U-tube heat exchanger

A U-tube heat exchanger is a device used to transfer heat between two fluids without them mixing. It consists of a U-shaped tube through which one fluid flows, while another fluid flows around it in a separate space. The design allows for efficient heat transfer: one fluid can be heated or cooled by the other. U-tube heat exchangers are commonly used in various industries, including HVAC systems and process engineering, to improve energy efficiency by recycling heat. Their compact design and effectiveness make them popular in applications where space and energy conservation are important.
