There is provided it is an object of the invention to overcome disadvantages mentioned above it is a kind of effective cooling and water resistance is excellentWater cooling shell of electric machine。
Technical scheme：A kind of motor housing of built-in water-cooling system, including motor stator and rotor being accommodated into casing therein, the matched drive end bearing bracket in casing one end being arranged on, is arranged on the matched rear end cap of the casing other end, the runner of Cooling Water flowing is axially provided with the casing, the motor housing of the built-in water-cooling system also includes two O-ring seals, is separately positioned in the annular groove left on the drive end bearing bracket, rear end cap.
The motor housing of above-mentioned built-in water-cooling system, wherein：The runner quantity is even number bar.
The motor housing of above-mentioned built-in water-cooling system, wherein：The casing two ends are machined with the kidney slot of runner quantity half, and every kidney slot connects two adjacent channels.
The motor housing of above-mentioned built-in water-cooling system, wherein：Sealing ring kidney slot corresponding with kidney slot on casing is provided with O-ring seal.
The motor housing of above-mentioned built-in water-cooling system, wherein：The O-ring seal material is silicon rubber.
The motor housing of above-mentioned built-in water-cooling system, wherein：The casing left end is set with the location dislocation of the kidney slot of right-hand member；There is one to be divided into two sections of blind holes that are coaxial but disconnecting in the runner, be connected with delivery port, water inlet by the water channel that comes in and goes out respectively, remaining runner is all through hole.
The present invention compared with prior art, the present invention using silicon rubber plasticity is good, good airproof performance the characteristics of, runner is effectively sealed using falope shape sealing ring, water resistance is excellent；Runner both sides are linked up using kidney slot, the location dislocation of kidney slot is set, there is one to be divided into two sections of blind holes that are coaxial but disconnecting in runner to be connected with delivery port, water inlet by the water channel that comes in and goes out, and remaining runner is through hole, along with being provided with sealing ring kidney slot corresponding with kidney slot on casing in O-ring seal, enter air stream enter runner until delivery port must be after all runners from water inlet this means cooling water, this just make cooling water walking path is most long, cooling-down effect preferably, reach the purpose of temperature with high efficiency.

Specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the motor housing specific embodiment according to built-in water-cooling system proposed by the present invention, structure, feature and its effect, describe in detail as after.
The schematic diagram of motor water cooling system of the prior art is as shown in Fig. 1, Fig. 2, it includes the drive end bearing bracket 1, the rear end cap 3 that accommodate casing 2 therein, be arranged on the two ends of casing 2 and coordinate with casing motor stator and rotor, the runner 4 of Cooling Water flowing is axially provided with the casing 2, have a disadvantage in that two ends are sealed only with drive end bearing bracket 1, rear end cap 3, sealing effectiveness is poor, easily infiltration enters motor internal, cooling water is only just directly flowed away by a runner 4 when cooling down simultaneously, and cooling effect is poor.
The motor housing of built-in water-cooling system of the invention, in prior art basis, annular groove is respectively kept with drive end bearing bracket 1, rear end cap 3, and an O-ring seal 5 good fit with groove is respectively set, connected mode can be using chimeric, gluing, preferably glue bonding, the structure of O-ring seal 5 is as shown in figure 3, be provided with concentric multiple-sealed circle kidney slot 6.Fig. 4, Fig. 5 are drive end bearing bracket of the invention 1 and the cooperation schematic diagram of O-ring seal 5, and the cooperation of rear end cap 3 and O-ring seal 5 is similarly.
Fig. 6 is casing side view of the invention, and the quantity of runner 4 is even number bar, preferably 16；The two ends of casing 2 are machined with the kidney slot 7 of the quantity half of runner 4, and preferably 8, every kidney slot connects two adjacent channels 4.The location dislocation of the kidney slot 7 of the left end of casing 2 and right-hand member is set, will runner 4 by 1~16 numbering, if the connection of kidney slot 7 1-2 of the left end of casing 2,3-4,5-6 ..., 15-16, the kidney slot 7 of right-hand member then connect 2-3,4-5,6-7 ..., 16-1；As shown in fig. 7, there is one to be divided into two sections of blind holes that are coaxial but disconnecting in the runner 4, it is connected with delivery port, water inlet by the water channel 8 that comes in and goes out respectively, remaining runner 4 is all through hole.
Principle of the invention：O-ring seal 5 can effectively fetter cooling water plus multiple-sealed circle kidney slot 6 thereon, make its circulation in runner 4, and seepage problem will not occur.Meanwhile, if that runner 4 disconnected is for No. 1 runner, then No. 1 the two of the runner water channels 8 that come in and go out are connected with extraneous delivery port, water inlet respectively, water inlet flows into kidney slot 7 by No. 1 half section of runner, No. 2 runners are entered back into, then No. 3 runners are entered by kidney slot 7, by that analogy, finally No. 1 runner is flowed back to from No. 16 runners, from No. 1 another half section of outflow of runner, that is to say, that cooling water travels through whole 16 runners, walking path is long, and its cooling performance is played completely.
The above, only it is presently preferred embodiments of the present invention, not make any formal limitation to the present invention, it is any without departing from technical solution of the present invention content, any simple modification, equivalent variations and the modification made to above example according to technical spirit of the invention, still fall within the range of technical solution of the present invention.
