Description
Technical field
The present invention is related to a kind of electro-motor, especially has the electro-motor of water-cooling radiating structure.
Background technology
Due to general motor in the running, rotor within motor is excitatory with stator meeting mutual induction and produces heat, and these heats because cannot quickly leave inside motor, and can cause motor shortening in service life, so insider is in order to improve said motor problem, develop a kind of water-cooled motor.
Consult Figure 16, existing general water-cooled motor includes a motor body 30 and a cooling base 31, wherein said motor body 30 comprises a shell 303 and 306,307 and rotor 301 of two lids and a stator 302 is set on rotor 301, described shell 303 has an accommodation space 3033 and arranges described cooling base 31 in order to hold, and the two ends of described accommodation space 3033 are docked with two corresponding lid 306,307 phases respectively; And described shell 303 also has the water entering section 30312 of an outlet part 30311 described outlet part 30311 relative to, described outlet part 30311 and water entering section 30312 are respectively provided on the outside of described shell 303.
Above-mentioned cooling base 31 has an accommodation portion 312 and connects described accommodation space 3033, described accommodation is not in order to hold described stator 302 and rotor 301, article one, runner 313 along the outer circumferential side of described cooling base 31 around arranging formation, and outlet part 30311 and water entering section 30312 described in described flow passage, so when motor running produces heat, cooling base 31 can absorb the heat on stator 302 and rotor 301, through a kind of fluid (such as water, coolant) circulating in runner 313, heat exchange is carried out with the heat on cooling base 31, and then reach the purpose of heat radiation.
But, although existing water-cooled motor can this borrower's runner reach heat radiation purpose, but truly have problem to exist in actual use, namely owing to the fluid-flow rate in runner 313 is fast, make fluid retention too short in the time of cooling base 31, causing that fluid is low with the heat exchanger effectiveness of cooling base 31, radiating effect is had a greatly reduced quality.
Because inner flow passage 313 of the prior art is unidirectional smooth runner, so cooling liquid is shorter for the dead time in this runner 313 of the same race, the thermal source taken away is less, then significantly reduces heat exchanger effectiveness and the heat transfer effects of entirety, and relative integral heat sink effect is more undesirable; So prior art has the disadvantage that
1. heat exchanger effectiveness is not good;
2. radiating effect is not good.
