Description
Technical field
The present invention relates to a kind of radiating cabinet, especially micro-power consumption radiating cabinet of using of electronic information machine room.
Background technology
Along with socioeconomic development, the level of informatization improves constantly, particularly along with the development of the technology such as cloud computing, the Internet, ecommerce, Internet of Things, be that common carrier or government, enterprise all need to build a large amount of electronic information machine rooms and comprise that data center is as base support.Electronic information machine room is be used to the place of electronic message unit and corollary equipment thereof is installed, and as data equipment etc., its caloric value is very large.Along with the technical development of electronic message unit in recent years, Single Cabinet power continues to increase.
Just depositing and installing for electronic message unit of the rack that traditional electronic message unit is used.For guaranteeing the normal operation of electronic information machine room equipment, machine room needs the throughout the year uninterrupted refrigerating operaton of air-conditioning system to dispel the heat to rack.At present, conditional electronic information machine room refrigeration radiating mode is by fan action, the hot-air of machine room to be back to air-conditioning unit inside by the special air conditioning for device room that is arranged in the machine room one or both sides, the evaporator of machine room hot-air and air-conditioning inside (air-cooled) or surface cooler (water-cooled) carry out heat exchange, the heat of hot-air is taken away by the freon in evaporator or the chilled water in surface cooler, becomes immediately the cold air machine room of blowing again equipment is dispelled the heat.This machine room refrigeration modes, air are after focusing on, to send into the distribution that machine room carries out air quantity again, thereby realize the rack refrigeration of dispelling the heat.
There are some problems in this traditional machine room refrigeration modes, is mainly manifested in: (1) because the power of each rack of machine room is incomplete same, and therefore traditional this air is sent into the mode that machine room distributes again and is difficult to rack is distributed according to need after focusing on.No matter simultaneously, due to the increasing of Single Cabinet power, adopt traditional special air conditioning for device room air supply mode, be upper air-supply or lower air-supply, all is prone to machine room local overheating phenomenon.(2) because Single Cabinet power is excessive, certainly will need to configure more special air conditioning for device room, particularly more at some high-grade high guarantee machine room redundancy backup air-conditionings, no matter adopt single-sided arrangement or bilateral arrangement, all be difficult to install the air-conditioning of requirement.(3) when outdoor temperature, during lower than the machine room indoor temperature, still enable the mode of compressor work refrigeration, the waste mass energy.
Because there are these problems in traditional special air conditioning for device room system, 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, and a kind of micro-power consumption radiating cabinet is provided.
In order to solve the problems of the technologies described above, the invention discloses a kind of micro-power consumption radiating cabinet, comprise rack body, rack main entrance and rack tailgate be used to placing electronic equipment, described rack main entrance is provided with cellular ventilation hole, and described rack tailgate is provided with fan.
In the present invention, described rack body is provided with more than one micro-channel heat exchanger near rack tailgate one side, and each micro-channel heat exchanger is provided with the refrigerant pipe interface that connects external water freon heat exchanger.
In the present invention, in each micro-channel heat exchanger, be provided with ventilation hole or ventilation gap.
In the present invention, the micro-channel heat exchanger below is provided with water-collecting tray.Water-collecting tray can receive condensed water and in time drain into condensing water conduit.
In the present invention, fan can be accessed by the UPS uninterrupted power supply.
The present invention has changed the refrigeration modes of conditional electronic information machine room, and the installing space of depositing of refrigeration radiating unit and electronic message unit is combined well.
Rack body of the present invention is for depositing the installation electronic message unit, during the electronic message unit operation, distribute a large amount of heats, the building environment cold air enters rack by the rack main entrance equipment is carried out to cooling under the swabbing action of fan, cooling rear temperature rises and becomes hot-air, and hot-air drains into machine room through after being cooled again of the tailgate micro-channel heat exchanger of rack.
Micro-power consumption radiating cabinet of the present invention is that the set electron information equipment is deposited installation, equipment cooling freezes in one, with external system, has simultaneously the technical products of heat exchange interface.
Rack body interior of the present invention pressure, temperature sensor can be set, and outside freon transducer.
Beneficial effect: micro-power consumption radiating cabinet shown in the present, solved the problem that conventional machine room planning and air-conditioning system exist, micro-channel heat exchanger is arranged in rack, rather than being arranged in the one or both sides of machine room, its beneficial effect shows the following aspects: the problem that 1) has solved the uneven or local overheating that causes because of cabinet equipment power difference of conventional air-conditioning scheme air-supply; 2) because refrigeration unit can promote the equipment installation power of Single Cabinet greatly at interior of equipment cabinet, solve the refrigeration radiating problem of high power rack, this is a technical bottleneck for the conventional air-conditioning system; 3) other one or both sides due to machine room no longer need to arrange air-conditioning equipment, can discharge this piece air conditioning area area be used to electronic message unit is installed, and have improved the machine room utilance; 4) in the lower period of outdoor temperature, can utilize outdoor cold source to carry out system cooling, because the rack temperature of outgoing air is high, improved the service time that heat transfer temperature difference can extend outdoor cold source, greatly save air conditioning energy consumption.
