Description
Technical field
The utility model relates to the electric vehicle motor technology, is a kind of electric vehicle-mounted complete closed internal liquid cooling, external wind cooling type switch reluctance motor device specifically.This is a kind of vehicle-mounted drive motors that drives powerful, perfect heat-dissipating, the better waterproof energy is arranged.This drive motors is when running up, and cooling system can effectively be controlled temperature rise, the particularly temperature rise of switching magnetic-resistance drive motors stator winding end.
Background technology
Motor type as Drive for EV has asynchronous motor, permanent magnetic brushless and switched reluctance machines at present.The induction motors torque fluctuation is less, but efficient is lower, especially at low-speed stage; Permanent magnetic brushless efficient is higher, but the manufacturing process complexity has the demagnetization problem, and reliability is not high, and is therefore also undesirable; That switched reluctance machines has is firm in structure, reliability is high, full operating range internal efficiency height, and the advantage of low starting current and high start torque, these all are that the motor of other type is incomparable.
There are at present two problems as vehicle-mounted switched reluctance machines, first motor waterproof, it two is motor radiatings.If electric automobile adopts the front-wheel drive pattern, drive motors is positioned over the front end of car body, and motor is positioned at the power transmission shaft place, below car body, in the rainy day motor vehicle traveling process, if the road surface has ponding easily to cause fault, the water-proofing treatment of need taking measures to do improves the degree of protection of motor.In addition, if the radiating ribs of drive motors be parallel to automotive wheel axially, wind direction is along car body in the past backward in the vehicle traveling process, perpendicular to motor axially, promptly wind causes the heat radiation of motor inhomogeneous along the radial motion of motor.If the radiating ribs on the electric machine stand along motor shaft to, the radiated rib wind-engaging effect of motor forward direction is better, but influenced its back radiating ribs be subjected to air quantity, caused the heat radiation of motor inhomogeneous equally.Experiment shows, if when adopting running car fully, the windage of air movement formation is to motor radiating relatively, after electric automobile is out of service, the heat radiation of motor is dispelled the heat by conduction and radiation fully, radiating efficiency is low, very easily causes the temperature of motor to rise than higher, influences the operating efficiency and the useful life of drive motors.Switched reluctance machines has its special structure construction---and winding is concentrated, therefore often there is the especially bad problem of its end heat radiation of stator winding, the defective of bringing thus be along with rotating speed increase or the long-play of motor can cause bigger temperature rise, can reduce the operating efficiency of motor, and long-play can make stator winding insulation aging, reduces useful life.
Summary of the invention
The purpose of this utility model provides a kind of electric vehicle-mounted complete closed internal liquid cooling, external wind cooling type switch reluctance motor device, and this technology can solve the heat radiation and the waterproof problem of vehicle-mounted switched reluctance machines.
The technical solution of the utility model is as follows:
Electric vehicle-mounted complete closed internal liquid cooling, external wind cooling type switch reluctance motor heat dissipation design:
In the switched reluctance machines back, be provided with deep bead towards vehicle front.
On the inner surface of sealed enclosure, be laid with heat radiation chamber and casing heat pipe.
Stator winding end is pressed the stator tooth Shape Design.
Be provided with by cold pendular ring pipe A, Type B heat conduction forelock and that be connected with the casing heat pipe with the cooling liquid tube road at the stator winding front and back ends.
A type heat conduction wedge is the fixedly hook-shaped of bottom surface, and fixedly insert in the slit of stator winding and stator tooth end the bottom surface, and the upper end is hooked on the cold pendular ring pipe.Type B heat conduction wedge is the fixedly both wings hook-shaped of bottom surface, and fixedly insert in the slit of stator winding and stator tooth end the bottom surface, and upper end two pterygoid hamulus hold together cold pendular ring tube terminal.
Electric vehicle-mounted complete closed internal liquid cooling, the design of external wind cooling type switch reluctance motor waterproof construction:
Lid mouth, two axle heads, connection box for motor periphery and the incoming line of rotor, Inlet and outlet water port, closed position transducer place at electric motor end cap are equipped with sealing gasket, sealing ring, water proof ring, and rotor is provided with the sealing inserts.
The utility model is the special heat dissipation design that switched reluctance machines provides, and can make motor obtain interior liquid cooling and outer air-cooled dual radiating effect.。Lay heat radiation chamber and the casing heat pipe that wraps up stator winding at the sealed enclosure inner surface, flowing gas in the heat radiation chamber and the cooling fluid in the casing heat pipe can be dispelled the heat to stator winding.The heat conduction wedge reaches cold pendular ring pipe with the heat of winding overhang inboard, realizes stator winding forward and backward end heat radiation, thereby has solved the not smooth problem of stator winding heat dissipation.Because stator winding end is pressed the stator tooth Shape Design, the end winding is shorter, so save copper material.The effect of deep bead is to make the natural wind that enters vehicle produce circulation, and natural wind can be cooled off motor along deep bead, enlarges air-cooled area, when motor case the place ahead obtains heat radiation, also can make the casing rear obtain heat radiation, disperses the heat on the motor rapidly.So the utility model radiator structure can effectively reduce the temperature rise of Stators for Switched Reluctance Motors winding and winding overhang, cooling evenly improves cooling effectiveness.The waterproof construction of the utility model motor can effectively reach the purpose of motor waterproof in addition.
The torque of the utility model electric vehicle-mounted complete closed switch reluctance motor is big, dynamic property good, energy-efficient, noise is low, airtight reliable, the temperature rise when this technology can effectively be controlled motor and runs up can be controlled the temperature rise of stator winding end especially.Effectively waterproof guarantees under the situation of rainy day or surface gathered water, the motor safety operation, thus the security performance and the degree of protection of raising motor working efficiency and motor prolong its useful life.
