Description
Technical field
The present invention relates to heat abstractor technical field, and in particular to a kind of totally-enclosed current collection ring cooling structure.
Background technology
For motor when carrying out energy conversion, some total loss is transformed into heat, and it must pass through motor housing and week
The medium enclosed constantly distributes heat, and this dissemination process is the cooling of motor.The type of cooling of motor generally comprises nature
Cooling, forced air cooling, wind are air-cooled, wind water cooling, water cooling.For air-cooled, it is that blower fan is disposed with around motor, passes through air
Fluxion strap walks motor housing and the heat of surrounding, accelerates the radiating of motor, motor is quickly cooled down, this is an advantage over natural cooling
A kind of mode.
But because, along with dust, or even water, blower fan directly advertises motor easily by air in air in workshop
In dust be blown into motor, dust or water smoke prolonged stay in motor, reduce collector ring insulating properties, to the gap location of motor
Cause to block, be not easy to the radiating of motor；Dust is trapped at the cooperation of motor part simultaneously, influences matching somebody with somebody between parts
Close, also accelerate the abrasion between part.
The content of the invention
The invention is intended to provide a kind of totally-enclosed current collection ring cooling structure, with avoid it is air-cooled during air-flow and motor it is straight
Contact, motor is set to enter ash or water inlet.
Totally-enclosed current collection ring cooling structure in this programme, for the cooling of motor, including the heat conduction dress being connected with motor
Put, in addition to ring cold house, heat dissipation chamber, circulate in the wind machine and outer circulation blower fan, the ring cold house are arranged in heat dissipation chamber, interior circulation
Blower fan and outer circulation wind turbine layout are in the outside of heat dissipation chamber；Circulation air path is provided with ring cold house, heat-transfer device is located at the circulated air
In road, the air outlet of circulate in the wind machine is connected by airduct with circulation air path；Heat dissipation chamber is provided with opening, outer circulation wind turbine layout
In the opening, the air outlet face ring cold house of outer circulation blower fan.
Beneficial effect:Caused heat passes to ring cold house to motor by the heat-transfer device being attached thereto in the process of running
Interior air so that the air themperature rise of ring cold house, interior circulation motor are continuously blown into air into ring cold house so that air
Quickly circulated in the circulation air path of ring cold house, the flowing of air can speed up the radiating of heat-transfer device；In ring cold house
High temperature air transfer heat to the wall of ring cold house, heat is delivered to outer wall from inwall, and outer circulation blower fan is continuously advertised, added
Air flow in fast heat dissipation chamber, the air in heat dissipation chamber takes away rapidly the heat in ring cold house, and hot-air is excluded to radiate
Room, realize whole cooling procedure.The program completely cuts off motor and outer blower fan completely, avoids flowing into for motor surrounding air
Inside motor collecting ring, prevent dust or water from entering motor, motor is caused to block, influences radiating effect, while make collector ring
Insulating properties reduce, and the program also eliminated the possibility of dust abrasion parts, extend the service life of motor.
Further, the both sides of the heat dissipation chamber are all provided with exhaust outlet, and exhaust outlet is provided with some deflection plates, and deflection plate will be logical
The front in air port is blocked, and is left backwards to the narrow air port of heat dissipation chamber.Deflection plate deflection plate.Deflection plate blocks to ventilating opening, energy
It is enough as much as possible that wind is trapped in heat dissipation chamber, the current rate in heat dissipation chamber is improved, is easy to air to fully absorb ring cold house
Heat on wall.
Further, dust arrester is connected with the airduct between the circulate in the wind machine and ring cold house, is reduced in air certainly
The dust of band, operation of the excessive dust to heat-transfer device and other parts in ring cold house is avoided to impact.
Further, the opening where the outer circulation blower fan is provided with netted fan housing, avoids outer circulation blower fan and the external world
Direct contact, it is safer.
Further, the outer circulation blower fan is exhaust blower, and exhaust blower directly suctions out the hot-air in heat dissipation chamber, relative to
Then air blower air intake excludes from the other end, radiating effect is more preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the totally-enclosed current collection ring cooling structure embodiment of the present invention；
Fig. 2 is Fig. 1 left view structural representation；
Fig. 3 is Fig. 1 overlooking the structure diagram.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Circulate in the wind machine 1, dust arrester 11, ring cold house 2, heat dissipation chamber 3, folding
Flowing plate 31, outer circulation blower fan 4, fan housing 41.
Embodiment is basic as shown in accompanying drawing 1, Fig. 2 and Fig. 3：
Totally-enclosed current collection ring cooling structure in this programme, for the cooling of large-size machine, including what is be connected with motor lead
Thermal, in addition to ring cold house 2, heat dissipation chamber 3, circulate in the wind machine 1, outer circulation blower fan 4, ring cold house 2 is interior to be presented circulation air path shape,
In the circulation air path, the air outlet of circulate in the wind machine 1 is connected heat-transfer device by airduct with ring cold house 2.
Ring cold house 2 is arranged in heat dissipation chamber 3, and outer circulation blower fan 4 is arranged on the opening in the heat dissipation chamber 3, outer circulation wind
The air outlet face ring cold house 2 of machine 4.Opening where outer circulation blower fan 4 is provided with netted fan housing 41, avoids outer circulation blower fan
4 and extraneous direct contact, it is safer.Outer circulation blower fan 4 is exhaust blower, and exhaust blower is directly by the hot-air in heat dissipation chamber 3
Suction out, excluded relative to air blower air intake and then from the other end, radiating effect is more preferable.
As shown in figure 3, the both sides of heat dissipation chamber 3 are all provided with ventilating opening, left side is provided with two ventilating openings, and right side is provided with one and led to
Air port, the deflection plate 31 for avoiding heat dissipation chamber 3 and extraneous face is welded with ventilating opening, and deflection plate 31 hides the front of ventilating opening
Gear, leave backwards to the narrow air port of heat dissipation chamber 3.Deflection plate 31 blocks to ventilating opening, as much as possible can be trapped in wind
In heat dissipation chamber 3, the current rate in heat dissipation chamber 3 is improved, is easy to air to fully absorb the heat on the wall of ring cold house 2.
Dust arrester 11 is connected with airduct between circulate in the wind machine 1 and ring cold house 2, reduces the ash carried in air
Dirt, operation of the excessive dust to heat-transfer device and other parts in ring cold house 2 is avoided to impact.
Operation principle:Caused heat passes to ring cold house to motor by the heat-transfer device being attached thereto in the process of running
Air in 2 so that the air themperature rise of ring cold house 2, interior circulation motor are continuously blown into air into ring cold house 2 so that
Air quickly circulates in the circulation air path of ring cold house 2, and the flowing of air can speed up the radiating of heat-transfer device；Ring is cold
High temperature air in room 2 transfers heat to the wall of ring cold house 2, and heat is delivered to outer wall from inwall, and outer circulation blower fan 4 is continuous
To advertise, accelerate the air flow in heat dissipation chamber 3, the air in heat dissipation chamber 3 takes away rapidly the heat that ring cold house 2 avoids, and by heat
Air excludes heat dissipation chamber 3, realizes whole cooling procedure.
