Abstract
The utility model discloses a kind of heat-dissipating casings of alternating current generator, including outer cover body and motor cabinet, the motor cabinet is welded on the bottom of outer cover body, and installation lid and rear installation lid before the both ends of the outer cover body are installed respectively, the two sides of the outer cover body are respectively provided with several radiating ribs.By the way that air outlet is arranged in the side of outer cover body, the outer wall setting air inlet of lid is installed afterwards, since fan is mounted on the rotor inside alternating current generator, when rotor rotates forward, drive fan from air inlet air draught, it is blown out again from air outlet, form exogenous wind circulation, heat inside alternating current generator is taken away, since the arc-shaped structure of radiating ribs on air outlet is used as wind deflector, so that the wind of air outlet blowout is changed to be bent downward blowout from straight line blowout, when rotor rotates backward in this way, air outlet becomes air draught, air inlet becomes drying, dust will not be sucked inside alternating current generator.The utility model has the characteristics that thermovent effective dust.
Description
Technical field
The utility model relates to a kind of heat-dissipating casing, specially a kind of heat-dissipating casing of alternating current generator belongs to design of electrical motor
Field.
Background technique
Alternating current generator is the machinery mutually converted for realizing mechanical energy and AC energy.It is huge due to AC electric power systems
Great development, alternating current generator have become most common motor.Alternating current generator is compared with direct current generator, due to not having commutator that can lead to
The alternating current of inner rotator access is crossed to change the steering of motor shaft, therefore structure is simple, it is easily manufactured, it is easy than stronger
It is made into the motor of high revolving speed, high voltage, high current, large capacity.The coverage area of alternating current generator power is very big, from several watts to tens
Ten thousand kilowatts, even up to a million kilowatts, motor generates heat at work, therefore the shell of motor is equipped with heat release hole,
Fan is installed in inner rotator, is rotated by rotor and fan is driven to radiate.
There are still certain defects when in use for the heat-dissipating casing of existing alternating current generator, since the rotor of alternating current generator turns
To changing often, therefore the fan that rotor drives also changes direction of rotation often, therefore the thermovent on the shell of alternating current generator
It is toggled between air inlet and air outlet, and the thermovent of alternating current generator tail portion can avoid enter into ash plus filter screen
Dirt, but the radiating ribs of side wall installation can not add filter screen, therefore be easy when the hole of side wall is as air inlet to suck
Impurity damages motor internal component, and although the thermovent of alternating current generator tail portion has filter screen, but is inconvenient to seal, long
Time can also enter dust when not in use.
Utility model content
The purpose of this utility model is that solve the thermovent of the heat-dissipating casing side wall of above-mentioned alternating current generator not side
Just filter screen is added, air draught when is easy sucking impurity damage motor and does not have to dust for a long time to easily propagate through filter screen entrance
Problem inside motor and a kind of heat-dissipating casing of alternating current generator is provided, have the advantages that thermovent facilitates isolation dust.
The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of heat-dissipating casing of alternating current generator, including
Outer cover body and motor cabinet, the motor cabinet is welded on the bottom of outer cover body, before the both ends of the outer cover body are installed respectively
Installation lid and rear installation lid, the two sides of the outer cover body are respectively provided with several radiating ribs, the arc-shaped structure of radiating ribs, and two
Air outlet is set between two radiating ribs, and the size of the radiating ribs is greater than the size of the air outlet, installs before described
Bearing holder (housing, cover) is arranged in the center of lid, installs lid after described and is made of heat dissipating housing and rotor plate, and the outer wall setting of the heat dissipating housing is several
A air inlet, the inside of the air inlet are laid with filter screen, and the outer wall of the rotor plate is arranged several intercommunicating pores, and described turn
Threaded rod is arranged in the center of movable plate, and the threaded rod runs through the center of the heat dissipating housing, is between the rotor plate and heat dissipating housing
Rotation connection.
Preferably, the preceding installation lid, rear installation cover and are connected by several fixing bolts with the outer cover body.
Preferably, one end outer wall that the threaded rod passes through heat dissipating housing covers connected nut, sets between the nut and heat dissipating housing

Preferably, the size of the air inlet and intercommunicating pore is equal sized, and rotor plate is fitted in the inside of heat dissipating housing.
Preferably, the radiating ribs are curved plate, and width successively becomes smaller several radiating ribs from top to bottom.
Preferably, the radiating ribs are welded on the top of air outlet, and the bottom phase of the bottom end of radiating ribs and air outlet
In parallel.
Compared with prior art, the utility model has the beneficial effects that
1, by the way that air outlet is arranged in the side of outer cover body, air inlet is arranged in the outer wall of rear installation lid, since fan is pacified
On the rotor inside alternating current generator, when rotor rotates forward, drive fan from air inlet air draught, then blow out from air outlet,
Exogenous wind circulation is formed, the heat inside alternating current generator is taken away, since the arc-shaped structure of radiating ribs on air outlet is as wind-guiding
Plate uses, so that the wind of air outlet blowout is changed to be bent downward blowout from straight line blowout, when such rotor rotates backward, air outlet
Become air draught, air inlet becomes drying, and will not suck dust inside alternating current generator.
2, the utility model is easy to use, compact-sized, by covering setting heat dissipating housing and rotor plate, rotation in rear installation
Plate welds adjusting rod on the threaded rod of heat dissipating housing, rotor plate rotation can be stirred by adjusting rod, when the company on rotor plate
When through-hole is overlapped with air inlet, air inlet can be with air draught, and when the intercommunicating pore on rotor plate is staggered with air inlet, rotor plate is solid
Air inlet is blocked in part, so that heat dissipating housing is sealed, it, can be by way of covering air inlet when alternating current generator storage
It avoids the dust from entering along the filter screen of air inlet the inside of alternating current generator, can effectively completely cut off dust.
