Variable air rate air-flow persuader 3 self adopts the single-chip microcomputer intelligent control technology, automatic collecting temperature information, and regulate rotation speed of the fan voluntarily.When temperature was high, variable air rate air-flow persuader rotation speed of the fan was fast, and when temperature was low, variable air rate air-flow persuader rotation speed of the fan was slow, thereby carries out the cold supply by the actual demand of cooling machine cabinet.
As one embodiment of the present of invention, variable air rate air-flow persuader is the rotating speed of totally 8 shelves, and air output is 300cmh (cubic metre/hour), and the ratio of temperature and rotation speed of the fan is the temperature traffic coverage distribution automatically in 30%~90% power condition with actual set.
The structure of variable air rate air-flow persuader can comprise that casing, casing are provided with switch, at least one air inlet, at least one air outlet, between air inlet and air outlet, are provided with at least one air channel, are used to control the controller and the fan of fan wind speed and air quantity.As shown in Figure 5, shown the air inlet of variable air rate air-flow persuader and the position and the direction of air outlet.It will be understood by those skilled in the art that illustration is exemplary, the variable air rate air-flow persuader that carries out modify and distortion in view of the above can be applied to the present invention.
As one embodiment of the present of invention, can also adopt the computer centralized control, the device of communication equipment temperature also comprises intelligent management system in the promptly said adjusting machine room, structural representation is as shown in Figure 6.The temperature signal of said temperature sensor collection communication equipment becomes temperature signal into voltage signal, is transferred to intelligent management system.Intelligent management system calculates the actual heat dissipation capacity of communication equipment in the rack, the rotation speed of the fan of control variable air rate air-flow persuader.Induce the wind speed and the air quantity of the cold wind entering rack in the cold passage, control passage of heat return air approach.In this mode, intelligent management system plays central controlled effect, to each variable air rate air-flow persuader sending controling instruction.
Intelligent management system network enabled IP address and direct cable connect; Also be connected with watch-dog and data recording equipment; Said watch-dog is used for the temperature of monitoring communications equipment, the wind speed and the air quantity of variable air rate air-flow persuader, and said data recording equipment is used to write down the wind speed and the air quantity of temperature, variable air rate air-flow persuader.As one embodiment of the present of invention; Intelligent management system is connected with variable air rate air-flow persuader through the RS485 bus, on intelligent management system, also is connected with the remote monitoring computer, is connected with the printer that can record data be exported, the memory device that is connected with the scheduled store management data through computer network interface.Certainly, can also connect other and be used to the equipment monitoring and be used for recording data information.
The present invention is installed in the cabinet door inboard with temperature sensor, and the temperature of obtaining communication equipment makes the air quantity of variable air rate air-flow persuader according to the adjustment entering rack of communication equipment more accurately, reaches the purpose of similar accurate air-supply.Blow by ambient temperature fully with machine room in the prior art and the mode of cooling device is compared, can reach the effect of better reduction communication equipment temperature, and improve the capacity usage ratio of air-conditioning system.
The present invention is installed in the cabinet door outside with variable air rate air-flow persuader, installs back-to-back with temperature sensor, can reach the effect of cold and hot passage.Cold and hot passage can reduce the mixing of hot and cold air, and the hot gas that also can reduce front-seat rack discharge has influence on back row's equipment.By the cold and hot channel flow that designs, optimize " the cold and hot passage " of machine room and accurately sending in machine room, return air air quantity and give, the return air wind speed.Mode by at interval is provided with cold and hot passage, and air-conditioning cold wind is delivered to cold passage, make that cold wind is sent into rack after, be discharged to the passage of heat to return the air-conditioning return air inlet through the guiding of variable air rate air-flow persuader.Thereby make hot and cold air separate.
As one embodiment of the present of invention, the cold passage between air-conditioning and variable air rate air-flow persuader is provided with ajutage, and the passage of heat between air-conditioning and variable air rate air-flow persuader is provided with backwind tube, can reach better cooling effect.
The present invention can also reduce the short circuit of air-conditioning air-flow.The air-flow short circuit mainly is that air-conditioning is seen next cold wind off; Also do not inhaled through return air by air-conditioning again and go back through cold and hot exchange; Main cause is that air current composition is unreasonable; In the ordinary course of things, air-conditioning is seen the very difficult access arrangement inside of the cold air that comes off equipment is cooled off, and just through ambient temperature equipment is carried out natural cooling.Variable air rate air-flow persuader of the present invention can guide cold air entering communication equipment inside to carry out cold and hot exchange, reduces the air-flow short circuit.Owing to formed cold and hot passage; The cold air of air-conditioning is delivered to variable air rate air-flow persuader through cold passage; Variable air rate air-flow persuader fan rotates drive cold air and blows to communication equipment from air inlet, and hot gas is discharged through variable air rate air-flow persuader air outlet, sends into the passage of heat.Like this, the cold wind hot blast passes through different passages respectively, and ajutage and backwind tube especially are set, and has further reduced the air-flow short circuit.
Through installing the air quantity persuader additional, improved the efficient of air-conditioning, reduce the inner cold and hot imbalance of calculator room equipment, through the reducing energy consumption of VAV airflow management system, but the about saves energy 10% of each air conditioner in machine room power consumption estimation.Can solve the uneven waste of energy that causes because of the communication equipment local overheating with minimizing of heat distribution of machine room.
The present invention be directed to the communication and the air conditioner energy saving solution of information technoloy equipment machine room, mainly is that rack to small-sized communications equipment room installs variable air rate air-flow persuader additional and regulates the cold of entering rack and improve the efficient of heat exchange.For improving computer-room air conditioning system cryogenic energy utilization rate and eliminating machine room local overheating problem, has clear and definite technical characterstic.
The present invention is applicable to equipment machine rooms such as data center, computer room, switching room, transmission room and communication base station, and can adaptive multi-form air-conditioning system give, air return method; Its simple installation, it is few to implement risk, above-mentioned most of machine rooms is possessed the feasibility of enforcement.
As conclusion, should notice that those skilled in the art will be apparent to make many variations and modification to preferred embodiment, and not break away from principle of the present invention in fact describing in detail.This variation and modification are included within the described scope of the present invention of appended claims.
