A kind of electric machine casing, it comprises outer shell and hypostracum, between described outer shell and the hypostracum cooling water channel is set, the contact-making surface of described outer shell and hypostracum is tightly connected, and on the surface of described outer shell away from cooling water channel projection is set.
Further improve, described projection circumferentially or axially is provided with along described outer shell.
Further improve, described projection is along circumferential formation annulus, the center of described annulus and the central axes of motor of described outer shell.
Further improve, described projection is the shape of threads setting on described outer shell surface.
Further improve the spirality setting vertically of described cooling water channel, the corresponding setting of described shape of threads projection with cooling water channel.
Further improve, described projection also comprises at least one strip bulge, and described strip bulge is along the axial setting of described shell body 1.
Further improve, described strip bulge is 6, and described 6 strip bulges are evenly distributed on the surface of described outer shell.
Further improve, described electric machine casing also comprises two end caps, and described two end caps are tightly connected with described hypostracum and described outer shell respectively.
The utility model compared with prior art owing to be provided with projection on outer shell, has increased the contact area of outer shell and air, has improved radiating condition, helps reducing fast the temperature of water in the cooling water channel, has improved the radiating efficiency of motor.

Fig. 2 is the cutaway view at A-A place among Fig. 1.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
According to a kind of execution mode of the present utility model, shown in Fig. 1-2, a kind of electric machine casing, it comprises outer shell 1 and hypostracum 2, between described outer shell 1 and the hypostracum 2 cooling water channel 3 is set, the contact-making surface of described outer shell 1 and hypostracum 2 is tightly connected, and projection 4 is set on the surface of described outer shell 1 away from cooling water channel 3.
The contact-making surface of described outer shell 1 and hypostracum 2 is tightly connected and can adopts welding or be coated with fluid sealant on contact-making surface, the outer shell 1 of motor and the contact area of air have been increased by described projection, accelerate the heat radiation of motor housing layer 1, reduce the temperature of water in the cooling water channel 3, improved the radiating efficiency of motor.
Described projection can have a lot of forms, and for example: the cross section is the form that zigzag, waveform, triangle etc. can increase outer shell 1 and air contact area, here repeats no more.
Further improve, described protruding 4 along the circumferential of described outer shell 1 or axially setting, makes the processing of described electric machine casing simpler, also makes electric machine casing more attractive in appearance.
Further improve, described protruding 4 circumferential formation annulus along described outer shell 1, the center of described annulus and the central axes of motor, described annulus have not only increased the contact area of described outer shell 1 and air, have also increased the mechanical strength of described outer shell 1 simultaneously.
The axial cross section of described annulus can be trapezoidal, rectangle, triangle etc., as long as can increase the shape of outer shell 1 and air contact-making surface.
Further improve, described protruding 4 are the shape of threads setting on described outer shell 1 surface, its effect of bringing is the same along the circumferential formation annulus 41 of described outer shell 1 with described protruding 4, but when the spirality setting vertically of described cooling water channel 3, described shape of threads projection 4 and cooling water channel 3 corresponding settings, make described shape of threads projection more approaching, reduced the conduction distance of heat, make heat radiation rapider with cooling water channel.
Further improve, described protruding 4 also comprise at least one strip bulge 41, and described strip bulge 41 is along the axial setting of described shell body 1, and those skilled in the art know, can strengthen the mechanical strength of described electric machine casing, further increase the contact area of described outer shell 1 and air simultaneously.
Further improve, described strip bulge 41 is 6, and described 6 strip bulges 41 are evenly distributed on the surface of described outer shell 1, and equally distributed design helps the average force of motor, and the while is better appearance also.
Further improve, described electric machine casing also comprises two end caps 6, and described two end caps 6 are tightly connected with described hypostracum 2 and described outer shell 1 respectively.
