Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to a motor with high efficiency, heat dissipation and energy saving. Background Art

[0002] In the actual operation and application of motors, solving the heat dissipation problem of motors has always been a key task and an important way to improve the efficiency and effectiveness of motor operation. The heat dissipation methods of heat dissipation motors mainly include air cooling, liquid cooling and evaporative cooling. Air cooling is the most common cooling method, which uses flowing air to cool the motor and is suitable for small power motors. Liquid cooling has higher heat dissipation efficiency and is suitable for motors with high heat generation and high heat flux density.

[0003] However, when the motor is currently being improved with liquid cooling, the overall structure of the motor needs to be greatly modified to adapt to the layout and installation of the liquid cooling system. Therefore, it is necessary to design a technical solution that can achieve liquid cooling of the motor without changing the motor body as much as possible, and can also adjust its heat dissipation effect. Summary of the invention

The first pipeline has a starting end connected to the pump assembly and a stopping end connected to the radiator. The second pipeline has a starting end connected to the radiator and a stopping end connected to the pump assembly. The first pipeline is arranged around the stator of the motor body.

[0008] For the pump assembly, the following embodiment is provided:

[0010] The pump housing assembly comprises a hollow disc-shaped pump housing body, a central diaphragm arranged in the middle of the pump housing body, the pump housing body is provided with a left operating chamber and a right sealing chamber respectively on the left and right sides of the central diaphragm, the right lower right side of the right sealing chamber is provided with a first one-way valve passing through the lower valve hole and connected to the start end of the first pipeline, the right upper right side of the right sealing chamber is provided with a second one-way valve passing through the upper valve hole and connected to the end end of the second pipeline, the left side of the pump housing body is also provided with a left housing connected with the left operating chamber, the inner wall of the left housing is provided with a guide slot along the left and right directions, and the left side of the inner wall of the left housing is also provided with a limiting convex ring;

[0011] The retraction assembly is arranged on the right side of the left housing to drive the middle diaphragm to automatically return to the left;

[0012] The reciprocating assembly is arranged on the left side of the left-mounted housing and reciprocates in the left-right direction. When the reciprocating assembly moves to the right, it drives the retraction assembly and the middle diaphragm to move to the right.

[0013] As a further implementation:

It has a high degree of structural integration and requires very little structural improvement to the motor body. It only requires reserving a certain space between the stator of the motor body and the outer casing of the motor body to arrange the first pipeline and the second pipeline. The entire liquid cooling assembly can be directly installed on the left side of the motor body.

[0018] The case describes a high-efficiency heat dissipation and energy-saving motor, in which the pump assembly pumps the cooling medium in the liquid supply pipeline, so that the cooling medium effectively circulates in the circulation path of the first pipeline, the radiator, the second pipeline, and the pump assembly, thereby achieving rapid and effective heat dissipation and cooling.

[0019] The high-efficiency heat dissipation and energy-saving motor described in this case can also adjust the right limit position of the central diaphragm of the pump assembly in a single reciprocating motion, thereby adjusting the pumping efficiency of the pump assembly and further adjusting the final heat dissipation effect.

[0058] Based on the energy-saving motor with high efficiency heat dissipation, the steps of heat dissipation through the liquid cooling assembly 8 are as follows:

[0061] Shift right phase:

[0062] When the driven slide 231 is at the left limit position, the retraction compression spring 226 is relaxed so that the retraction assembly 22 moves to the left limit position (i.e., the sealing clamp 227 abuts against the left wall of the pump housing body 211), and at this time, the reciprocating assembly 23 is out of contact with the retraction assembly 22;

[0063] The driven slide 231 moves rightward to the right limit position, the driven slide 231 approaches and abuts against the retracting assembly 22, and then further squeezes the retracting assembly 22 to overcome the damping of the retracting compression spring 226 and move rightward;

[0064] Shift left phase:

[0065] The driven slide 231 moves to the left, and the retraction assembly 22 is also reset to the left limit position (i.e., the sealing clamping plate 227 abuts against the left wall of the pump housing body 211) under the action of the retraction compression spring 226;

[0066] The driven slide 231 continues to move leftward and disengages from the retracting assembly 22 until the driven slide 231 moves to the left limit position.

[0071] Based on the above-mentioned regulating assembly 4, a method for regulating the pumping efficiency of the pump assembly 2 is also disclosed:

[0072] See the instruction manual Figure 6 , 7 , as shown in 8,

[0073] Step 1:

[0074] Use a slender tool (such as a screwdriver) to insert into the driven slide cylinder 231 through the fixed inner tube 237, and press the transmission core shaft 411 to the right to make it move to the right to overcome the damping of the adjustment compression spring 414, and drive the sliding lock plate 413 to move to the right to release the transmission connection with the fixed lock plate 404;

[0075] Step 2:

[0076] Rotate the slender tool and drive the transmission core shaft 411 and the transmission key hole 412 to rotate, drive the transmission key 410 and the internal threaded tube 408 to rotate, and then drive the driven screw 407 and the adjustment terminal 405 to move to the right, and finally realize the position movement of the adjustment terminal 405, adjust the right limit position of the adjustment terminal 405 when the reciprocating assembly 23 moves to the right limit position, and finally adjust the right limit position of the retraction assembly 22 and the middle diaphragm 212, and adjust the liquid flow pumped by the middle diaphragm 212 of the pump assembly during a reciprocating movement to realize the adjustment of the pumping efficiency.
