Description
Technical field
The utility model relates to the heat dissipation technology field of controller for electric vehicle, more specifically, relates to a kind of radiator structure of controller for electric vehicle.
Background technology
The various harm that bring in order to reduce environmental pollution, the use of electric motor car is more and more frequent, controller for electric vehicle is as the core control part of electric motor car, both judgement and the control of the each signal of electric motor car had been born, also born the switching function of power section simultaneously, because the circulating current of power section is larger, the electric current of single metal-oxide-semiconductor is limited, normally several even tens be connected in parallel composition large switching tubes.In the time that metal-oxide-semiconductor is a lot, metal-oxide-semiconductor and the heat dissipation metal base plate tight difficulty of fitting is larger, and radiating effect is poor, easily causes local overheating and damages metal-oxide-semiconductor.
Traditional metal-oxide-semiconductor is some deficiency below existing aspect heat radiation: one: metal-oxide-semiconductor need to be fitted and connected and carry out heat conduction on heat conduction aluminum strip, and heat conduction aluminum strip is connected on shell more afterwards, and the metal-oxide-semiconductor of heating is reached heat on shell and dispels the heat by heat conduction aluminum strip.Because the link of metal-oxide-semiconductor and heat conduction aluminum strip is copper layer, copper material cannot be connected with welding manner with aluminium material, and each metal-oxide-semiconductor needs the screw by insulating case is housed to be fixed on aluminum strip.After insulating case is pre-assembled with screw needs, be connected metal-oxide-semiconductor and heat conduction aluminum strip, operation is loaded down with trivial details.Its two: multiple metal-oxide-semiconductors are connected on heat conduction aluminum strip side by side, the disposal that needs to insulate between each metal-oxide-semiconductor, first coats dielectric film after heat-conducting silicone grease when conventional mounting, is placed on heat conduction aluminum strip, again metal-oxide-semiconductor is placed on dielectric film, and by screw, metal-oxide-semiconductor is fixed on aluminum strip one by one.Not only efficiency is low, poor reliability to play one by one screw, and insulating case is often heated easily agingly, causes screw loosening, thereby makes metal-oxide-semiconductor fault.Metal-oxide-semiconductor is fixed on aluminum strip on shell after being welded on circuit board, and the caloric value of metal-oxide-semiconductor is passed to shell by pressing plate, dielectric film, aluminum strip, and the thermal resistance of dielectric film own is larger, and overall heat transfer efficiency is low.Its three: in order to strengthen current path, increase the sectional area of current lead-through, tend to take to be welded with the method for copper bar, be welded with copper bar the heat producing cannot be derived, easily caused cause thermal damage.
Existing notification number is that the patent of CN202050699U discloses a kind of electric bicycle controller heat dissipation device, comprise and be provided with the printed circuit board of integrated circuit, the back side that metal-oxide-semiconductor is fixed on printed circuit board (PCB), the another side of metal-oxide-semiconductor is fixed with aluminum strip, and described aluminum strip is fixed on aluminium box by insulating barrier.
