Description
Technical field
The present invention is about a kind of casing assembly, espespecially a kind of motor housing component for having dual-cooled runner.
Background technique
Motor is generally used device, can make motor with output power, or pass through other energy as generator
The mode of conversion is measured to provide electric power.With the promotion of motor application efficiency, size reduction, however thermal power density also with
Increase.Therefore, also opposite raising is required to the cooling capacity of motor, whether motor can be by good cooling to remain normal
Operating temperature is then directly related to the heat dissipation arrangement of motor.In general, the operational design of different motors, can make stator pack,
Rotor set has motor loss, and rotor loss can be converted into the form of heat, and the heat generated can be transferred on bearing, bearing sheet
Body also generates frictional heat because of the high revolving speed of shaft, excessive frictional heat will so that Bearing Temperature and damage, cause motor
The problem of vibration is even damaged.
For motor under the design condition for allowing to operate continuously, copper wire winding temperature in stator pack is every to promote 10 DEG C, makes
Service life will drop by half.It is coated on crisp caused by the thermal stress and heat fatigue that insulated paint outside copper wire is then easily generated by high temperature
Change, cracking.
In order to avoid high temperature causes motor part life to shorten or damage, it will usually coolant flow channel is set on motor, and
Cooling fluid is imported in coolant flow channel to cool down to motor.Excellent coolant flow channel arranged mode can promote motor
Efficiency, performance and service life, but excessively complicated runner makes that the degree of difficulty of manufacture increases and cost improves instead, does not meet effect
Benefit.
Existing motor cooling passageway arrangement is only applicable to certain types of motor mostly, such as the application of cavity runner
Example is applied in large-size machine based on the more small-sized motor of cooling, and because calorific value is promoted, cooling situation is easily because of stream
Hot spot is caused in the recirculating zone that body is formed, and motor is made locally to generate the excessively high situation of temperature in this.In the bad situation of cooling condition
Under, the chance that such cavity runner generates nuclear boiling is promoted, phase transformation variation meeting generated by nuclear boiling so that motor generation gas explosion,
The phenomenon of leak, fatigue etc. causes the risk of motor application also to increase.In addition, also have the application of helical flow path, such cooling
Runner is universal to be applied in the cooling of motor, and helical flow path is the cooling layout using a flow-in hole and a flow-out hole, cold
But fluid enters helical form coolant flow channel by flow-in hole from one end of motor, then is left by flow-out hole by the motor other end cold
But runner, and the high fever on motor is taken away simultaneously, thus reach cooling effect.However, cooling fluid flows in coolant flow channel
During can absorb heat and gradually increase own temperature, when cooling fluid reach flow-out hole when, temperature has been higher than cooling stream
Body not yet enters the temperature of coolant flow channel, therefore, can not show a candle to close to the motor part cooling effect obtained of flow-out hole close
The cooling effect of the motor part of flow-in hole.The size and length of motor are excessive, aggravate helical flow path to stator before and after motor around
The even problem of group inhomogeneous cooling.
Summary of the invention
The present inventor is in view of traditional motor cooling passageway only allows cooling fluid to enter from motor one end and leads to electricity
It is insufficient with missing to improve its for the poor disadvantage of the cooling effect of the machine other end, and then creates a kind of tool dual-cooled runner
Motor housing component.
The purpose of the present invention is to provide a kind of motor housing components for having dual-cooled runner, the cooling stream of two thereon
Road allows cooling fluid to enter respectively from the both ends of casing assembly, then leaves respectively from the both ends of casing assembly, therefore casing assembly
Every one end can receive not yet with motor stator group heat source generation heat exchange and the lower cooling fluid of temperature, reach uniform cooling
Effect.
In order to achieve the above object, make it is aforementioned tool dual-cooled runner motor housing component include:
One shell, it is cylindrical, it is symmetrical and mutually indepedent and be not attached to that two are formed on the outer surface of the shell
