Description

Technical Field

[0001] The invention relates to the technical field of motor heat dissipation devices, in particular to a motor water cooling device. Background Art

[0002] When the motor is running in a high temperature environment in summer, the stator bore temperature is high, which causes serious heating of the bearing, affecting the bearing life and causing adverse reactions to the deterioration of the grease in the bearing. Most motors now use external axial cooling fans to cool the motors, but in high ambient temperatures, the cooling effect of the axial cooling fan is significantly weakened. After increasing the capacity and speed of the axial fan, the cooling effect has not been significantly improved.

[0003] Moreover, during the operation of the motor, the area where heat is concentrated is not static. The motor consumes grease all the time during operation, so it needs to be added from time to time. When grease is just added to the motor, the grease enters the bearing and destroys the originally formed oil film. At this time, the motor end cover is seriously heated and the temperature is high. When the oil film is re-formed and the motor works normally, the temperature of the rotor in the middle of the motor is higher. Therefore, it is necessary to use water cooling according to the different heating conditions of the motor in combination with the original air cooling. Summary of the invention

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, reference Figure 1 to Figure 2 , is the first embodiment of the present invention, which provides a motor water cooling device, including a spray mechanism 100, the spray mechanism 100 uses the flow of the water cooling pipe to form water mist-type water droplets and spray them on the side wall cooling fins of the motor, and cools the high-temperature motor through the evaporation ability of the low-temperature atomized water. The spray mechanism 100 includes a nozzle structure 101 and an adjustment structure 102 arranged on the side of the nozzle structure 101. The nozzle structure 101 converts water into water mist and sprays it to the motor. The adjustment structure 102 can adjust the water cooling position of the motor according to the heating condition of the motor to obtain greater efficiency and save energy; and,

[0025] The pumping mechanism 200 includes a water distribution pipe structure 201 disposed on the side of the nozzle structure 101, a main water pipe 202 disposed on the side of the water distribution pipe structure 201, and a water pump 203 disposed on the side of the main water pipe 202. The water pump 203 pumps cooling water into the main water pipe 202. The cooling water flows into the water distribution pipe through the main water pipe 202. The cooling water flows into the nozzle structure 101 through the water distribution pipe. The cooling water is converted into water mist and sprayed to the motor for water cooling; and

[0026] The supporting mechanism 300 supports the entire spraying mechanism 100 and ensures that it maintains an arc-shaped area surrounding the outer periphery above the motor to form a better water cooling effect.

[0027] Specifically, when the motor needs to be water-cooled, the spray mechanism 100 is installed on the periphery of the motor using the support mechanism 300, and the water pump 203 pumps cooling water into the main water pipe 202. The cooling water flows into the water branch pipe through the main water pipe 202, and the cooling water flows into the nozzle structure 101 through the water branch pipe. The cooling water is converted into water mist and sprayed on the motor for water cooling. When the concentrated heating area of ​​the motor changes, such as when the motor end cover is seriously heated, the spray position can be adjusted using the adjustment structure 102, and water cooling can be sprayed on the end cover of the motor. When the temperature in the middle of the motor is high, the adjustment structure 102 will adjust the spray position to spray the middle of the motor.

[0028] Example 2, reference Figure 1 to Figure 2 , which is the second embodiment of the present invention. Different from the previous embodiment, the nozzle structure 101 includes a water spray pipe 101a, and an atomizing nozzle 101b is arranged at the bottom of the water spray pipe 101a. Specifically, a hole is opened inside the water spray pipe 101a, and the hole diameter is 3mm. After the hole is opened, the atomizing nozzle 101b with a rubber seal is used to fill it, so that the water spray pipe 101a can spray atomized water droplets, and the atomizing nozzle 101b is connected to the water spray pipe 101a.

[0029] Furthermore, a connecting end cover 101c is provided at one end of the water spray pipe 101a, and an arc-shaped through groove 101d is provided on the outer wall of the connecting end cover 101c, and the arc-shaped through groove 101d passes through the connecting end cover 101c. The adjusting structure 102 includes an arc-shaped connecting plate 102a, and a transverse support plate 102b is provided on the inner wall of the arc-shaped connecting plate 102a. An arc-shaped partition plate 102c is provided on the side of the arc-shaped connecting plate 102a. One end of the arc-shaped partition plate 102c away from the arc-shaped connecting plate 102a passes through the arc-shaped through groove 101d and extends into the water spray pipe 101a. The bottom of the arc-shaped partition plate 102c contacts the atomizing nozzle 101b. When it is necessary to adjust the water spray position, the transverse support plate 102b can be pushed and pulled to drive the arc-shaped connecting plate 102a to slide, and drive the arc-shaped partition plate 102c to slide in the water spray pipe 101a. When it is necessary to water-cool the end of the motor, The arc partition 102c is driven to slide in the direction close to the support mechanism 300, blocking most of the atomizing nozzles 101b. Only a part of the atomizing nozzles 101b close to the support mechanism 300 can work and spray. The support mechanism 300 is set at one end of the motor end cover. At this time, the spraying mechanism 100 will concentrate on spraying water cooling on the motor end cover to cope with the rapid heating of the end cover of the motor that has just been lubricated with grease. When the oil film at the motor end cover is re-formed, the rotor movement in the middle of the motor becomes the most seriously heated part after the motor runs normally. At this time, the horizontal support plate 102b can be pulled to make the arc partition 102c slide in the direction away from the support mechanism 300, so that the atomizing nozzles 101b close to the middle of the motor can also spray and cool the middle of the motor with water. The water cooling strategy is adjusted according to different heating conditions to save energy.

