Description

Technical Field

[0002] Tube-fin heat exchanger is a device that increases the heat exchange area by adding fins to the outer surface of the base tube. These fins are usually made of metal materials and have excellent thermal conductivity. When the hot medium (such as steam, hot water, etc.) flows through the base tube, its heat is transferred to the fins through the base tube wall, and then the fins transfer the heat to the cold medium (such as air, water, etc.). Due to the presence of the fins, the heat exchange area per unit volume is greatly increased, thereby improving the heat exchange efficiency.
