Problems solved by technology

However, the existing integrated inverter has the following technical problems during use: the existing integrated inverter simply arranges the power module and the energy storage capacitor side by side on the same side of the radiator, and the power module and the energy storage capacitor occupy The installation space is large and the integration level is low, which still affects the overall volume of the motor to a certain extent
In addition, the radiator of the existing integrated inverter is only provided with a cooling water channel at the position of the power module, but it cannot cool and dissipate the heating elements such as the control board and the energy storage module, which affects the service life of the inverter

Abstract

A motor inverter disclosed by the invention comprises a shell, a radiator, a power module, an energy storage module, a control panel and a filtering module. The radiator is provided with a via hole, the radiator is provided with a cooling water channel at the outer side of the via hole, the power module is arranged at one side of the radiator, and the power module comprises three power boards. The three power boards are arranged on the outer side of the via hole in the circumferential direction and correspond to the cooling water channel in position, the filtering module and the power module are arranged on the radiator in an adjacent mode, the energy storage module is arranged on the other side of the radiator, and the energy storage module partially penetrates through the via hole to be electrically connected with the three power boards and the filtering module. The shell is connected with the radiator and covers the power module, the filtering module and the energy storage module, the control panel is arranged between the shell and the power module and fixedly connected with the radiator on the inner side of the cooling water channel, and the control panel is electrically connected with the power module, the filtering module and the energy storage module. The motor inverter is small in size, high in heat dissipation efficiency and long in service life.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor inverter. Background technique [0002] Motor inverter is a widely used power converter for vehicles. In recent years, integrated inverters have become more and more widely used. Integrated inverters integrate the inverter on the back cover of the motor, which can effectively save installation Space, reduce equipment size. However, the following technical problems exist in the use of the existing integrated inverter: the existing integrated inverter simply arranges the power module and the energy storage capacitor side by side on the same side of the radiator, and the power module and the energy storage capacitor occupy The installation space is large and the integration level is low, which still affects the overall volume of the motor to a certain extent. In addition, the radiator of the existing integrated inverter is only provided with a cooling water channel at the p...
