Fig. 2 is the side view of stator of the present invention.
Wherein, the corresponding title of appended drawing reference are as follows:
10- groove, 11- fin, 100- stator.
Specific embodiment
The invention will be further described with embodiment for explanation with reference to the accompanying drawing, and mode of the invention includes but not only limits
In following embodiment.
The purpose of the present embodiment is to provide for a kind of motor that radiating efficiency is high, which includes shell and stator 100,
Chamber is defined in shell, shell is equipped with the inlet and outlet be connected with chamber.Stator 100 is located in chamber, outside stator 100
Cooling duct is defined between wall surface and the inner wall of shell, inlet and outlet is connected with cooling duct respectively.Heat exchanger channels
Be located between shell and stator 100, and cooperatively forming by shell and stator 100, cooling medium by hull outside into
Mouth enters cooling duct, after carrying out heat exchange with stator, then from outlet outflow cooling duct, so as to reach cooling stator
100 purpose.The motor of this structure can allow cooling medium directly to cool down stator 100, not need to increase cooling path, cooling effect
Rate is high, while but also the structure of motor is more compact, weight is lighter.
As depicted in figs. 1 and 2, stator 100 is formed as column, and the inner wall of the outside wall surface fitting shell of stator 100 is fixed
The outside wall surface of son 100 is equipped with groove 10, and the inner wall cooperation of groove 10 and shell limits cooling duct.That is 100 He of stator
Shell is respectively formed as column structure, and stator 100 is located in shell, and the inner wall of the outside wall surface fitting shell of stator 100.
The outside wall surface of stator 100 is equipped with groove 10, and the inner wall cooperation of groove 10 and shell limits cooling duct, inlet and outlet
It is respectively provided on shell and is connected with groove 10.
As a result, by opening up groove 10 in the outside wall surface of stator 100 and being cooperatively formed with the inner wall of shell cooling logical
Road, the cooling medium entered from the import of shell, which is directly contacted with stator 100, carries out heat exchange, reduces hot transmitting as much as possible
Path improves radiating efficiency.In addition, the stator 100 of the structure not only makes itself and shell without in addition adding heat exchanger channels
Fit structure is more compact, and alleviates weight, reduces costs.
Wherein, the specific structure of groove 10 can also be adjusted rationally according to specific needs, optionally, according to the present invention
One embodiment, the outside wall surface of stator 100 is equipped with the fin 11 of multiple arrangements axially extending and circumferentially spaced along its,
Groove 10 is equipped between the fin 11 that any two are disposed adjacent, each groove 10 is respectively along the circumferentially extending of stator 100.It is i.e. fixed
The outside wall surface of son 100 is not smooth plane, be equipped in its outside wall surface it is multiple along the axially extending of stator 100 and in the circumferential
It is spaced apart the fin 11 of distribution, usual fin 11 is three, is equipped with groove 10 between any two fin 11, each groove 10 divides
Be not formed as the arc groove of one section of circumferentially extending along stator 100.One-way conduction forms cooling duct between multiple grooves 10, i.e.,
One of groove 10 is connected with import, another groove 10 and outlet are connected, from import enter the cooling medium of groove 10 from
One end of cooling duct enters, and flows out after heat exchange from the other end.
Specifically, on the inner wall of shell position corresponding with fin 11 be equipped with vacancy, two neighboring groove 10 it
Between pass through notch be connected.It should be noted that between the two neighboring groove 10 being spaced apart by fin 11 due to fin 11 every
It is disconnected to be connected directly, vacancy can be arranged by the position cooperated on shell with fin 11, which can be by adjacent two
A groove 10 is connected, so that conducting between multiple grooves 10 be made to form complete cooling duct.The groove 10 of the structure as a result,
The heat exchange area of heat transferring medium Yu stator 100 can be improved to a certain extent, to improve heat exchange efficiency.
In addition, the motor of the present embodiment can be also arranged as follows:
As shown in Fig. 2, the outside wall surface of stator 100 is equipped with the convex of multiple arrangements axially extending and circumferentially spaced along its
Rib 11, is equipped with groove 10 between the fin 11 that any two are disposed adjacent, groove 10 be formed as along stator 100 circumferentially extending and
Along the axial S-shaped groove body fluctuated up and down of the stator 100.Each groove 10 is cooling logical with the positional relationship of fin 11 and formation
The structure in road is similar with aforementioned schemes, the difference is that, the groove 10 of the embodiment of the present invention is not only along the outer of stator 100
Peripheral wall encompasses arc groove, and also forms the structure fluctuated up and down while around the outside wall surface of stator 100, it is possible thereby to
The heat exchange area of heat transferring medium Yu stator 100 is further increased, to further increase the integral heat sink efficiency of motor.S-shaped slot
The upper surface of at least one wave crest adjacent stator 100 of body is arranged and under at least one trough adjacent stator 100 of S-shaped groove body
End face setting.Preferably, S-shaped groove body is symmetrical arranged relative to the eccentric axial of stator 100.
As shown in Fig. 2, the upper surface of the upper end adjacent stator 100 for the S-shaped structure that the fluctuation of about 10 groove body is formed, lower end are adjacent
The lower end surface of nearly stator 100, that is to say, that groove body 10 is not only circumferentially upper around entire stator 100, but also also cloth in the axial direction
Full entire stator 100.The groove body 10 of the structure not only can farthest improve the heat exchange area with stator 100 as a result, mention
High cooling efficiency, and 10 convenient formation of groove body of centrosymmetric structure, can reduce preparation cost to a certain extent.
The both ends of groove 10 can be connected, and can also be not turned on, in certain specific embodiments of the invention, import with
One end of groove 10 is connected, and outlet is connected with the other end of groove 10.It is situated between that is, entering the cooling of heat exchanger channels from import
Matter can only flow into the other end of cooling duct from one end of cooling duct, finally flow out from outlet.The cooling of the structure is logical as a result,
Road can guarantee the heat exchange area of cooling medium Yu stator 100, so that the heat exchange efficiency of motor be effectively ensured.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit the protection of the utility model
Range is solved as long as that in body design thought of the invention and mentally makes has no the change of essential meaning or polishing
Certainly the technical issues of, is still consistent with the present invention, should all be included within protection scope of the present invention.
