Description
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 Service Module (TD360) 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 bed-plate that has a clear schematic diagram showing the connections. The bed-plate fixes to the Service Module with thumbscrews.
Key features:
- One of a set of optional heat exchangers for use with TecQuipment’s TD360 Service Module
- Popular type heat exchanger, used in industry but designed for teaching
- Simple and safe to use – foolproof fittings allow students to change and connect the heat exchanger quickly and easily – needs no tools
- Clear outside casing, so students can see its construction
- Bed-plate with a clear schematic diagram to help students understand how to connect the heat exchanger
- Corrosion-resistant materials for use with ordinary clean water at safe temperatures
Learning outcomes
- Demonstration of heat transfer from one fluid to another through a solid wall.
- Energy balance and efficiency calculations.
- Demonstration of parallel-flow and counter-flow operation of heat exchangers.
- Measurement of the heat transfer coefficient, and the effect of fluid flow rates and the driving force (temperature differential) upon it.
- Introduction to the logarithmic mean temperature difference in heat exchangers.
- Comparison of different types of heat exchanger in terms of performance, size and relative cost (only if you have two or more optional heat exchangers).
