Cooling loop structure of water-cooled motor shell

The utility model discloses a cooling loop structure of a water-cooled motor casing, and belongs to the technical field of casing casting. The cooling loop is of a cylindrical structure and comprises a plurality of U-shaped water channels, the U-shaped water channels are sequentially communicated through arc-shaped water channels to form a one-way loop, and a plurality of corners are formed between the U-shaped water channels and the arc-shaped water channels. The cooling water channel is composed of a plurality of U-shaped water channels, the length of a cooling loop is increased, the heat exchange area of cooling water is increased, a plurality of corners are formed in the cooling water channel, water flow can form turbulent flow at the corners, flowing of the cooling water in the water channel is accelerated, and therefore the heat dissipation effect is improved. 本实用新型公开了一种水冷电机壳冷却回路结构，属于铸造机壳技术领域。本实用新型冷却回路呈圆柱状结构，包括若干个U型水道，U型水道之间依次采用弧形水道连通成一个单向回路，U型水道与弧形水道之间形成多个拐角。本实用新型的冷却水道由多个U型水道组成，增加了冷却回路的长度，从而增大了冷却水的换热面积
