摘要
本文研究了空调变频基板制冷剂散热的关键技术问题,包括制冷剂散热板的设计、加工、性能检验方式等,最终实现该技术的实际应用。研究了制冷剂散热板应用于空调变频基板时,如何选用合适的导热垫片来辅助散热片与发热体之间进行更好的传热。通过实验方式优选出膨胀接头与铜管的配合尺寸,同时设计合理的实验方法来测试散热板的散热性能,测试结果可以判定加工方式的优劣。
This study focuses on the key technology of refrigerant cooling to the frequency conversion board in air conditioning. Specifically, the design, manufacture and performance test method of a refrigerant cooling board are studied, and a practical prototype of the technology is then developed. In addition, how to choose a suitable thermal pad to enhance the heat transfer between the cooling board and heating element is studied. An experiment was conducted to select the best size for the expanding head and copper tube. A reasonable experiment was also developed to test the heat dissipation performance of the cooling board. The results revealed whether the processing methods of the refrigerant cooling board work or not. This study′s methods and results provide strong support for the practical application of this technology.
