Description

Technical Field

[0001] The invention relates to the technical field of water-cooled motors, in particular to a double-layer water channel of a water-cooled motor with enhanced heat exchange efficiency. Background Art

[0002] A water-cooled motor is a motor that uses a water cooling system to dissipate heat. Compared with traditional air-cooled motors, water-cooled motors effectively reduce the temperature of the motor through a water cooling system, providing higher power density and better heat dissipation. Water-cooled motors are widely used in high temperature environments and variable frequency speed regulation systems due to their low noise and good cooling effects. Most small and medium-sized water-cooled motors are cooled by external water cooling, so the design of the water channel has become a key technology for the motor's heat dissipation capacity.

[0003] However, most of the traditional water-cooled motor water channels on the market adopt a single-layer water channel design, which is either spiral or circuitous. Since the single-layer water channel design only has solid-liquid-solid-air exchange channels, the water channel flow state is single, and the water flow inside the channel is easy to form laminar flow, reducing the heat exchange efficiency. In addition, during the long-term operation of the water channel, due to some particulate impurities and minerals contained in the cooling water, a layer of scale will gradually adhere to the inner wall of the water channel. When the scale accumulates too much, it will reduce the circulation surface of the cooling water and cause blockage, thereby affecting the working efficiency and life of the equipment.
