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
• Bedplate 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

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.
• 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

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 two or more optional heat exchangers have been bought)
