To improve the fin efficiency of G-type embedded fin tubes, the following points can be taken into consideration.

One, optimize the fin design. Increase the height and thickness of the fins within a reasonable range while keeping the degree of control to prevent excessive resistance. Scientifically adjust the fin spacing to enhance heat transfer while ensuring smooth fluid flow and reducing flow resistance. Determine the optimal combination of fin height, thickness, and spacing through numerical simulation and experimental research to improve the fin efficiency.

Second, improve the processing technology. Improve the degree of embedding between the fins and the base tube, and reduce the contact thermal resistance. Utilize advanced processing equipment and technology to improve processing accuracy and ensure that the fin shape and size are accurate, thereby improving the heat transfer performance. For example, use high-precision machine tools to ensure that the fins are tightly attached to the base tube.

Three, select suitable working medium and operating parameters. Based on the application scenario, select a working medium with good heat transfer performance, and reasonably adjust the fluid velocity, temperature, etc. parameters to ensure that the fin tube operates in a good working state and improves the fin efficiency.
