Technical Field

[0001] This utility model relates to the field of heat dissipation technology for motors and drives, and in particular to a water-cooling heat dissipation device used for both motors and drives. Background Technology

[0002] In modern motor and drive applications, motors and drives generate a large amount of heat during operation, which has a significant impact on the normal operation and lifespan of the equipment. In order to improve the working efficiency of motors and drives and reduce heat accumulation, heat dissipation technology is particularly important.

[0003] Existing heat dissipation technologies generally employ air cooling or separate water cooling for the motor and driver, but both have certain limitations. Especially for the combined use of high-power motors and drivers, individual cooling methods cannot meet their high-efficiency heat dissipation requirements, resulting in the inability to effectively reduce the temperature of the motor and driver, thus affecting the overall performance of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a water-cooling heat dissipation device that can be used for both a motor and a driver, thus solving the problem of reduced heat dissipation efficiency caused by the inability to simultaneously reduce the temperature of the motor and driver.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A water-cooled heat dissipation device for use in a motor and a driver includes: a motor, a driver, a water-cooling assembly, and a mounting assembly for easy installation and disassembly, wherein the driver is fixedly connected to the top of the motor;

[0007] The mounting assembly includes a fixing assembly fixed to the bottom of the motor, and the fixing assembly has an adjustment assembly inside it;

[0008] The water-cooling assembly includes an IGBT board fixed inside the driver. Above the IGBT board is a water channel base fixed to the top of the driver. A water channel cover is screwed to the top of the water channel base. A water channel insert is fixedly connected to the bottom of the water channel cover. A first water inlet is provided on the side of the motor. A first water outlet is provided on the side of the first water inlet. A second water inlet is provided on one side of the driver and a second water outlet is provided on the other side. A water pipe is fixedly connected between the first water outlet and the second water inlet.

[0009] Preferably, a waterway sealing ring is provided between the waterway base and the waterway cover plate in an interference fit.

[0010] Preferably, the mounting assembly includes: a fixing assembly and an adjusting assembly, wherein the adjusting assembly adjusts the mounting and fixing position of the motor and the driver on the fixing assembly;

[0011] The fixing assembly includes a support plate, a top plate, and a fixing plate. A motor and a driver are placed on top of the support plate. A frame is fixedly connected to the top of the support plate. Fixing columns are fixedly connected to both sides of the frame. One end of the fixing column is fixedly connected to the fixing plate. A second telescopic spring is fixedly connected between the fixing plate and the frame. A first telescopic spring is fixedly connected to the bottom of the frame. The top end of the first telescopic spring is fixedly connected to the top block.

[0012] Preferably, the fixing component further includes: a push frame and a snap-fit ​​post, wherein the push frame is provided above the frame, and the bottom end of the push frame is pushed and engaged with the snap-fit ​​post.

[0013] Preferably, the adjustment component includes: a connecting block and a drive gear. The connecting block is fixedly connected to both sides of the top of the frame. An adjustment rod is rotatably connected inside the connecting block. The surface of the adjustment rod is fixedly connected to the drive gear. The drive gear meshes with a rack plate. A sliding plate is provided below the rack plate. A telescopic rod is fixedly connected to one end of the sliding plate.

[0015] Preferably, the snap-fit ​​post is slidably connected through one end of the rack plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the motor and driver are working, they are placed on the adjustment assembly. The adjustment assembly then slides within the fixed assembly to adjust the motor and driver, which in turn moves the fixed assembly to secure them. During operation, the heat released by the IGBT module is conducted through the water channel base to the water channel teeth within the base. External water is then connected to the first inlet, allowing it to enter. From the first outlet, water flows through a pipe into the second inlet, allowing cold water to flow into the water channel base. The water channel teeth at the bottom of the cover plate then conduct the absorbed heat into the cooling water flow, raising its temperature. The heated water is then discharged to the outside through the second outlet, thus solving the problem of insufficient heat dissipation efficiency caused by the inability to simultaneously lower the temperatures of the motor and driver.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Reference 1- Figure 7 As shown, this utility model embodiment provides a water-cooled heat dissipation device for use in motors and drivers, including: motor 1, driver 2, water-cooling component 3 and mounting component 4 for easy installation and disassembly, wherein the top of the motor 1 is fixedly connected to the driver 2;

[0034] The mounting assembly 4 includes a fixing assembly 410 fixed to the bottom of the motor 1, and an adjustment assembly 420 is provided inside the fixing assembly 410;

[0035] The water-cooling component 3 is used to reduce the temperature of the driver 2 and the motor 1, the fixing component 410 is used for disassembling and installing the driver 2 and the motor 1, and the adjusting component 420 is used to adjust the fixed installation position of the driver 2 and the motor 1;

[0036] The fixing component 410 fixes the driver 2 and the motor 1 on the adjusting component 420. Then the adjusting component 420 adjusts the installation position of the driver 2 and the motor 1. Then the water cooling component 3 removes the temperature of the driver 2 and the motor 1 through the flow of cold water.

