Abstract
The utility model discloses a double-row power tube electric-vehicle controller which is composed of a plastic shroud, a sealing strip, bolts, a pressure plate, a rubber strip, eighteen power tubes welded on a circuit board, two functional plugs welded on the circuit board and a cast aluminium heat radiation shell. The utility model is characterized in that the controller is an up-down structured double-row power tube electric-vehicle controller; the upper part is the plastic shroud; the lower part is the cast aluminium heat radiation shell; the sealing strip is arranged between the plastic shroud and the cast aluminium heat radiation shell; and the eighteen power tubes welded on a circuit board and the two functional plugs which are welded on the circuit board are contained inside the controller. The controller has advantages as follows: as the eighteen power tubes welded on the circuit board are compacted through the pressure plate and the rubber strip by the use of the bolts to be tightly adhered to the plane of the cast aluminium heat radiation shell directly for heat radiation, the thermal conduction path is shortest, and timeliness and effectiveness of thermal conduction are guaranteed; and as the plastic shroud compacts the sealing strip and is then in snap joint with the cast aluminium heat radiation shell, sealing performance of the controller is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of controller for electric vehicle, especially a kind of double power tube controller for electric vehicle.
Background technology
Along with the continuous increase of social development and the fuel oil vehicles, the natural resourcess such as petroleum fuel that the mankind face are not enough and fuel emission causes the problem of global warming day by day to highlight.This just forces people to have to study a kind of pure electronic vehicles that oil is fuel of not take, and under this background, electric motor car has just arisen at the historic moment.Controller is the core component of described electric motor car, and it is that electric current by controlling motor guarantees the power that Vehicle Driving Cycle is required, to guarantee vehicle normally travelling and safety has vital effect.Controller for electric vehicle under the prior art state mostly is Aluminum Hollow section bar heat dissipation shell structure, and profile is rectangular shape, and an end has wire harness output.18 inner power tubes are main heater elements, must with other its normal lasting work of heat carrier laminating heat radiation guarantee.To after 18 power tubes on circuit board and the laminating of heat conduction aluminum strip, be screwed during assembling, then be screwed after will the heat conduction aluminum strip fitting with aluminium section bar radiation shell inner surface.The function wire harness is through front apron and backboard, rear sealing gasket being arranged on respectively to the two ends of aluminium section bar radiation shell after front sealing gasket again.The controller of this structure often there will be following problem when reality is used: the one, and forward and backward cover plate sealing property is bad, often can occur that in housing, water inlet causes the internal circuit short circuit because of drench with rain, surface gathered water splash etc.Two is that 18 power tubes are single distribution, the heat undue concentration that during work, power tube produces, add heat while conducting to the aluminium section bar radiation shell through the heat conduction aluminum strip thermally conductive pathways oversize, radiating effect is poor, often, because heat can not timely and effective derivation and cause power tube to burn out inefficacy, controller function is lost.The 3rd, be subject to the impact of thread quality on the heat conduction aluminum strip, indivedual power tubes are the less or stripped thread of coupling mechanism force during with heat conduction aluminum strip laminating use screw lock, cause indivedual power tube laminatings bad, the power tube heat can not effectively conduct and cause that indivedual power burns out inefficacy, and controller function is lost.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, and a kind of double power tube controller for electric vehicle is provided, and this controller is compression joint type, and good seal, thermally conductive pathways are the shortest, the power tube laminating is reliable and the good controller of heat dispersion.
The utility model is achieved by the following technical solution: a kind of double power tube controller for electric vehicle comprises plastics cover cap, sealing strip, screw, pressing plate, rubber strip, is welded on 18 power tubes on circuit board, is welded on two groups of function plugs, cast aluminium radiation shell on circuit board.It is characterized in that: the double power tube controller for electric vehicle that controller is up-down structure, the above is the plastics cover cap, it is below the cast aluminium radiation shell, be provided with sealing strip in the middle of plastics cover cap and cast aluminium radiation shell, inside is inclusive with 18 power tubes and the two groups of function plugs that are welded on circuit board, screw is assemblied on the cast aluminium radiation shell through pressing plate and rubber strip, is provided with the groove of placing sealing strip at cast aluminium radiation shell top edge, and the surface distributed outside the cast aluminium radiation shell has the strip radiation tooth.In plastics cover cap circumferential distribution, have six buckles corresponding with the card contact on the cast aluminium radiation shell respectively, cover surface at plastic jacket and be provided with two jack shell, the position of jack shell respectively be welded on circuit board on two groups of function plugs corresponding; 18 power tubes that are welded on circuit board divide two rows to be evenly distributed on the both sides of circuit board; Power tube and cast aluminium radiation shell inner surface are directly fitted and are compressed power tube with screw by pressing plate and rubber strip; Described pressing plate is the iron plate punch forming, and profile is U-shaped.
Owing to adopting technique scheme, the beneficial effects of the utility model are: after plastics cover cap press seal bar, six buckles of its circumferential distribution respectively with the cast aluminium radiation shell on the card contact clamping, can effectively guarantee the sealing property of controller, and the consistency of sealing is better; Be welded on 18 both sides that power tube divides two rows to be evenly distributed on circuit board on circuit board, avoided power tube zone heat undue concentration, eliminated power tube and concentrated and cause the overheated hidden danger burnt out because of heat.Power tube and cast aluminium radiation shell inner surface are directly fitted and are compressed power tube with screw by pressing plate and rubber strip, the heat that power tube produces can directly conduct to the cast aluminium radiation shell, make heat conduction path the shortest, guaranteed promptness and the validity of heat conduction, eliminated power tube and caused the overheated hidden danger burnt out because the heat conduction is bad.
