Description

Technical Field

[0001] The invention relates to the technical field of motor cooling, in particular to a motor with a linked water cooling mechanism. Background Art

[0002] When the motor is running at high speed, the efficiency will gradually decrease from about 90% to 80%. Even at the highest speed, the efficiency is less than 70%. The remaining 30% will be converted into heat energy. If this extra heat cannot be discharged smoothly, it will cause the permanent magnet of the permanent magnet motor to demagnetize, and the weakening of magnetism will cause irreversible damage and performance will decrease. More seriously, it will reduce the insulation of the motor stator winding, and in extreme cases, it will even burn the entire motor.

[0003] In order to protect the motor and avoid greater safety hazards, the temperature emitted by the motor needs to be dissipated outwards. The traditional motor heat dissipation method is mainly through passive heat dissipation through the copper sheet on its surface, or driven by other heat dissipation mechanisms connected to the motor shaft. The traditional active heat dissipation mechanism consumes a lot of motor kinetic energy and has relatively large friction. At the same time, some mechanisms with water cooling devices have very high requirements for sealing. It is necessary to directly use the motor shaft to drive the water cooling device. Long-term high-speed rotation also causes great wear and tear on the seals, which need to be replaced regularly, with high later costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved motor with a linked water cooling mechanism is provided to solve the problem that the active heat dissipation mechanism of the traditional motor needs to consume a large amount of motor kinetic energy and the friction force is also relatively large; the sealing requirements are very high, the seals need to be replaced regularly, and the later costs are high.

DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4 A motor with a linked water cooling mechanism is shown, comprising a motor body 1 and an external cover shell 2 installed on the outside of the motor body 1, the top of the external cover shell 2 has an upwardly protruding integrated top heat dissipation water tank 3, the right side surface of the external cover shell 2 is located on the periphery of the right side rotating shaft of the motor body 1 and is fixedly equipped with a rightward protruding annular drainage cover 4, an annular external transmission box 6 is fixedly equipped on the outer side surface of the annular drainage cover 4 through a lateral fixing box 5, a serpentine first heat conduction channel 7 and a serpentine second heat conduction channel 8 are symmetrically opened inside the outer wall of the external cover shell 2, and a magnetically coupled hydraulic drive device is installed inside the annular drainage cover 4, the lateral fixing box 5 and the annular external transmission box 6.

[0031] When 16 second permanent magnets 14 are used, 10 metal iron blocks are required to cooperate with 4 first permanent magnets 11. The transmission ratio at this time is 4:1, and the calculation method is that the number of input second permanent magnets 14 plus the number of output first permanent magnets 11 divided by 2 equals 10; when an 8:1 transmission ratio is used, the number of input second permanent magnets 14 is 16 plus the number of output first permanent magnets 11 is 2 divided by 2, which equals 9, that is, 9 metal iron blocks are required. The externally threaded isolation disk with built-in metal iron block 4 can be called a magnetic exchanger. Its function is to transmit the magnetic field given to it by the second permanent magnet 14, and then transmit it to the first permanent magnet 11, thereby driving the first permanent magnet 11. The principle is the same as the magnetic coupling principle.

[0032] In order to facilitate lateral loading and unloading and replacement, lateral disassembly openings are provided on the outer arc surfaces of the annular drainage cover 4, the lateral fixing box 5 and the annular external transmission box 6, and an external closing cover plate 15 is fixedly installed inside the lateral disassembly opening.

[0035] Lateral limit slots are symmetrically provided on the inner side of the lateral assembly slot 16, and then lateral limit blocks are symmetrically arranged on both sides of the first permanent magnet 11 and the second permanent magnet 14 and inserted into the lateral limit slots to improve assembly stability and avoid outward centrifugal force caused by high-speed rotation.

[0040] In order to cooperate with the linkage control, an internal driving impeller 22 for driving the centrifugal cooling fan 19 is movably installed at the liquid inlet position inside the top cooling water tank 3. The internal driving impeller 22 is inserted into the internal transmission box 21 through the upper linkage shaft and is connected to the centrifugal cooling fan 19.

[0041] High-pressure cooling also flows in from the liquid inlet of the top cooling water tank 3, and then impacts one side of the internal driving impeller 22. The internal driving impeller 22 starts to rotate, and drives the gear set in the internal transmission box 21 to rotate through the upper linkage shaft, and synchronously drives the centrifugal cooling fan 19 to rotate at high speed.

[0042] In order to improve the driving stroke, the inner side surface of the top heat dissipation water tank 3 is located outside the inner driving impeller 22 and has an arc-shaped guide cover 23 for improving the driving stroke.

[0043] In order to improve the internal heat conduction performance, five integrated heat dissipation copper sheets 24 are fixed inside the top heat dissipation water tank 3 .

[0044] The upper and lower ends of the heat dissipation copper sheet 24 are respectively fixed to the inner top surface and the inner bottom surface of the top heat dissipation water tank 3 .

[0045] A motor with a linked water-cooling mechanism of the present invention adopts the magnetic coupling principle to drive a magnetic coupling hydraulic drive device, which can not only reduce friction, but also adopt a non-contact transmission method, which can effectively maintain the sealing of the liquid cooling device and greatly improve durability; a detachable structural design is adopted, and the transmission ratio of the transmission can be freely changed as needed, the adjustability is greatly improved, and the scope of application is wider; a top cooling water tank with an upper centrifugal cooling fan 19 is installed on the top of the external cover 2, and the internal driving impeller 22 located at the liquid inlet position inside the top cooling water tank 3 is used to drive the centrifugal cooling fan 19 to rotate, thereby greatly improving the heat dissipation performance of the top cooling water tank 3; top liquid cooling is used to improve the active and passive heat dissipation performance of the motor, and the heat dissipation effect is more excellent; an external mounting method is used to fix and assemble with the right side wall of the external cover 2, and the sealing surface will not generate friction, and the assembly sealing mechanism will not generate loss, the later loss is low, and the use cost is lower.
