Description

Technical Field

[0001] The present invention relates to the technical field of motor heat dissipation, and in particular to a motor heat dissipation structure. Background Art

[0002] The structure of the motor generally includes a stator, a rotor and structural components, etc. The structural components include heat dissipation fan, etc. When current is passed through the coil and the motor is working continuously, heat will be generated. When the motor generates heat after running for a period of time, the heat needs to be processed. In existing motors, the heat is generally dissipated by using its own rotor to drive the fan to rotate, or by using air cooling or water cooling. These methods can dissipate the heat of the motor, but there are also problems.

[0003] Regarding water cooling, in the prior art, in order to prevent excessive temperature rise in various parts of the motor, special channels or pipes filled with water are usually provided in the hottest part of the motor. The circulating air inside the motor brings the internal heat to the surface cooled by the water, thereby achieving the purpose of water cooling.

[0004] Since water cooling cannot be effectively adjusted according to the heat generated by the motor, when the motor works for a short time and the heat generated by the motor is low, the water cooling condition can meet the heat dissipation of the motor; however, when the motor works for a long time, resulting in higher heat generated by the motor, since the water cooling condition cannot be adjusted, the stable water cooling condition cannot meet the heat dissipation of the motor; this will result in some heat not being effectively absorbed.

[0063] like Figure 2 and Figure 6 As shown, a motor heat dissipation structure is provided, wherein semiconductor cooling sheets 15 are installed on the inner walls around the upper part of the water tank 801. When the semiconductor cooling sheets 15 are powered on, the temperature can be lowered (this is the prior art). The semiconductor cooling sheets 15 are used to lower the temperature of the upper water.

[0064] Working principle: When water enters the water tank 801 through the output pipe 804, the water in the output pipe 804 passes through the air chamber 7, and the water temperature rises when entering the water tank 801 due to the transfer effect, that is, the water temperature entering the water tank 801 is relatively high; when the water enters the upper part of the water tank 801, the funnel 12 can insulate the water in the upper part, and the water flow continues to accumulate, and the inflator 1301 is started, so that the inflator 1301 inflates the connecting pipe 1302, and the gas is sprayed on the branch pipe 1303 and the air nozzle 1304. Under water, the water in the upper part will be stirred, which will speed up the discharge of heat through the heat dissipation holes 8011 and improve the heat dissipation capacity of the water.

Since the butterfly plate 1401 is connected to the funnel 12 by rotation, the butterfly plate 1401 will rotate, so that a gap is formed between the butterfly plate 1401 and the funnel 12. At this time, the water with reduced temperature will flow into the lower part of the water tank 801 from the gap; when the pressure sensing sheet 1402 senses that the water pressure decreases to a certain value, the processor 901 collects a small water pressure data, so that the processor 901 controls the two electric push rods 1403 to move to the original position, so that the butterfly plate 1401 moves It moves to its original position, forming a seal with the funnel 12.

At the same time, the semiconductor refrigeration sheet 15 and the stirring mechanism 13 are used to process the warm water to accelerate the heat dissipation of the water and reduce the temperature of the water in the upper part. At the same time, after the water temperature drops, the flow limiting mechanism 14 can release the water in the upper part, so that it flows into the lower part.
