Description

Technical Field

[0001] This utility model relates to the field of servo driver technology, specifically a heat-dissipating servo driver. Background Technology

[0002] In industrial automation and control systems, servo drives are key components, and their performance and stability are crucial to the operation of the entire system. However, with the continuous increase in the power of servo drives and the increasing complexity of the working environment, the heat generated inside them has also increased dramatically, which puts forward higher requirements for the heat dissipation system.

[0003] Traditional heat dissipation methods, such as relying solely on air cooling or natural heat dissipation, are no longer sufficient to meet the heat dissipation requirements of high-power servo drives. Although air cooling can reduce the temperature of the device to some extent, its heat dissipation effect is limited under high load and long-term operation. Natural heat dissipation is even less able to meet the high heat dissipation requirements of modern servo drives. Therefore, we propose a heat-dissipating servo drive that combines liquid cooling and air cooling to achieve a more efficient heat dissipation effect. Utility Model Content

[0016] Example 1

[0017] like Figures 1 to 4As shown, this utility model discloses a heat-dissipating servo driver. The technical solution includes a base 1 and a servo driver body 2. Fixing holes 16 are provided at the four corners of the bottom of the base 1. The servo driver body 2 is located at the center of the top of the base 1. Connecting bolts 15 are provided at both the front and rear ends of the servo driver body 2. The connecting bolts 15 pass through connecting ears 14 provided at the bottom of the front and rear sides of the servo driver body 2 and are threaded into screw holes provided on the base 1. The threaded connection of the connecting bolts 15 through the connecting ears 14 on the front and rear sides of the servo driver body 2 and into screw holes on the base 1 ensures that the servo driver body 2 is stable and does not wobble. Mounting plates 8 are provided in the middle of the left and right sides of the servo driver body 2. Through holes are provided in the four corners of the mounting plates 8. The fixing bolts 9 are threadedly connected to the screw holes on the left and right sides of the servo driver body 2. Heat sinks 10 are arranged in an evenly spaced array on the outer side of the mounting plate 8, with first connecting pipes 11 and second connecting pipes 12 spaced apart between them. The first connecting pipes 11 are located at the top front end between the heat sinks 10, and their left and right ends are connected to the interior of the adjacent heat sink 10. The second connecting pipes 12 are located at the bottom rear end between the heat sinks 10, and their left and right ends are connected to the interior of the adjacent heat sink 10. Liquid guide pipes 17 are respectively provided at the bottom outer side of the heat sinks 10 at both the front and rear ends of the mounting plate 8, and these liquid guide pipes 17 are connected to the cooling unit 5 located at the bottom of the base 1. Next, the cooling unit 5 includes a pump body 51, a U-shaped fixed tube 52, a liquid storage tank 53, a liquid injection pipe 55, a return pipe 56, and pipe connectors 57. Two U-shaped fixed tubes 52 are provided, one at the front end and one at the rear end of the base 1. Pipe connectors 57 are provided at the top left and right ends of each U-shaped fixed tube 52, and these connectors 57 are connected to the liquid guide pipe 17. A liquid storage tank 53 is located between the U-shaped fixed tubes 52 and is fixedly installed at the bottom center of the base 1. A liquid injection pipe 55 is provided at the front end of the liquid storage tank 53, and a sealing cap is threaded onto the front end of the injection pipe 55. A return pipe 56 is connected to the front end of the liquid storage tank 53, and the other end of the return pipe 56 is connected to the bottom of the U-shaped fixed tube 52 at the front end of the base 1. The liquid storage tank 53... A pump body 51 is installed at the rear end and is fixedly mounted on the bottom of the base 1. The liquid inlet pipe of the pump body 51 is connected to the bottom of the rear end of the liquid storage tank 53, and the liquid outlet pipe of the pump body 51 is connected to the bottom of the U-shaped fixed pipe 52 at the rear end of the base 1. By starting the pump body 51, the coolant in the liquid storage tank 53 is drawn out and sent into the U-shaped fixed pipe 52 through the liquid outlet pipe. The coolant flows in the U-shaped fixed pipe 52 and enters the liquid guide pipe 17 through the pipe joint 57, and then flows into the heat sink 10. The heat sink 10 uses the principle of liquid conduction to remove the heat generated by the servo drive body 2. The coolant after absorbing heat through the heat sink 10 flows out through the second connecting pipe 12 and returns to the liquid storage tank 53 through the return pipe 56.After completing the heat dissipation cycle, the cooling unit 5 also includes a temperature sensor 54, which is located at the bottom of the liquid storage tank 53. The detection end of the temperature sensor 54 is located at the bottom inner side of the liquid storage tank 53. The temperature sensor 54 monitors the temperature of the coolant in the liquid storage tank 53 in real time. Heat dissipation slots 13 are arranged in an equidistant array on the front and rear sides of the heat dissipation plate 10. A heat dissipation window 4 is provided below the heat dissipation plate 10. A cooling fan 6 is fixedly installed on the bottom inner side of the heat dissipation window 4. A protective net 7 is provided on the top inner side of the heat dissipation window 4. The operation of the cooling fan 6 allows airflow to pass through the heat dissipation plate 10. The base 1 includes a pump body 51 and a cooling vent 13 to enhance airflow and accelerate heat dissipation. It also includes a controller 3, located on the upper right front surface of the base 1. The controller 3's output is electrically connected to the input of the pump body 51 and the cooling fan 6, while its input is electrically connected to the output of the temperature sensor 54 and an external power supply. The controller 3 allows operators to easily control the pump body 51 and the cooling fan 6. Simultaneously, the controller 3 receives signals from the temperature sensor 54, enabling the removal of the sealing cap on the injection pipe 55 to replace the coolant in the storage tank 53.

[0018] The working principle of this utility model is as follows: First, the heat-dissipating servo drive body 2 is stably installed in the required working position through the fixing hole 16 on its base 1. As the core component, the servo drive body 2 is installed at the top center of the base 1. The connecting bolts 15 pass through the connecting ears 14 on the front and rear sides of the servo drive body 2 and are threadedly connected to the screw holes on the base 1 to ensure that the servo drive body 2 is stable and does not shake. When the servo drive starts working, it will generate a certain amount of heat. In order to effectively dissipate heat, the heat dissipation plates 10 on the mounting plates 8 located in the middle of the left and right sides of the servo drive body 2 will start to play their role. The heat dissipation plates 10 are connected to each other through the first connecting pipe 11 and the second connecting pipe 12 to form a closed cooling liquid circulation channel. Second, the pump body 51 is started by the controller 3 to draw out the cooling liquid in the liquid storage tank 53 and send it into the liquid delivery pipe. The coolant flows through the U-shaped fixed tube 52 and enters the liquid guide tube 17 through the pipe joint 57, then flows into the heat sink 10. The heat sink 10 uses the principle of liquid conduction to carry away the heat generated by the servo drive body 2. After the coolant absorbs heat through the heat sink 10, it flows out through the second connecting pipe 12 and returns to the liquid storage tank 53 through the return pipe 56, completing the heat dissipation cycle. In order to further improve the heat dissipation effect, the cooling fan 6 at the bottom inside the heat dissipation window 4 starts to work, generating airflow. Through the heat dissipation groove 13 on the heat sink 10, the airflow is enhanced and the heat dissipation is accelerated. Finally, the temperature sensor 54 monitors the temperature of the coolant in the liquid storage tank 53 in real time and transmits the temperature signal to the controller 3. When the temperature of the coolant reaches the set temperature, the sealing cap on the injection pipe 55 can be removed to replace the coolant in the liquid storage tank 53.
