Concentric Tube Heat Exchanger
Model Number: TD1360A
Demonstrates how heat transfers between hot and cold fluids in a simple concentric tube design.
Overview
Shows how a simple concentric shell and tube heat exchanger works.
This is the simplest of the optional heat exchangers. It has two tubes, one inside the other. One tube carries hot fluid, the other carries cold fluid. Heat transfers between them. TecQuipment’s heat exchanger is in two equal parts joined by intermediate pipes. This allows two extra measurement points at the midpoint (plus the standard four points at the connectors). This gives more useful experiment results, to show more clearly how the fluid temperatures change during heat transfer.
The Heat Exchanger Service Module (TD1360V) provides hot and cold water to the heat exchanger and all the instruments needed to measure its performance. All fluid connections to the heat exchanger are self-sealing quick connectors for safety and simplicity. The hot and cold fluid streams have different connectors to reduce errors. Connecting the heat exchanger takes less than one minute. The heat exchanger is on a bedplate that has a clear schematic diagram showing the connections.
