SL110.03 Shell & tube heat exchanger teaching aid equipment Heat Transfer Educational Equipment
Shell and tube heat exchangers are used in widespread use. The main advantages of this design are the large heat transfer surface and the compact design. Shell and tube heat exchangers are used in the chemical and pharmaceutical industries, in refineries and in process engineering plants.
The SL 110.03 is part of a series of units enabling experiments to be performed on different heat exchanger types. The experimental unit is ideally suited for investigating the functioning and behaviour of a shell and tube heat exchanger in operation.
The SL 110.03 is connected to supply unit SL 110 using quick-release couplings. The shell and tube heat exchanger consists of seven tubes, surrounded by a transparent outer shell. The hot water flows through the tube space and the cold water through the space in The shell. Part of the thermal energy of the hot water is transferred to the cold water. Baffle plates are used to deflect the flow in the shell in such a way as to create greater turbulence and thus a more intensive transfer of heat. Flows in a cross-flow.
Valves on the supply unit are used to adjust the flow rates of hot and cold water. The supply hose can be reconnected using quick-release couplings, allowing the flow direction to be reversed. This allows cross parallel flow or cross counterflow operation. For measuring the inlSTand outlSTtemperature are located at the supply connections on the SL 110.
During experiments, temperature curves are plotted and displayed graphically.
