Description

Self-cleaning air-cooled power-saving equipment for base stations

technical field

The utility model relates to the field of energy saving, and mainly relates to power-saving equipment for communication base stations, specifically a new type of self-cleaning air-cooled power-saving equipment for base stations.

Background technique

With the vigorous development of my country's mobile communication industry, the number of various communication base stations built by mobile operators has doubled, and the power consumption of communication base stations has also continued to soar. The cost of electricity consumption is no longer a small figure. At the same time, the shortage of electricity and energy in the whole country has emerged, and power cuts will be very frequent in some areas, and power saving has become an important social topic.

At present, in order to ensure the safe operation of base station communication equipment, the temperature and humidity control in the communication base station is realized by installing air conditioners in the base station, and the energy consumption of air conditioner equipment occupies a considerable proportion in the total energy consumption of the base station. Depending on the frequency configuration, the energy consumption of air conditioners generally accounts for 30% to 75% of the total energy consumption of the base station. With the approach of 3G, there will be more and more equipment in the computer room, and the power consumption and heat generation of the equipment will also increase, and the energy consumption of air conditioners will increase rapidly. However, in the face of the increasingly severe electricity consumption situation and the gradual increase in electricity prices, high electricity charges have become a cost that operators cannot ignore.

At present, most of the air conditioners in the computer room of the communication base station are set to cool at 18°C, or automatically at 25°C, and in some areas, they are turned on all year round, so the phenomenon of waste is serious.

Since the temperature increase in the base station is mainly due to the long-term operation of electrical equipment, the air conditioner used as the base station’s ambient temperature adjustment found the following problems in our statistical survey:

●The temperature difference of the air-conditioning temperature control is relatively small, which causes the air-conditioning equipment to start frequently and run for a long time.

● The airtightness of the base station machine room itself is poor, and the insulation effect is not good, which makes the air conditioner run longer.

●The cooling efficiency of the air conditioner itself decreases due to the reduction of refrigerant, and the temperature control is not accurate, which makes the air conditioner run for a long time.

●According to the design requirements, some communication base stations are equipped with two air conditioners, one master and one backup, in order to ensure the safe operation of base station equipment, resulting in idle equipment and waste of investment.

Due to the failure of air-conditioning equipment, the temperature of the base station equipment room rose rapidly, resulting in outage.

Air-cooled equipment is also used in other fields, but there are problems of self-cleaning and good dust removal.

As the air drawn in by the ventilator reaches 3000-4000 cubic meters per hour, the amount of dust that enters is astonishing, especially in the northern region, which poses a great threat to the equipment in the computer room. Therefore, it is very important to filter and remove dust before the cold air enters.

The filtration and purification of dust in the air is generally achieved through a dust removal system. There are many types of dust removal systems, such as filter screen or filter element dust removal, bag dust removal, water dust removal, electrostatic dust removal, cyclone dust removal, etc. These dust removal systems work well, but they must be used in certain environments and conditions. Such as sponge or non-woven filter dust removal system, although the filter has a certain dust holding capacity, it must be cleaned regularly or replaced with a new sponge or non-woven filter, otherwise the air intake will be greatly reduced, which will seriously affect the cooling of the cold air. The amount of entry will affect the cooling effect. The bag-type dust removal system needs many cloth bags and stretches them out, which occupies a large area, and compressed air must be blown on the cloth bags regularly to remove the dust on the cloth bags. The structure is huge and complicated. The water dust removal system must have a flowing water source and a large sedimentation pool. These conditions are difficult to achieve for a small base station, especially in remote and desolate areas.

So far, although there is no application of self-cleaning air-cooled power-saving equipment for base stations in the market, there are no related reports in this regard.

The utility model project team has searched domestic and foreign patent documents and published periodical papers, and has not yet found reports or documents that are closely related to and identical with the utility model.

The temperature of the communication equipment room is completely isolated from the ambient temperature outside the station. Air conditioners are used to maintain the temperature inside the station throughout the year. However, the outdoor temperature in the morning and evening of winter, spring, autumn and summer is often lower than that of the computer room. The natural low temperature outside the station Resources are artificially neglected, resulting in endless waste of electric energy, resulting in increased operating costs.

When the indoor temperature drops to the set temperature, the air conditioner stops running. When the indoor temperature is higher than 35°C, the ventilation device works.

During the working process of the ventilation system, every 90 minutes, the self-cleaning dust removal system works for 20 seconds, and the air intake air filter rotates, so that the filter screen moves relative to the brush, and the brush brushes off the dust on its surface. At the same time, The air intake fan rotates in reverse and blows air outward to remove the dust on the dust net. Keep the filter at maximum ventilation.

Aiming at the large energy consumption of the air-conditioning equipment in the communication base station, the utility model is designed to use the temperature difference between the ambient temperature and the inside of the base station to adjust the ventilation, effectively reducing the power consumption of the air-conditioning equipment in the communication base station, and aiming at the dust removal problem existing in the actual trial. The self-cleaning air intake device effectively solves the problem of dust removal in the ventilation process and regular maintenance of equipment.

The realization of the utility model also lies in that the rotatable barrel-shaped support is a grid mesh structure, on the one hand, it is a good support for the filter net, so that the rotation is uniform and stable; and the permeability of the ventilation is guaranteed.

The realization of the utility model also lies in that the filter screen is 180～250 orders. Through experience and experiments, various dust and dirt in the air can be effectively filtered and removed.

The realization of the utility model also lies in that the filter screen is a metal net or a nylon net.

The utility model designs self-cleaning air-cooled power-saving equipment for the base station, fully and effectively utilizes natural air at a lower temperature in different seasons, different environments, and different periods of time outdoors. The air inlet device and the air outlet device are reasonably installed, especially the self-cleaning air inlet and dust removal device installed in the air inlet device, so that the brush and the motor reverse and act on the air filter at the same time, achieving a good effect of dust removal. The maintenance amount of dust removal equipment is reduced, and the heat dissipation requirements of the base station equipment room are met. As a result, the operating time of the air conditioner compressor is greatly reduced, and even the air conditioner does not need to be turned on, which significantly reduces the consumption of electric energy. It effectively solves the heat dissipation problem of the communication base station computer room from the high-density electronic components, and also plays the role of filtering air, purifying the air and air circulation in the base station.
