In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The water cooling base structural representation that Fig. 1 provides for embodiment a kind of in the present invention.
In accompanying drawing, mark is as follows:
1-sealing ring, 2-pedestal, 3-sealant, 4-stator core, 5-water channel.
Embodiment
Core of the present invention is to provide a kind of water cooling base, effectively improves the cooling effect of water cooling base; Another core of the present invention is to provide a kind of motor comprising above-mentioned water cooling base.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, the water cooling base structural representation that Fig. 1 provides for embodiment a kind of in the present invention.
In a kind of embodiment, the water cooling base of motor provided by the present invention, comprise pedestal 2, pedestal 2 suit is installed in stator core 4, the inner surface of pedestal 2 has water channel 5, without inner water sleeve in pedestal 2, the structure more of pedestal 2 is simple, material usage is less, weight saving, and manufacturing cost reduces.The outer surface of stator core 4 has sealant 3, sealant 3 has thermal conductivity, sealant 3 plays the function of inner water sleeve, cooling water in water channel 5 directly can contact with the sealant 3 of stator core 4, when water channel 5 directly contacts with stator core 4, cooling effect is better, water channel 5 is sealed in the space between pedestal 2 and stator core 4, and the heat that the stator core 4 of motor produces directly is taken away by cooling water, substantially improves the cooling effect of motor.
Above-mentioned water cooling base is only a kind of preferred version, specifically be not limited thereto, pointed adjustment can be made according to actual needs on this basis, thus obtain different execution modes, interference fit seal is passed through in pedestal 2 and stator core 4, with this, water channel 5 is sealed in the space between pedestal 2 and stator core 4, it should be noted that, by interference fit seal be one preferred embodiment, be not unique, can also by other suitable mode, the end of such as stator core 4 is fixed in pedestal 2 by welded seal, welding method fixing seal is adopted at pedestal 2 and the outer of stator core 4 faying face, fixation, sealing is better.
Another inventive concept set forth provided by the present invention is, the contact end portion of pedestal 2 and stator core 4 is provided with sealing ring 1.Pedestal 2 and stator core 4 contact two ends be provided with sealing ring 1 together respectively can enhanced leaktightness effect, the position of sealing ring 1 is unrestricted, can be arranged at the outside of contact end portion, also can be arranged at the outer ring of contact end portion, concrete installation site can be determined according to practical situations.
