A hairpin heat exchanger is a type of tubular heat exchanger designed with two or more tubes bent into a U-shape, resembling a hairpin. This configuration allows efficient heat transfer between two fluids—one flowing through the inner tubes and the other through the shell side. The design supports counter-flow or parallel flow, ensuring excellent thermal performance even under high-pr... https://www.unitedheatexchangers.com/blog/what-is-a-hairpin-heat-exchanger/
