is flowed out at a gap, there will not be the outer air of cabinet and flowed into from some gap.Entire pipe-line system only realizes sealing, ability With effective siphon effect and play automatic cycle cooling effect.

Although the circulating ventilation system of this device is not linked up directly with air outside cabinet, plumbing installation can be passed through Wall, especially outside the tube wall and fin, with cabinet of the metal fin pipe with large access area and high capacity of heat transfer air into Row heat exchange.Moreover, as long as the outer temperature of cabinet is lower than the temperature of top hot-air in cabinet, into the hot-air and machine in pipeline Outside cabinet cooler air carry out heat exchange and after radiating, will be automatically along downlink tracheae [4] to sinking, and through gas outlet [5] It is flowed into cabinet, and simultaneously, the hot-air of top also can flow into the pipeline radiating device from air inlet [1] automatically in cabinet In pipeline, and sequence passes through the uplink tracheae [2] being tightly connected, top transverse pipe [3], into downlink tracheae [4], and by going out Port [5], is flowed back in cabinet, one-way circulation flowing is formed, without reverse flow occurs.During this is circulated, Hot-air carries out hot friendship simply by air cooler outside the wall and fin and cabinet of pipeline in the cabinet of flow ipe system It changes.Due to during entire heat exchange, air be the outer air of cabinet is not directed by pipe sealing, therefore The pollutants such as dust in cabinet would not be brought into.Again due to this circulate be using the natural law, by because hot-air with The specific gravity of cool air it is different and caused by ascending, descending effect and siphon effect be formed by gravity-flow ventilation, Lai Shixian circulate and Heat exchange is carried out, therefore is not consumed energy, also without noise and pollution.And be warm in summer, when temperature compares machine outside cabinet When the hot air temperature of top is higher in cabinet, even if the hot-air outside cabinet heated the air in cabinet Outer Tube, due to this The air specific weight hotter than top hot-air in cabinet is lighter in kind pipeline, would not flow into cabinet, will not lead in pipeline It causes temperature in cabinet further to increase, the cooling carried out under such state using air conditioner will not be influenced.

Since this pipeline configuration is relatively high, when being directly installed on cabinet, installation position can not only be generated biggish Pressure, but also can be generated in wind it is biggish rock stress, therefore not only the corresponding site of cabinet needs steel skeleton Reinforce, and need to stretch out the fixed frame that can have support and load-bearing effect using the steel tower on side, to this pipe-line system It is fixed and supports, to reduce pipeline to the pressure of cabinet and to rock stress.Preferably with relatively thin lighter and weather-proof Property good stainless steel or aluminum alloy finned tube make pipe-line system.

It also needs that sun visor is installed in the sunny slope of pipeline, otherwise can reduce the cooling effect of gas in pipeline because the sun shines Fruit.
