Description
Technical field：
The present invention relates to a kind of leakage-proof structure of motor casing water cooling runner.
Background technology：
Recirculated cooling water is the conventional cooling means of motor, by setting runner on motor casing, takes away cooling water
Inside is delivered to the heat of casing outer surface, to reach the purpose to stator cooling.Runner generally has following manner to realize：
1) the pre-buried good circulating line before casing pours；This kind of mode requires that pre-buried pipeline fusing point cannot be below case material
When, therefore have some limitations；
2) directly obtained using section bar；This kind of mode can be limited when installing in the later stage by by concrete structure shape,
Part use occasion can be only put at the outside of motor case, therefore cooling-down effect is limited.
The content of the invention：
The present invention is to provide a kind of anti-letting out of motor casing water cooling runner to solve the above-mentioned problems of the prior art
Drain structure.
The technical solution adopted in the present invention has：A kind of leakage-proof structure of motor casing water cooling runner, including inner housing and
Shell body, the outer wall of the inner housing are provided with leakage-preventing runner and radiating flow passage, and leakage-preventing runner is placed in the upper of radiating flow passage
Side, and both do not penetrate mutually, from top to bottom layering is provided with outlet, water inlet and delivery port, shell in the side wall of shell body
Body is sheathed on inner housing, and inside and outside housing is welded to each other, and shell body seals the radiating flow passage on inner housing, on shell body
Water inlet and delivery port correspond to be connected with the upper and lower ends of radiating flow passage on inner housing respectively, outlet and leakage-preventing runner
It is connected.
Further, the side wall of the inner housing is provided with positioning step portion, and the lower surface of shell body is placed in positioning step
In portion, and it is welded to each other between the lower surface of inner housing and positioning step portion.
Further, the leakage-preventing runner is toroidal.
Further, the radiating flow passage is helical form.
The present invention has the advantages that：
1) present invention is easy to manufacture, good heat dissipation effect；
2) present invention can be effectively prevented from risk of the liquid in welding seam failure through welding seam leakage to motor internal.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is partial enlarged drawing of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the present invention discloses a kind of leakage-proof structure of motor casing water cooling runner, including the He of inner housing 1
Shell body 2, is provided with leakage-preventing runner 10 and radiating flow passage 11 on the outer wall of inner housing 1, and leakage-preventing runner 10 is placed in sink flows
The top in road 11, and leakage-preventing runner 10 and radiating flow passage 11 do not penetrate mutually, from top to bottom layering is set in the side wall of shell body 2
There are outlet 20, water inlet 21 and delivery port 22, shell body 2 is sheathed on inner housing 1, and inside and outside housing is welded to each other.Shell
Body 2 seals the radiating flow passage 11 on inner housing 1, and water inlet 21 on shell body 2 and delivery port 22 correspond to respectively and inner casing
The upper and lower ends of radiating flow passage 11 are connected on body 1, and outlet 20 is connected with leakage-preventing runner 10.
Positioning step portion 13 is provided with the side wall of inner housing 1, the lower surface of shell body 2 is placed in positioning step portion 13,
And it is welded to each other between the lower surface and positioning step portion 13 of inner housing 1.Positioning step portion 13 on the one hand cause inside and outside housing it
Between position reliable, the setting in another aspect positioning step portion 13 causes the weld seam of inside and outside housing lower end be located on the outside of shell body 2,
Even if commissure cracks, in the presence of hydraulic pressure, recirculated water is not penetrated into inner housing 1 yet.
Leakage-preventing runner 10 in the present invention is toroidal, and radiating flow passage 11 is helical form.
When in use, cooling water enters radiating flow passage 11 from water inlet 21, cold to the stator in inner housing 1, rotor part
But discharged again from delivery port 22 after, radiating flow passage 11 is placed between inner housing 1 and shell body 2, is cooled down to the inner part of inner housing 1
When, and can is enough to be cooled down to the part outside shell body 2, and radiating flow passage 11 is distributed in the shape of a spiral, runner length, radiating effect
It is good.
In use, if the commissure of inside and outside housing upper end cracks, the water of radiating flow passage 11 is no longer located
In sealed environment, under hydraulic pressure effect, external environment condition can be flowed to along crackle.Because outlet 20 and radiating flow passage 11 are only each other
Vertical non-interconnected, then fluid is discharged, as shown in Fig. 2 arrow is in figure when not yet reaching bead crack by outlet 20
For fluid under pressure, by coordinating wall to infiltrate into the process of outlet 20, therefore liquid will not be caused to enter inner casing
In body 1, motor damage is avoided.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
