Description
Technical field
This utility model relates to a kind of controller for electric vehicle, especially a kind of 3KW controller for electric vehicle.
Background technology
Along with development and being continuously increased of the fuel oil vehicles of society, the natural resources such as the petroleum fuel faced by the mankind is not enough and fuel emission causes the problem of global warming day by day to highlight.So the traffic of hybrid power or pure power means of transport altogether gradually enters into the life of people in this context, electric motor car arises at the historic moment.Wherein electro-tricycle is with its simple driver behavior, traffic safety and riding comfort, and environmental protection is pollution-free, is increasingly becoming and picks child, and the main force's car ridden instead of walk old age.Controller is the core component of described electric motor car, and it is to ensure the power needed for vehicle traveling by the electric current of control motor, to ensureing that the normal of vehicle travels and have vital effect safely.Controller for electric vehicle under prior art state mostly is power tube and is arranged in a row, and by the switching of aluminum strip, is fixed on the sidewall of hollow housing, and controller one end has wire harness to export.Internal power tube is main heater element, it is necessary to the work of other heat carrier laminating heat radiation its normal continuous of guarantee.It is screwed after the power tube on circuit board being fitted with heat conduction aluminum strip during assembling, then heat conduction aluminum strip is screwed after the laminating of aluminium section bar radiation shell inner surface.Front apron and backboard, rear sealing gasket are separately mounted to the two ends of aluminium section bar radiation shell by function wire harness again after passing front sealing gasket.If but the controller of this structure is assemblied on electro-tricycle, often occur the problem that when actually used
Electro-tricycle is much larger from anharmonic ratio two wheeler, and speed is fast, duty factor is bigger, and power tube is single distribution in the controller of this kind of structure, the heat undue concentration that during work, power tube produces, adding heat, to be conducted to aluminium section bar radiation shell thermally conductive pathways through heat conduction aluminum strip oversize, radiating effect is poor, if accomplish with electric four-wheel vehicle used by motor match 4KW time, often as heat can not timely and effective derivation and cause power tube to burn out inefficacy, controller function is lost.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, it is provided that a kind of 3KW controller for electric vehicle, this kind of controller for electric vehicle has been saved cost and easy to assembly, drastically increased packaging efficiency；Eliminate power tube and cause the overheated hidden danger burnt out because heat can not conduct in time, also eliminate power tube because of heat concentrate cause the overheated hidden danger burnt out.
This utility model is achieved by the following technical solution: a kind of 3KW controller for electric vehicle, including screw, plastics cover cap, sealing gasket, function plug, pcb board I, support column, pcb board II, aluminium base, radiation shell, sealing-plug, big binding post, electric capacity and 18 power tubes being welded on aluminium base.It is characterized in that: radiation shell is die casting hollow structure, there is strip radiation tooth border, there are three screwed holes radiation shell bottom, it is plastic cover plate at radiation shell top, it is provided with sealing gasket in the middle of plastic cover plate and radiation shell, internal equipped with pcb board I, pcb board II and one piece of aluminium base, aluminium base sets 18 power tubes and three support columns that welding fastens, aluminium base is locked in bottom radiation shell by screw, it is internally threaded at support column, by screw interlocking, aluminium base and pcb board I is linked together；Be arranged above with electric capacity, big binding post at pcb board II and double mould high contact pin, double moulding high contact pin other end and be welded on pcb board I, pcb board II is provided with function plug, function plug and and plastic cover plate between be provided with a spigot seal pad.Heat-conducting silicone grease is coated bottom described aluminium base.
Described sealing-plug is enclosed within the big binding post exposed.
Described described welding 18 power tubes on circuit boards divide two rows to be distributed on aluminium base.
Described big binding post one end with stud, by nut by big binding post together with pcb board II interlocking, to reduce contact impedance.
Described radiation shell is outside to be used for and motor connection, and inside is connected with aluminium base.
This utility model has the advantage that described radiation shell is die casting aluminium molding, coordinates plastics cover screw to assemble, saved cost and easy to assembly, drastically increased packaging efficiency during use；
18 described power tubes are directly welded on aluminium base, it is to avoid fit between power tube and heat conduction aluminum strip the conduction of heat the tightliest caused not in time, eliminate power tube and cause the overheated hidden danger burnt out because heat can not conduct in time.
Described welding 18 power tubes on circuit boards divide two rows to be distributed on aluminium base, it is to avoid power tube region heat undue concentration, eliminate power tube and concentrate because of heat and cause the overheated hidden danger burnt out.
