Heat dissipation water channel of new energy motor controller

Abstract

The invention discloses a heat dissipation water channel of a new energy motor controller, relates to the technical field of electric vehicle driving motor assemblies, and aims to solve the problems that a cooling liquid in an existing heat dissipassion device cannot fully absorb heat of the heat dissipassion device, the inlet and outlet temperature difference is large, the heat dissipation effectis poor, the temperature of an IGBT module is too high, and long-time stable work of the motor controller is not facilitated. According to the scheme, the heat dissipation water channel comprises a heat dissipassion device body, wherein a heat dissipation water channel main body is arranged in the heat dissipassion device body; two sets of flow guide blocks are arranged in the heat dissipation water channel main body; BOSS bosses are arranged on the two sides of each flow guide block; a plurality of heat dissipation ribs are arranged on the sides, close to each other, of the two sets of flowguide blocks; four water channel partition plates are arranged among the plurality of radiating ribs; and a plurality of second inner wall spoiler blocks are arranged on the water channel partition plates. According to the heat dissipation water channel of the new energy motor controller, the heat dissipation effect is improved, heat dissipation is more balanced, and the motor controller can stably work for a long time at a comfortable temperature.

Description

technical field [0001] The invention relates to the technical field of electric vehicle drive motor assembly, in particular to a heat dissipation water channel for a new energy motor controller. Background technique [0002] The existing new energy motor controller includes a radiator and a power module. The module that mainly needs heat dissipation is the IGBT module. There is a cooling water channel in the radiator. The power (power is replaced by IGBT) module is installed next to the cooling channel of the radiator. Both ends of the cooling water channel are provided with water inlets and water outlets, and a number of diversion blocks and spoiler blocks are arranged in the cooling water channel to play the role of guiding and disturbing the flowing water channel in the water channel. However, the coolant in the existing radiator cannot fully absorb the heat of the radiator, and the temperature difference between the inlet and outlet (plus the wafer) is large, and the hea...
