Abstract
The utility model provides a motor with watter cooling, establish the cavity in it, establish to open cylindrical casing at both ends, is equipped with stator and rotor in the casing cavity, the rotor center is located to the motor shaft, the casing both ends are equipped with the end cover respectively, its characterized in that casing is established to the individual layer casing, and sets up the spiral pore in individual layer casing wall. Change traditional double shell water -cooled motor into single casing, not only reduced the casing quality of motor, avoid the sealed problem that adopts two casings to appear moreover. Simultaneously, use the cross -section as circular shape spiral pore, reduced the flow resistance of coolant liquid in the pore, improve cooling efficiency greatly, guarantee that the motor can normal operating.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of motor with watter cooling, belongs to Electromechanical Design manufacturing technology field.
Background technology
Along with the development of new forms of energy science and technology, electric automobile starts the most universal.Its driving motor of currently used electric automobile is generally mounted to headstock, owing to installing space is little, operating temperature is high, the outdoor temperature difference big and frequent vibration etc. affects, makes driving motor need bigger overload capacity and power density.Once improving and drive motor overload ability and power density also certainly will can increase the caloric value driving motor, common radiator fan cannot meet radiating requirements, can only use water-cooling.Existing water-cooling drives motor to use the structure of inside and outside double Shell, and processes the helicla flute around motor on interlayer inwall, takes away heat by current along helicla flute rotary motion.Easily there is leakage because of sealing or problem of aging in this double-decker, and causes burn-down of electric motor.Meanwhile, the spiral trough body structure using cross section to be rectangle also can increase resistance to water-flow, thus reduces water-cooled efficiency.It addition, double-shell structure also add volume and the weight of motor, make manufacturing cost too high.It is therefore desirable to prior art is improved.
Summary of the invention
Driving motor to use double-layer shell structure for solving existing automobile-used water-cooled, cause sealing and the problem such as cooling effect is poor, the utility model provides a kind of motor with watter cooling.
The utility model is completed by following technical proposal: a kind of motor with watter cooling, including setting cavity in it, two ends are set to uncovered cylindrical housings, stator and rotor it is provided with in housing hollow, motor shaft is located at rotor center, housing is respectively arranged at two ends with end cap, it is characterized in that housing is set to single hull, and foraminous spiral tract is set in single hull wall, this foraminous spiral tract cross section is set to circle, with will pass through single hull arrange solve sealing difference problem, then by cross section be circle foraminous spiral tract guarantee cooling effect.
Described foraminous spiral tract arranges from left to right along housing wall or right-to-left is arranged, and intensive is covered with in whole housing wall, thus ensures the integral heat sink ability of motor.
Described housing is provided with the entery and delivery port connected into and out of end respectively with foraminous spiral tract, entery and delivery port is connected with inlet tube and outlet tube respectively, inlet tube and outlet tube is connected with outside cooling pond, in order to complete the cooling of whole housing, heat radiation by inlet tube and outlet tube foraminous spiral tract water filling in housing wall.
The utility model has following advantages and effect: uses such scheme, changes traditional double Shell water-cooled motor into mono-hull, not only reduces the housing quality of motor, and avoids the sealing problem using Double-casing to occur.Meanwhile, using cross section is circular foraminous spiral tract, reduces coolant flow resistance in duct, is greatly improved cooling effectiveness, it is ensured that motor can be properly functioning.An actually preferable water-cooled motor.
