Description
Technical field
The utility model is related to a kind of motor cooling device, and in particular to one kind row hydronic motor of coolant
Cooling system.
Background technology
Existing motor carries out air-cooled by air intake mostly, and its effect is unsatisfactory.At this stage, electric automobile is more and more general
And, the stability requirement more and more higher of motor work, and over long distances, work under higher load condition, problem that the motor feels hot harm
It is very big.Only it is extremely difficult to cooling effect by air-cooled.
But existing liquid cooling motor effect is not also good, it is impossible to which motor internal is cooled down, cause temperature inside and outside motor
Difference is big, and liquid is unfavorable to work with motor stabilizing.Simultaneously because the temperature difference between motor core and shell is big, and excessively apart from end, heat
Air is carried out with cold air convection in narrow space, this can make motor produce high-frequency, the vibrations of short arc, for a long time such as
This causes to be added to volume damage to internal structure of motor.
The content of the invention
The purpose of this utility model is to provide a kind of utilization coolant to motor internal and outside while being cooled down
Circulating cooling system, improves radiating efficiency, reduces the temperature difference of motor inside and outside.
To achieve these goals, the utility model includes, a kind of to electromotor cooling system, including a shell, one
The stator being fixed on inner surface of outer cover, a rotor and a rotating shaft being installed in stator, it is characterised in that described outer
There is the coolant guiding gutter of spiral surrounding on shell；The rotating shaft is hollow shaft, there is a cavity in it；The tail end of the cavity has one
The feed tube feed tube to the head end of cavity extends, and there is an opening center of the head end of the feed tube；The tail end of the rotating shaft
There is a shaft-cup, have liquid outlet on the shaft-cup, the liquid outlet is connected with drain pipe；The guiding gutter feed liquor of the drain pipe and guiding gutter
Pipe is connected, and the guiding gutter drain pipe is connected with the feed tube in cavity；Pump is communicated with the feed tube or drain pipe.
By using hollow shaft, and force to be passed through coolant into hollow shaft, the heat band that quickly can be produced rotor
Walk, subtract the heat to stator transmission, radiating is more direct, so as to improve radiating efficiency.And coolant also passes through shell and stator is entered
Row cooling, so as to realize that set of system, to the purpose cooled down inside and outside motor simultaneously, can reduce the inside and outside temperature difference, it is ensured that motor work
That what is made stablizes.
Flow deflector is evenly distributed with the inner surface of the cavity, coolant is pushed away to cavity tail end in flow deflector rotation
Enter.The rotation of rotating shaft can promote the circulation of coolant, and coolant flow speed to be directly proportional to rotating shaft rotating speed.That is, motor work
Work meets higher, and cooling velocity is faster, so that the system possesses adaptivity.
Heat exchanger is installed on the feed tube or drain pipe.Increase heat exchanger, quickly coolant can be lowered the temperature.
The liquid outlet has multiple, while drain pipe correspondence also has multiple, connects with guiding gutter feed tube after parallel connection.It is multiple
Liquid outlet is easy to coolant to discharge, and reduces the vibrations of rotating shaft.
