Abstract

The invention relates to a liquid-cooled motor shell, which comprises an inner shell and an outer shell, wherein the outer shell sleeves the outside of the inner shell; the outer shell is provided with a water inlet and a water outlet; an inlet part runner convergence zone and an outlet part runner convergence zone are arranged at the positions, corresponding to the water inlet and the water outlet, of the inner shell respectively; a runner turning convergence zone is arranged on the inner shell for dispersing and converging a cooling liquid; multiple rows of isolating ribs are arranged on the inner shell for controlling the flow direction; sawtooth fins are arranged at two sides of the inlet part runner convergence zone, the outlet part runner convergence zone and the runner turning convergence zone and between the inner shell and the outer shell, and are arranged on the inner shell or the outer shell; and the sawtooth fins are multiple rows of individual fins. By the liquid-cooled motor shell, turbulent flow can be strengthened and the thermal resistance and a temperature rise of the motor shell are obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a liquid-cooled motor casing. Background technique [0002] In the development of the motor, the design of the cooling system is directly related to the temperature rise and performance of the permanent magnet motor, and needs to be paid attention to. With the increase of motor power, the temperature rise of the motor is getting higher and higher, and the requirements for the cooling system are also getting higher and higher. At the same time, in many cases, it is necessary to use hydraulic oil or the like as a cooling medium. Due to the high viscosity of the hydraulic oil, it is mostly laminar flow in the flow channel of the motor, the thickness of the boundary layer is very large, the convective heat transfer coefficient of the wall surface of the flow channel is small, and the thermal resistance is large, so the heat dissipation effect is very poor. Due to the large thermal r...
