Abstract
The invention discloses an air-cooled electric vehicle controller, which comprises a hollow shell, a turbo fan, a front gasket, a front baffle, a rear gasket, a rear baffle, a screw, spring, and eighteen power tubes welded to circuit board. The invention is characterized in that an outer surface of the hollow shell is distributed with striped heat radiating fins; each heat radiating fins is added with two rows of bumps; a bottom of the hollow shell is square; a heat dissipation boss is arranged on the middle side of the hollow shell; and the heat dissipation boss is provided with a convex rib for mounting the spring piece. The air-cooled electric vehicle controller has the advantage that the spring is assembled to the ribs of the heat radiating shell to deform to produce elastic force, the elastic force is applied to a power tube body through pins of the spring piece to ensure that a power tube is tightly fitted with an inner surface of the hollow shell, and a heat conduction path is shortest. At the same time, the turbo fan in time takes away the heat generated by the power tube to ensure timely and effective heat conduction.
Description
Technical field
The present invention relates to a kind of controller for electric vehicle, especially a kind of air-cooled controller for electric vehicle.
Background technology
With the development of society and being continuously increased for the fuel oil vehicles, the natural resourcess such as petroleum fuel that the mankind face are not
Foot and fuel emission cause the problem of global warming increasingly to highlight.So the friendship of hybrid power or pure power in this context
In all means of transport gradually enters into the life of people, and electric motor car arises at the historic moment.Controller is the core component of the electric motor car, it
Be by control motor electric current come ensure vehicle traveling needed for power, to ensure vehicle normally travel and safety have to
Close important effect.Controller for electric vehicle under prior art state mostly is power tube and is arranged in a row, by the switching of aluminum strip, Gu
It is scheduled on the side wall of hollow housing, controller one end has wire harness to export.Internal power tube is main heater element, it is necessary to
Other heat carrier laminating radiatings just can guarantee that the work of its normal continuous.During assembling by 18 power tubes on circuit board with lead
It is screwed after hot aluminum strip laminating, then is screwed after heat conduction aluminum strip is fitted with aluminium section bar radiation shell inner surface.Function
Front apron and backboard, rear sealing gasket are separately mounted to the two ends of aluminium section bar radiation shell by wire harness again through after front sealing gasket.Should
Often there is problems with when actually used in the controller of structure：
Power tube is single distribution, the heat undue concentration that power tube is produced during work, along with heat is passed through heat conduction aluminum strip
Lead oversize to thermally conductive pathways during aluminium section bar radiation shell, radiating effect is poor, Jing often because heat can not timely and effective derivation and cause
Power tube burns out failure, and controller function is lost.
Affected by thread quality on heat conduction aluminum strip, individual power pipe is fitted with coupling mechanism force during screw lock with heat conduction aluminum strip
Less or stripped thread, causes individual power pipe to be fitted bad, and power tubular heat can not be effectively conducted away and cause individual power to burn out
Failure, controller function is lost.
The content of the invention
It is to overcome the shortcomings of prior art that present invention offer is purpose, there is provided a kind of air-cooled controller for electric vehicle, the control
Device is to carry out air-cooled auxiliary heat dissipation from the basis of radiating original, to increase the heat dispersion of controller.Also in original
Radiating boss is increased on the basis of empty capsid and the convex tendon of spring leaf is installed, by the convex tendon that spring plate group is attached to radiation shell
On be allowed to deformation and produce elastic force, elastic force is applied on power tube body by the foot on spring leaf, with ensure power tube with it is hollow
Shell inner surface is brought into close contact, and heat conduction path is most short, meanwhile, turbofan in time takes away the heat that power tube is produced, and protects
The promptness and effectiveness of heat conduction are demonstrate,proved.
The present invention is achieved through the following technical solutions：A kind of air-cooled controller for electric vehicle, including hollow housing, turbine
Fan, front sealing gasket, front apron, rear sealing gasket, backboard, screw, spring leaf, welding 18 power on circuit boards
Pipe.It is characterized in that：The outer surface of hollow housing is distributed with strip radiation tooth, and two row's salient points have been added above each radiation tooth, in
Empty capsid bottom is square, and in the medial side face of hollow housing a radiating boss is provided with, and on radiating boss installation bullet is provided with
The convex tendon of reed,
Respectively there are four apertures on front apron and backboard, spring leaf carries 18 feet, and every foot one power tube of correspondence will
Power tube is pressed on the boss of hollow housing, and 18 power tubes for welding on circuit boards are directly fitted in scattered by spring leaf
On the boss of hot shell.Described front apron upper band screw hole, is connected by screw with external turbine fan.
The present invention has advantages below：Described power tube is directly fitted with the radiating boss surface in hollow housing, work(
Rate pipe produce heat can directly be conducted to hollow housing, make heat conduction path most short, it is ensured that heat conduction promptness and
Effectiveness, eliminating power tube causes the overheated hidden danger for burning out because conduction of heat is bad.Described front apron upper band screw hole, it is and outer
Portion's fan connection, reaches air-cooled effect.During electric motor car runs, the heat of power tube generation is taken away by turbofan
Amount, further ensures the promptness and effectiveness of heat conduction, and eliminating power tube causes overheated burning out because conduction of heat is bad
Hidden danger.
