Description
Technical field
The present invention relates to electrical generator fields, in particular to a kind of two-way centrifugal fan applied to generator and
Its cool-down method.
Background technology
The fever of generator is a major issue that annoying generator manufacturer always, and the fever of generator studies carefully it
Reason mainly has the reason of following three aspects：1, mechanical friction is generated heat, since generator is mutually rotated with rotor by stator
Electricity is generated, in rotary course, the mechanical wear face of mounting surface and support machine will generate heat；2, electric current by stator and turns
Fever is generated when sub- conductor；3, since stator and rotor are made by ferrimagnet, ferrimagnet generates in magnetic field
The fever for being vortexed and generating.Generator is driven by the engine, during the use of generator, engine is needed constantly to work
Drive generator, in engine work it is same it is inevitable generate heat, since generator is linked together with engine,
The heat part that engine generates is discharged by the cooling system of engine, and a part passes to my generator, another part
It is gathered in motor surrounding air as heat radiation, the heat of generator is caused constantly to increase, if not in time and rapidly will
These heat produceds are gone out, and heat can be caused to assemble around generator, generator-temperature detection is promoted to increase rapidly, when temperature is more than hair
When motor utmost carrying ability, generator will burn, and gently then cause equipment damage, heavy then will produce major accident.Therefore, how to solve
The certainly heat dissipation problem of generator is that current numerous generator manufacturers necessarily solve the problems, such as.
For this purpose, many generator manufacturers will install some cooling-parts to solve the above problems in generator at present,
The current type of cooling mainly has two ways, such as air-cooled and water cooling.Wherein, water-cooling pattern is all well and good on cooling effect, but water
Cold mode but has a lot of other defects that can not solve：First, it is stator that water cooling is mainly cooling, rotor can not cool down, therefore rotor
There are still raised possibility for temperature；Second is that the hidden danger of leak electricity short-circuit, due to there is water, it is possible to there is leakage, once occur, it will
Lead to very serious accident.Therefore use the generator of water-cooling pattern seldom currently on the market.
Current air cooling way is mainly on the armature spindle by fan inside the drive end bearing bracket, and wind is from rear when generator is run
End cap enters flows to fan through generator gap, then is flowed out from drive end bearing bracket ventilation hole, this fan can only be in motor side shape
At wind flow, generator can only be reduced, the heat generated for motor periphery and engine is helpless.Although city at present
Field has arranges exhaust fan in unit periphery, but the problem of be limited by set structure, installation is limited, and air quantity is generally less than normal, cooling
It is ineffective, on the other hand by cost impact, it is difficult to be formed and be competed in market.
Invention content
In consideration of it, the present invention provides a kind of two-way centrifugal fans and its cool-down method applied to generator, it is intended to
Solve technical problem bad to the heat cooling-down effect of motor periphery and engine generation in the prior art.
