Abstract
The utility model provides an electric vehicle controller, includes cuboid casing, bottom and installs at the inside control panel of casing, characterized by, casing upper portion establish and open a plurality of discharge fan that stop by control panel control, if rectangular form heat dissipation bars are done to all the other each surfaces, if the bottom do rectangular form air inlet, fixed surface has the temperature sensor for control panel transmission temperature signal in the casing. Through the inside temperature of temperature sensor survey controller, the number of control panel control discharge fan start -up can be dispelled the heat and the ability make full use of energy avoids causing the energy extravagant effectively, rectangular form heat dissipation bars are established to casing surface all around, increase the area of contact of housing face and outside air, increase the radiating effect, rectangular form air inlet is established to the bottom, makes that to admit air the area extensively even more, and the radiating effect is better.
Description
Technical field
The utility model belongs to electric automobile field, specifically a kind of electric vehicle controller.
Background technology
In the modern life, electric energy replaces gasoline to drive the electric automobile of automobile more and more general, and electric energy belongs to secondary energy sources, and its source is varied, is used on automobile and drives automobile can accomplish real nothing discharge.But existing electric automobile does not generally have gearbox, voltage or electric current just by changing motor carry out speed change.The startup of the signal control motor that motor is transmitted by controller, stopping and rotating speed, motorized motions and control are the core contents of electric automobile.Except improving battery energy density and life-span, reducing costs, the reliability improving electric vehicle controller is task very urgent at present.Controller is the critical component that driving that the alternating current electricity consumption of the powered by direct current and motor realizing battery converted, realized motor runs, and belongs to electric motor car core power parts, requires that it can continue reliable operation.Present electric vehicle controller ubiquity heat radiation is bad, and cooling system arranges irrational problem, thus affects the useful life of controller.
Summary of the invention
Arrange unreasonable for solving electric vehicle controller cooling system now, the problem that controller useful life is short, the utility model provides a kind of electric vehicle controller.
The utility model is realized by following technical proposals.
A kind of electric vehicle controller, comprise cuboid housing, bottom and be arranged on the control board of enclosure interior, it is characterized in that, described housing upper establishes the some scavenger fans being controlled start and stop by control board, and all the other each outer surfaces establish some strips to dispel the heat grid; Described bottom establishes some strip air inlets; Shell inner surface is fixed with to the temperature sensor of control board transmission temperature signal.
Described electric vehicle controller, wherein, described scavenger fan quantity is 4.
Described electric vehicle controller, wherein, described housing, bottom and heat radiation grid material are aluminium.
The beneficial effects of the utility model are: this electric vehicle controller, and by temperature sensor measurement controller internal temperature, control board controls the number that scavenger fan starts, and effectively can dispel the heat and can make full use of the energy, avoiding causing energy waste; Housing surrounded surface establishes strip heat radiation grid, increases the contact area of surface of shell and outside air, increases radiating effect; Bottom establishes strip air inlet, and when scavenger fan rotates, cooler air can from air inlet inspiration, and make air inlet area more extensively evenly, radiating effect is better; Housing, bottom and heat radiation grid adopt aluminum material, and heat-conductive characteristic is good.

Fig. 2 is enclosure interior schematic diagram of the present utility model.
Fig. 3 is bottom cover structure schematic diagram of the present utility model.
Fig. 4 is control principle schematic diagram of the present utility model.
In accompanying drawing: 1, housing, 2, control board, 3, scavenger fan, 4, heat radiation grid, 5, temperature sensor, 6, bottom, 7, air inlet.
Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is described further.
As shown in drawings, a kind of electric vehicle controller, comprise aluminum cuboid housing 1, aluminum bottom 6 and be arranged on the control board 2 of housing 1 inside, 4 scavenger fans 3 are established on described cuboid housing 1 top, and all the other each outer surfaces establish strip to dispel the heat grid 4; Housing 1 inner surface is fixed with temperature sensor 5; Described bottom 6 establishes 9 strip air inlets 7.
During the work of this electric vehicle controller, controller itself can produce heat, the temperature sensor 5 being arranged on aluminium casing 1 inner surface measures controller internal temperature, and temperature signal is transferred to control board 2, setting T1, T2, T3, T4 tetra-temperature spots from low to high successively in control board 2.When measuring temperature lower than T1, control board 2 controls 4 scavenger fans and does not rotate; When mensuration temperature is between T1 and T2, control board 2 controls 1 scavenger fan and rotates heat radiation; When mensuration temperature is between T2 and T3, control board 2 controls 2 scavenger fans and rotates heat radiation; When mensuration temperature is between T3 and T4, control board 2 controls 3 scavenger fans and rotates heat radiation; When measuring temperature higher than T4, control board 2 controls 4 scavenger fans and all rotates heat radiation.Rotate the number of heat radiation like this according to temperature distribution scavenger fan, the effective reasonable energy utilization of energy, avoids causing energy waste.
Housing 1 surrounded surface is provided with strip heat radiation grid 4, adds housing 1 surface and the contact area of outside air, can increase radiating effect; Bottom 6 establishes 9 strip air inlets 7, and when scavenger fan 3 rotates, cooler air can from air inlet 7 inspiration, and make air inlet area more extensively evenly, radiating effect is better; Housing 1, the bottom 6 of aluminum material and the grid 4 that dispel the heat, heat-conductive characteristic is good.
Claims (3)
