By using a multi-leaf structure for the inner pipe cross-section of the double pipe, the heat transfer area increases and the heat transfer rate improves!
The "high-efficiency heat exchanger" is a double heat exchanger developed to solve the shortcomings of conventional double-tube heat exchangers, using a newly developed "multi-leaf heat transfer tube." By making the inner tube of the double tube multi-leaf shaped, the contact (heat transfer) area with the fluid flowing on the outside is significantly increased without increasing the flow path cross-section. As a result, the heat exchange efficiency of the heat exchanger has been improved to more than twice that of conventional models. 【Features】 ■ Larger heat transfer area compared to round tubes, enabling miniaturization and weight reduction ■ Various cross-sectional shapes can be formed using the pull-out processing method (thin diameter and thin wall are also possible) ■ Both ends are round tubes, making connection for piping easy *For more details, please refer to the catalog or feel free to contact us.
