Abstract
The utility model discloses a water-cooling casing and a motor. The water-cooling casing comprises a water-cooling inner wall, a water-cooling outer wall and a sidewall which surround to form a water-cooling cavity, and a water diversion separator plate arranged in the water-cooling cavity for dividing the water-cooling cavity into a forward water channel and a reverse water channel which are communicated with each other through a water inlet end; wherein after a cooling fluid is introduced, the cooling fluid is divided into two portions to flow in the forward water channel and the reverse water channel respectively; the two water channels are separated through the water diversion separator plate, and the cooling fluid has opposite flow directions in the water channels, thus while the cooling fluid absorbs the heat radiated by a motor, heat exchange also occurs between the low-temperature cooling fluid and the high-temperature cooling fluid through the water diversion separator plate, thereby reducing a temperature gradient of the cooling fluid in the water-cooling cavity during the process of flowing, and enabling the temperature of a surface of the motor to become balanced. The utility model also provides the motor in which the above water-cooling casing is used, so as to enable the temperatures of portions of the motor to become consistent.
Description
Technical field
The utility model relates to technical field of motors, more particularly, relates to a kind of water-cooled casing, also relates to a kind of motor.
Background technology
Motor is when carrying out power conversion, always some loss changes heat into, if untimely this part dissipation of heat is gone out, can cause the temperature of motor to raise, and then cause degradation ill effect under the motor electricity function index, can cause the damage of motor internal circuit when serious.
Disc type electric machine is called again dish formula motor, is a kind of motor of thinner thickness, has wide practical use at special dimensions such as wind power generations.But, be subjected to the less restriction of disc type electric machine axial dimension, on disc type electric machine, usually can only adopt axial single waterway cooling structure.As shown in Figure 1, be provided with interior water-cooling wall 02 and outer water-cooling wall 03 at the casing 01 of disc type electric machine, the two has surrounded the waterway of disc type electric machine, is respectively arranged with outside cooling water inlet 04 and coolant outlet 05 on the water-cooling wall 03.When motor moves, utilize external pressure that cooling fluid is pressed into the waterway from cooling water inlet 04, cooling fluid contacts with interior water-cooling wall 02 and heat exchange occurs, and discharges from coolant outlet 05 at last.
In above-mentioned motor, the cooling fluid that temperature is lower enters the waterway of motor from cooling water inlet 04, and the higher cooling fluid of temperature is discharged from coolant outlet 05, and the temperature of cooling fluid raises gradually with its flowing in waterway, forms certain temperature gradient.Can expect, because the heating of motor is homogeneous comparatively, and cooling water in the waterway of motor by the time temperature raise gradually, this just causes motor to be lower than temperature at coolant outlet 05 place at the temperature place of cooling water inlet 04, and then causes the unbalanced problem of motor surface temperature.
By the above, how existing motor is improved, to reduce cooling fluid temperature gradient in the flow process in waterway, solve the unbalanced problem of motor surface temperature, become the technical problem that those skilled in the art need solution badly.
The utility model content
In view of this, the utility model provides a kind of water-cooled casing and a kind of motor, to realize reducing cooling fluid temperature gradient in the flow process in waterway, solves the unbalanced problem of motor surface temperature.
For achieving the above object, the utility model provides following technical scheme:
A kind of water-cooled casing, the water-cooled casing comprises water-cooled inwall, bailey wall and the sidewall that surrounds waterway, be provided with water inlet and the first delivery port on the bailey wall, also comprise waterway being divided into the watershed partition of the forward water channel that interconnects by water inlet end and reverse water channel and being arranged on the second delivery port on the bailey wall;
Water inlet is arranged on the connection end of forward water channel and reverse water channel, and the first delivery port is arranged on the water side of forward water channel, and the second delivery port is arranged on the water side of reverse water channel.
Preferably, in above-mentioned water-cooled casing, be provided with buttress shape kink on the watershed partition, be provided with auxiliary watershed partition in the buttress type kink.
Water-cooled casing provided by the utility model comprises water-cooled inwall, bailey wall and the sidewall that surrounds waterway, is provided with water inlet, the first delivery port and the second delivery port at bailey wall; The watershed partition that is arranged in the waterway is divided into waterway in forward water channel and the reverse water channel that interconnects by water inlet end; Water inlet is arranged on the connection end of forward water channel and reverse water channel, and the first delivery port is arranged on the water side of forward water channel, and the second delivery port is arranged on the water side of reverse water channel.
After passing into cooling fluid to water-cooled casing provided by the utility model, cooling fluid is divided into two strands, flows in forward water channel and reverse water channel respectively.Because two water channels only are separated by with watershed partition, coolant flow direction in water channel is opposite simultaneously, therefore cooling fluid is when absorbing motor institute distribute heat, also can be by watershed partition generation heat exchange between cryogenic liquid and high temperature coolant, thereby reduced cooling fluid temperature gradient in the flow process in waterway, made the temperature on motor surface be tending towards balanced.
The utility model also provides a kind of motor, in this motor, has used above-mentioned water-cooled casing, thereby the temperature between the motor each several part is reached unanimity.
