[detailed description of the invention]

In order to make the purpose of this utility model, technical scheme and advantage are more clear Chu Mingbai, below in conjunction with accompanying drawing and embodiment, is carried out this utility model Further describe.Should be appreciated that specific embodiment described herein Only in order to explain this utility model, it is not used to limit this utility model.

Refer to Fig. 1 and Fig. 2, this utility model first embodiment motor radiating Device 1 includes a chassis 11, and the middle part on this chassis 11 is discoid, its radius For r, the center arranges a big hole 111, when mounted rotor (figure Depending on) steel axle can pass at this big hole 111.Described big hole 111 Be arranged around 4 apertures 112, it is for being fixed on electric machine radiator 1 The two ends of rotor.The edge on described chassis 11 is evenly distributed odd number Flat blade 113, this flat blade 113 is the tip-angled shape protruding from edge, chassis 11 Blade, it includes the first limit 1131 and the second limit 1132, this first limit 1131 And second α at an acute angle between limit 1132.

This electric machine radiator 1 farther includes multiple vertical blade 13, this vertical leaf The quantity of sheet 13 matches with described flat blade 113, and it is integrally connected to respectively Corresponding flat blade 113.Each vertical blade 13 includes integrated egative film Dististyle 132 before 131 and one, this egative film 131 is the most at an angle with front dististyle 132 Connecting, this egative film 131 is triangular in shape, its base and the second of flat blade 113 Limit 1132 overlaps and entirety is perpendicular to face, place, chassis 11, its of this egative film 131 His two limits (first hypotenuse 1311 and the second hypotenuse 1312) length is equal, First hypotenuse 1311 is inside chassis 11, and the second hypotenuse 1312 connects front end Sheet 132.Described front dististyle 132 is trapezoidal, and it includes the upper end parallel to each other 1321 and go to the bottom 1322 and be positioned at two waists 1323 of the left and right sides (in institute Having in embodiment, upper and lower, left and right, the position determiner such as inside and outside are only The relative position being limited in given view, rather than absolute position), wherein one is oblique Limit 1321 overlaps with the second hypotenuse 1312 of described egative film 131, whole front dististyle 132 with egative film 131 in an obtuse angle and flat to its place of vertical blade 13 entirety Bend at blade 113.

In the present embodiment, the wedge angle α of flat blade 113 is 60 °, its first limit 1131 and second the length on limit 1132 equal, and its a length of chassis 11 disk The half of radius r；First hypotenuse 1311 and the second hypotenuse 1312 of egative film 131 Length equal, this face, egative film 131 place is vertical with face, flat blade 113 place； The outer waist 1323 of front dististyle 132 is perpendicular to He of the upper end parallel to each other 1321 Go to the bottom 1322, the length of the upper end 1321 of this front dististyle 132 and its place flat blade Second limit 1132 of 113 is equal, and this front dististyle 132 is angled with egative film 131 institute Between 120 °～175 °, preferred value is 150 °～175 °.Such parameter designing The eddy current wind that heat abstractor 1 can be made not only to produce in rotation is big, and air The impact that resistance produces is relatively small, so that the eddy current that heat abstractor 1 produces Wind maximizes.

Refer to Fig. 3, this utility model the second embodiment electric machine radiator 2 Including a chassis 21, the edge on this chassis 21 is evenly distributed the flat leaf of odd number Sheet 213, this electric machine radiator 2 farther includes multiple vertical blade 23, its Quantity is equal with described flat blade 213, and this vertical blade 23 is integrally connected to respectively Multiple flat blades 213.Each vertical blade 23 is a trapezoidal faces, and it includes mutually The parallel upper end 231 and go to the bottom 232 and two waists 233, its go to the bottom 232 from End point overlaps to the part at midpoint and the second limit 2132 of flat blade 213, Go to the bottom 231 two times of a length of second limit 2132 length, described trapezoidal for appointing Anticipate trapezoidal, preferably right-angled trapezium, and the waist outside electric machine radiator 2 233 are perpendicular to go to the bottom 232.Deforming as one, each vertical blade 23 is permissible For arbitrary quadrilateral, the angle between this vertical blade 23 and flat blade 213 between Between 60 °～120 °, preferably 90 °.Deform as another kind, each vertical leaf 232 parts from end point to midpoint of going to the bottom of sheet 23 can be with flat blade First limit 2131 of 213 overlaps.Except the structure of vertical blade 23 is implemented with first Outside example difference, other structure and parameters of this second embodiment are all with first Embodiment is identical.

In both examples above, vertical blade 13 (23) is overall in up time Pin direction bends, and the direction of rotation of this electric machine radiator 1 (2) entirety is also For clockwise, the quantity of its flat blade 113 (213) and vertical blade 13 (23) is equal And it being all 11, its quantity is not construed as limiting, and can be any odd number.Will The quantity of flat blade 113 (213) and vertical blade 13 (23) is set to odd number, phase For even number, electric machine radiator 1 whole machine balancing degree can be made slightly to drop Low, so that it produces bigger eddy current wind in rotary course, increase Wind-force so that it is radiating effect is more preferable.

Compared with prior art, this utility model electric machine radiator 1 (2) By the quantity of flat blade 113 (213) and vertical blade 13 (23) is arranged For odd number, electric machine radiator 1 (2) whole machine balancing degree is made slightly to reduce, So that it produces bigger eddy current wind in rotary course, increase wind-force, Make its radiating effect more preferable.By its parameter being arranged to the point of flat blade 113 Angle is 60 °, and the length on its first limit 1131 and the second limit 1132 is equal, and its The half of a length of chassis 11 disc radius r；First hypotenuse of egative film 131 1311 and second the length of hypotenuse 1312 equal, this face, egative film 131 place is with flat Face, blade 113 place is vertical；The outer hypotenuse 1321 of front dististyle 132 is vertical In upper and lower two parallel edges 1322, this front dististyle 132 parallel edges 1322 below Length is equal with the second limit 1132 of its place flat blade 113, this front dististyle 132 is angled between 120 °～175 ° with egative film 131, and preferred value is 150 ° ～175 °, the eddy current wind making electric machine radiator 1 not only produce in rotation is big, And the impact of air drag generation is relatively small, so that heat abstractor 1 produces Eddy current wind maximize.

The foregoing is only preferred embodiment of the present utility model, not In order to limiting this utility model, all made within principle of the present utility model Any amendment, equivalent and improvement etc. all should comprise protection of the present utility model Within the scope of.
