Abstract

The utility model belongs to the technical field of a motor, disclosing a reverse double water channels cooling structure of the motor. A housing of the motor forms a hollow cavity by a water inlet, a water outlet, an outer water housing of the motor, an inner water housing and a baffling tendon; the cooling water with a certain pressure can flow in the hollow cavity by the baffling effect of the baffling tendon so that a stator iron core can be cooled compulsively by an external surface of the motor; the water inlet and the water outlet are separately provided with one, and the water inlet is adjacent to the water outlet; the baffling tendon divides the water channel into two parallel inlet and outlet water channels so that two sides of each baffling tendon are provided with cooling water structures having opposite flowing directions. The reverse double water channels cooling structure of the motor has the advantages of accelerating the flowing speed of the cooling water, thereby effectively reducing the temperature on the surface of the motor. The temperature on the surface of the motor tends to balanced; the structure is suitable for the design requirements of different motors, thereby improving the operation property of the motor and increasing the service life of the motor.

Description

A kind of reverse pair of water channel cooling structure of motor

Technical field

The utility model belongs to the motor technology field, is a kind of reverse pair 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 our different motor.

The utility model content

At the technical problem of above-mentioned existence, the purpose of this utility model provides a kind of reverse pair of water channel cooling structure of motor, and concrete scheme is as follows:

A kind of reverse pair of water channel cooling structure of motor, it is characterized in that: the shell of motor is by water inlet, delivery port, the outer water jacket of motor, inner water sleeve and baffling muscle are formed cavity, 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 water inlet, each one of delivery port, and described water inlet, the delivery port position is adjacent, described baffling muscle is slit into two parallel advancing with the water route average mark, the water outlet route, all there is the structure of the opposite cooling water of flow direction the both sides of realizing each baffling muscle.

The utility model beneficial effect 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 gate structure schematic diagram of the present utility model;

Fig. 2 is a motor of the present utility model water route structural representation;

Fig. 3 launches schematic diagram for single cycle structure;

Fig. 4 is that two channel structures 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 are the water inlet route; 7 are the water outlet route; 8 is delivery port; 9 is water inlet.

Embodiment

Below in conjunction with drawings and Examples the utility model is described further:

As Fig. 1～shown in Figure 2, motor housing is formed cavity by water inlet 9, delivery port 8, outer water jacket 3, inner water sleeve 4 and baffling muscle 5, 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.

Fig. 3 is a cooling water loop structure commonly used now.When motor is connected with the cooling water of certain pressure, cooling water will flow into by water inlet 9 places, begin from water inlet route 6, the delivery port 8 that moves towards water outlet route 7 places in the direction of arrows flows out, longer to water outlet saliva water route from water inlet as can be seen, when motor power (output) was big, circle diameter was also bigger, there is ladder in the temperature of water-in and water-out like this, and the motor surface temperature also will be the raising of ladder.

Fig. 4 is a reverse pair of water channel cooling water loop structure described in the utility model, when motor is connected with the cooling water of certain pressure, cooling water will flow into by water inlet 9 places, water inlet route 6 is divided into two-way to begin to flow, move towards in the direction of arrows, the water at two places water outlet route, 7 places flows out through delivery port 8.As can be seen, 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.

Claims
