Description

Finned tube heat dissipation cooling energy-saving device for unattended machine room or base station

The technical field is as follows: the invention belongs to the technical field of communication machine room and base station energy conservation.

(II) background technology: various unattended machine rooms and mobile communication base stations with all-year-round automatic operation of electrical equipment are usually in a closed state due to unattended operation. The communication equipment inside can generate heat continuously when running even if being novel energy-saving equipment, and if the heat cannot be dissipated in time, the indoor temperature can be increased continuously, so that the equipment is difficult to continue to run normally. In order to maintain the normal operating temperature of the equipment, it is necessary to dissipate heat generated during the operation of the equipment to the outside. For this purpose, temperature control (temperature reduction) is generally performed by an air conditioner. The accumulated consumed electric quantity of each machine room and each mobile communication base station for the temperature-controlled air conditioner for maintaining the normal working temperature is not small. More than ten years ago, a fresh air energy-saving system for cooling equipment by introducing outdoor cold air is developed when outdoor temperature is low. Although the fresh air energy-saving system can save energy, outdoor cold air must be introduced to cool equipment, the ventilation volume of a common fresh air system is large, outdoor dust and other pollutants are easily brought into a room, even if an air filtering device is adopted at an air inlet, frequent maintenance is required, and indoor pollution is still difficult to avoid. The ventilation system still consumes a lot of electric energy, and is equipped with a relatively complex automatic control system, and the use and maintenance costs are relatively high.

The applicant proposes an inverted U-shaped single-pipe siphon cooling energy-saving device for an unattended machine room or a base station, which is a technical scheme that hot air in the machine room or the base station is pumped out of a room by using a chimney effect of the hot air in an ascending air pipe, and indoor hot air can automatically flow in a closed circulation mode outside the room by using a siphon effect formed in a closed inverted U-shaped single-pipe system to exchange heat with outdoor cold air through a pipe wall, so that cooling and energy saving are realized. The technical scheme overcomes the defects of a fresh air energy-saving technology, but has the defect of too high device and is not easy to install. The finned tube heat dissipation, cooling and energy saving device used in the unattended machine room or the base station not only retains the advantage that the former case enables indoor air to automatically circulate and flow in an outdoor closed pipeline so as to realize cooling and energy saving, but also overcomes the defect that the pipeline of the former case device is too high.

(III) the invention content: the invention relates to a finned tube heat dissipation and cooling energy-saving device used in an unattended machine room or a base station, which is a closed pipeline system formed by sequentially and hermetically connecting one set or a plurality of sets of finned tubes, wherein the finned tube heat dissipation and cooling energy-saving device is arranged on the top surface or outside the side wall of a machine room or a base station [8], and comprises an air inlet [1] formed in the top surface or the side wall of the upper space of the machine room or the base station [8], an upper air pipe [2] hermetically connected with the air inlet and vertically higher than the top surface of the machine room or the base station [8], a top horizontal pipe [3], a lower air pipe [4], a finned tube radiator [5], a further downward air return pipe [6] and an air outlet [ 7; or a top horizontal pipe [3] and a down air pipe [4] are omitted, an air inlet [1] is directly connected with an inlet above a finned tube radiator [5] horizontally or vertically arranged on the top of a machine room or a base station [8] through an up air pipe [2] which is vertically higher than the top surface of the machine room or the base station [8], air after heat dissipation through the finned tube radiator [5] is hermetically connected with an air inlet in the lower space of the machine room or the base station [8] from an outlet below the finned tube radiator [5] through a down air return pipe [6] and an air outlet [7] of a pipeline system, and the whole system is generally in a vertical lifting-descending-before-falling inverted-U-shaped pipeline structure with a part higher than the top surface of the machine room or the base station [8 ].

When the outdoor temperature is lower than the temperature of the hot air in the upper space of the room, the hot air gathered in the upper space of the room or the base station can be automatically pumped into the upper air pipe [2] connected with the air inlet from the air inlet [1] due to the chimney effect because of light specific gravity, further flows into the top horizontal pipe [3] and the lower air pipe [4], then flows into the upper air inlet of the finned tube radiator [5] horizontally or longitudinally arranged on the top surface of the room or the base station or outside the side wall, and flows into the lower air return pipe [6] from the lower air outlet of the finned tube radiator [5] after the full heat dissipation of the upper air pipe [2], the top horizontal pipe [3], the lower air pipe [4] and the finned tube radiator [5], and finally flows back to the lower space of the room or the base station [8] from the air outlet [7] communicated with the lower space of the room or the base station [.

