Specific implementation mode
Below in conjunction with the accompanying drawings, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
It describes in detail bright.
A kind of radiator structure of stator winding, including shell 1 and motor shaft 2, it is coaxially arranged in shell 1 to have stator 3 and turn
Son 4 is arranged with stator winding 32 in the line embedding groove 31 of the stator 3, is located at the stator winding 32 in line embedding groove 31 by insulated paint
It is closely cementing to be integrated, make to form the first ventilation hole axially through stator 3 between 31 inner wall of stator winding 32 and line embedding groove
33, it is additionally provided with fan 5 on the motor shaft 2 in shell 1.To ensure the winding installation of stator winding 32, the slot of line embedding groove 31
Chamber area of section is typically larger than the area of section of stator winding 32, and it is one that the stator winding 32 in line embedding groove 31 is closely cementing
After body, while promoting the compactness of 31 inner stator winding 32 of line embedding groove, the vallecular cavity for also making line embedding groove 31 vacant is passed through
The both ends of logical stator 3, to form the first ventilation hole 33 that gas supply stream passes through, to the thermal diffusivity of upgrading slot inner stator winding 32
Energy.When in use, the work of fan 5 will be so that form axial ventilation, gas can be by the first ventilation hole 33 to being located inside motor
Stator winding 32 in line embedding groove 31 carries out cooling heat, to ensure that it is balanced that the temperature of motor various places inside rises, avoid stator around
Loss caused by group local temperature rise is excessively high.
Preferably, the rotor 4 is equipped with the second ventilation hole 41 through rotor core, the first and second ventilation hole 33,41
Parallel arrangement.Fan 5 just can simultaneously radiate to stator 3 and rotor 4 in this way, also so that can form airflow circulating inside motor
Circuit is further ensured that in motor the uniformity of Wen Sheng everywhere.
A method of the radiator structure for making stator winding is adopted after in the stator winding 32, installation is complete
Line embedding groove 31 is passed through with pore-forming stick 6, after dipping lacquer, drying, pore-forming stick 6 is pulled out and forms the first ventilation hole 33.Pore-forming stick 6 will in this way
Squeezing stator winding 32 makes it infiltrate insulated paint in the case of close arrangement and the posture is kept to be dried.It is pulled out after drying
Pore-forming stick 6, due to the gluing effect of insulated paint, stator winding 32 will maintain the posture of close arrangement so that be obtained at former pore-forming stick 6
To form the first ventilation hole 33.It is simple and convenient, it is easy to process.
Preferably, the area of section of the pore-forming stick 6 is less than the 30% of line embedding groove vallecular cavity area of section, and pore-forming stick 6 is cut
Face area is the area of section of the first ventilation hole 33, that is to say, that the area of section of the first ventilation hole 33 is less than line embedding groove vallecular cavity
The 30% of area of section.For ease of the winding of stator winding 32, the area of section of stator winding 32 is usually the slot of line embedding groove 31
The 70% of chamber area of section, not only can guarantee the reliable installation of stator winding 32 in this way, but also can make full use of the slot of line embedding groove 31
Chamber chamber arranges the first ventilation hole 33, promotes the heat dissipation effect of stator winding 32.
Preferably, the pore-forming stick 6 is teflon rod.Polytetrafluoroethylene (PTFE) is resistant to the corrosion and its baking of insulated paint
Dry temperature, and its surface energy is low, will not lead to lacquer painting with insulated paint friction when being extracted out of line embedding groove 31 as pore-forming stick 6
It wears or falls off.
