Description
Technical field
This utility model relates to a kind of cooling devcie of motor.Specifically, it is the hollow cooler utilizing cold air that operating motor is cooled down.
Background technology
Producing and application both knows about at motor, winding motor volume is big, power is high, and in running, its electric energy can produce loss during being converted into mechanical energy, and this loss is then converted to heat energy, makes that the motor feels hot.If not carrying out active cooling, the time one is long, and heat may proceed to raise so that winding motor works long hours at a higher temperature.So, the service life of winding motor can be shortened.Therefore, it is necessary for winding motor is taked cooling provision.At present, the method for winding motor cooling is mainly arranged hollow cooler on winding motor.This hollow cooler includes the shell of the approximation cuboid in lateral arrangement, and there is closing plate shell one end, has inner hole plate, have, between inner hole plate and closing plate, the cold air chamber entered for cold air in the neighbouring shell closing plate.The other end of shell has on outer orifice plate, described inner hole plate and outer orifice plate all has the pore on pore and inside and outside orifice plate corresponding, all has cooling tube between corresponding pore.Wherein, four wall lower edges of shell are concordant with the base plate lower surface of shell.When motor runs, electric energy the consumption produced during being converted into mechanical energy says that the heat energy formed is then converted to hot blast, enters in the shell between inner hole plate and outer orifice plate, carries out heat exchange with cooling tube, make cooling tube generate heat.Cold air enters back into after entering cold air chamber by air-introduced machine and flows through cooling tube, and after carrying out heat exchange with cooling tube, the cooling tube one end on outer orifice plate is discharged, and realizes the cooling to winding motor with this.Owing to being provided only with cooling tube between inner hole plate and outer orifice plate, it is impossible to be internally formed closed circuit at winding motor.Therefore, using above-mentioned chiller to cool down winding motor, cooling effect is poor, it is difficult to meets the cooling requirement of winding motor, thus can shorten the service life of winding motor.Again can be dirty along shell four wall due to the rainwater on four wall lower casing top boards of shell, thus further shorten the life-span of motor.
Utility model content
Problem to be solved in the utility model is to provide a kind of cooler of electric motor.This cooler, good cooling results.Use this cooler, the service life of winding motor can be extended.
The problems referred to above to be solved in the utility model are realized by techniques below scheme:
Cooler for motor of the present utility model includes the shell of the approximation cuboid in lateral arrangement, and there is closing plate shell one end, has inner hole plate, have, between inner hole plate and closing plate, the cold air chamber entered for cold air in the neighbouring shell closing plate.The other end of shell has on outer orifice plate, described inner hole plate and outer orifice plate all has the pore on pore and inside and outside orifice plate corresponding, all has cooling tube between corresponding pore.It is characterized in the shell between inner hole plate and outer orifice plate having the first dividing plate and second partition, by the first dividing plate and second partition, inside and outside orifice plate being separated into the first hot air chamber, the second hot air chamber and the 3rd hot air chamber, the first hot air chamber, the second hot air chamber and the 3rd hot air chamber are all connected with cooled motor cavity.First hot-blast outlet, the second hot wind inlet and the 3rd hot-blast outlet are arranged respectively at the bottom of the first hot air chamber, the second hot air chamber and the 3rd hot air chamber.Described first dividing plate corresponding with inside and outside orifice plate is easy to the pore that cooling tube passes with all having on second partition；The top board of described shell is middle higher than its longitudinal both sides, and four walls of shell the most all have the lower chimb for covering cooled motor.
Further improvement of the utility model scheme is, less than its inner edge outside the part sheath top plate corresponding with cold air chamber so that the inclined layout of this partial panels.
Further improvement project of the present utility model is, closely shape is arranged into cross section to described cooling pipe in the enclosure is inversed W-shape.
As can be seen from the above scheme, owing to having the first dividing plate and second partition in the shell between inner hole plate and outer orifice plate, by the first dividing plate and second partition, inside and outside orifice plate is separated into the first hot air chamber, the second hot air chamber and the 3rd hot air chamber, all outer with the cooled motor intracavity inter-connection of the first hot air chamber, the second hot air chamber and the 3rd hot air chamber.First hot-blast outlet, the second hot wind inlet and the 3rd hot-blast outlet are arranged respectively at the bottom of the first hot air chamber, the second hot air chamber and the 3rd hot air chamber.Described first dividing plate corresponding with inside and outside orifice plate is easy to the pore that cooling tube passes with all having on second partition.When motor runs, electric energy the consumption produced during being converted into mechanical energy says that the heat energy formed is then converted to hot-air, under the internal fan of motor drives, is initially formed interior circulation wind path.Send in the 3rd hot air chamber by the second hot wind inlet of outer casing bottom and flow to cooling tube again, after cooling tube is heated, forming heat exchange, flow through the first hot air chamber and the first hot-blast outlet from the tapping of the first dividing plate, enter in motor, circulation wind path in being formed.Meanwhile, the cold wind having the external fan of motor to blow out enters in cooling tube after the cold wind import bottom cold air chamber, cold air chamber, is taken away by the heat on cooling tube, thus completes heat exchange.As can be seen here, this utility model is by arranging the first dividing plate and second partition, change the trend of the hot blast entered in shell, extend heat in the enclosure with the heat-exchange time of cooling tube, thus improve cooling effect, meet the cooling requirement of winding motor, extend the service life of winding motor.Middle higher than its longitudinal both sides due to the top board of described shell again, four walls of shell the most all have the lower chimb for covering cooled motor, not only rainwater will not remain on top board, and beat the rainwater in sheath top plate can be dirty along shell four wall, compared with background technology, avoid the possibility entering motor along the rainwater that shell four wall is dirty, thus the life-span of motor can be extended further.