When the outdoor temperature is lower than the temperature of hot air above the room, in the sealed pipeline, due to the different specific gravity of hot air and cold air, the chimney effect generated in the upward air pipe [2] promotes the flow of air, and the siphon effect formed by heat rising and cold falling in the integrally vertical pipeline system with the inverted U-shaped structure promotes the natural flow of air in the pipeline system, so that the hot air in the room or the base station [8] can continuously enter the sealed pipeline positioned outdoors, and exchanges heat with the cold air outside through the pipeline wall (and the fins on the pipeline) which is easy to transfer heat, and returns to the room after the outdoor temperature is reduced and subsided. The purpose of cooling the indoor hot air can be achieved through the continuous circular flow of the indoor air in the outdoor sealed pipeline and the heat exchange between the indoor air and the outdoor cold air through the pipeline wall which is easy to transfer heat. The continuous natural ventilation cooling device does not need energy supply, so that the starting time of the air conditioner can be greatly reduced, and the aim of saving energy is fulfilled. Especially when outdoor temperature is lower in autumn, winter and spring, the energy-saving effect is more obvious.

Because the whole pipeline system is located outdoors, the pipeline system is made of weather-resistant and easily heat-conductive metal materials, and a sun-proof and sun-shading board (10) which does not influence ventilation is additionally arranged on the pipeline system.

Because the finned tube radiator [5] is used as a device for bearing the main radiating task, the height of the vertical inverted U-shaped pipeline structure consisting of the upper air pipe [2], the top horizontal pipe [3] and the lower air pipe [4] can be obviously reduced, and the finned tube radiator has certain radiating function and mainly plays the roles of air extraction and air introduction into the finned tube radiator [5 ]. The height of the ascending air pipe [2], the top horizontal pipe [3] and the descending air pipe [4] is about 2 meters higher than the top surface of the machine room or the base station [8 ]. The diameters of the ascending air pipe [2], the top horizontal pipe [3], the descending air pipe [4] and the descending air return pipe [6] are generally between 10 cm and 20 cm. One set, two sets or more sleeve pipeline systems can be adopted according to the heat dissipation capacity required. A bracket [13] capable of supporting and fixing a pipeline system can be arranged on a machine room or a base station [8], and a sun shield [10] is arranged on the bracket [13 ]. The top horizontal pipe [3] and the lower air pipe [4] can be omitted, the upper air pipe [2] is directly connected with an air inlet above a finned tube radiator [5] arranged on the top of a machine room or a base station [8], so that the height can be further reduced, but because the air pumping force is insufficient, the air flowing speed in the closed pipeline is slow, and the heat dissipation effect is poor. In this case, a small fan [9] may be installed near the air inlet [1] of the duct system to accelerate the flow rate of the air in the duct by turning on the small fan. The installation of the small fan needs to be noticed, and the small fan can not only blow air into the pipeline when being started, but also can not block natural air inlet when not being started. The small fan can be self-sufficient without external power supply by relying on solar cells [11] mounted on the sun visor [10 ]. The small fan is automatically controlled by the temperature control device to be started only when the temperature difference between the indoor and the outdoor is small and the outdoor temperature is still lower than the temperature of the hot air above the indoor, and the small fan is automatically closed once the outdoor temperature is higher than the temperature of the hot air above the indoor so as to prevent the air in the pipeline heated by the outdoor hot air from entering the indoor in a circulating manner.

When the outdoor temperature is lower than the temperature of hot air above the room, the finned tube heat dissipation and cooling energy-saving device used in an unattended machine room or a base station can be used for automatically realizing the circulation flow of the indoor air outdoors, and the hot air in the machine room or the base station is cooled and cooled in the circulation flow process. The sealing connection method of the pipeline is various, and the pipeline can be welded, or can be connected by screw port butt joint, buckle or flange plate butt joint with a sealing washer.

The finned tube radiator [5] arranged on the top surface of the machine room or the base station [8] can be horizontally arranged or vertically arranged. The horizontally arranged finned tube radiator [5] has a multilayer composite structure, each layer is formed by connecting two or three or more parallel finned tubes in parallel, and is divided into two layers, three layers or more from an air inlet at the upper part, the layers are connected in series or in parallel, and the layers descend layer by layer, so that the air inside can be cooled from heat through heat exchange with the cool air outside the pipeline through the pipeline wall in the process of flowing from top to bottom until the air flows out from an outlet at the bottom layer of the finned tube radiator [5], flows through a descending air return pipe [6] and an air outlet [7] of a pipeline system and enters the lower space of a machine room or a base station [8 ]. The vertically installed finned tube radiator [5] is formed by mutually connecting a plurality of rows and a plurality of columns of vertical finned tubes in parallel, air is fed from an air inlet at the upper part, and flows into a descending air return pipe [6] and an air outlet [7] of a pipeline system from an air outlet at the lower part after heat dissipation is carried out by the plurality of rows and the plurality of columns of vertical finned tubes which are connected in parallel, and then enters the lower space of a machine room or a base station [8 ]. When the outdoor temperature is higher than the indoor hot air temperature in summer, the air in the pipeline system has higher temperature than the indoor hot air, and the specific gravity is lighter, so that the air floats on the air and cannot flow into the indoor space. At the moment, the air conditioner is started to cool the room, and the influence of a pipeline system is avoided. In order to ensure that the air in the whole pipeline system flows in a unidirectional way, the descending air return pipe [6] can be inserted into a room from the upper part of a machine room or a base station [8] so as to avoid the problem that the hot air flows back upwards in the descending air return pipe [6] below the top surface of the machine room or the base station [8] when the outdoor temperature is too high in summer. If the down air return pipe (6) is outdoor, the air outlet (7) is arranged at the air inlet at the lower part of the machine room or the base station (8), in order to avoid the backflow problem, a one-way valve (12) can be additionally arranged at the air inlet at the lower part of the machine room or the base station (8) (namely the air outlet (7) of the pipeline system) to prevent backflow. Because the wind pressure of the air in the pipeline which continuously and circularly flows is not large, the additionally arranged check valve [12] should use a light material and a structure with high sensitivity, and the check valve [12] is in a completely opened state at ordinary times through artificial control, and only in hot summer, the check valve [12] is in a working state of controlling the unidirectional flow of the air flow.

