Abstract
The invention discloses a natural cooling ventilating system. The natural cooling ventilating system mainly comprises an air pipe, wherein an air inlet and air outlets are formed at the two ends of the air pipe respectively, the air inlet and the air outlets are communicated with an indoor machine room, the air pipe is arranged outdoors, a fan which provides power for air current circulation is arranged in the air pipe, a heat exchange enhancement section is arranged in the middle of the air pipe, and the heat exchange enhancement section is formed by evenly distributing a plurality of small-diameter heat exchange tubes in the axial direction of the air pipe. According to the structure, the natural cooling ventilating system is characterized in that the lower outdoor temperature is used for cooling indoor hot air, cold air after accomplishment of cooling is circulated to enter the machine room, and particularly the small-diameter heat exchange tubes are used for improving heat exchange efficiency. According to the natural cooling ventilating system, the difference between the temperature of the air inlet and the temperature of each air outlet can be about 10DEG C, the cooling effect required by the telecommunication machine room can be completely achieved, and the natural cooling ventilating system further has the advantages of being high in structural strength, low in vibration of the air pipe, low in noise and rapid in investment recovery.
Description
Technical field
The present invention relates to a kind of cooling-fan installation, particularly a kind of natural cooling-fan installation.
Background technology
Communication equipment generates heat throughout the year in the communications equipment room, and heat dissipation capacity is big, even still need to adopt air conditioner refrigerating to reduce indoor temperature in the winter time, guarantees the normal operation of communication equipment, and the air conditioning energy consumption that brings therefrom is very big.At severe cold area, the air-conditioning system of communications equipment room must be avoided in the winter time the time in the cooling water pipeline and cooling tower freezes, and solves and generally can only increase electric tracing.
Severe cold area winter is outdoor to possess a large amount of free low-temperature receiver---cold airs, if outdoor natural cooling source is introduced the heat of eliminating the room in the machine room, reduce temperature in the machine room, thereby reduce the use energy consumption 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 air cooling: directly outdoor new wind is sent in the machine room, when outside air temperature is hanged down, can directly outdoor Cryogenic air be delivered to indoorly, be room temperature lowering;
2) outdoor air cools off indirectly: directly do not introduce new wind, 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.
Directly cool off room air and equipment if directly introduce outdoor new wind, need to increase high efficiency filter equipment and guarantee that communications equipment room is to the requirement of 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 influence normally moves, and reduces the operational reliability of refrigeration system.Generally, this method can't be used.
The cooling tower cooling need increase electric tracer heating system and guarantee operation, the corresponding increase of energy consumption.
Summary of the invention
The objective of the invention is provides the natural cooling-fan installation that is applicable to severe cold sand and dust area communication machine room for the deficiency that solves above-mentioned technology, be about to room air and carry out heat convection by exposing at outdoor airduct and outdoor cold air, with the cooling of the air in the airduct, circulation is delivered to indoor.
In order to achieve the above object, the natural cooling-fan installation that the present invention is designed, it comprises that mainly 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 the air-flow circulation power is provided in the 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 the outdoor lower temperature cooling duct, and the cold wind that cooling is finished loops back indoorly then, particularly utilizes aluminum veneer airduct and minor diameter heat exchanger tube to improve 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 with the intensity of raising airduct, and reduces vibration, reduces noise.
As preferred version, be connected by the glass hose coupling between described blower fan and the airduct, 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 floor drain in the machine room by condensate pipe, and BOD and condensate pipe are equipped with the electric tracing thermal insulation device.To prevent frosting, phenomenon such as freezing.
As preferred version, described airduct is of a size of 2400～2000 * 1500mm, and it is the aluminum veneer of 3mm that airduct adopts thickness, is combined with the communications equipment room external wall elevation, can promote the building integral aesthetics.
As priority scheme, described minor diameter heat exchanger tube diameter is 200mm, and length is 7 * 7 for the 8000mm arrangement mode, and row are 100mm at interval, and between-line spacing 200mm has reached the ratio optimization of heat exchange efficiency and cost of investment.
The natural cooling-fan installation that the present invention is designed is utilized outdoor lower temperature, and freely lowering the temperature has reached the effect of energy savings.Use the designed natural cooling-fan installation of the present invention, can make that the temperature difference between air inlet and the air outlet differs about 10 ℃, reach the desired cooling-down effect of communications equipment room fully.Also have the structural strength height simultaneously, the airduct vibration is little, and noise is low, the investment characteristics that gain quick return.
