Abstract

The invention relates to a motor cooling device, and discloses a water-cooling device for a motor. The water-cooling device for the motor comprises a base and sealing plates, wherein an outer ring of the base is arranged on the base; an internal cylinder of an engine base is arranged in the outer ring of the base; an annular space formed between the internal cylinder of the engine base and the outer ring of the base is welded through the sealing plates; adjacent water filling nozzle and water outlet are formed in the outer ring of the base; a plurality of water-cooling units are evenly distributed between the internal cylinder of the base and the outer ring of the base; each water-cooling unit comprises four outer ribs which are transversely arranged in sequence; the first outer ribs are welded on the sealing plate at the inner side; the second outer ribs and the fourth ribs are inlaid between the internal cylinder of the engine base and the outer ring of the base; the third outer ribs are welded on the sealing plate at the outer side; and the plurality of water-cooling units are sequentially arranged to form a cocurrent double-row water cooling structure. Due to double rows of circulating channels, one half of welding spots are reduced; and the water leakage risk can be effectively lowered by reduction of the welding spots. The motor is rusted or even damaged by leaking water, so that the service lifetime of the motor is prolonged.

Description

technical field [0001] The invention relates to the field of motor cooling, in particular to a motor water cooling device. Background technique [0002] At present, the cooling methods of the motor mainly include the following types: natural cooling, forced air cooling, self-ventilation, and water cooling. Compared with other cooling methods, at the same power level, the motor cooled by water cooling has the advantages of small size and light weight. , the material utilization rate is higher. [0003] At present, in the water-cooled motor industry, the structure of the general-purpose water-cooled welded machine base is that the inner cylinder of the machine base is rolled and welded with steel plates, the outer circumference of the inner cylinder is welded or the water channel is processed, the outer wall of the machine base is rolled or welded with steel plates, and the ends of the inner and outer cylinders are welded. The end plate is welded with the inner and outer cyli...
