Embodiment Construction

[0032] The invention will be described in detail below in conjunction with the drawings.

[0033] Such as figure 1 with 2 As shown, a liquid-cooled cycle power device includes an electric vehicle body with a shock absorber. It also includes a hydraulic cylinder 80. The hydraulic cylinder 80 and the piston 81 are slidably sealed so that the piston 81 can slide axially along the hydraulic cylinder 80. A mandrel is fixed on one side of the piston 81. The mandrel extends out of the hydraulic cylinder 80 and is hinged with the car body. The axis of the hydraulic cylinder 80 is parallel to the axis of the shock absorber of the vehicle, and the hydraulic cylinder 80 is fixed on the rear axle or the rear axle of the vehicle.

[0034] The bottom end of the hydraulic cylinder 80 communicates with the liquid inlet of the impeller assembly 60 through a pipe with a first check valve 82, so that the liquid in the hydraulic cylinder can enter the impeller assembly 60 and drive the impeller 61 to ...

Abstract

The invention discloses a liquid-cooling cycle power device and a liquid cooling controller with the same. The liquid-cooling cycle power device comprises an electric vehicle body with a damping device and further comprises a hydraulic cylinder, wherein the hydraulic cylinder is in sliding and sealing fit with a piston, so that the piston can slide along the axial direction of the hydraulic cylinder. An ejector rod is fixed on one side of the piston, the ejector rod extends out of the hydraulic cylinder and is hinged to the vehicle body, the axis of the hydraulic cylinder is parallel to the axis of a damper of a vehicle, and the hydraulic cylinder is fixed on a rear axle shaft or a rear axle of the vehicle. The bottom of the hydraulic cylinder is communicated with a liquid inlet of an impeller assembly through a pipeline with a first one-way valve, so that liquid in the hydraulic cylinder can enter the impeller assembly and drive an impeller to rotate. A liquid outlet of the impeller assembly is communicated with a temporary liquid storage tank through a pipeline, and the temporary liquid storage tank is communicated with the middle and upper part of the hydraulic cylinder througha pipeline with a second one-way valve. The liquid-cooling cycle power device can convert vibration of the vehicle body to generate rotary power, so that a cycle of liquid is achieved and electric energy consumption is reduced.

Description

Technical field [0001] The invention relates to a cooling device of a motor controller, in particular to a liquid cooling device of a motor controller. Background technique [0002] Electric motors are used more and more frequently in electric vehicles, especially in the context of the continuous popularity of new energy vehicles, and the requirements for motor control continue to increase. Vehicle safety is one of the core indicators of a motor vehicle. The controller must work within a safe temperature. One is to ensure that the components are normal, and the other is to increase the service life. Therefore, liquid cooling is one of the alternatives for the controller to maintain a good operating temperature. [0003] Generally, liquid-cooled liquid circulation requires additional power to drive the liquid to circulate in the liquid storage device of the circulating pipeline. For electric vehicles, power consumption is directly related to the cruising range, and the additional p...
