Problems solved by technology

In general, the drive controller and DCDC structure are independently designed, and their internal layout and cooling methods only need to meet their respective performance requirements. This design method is simple and convenient for maintenance and testing, but it takes up a lot of space and weighs a lot. , material cost is also higher
In the prior art, there is also a technical solution of connecting the drive controller and the DC con

Abstract

The invention provides an integrated structure of a drive controller and a direct current converter. The integrated structure comprises a drive controller shell, an upper cover plate, a direct current converter shell and a lower cover plate, wherein the direct current converter shell is fastened with the drive controller shell in a vertical direction, the bottom wall of the drive controller shell is provided with an upper surface and a lower surface, the upper surface is provided with a first grooved water channel which is provided with a water inlet and a backwater inlet, the first water channel is covered with a heating module in the drive controller, the lower surface is provided with a second grooved water channel, the second water channel is covered with the direct current converter shell, the water inlet and backwater inlet of the first water channel are communicated with the second water channel to enable all or part of the cooling liquid flowing in the second water channel to enter into the first water channel through the water inlet and flow back into the second water channel through the backwater inlet. The integrated structure of the driving controller and the direct current converter has the advantages of higher integration level and better cooling effect.

Description

technical field [0001] The invention relates to the field of automobile electrics. Background technique [0002] At present, with the intensification of global pollution, the reduction of carbon dioxide emissions has become a hot spot, and new energy vehicles have become a new trend in the automotive industry. Among new energy vehicles, electric vehicles are favored by consumers because of their energy saving, environmental protection, low consumption, and good operability. [0003] The electric drive system provides power and control for electric vehicles, in which the drive controller and DC converter (DCDC), as the core components of the drive system control, play a key role in the electric vehicle control system. The drive controller mainly drives and controls the operation of the motor, and the DC converter mainly provides electric energy for the low-voltage electrical equipment of the vehicle and charges the auxiliary power supply. Their structural design must not on...
