本发明涉及振动台冷却技术领域，具体涉及一种大推力振动台高压功率放大器水冷系统及方法。The invention relates to the technical field of vibration table cooling, and in particular to a water cooling system and method for a high-thrust vibration table high-voltage power amplifier.
背景技术Background technique
电动振动台主要用于模拟试件所受的实际振动环境，进而检测试件的实际工作性能。由于科学技术的迅速发展，目前对振动台的推力要求逐渐增大，为满足大推力振动台的需要，对振动台高压功率放大器的要求也越来越高，而高压功率放大器在工作过程中温度会升高进而影响正常工作的性能，因此，对高压功率放大器的散热变得尤为重要。现有技术中，在对高压功率放大器冷却时主要存在以下缺点与不足：The electric vibration table is mainly used to simulate the actual vibration environment of the test piece, and then test the actual working performance of the test piece. Due to the rapid development of science and technology, the thrust requirements for the vibration table are gradually increasing. In order to meet the needs of the large-thrust vibration table, the requirements for the high-voltage power amplifier of the vibration table are also getting higher and higher. The temperature of the high-voltage power amplifier will increase during operation, thus affecting the performance of normal operation. Therefore, the heat dissipation of the high-voltage power amplifier becomes particularly important. In the prior art, there are mainly the following shortcomings and deficiencies in cooling the high-voltage power amplifier:
（1）目前高压功率放大器冷却主要采用风冷散热装置,对水冷散热装置采用较少，但风冷散热效率较低，对高压功率放大器冷却的散热效果不理想；(1) At present, high-voltage power amplifiers are mainly cooled by air cooling devices, and water cooling devices are rarely used. However, the air cooling efficiency is low, and the heat dissipation effect of high-voltage power amplifiers is not ideal;
（2） 现有的高压功率放大器水冷散热装置中，水冷散热板中的水冷管路通常采用均匀分布的方式，没有考虑到高压功率放大器发热的特点，导致冷却水分配不均匀，对高压功率放大器的散热效果较差；(2) In the existing water-cooling heat dissipation device for high-voltage power amplifiers, the water cooling pipes in the water-cooling heat sink are usually evenly distributed, without considering the heat generation characteristics of the high-voltage power amplifier, resulting in uneven distribution of cooling water and poor heat dissipation effect on the high-voltage power amplifier;
（3）现有的高压功率放大器水冷散热装置中，没有考虑到由于冷却水管路长短不同导致的各个水冷散热板的冷却水的流量不均匀，进而导致对高压功率放大器的散热不理想；(3) The existing water-cooling device for high-voltage power amplifiers does not take into account the uneven flow of cooling water in each water-cooling heat sink due to the different lengths of cooling water pipes, which in turn leads to unsatisfactory heat dissipation for the high-voltage power amplifier;
（4）现有的高压功率放大器水冷散热装置中，各个功率柜间的冷却水均由相同通径的管路提供，而实际中各个功率柜中功率放大器因工作性能差异不可避免存在着发热量差距，导致各个功率柜运行温度存在差异，而采用相同管路供水冷却方式会造成各功率柜冷却性能存在差异，温度一致性较差。(4) In the existing water-cooling device for high-voltage power amplifiers, the cooling water between each power cabinet is provided by a pipe with the same diameter. In practice, the power amplifiers in each power cabinet inevitably have different heat generation due to differences in working performance, resulting in differences in the operating temperatures of each power cabinet. Using the same pipe water supply cooling method will cause differences in cooling performance of each power cabinet and poor temperature consistency.

The system is provided with three power cabinets 11 and a control unit 6. Each power cabinet 11 is provided with a proportional throttle valve 3, three diverter and collector valves 4 and four water-cooled heat sinks 1. A temperature sensor 5 is provided on the pipeline near the cooling water main inlet 7, and a temperature sensor 5 is provided at the cooling water outlet of each water-cooled heat sink 1. The cooling water flow path is: the cooling water is diverted from the cooling water main inlet into the three power cabinets 11, in each power cabinet 11, it first enters the proportional throttle valve 3, then enters the diverter and collector valve 4, and is divided into four paths by the diverter and collector valve to enter each water-cooled heat sink 1, and after absorbing the heat of the power amplifier 2, it comes out from the cooling water outlet, and then merges into a pipeline and comes out from the cooling water main outlet 10. Regarding the control part, the proportional throttle valve 3 in each power cabinet 11 is electrically connected to the control unit 6 , and all the temperature sensors 5 are electrically connected to the control unit 6 .
请参考图2和图3，本发明的水冷散热板1的具体结构为：水冷散热板1为长方体结构，在功率柜11内竖向放置，在水冷散热板1两侧面各设有两个功率放大器2。水冷散热板1的一端中间部位设有一个冷却水进水口8，在上下侧的远端各设有一个冷却水出水口9，冷却水从冷却水进水口8进入中间管路后从成两路，一路向上，一路向下，两个管路呈连续折弯状行进，最后到达上下两个冷却水出水口9处，其它出口均用堵头12密封。两个管路折弯在板的中部处比较稠密，在往冷却水出水口前进中逐渐稀疏。上述管路的疏密分布主要是考虑功率放大器内的电气元件布置，从而可更有针对性地对电气元件布置稠密区与管路稠密区相对应，对功率放大器的散热效果更好。Please refer to Figures 2 and 3. The specific structure of the water-cooled heat sink 1 of the present invention is as follows: the water-cooled heat sink 1 is a rectangular parallelepiped structure, which is placed vertically in the power cabinet 11, and two power amplifiers 2 are arranged on both sides of the water-cooled heat sink 1. A cooling water inlet 8 is arranged in the middle part of one end of the water-cooled heat sink 1, and a cooling water outlet 9 is arranged at the far end of the upper and lower sides. After the cooling water enters the middle pipeline from the cooling water inlet 8, it is divided into two paths, one upward and one downward. The two pipelines are continuously bent and finally reach the upper and lower cooling water outlets 9. The other outlets are sealed with plugs 12. The two pipelines are relatively dense in the middle of the plate, and gradually become sparse as they move toward the cooling water outlet. The sparse and dense distribution of the above pipelines is mainly considered to consider the layout of the electrical components in the power amplifier, so that the dense area of the electrical components can be more targeted to correspond to the dense area of the pipeline, which has a better heat dissipation effect on the power amplifier.
控制单元6与比例节流阀3电连接，可采集其比例调节电压，与温度传感器电连接，可采集冷却水总进水口7处的水温，及每个功率柜11内所有水冷散热板1对功率放大器2吸收热量后的水温进行测量。The control unit 6 is electrically connected to the proportional throttle valve 3, and can collect its proportional adjustment voltage.
