Abstract
The utility model discloses a kind of motor evaporation cooling constructions, heat exchanger including outside motor is arranged in, the heat exchanger connects return pipe, the top of stator and rotor inside motor is arranged in return pipe, it is provided with ventilation shaft connection heat exchanger at the top of the motor, is provided with blower in ventilation shaft.The utility model has the advantages that structure is simple, by the way that cooling medium liquid is recycled, the temperature that motor uses is substantially reduced.
Description
Technical field
The utility model relates to motor cooling field, especially a kind of motor evaporation cooling construction.
Background technique
Motor is often cooling with air at present, and water cooling is hydrogen-cooled, and nitrogen is cooling etc..Evaporation cooling has been applied to the hydraulic turbine or vapour
On turbine, due to price and structure, middle and small motor seldom sees evaporation cooling construction.Evaporation on water wheel motor is cold
But also be only applied on motor stator, and the cooling of rotor still leans on air cooling.This patent is to answer evaporation cooling construction
For middle and small motor, and at the same time being cooled down to rotor, and simplify cooling as a result, being carried out using cooling tower secondary
It is cooling, it is easy to maintain using reliable.Refrigerant of the motor when shutting down preservation be kept separately in favor of maintenance, has been reduced
Leakage.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of motor evaporation cooling construction.
The purpose of this utility model is achieved through the following technical solutions: a kind of motor evaporation cooling construction, including setting
In the heat exchanger of outside motor, the heat exchanger connects return pipe, and return pipe is arranged in the stator inside motor and turns
The top of son is provided with ventilation shaft connection heat exchanger at the top of the motor, is provided with blower in ventilation shaft.
Further, weeper is provided on the return pipe.
Further, thermometer and pressure gauge are additionally provided with inside the motor.
Further, the bottom of the motor is provided with holding vessel.
Further, the cooling water intake of the heat exchanger passes through water pipe with water outlet and connects cooling tower.
The utility model has the advantage that the utility model has the advantages of simple structure, and cooling medium liquid is instilled electricity by return pipe
The heat gasification that machine absorbed inside rotor and stator generate, the refrigerant after gasification are cold by carrying out in blower delivery heat exchanger
But, it is recycled, the temperature of motor can be effectively reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- stator, 2- heat exchanger, 3- return pipe, 4- blower, 5- rotor, 6- water pipe, 7- cooling tower, 8- storage
Tank, 9- thermometer, 10- pressure gauge.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As shown in Figure 1, a kind of motor evaporation cooling construction, the heat exchanger 2 including outside motor is arranged in, the heat
Exchanger 2 connects return pipe 3, and the top of stator 1 and rotor 5 inside motor, the top of the motor is arranged in return pipe 3
It is provided with ventilation shaft connection heat exchanger 2, is provided with blower 4 in ventilation shaft.
Further, weeper is provided on the return pipe 3.
Further, thermometer 9 and pressure gauge 10 are additionally provided with inside the motor.
Further, the bottom of the motor is provided with holding vessel 8.
Further, the cooling water intake of the heat exchanger 2 and water outlet pass through the connection cooling tower 7 of water pipe 6.
The course of work of the utility model is as follows: when motor operation, dripping refrigerant from the reflux loop 3 on motor top
The heat that liquid, liquid absorption rotor 5 and stator 1 generate becomes gas, accelerates gas to enter heat exchanger by blower 4
2, empty water heat exchange is carried out in heat exchanger 2, is become liquid after gas coolant cooling, is entered back into return pipe 3, so recycles
The thermal temperature that cold water in heat exchanger 2 absorbs motor refrigerant increases, and the water after heating flows back into cooling tower by water pipe 6
In 7, cool down in cooling tower 7, water after cooling supplies heat exchanger 2 further through water pipe 6 and uses, and so recycles.Work as motor
It shuts down in use, refrigerant gasification in part increases motor internal pressure, and leakage increases in the case where to prevent motor internal cause room temperature high
Add, therefore in rigid shut down, continue to run blower 4, heat exchanger 2 and cooling tower 7, is converted to liquid for refrigerant is as much as possible,
And it flows into the holding vessel 8 of lower part, and with valve that tank is closed.
The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model
System.Anyone skilled in the art, in the case where not departing from technical solutions of the utility model ambit, all using above-mentioned
The technology contents make many possible changes and modifications to technical solutions of the utility model, or be revised as equivalent variations etc.
Imitate embodiment.Therefore, all contents without departing from technical solutions of the utility model, the technology according to the utility model is to the above reality
Any change modification, equivalent variations and modification that example is made are applied, the protection scope of the technical program is belonged to.
