| Abstract: |
| 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 dissipation plate 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 heat dissipation plate. 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. |
