Abstract
The invention belongs to the technical field of motors, and discloses a multi-water gap multi-waterway cooling structure for the motor. Cooling waterways are formed on the outer surface of the motor by a cavity consisting of water inlets, water outlets, an outer water jacket of the motor, an inner water jacket and a deflection rib. Cooling water with a certain pressure flows in the cavity under the blocking function of the deflection rib, thereby forcibly cooling a stator core by the outer surface of the motor. The deflection rib has a continuous structure and divides the cavity into a plurality of cooling waterways. A plurality of water inlets and a plurality of water outlets are correspondingly formed. The water inlet and the water outlet at each end are arranged at an interval. The cooling structure has the advantages of accelerating the flowing of the cooling water, thereby effectively reducing the surface temperature of the motor, making the surface temperature of the motor tend to be equalized, achieving adaptability to the designing needs of different motors, further improving the running performance of the motor and prolonging the service life of the motor.
Description
Technical field
The invention belongs to the motor technology field, is a kind of water channel cooling structure of motor specifically.
Background technology
Existing water-cooled motor is generally single channel structure, by the water that flows a part of heat that the motor stator winding produces is taken away, this moment, water inlet, the water outlet after circulation had certain temperature difference, length according to the water route, motor water inlet along the water route behind delivery port, form bigger ladder temperature difference.Influence the radiating effect of motor, how to reduce the temperature difference of motor surfaces, strengthen the radiating effect of motor, it is the important topic that we face, special heat load is higher when selecting in the motor electromagnetism design process, motor power (output) is greatly the time, cooling water will be taken away how many heats of motor, and the temperature of reduction motor surfaces how much, will be a major issue that influences motor mass.Therefore, we wish to have a kind of can be under the surface area of limited water route, the cooling water loop structure of taking away the motor surfaces heat as much as possible makes motor surfaces be tending towards temperature equalization, adapts to the design requirement of different motor.
Summary of the invention
At the technical problem of above-mentioned existence, the invention provides a kind of many mouths of a river many water channels cooling structure of motor.Concrete scheme is:
A kind of many mouths of a river many water channels cooling structure of motor, the cavity of being made up of outer water jacket, inner water sleeve and the baffling muscle of water inlet, delivery port, motor forms cooling water channel at the motor outer surface, barrier effect by the baffling muscle, the cooling water of certain pressure is flowed in cavity, thereby stator core is forced cooling by the motor outer surface, described baffling muscle is a continuous structure, described cavity is divided into many cooling water channels, described water inlet, delivery port also relative set are a plurality of, the alternate setting with delivery port of each end water inlet;
For reaching the effect of even cooling, the alternate setting of described cooling water channel;
Preferred embodiment be: described cooling water channel is 2, and described water inlet, delivery port respectively are two.
Beneficial effect of the present invention is: quickened cooling-water flow speed.Thereby effectively reduced the motor surfaces temperature, made motor surfaces be tending towards temperature equalization, adapted to the design requirement of different motor, thus improved motor runnability, increased useful life of motor.
Description of drawings
Fig. 1 is a motor of the present invention water route structural representation;
Fig. 2 is the end view and position, the mouth of a river A-A partial sectional view of motor of the present invention;
Fig. 3 is that the two channel structures in two mouths of a river launch schematic diagram.
Wherein: 1 is stator core; 2 is the water route; 3 is outer water jacket; 4 is inner water sleeve; 5 is the baffling muscle; 6 is water inlet; 7 is delivery port.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples:
As Fig. 1～shown in Figure 2, motor stator cooling water channel structure comprises outer water jacket 3, inner water sleeve 4 and baffling muscle 5 composition cavitys, by the barrier effect of baffling muscle 5, cooling water is flowed in cavity, thereby stator core 1 is forced cooling by the motor outer surface.
Embodiment: as Fig. 1～Fig. 2 is the two water channel cooling water loop structures in two mouths of a river.Motor has two water inlets 6 and two delivery ports 7 respectively; Every side is 6 one delivery ports 7 of a water inlet, and corresponding with it opposite side is 7 one water inlets 6 of a delivery port, and is just in time opposite.Can find out in conjunction with Fig. 3: when motor was connected with the cooling water of certain pressure, cooling water flowed into hydroecium simultaneously by two place's water inlets 6, moved towards two place's delivery ports 7 respectively along the direction of arrow.All there is the opposite flow of cooling water of direction the both sides of each baffling muscle, the cooling water of water inlet is adjacent with delivery port cooling water muscle, the temperature difference at the temperature difference of the Origin And Destination of cooling water circulation and circulation middle part is less like this, make motor surfaces temperature basically identical, solved the big practical problem of temperature gradient in the motor cooling water cycle process.
For strengthening cooling effect, cooling water channel can suitably increase, and the cooling-water flow direction of each cooling water channel is opposite with adjacent water channel, and correspondingly, water inlet and delivery port are alternately.
Claims (3)
1. many mouths of a river many water channels cooling structure of a motor, it is characterized in that: the cavity of being made up of outer water jacket, inner water sleeve and the baffling muscle of water inlet, delivery port, motor forms cooling water channel at the motor outer surface, barrier effect by the baffling muscle, the cooling water of certain pressure is flowed in cavity, thereby stator core is forced cooling by the motor outer surface, described baffling muscle is a continuous structure, described cavity is divided into many cooling water channels, described water inlet, delivery port also relative set are a plurality of, the alternate setting with delivery port of each end water inlet.
