Description
Technical Field
The utility model relates to an electronic water pump technical field specifically is a controller location structure that electronic water pump was used.
Background
With the rapid development of electric vehicles, components on the electric vehicles are also developed at a rapid pace. The components such as a battery, a motor and a motor controller on the electric automobile can generate a large amount of heat in the working process, and the electric automobile cancels a traditional internal combustion engine, so the electric automobile can not rely on a mechanical water pump to provide cooling, and the automobile electronic water pump is generated under the background. Among the present electronic water pump, generally mutually support through controller control rotor and stator, drive the impeller and rotate, among the present electronic water pump, the controller is the connected mode of contact between adopting mostly with motor casing, only scribbles the heat dissipation silicone grease between controller and the motor casing, because there is not the space between controller and the motor casing, such connected mode causes poor stability and insulating thermal diffusivity low scheduling problem easily.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a controller location structure that electron water pump was used.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
a controller positioning structure for an electronic water pump comprises a bearing base and a controller, wherein a heat dissipation pad is arranged between the bearing base and the controller, the heat dissipation pad is of an annular structure, positioning columns are arranged on two opposite sides of the end faces of the two sides of the heat dissipation pad, and positioning grooves matched with the positioning columns are correspondingly arranged on the bearing base and the controller;
the bearing base, the controller and the heat dissipation pad are detachably connected.
As a further improvement, the heat dissipation pad is made of high temperature resistant material, and the thickness is 3-5 mm.
As a further improvement, all be equipped with on bearing pedestal, controller and the heat dissipation pad and be used for with screw complex screw thread mounting hole, the circumferencial direction equipartition is followed to the screw thread mounting hole.
The utility model has the advantages that:
the utility model discloses a set up the annular heat dissipation pad of being made by high temperature resistant material between bearing base and controller, keep apart bearing base and controller, avoided direct contact, then through two-sided heterotypic hole location, connect bearing base and controller; the heat dissipation requirement of the electronic water pump under high-speed operation is effectively guaranteed, and the service life of the controller and the electronic water pump is remarkably prolonged.

Detailed Description
In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 4, a controller location structure for electronic water pump, including bearing base 1, controller 2, be equipped with the cooling pad 3 between bearing base 1 and the controller 2, the cooling pad 3 is the loop configuration, the cooling pad 3 is made for high temperature resistant material, and thickness is 3-5 mm, relative both sides on the both sides terminal surface of cooling pad 3 all are equipped with reference column 31, wherein two reference columns 31 on the left side terminal surface are compared with two reference columns 31 on the right side terminal surface and are compared that length is shorter and front and back symmetric distribution, two reference columns 31 staggered distribution on the right side terminal surface, two reference columns 31 on the left side terminal surface with the constant head tank 4 cooperation that bearing base 1 corresponds the setting, two reference columns 31 on the right side terminal surface with the constant head tank 4 cooperation that corresponds the setting on the controller 2; the double-sided ectopic hole is adopted for positioning, so that the connection stability between the controller and the motor shell can be effectively ensured when the electronic water pump works; keep apart bearing pedestal 1 and controller 2 through the cooling pad 3, avoided direct contact between bearing pedestal 1 and the controller 2, made to leave the space between the two, improved its insulating heat dispersion, further arrange heat dissipation silicone grease in the space between the two, can further improve the thermal diffusivity of electronic water pump and controller.
The bearing base 1, the controller 2 and the heat dissipation pad 3 are respectively and correspondingly provided with four threaded mounting holes 5, the threaded mounting holes 5 are uniformly distributed along the circumferential direction, and the bearing base 1, the controller 2 and the heat dissipation pad 3 are fixedly connected through screws matched with the threaded mounting holes 5; the screw is connected in a detachable mode, so that the inspection and maintenance are convenient.
During the installation, fix bearing base 1 on motor casing earlier, then correspond the block through reference column 31 on the terminal surface of the 3 left sides of cooling pad and bearing base 1 constant head tank 4, then, arrange heat dissipation silicone grease on the terminal surface of the middle part bearing base 1 of cooling pad 3, then correspond the block with constant head tank 4 on the 2 terminal surfaces of controller and reference column 31 on the 3 right sides terminal surfaces of cooling pad, finally, twist screw 6 in four threaded mounting holes 5 and accomplish being connected of controller and motor casing.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and these changes and modifications are intended to fall within the scope of the present invention as claimed.
