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 waterway 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 larger ladder temperature difference.Affect 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 when motor electromagnetism design process in the selection heat load higher, when motor power (output) is larger, 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 affects motor mass.Therefore, we wish a kind of can be under the surface area of limited water route, the cooling water circulation 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
For the technical problem of above-mentioned existence, the invention provides a kind of many waterway cooling structures in many mouths of a river of motor.Concrete scheme is:
A kind of many waterway cooling structures in many mouths of a river of motor, the cavity that is comprised 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 by the motor outer surface stator core is forced cooling, described baffling muscle is continuous structure, described cavity is divided into many cooling water channels, described water inlet, delivery port also relative set are a plurality of, the setting alternate 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: the flowing velocity of having accelerated cooling water.Thereby effectively reduce the motor surfaces temperature, make 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 motor waterway structure schematic diagram of the present invention;
Fig. 2 is 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:
Such as Fig. 1～shown in Figure 2, the motor stator cooling water channel structure comprises that outer water jacket 3, inner water sleeve 4 and baffling muscle 5 form cavity, by the barrier effect of baffling muscle 5, cooling water is flowed in cavity, thereby by the motor outer surface stator core 1 is forced cooling.
Embodiment: be the two water channel cooling water circulation structures in two mouths of a river such as Fig. 1～Fig. 2.Motor has respectively two water inlets 6 and two delivery ports 7; Every side is 6 one delivery ports 7 of a water inlet, and corresponding opposite side is 7 one water inlets 6 of a delivery port with it, 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 respectively two place's delivery ports 7 along the direction of arrow.There is the flow of cooling water of opposite 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 the motor surfaces temperature basically identical, solved the large practical problem of temperature gradient in the motor cooling water cycle process.
For strengthening cooling effect, cooling water channel can suitably increase, and the flow direction of the cooling water of each cooling water channel is opposite with adjacent water channel, and correspondingly, water inlet and delivery port are alternately.
Claims (2)
1. the many waterway cooling structures in many mouths of a river of a motor, it is characterized in that: by water inlet, delivery port, the outer water jacket of motor, the cavity that inner water sleeve and baffling muscle form 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 by the motor outer surface stator core is forced cooling, described baffling muscle is continuous structure, described cavity is divided into many cooling water channels, the alternate setting of described cooling water channel, the flow direction of the cooling water of each described cooling water channel is opposite with adjacent cooling water channel, described water inlet, delivery port also relative set is a plurality of, the setting alternate with delivery port of each end water inlet.
2. cooling structure according to claim 1, it is characterized in that: described cooling water channel is 2, described water inlet, delivery port respectively are two.
