Description
Technical field
This utility model relates to the air-cooled structure of a kind of cfentrifugal blower.
Background technology
The height of blower motor temperature has extremely important impact to its efficiency and service life, so phase must be taked
The cooling measure answered.Electric motor temperature reduction mode has two kinds: water-cooled and air-cooled, the most any type of cooling, reaches certain cold
But rate-of flow is the premise realizing electric motor temperature reduction.What major part motor used is all water-cooled or combination cooling, has seldom used
Full air cooling way.It is high that the advantage of water-cooled is mainly coolant specific heat capacity, and cooling rate is fast, and shortcoming is that auxiliary device is many, needs to join
The adnexaes such as standby corresponding circulating pump, fin, water tank, have certain requirement to coolant, and the cooling to rotor is imitated
The most inconspicuous.The specific heat capacity of air-cooled middle air is low, and cooling rate is relatively slow, so air-cooled difficult point is how to strengthen air-cooled amount.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy to process, can strengthen the centrifugal drum of air-cooled amount
The air-cooled structure of blower fan.
This utility model adopts the following technical scheme that
This utility model includes fan box, the dividing plate being fixedly installed in described fan box, is arranged on dividing plate
Electric machine casing, the end cap being fixedly installed on described electric machine casing end, the air-cooled set being arranged in electric machine casing, it is arranged on motor
Impeller on output shaft and be arranged on the spiral case outside impeller, a sidewall of described fan box is filter cotton plate, described end
Cover between dividing plate and filter cotton plate, described end cap arranges fresh air inlet, described electric machine casing other end sidewall is arranged out
Air port.
Axially arranged external tooth form groove on the lateral wall of air-cooled set described in the utility model, on the medial wall of described air-cooled set
Axially arranged internal tooth form groove.
Between dividing plate described in the utility model and described electric machine casing, sealing strip is set.
This utility model good effect is as follows: this utility model is easy to process, the space between dividing plate and filter cotton plate
Forming inlet plenum, when aerator runs, in fan box, air is under the effect of impeller and spiral case, with high-speed punching air-out cabinet
Body, causes the pressure in fan box to decline.Owing to now ambient exterior atmospheric pressure is higher than fan box internal pressure, at this pressure reduction
Effect under, extraneous air enters into inlet plenum by filter cotton plate, enters into motor casing by the fresh air inlet on electric motor end cap
The inside of body, owing to arranging inside and outside serrate slot on the inside and outside sidewall of air-cooled set, substantially reduces air inside electric machine casing
Resistance during flowing, maintains the Effec-tive Function of aerator, and this utility model flows through the air quantity of motor and reached maximum, motor
Cooling air quantity be the flow of aerator.Meanwhile, for aeration blower, this structure is also associated with power of motor: drum
When blower fan height rotating speed runs, power of motor is big, and air-cooled amount is big；When the aerator slow-speed of revolution runs, power of motor is little, and air-cooled amount is little.
This utility model is all significantly improved without excessive parts, economy and reliability.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation；
Accompanying drawing 2 is this utility model air-cooled nested structure schematic diagram；
Accompanying drawing 3 is this utility model air-cooled work process structural representation；
Accompanying drawing 4 is this utility model electric machine casing and end cover structure schematic diagram.
In the accompanying drawings: 1 filter cotton plate, 2 fan box, 3 dividing plates, 4 end caps, 5 electric machine casings, 6 air-cooled sets, 7 impellers, 8 snails
Shell, 9 external tooth form grooves, 10 internal tooth form grooves, 11 fresh air inlets, 12 air outlets.
Detailed description of the invention
As shown in accompanying drawing 1,2,3,4, this utility model includes fan box 2, is fixedly installed in described fan box 2
Dividing plate 3, the electric machine casing 5 being arranged on dividing plate 3, it is fixedly installed on the end cap 4 of described electric machine casing 5 end, is arranged on motor
Air-cooled set 6, the impeller 7 being arranged on motor output shaft in housing 5 and be arranged on the spiral case 8 outside impeller 7, described blower fan
One sidewall of casing 2 is filter cotton plate 1, and the lateral wall axle of described air-cooled set 6 sets up external tooth form groove 9, at described air-cooled set 6
Medial wall on axially arranged internal tooth form groove 10；Internal tooth form groove 10 contacts with stator, can be straight by the air of internal tooth form groove 10
Connecing stator cooling, eliminate the process of conduction of heat, external tooth form groove 9 increases the surface area of air-cooled set 6, and cooling efficiency is further
Improve, meanwhile, the external tooth form groove 9 of air-cooled set 6 setting and internal tooth form groove 10, substantially reduce air at electric machine casing 5 internal flow
Resistance time dynamic, maintains the Effec-tive Function of aerator.
Described end cap 4 is between dividing plate 3 and filter cotton plate 1；Fresh air inlet 11, described motor casing are set on described end cap 4
Air outlet 12 is set on body 5 other end sidewall, between described dividing plate 3 and described electric machine casing 5, sealing strip is set.
Space between this utility model dividing plate 3 and filter cotton plate 1 is the inlet plenum of aerator, when aerator runs,
In fan box 2, air is under the effect of impeller 7 and spiral case 8, with high-speed punching blowing machine casing 2, causes the pressure in fan box 2
Power declines.Owing to now ambient exterior atmospheric pressure is higher than fan box 2 internal pressure, under the effect of this pressure reduction, extraneous air leads to
Cross import filter cotton 1 and enter into inlet plenum, entered into the inside of electric machine casing 5 by the fresh air inlet 11 on electric motor end cap 4, now
Gas will be divided into two parts, and most gas can arrive electric machine casing 5 left end, little portion by the serrate slot on air-cooled set 6
Divide gas can arrive electric machine casing 5 left end, afterwards via the air-out on electric machine casing 5 sidewall in the gap between stator and rotor
Mouth 12 arrives the inside of fan box 2, when pressure journey Gradient distribution, through impeller 7 and the effect of spiral case 8, arrives
In outside network, so circulate.
This utility model flows through the air quantity of motor and has reached maximum, and the cooling air quantity of motor is the flow of aerator.
Meanwhile, for aeration blower, this structure is also associated with power of motor: when aerator height rotating speed runs, and power of motor is big,
Air-cooled amount is big；When the aerator slow-speed of revolution runs, power of motor is little, and air-cooled amount is little.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；
Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that:
Technical scheme described in previous embodiment still can be modified by it, or is equal to wherein portion of techniques feature
Replace；And these amendments or replacement, do not make the essence of appropriate technical solution depart from this utility model embodiment technical scheme
Spirit and scope.
