In controller for electric vehicle, power switch pipe (metal-oxide-semiconductor) has small volume, and caloric value is large, the feature that heat generation density is high, most controllers are all provided with heat abstractor and distribute with the high heat that its work is produced, and make it not affect controller until the normal operation of car load because crossing cause thermal damage.
Heat abstractor includes a radiating seat, radiating seat arranges cavity conventionally, cavity inner bottom surface arranges PCB circuit board, one sidewall is arranged side by side some power switch pipes, described power switch pipe electrical connection PCB circuit board, in the radiating seat of existing controller, is fixed on some power switch pipes separately on one aluminum strip by bolt, form power switch pipe in a row, and then aluminum strip is close on a madial wall of radiating seat cavity and carries out heat loss through conduction.Therefore in installation process, power switch pipe need be arranged on aluminum strip in turn, and then aluminum strip is connected and carries out heat loss through conduction with the sidewall of radiating seat.Therefore there is following drawback: bolt that need to be identical with power switch pipe quantity when 1, power switch pipe is locked on aluminum strip, and controller is managed even more according to different 6 pipes, 9 pipes, 12 pipes, 15 pipes, 18 of dividing of the quantity of power switch pipe, too much bolt is installed not only spended time, install not convenient, and the corresponding manufacturing cost that increased; 2, the bolt that power switch pipe connects will be by the thermal component of power switch pipe, and between bolt and power switch pipe, creepage distance is limited, can not meet the requirement of high pressure resistant insulation resistance; 3, heat dissipation path is power switch pipe---aluminum strip---mount pad, cause its heat dissipation path longer, thermal resistance strengthens, the heat that power switch pipe work produces can not distribute faster, in the time that the higher operating mode of ambient temperature is comparatively severe, power switch pipe can, because of the cause thermal damage of can not dispelling the heat in time, cause car load normally not move.
Utility model content
The utility model is the deficiency existing for current electric motor car heat abstractor, and a kind of controller for electric vehicle heat abstractor overcoming the above problems is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of controller for electric vehicle heat abstractor, described heat abstractor includes a radiating seat that cavity is set, and the inner bottom surface of described cavity arranges PCB circuit board, and a sidewall is arranged side by side some power switch pipes, described power switch pipe electrical connection PCB circuit board; In described cavity, arrange on the sidewall of power switch pipe mounting plane is set, power switch pipe is arranged side by side on mounting plane, and a press strip lid is pressed on described power switch pipe in a row, and the plural bolt of arranged outside of radiating seat is connected to press strip.
Preferably, the periphery of described radiating seat arranges fin.
Preferably, the setting that concaves at mounting plane place of described sidewall, arranged outside becomes bolt mounting plane.
Preferably, between described power switch pipe and mounting plane, insulating trip is set.
Preferably, soft cushion pad is set between described press strip and power switch pipe.
Preferably, described soft cushion pad is silicagel pad.
The beneficial effects of the utility model are, controller for electric vehicle heat abstractor of the present utility model, in described radiating seat cavity, arrange on the sidewall of power switch pipe mounting plane is set, power switch pipe is arranged side by side on mounting plane, one press strip lid is pressed on described power switch pipe in a row, and the plural bolt of arranged outside of radiating seat is connected to press strip; The utility model controller heat abstractor is pressed in the press strip on power switch pipe in a row by the bolted cap that is arranged on outside, realize power switch pipe and ride over the object on radiating seat, rare several bolt just can be realized the fixing of numerous power switch pipes, and without aluminum strip is installed, have quick and easy for installation, simplify production technology, reduced the feature of production cost; In addition, when constant power switching tube, bolt is realized power switch pipe by press strip and is overlayed the inwall at radiating seat, and bolt is not directly by power switch pipe, and between bolt and power switch pipe, creepage distance is enough, meets the requirement of high pressure resistant insulation resistance completely; Again, power switch pipe rides over radiating seat and directly dispels the heat and save this heat dissipation path of aluminum strip than existing controller, and heat dissipation path is shorter compared with the radiating seat of traditional heat-dissipating device, and heat can be distributed faster, greatly reduces its overheated spoilage, strengthens its useful life.