The finned tube radiator [5] arranged outside the side wall (especially the shady side) of the machine room or the base station [8] can also be arranged horizontally or vertically. The horizontally arranged finned tube radiator [5] has a multilayer composite structure, each layer is formed by connecting two or three or more parallel finned tubes in parallel, and is divided into two layers, three layers or more from an air inlet at the upper part, the layers are connected in series or in parallel, and the layers descend layer by layer, so that the air inside can be cooled from heat through heat exchange with the cool air outside the pipeline through the pipeline wall in the process of flowing from top to bottom until the air flows out from an outlet at the bottom layer of the finned tube radiator [5], flows through a descending air return pipe [6] and an air outlet [7] of a pipeline system and enters the lower space of a machine room or a base station [8 ]. The vertically installed finned tube radiator [5] is formed by mutually connecting a plurality of rows and a plurality of columns of vertical finned tubes in parallel, air is fed from an air inlet at the upper part, and flows into a descending air return pipe [6] and an air outlet [7] of a pipeline system from an air outlet at the lower part after heat dissipation is carried out by the plurality of rows and the plurality of columns of vertical finned tubes which are connected in parallel, and then enters the lower space of a machine room or a base station [8 ]. Different from the finned tube radiator [5] arranged on the top surface of a machine room or a base station [8], the finned tube radiator [5] arranged outside the side wall of the machine room or the base station [8] is positioned below the top surface of the machine room or the base station [8], and hot air heated by outdoor air in the finned tube radiator [5] and the air return pipe [6] positioned below the top surface of the machine room or the base station [8] is likely to reversely flow back when the outdoor temperature is overhigh in summer, so a one-way valve [12] capable of controlling the air flow direction is needed, the air in the pipeline can only enter from an air inlet [1] above the machine room or the base station [8], sequentially passes through an upper air pipe [2], a top transverse pipe [3], a lower air pipe [4], a finned tube radiator [5] and the air return pipe [6], and finally flows back to the lower space of the machine room or the base station [8] from an air outlet [7] communicated with the lower space, and cannot flow in the opposite direction. This is important when the outdoor air temperature is higher than the indoor hot air temperature in summer. Because the air in the pipeline system has higher temperature and lighter specific weight than the indoor hot air, the hot air in the finned tube radiator [5] arranged outside the lower side wall of the top surface of the machine room or the base station [8] flows into the room through the lower air pipe [4], the top horizontal pipe [3] and the upper air pipe [2] in reverse order through the upper air inlet [1] of the machine room or the base station [8 ]. When the air conditioner is started to cool the room, the air conditioner is influenced by the backflow of the pipeline system, and the burden of the air conditioner is increased. The one-way valve [12] is arranged at an indoor air inlet (namely an air outlet [7] of a pipeline system) and can be in a fixed opening state at ordinary times, and the one-way valve [12] is in a working state of controlling the unidirectional flow of air only when the temperature is high in summer.

The finned tube heat dissipation and cooling energy-saving device used in the unattended machine room or the base station is adopted in the communication machine room or the base station to realize energy conservation, has extremely low cost, safety and reliability, basically does not need maintenance, and has no noise and pollution at all. Meanwhile, the low-cost basic facility can not be the target of theft like an air conditioner and can not lose effectiveness due to theft. As long as the outdoor temperature is not higher than the temperature of the indoor hot air, the device can automatically operate to play the role of temperature reduction and energy conservation.

The energy-saving device is suitable for being used nationwide, even in regions with relatively high temperature in the south, the time interval that the outdoor temperature is lower than the temperature of indoor hot air can be in most of the time, and the cooling device can automatically play the role of cooling and energy saving.
