Abstract
A liquid cooling electric motor, including a case, a fan cover and a rotor and a stator having a principal axis by the end cap for assembly, having the technical points: the said case is a jacket type structure full of cooling liquid, and a cooling liquid intake arranged at the bottom of the jacket, while a cooling liquid exit is arranged on the top of the jacket, and uses the pipe to make the cooling liquid intake and the exit communicate with the corresponding exit and the intake of the heat dissipation box arranged outwards, which has simple structure, markedly reduce the temperature rising of the motor on the basis of not changing the inner structure of the motor, thereby effectively overcoming the disadvantage, with the using characteristic and the service life affected by the temperature rising of the motor, and improving the working condition of the motor and advancing the service life of the motor.
Description
Technical field
The utility model relates to a kind of improved monopole asynchronous motor, particularly a kind of liquid cooling motor that utilizes cooling fluid self-loopa cooling to reduce temperature rise.
Background technology
At present, general farm machinery as hay cutter, feed grinder etc., adopts YC series capacitor start monopole asynchronous motor mostly.This miniature motor has energy loss in running, energy loss will cause heating, and its size that produces heat depends primarily on copper loss, also promptly depends mainly on the size of load.If the motor overload operation, supply voltage is too high or too low, stream time is long or not procedure operation in accordance with regulations, then the temperature rise of motor is all than higher.The main shaft of existing vane type nonventilated motor, the fan blade on the axle that places by its drive rotates, and makes cold air enter fan guard, casing is cooled off reduce temperature rise.As motor long-term work under the above-mentioned non-normal condition that causes temperature rise, the temperature rise of motor might surpass the permission temperature rise so, this not only can reduce the motor operating characteristic, but also wearing out of meeting acceleration motor insulation may cause motor to burn out when serious.
The utility model content
The purpose of this utility model provides a kind of liquid cooling motor, it is simple in structure, on the basis that does not change the motor interior structure, significantly reduce the temperature rise of motor, thereby overcome existing motor influences its operating characteristic and useful life because of temperature rise is too high disadvantage effectively, obviously improve the condition of work of motor and the useful life of improving motor.
The purpose of this utility model is achieved in that this device comprises that casing, fan guard reach by rotor that has main shaft and stator in the end cap assembling casing, its technical essential is: described casing is a jacket type structure, filling cooling fluid in the chuck, the chuck bottom is provided with the cooling fluid inlet, the chuck top is provided with cooling liquid outlet, and utilizes that conduit makes cooling fluid inlet, outlet exports accordingly with external heat radiation case respectively, entering the mouth is communicated with.
Because the utility model is improved on existing single-phase asynchronous electronic architecture basics, does not change the motor interior structure, only changes the structure of its casing, be easy to realize.This device changes former casing into jacket type structure, all the other parts are constant substantially, filling cooling fluid in chuck makes the cooling fluid inlet of chuck bottom and the cooling liquid outlet on chuck top simultaneously, utilizes that conduit exports accordingly with external heat radiation case respectively, entering the mouth is communicated with.Flow by the self-loopa of cooling fluid in chuck and to strengthen heat exchange, reduce the temperature rise of motor, reach the condition of work of improving motor and the purpose that improves the useful life of motor, thereby overcome existing motor influences its operating characteristic and useful life because of temperature rise is too high disadvantage effectively.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device improves on existing single-phase asynchronous electronic architecture basics, does not change the motor interior structure, only changes the structure of its casing.It comprises that the casing, the fan guard 8 that have base 9 reach by parts such as rotor that has main shaft 15 in the end cap 2 assembling casings and stators 4.Wherein the specification of base 9, fan guard 8, end cap 2, rotor 5 and stator 4, size keep former universal architecture constant substantially, and whole machine installation, occupation mode are constant.Former casing is replaced by jacket type structure, and this chuck is welded type or the cast type sealing body that is made of interior cover 6 and overcoat 3, filling cooling fluid 10 in the sealing body.Cooling fluid 10 can be liquid such as oil, water.The bottom of chuck overcoat 3 is provided with cooling fluid inlet 7, and the top of overcoat 3 is provided with cooling liquid outlet 11.Cooling fluid inlet 7 utilizes conduit to be communicated with the corresponding cooling liquid outlet of external heat radiation case (not shown), and cooling liquid outlet 11 utilizes the corresponding cooling fluid inlet of conduit and heat radiation case to be communicated with, and forms self-circulation cooling loop.The specification of this external heat radiation case, size, shape and installation site should be determined according to actual instructions for use.But cooling fluid 10 natural circulation of splendid attire in the chuck, also the available pump forced circulation should be dosed anti-icing fluid at cold district.
Claims (1)
1, a kind of liquid cooling motor, comprise that casing, fan guard reach by rotor that has main shaft and stator in the end cap assembling casing, it is characterized in that: described casing is a jacket type structure, filling cooling fluid in the chuck, the chuck bottom is provided with the cooling fluid inlet, the chuck top is provided with cooling liquid outlet, and utilizes that conduit makes cooling fluid inlet, outlet exports accordingly with external heat radiation case respectively, entering the mouth is communicated with.