[0030] Furthermore, the water distribution pipe structure 201 includes an arc-shaped water pipe 201a, which is arranged on one side of the water spray pipe 101a. An auxiliary water pipe 201b is arranged at the bottom of the arc-shaped water pipe 201a. The side of the arc-shaped water pipe 201a is connected to the main water pipe 202. The cooling water drawn by the water pump 203 enters the arc-shaped water pipe 201a through the main water pipe 202. The side of the auxiliary water pipe 201b is in contact with the connecting end cover 101c. One end of the auxiliary water pipe 201b passes through the connecting end cover 101c. The auxiliary water pipe 201b is connected to the water spray pipe 101a, and the top of the auxiliary water pipe 201b is connected to the arc-shaped water pipe 201a.

[0031] Specifically, when the motor needs to be water-cooled, the cooling water pumped by the water pump 203 enters the arc-shaped water pipe 201a through the main water pipe 202, and the cooling water flows from the arc-shaped water pipe 201a through the auxiliary water pipe 201b into each water spray pipe 101a, and then is converted into water mist by the atomizing nozzle in the water spray pipe 101a to spray the motor with water cooling. When the end of the motor needs to be water-cooled, the arc-shaped partition plate 102c can be driven to slide toward the direction close to the support mechanism 300, thereby blocking most of the atomizing nozzles 101b, and only a part of the atomizing nozzles 101b close to the support mechanism 300 is blocked. 01b can work by spraying, and the supporting mechanism 300 is arranged at one end of the motor end cover. At this time, the spraying mechanism 100 will concentrate on spraying water cooling to the motor end cover to cope with the rapid heating of the end cover of the motor that has just been lubricated with grease. When the oil film at the motor end cover is re-formed, the rotor movement in the middle of the motor becomes the most seriously heated part after the motor runs normally. At this time, the horizontal support plate 102b can be pulled to make the arc partition 102c slide away from the supporting mechanism 300, so that the atomizing nozzle 101b near the middle of the motor can also spray and cool the middle of the motor with water.

[0032] Example 3, reference Figure 1 to Figure 2 , which is the third embodiment of the present invention. Different from the previous embodiment, the supporting mechanism 300 includes a first support plate 301, a connecting pin 302 is arranged on the side of the first support plate 301, one end of the first support plate 301 is connected to the water spray pipe 101a, and a second support plate 304 is arranged on the side of the first support plate 301. The first support plate 301 and the second support plate 304 are multiple groups, each group is arranged between two adjacent water spray pipes 101a, and the two water spray pipes 101a are connected together, so that multiple groups of water spray pipes 101a can be connected together to maintain an arc state.

[0033] Furthermore, a transverse groove 305 is provided on the outer wall of the second support plate 304, and the connecting pin 302 is arranged inside the transverse groove 305. An L-shaped groove 306 is provided on the side of the transverse groove 305, and a separation pin 303 is arranged inside the L-shaped groove 306. The side of the separation pin 303 is connected to the first support plate 301. When it is necessary to support the overall arc structure of the spray mechanism 100, the separation pin 303 is inserted into the L-shaped groove 306 to connect the first support plate 301 and the second support plate 301. 4 move toward each other respectively, and push the separation pin 303 into the closed area of ​​the L-shaped groove. At this time, the first support plate 301 and the second support plate 304 are kept in the same straight line by the connecting pin 302 and the separation pin 303, and the two adjacent water spray pipes 101a cannot move relative to each other. At the same time, the friction between the connecting pin 302, the separation pin 303 and the groove body, and the neutrality of the spray mechanism 100 itself on the arc structure are used to squeeze the two support plates toward each other so that they cannot be separated.

[0034] Specifically, due to weather changes, a water cooling device is not always needed. When the motor needs to be sprayed with water for cooling, the first support plate 301 and the second support plate 304 are kept in the same straight line by the connecting pin 302 and the separating pin 303, so that multiple groups of water spray pipes 101a can be connected together to maintain an arc state, and the motor is water-cooled. In cold weather, when it is not necessary to install a water cooling device on the motor, the end of the water spray pipe 101a close to the arc-shaped water pipe 201a can be connected from the connecting end cap. 101c, then pull the first support plate 301 and the second support plate 304 away from each other, pull the separation pin 303 to the open area at one end of the L-shaped groove 306, then the first support plate 301 and the second support plate 304 can be rotated, and the separation pin 303 can be rotated out of the L-shaped groove. At this time, the first support plate 301 and the second support plate 304 will be folded relative to each other, and each water spray pipe 101a will be folded together, so that the spray mechanism 100 can be folded and stored for easy storage and transportation.
