Abstract
The utility model relates to a water cooling device for a motor. The water cooling device comprises a motor housing. A water inlet, a water outlet and a cooling water channel are arranged on the surface of the motor housing. The water inlet and the water outlet are respectively connected with the two ends of the cooling water channel. The water inlet and the water outlet are positioned on the same side of the motor housing. A separator plate is disposed between the water inlet and the water outlet to separate the water inlet and the water outlet. Cooling water flows through the water inlet, flows by the cooling water channel and then flows out of the water outlet. A wave-shaped cooling water channel is adopted, thereby increasing a contacting area between the cooling water and the motor housing in a limited space, and improving the cooling efficiency. The water inlet and the water outlet are positioned on the same side of the motor housing and are separated in the middle, thereby preventing the water inlet and the water outlet from mutual interference on the same side. The radial occupation dimension of a motor is reduced. The mounting of the device is quite convenient on the same side. Moreover, the cooling effect of the motor is greatly improved, the work efficiency of the motor is increased, and the housing is prevented from deformation caused by high temperature.
Description
Technical field
The utility model relates to a kind of motor water cooling radiator cooler, specifically is used for motor is dispelled the heat at the heat that running produces, and with the safe operation of assurance equipment and the normal performance of performance, belongs to technical field of motors.
Background technology
At work, often need the heat that motor produces in running be dispelled the heat, with the safe operation of assurance equipment and the normal performance of performance.That cooling device at present commonly used comprises is air-cooled, oil cooling and three kinds of modes of water-cooled.In motor application, comprehensive cooling performance and Financial cost are main with air cooling mainly.Air cooling is structurally simple, and cost is easy to maintenance; These remarkable advantages make air cooling at first obtain using and development, still, and along with the increase of capacity motor; Amount that the motor feels hot is also increasing; Need to strengthen cooling and just must strengthen ventilation quantity, thereby increase draft loss, reduce electric efficiency.
Water-cooling pattern is because the convection transfer rate of water is more than 150 times of control nature heat exchange coefficient, and rate of heat dissipation is high; It does not have pollution and the problems such as noise inflammable and that adopt forced air cooling to produce that the oil cooling mode possibly brought again simultaneously, so obtained concern more and more widely.
In prior art; The water cooling system of water-cooled machine generally is divided into two kinds of forms; A kind of is to add but device of water-air cooling in the motor outside; The motor internal heat takes the empty cooler of external water to by the inner air circulatory system, and the heat exchange of the aqueous medium in this completion and external circulating system, thereby constantly the motor heat is taken away; Another kind is directly to offer water channel in base inner, directly motor is cooled off, i.e. support formula water-cooled machine.But the entery and delivery port of general support formula water-cooled machine is at homonymy, and the centre does not separate, and cooling water channel is a linear pattern; Entery and delivery port links to each other, and may cause interfering with each other, and makes the current short circuit; Cooling water flows to from water inlet; Directly flow out, or have only a spot of water behind water channel, to flow out, directly cause the cooling effect variation of motor from delivery port from delivery port.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, thereby a kind of motor water cooling radiator cooler is provided, and this device can increase the contact area of cooling water and body in limited space, improved cooling effectiveness; And the drawback that can avoid entery and delivery port can interfere with each other at homonymy.
The technical scheme that provides according to the utility model; A kind of motor water cooling radiator cooler comprises electric machine casing; Characteristic is: the surface of said electric machine casing is provided with water inlet, delivery port and cooling water channel, and said water inlet, delivery port are connected with the two ends of cooling water channel respectively.
Said water inlet and delivery port are in the same side of electric machine casing, are provided with dividing plate in the middle of water inlet and the delivery port, and water inlet and delivery port are separated, and after cooling water got into through water inlet, the cooling water channel of flowing through flowed out from delivery port again.
Said cooling water channel was provided with around one week of electric machine casing, and it is shaped as undaform.
Compared with present technology the utility model has the following advantages:
The utility model has adopted the cooling water channel of undaform, in limited space, has increased the contact area of cooling water and body, has improved cooling effectiveness; Water inlet and delivery port are positioned at the homonymy of body, with spaced intermediate, and the drawback that can avoid entery and delivery port can interfere with each other like this at homonymy; What also reduced motor radially takies size, and very convenient when homonymy is installed; Improved the cooling effect of motor greatly, improved the operating efficiency of motor, avoided because of the high body deformation that causes of temperature.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 is the utility model cooling water channel expanded view.
Fig. 3 is the utility model 3-D view.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
Like Fig. 1～shown in Figure 2, comprise water inlet 1, delivery port 2, cooling water channel 3, electric machine casing 4.
Said water inlet 1, delivery port 2 are provided with respectively with cooling water channel 3 and are positioned at electric machine casing 4 surfaces, and said water inlet 1, delivery port 2 are connected with the two ends of cooling water channel 3 respectively; Water inlet 1 and delivery port 2 are in the same side of electric machine casing; Water inlet 1 and the delivery port 2 middle dividing plates 5 that are provided with; Water inlet 1 and delivery port 2 are separated; Cooling water flows into water channel from water inlet, need flow through through cooling water channel and take away the heat that machine operation produces in one week of electric machine casing, flows out from delivery port.
Shown in Figure 2, be the expanded view of cooling water channel 3, it is shaped as undaform, has increased the contact area of cooling water and electric machine casing 4, has improved cooling effect.
Shown in Figure 3, be the 3-D view of motor, displaying be the positional structure of cooling water channel 3 and motor, cooling water channel 3 is on electric machine casing 4 surfaces, directly casting forms, and has both guaranteed body intensity, has also guaranteed cooling effect.
During machine operation; Outside at motor; Having the device of recirculated water and the water inlet of the utility model is connected with delivery port; Cooling water is flow to by water inlet in the cooling water channel of motor outer surface, is got back in the outer cooling water circulating device of motor by the delivery port outflow motor again, so just can form boiler water circulation at the outer surface of electric machine casing.
