Cooling tower is a kind of with water-cooled device, and water carries out heat exchange with the air of process therein, causes water temperature to descend; It is widely used in air-conditioner circulating water system and the industrial circulation.Heat exchange is that heat conducts to the lower air of temperature from the higher water of temperature owing to the temperature difference of water and air; And exchange is because the disconnected ground of the water vapour water that the surface evaporation of water forms spreads in air, simultaneously water vapor latent heat is brought into air.So the heat that water distributes in the evaporative cooling process is made of i.e. contact heat radiation (conduction and convection) and evaporative heat loss two parts.
Using the cooling tower purpose is the cooling-down effect that reaches certain, and the factor that impact is conducted heat depends primarily on fin, fan delivery, cooling tower Water usage, and good ventilation condition, and also there is certain impact the installation site.Wherein fan delivery is the factor of an outbalance, and its Main Function is that the accelerated tower Air flows, and accelerates the heat of air and water, takes away heat.Affecting fan delivery mainly is that the fan blade shape is the wide length of fan blade and fan blade rotating speed, setting angle, rotating speed and motor and gearratio etc. are arranged partially itself.
Yet, present cooling tower often sends larger noise when work, when the research staff has the cooling tower of high cooling efficiency more in continuous research and development design, have to cooling tower is carried out certain noise reduction process, common mode is at some sound arresters of cooling tower outer setting or material etc., does not consider cooling tower itself is improved.In addition, during the cooling tower running, its noise source mainly contains the following aspects: 1, fan noise, and its noise mainly is comprised of mechanical noise and flow noise; 2, noise of motor, the electromagnetic sound during its main motor rotation; 3, water droplet noise; 4, ventilation noise, it mainly contains tower body inner air and outer air flow noise and tower body resonance noise.As seen, the blower fan system of cooling tower is a large noise source.
As shown in Figure 1, existing cooling tower structure, comprise tower body 3, ventilating duct 1 and blower fan 2, blower fan 2 is located in the ventilating duct 1, ventilating duct 1 is located at tower body 3 tops, usually since the Zhou Jing of tower body 3 than ventilating duct 1 large (that is, the ventilating duct of tower body 3 inside is wider than the ventilating duct of ventilating duct 1), blower fan 2 often needs higher running speed, the air quantity of guarantee tower body 3 inside.Yet when blower fan 2 rotating speeds were higher, its noise also will strengthen fast, and in order to address this problem, the common practice of now a lot of enterprises is to make a muffler on ventilating duct again, to reduce noise to the impact of surrounding environment.
The utility model content
The purpose of this utility model is as addressing the above problem, thereby a kind of environment-friendly type cooling tower is provided, and has power output and reduces, realizes super low noise operation and the convenient advantage of transforming old cooling tower.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of environment-friendly type cooling tower comprises tower body, ventilating duct and blower fan; Described ventilating duct is connected on the described tower body, and described blower fan is located in the ventilating duct, and described blower fan diameter is not less than the diameter of described tower body.
Further, described ventilating duct and described blower fan are located at the top of described tower body.
Further, inwardly shrink at the junction surface of described tower body and ventilating duct, forms a narrow and small neck.
Further, described tower body and ventilating duct form at the junction surface and removably connect.
Because the fan blade diameter is not less than the diameter of tower body, thereby blower fan can move than under the slow-speed of revolution, make cooling tower under the situation that does not reduce thermal performance, arrive and reduce power output and realize the super low noise operation, transformation space and the expense of regulation cooling tower buzz have greatly been saved, because environment-friendly type cooling tower need not carry out after-treatment for the cooling tower noise again, has not only reduced production cost.Reach simultaneously the effect of energy-saving and emission-reduction.

The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described further:
As shown in Figure 2, a kind of environment-friendly type cooling tower comprises tower body 3, ventilating duct 1 and blower fan 2; Ventilating duct 1 is connected on the tower body 3, and blower fan 2 is located in the ventilating duct 1, and blower fan 2 diameters are not less than the diameter of tower body 3.
Axle centered by the rotating shaft of definition blower fan, cooking tangent plane along the vertical direction of central shaft is radial section.So, when the radial section of tower body 3 was circle, the diameter of tower body 3 was interpreted as this diameter of a circle; When tower body 3 when being irregularly shaped along radially tangent plane, such as quadrangle or polygon, the diameter of tower body 3 be interpreted as this irregularly shaped minimum circumscribed circle diameter.
Because the noise that blower fan produces and the rotating speed of blower fan have direct relation.When rotation speed of fan reduced, noise also just and then diminished.And can follow the wind for the air quantity that tower body the offers diameter of machine of blower fan has direct relation, and when the diameter of blower fan is larger, under equal rotating speed, its air quantity that can provide is also larger.Because the diameter of blower fan 2 is not less than tower body 3 diameters, thereby blower fan 2 can still can capacity supply with tower body 3 interior required air quantity than under the slow-speed of revolution, has power output and reduces, realizes super low noise operation, the convenient advantages such as old cooling tower of transforming.In addition, for further reducing noise, the week footpath of described ventilating duct 1 and blower fan 2 can be designed more greatly in OK range as far as possible.
