For reaching this object, the utility model by the following technical solutions:
A kind of controller for electric vehicle fixes the heat abstractor of metal-oxide-semiconductor, it comprises the shell body of hollow structure, and be provided with circuit board in described shell body, the side of described circuit board is connected with several metal-oxide-semiconductors be arranged side by side by pin, wherein, the madial wall of described shell body is outward extended with protruding mounting plane, coordinate whole row's metal-oxide-semiconductor to be provided with the fixing profile of strip, described fixing profile is installed on the one side of metal-oxide-semiconductor and is connected on described mounting plane by metal-oxide-semiconductor another side by coupling assembling.
Especially, described mounting plane and described metal-oxide-semiconductor are provided with dielectric film, and described metal-oxide-semiconductor is close to described dielectric film and is arranged.
Especially, described fixing profile cross section is " L " type structure, and the inner edge of described fixing profile bending part is arc-shaped structure, so that be close to the radian above metal-oxide-semiconductor.
Especially, described coupling assembling comprises correspondence and is opened in several screwed holes on described fixing profile and shell body sidewall and attachment screw, the screwed hole of described attachment screw on shell body sidewall is screwed into the screwed hole on fixing profile, fixing profile is shunk inside, thus metal-oxide-semiconductor is close on mounting plane.
Especially, described fixing profile is made up of galvanized iron sheet.
Especially, described shell body is outside equipped with fin.
Especially, two madial walls of described shell body are provided with draw-in groove in the below correspondence of described mounting plane, and described circuit board inserts in the draw-in groove on two madial walls, to be installed in described shell body.
The beneficial effects of the utility model are, the heat abstractor that compared with prior art described controller for electric vehicle fixes metal-oxide-semiconductor has the following advantages:
1) mode that traditional aluminum strip joins holding screw makes metal-oxide-semiconductor be fixed on the sidewall of controller housing to adopt fixing profile mode to replace, such mode simplifies installation procedure, also reduce production cost simultaneously, save controller housing inner space, the shell wall thickness thickeied decreases thermal resistance, serve the excellent effect of heat radiation, improve the reliability of controller for electric vehicle.
2) screw is avoided directly to contact with metal-oxide-semiconductor, thus reduce the electric leakage effect of controller, fix the heat abstractor of metal-oxide-semiconductor additionally by this mode, make to be connected between metal-oxide-semiconductor with shell tightr, thus heat can be distributed faster, therefore can greatly reduce metal-oxide-semiconductor spoilage.
