Description
Technical field
The present invention relates to micro-power consumption radiating cabinet that a kind of electronic information machine room is used, the electronic information machine room of especially middle low power density.
Background technology
Along with socioeconomic development, informationization technology development rapidly, particularly along with the arriving of large data age, needs a large amount of information-based machine rooms as base support.Therefore, no matter be government, common carrier, or Internet enterprises etc. all need to build a large amount of electronic information machine rooms.
Electronic message unit in machine room is being born the functions such as data storage, calculating, and for guaranteeing the normal operation of electronic message unit, machine room needs the throughout the year uninterrupted refrigerating operaton of air-conditioning system to dispel the heat to rack.At present, traditional electronic information machine room refrigeration radiating mode is by chilled water air-conditioning (water-cooled) or modular precision air conditioner (air-cooled), to concentrate heat exchange to produce to send into machine room after cold wind to carry out allocation of the amount of air and then the equipment in each rack is carried out to cooling again.
The mode of this traditional air conditioner refrigerating, exists air-conditioning draught fan energy consumption large; Air conditioner refrigeration effect is bad; Natural cooling source utilance is not high; The problems such as easy local overheating.The above problem existing for solving traditional special air conditioning for device room system, at present existing new technologies and methods scheme, particularly refrigeration unit is arranged in to micro-power consumption radiating cabinet (each rack all configures heat-sink unit) at machine room inner region rack tailgate place, the problems referred to above have been solved well, but because each rack has all configured heat-sink unit, make its investment compare and have increase with traditional air-conditioning, be relatively more suitable for high power density machine room.
Although the development along with electronic information technology, Single Cabinet plant capacity has the trend improving constantly, but most of Single Cabinet power is still in 5kW in the market, for adapting to the problem that solves traditional air conditioner in machine room on the basis of the machine room instructions for use that this part Single Cabinet power is not high, and further reduce air-conditioning investment, need a kind of new technology of research and development badly.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of micro-power consumption radiating cabinet for low power density electronic information machine room.
In order to solve the problems of the technologies described above, the invention discloses a kind of micro-power consumption radiating cabinet for low power density electronic information machine room, comprise plural for depositing the rack body of installation electronic message unit and the heat radiation refrigeration unit being connected with one of them rack body; Each rack body comprises main entrance and with the rack tailgate of louvre, the main entrance of the rack body being connected with heat radiation refrigeration unit is provided with louvre, and the main entrance of all the other rack bodies is nonventilated whole plate; Described heat radiation refrigeration unit comprises heat radiation backboard, is arranged on the axial flow blower on heat radiation backboard and is arranged on the micro-channel heat exchanger between heat radiation backboard and rack main entrance.
Heat radiation refrigeration unit of the present invention is born the heat dissipation capacity of 2～3 left and right rack body electronic message units, heat radiation refrigeration unit is positioned at rack tergal position, be the wind exhausting outlet place of electronic message unit, the namely equipment air draft of every 2～3 racks is concentrated and is entered the heat exchange of heat radiation refrigeration unit.Ventilation hole on dividing plate in rack body between main entrance, tailgate and body, is beneficial to air draft circulation.Rack quantity, power that the air quantity of fan of each heat-sink unit and quantity are born according to heat-sink unit carry out Selection and Design.The rack body of heat radiation refrigeration unit is housed and is unkitted between the rack body of heat radiation refrigeration unit as orifice plate ventilation dividing plate, after heat radiation, the hot blast of temperature after rising can enter heat radiation refrigeration unit by dividing plate.Rack body tailgate imperforate plate or the shutoff of being unkitted heat radiation refrigeration unit, hot blast can not see through, and the hot blast of avoiding being unkitted the rack body of heat radiation refrigeration unit directly enters machine room.
In the present invention, between described rack body, be provided with the dividing plate with ventilation hole, heat radiation refrigeration unit of the common use of all rack bodies.Rack body is in 3 above situations, and heat radiation refrigeration unit is preferably arranged on middle rack.
In the present invention, described heat radiation refrigeration unit is provided with freon pipe joint and condensate water discharging interface, and wherein condensate water discharging interface is positioned at the bottom of heat radiation refrigeration unit, condensed water can be drained into outside machine room.
In the present invention, the micro-channel heat exchanger inside of heat radiation refrigeration unit is filled with freon working medium.After the high temperature cold water heat exchange of gaseous fluorine Leon working medium by external system, become liquid refrigerant, at Action of Gravity Field, downstream to micro-channel heat exchanger, in micro-channel heat exchanger, be back to external system heat exchanger, thus circular flow with high temperature air exhaust heat exchange the gasification of equipment.Its corresponding pressure and evaporating temperature can meet the heat radiation refrigeration requirement of rack temperature of outgoing air.
In the present invention, described Thermal Performance of Micro Channels is more than two, and separate work.Two micro-channel heat exchangers access respectively the freon-water-to-water heat exchanger of external system two cover systems by interface, avoided Single Point of Faliure.
Micro-power consumption radiating cabinet of the present invention is that set electron information equipment is deposited installation, equipment cooling freezes in one, has the technical products of heat exchange interface with external system simultaneously.Described middle low-density electronic information machine room refer to the single chassis power of electronic message unit that rack body deposits installation about 5kW with interior machine room.
Heat radiation refrigeration unit is positioned on the main entrance of a rack body, approaches thermal source, and power of fan is little, has solved the large problem of traditional air conditioning mode fan energy consumption; Electronic message unit temperature of outgoing air is high, high temperature air draft do not enter building environment just directly enter heat radiation refrigeration unit carry out heat exchange, can improve the evaporating temperature of freon working medium in heat radiation refrigeration unit micro-channel heat exchanger, thereby improve the refrigerating efficiency of external system chilled water temperature and then raising handpiece Water Chilling Units.In addition, the natural cooling source that has also improved cooling tower cooling utilizes the time.
Because each heat radiation refrigeration unit is born the heat gain from appliance and equipment of 2～3 rack bodies, greatly reduced the investment of heat radiation refrigeration unit, compare with traditional air conditioning terminal, not only cost is lower than traditional air conditioning terminal mode, and its refrigeration, energy-saving effect are all well beyond traditional air conditioning mode.Be applicable to single chassis power 5kW with interior machine room.
