(Shell and Tube Heat Exchanger)

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:

•  It is a large tube (shell) which surrounds several smaller tubes (a bundle).
• One fluid passes through the shell, and the other fluid passes through the tube bundle, therefore transferring heat. Baffles around the bundle help to create a turbulent mixed flow.

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)
