Description

Technical Field

[0001] The utility model relates to a water cooling structure, in particular to a water cooling structure of a motor, and belongs to the technical field of motor equipment manufacturing. Background Art

[0002] Motor water cooling is currently mainly achieved by designing the flow channels of the water-cooled motor casing. Considering the sealing of the connection, stir friction welding is usually used to seal the two ends of the casing so that the cooling medium only flows in the flow channels inside the casing. Water inlets and outlets are designed on the surface of the casing, and water is passed through the chiller to achieve water cooling effect on the motor.

[0003] Problems with existing technologies:

[0004] A. The flow path in the casing is designed to be short. For small motors, the casing is short, the cooling medium flow path is short, and the cooling effect is poor;

[0005] B. When the motor is used for a long time, the cooling medium will leave impurities in the flow channel. Over time, the cooling efficiency will become lower and lower, and even when blockage occurs, it will cause more serious problems. In addition, the manual cleaning process is cumbersome and requires disassembly of the motor, which is inefficient and increases labor costs. Summary of the Invention

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] A water cooling structure for a motor, wherein a flow channel is composed of a second water channel 4 arranged in a front cover 1 and a rear cover 2 and a first water channel 8 arranged in a shell connected in series.

[0027] The first water channel 8 is arranged along the length of the motor housing, and the plurality of first water channels 8 are parallel to each other. The second water channel 4 is arc-shaped, and two adjacent first water channels 8 are connected in series at their ends to form a water flow path.

[0028] The depth of the second water channel 4 is designed based on the combined thickness of the front and rear end covers 2. Preferably, the depth of the second water channel 4 in the front end cover 1 is 35 mm, and the depth of the second water channel 4 in the rear end cover 2 is 50 mm. While ensuring the strength of the front and rear end covers 2, a deeper groove depth is selected to extend the flow path and achieve better cooling effect.

[0029] The seal between the front and rear end covers 2 and the casing 3 is achieved by two O-rings, one inside and one outside. The inner O-ring prevents the cooling medium from entering the interior of the motor, and the outer O-ring prevents the cooling medium from leaking to the surface of the motor casing 3 and causing an accident.

[0030] A chute is provided in the second water channel 4 along the arc, and the slide rod 5 is placed in the second water channel 4 along the depth direction of the second water channel 4. A slider 9 matching the chute is fixed at the bottom of the slide rod 5; through the slider 9, the slide rod 5 can slide along the chute, that is, slide along the arc under the impact of the cooling medium.

[0031] The cross section of the slide bar 5 is semicircular, and the arc surface is away from the slide groove, that is, the slider 9 is provided with its bottom plane and slides through the bottom plane. Preferably, the slider 9 is provided in the middle position of the slide bar 5.

[0032] Preferably, the slide bars 5 are arranged in opposite directions in the front cover 1 and the rear cover 2. That is, when the slide groove in the front cover 1 is arranged along the bottom wall of the second water channel 4 therein, the slide groove in the rear cover 2 is arranged along the top wall of the second water channel 4 therein.

[0033] Scraping strips 10 are provided on both sides of the sliding bar 5 along the length direction of the sliding bar 5 .

[0034] Preferably, the water inlet 6 and the water outlet 7 are provided on the casing 3 .

[0035] When using,

[0036] When the chiller passes the cooling medium through the water inlet 6 on the casing 3, the cooling medium enters the flow channel. When it reaches the flow channel part on the front cover 1, the cooling medium will generate eddy currents on the curved surface when it hits the slide bar 5, thereby enhancing the movement ability of the cooling medium and thus improving the cooling efficiency.

[0037] At the same time, during the flow of the cooling medium, the sliding rod 5 will be pushed, so that the sliding rod 5 slides along the slide groove. When the sliding rod 5 moves, the impurities and sediments in the flow channel are scraped to a certain extent, thereby cleaning the impurities and sediments.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the scope of protection of the present invention.
