Description

Technical Field

[0001] This utility model relates to the field of motor cooling, specifically to a water cooling device for a torque motor. Background Technology

[0002] When a torque motor is in use, its temperature will continuously rise. To ensure the normal operation of the torque motor, it needs to be cooled. Traditional motor cooling methods mainly use a fan that rotates synchronously with the spindle to blow axial airflow to cool the motor. However, this method increases the motor's power consumption, and the uneven distribution of airflow along the motor's axis affects the heat dissipation effect. In addition, air cooling also produces considerable noise. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a water cooling device for a torque motor.

[0004] To achieve the above objectives, the technical solution adopted by this utility model includes: an outer shell having vertically spaced accommodating spaces formed thereon; a top cover disposed on the top of the outer shell, the bottom of the top cover having water inlet grooves that are spaced apart and not connected; a bottom cover disposed on the bottom of the outer shell, the top of the bottom cover having return grooves that correspond to the number of water inlet grooves and are not connected; and a cooling tile having a first flow channel and a second flow channel that are vertically penetrating and separated from each other, the cooling tile being disposed within the accommodating spaces;

[0005] Each of the return channels is connected to the first flow channel and the second flow channel of the cooling tile, and each water inlet channel is connected to the first flow channel of the cooling tile corresponding to one of the return channels and to the second flow channel of the cooling tile corresponding to the adjacent return channel.

[0006] This application configures the flow path of cooling water to be serpentine within the inlet tank, first flow channel, second flow channel, and return tank, thereby fully allowing the cooling water to flow over the surface of the outer casing and cool the rotor installed inside the outer casing.

[0009] In the preferred embodiment of the water-cooling device for the torque motor described above, a second sealing element is provided between the bottom of the outer casing and the bottom cover. The second sealing element has a third channel and a fourth channel spaced apart from each other. The third channel is connected to the first flow channel of the cooling tile, and the fourth channel is connected to the second flow channel of the same cooling tile.

[0010] In the preferred embodiment of the water cooling device for the torque motor described above, a stepped layer is provided on the top surface of the bottom cover around the reflux groove, and an arc-shaped gasket is disposed in the stepped layer. The arc-shaped gasket has a first arc-shaped hole and a second arc-shaped hole.

[0011] In the preferred embodiment of the water-cooling device for the torque motor described above, the cooling tile is fixedly disposed within the accommodating space of the outer casing by means of bolts.

[0012] In the preferred technical solution of the water cooling device for the torque motor described above, the shape of the first flow channel and the second flow channel is one of the following: straight, serpentine, or arc-shaped.

[0013] In the preferred embodiment of the water cooling device for the torque motor, the inlet tank, the first flow channel, the second flow channel and the return tank are coated with polytetrafluoroethylene coating.

[0014] The beneficial effects of this utility model are that by having the cooling water flow in a serpentine path in the inlet tank, the first flow channel, the second flow channel and the return tank, the cooling water can fully flow over the surface of the outer shell, thereby cooling the rotor installed inside the outer shell.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1 to 6 As shown, the water-cooling device for the torque motor of this utility model includes: an outer shell 1, on which vertical and spaced-apart accommodating spaces 11 are formed; a top cover 2, disposed on the top of the outer shell 1, with spaced-apart and non-connected water inlet grooves 21 at the bottom of the top cover 2; a bottom cover 3, disposed on the bottom of the outer shell 1, with a number of non-connected return grooves 31 corresponding to the number of water inlet grooves 21 at the top of the bottom cover 3; and a cooling tile 4, having a vertically penetrating and spaced-apart first flow channel 41 and a second flow channel 42, wherein the cooling tile 4 is disposed within the accommodating space 11; wherein each return groove 31 is connected to the first flow channel 41 and the second flow channel 42 of the cooling tile 4 respectively, each water inlet groove 21 is connected to the first flow channel 41 of the cooling tile 4 corresponding to a return groove 31, and is connected to the second flow channel 42 of the cooling tile 4 corresponding to an adjacent return groove 31.

