Abstract
The utility model provides a heat dissipation structure of a motor controller. The heat dissipation structure of the motor controller comprises a pipeline and the motor controller, wherein the motor controller is mounted in the pipeline and comprises a housing, and the side surface of the housing is tightly bonded with the inner wall of the pipeline. The heat dissipation structure of the motor controller takes the pipeline such as a frame tube of an electric bicycle as an auxiliary heat dissipation body of a power part of the motor controller, thereby leading the motor controller to be in tight contact with the inner wall of the frame tube, effectively dissipating heat generated during the working process of the motor controller, reducing the temperature difference between the interior and the exterior of the motor controller and prolonging the service life of the motor controller. Besides, the motor controller is arranged in the frame tube, which is conductive to integral design and manufacture of the whole electric bicycle.

Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Fig. 1 is the schematic diagram of the utility model embodiment.As shown in Figure 1, the radiator structure of electric machine controller comprises electric machine controller 11 and pipeline 12.
In the present embodiment, the shape of the side 114 of housing 111 is consistent with the inwall 12a shape of pipeline 12.Yet, in other embodiments, also being provided with heat-conducting block 116 on the side 114, the shape on heat-conducting block 116 surfaces is consistent with the inwall 12a shape of pipeline 12 (vehicle frame pipe), and side 114 fits tightly by the inwall 12a of heat-conducting block 116 with pipeline 12.
In the present embodiment, in the side of housing 111, the power component 112a on the circuit board 112 is approached in side 114.
In the present embodiment, electric machine controller 11 also comprises end cap 117, is arranged on an end of housing 111, and above-mentioned end cap 117 is car pipe lids of pipeline 12 (vehicle frame pipe).The other end of electric machine controller 11 housings 111 is openings, is used for external rat tail 118.
When electric machine controller 11 is installed in the pipeline 12 (vehicle frame pipe), the shape on heat-conducting block 116 surfaces on the side 114 is consistent with the inwall 12a shape of pipeline 12 (vehicle frame pipe), under the effect of flexible member 113, side 114 closely contacts with heat-conducting block 116, heat-conducting block 116 fits tightly with the inwall 12a of pipeline 12 (vehicle frame pipe), and under the effect of flexible member 113, the inwall of side 21a and vehicle frame pipe 103 can be realized fitting tightly, like this, during electric machine controller 11 work, the heat that power component 112a produces on its internal circuit plate 112 can be by housing 111, to heat-conducting block 116, the metal that arrives a series of tight contacts of vehicle frame pipe 12a is delivered to vehicle frame pipe 12 to outside air fast by heat conduction.。
The utility model makes electric machine controller closely contact with pipeline (for example vehicle frame pipe of electric bicycle) inwall, utilize the auxiliary heat dissipation body of pipeline as the power component electric machine controller, increase the area of dissipation of power device, the high heat that produces during the controller that effectively leaves work.To reducing the conduit controller internal-external temperature difference, prolong product and can both play good effect useful life.Further, conduit controller is arranged in the vehicle frame pipe, has and utilize the volume that reduces the electric bicycle car load.
Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
