Installation structure of discrete IGBT of high-power electric automobile controller

The utility model discloses an installation structure of a discrete IGBT of a high-power electric automobile controller, and belongs to the technical field of discrete IGBT modules. The heat dissipation device comprises a heat dissipation base, a heat dissipation limiting plate, a heat dissipation contact plate, an IGBT module mounting plate, a discrete IGBT module, an elastic pressing strip and apressing screw, the heat dissipation base, the heat dissipation limiting plate and the IGBT module mounting plate are stacked up and down; a plurality of groups of heat dissipation contact plates arearranged; the heat dissipation contact plate is installed in the heat dissipation limiting plate and is flush with the heat dissipation limiting plate. A plurality of groups of discrete IGBT moduleswith the same structure are arranged; the discrete IGBT module is mounted in the IGBT module mounting plate; the elastic pressing strips are arranged at the tops of the two adjacent groups of sub-vertical IGBT modules in an abu
