Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Purport of the present utility model is to provide a kind of new water-jacket typ water-cooled machine, to solve the cooling fluid problem that the diverse location temperature rise differs greatly in water jacket in the existing water-jacket typ water-cooled machine water jacket.
Referring to Fig. 1, Fig. 2, water-jacket typ water-cooled machine of the present utility model and conventional water-jacket typ water-cooled machine similar, by framework 1 and be installed in stator core 2 in the framework 1 and rotor structures such as (meanings not shown in the figures) constitutes, in order to solve heat dissipation problem, motor frame 1 circumference offers the water jacket 3 of being close to and centering on stator core 2, feed the cooling fluid of circulation in the water jacket 3, so that motor is cooled off.
Of the present utility modelly in water jacket 3, be provided with two cooling water channels, article two, cooling water channel has 4 openings, be respectively opening 41, opening 42, opening 51 and opening 52,4 openings are arranged on motor same end vertically, and the pipeline that can be convenient to the outer water-cooled circulation of motor so as shown in Figure 1 connects.Owing to be difficult to find out how cooling water channel is provided with among Fig. 1, Fig. 2, therefore water jacket 3 is launched, Fig. 3 cuts the water jacket among Fig. 23 open along opening 41 and opening 42 places, tile on paper in the inboard of water jacket 3 being close to stator core 2, Fig. 3 is that (opening of cooling water channel should be in upper edge in Fig. 3 for the axial direction of motor along the paper vertical direction, but for the ease of showing and marking, move downwards, this is not to be wrong).
As can be seen from Figure 3, cooling water channel 4 and cooling water channel 5 all along motor shaft to reciprocal setting, and then can be around 2 one weeks of stator core, mode is that two cooling water channels are to adopt the water-stop sheet 31 that is arranged in the water jacket 3 to be separated preferably, for those skilled in the art how water-stop sheet being set knows, be not repeated at this, like this, the water-stop sheet 31 of only being separated by between the adjacent axial water channel of cooling water channel 4 and cooling water channel 5 carries out heat exchange with the cooling fluid that is very beneficial in two cooling water channels.
We distinguish two cooling water channels around the flow direction of stator core 2 circumference and the relation of rotor rotation direction with cooling fluid in two cooling water channels, we are called first cooling water channel with the flow direction and the rotor rotation direction cooling water channel in the same way of cooling fluid around stator core 2 circumference; Cooling fluid around the flow direction of stator core 2 circumference and the cooling water channel of rotor rotation direction reversed, is called second cooling water channel.Suppose that the direction from Fig. 2 sees over, rotor rotates counterclockwise, and cooling water channel 4 is first cooling water channel so, and cooling water channel 5 is second cooling water channel.The benefit of Qu Fening is like this, which no matter see over from the axial end of motor, no matter cooling fluid is to flow or flow around stator core 2 circumference in the counterclockwise direction around stator core 2 circumference along clockwise direction in this cooling water channel, the relation of the rotation direction of itself and rotor is all determined.
Thus, cooling fluid will be opposite around the flow direction of stator core 2 circumference in two cooling water channels, the purpose of doing like this is when avoiding adopting single cooling water channel, after cooling fluid enters cooling water channel from the water inlet of cooling water channel, owing to carry out heat exchange with stator core 2, the temperature of cooling fluid can raise gradually, when power of motor is big, the water temperature difference of cooling water channel water inlet and delivery port can be very big, can cause the temperature rise of motor diverse location to have a long way to go like this, the temperature rise difference of motor diverse location is crossed the normal operation that conference has a strong impact on motor.
Adopt two cooling water channels and feed, make and carry out heat exchange between the cooling fluid in two cooling water channels, can make the temperature rise of motor diverse location keep consistent as much as possible along the opposite cooling fluid of stator core 2 circumference flow directions.Optimum set-up mode is, the water inlet of first cooling water channel is adjacent with the delivery port of second cooling water channel, and the delivery port of first cooling water channel is adjacent with the inlet port of second cooling water channel, promptly is the above-mentioned set-up mode that adopts in the present embodiment.Certainly, those skilled in the art should know, the position is set can selects of the water inlet of cooling water channel and delivery port according to actual conditions, and the set-up mode of present embodiment is not to restriction of the present utility model.
Again referring to Fig. 1, Fig. 2, in order further to strengthen radiation effect of motor, the outside of motor frame 1 inner water sleeve 3 also is provided with the air duct 6 around water jacket 3, with wind path circulation in motor frame 1, forming, cooling fluid in the water jacket 3 is when cooling off motor, and also the air to the wind path circulation cools off.Can some auxiliary heat dissipation muscle 61 radially be set along motor in the air duct 6 again, can further increase the contact area of the air of circulation in air duct 6 like this, strengthen radiating effect.
