Title:
ELECTRIC MOTOR INVERTER
Document Type and Number:
WIPO Patent Application WO/2023/274349
Kind Code:
A1
Abstract:
Disclosed in the present application is an electric motor inverter, comprising: a housing, a radiator, a power module, an energy storage module, a control board and a filter module, wherein the radiator is provided with a through hole, and the radiator is provided with a cooling water channel on an outer side of the through hole; the power module is arranged on one side of the radiator; the power module comprises three power boards, which are circumferentially arranged on the outer side of the through hole and respectively correspond to the cooling water channel in position; the filter module and the power module are arranged on the radiator and are adjacent to each other; the energy storage module is arranged on the other side of the radiator, and the energy storage module partially passes through the through hole and is then electrically connected to the three power boards and the filter module; the housing is connected to the radiator and covers the power module, the filter module and the energy storage module; the control board is arranged between the housing and the power module and is fixedly connected to the radiator on an inner side of the cooling water channel; and the control board is electrically connected to the power module, the filter module and the energy storage module. The electric motor inverter has the beneficial effects of a small size, a high heat dissipation efficiency and a long service life.
