Description
Technical field
The utility model is related to cooling tower, and in particular to a kind of centrifugal fan low noise cooling tower.
Background technology
Cooling tower is, as circulating coolant, heat dissipation to be absorbed from a system into air, to reduce water temperature with water
Device；It is to carry out cold and hot exchange after contacting with air flow using water to produce steam that its is cold, and steam volatilization is taken away heat and reached
The principles such as evaporative heat loss, convection heat transfer' heat-transfer by convection and radiant heat transfer reduce water temperature to disperse the waste heat produced in industrial or refrigeration air-conditioner
Evaporating radiator, to ensure the normal operation of system.Blower fan in mechanical-draft cooling tower is the core component of cooling tower
One of, the cooling capacity of the good and bad direct relation complete machine of its performance, mechanical-draft cooling tower typically all uses axial fan.
Utility model content
Technical problem to be solved in the utility model is to be directed to the above-mentioned state of the art, and provides a kind of EC centrifugal fans
Low noise cooling tower, its EC centrifugal fan is the centrifugal fan using digitlization brushless direct-current external rotor electric machine.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：
A kind of EC centrifugal fans low noise cooling tower, including cooling shell, EC centrifugal fans, water collection device, water distribution
Pipe, filler, water inlet pipe, outlet pipe, blow-off pipe, air-inlet window, it is characterised in that：The EC centrifugal fans are arranged at outside cooling tower
The top of shell, the bottom of the cooling tower shell side is provided with outlet pipe, water distributor, blow-off pipe, the blow-off pipe and moisturizing
Pipe is disposed in parallel in the one end at cooling shell base angle.The another side of the cooling shell is provided with air-inlet window, for the external world
Air can be supplemented into cooling tower in time, and filler, water distributor and water collection device are provided with the cooling tower, and the filler, which is fixed, to be put
It is placed on the stuffing frame in cooling tower, the water distributor is set in parallel in above filler, after blower fan is opened, the air-inlet window is inhaled
The air entered first by filler, then after water collection device and blower fan from cooling tower top discharge.The water distributor is used for fanman
Recirculated water is passed into and is uniformly arranged in after cooling tower spray head on filler when making, and the recirculated water is flowed into after filler by air
Cooling falls into the base that catchments, then by outlet pipe into cooling device is needed, so circulation.
Further, the EC centrifugal fans employ digitlization brushless direct-current external rotor electric machine, and in rotor
On install centrifugal fan additional.
Further, the EC centrifugal fans use permanent magnet excitation, eliminate the generation of induction machine exciting current
Loss, compared to the axial flow blower commonly driven by threephase asynchronous, with higher efficiency；Other brshless DC motor
Excitation field does not need the reactive current of power network, therefore its power factor is far above induction machine, and brshless DC motor can be transported
Row is in 1 power factor, and this is extremely advantageous to low-power machine.Brushless electric machine compared with induction machine not only nominal load when have
Higher efficiency and power factor, and it is more advantageous in underloading.
Further, not only speed regulating control is simple for the EC centrifugal fans brshless DC motor, and with more preferable
Speed adjusting performance, therefore cooling tower has abandoned common gear reduction unit, belt reducer.
The beneficial effects of the utility model are：Compared to conventional one cooling tower, the cooling of this EC centrifugal fans low noise
The small, power factor of tower loss is high, simple in construction, easy to control, and operation noise is low.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
A kind of EC centrifugal fans low noise cooling tower of the present utility model, including cooling shell, EC centrifugal fans
1st, water collection device 2, water distributor 3, filler 4, water inlet pipe, outlet pipe 5, blow-off pipe 7, air-inlet window 8, EC centrifugal fans 1 are arranged at cold
But the top of shell, the bottom of cooling tower shell side is provided with outlet pipe 5, filling pipe 6, blow-off pipe 7, wherein blow-off pipe 7
The one end at cooling shell base angle is disposed in parallel in filling pipe 6.The another side for cooling down shell is provided with air-inlet window 8, is used for
Outside air can be supplemented into cooling tower in time, and filler 4, water distributor 3 and water collection device 2 are provided with cooling tower, and filler 4, which is fixed, to be put
It is placed on the stuffing frame in cooling tower, water distributor 3 is set in parallel in the top of filler 4, after blower fan is opened, what air-inlet window 8 was sucked