[0037] refer to Figure 1 , Figure 2 and Figure 3 As shown, the water-cooling assembly 3 includes an IGBT board 301 fixed inside the driver 2. Above the IGBT board 301 is a water channel base 302 fixed to the top of the driver 2. A water channel cover plate 303 is screwed to the top of the water channel base 302. A water channel insert 304 is fixedly connected to the bottom of the water channel cover plate 303. A first water inlet 305 is provided on the side of the motor 1. A first water outlet 306 is provided on the side of the first water inlet 305. A second water inlet 309 is provided on one side of the driver 2 and a second water outlet 307 is provided on the other side. A water pipe 308 is fixedly connected between the first water outlet 306 and the second water inlet 309.

[0038] When motor 1 and driver 2 are in use, their IGBT board 301 generates heat. The heat released by the IGBT board 301 is conducted through the water channel base 302 to the water channel insert 304 inside the water channel base 302. Then, the external water source is connected to the first water inlet 305, so that cold water enters the first water outlet 306 through the first water inlet 305. Then, the cold water flows from the first water outlet 306 through the water pipe 308 to the second water inlet 309, so that the cold water flows into the water channel base 302. The water channel sealing ring 5 prevents the cold water from seeping out of the water channel base 302 through its own sealing. Then, the water channel insert 304 at the bottom of the cover plate begins to conduct the absorbed heat into the water cooling flow, so that the temperature of the water cooling flow rises. Then, the heated water cooling is discharged to the outside through the second water outlet 307.

[0039] refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the fixing component 410 includes: a support plate 411, a top plate 417, and a fixing plate 414. A motor 1 and a driver 2 are placed on top of the support plate 411. A frame 412 is fixedly connected to the top of the support plate 411. Fixing columns 413 are fixedly connected to both sides inside the frame 412. One end of the fixing column 413 is fixedly connected to the fixing plate 414. A second telescopic spring 415 is fixedly connected between the fixing plate 414 and the frame 412. A first telescopic spring 416 is fixedly connected to the bottom inside the frame 412. The top end of the first telescopic spring 416 is fixedly connected to the top plate 417.

[0040] The fixing component 410 further includes a pusher frame 418 and a snap-fit ​​post 419. The pusher frame 418 is provided on the top of the frame 412, and the bottom end of the pusher frame 418 pushes and engages with the snap-fit ​​post 419.

[0041] The motor 1 and driver 2 are placed in the frame 412 on the support plate 411. The motor 1 begins to press the top plate 417 downward within the frame 412. The top plate 417 presses down on the first telescopic spring 416. Then, the motor 1 presses the top plate 417 into the frame 412, so that the top plate 417 pushes the motor 1 upward through the first telescopic spring 416. At the same time, the motor 1 pushes the fixing plate 414 into the frame 412 to press the second telescopic spring 415. The second telescopic spring 415 pushes the fixing plate 414 with its rebound force, so that the fixing plate 414 is fixedly engaged with the motor 1. Then, the pusher 418 is manually pushed downward, so that the pusher 418 pushes the engaging post 419 downward to abut against the motor 1, so that the motor 1 and driver 2 are fixedly installed in the frame 412.

[0042] refer to Figure 1 , Figure 4 and Figure 5 As shown, the adjustment assembly 420 includes a connecting block 421 and a drive gear 423. The connecting block 421 is fixedly connected to both sides of the top of the frame 412. An adjustment rod 422 is rotatably connected inside the connecting block 421. The surface of the adjustment rod 422 is fixedly connected to the drive gear 423. The drive gear 423 meshes with a rack plate 424. A sliding plate 425 is provided below the rack plate 424. A telescopic rod 426 is fixedly connected to one end of the sliding plate 425.

[0043] While the motor 1 and driver 2 are placed inside the frame 412, the motor 1 and driver 2 will slide within the frame 412 in contact with the sliding plate 425. The sliding plate 425 will compress the telescopic rod 426 to retract. When it is necessary to adjust the position of the locking pin 419 to fix the motor 1, the adjusting rod 422 inside the connecting block 421 is rotated. The adjusting rod 422 drives the drive gear 423 to rotate. Subsequently, the drive gear 423 drives the rack plate 424 to move through meshing. The rack plate 424 drives the locking pin 419 to move synchronously, thereby changing the position of the locking pin 419 to fix the motor 1.
