Description
Technical field
The present invention relates to heat abstractor technical field, be specifically related to a kind of totally-enclosed collector ring cooling structure.
Background technology
Motor is when carrying out power conversion, and always some loss is transformed into heat, and heat constantly must be distributed by the medium of motor housing and surrounding by it, and this dissemination process is the cooling of motor.The type of cooling of motor generally comprises that nature cooling, forced air cooling, wind are air-cooled, wind water cooling, water-cooled.For air-cooled, be furnished with blower fan around motor, walked the heat of motor housing and surrounding by the fluxion strap of air, add the heat radiation of speed motor, motor is cooled fast, this is a kind of mode being better than nature cooling.
But, due in air in workshop along with dust, even water, blower fan is directly advertised motor and easily the dust in air is blown into motor, and dust or water smoke prolonged stay, in motor, reduce collector ring insulation property, shutoff is caused to the gap location of motor, is not easy to the heat radiation of motor; Dust is trapped in the cooperation place of motor part simultaneously, affects the cooperation between parts, also accelerates the wearing and tearing between part.
Summary of the invention
The invention is intended to provide a kind of totally-enclosed collector ring cooling structure, to avoid air-flow in air-cooled process to contact with the direct of motor, make motor enter ash or water inlet.
Totally-enclosed collector ring cooling structure in this programme, for the cooling of motor, comprise the heat-transfer device be connected with motor, also comprise ring cold house, heat dissipation chamber, Inner eycle blower fan and outer circulation blower fan, described ring cold house is arranged in heat dissipation chamber, and Inner eycle blower fan and outer circulation wind turbine layout are in the outside of heat dissipation chamber; Ring is provided with circulation air path in cold house, and heat-transfer device is located in this circulation air path, and the air outlet of Inner eycle blower fan is connected with circulation air path by airduct; Heat dissipation chamber is provided with opening, and outer circulation wind turbine layout is at this opening, and the air outlet of outer circulation blower fan is just to ring cold house.
Beneficial effect: the heat that motor produces in running passes to the air in ring cold house by the heat-transfer device be attached thereto, the air themperature of ring cold house is raised, Inner eycle motor continuous print is blown into air in ring cold house, air is circulated fast in the circulation air path of ring cold house, and the flowing of air can accelerate the heat radiation of heat-transfer device; High temperature air in ring cold house transfers heat to the wall of ring cold house, heat is delivered to outer wall from inwall, outer circulation blower fan is advertised continuously, accelerate the air flowing in heat dissipation chamber, air in heat dissipation chamber takes away rapidly the heat in ring cold house, and hot-air is got rid of heat dissipation chamber, realize whole cooling procedure.The program by motor and outer blower fan completely isolated, what avoid motor surrounding air flows into motor collecting ring inside, prevent dust or water from entering motor, shutoff is caused to motor, affect radiating effect, make collector ring insulation property reduce, the program also eliminated the possibility of dust wearing and tearing parts, extends the useful life of motor simultaneously.
Further, the both sides of described heat dissipation chamber are all provided with exhaust outlet, and exhaust outlet is provided with some deflection plates, and the front of ventilating opening is blocked by deflection plate, leave the narrow air port of heat dissipation chamber dorsad.Deflection plate deflection plate.Deflection plate blocks ventilating opening, can as much as possiblely be trapped in heat dissipation chamber by wind, improves the current rate in heat dissipation chamber, is convenient to air and fully absorbs heat on ring cold house wall.
Further, the airduct between described Inner eycle blower fan and ring cold house is connected with dust cleaning apparatus, reduces the dust carried in air, avoid the operation of too much dust to the heat-transfer device in ring cold house and other parts to impact.
Further, the opening at described outer circulation blower fan place is provided with netted fan housing, avoids outer circulation blower fan to contact with the direct of the external world, safer.
Further, described outer circulation blower fan is exhaust blower, and exhaust blower is directly by the hot-air sucking-off in heat dissipation chamber, and then get rid of from the other end relative to air blast air intake, radiating effect is better.
