Abstract
The utility model discloses a motor liquid cooling system, relates to the field of motor cooling technology, and aims to fully solve the liquid heat radiation problem of parts in the motor. The system comprises a housing (1), a stator (2), a rotor (3), an end cap (4), a shaft (5), a bearing (6), a bearing chamber (7), a liquid storage groove (8), a liquid outlet (9), a liquid pipeline (10), a liquid outer circulation device (11), a liquid inlet (12), a liquid distribution box (13), an injection pipeline (14), a protrusion (15) and a jet orifice (16). The liquid is jetted near the bearing (6) via the jet orifice (16), after the bearing (6) is cooled, the liquid is jetted onto the rotor (3), a vortex is formed under the joint rotation effects of the rotor (3), the shaft (5) and the bearing (6), a fully cooling effect is realized, and then the liquid is thrown towards other positions of an internal cavity of the motor. The system is mainly used for heat radiation of rotation structures composed of bearings and shafts, such as the motor.
Description
Technical field
The utility model relates to motor cooling field, is specifically related to a kind of motor liquid cooling system.
Background technology
The prior motor Cooling Design generally adopts natural air cooled, air blast cooling, three kinds of modes of liquid cools, and wherein the liquid cools mode is fit to high efficiency and heat radiation is carried out in the inside of heavy-duty motor, has obtained extensive use.
But still there is following defective in prior motor liquid cooling radiating mode:
1, the end of motor stator winding generally is positioned at the air chamber of stator both sides, and temperature is very high, is difficult to obtain the better fluid cooling, so break down easily, the winding that especially is positioned at motor circumference upside is all the more so, often burns out.
2, the liquid cools mode that has is not passed through near the bearing, can not fully cool off or even lubricate bearing.Bearing length time high speed rotating, failure rate is higher, and the life-span is shorter.
3, near the adstante febre bearing causes easily and the fitness variation of bearing chamber, bearing and axle causes the wearing and tearing of bearing chamber and axle then, and it is bigger to repair difficulty.
4, the liquid cools mode that has promptly allows to emphasis and sprays these positions, but is difficult to the heat at a stator and a middle part that constitutes is fully taken away.
Do not see yet in the market, dispel the heat for winding well, can take away stator, the more heats in rotor middle part again, and give bearing lubrication, give the fully cooling of bearing, bearing chamber, axle, the motor Control device of liquid cooling that adaptability is stronger.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide never see on a kind of market can overcome these defectives, function practicality, functional, can fully dispel the heat to each position of motor, motor respectively be rotated the motor liquid-cooling system of position sufficient lubrication.
The utility model adopts following technical proposals:
A kind of motor liquid cooling system, comprise housing 1, stator 2, rotor 3, end cap 4, axle 5, bearing 6, bearing chamber 7, liquid storage groove 8, liquid outlet 9, fluid pipeline 10, liquid external circulating device 11, liquid inlet 12, also be provided with jet 16, described jet 16 can be arranged on the wall of described bearing chamber 7.
Also be provided with projection 15, described projection 15 is connected on the inner face of described bearing chamber 7 sidewalls.
Described jet 16 can be arranged in the described projection 15.Described jet 16 can eject cooling liquid at this.
Described jet 16 also can be arranged on the inwall of described bearing chamber 7 bottoms.Described jet 16 also can eject cooling liquid at this.
Also be provided with injection pipe 14; Described injection pipe 14 is positioned at the surperficial or inner of described end cap 4; Also be provided with liquid distributor disk 13; Described liquid distributor disk 13 is connected between described liquid inlet 12 and the described injection pipe 14, to play the effect of fluid cushion and distribution.
Cooling liquid can provide sufficient cooling and lubricates after near the ejection described bearing 6 for individual moving position of the inside of motor, for each quiet position of motor provides sufficient cooling.
Significant advantage of the utility model and beneficial effect are:
1, helps taking away the heat of described stator winding.
2, help taking away the heat of described rotor.
3, help taking away the heat of described bearing, axle, bearing chamber.
4, help prolonging its useful life for described bearing, axle, bearing chamber provide sufficient lubricating oil.
