Abstract

The invention discloses a load controller and an electromobile with the load controller. The load controller comprises a casing, a busbar module, a capacitor, an IGBT power module, a heat radiation module, a driving circuit board and a control circuit board; the busbar module comprises a DC busbar and an AC busbar connected to a load; the capacitor is connected with an external DC power supply andthe DC busbar; the input end of each IGBT is connected with the DC busbar, and the output end of each IGBT is connected with the AC busbar; the heat radiation module comprises radiating fins, each IGBT in the same column is clamped between two adjacent radiating fins; the driving circuit board is electrically connected with each IGBT; the control circuit board is connected with the driving circuit board; and the busbar module, the IGBT power module, the heat radiation module, the driving circuit board and the control circuit board are mounted on the casing; According to the load controller ofthe invention, the heat radiation efficiency is high, the heat radiation effect is good, and the size is small.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a load controller and an electric vehicle with the load controller. Background technique [0002] In the related art, in the load controller of the electric vehicle, the heat sink and the power module (such as the IGBT power module) are in single-sided contact for heat dissipation, and the heat dissipation efficiency is low, and the layout of the busbar, the power module and the heat sink in the load controller box Unreasonable, takes up a lot of space, has a large volume, and there is room for improvement. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the first aspect of the present invention proposes a load controller with small volume and high heat dissipation efficiency. [0004] A second aspect of the present invention proposes an electric vehicle having the...
