Description

Distributed cooling system for mobile communication base station equipment
Technical field
The utility model relates to cooling system, relates in particular to a kind of distributed cooling system of mobile communication base station equipment.
Background technology
" energy-saving and emission-reduction " are the fundamental state policies of China.Along with the fast development of communication need and Internet technology, communication operator continues to increase the construction dynamics of mobile communication base station.In order to guarantee the operation reliably and with long-term of heating electronic equipment in the base station, must dispose corresponding cooling, the base station air conditioner system that promptly is commonly called as.According to the AUTHORITATIVE DATA statistics, the mobile communication base station air conditioning energy consumption accounts for more than 50% of whole base station energy consumption.Therefore, the energy-conservation energy-saving and cost-reducing emphasis of operator that becomes of base station air conditioner has remarkable economical and social benefit.
Different with the design parameter and the use occasion of civilian comfort air conditioning system, the mobile communication base station air-conditioning belongs to technological air conditioning.The core of its cooling is efficiently, the heating of communication base station electronic equipment is discharged in the outdoor environment reliably.The base station electronic equipment all has strict requirement to environment temperature, humidity and cleanliness factor.Existing communication base station special air conditioner technology is still immature, often directly selects civilian comfort air conditioning system for use, or transforms a little whole base station machine room space is cooled off.This air conditioning mode not only can't be given full play to the design advantage of comfort air conditioning system, a large amount of colds are used to offset the thermic load in base station machine room space, and only have the form of small part by heat convection to be used for cooling heat-generating devices itself, therefore cause the significant wastage of electric energy.In existing communication base station air conditioner technology, deliver to the air-conditioning form of each electronic equipment after also being included as the special air conditioner unit of base station design and focusing on wind again.In these two kinds of units, the former air conditioning area is whole base station machine room, rather than directly towards cooling object (heat-producing device), certainly will cause the energy waste of air-conditioning enlarged areas like this; Latter air channel had both taken the machine room space, was difficult to the environment cleanliness of control appliance again, and the heat exchange efficiency between return air and evaporimeter is not high in addition, made energy-saving effect not remarkable.
Investigation is found through domestic and international patent: at present both at home and abroad in the base station air conditioner patent, developed countries such as Japan have the patent of more better quality on to the air conditioning mode of communication apparatus and control mode thereof; Domestic patent mainly concentrates in the special-purpose unit improvement of technological air conditioning base station air conditioner.For example, in a kind of patent of invention that replaces compressor with pump, have certain energy-saving effect, but practicality and little; A kind of scheme of introducing new air cooling equipment in the winter time can reduce the air-conditioning refrigeration duty to a certain extent, but has increased extra blower fan and pipeline equipment, and can not guarantee higher environment cleanliness.Therefore, the OO type of cooling can't be really realized, under the prerequisite that guarantees the environment air-conditioner precision, truly energy-conservation can not be reached.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes existing mobile base station air-conditioning scheme, and a kind of distributed cooling system of communication base station equipment is provided.
The distributed cooling system of communication base station equipment comprises compressor, condenser, restricting element, condenser fan, one or more base stations heat-producing device cooling device, compressor is connected with condenser, restricting element, base station heat-producing device cooling device successively, and base station heat-producing device cooling device comprises evaporimeter, evaporator fan, flow control valve.
The air outlet of the evaporimeter in the heat-producing device cooling device of described base station directly contacts with the air inlet of base station heat-producing device.A plurality of base stations heat-producing device cooling device adopts the tandem of pure tandem, band bypass pipe, parallel or series parallel type connection.The exit of evaporimeter and compressor is provided with the thermometric load cell.Base station heat-producing device cooling device adopts full air return system, and full air return system is that the air inlet by evaporimeter is connected by pipeline with the air outlet of heat-producing device.
The utility model compared with prior art has obvious energy-saving effect.Distributed cooling system directly cools off heat-producing device, and promptly direct object-oriented need not other spaces of equipment room are cooled off, and has reduced the air-conditioning area, reduces refrigeration duty; Owing to directly equipment is cooled off, the evaporating temperature of evaporimeter is able to suitable raising, thereby has improved coefficient of refrigerating performance (COP) value of kind of refrigeration cycle; Adopt multiple connected mode flexibly, be applicable to the setting of different types of communication base station cooling system; To the full return air form that the different heat-producing device of caloric value carries out distributed cooling and can adopt the base station cooling device, can improve the environment control accuracy of heat-producing device, thereby prolong the service life of equipment.