[0026] See Figures 1 to 4The outer casing 1 is the motor stator, and its cross-section is approximately annular. Eight vertically spaced accommodating spaces 11 are formed on the outer surface of the outer casing 1. The inner surfaces of the accommodating spaces 11 are arc-shaped. A ring-shaped top cover 2 is screwed onto the top of the outer casing 1. Eight non-connected water inlet grooves 21 are formed on the bottom surface of the top cover 2. A ring-shaped bottom cover 3 is screwed onto the bottom of the outer casing 1. Eight non-connected return grooves 31 are formed on the bottom surface of the bottom cover 3. Each accommodating space 11 of the outer casing 1 is equipped with a cooling tile 4. A first flow channel 41 and a second flow channel 42 are vertically and non-connected on the cooling tile 4. It should be noted that the top surface of the top cover 2 has a water inlet 22 and a water outlet 23, both of which are connected to the same water inlet groove 21.

[0027] See Figures 1 to 3 When the water cooling device of this application is assembled, a water inlet trough 21 at the bottom of the top cover 2 is connected to the first flow channel 41 in a cooling tile 4 and is connected to the second flow channel 42 in an adjacent cooling tile 4. A return trough 31 at the bottom of the bottom cover 3 is connected to the first flow channel 41 and the second flow channel 42 of the cooling tile 4.

[0028] Specifically, when cooling the rotor inside the outer casing 1, cooling circulating water is first introduced into the water inlet trough 21 of the top cover 2 through the water inlet 22. Then, the cooling water flows into the return trough 31 through the first flow channel 41 of the cooling tile 4, and after circulating in the return trough 31, it flows back to the second flow channel 42 of the cooling tile 4. After that, the cooling water enters the next water inlet trough 21 of the top cover 2, and so on, until finally the cooling water flows back to the initial water inlet trough 21 of the top cover 2 and is discharged through the water outlet 23. The cooling water flows in a serpentine flow path in the water inlet trough 21, the first flow channel 41, the second flow channel 42 and the return trough 31, so that the cooling water flows through the surface of the outer casing 1, thereby cooling the rotor installed inside the outer casing 1. It has the characteristics of high cooling efficiency, simple structure and low production cost, and is practical.

[0029] In one or more embodiments, a locking member 12 is disposed in the accommodating space 11 of the outer shell 1, and the inner side of the cooling tile 4 has a locking groove 43 that is adapted to and limits the locking member 12.

[0030] See Figures 2 to 5The locking member 12 is a vertically arranged locking strip within the accommodating space 11. The cross-section of the locking strip is approximately an isosceles trapezoidal shape. The locking groove 43 on the inner side of the cooling tile 4 is adapted to the shape of the locking member 12. Specifically, when the cooling tile 4 is installed in the accommodating space 11 of the outer shell 1, the locking member 12 and the locking groove 43 are aligned vertically, and then the cooling tile 4 is moved down so that the locking member 12 enters the locking groove 43 of the cooling tile 4. Since both the locking member 12 and the locking groove 43 are trapezoidal structures, the cooling tile 4 is restricted by the locking member 12 within the accommodating space 11 of the outer shell 1, so that the cooling tile 4 can only move vertically within the accommodating space 11 and not move radially, thereby improving the fixing effect of the cooling tile 4 in this application.

[0031] In one or more embodiments, a first sealing member 5 is disposed between the top of the outer shell 1 and the top cover 2. The first sealing member 5 has a first channel 51 and a second channel 52 spaced apart from each other. The first channel 51 connects to the first flow channel 41 of the cooling tile 4, and the second channel 52 connects to the second flow channel 42 of the adjacent cooling tile 4. A second sealing member 6 is disposed between the bottom of the outer shell 1 and the bottom cover 3. The second sealing member 6 has a third channel 61 and a fourth channel 62 spaced apart from each other. The third channel 61 connects to the first flow channel 41 of the cooling tile 4, and the fourth channel 62 connects to the second flow channel 42 of the same cooling tile 4.

[0032] See Figures 2 to 6 The first sealing element 5 is disposed between the outer shell 1 and the top cover 2. The first sealing element 5 can be limited and installed between the outer shell 1 and the top cover 2 by a limiting rod. The first sealing element 5 is a ring-shaped thin sheet structure. The material of the first sealing element 5 can be rubber. The first sealing element 5 has eight sets of first channels 51 and eight sets of second channels 52. The first channels 51 and the second channels 52 are evenly distributed around the central axis of the first sealing element 5. The first channels 51 and the second channels 52 are waist-shaped holes.

