The interval between the flow-guiding plates 15 should be determined according to the flow rate and flow quantity of the cooling liquid to ensure uniform distribution of the cooling liquid and effective heat transfer. The material of the drainage plate 15 should be selected to have good heat conduction properties, such as aluminum or copper, in order to transfer heat rapidly. The number of the flow-guiding plates 15 should be determined according to the size of the cooling plate and the intended cooling efficiency to ensure a sufficient heat exchange area. The drainage plates 15 should be positioned on the inner walls of the liquid-exchanging cooling plates 3 and the heat-dissipating cooling plates 4 in order to facilitate the guiding and distribution of the cooling liquid.

The working principle of the embodiment of the invention is as follows:
First, the user places the device in the mounting area, ensuring that the mounting point is located between the two clamping blocks 40. This action will then cause the bi-directional threaded rod 41 to rotate by rotating the fixing knob 42. Along with the rotation of the bidirectional threaded rod 41, the two adjusting blocks 39 are close to each other, so that the two clamping blocks 40 are driven to be close to each other, and the installation and fixation of the device position are realized.
Next, the motor body 1 is placed between the two outer explosion-proof housings 18. By turning the mounting knob 43, this action will cause the first threaded rod 19 to rotate. With the rotation of the first threaded rod 19, the two tightening blocks 20 move respectively and drive the two unfolding frames 21 connected in a rotating way respectively. This causes the angle between the two expansion brackets 21 to gradually decrease, and the expansion brackets 21 further drive the two outer explosion-proof housings 18 to approach each other along the upper sides of the two supports 17, thereby wrapping the motor body 1.
In this process, the two outer explosion-proof housings 18 also respectively drive the first movable cover 24 and the second movable cover 26 to approach each other. After the two outer explosion-proof housings 18 are completely attached, the installation of the motor body 1 can be completed by passing two bolts 23 through the fixing pieces 22 and turning the knob into the outer explosion-proof housing 18.
To adjust the height and angle of the device, the user may turn the lift knob 37, which will turn the second threaded rod 36. With the rotation of the second threaded rod 36, the moving block 34 moves and drives the supporting rod 35 to be gradually vertical to the bottom plate 33. The supporting rod 35 drives the lifting table 31 to lift under the action of the telescopic rods 32.

During the operation of the motor body 1, the secondary heat dissipation fan 27 is started to suck the external air through the sub dust screen 30 and discharge the air from the main dust screen 29 through the motor body 1. Therefore, heat generated in the motor body 1 can be brought out, and normal-temperature heat dissipation of the motor body 1 is realized. If the temperature continues to rise, the heat transfer aluminum jacket 2 transfers the heat generated in the motor to the heat sink cooling plate 4 and the liquid exchange cooling plate 3. This heat will be cooled by the cooling liquid in the radiator cooling plate 4 and the liquid-exchange cooling plate 3, thereby cooling the motor.
In order to further improve the cooling efficiency, the micro water pump 6 is started and the cooling liquid used in the liquid exchange cooling plate 3 is conveyed into the shunt tube 8 through the water conveying pipe 7 by the water inlet pipe 5. The coolant is radiated in the radiating pipe 9 installed on the shunt pipe 8. Meanwhile, the primary heat dissipation fan 12 is started to increase heat circulation among the heat dissipation pipes 9, so that heat dissipation efficiency of the heat dissipation pipes 9 is improved. The cooling liquid after heat dissipation and temperature reduction enters the collecting pipe 10 and reenters the liquid exchange cooling plate 3 through the drain pipe 11 for cooling and heat dissipation again.
Through such design and workflow, the cooling efficiency of the motor body 1 can be remarkably improved, the stable operation of the motor body is ensured, and the service life is prolonged.
