Problems solved by technology

[0002] At present, permanent magnet synchronous motors with high power density and low-speed torque motors are generally cooled by water cooling. In the existing technology, many manufacturers mainly use equidistant spiral channels. Flow in one direction of rotation cannot form turbulent flow in the water channel, so the cooling effect is not very ideal, and the motor has a risk of failure

Embodiment Construction

[0019] see figure 1 , figure 2 and image 3 , the structural form of the equidistant ring form motor cooling channel in this embodiment is:

[0020] The cooling water channel is connected to a continuous water flow channel by the annular cavities equidistant and spaced along the axial direction. The cooling water inlet 1 and the cooling water outlet 4 of the water flow channel are located at the water inlet end ring and the cooling water outlet at the two ends. On the water outlet ring; each annular chamber is an open ring that can be flattened into a rectangle; adjacent annular chambers are connected end to end, and end to end connection means that the outlet of the adjacent previous annular chamber is connected with the entrance of the next annular chamber. In order to make the circumferential direction of the water flow formed in the adjacent annular cavity around the surface of the motor casing opposite.

[0021] In the specific implementation, the angle between the ax...

Abstract

The invention discloses an equal-interval ring type motor cooling water channel. The motor cooling water channel is characterized in that all ring-shaped cavities which are distributed at equal intervals along the axial direction are communicated to form a continuous water flow channel, a cooling water inlet and a cooling water outlet of the water flow channel are respectively formed in a water inlet end ring and a water outlet end ring at the two ends, each ring-shaped cavity is in the shape of an opened ring with a flat rectangular surface, the adjacent ring-shaped cavities are connected end to end, i.e., the outlet of one ring-shaped cavity is communicated with the inlet of the next ring-shaped cavity, so that the water flows in the adjacent ring-shaped cavities oppositely flow along the circumference of the surface of a motor casing. The heat exchange coefficient and the heat exchange rate of a cooling system can be effectively improved, the temperature rise of a motor is reduced and the reliability of the motor is enhanced.

Description

technical field [0001] The invention relates to a motor cooling water channel structure, in particular to a cooling water channel for a permanent magnet synchronous motor with high power density and a low-speed torque motor. Background technique [0002] At present, permanent magnet synchronous motors with high power density and low-speed torque motors are generally cooled by water cooling. In the existing technology, many manufacturers mainly use equidistant spiral channels. Flow in one direction of rotation cannot form turbulent flow in the water channel, so the cooling effect is not very ideal, and the motor has a risk of failure. Contents of the invention [0003] In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides a motor cooling channel in the form of an equidistant ring, in order to improve the heat transfer coefficient and heat transfer rate of the cooling system, reduce the temperature rise of the motor, and improve...
