Background technology
In communications equipment room, communication equipment generates heat throughout the year, and heat dissipation capacity is large, even still need in the winter time to adopt air conditioner refrigerating to reduce indoor temperature, guarantees the normal operation of communication equipment, and the air conditioning energy consumption brought therefrom is very large.At severe cold area, the air-conditioning system of communications equipment room must be avoided in the winter time the time in cooling water pipeline and cooling tower freezes, and generally can only increase electric tracing, solves.
Severe cold area winter is outdoor possesses a large amount of free low-temperature receiver---cold airs, if outdoor natural cooling source is introduced to the heat of eliminating room in machine room, reduce temperature in machine room, thereby reduce the Energy in use of winter air-conditioning system, can reach the purpose of saving electric energy, reducing the communications equipment room operation cost.
Severe cold area utilizes outdoor cold source to mainly contain three kinds of modes:
1) directly new wind is cooling: directly outdoor new wind being sent in machine room, when outside air temperature is hanged down, can directly outdoor Cryogenic air be delivered to indoorly, is room temperature lowering;
2) outdoor air is indirectly cooling: directly do not introduce new wind, the equipment such as employing heat exchanger are introduced outdoor cold indoor, thereby reach the purpose that indoor temperature is reduced.
3) outdoor cooling tower provides low-temperature receiver for the air-conditioning unit.
Come direct cooling room air and equipment if directly introduce outdoor new wind, need to increase High-cfficiency Filtration equipment and guarantee the requirement of communications equipment room to air purity, and sand and dust area outdoor air dustiness is higher, particularly in the winter time and the Spring Festival, screen pack very easily stops up, and not only cause maintenance cost to raise, and sand and dust stops up filtration system, the equipment that may affect normally moves, and reduces the operational reliability of refrigeration system.Generally, the method can't be used.
The cooling tower cooling need increase electric tracer heating system and guarantee operation, the corresponding increase of energy consumption.
The utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and the natural cooling-fan installation that is applicable to severe cold sand and dust area communication machine room is provided, be about to room air and carry out heat convection by exposed at outdoor airduct and outdoor cold air, air in airduct is cooling, and circulation is delivered to indoor.
In order to achieve the above object, the natural cooling-fan installation that the utility model is designed, it mainly comprises that airduct is respectively arranged with air inlet and air outlet at the two ends of airduct, described air inlet and air outlet all are communicated with indoor machine room, described airduct is arranged on outdoor, and be provided with the blower fan that airflow circulating power is provided in described airduct, and the mid portion of described airduct is the enhanced heat exchange section, described enhanced heat exchange section be airduct axially on uniform many minor diameter heat exchanger tubes.The characteristics of this structure are, utilize hot blast in outdoor lower temperature cooling duct, then the cooling cold wind completed are looped back indoorly, particularly utilize aluminum veneer airduct and minor diameter heat exchanger tube raising heat exchange efficiency.
As preferred version, described airduct inside is supported by steel structure framework, at airduct and steel structure framework construction, special rubber sheet gasket is arranged, and to improve the intensity of airduct, and reduces vibration, reduces noise.
As preferred version, between described blower fan and airduct, by the glass hose coupling, be connected, avoid the vibration of machine is directly passed to airduct.
As preferred version, described BOD is provided with condensate collector, and condensate collector is communicated with the floor drain in machine room by condensate pipe, and BOD and condensate pipe are equipped with the electric tracing thermal insulation device.To prevent frosting, the phenomenon such as freezing.
As preferred version, described airduct is of a size of 2400～2000 * 1500mm, and airduct adopts the aluminum veneer that thickness is 3mm, with the wall of communication equipment room facade, is combined, and can promote the building integral aesthetics.
As priority scheme, described minor diameter heat exchanger tube diameter is 200mm, and length is that the 8000mm arrangement mode is 7 * 7, row interval 100mm, and between-line spacing 200mm, reached the ratio optimization of heat exchange efficiency and cost of investment.
The natural cooling-fan installation that the utility model is designed, utilize outdoor lower temperature, freely lowers the temperature and reached the effect of saving the energy.Use the designed natural cooling-fan installation of the utility model, can make the temperature difference between air inlet and air outlet differ 10 ℃ of left and right, reach the desired cooling-down effect of communications equipment room fully.Also have structural strength high, the airduct vibration is little simultaneously, and noise is low, the investment characteristics that gain quick return.
