Arrangement structure of main electrical components inside bidirectional charger for electric vehicle

The invention discloses an arrangement structure of main electrical components inside a bidirectional charger for an electric vehicle. The main electrical components include a radiator, a control circuit module, a power component IGBT (insulated gate bipolar transistor) and a magnetic component. The arrangement structure takes a middle clapboard as the boundary to divide a box body of the bidirectional charger into upper and lower cavities, wherein the box body and the middle clapboard are welded together; a hole is dug in the middle clapboard, and the radiator is plunged into the hole, so that a substrate of the radiator is in the upper cavity and a fin thereof is in the lower cavity; a sealing strip is pasted between the hole on the middle clapboard and the radiator; the upper cavity of the box body is divided into two layers; the control circuit module is arranged on the upper layer; the power component IGBT is arranged on the lower layer; the magnetic component is installed in the lower cavity of the box
