The shape advantages of elliptical flat tubes are concentrated in three core dimensions: fluid mechanics performance, structural adaptability, and heat transfer efficiency, which are more scene specific compared to circular tubes and ordinary flat tubes.
1. Improve fluid flow efficiency
The streamlined design with elliptical cross-section reduces fluid resistance and energy consumption in medium transportation, especially suitable for high flow rate fluid scenarios.
The flow velocity distribution on the inner wall is more uniform, reducing the generation of eddies and lowering pipeline wear and noise.
2. Optimization of heat transfer performance
The elliptical flat tube has a larger specific surface area, which increases the contact area with the heat exchange medium and improves the heat exchange efficiency.
The flat structure facilitates tight arrangement, reduces equipment space occupation, and improves the heat transfer power per unit volume of the heat exchanger.
3. Stronger structural adaptability
A flat shape is more suitable for fitting curved surfaces or narrow spaces, meeting the compact layout requirements of devices such as automobiles and air conditioners.
Better resistance to bending and torsion, with higher structural stability than circular pipes in vibration environments.
4. Higher material utilization rate
Under the same cross-sectional area, elliptical flat tubes have a shorter circumference, reducing material consumption and lowering production costs.
The thickness distribution of the pipe wall is more reasonable, and the design can be optimized according to the stress situation to improve the structural strength.
