Description
Technical field
The utility model relates to a kind of controller, specifically FOC controller.
Background technology
Controller is as the core component in electronic car load electric system, and its reliability plays vital effect to the reliability of car load, and wherein the heat dissipation design of power device becomes one of core design wherein just gradually.In traditional industry, heat dissipation design adopts screw that power device is locked on radiator, must add one deck insulating radiation material simultaneously and transmit to guarantee insulation and heat between electronic unit and shell between power device and radiator.Adopt such design to have following several defects: whether the locking of screw puts in place can not guarantee in large batch of production process, and single power device is overheated to be burnt once the bad meeting that locks causes; Insulating radiation material between power device and fin has reduced heat conducting speed, causes the heat of power device in long-time heavy load situation effectively not pass, and causes heat to gather and causes the hydraulic performance decline of controller even to burn.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides the battery case metal shell that utilizes of a kind of good heat dissipation, stable performance to make the aluminium base FOC controller of radiating surface.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of aluminium base FOC controller that utilizes battery case metal shell to do radiating surface, the battery case metal shell and the electric capacity that comprise aluminum base PCB plate, fit with it, on aluminum base PCB plate and battery case metal shell, be provided with the electric capacity of laying electric capacity and lie down sinking space, electric capacity is arranged on electric capacity and lies down in sinking space.
After scribbling heat-conducting cream on the radiating surface of described aluminum base PCB plate, be fitted on battery case metal shell.
Described aluminum base PCB plate and battery case metal shell are screwed connection.
Also comprise paster power device, paster power device is welded on aluminum base PCB plate.
On aluminum base PCB plate, be also provided with metal weld tabs, described electric capacity is lied down at electric capacity and is lied down in sinking space, and its pin is welded on metal weld tabs.
The utility model paster power device is attached on aluminum base PCB plate, and aluminum base PCB plate radiating surface has been brushed after heat-conducting cream, is close to battery case metal shell, uses screw locking.Battery case metal shell is directly exposed in air, utilizes the car load Air Flow in process of riding to take away heat, reaches air-cooled effect.Battery case metal shell digs out a part of space in electric capacity installation site according to the shape of electric capacity, electric capacity can be lain low and sink in shell, reduces the height of product.Use a metal weld tabs that can do Surface Mount, capacitor pin can be soldered directly on metal weld tabs, has reduced welding difficulty, reduces the technology difficulty of production.
Beneficial effect: the utility model adopts aluminium base as main heat-conduction medium, radiating effect promotes obviously, and assembling is simple, goes for most of power density large, the occasion that unit are heat load is heavier.Adopt metal weld tabs as the interface unit between aluminium base and electric capacity, solve the difficulty of element welding on aluminium base.The structure that adopts electric capacity to sink, has solved at some space than the space utilization problem of more sensitive application scenario.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of aluminium base FOC controller that utilizes battery case metal shell to do radiating surface, paster power device 6 is welded on aluminum base PCB plate 1, the radiating surface of aluminum base PCB plate 1 fits on battery case metal shell 2 after being coated with heat-conducting cream, uses screw 5 that aluminum base PCB plate 1 is locked on battery case metal shell 2.Electric capacity 3 is first put into the electric capacity digging out on battery case shell 2 and is lied down sinking space 4, and its pin is welded on metal weld tabs 7.
This controller used a kind of better simply method to solve the heat conducting speed issue of power device, also solved the heat that radiator gathers and has been delivered to fast an airborne difficult problem.Adopt paster weld tabs to solve the Welding Problems of high-voltage large-capacity aluminium electroloysis simultaneously.The structure matching that adopts electric capacity to sink to battery case solves the excessive height problem that may cause on space.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