[0033] See Figures 2 to 6 The second seal 6 is disposed between the outer shell 1 and the bottom cover 3. A rod can be used to pass through the second seal 6 to limit it between the outer shell 1 and the bottom cover 3. The second seal 6 is a ring-shaped thin sheet structure made of rubber. The second seal 6 has eight sets of third channels 61 and eight sets of fourth channels 62. The third channels 61 and fourth channels 62 are evenly distributed around the central axis of the second seal 6. The third channels 61 and fourth channels 62 are waist-shaped holes.

[0034] Specifically, when the first seal 5 is installed between the outer shell 1 and the top cover 2, a first channel 51 and an adjacent second channel 52 of the first seal 5 are connected to a water inlet 21 of the top cover 2. That is, the first flow channel 41 of a cooling tile 4 is connected to the water inlet 21 of the top cover 2 through the first channel 51 of the first seal 5, and the second flow channel 42 of an adjacent cooling tile 4 is connected to the water inlet 21 of the top cover 2 through the second channel 52 of the first seal 5. When the second seal 6 is installed between the outer shell 1 and the bottom cover 3, the third channel 61 and the fourth channel 62 of the second seal 6 are respectively connected to the first flow channel 41 and the second flow channel 42 of the same cooling tile 4.

[0035] When cooling the rotor, cooling water enters the inlet tank 21 through the inlet 22 and enters the first flow channel 41 of the cooling tile 4 through the first channel 51 of the first seal 5. Subsequently, the cooling water enters the return tank 31 of the bottom cover 3 through the third channel 61 of the second seal 6. The cooling water accumulates in the return tank 31 to form a high-pressure water flow, so that the cooling water in the return tank 31 enters the second flow channel 42 of the cooling tile 4 through the fourth channel 62 of the second seal 6. Then, the cooling water enters the next inlet tank 21 through the second channel 52 of the first seal 5. This process is repeated, and the cooling water can form a serpentine loop to dissipate heat from the outer casing 1 and the rotor inside the outer casing 1. By setting the first seal 5 between the outer casing 1 and the top cover 2 and the second seal 6 between the outer casing 1 and the bottom cover 3, this application can effectively reduce the possibility of cooling water leakage through the gap between the outer casing 1 and the top cover 2 and the bottom cover 3, thereby improving the performance and safety of this application.

[0036] In one or more embodiments, a stepped layer 32 is provided on the top surface of the bottom cover 3 around the reflux groove 31. An arc-shaped gasket 7 is disposed in the stepped layer 32. The arc-shaped gasket 7 has a first arc-shaped hole 71 and a second arc-shaped hole 72. The first arc-shaped hole 71 is directly opposite to the third channel 61 of the second seal 6, and the second arc-shaped hole 72 is directly opposite to the fourth channel 62 of the second seal 6.

[0037] See Figure 2 , Figure 6 The arc-shaped gasket 7 has a waist-shaped structure for both the first arc-shaped hole 71 and the second arc-shaped hole 72. The arc-shaped gasket 7 is made of hard metal and is used to buffer the cooling water in the return groove 31, reducing the problem of excessive cooling water pressure in the return groove 31 directly impacting the second seal 6 and thus reducing the service life of the second seal 6.

[0038] In one or more embodiments, the cooling tile 4 is fixedly disposed within the receiving space 11 of the outer casing 1 by means of bolts.

[0039] See Figures 1 to 5This arrangement allows for further fixation of the cooling tile 4, improving the stability of the water-cooling device after assembly.

[0040] In one or more embodiments, the shape of the first flow channel 41 and the second flow channel 42 is one of a straight line, a serpentine shape, or an arc shape.

[0041] In one or more embodiments, the inlet tank 21, the first flow channel 41, the second flow channel 42, and the return tank 31 are coated with a polytetrafluoroethylene (PTFE) coating. It should be noted that the PTFE coating has a certain self-lubricating effect, which can effectively reduce the possibility of corrosion in the inlet tank 21, the first flow channel 41, the second flow channel 42, and the return tank 31, ensuring the effective circulation of cooling water.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
