Abstract
The invention provides a compact water-cooling three-phase asynchronous motor, belonging to the field of motor technology, in particular to a motor cooling system. The motor cooling system has the main technical characteristic that the cooling device adopts composite cooling of air and water; the cooling system comprises an internal circulation wind passage and a water circulation passage; a water jacket is sheathed outside the stator core of the motor and consists of an internal water jacket and an external water jacket; a water passage is arranged between the internal water jacket and the external water jacket; the water passage is a radial spiral water passage or an axial reciprocating water passage; one end of the water passage is provided with a water inlet and the other end of the water passage is provided with a water outlet; the cooling water drainage passage is arranged right below the motor and connected with the water passage; a cooling wind passage is arranged between the external water jacket and the shell of the motor; and two ends of the cooling wind passage are respectively provided with a wind inlet and a wind outlet. The motor has small volume, low production cost and good heat dissipation effect, and increases the power by more than two times compared with other motors of the same volume.
Description
Technical field
The invention belongs to the motor technology field, particularly motor cooling system.
Technical background
Existing motor cooling mode has air cooling, water-cooled, empty water mixing cooling etc. multiple, but the cooling device volume is big, causes the motor volume huge, and required installing space is big, and cooling effect is poor; Existing air water cooling is motor but, and motor and cooler are two independent bodies, and cooler places the motor top, and volume is big, manufacturing cost is high; The water-cooling apparatus of existing motor does not have cooling air channel, only relies on the heat conduction cool motors stator outside, and cooling effect is poor, and no-cooling-water drains passage, has influenced motor and has used for a long time, deposits and safeguard, has shortened the useful life of motor.
Summary of the invention
The invention provides a kind of compact water-cooling three phase asynchronous motor, reduced volume, reduced manufacturing cost, improved radiating effect, prolonged the useful life of motor.
Technical scheme of the present invention is: motor comprises stator, rotor, cooling device and shell, cooling device adopts the compound cooling of empty water, circulation wind path and water circulation channel in comprising, water jacket is coated on outside the stator core in motor, is made of inner water sleeve and outer water jacket, and the centre is provided with water channel, water channel can be spiral channel radially or axial reciprocal water channel, the two ends of water channel are provided with water inlet and delivery port, and cooling water drains passage under motor, link to each other with water channel; Be cooling air channel between outer water jacket and motor casing, the cooling air channel two ends are provided with air inlet and air outlet.
Compare with background technology, compact three-dimensional asynchronous motor of the present invention is owing to adopt empty water composite cooling apparatus, and volume is little, and is cheap for manufacturing cost.The motor interior film-cooled heat increases 1.5-2 times, and radiating effect obviously improves, and increases more than 2 times than other motor power (output) of same volume.Because the bottom of inner water sleeve is provided with cooling water and drains passage, be convenient to waste water and discharge, prolonged the useful life of motor.

Fig. 2 is the side diagrammatic sketch of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, compact water-cooling three phase asynchronous motor comprises stator 3, rotor 6, cooling device and shell 4.Cooling device adopts the compound cooling of empty water, circulation wind path and water circulation channel in cooling device comprises; Water jacket is coated on outside the stator core in motor 3, constitute by inner water sleeve 7 and outer water jacket 5, the centre is provided with water channel 14, water channel can be spiral channel radially or axial reciprocal water channel, the two ends of water channel are provided with water inlet 2 and delivery port 8, cooling water drains passage 11 under motor, links to each other with water channel 14; 4 on outer water jacket 5 and shell are cooling air channels 13.
Interior circulated air route fan 10, air inlet 9, cooling air channel 13, air outlet 1 and rotor ventilation hole 12 are formed.
Water circulation channel is made up of water filling port 2, water channel 14 and delivery port 8.
The heat part that motor interior produces is passed through cross-ventilation, cooling air channel with heat through outside water jacket conduct to cooling water, dispel the heat to the motor space outerpace by motor casing simultaneously, heat on another part stator is by heat conducting form, conducted to cooling water through inner water sleeve by the motor stator sub-surface, cooling water conducts heat to outside the motor.During motor work, according to the cooling requirement, the water filling port injection pressure is the cooling water of 0.5-3Mpa, and cooling water is discharged from delivery port after absorbing heat by water channel.When motor maintenance or long-term storage, drain passage from the bottom cooling water and discharge waste water and impurity in the water jacket.
