Description

The air-cooled energy-saving device of base station self-cleaning
Technical field
The utility model relates to energy-saving field, relates generally to the energy-saving device of communication base station, specifically is exactly a kind of novel air-cooled energy-saving device of base station self-cleaning.
Background technology
China's mobile communication cause flourish, the various types of communication base station of mobile operator construction is multiplied, and the communication base station power consumption also constantly soars, and electric cost has not been a decimal fractions.Simultaneously, the situation of national electric power energy shortage is appeared suddenly, will be very frequent in some regional power cuts to limit consumption phenomenon, and economize on electricity has become an important social topic.
At present, for guaranteeing the safe operation of base station communication apparatus, the control of the temperature and humidity in the communication base station all is to install an air-conditioner by the base station to realize, and the energy consumption of air-conditioning equipment is occupied quite great proportion in the total energy consumption of base station, because the base station carrier configuration is different, air conditioning energy consumption generally accounts for 30%~75% of base station total energy consumption.Along with closing on day by day of 3G, the equipment in the machine room will get more and more, and the power consumption of equipment and caloric value are also just increasing, and the energy consumption of air-conditioning will increase sharply.Yet, the electricity rates of facing increasingly serious electricity consumption situation and progressively raising, high electricity charge expenditure has become the cost expenditure that operator can not be ignored.
At present the communication base station room air-conditioning is set to freeze 18 ℃ mostly, or automatic 25 ℃, and some areas are annual unlatchings, and the phenomenon of waste is comparatively serious.
Because the rising of temperature mainly is because the long-time running of electric equipment is generated heat in the machine station, and as the thermoregulator air-conditioning equipment of base-station environment, finds the following problem of ubiquity in our survey:
● the temperature difference of air-conditioner temperature control is smaller, and it is frequent to cause air-conditioning equipment to start, long-time running.
● the sealing of base station machine room itself is relatively poor, and heat insulation effect is bad, makes the operation of air conditioner time extend.
● the reason that air-conditioning itself descends because of cold-producing medium reduces refrigerating efficiency, temperature control is inaccurate etc. makes operation of air conditioner time overlength.
● the part communication base station is according to designing requirement, and for guaranteeing the base station equipment security of operation, configuration one main is equipped with two air-conditionings, causes the idleness of equipment and investment waste.
Because of the air-conditioning equipment fault, the base station machine room temperature is raise fast cause disconnected station.
In other field application is arranged also about air-cooled equipment, can not be self-cleaning and the problem of good dedusting but all exist.
Because the air that ventilation blower per hour is drawn into reaches the 3000--4000 cubic meter, the dust quantity that thereupon enters is surprising, and is especially even more serious at northern area, and this constitutes very big threat to the equipment in the machine room.Therefore, the dust removal by filtration before cold air enters is extremely important.
The filtration, purification of dust is generally realized by dust pelletizing system in the air.Dust pelletizing system of a great variety is as screen pack or filter core dedusting, bag-type dusting, water dedusting, electrostatic precipitation, cyclone dust removal etc.The effect of these dust pelletizing systems is all fine, but they must use under certain environment and condition.As sponge or nonwoven fabrics screen pack dust pelletizing system, though certain dust containing capacity is arranged on the screen pack, also must regularly clean or replace new sponge or nonwoven fabrics screen pack, otherwise reduce intake greatly, have a strong impact on the inlet of cold air, thereby influence cooling-down effect.Bag-type dust removing system needs a lot of cloth bags and struts, and floor space is bigger, and must have compressed air regularly to blow and beat cloth bag, removes the dust on the cloth bag, and this structure is not only huge but also complicated.The water dust pelletizing system must have mobile water source and bigger precipitation pond.These conditions are concerning a slight base station, and especially remote, bleak and desolate area is difficult to realize.
So far, though do not see the application that self-cleaning air-cooled energy-saving device in base station is arranged on the market, do not see the relevant report of this respect yet.
The utility model project team finds report or the document closely related and the same with the utility model as yet to domestic and international patent documentation and the journal article retrieval of publishing.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned technology or device existence, provides a kind of simple in structure, reliable, dust removing effects is obvious, and the filtration, purification room air is non-maintaining for a long time, volume is little, is applicable to the air-cooled energy-saving device of base station self-cleaning in many dust area in the air.
