Understanding the Double Pipe Heat Exchanger: Design, Function, and Industrial Applications

In the realm of industrial thermal management, heat exchangers play a pivotal role in transferring heat from one medium to another efficiently. Among the various types available, the Double Pipe Heat Exchanger stands out as one of the most fundamental and widely used designs. Its simplicity, flexibility, and effectiveness make it ideal for small-scale to medium-scale industrial applications, particularly where space constraints and varying flow rates are involved. What is a Double Pipe Heat Exchanger? A Double Pipe Heat Exchanger consists of two concentric pipes — one smaller pipe nestled inside a larger one. One fluid flows through the inner pipe while the other flows in the annular space between the inner and outer pipes. The thermal energy is exchanged between the two fluids across the wall of the inner pipe, allowing either heating or cooling of the process fluid. This configuration can be arranged in two flow types: Parallel Flow: Both flu...
