The cooling system of the utility model can substantially decrease the axial space occupied by a cooling water sleeve in a present cooling system, the temperature distribution uniformity of windings is obviously improved, and the heat radiation capability is greatly improved.
Description
technical field
The utility model relates to machine field, particularly a kind of compact high performance disc type electric machine water-cooling system.
Background technology
The water-cooling pattern that disc type electric machine adopts mostly at present is in periphery unshakable in one's determination disc cooling jacket is set, cooling jacket is open circles plate-like or spiral water jacket is set, as shown in the patent that publication number is CN 102790473 A, its operation principle is, in motor case periphery, cooling jacket is set, in cooling jacket, pass into cooling water, mobile generation heat loss through convection by cooling water in water jacket, heat in motor winding and iron core is taken away from casing, first the defect of this cooling structure is disc cooling jacket axial occupation space greatly, make disc type electric machine axial dimension short, the advantage that is flat is weakened, this tradition water-cooling system can cause winding temperature skewness, and especially winding overhang becomes hottest point conventionally, finally, be difficult to guarantee good contact between cooling jacket and stator core, radiating effect reduces.
Utility model content
The purpose of this utility model is to overcome existing above-mentioned deficiency in prior art, a kind of occupied axial space of cooling jacket that significantly reduces is provided, obviously improves the uniformity that winding temperature distributes, the compact high performance disc type electric machine water-cooling system that greatly improves heat-sinking capability.
In order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of compact high performance disc type electric machine water-cooling system, comprise motor stator, described motor stator comprises the stator core of annular, described stator core surface is radially evenly distributed with some grooves, between adjacent two grooves, it is protruding stator iron core tooth portion, described in each, stator iron core tooth portion is all provided with stator winding coil, is provided with S type cooling water pipe in the groove of described stator core, described S type cooling water pipe and the laminating of described stator winding coil.
Also comprise the second motor stator that another is identical with the motor stator structure of described annular, in the groove of the stator core of the second motor stator, be also provided with S type cooling water pipe, described motor stator and the symmetrical laminating of described the second motor stator.
Described motor stator and described second motor stator of symmetrical laminating are installed in same motor casing, and delivery port and the water inlet of the S type cooling water pipe on described motor stator and described the second motor stator stretch out in respectively described motor casing.
compared with prior art, the beneficial effects of the utility model:
During the utility model work, by S type cooling water pipe in the equally distributed groove of motor stator core radial surface, directly the part heat producing in the heat producing in winding and stator core is directly taken away by the cooling water in water pipe, significantly reduce the occupied axial space of cooling jacket, obviously improve uniformity, S type cooling water pipe and the laminating of described stator winding coil that winding temperature distributes, compact conformation and greatly improve heat-sinking capability, thus the torque density of motor further improved.By the end size for connection of cooling water pipe is rationally set, can realize directly cooling to end winding, greatly reduce the local overheating problem causing because temperature distributing disproportionation is even.
