Adhere to, accelerate flow velocity to ensure the electric machine casing of cooling effect.
The purpose of this utility model can be realized by following technical proposal：A kind of electric machine casing, including it is tubular
Inner casing and shell, described shell is placed on inner casing outside and both two ends mutually seal, and the outer surface of described inner casing is provided with spiral shell
The groove one for revolving shape and the spiral dividing plate one for preventing medium channelling in groove one, outer surface one end of described shell sets
There is import, the other end is provided with outlet, and described inlet and outlet is connected with groove one, it is characterised in that described groove
One bottom surface middle part has spiral raised one and groove one is recessed arcwall face one in the bottom surface of a raised both sides,
To arcwall face one, the inner surface of described shell is provided with the He of helical groove two to the edge arc-shaped transition of described raised one
Prevent the spiral dividing plate two of medium channelling in groove two, the bottom surface middle part of described groove two has spiral convex
Play two and groove two is recessed arcwall face two in the bottom surface of raised two both sides, described raised two edge arc-shaped transition is extremely
Arcwall face two, described dividing plate one and dividing plate two-phase clamping causes that groove one and groove two are collectively forming medium runner.
In a kind of above-mentioned electric machine casing, described dividing plate one offers spiral helicine draw-in groove, and described dividing plate two has
Fixture block that have protrusion and that helical form is snapped in draw-in groove.During installation, by dividing plate two and the position alignment of dividing plate one, fixture block is set just to block
In draw-in groove, shell is relatively rotated with inner casing afterwards, complete the assembling of shell and inner casing, after easy to assembly and assembling every
The barriering effect of plate one and dividing plate two is good.
In a kind of above-mentioned electric machine casing, the outer surface of described shell has multi-disc fin.The temperature of inner casing by
Dividing plate one, dividing plate two can reach shell, and the temperature of medium is directly transferred to shell, and fin serves further radiating to shell and makees
With.
Compared with prior art, this electric machine casing will not be provided at attachment for the dirt in current or fluid, and dirt can be with
Medium flows out medium runner, is that motor long-time normal work improves safety guarantee in the absence of risk is blocked, and smooth
Arcwall face one, arcwall face two do not result in turbulent flow, and velocity of medium is fast, can quickly take away heat, and cooling performance is good.

Specific embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this electric machine casing includes tubular inner casing 1 and shell 2, inner casing 1 and shell 2 by
The aluminium alloy that good corrosion resistance, thermal conductivity are good and thermal diffusivity is good is made.Shell 2 is placed on the outside of inner casing 1, and both two ends compared with
Technology is the same, is mutually sealed by sealing ring, capping, and the outer surface of inner casing 1 is provided with helical groove 1 and prevents groove one
The spiral dividing plate 1 of medium channelling in 3, outer surface one end of shell 2 is provided with import 5, and the other end is provided with outlet 6, enters
Mouthfuls 5 and outlet 6 be connected with groove 1, the bottom surface middle part of groove 1 with spiral raised 1 and groove 1 in
The bottom surface of raised one 7 both sides is recessed arcwall face 1, raised 1 edge arc-shaped transition to arcwall face 1, shell 2
Inner surface is provided with helical groove 29 and prevents the spiral dividing plate 2 10 of medium channelling in groove 29, groove two
9 bottom surface middle part has spiral raised 2 11 and groove 29 is recessed arc in the bottom surface of raised 2 11 both sides
Face 2 12, raised 2 11 edge arc-shaped transition to arcwall face 2 12, dividing plate 1 and the phase clamping of dividing plate 2 10 causes groove 1
Medium runner 13 is collectively forming with groove 29.
