Heat Exchanger and Tube

Definition and Basic Characteristics

The heat exchanger tube is the core component of heat exchangers, facilitating thermal transfer between two or more fluids. Typically manufactured from metals like stainless steel, copper, aluminum, or titanium alloys, these tubes combine excellent thermal conductivity with corrosion resistance. Their design maximizes heat exchange efficiency while maintaining structural integrity.
