For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of brushless motor controller radiator structure, comprise the controller housing of being made by aluminum alloy materials, described controller housing is rectangle box body structure, in described controller housing, controller circuit board is installed, described controller housing inside is symmetrically arranged with raised line in left and right sides wall bottom, described controller circuit board is installed on raised line, the surface distributed of described controller housing has heat radiation striped, described controller housing bottom is provided with the radiator that aluminum alloy materials is made, described radiator comprises top board, the described top board left and right sides is vertically installed with side plate, described top board is provided with fin between biside plate, described top board both sides and side plate side are provided with outstanding laterally flank, the left and right sides, described controller housing bottom is provided with side plate, described top board flank and side plate are bolted, the flank of described side plate is fixed by bolt and frame.
Preferably, four jiaos of screwed holes that are provided with for static controller circuit board of described controller housing inner bottom surface, screw is fixed controller circuit board by screwed hole, and controller housing front/rear end two bottom sides is provided with for the fixing screwed hole of end cap.
Preferably, described fin bottom surface is concordant with side plate bottom surface, and described fin extends along radiator length direction.
Preferably, described heat radiation striped is distributed in controller housing end face and side and extends along controller housing length direction.
The brushless motor controller shell of the utility model design, surface distributed has heat radiation striped, greatly increased the surface area of controller housing, strengthened the radiating effect of self, the more important thing is, the radiator that is aided with particular design in controller housing bottom, it can better, for controller dispels the heat, reduce the harmful effect of heating to controller.
Therefore, the utility model is simple in structure, cheap, and simple installation has improved the heat-sinking capability of controller greatly, solves the poor problem of brushless motor controller radiating effect.

Embodiment
Below in conjunction with Fig. 1 to Fig. 3, illustrate embodiment of the present utility model.
A kind of brushless motor controller radiator structure, comprise the controller housing 2 of being made by aluminum alloy materials, described controller housing 2 is rectangle box body structure, in described controller housing, controller circuit board is installed, and described controller housing bottom is provided with the radiator 1 that aluminum alloy materials is made.
Described controller housing 2 inside are symmetrically arranged with raised line 202 in left and right sides wall bottom, and described controller circuit board is installed on raised line, and the surface distributed of described controller housing has heat radiation striped 204.
Described controller housing 2 bottoms are provided with the radiator 1 that aluminum alloy materials is made, described radiator comprises top board 11, the described top board left and right sides is vertically installed with side plate 12, described top board is provided with fin 14 between biside plate, described top board both sides and side plate side are provided with outstanding laterally flank 13, flank edge is provided with flank fixing hole 15, and the left and right sides, described controller housing bottom is provided with side plate 205, and side plate corner is provided with side plate fixing hole 206.Described top board flank and side plate are bolted, and the flank of described side plate is fixed by bolt and frame.
Concrete, 201 4 jiaos of first screwed holes 203 that are provided with for static controller circuit board of described controller housing inner bottom surface, screw is fixed controller circuit board by the first screwed hole, and controller housing front/rear end two bottom sides is provided with for fixing the second screwed hole of end cap.Described fin bottom surface is concordant with side plate bottom surface, and described fin extends along radiator length direction.Described heat radiation striped is distributed in controller housing end face and side and extends along controller housing length direction.
In order further to improve radiating effect, also controller housing 2 has been done to further improvement, as shown in Figure 4, controller housing 2 comprises base 21, upper cover 22, and the cross section of base 21 and upper cover 22 is all U-shaped, during installation, base is at bottommost, and upper cover covers base from base top.
As shown in Figure 5, the side of base 21 is respectively equipped with ground floor bending part 211 and second layer bending part 212 in lateral, ground floor bending part and second layer bending part are to be all L-type bending, just fit and be positioned at ground floor bending part 211 in two U-shaped flank bottoms of upper cover, so ground floor bending part has just been realized the limit function to the position, left and right of upper cover, between base ground floor bending part inner side and base, be provided with circuit board fixing groove 213, by circuit board fixing groove 213, the circuit board of controller can be embedded in circuit board fixing groove, simple in structure, effect is remarkable, the bending of second layer bending part 212 is mainly in order to form a new clearance space between upper cover medial surface and base side, in this clearance space, namely between upper cover medial surface and second layer bending part, be provided with cooling pipe 23, the import of cooling pipe is communicated with and introduces the cold wind of fan generation with the fan of motor, cooling pipe is provided with air outlet in this clearance space, cold wind process cooling pipe also blows out through air outlet, make the air of flowing through accelerate convection current, can cool to the upper cover side of cooling pipe process simultaneously, also base side that can be to opposite side, be that second layer bending part also has the effect that necessarily cools, because be aluminum alloy material, there is good thermal conductivity, so second layer bending part is when being cooled, cooling effect can be extended into whole base, preferably, described second layer bending part is provided with the radiating groove 214 of paliform, radiating groove is conducive to the circulation of air of the second bending part inner side to the cooling pipe place in outside, realize convection current, contribute to inner air to cool.In addition, cooling pipe preferably consists of side by side 2 above S bend pipe roads, and cooling pipe fore-and-aft direction runs through the side of whole upper cover, and the cooling pipe area coverage of flexure type is larger, when cooling, maximum magnitude has covered whole upper cover side, makes cooling heat dissipation effect reach best.
Because brushless electric machine is in when work, fan is worked always, and cooling pipe is introduced the cold wind that fan produces, and cold wind is guided upper cover into around and enters controller housing inside through cooling pipe, and the cross-ventilation in the region of having accelerated to flow through, has improved cooling effect.
