The utility model discloses increased the heat radiating area who locates the cooling aluminum pipe in the cooling bath, the heat that makes the motor during operation produce can carry out the heat exchange with the cooling aluminum pipe rapidly reasonablely high -efficient to arrange under the condition of position at the reasonable cooling aluminum pipe of arranging, improved the heat loss rate in electric machine cooling groove.
Description
Technical field:
This utility model relates to the cooling structure of medium-sized high pressure asynchronous machine, is specifically related to a kind of have the medium-sized of Novel cooling tank
High-voltage asynchronous motor.
Background technology:
Along with Chinese society industry, expanding economy and major transformation, before medium-sized high pressure asynchronous machine has a wide range of applications
Scape, it is as the driving equipment of various universal machines, such as compressor, water pump, disintegrating machine and stock-removing machine etc., metallurgical,
As prime mover in the various industrial and mining establishment such as oil, mine, chemical industry, power station, or as driven blower, coal pulverizer, roll
Steel machine, hoist engine, belt feeder are applied.In the application that engineering is actual, the temperature of each parts of motor can be divided intuitively
Separating out the running status of motor, motor overload operation, leading phase operation etc. all can cause motor local pyrexia, to the cooling of motor
System brings bigger burden.The temperature rise of motor not only determines the safety that motor runs, and for the use longevity of motor
Life, efficiency all have a great impact.Motor works the most at high operating temperatures, and the structural member that can cause motor internal is serious
Deformation, motor safety can be run and cause threat greatly, will also result in some economic losses simultaneously by this.How to improve motor
Cooling effectiveness, make faster and better the cooling down of motor be particularly important.And cooling bath is as cooling important in motor
Link, the process cooled down for whole motor plays vital effect.In general, in medium-sized high pressure asynchronous machine
Using the cooling aluminum pipe important component part as cooler of φ=25mm, due to limited by thermocontact area, air is by cold
But the air gap of aluminum pipe is not enough, have impact on the exchange rate of air inside and outside motor, makes exchange rate reduce, thus affect
The cooldown rate of electromotor cooling system.
Summary of the invention:
This utility model is for overcoming the deficiencies in the prior art, it is provided that a kind of asynchronous electricity of medium-sized high pressure with Novel cooling tank
Machine, increases the area of dissipation of the cooling aluminum pipe being located in cooling bath, the heat energy produced when making motor work the most efficiently
Enough rapid and cooling aluminum pipe carries out heat exchange, thus in the case of reasonable arrangement cooling aluminum pipe arrangement position, improves motor
The rate of heat dissipation of cooling bath.
The medium-sized high pressure asynchronous machine with Novel cooling tank of the present utility model, including the radiating tube being located in cooling bath, adopts
Technical scheme be: described radiating tube for cooling aluminum pipe, if the outer surface of described cooling aluminum pipe has been uniformly distributed circumferentially
A dry fin, and described cooling aluminum pipe is the most serpentine-like is arranged in cooling bath.
As further improvement of the utility model, the cross section of described fin is cellular, it is possible to decrease making of cooling aluminum pipe
With cost, simultaneously facilitate the ventilation and heat of cooling aluminum pipe.
As further improvement of the utility model, the distance between the bottom of adjacent two fin is 3mm, can be easy to fluid
Quickly through.
As further improvement of the utility model, the thickness of described fin is 1-3mm, a length of 10-14mm, can be
On the premise of guaranteeing radiating effect, save material cost.
As further improvement of the utility model, the thickness of described fin is 2mm, a length of 12mm, under this size
Fin radiating effect is optimal.
As further improvement of the utility model, the cross section of described fin can be S-shaped, can increase fin further
With the contact area of fluid, simultaneously facilitate fluid radial through fin.
As further improvement of the utility model, at the air intake vent of described cooling bath and air outlet, it is respectively equipped with turbofan,
Can further improve the cooling effectiveness of cooling bath.
The beneficial effects of the utility model are: cooling bath of the present utility model uses the cooling aluminum pipe of honeycomb transformation formula, so
Increase the contact area of air, increase area of dissipation, make to be run, by motor, the heat produced simultaneously and pass through cooling bath
Gap quickly to external diffusion, and then increase the flow of hot-air, make radiating efficiency be greatly improved.For reducing aluminum further
The use cost of tube material, heat sink design is become cross section to be cellular by this utility model, can be greatly reduced the material of cooling aluminum pipe
Material cost, can be easy to cool down the ventilation and heat of aluminum pipe simultaneously.On this basis, cooling aluminum pipe is arranged to snakelike structure,
Its area of dissipation, and then the radiating efficiency of increase motor cooling bath can be increased further, simultaneously at the air intake vent of cooling bath, go out
Adding vortex flow fan at air port, vortex flow fan can increase to heat radiation aluminum pipe air-supply again while gathering all directions hot-air
Add air velocity, improve the radiating efficiency of cooling bath, the service life of motor can be greatly improved through such transformation.

Detailed description of the invention:
With reference to Fig. 3 to Fig. 5, this has the medium-sized high pressure asynchronous machine of Novel cooling tank, including the heat radiation being located in cooling bath
Pipe, described radiating tube is cooling aluminum pipe 1, and the outer surface of described cooling aluminum pipe 1 has been uniformly distributed circumferentially several fin
2, the distance between the bottom of adjacent two fin is 3mm, and the cross section of described fin 2 is cellular, its cross section
Shape can be S-shaped, its thickness is 1-3mm, a length of 10-14mm, and thickness is preferably 2mm, length is preferably 12mm,
With reference to Fig. 6, described cooling aluminum pipe 1 is the most serpentine-like to be arranged in cooling bath.The air intake vent of described cooling bath and
Turbofan it is respectively equipped with at air outlet.
Cooling aluminum pipe 1 is installed in the cooling bath of motor, is carried by this utility model on the premise of not increasing hot-air ventilation
The high cooling air contact area with cooling aluminum pipe 1, and then add the area of dissipation of each cooling aluminum pipe 1, the most right
Carry out honeycomb fashion transformation in fin 2 and be equivalent to decrease the quantity of the cooling aluminum pipe 1 being arranged in cooling bath, so cold
But decrease the quantity of cooling aluminum pipe 1 on the premise of effect is the same, thus reach to reduce the purpose of cost.
