增强管内的湍流器
By combining flattened fins and internal spiral fins on the outer and inner surfaces of the heat exchange tube, and installing a turbulence generator on the inner surface, the problem of insufficient heat transfer efficiency of existing heat exchangers under low temperature and low flow characteristics conditions is solved, achieving a significant improvement in heat transfer coefficient and an expansion of the applicable fluid range.

AI Technical Summary
Existing heat exchangers offer limited improvement in heat transfer efficiency on both the tube and shell sides, especially under low temperature and low flow characteristics, making it difficult to significantly improve the heat transfer coefficient through a single surface feature.
The heat exchange tube employs a combination of flattened fins and internal spiral fins on its outer and inner surfaces, with a turbulence generator installed on the inner surface to enhance the turbulence of the fluid flow and improve heat transfer efficiency.
It significantly improves the heat transfer coefficient of the heat exchanger, with a gain of 15% to 30%, and expands the applicable range of working fluids, especially performing well under low temperature and low flow characteristics conditions.
