Internal water cooling motor, it comprises left end cap and the right end cap that enclosure axis connects respectively with bolt to two ends.Its improvements are: described left end cap and right end cap are double-deck disk-like shape, and radial section is the internal cavity structure, and the left end cap radial outer wall is provided with water inlet and communicates with internal cavity, and the right end cap radial outer wall is provided with the delivery port that communicates with internal cavity.Described shell is cylindrical jacket type structure, is provided with the rib spaced radial between the inner/outer tube of phase fit and becomes inner lead.Be equipped with the through hole of pairing mutually on described left end cap and right end cap and the shell mating surface.
In the said structure, it is the left end cap and the right end cap of internal cavity structure equally that the enclosure axis with internal cavity structure is tightly connected respectively to two ends, constitutes the cooling water channel of mutual UNICOM.Internal cavity in the shell is interval with rib, and the intensity that the orderly rib of arranging had both increased shell also can be improved the orderly flowability of cooling water, improves heat exchanger effectiveness.Be provided with one group of axial staggered long rib in the utility model, constitute the labyrinth type water channel, or the circumferential rib looping water channel that axially parallel is jagged at interval and dislocation is put, rib also can be made axial screw shape, constitutes spiral water channel.Water inlet on the left end cap and the delivery port on the right end cap adopt internal thread hole syndeton or flange connection, are convenient to external cooling water pipe and return pipe.
The utility model compared with prior art has following good effect:
1, built-in cooling water channel structure is simple, making is easy;
2, water-cooling structure in the motor that turns round under higher relatively ambient temperature conditions adopts, it is fast, effective to lower the temperature;
3, adopting the motor of interior water-cooling structure is all-sealed structure, and the dust in the environment does not advance motor interior, keeps the motor interior cleaning, can reduce heel and toe wear, improves the useful life of motor.
