Tubular Heat Exchanger

The Tubular Heat Exchanger is a practical educational apparatus developed for studying heat transfer between two fluid streams through a tubular heat exchanger arrangement. Manufactured by Micro Technologies, the equipment helps students understand the operating characteristics of heat exchangers through direct measurement, observation, and calculation.

The apparatus is designed to demonstrate both parallel-flow and counter-flow configurations. In parallel-flow operation, the hot and cold fluids move in the same direction through the heat exchanger, while in counter-flow operation, they move in opposite directions. This allows students to compare the temperature behaviour and thermal performance of the two fundamental flow arrangements.

During experiments, temperatures can be recorded at relevant locations along the heat exchanger. These measurements allow students to plot temperature curves for both parallel and counter-flow conditions and observe how fluid temperatures change along the heat exchanger length.

Experimental temperature and flow data can also be used for the calculation of the mean heat transfer coefficient, providing a practical connection between theoretical heat transfer equations and actual laboratory measurements.

The tubular construction provides a clear demonstration of indirect fluid-to-fluid heat exchange, where thermal energy passes through the tube wall without direct mixing of the two fluid streams. This principle is widely applied in industrial heating, cooling, process engineering, refrigeration, power generation, and chemical processing.

The apparatus features a compact and accessible construction that allows easy connection to a compatible heat exchanger supply unit. Its straightforward experimental layout makes it particularly suitable for engineering students, laboratory demonstrations, practical examinations, and thermal engineering training.

FAQs

What is a Tubular Heat Exchanger?

A Tubular Heat Exchanger is an apparatus in which heat is transferred between two fluid streams through a separating tube wall without directly mixing the fluids.

What is the main purpose of this laboratory apparatus?

The apparatus is designed to study the function and behaviour of a tubular heat exchanger, including temperature variations and heat transfer performance under different flow arrangements.

Can parallel-flow experiments be performed?

Yes. The Tubular Heat Exchanger can be operated in a parallel-flow arrangement, allowing students to record and plot the corresponding temperature curve.

Can counter-flow experiments be performed?

Yes. The apparatus supports counter-flow operation, enabling comparison with parallel-flow performance.

What temperature experiments can be performed?

Students can record temperatures at different locations and plot temperature curves for both parallel and counter-flow operation.

Can the mean heat transfer coefficient be calculated?

Yes. Experimental measurements obtained from the apparatus can be used to calculate the mean heat transfer coefficient.

What is the difference between parallel and counter flow?

In parallel flow, both fluids travel in the same direction. In counter flow, the hot and cold fluids move in opposite directions, resulting in a different temperature distribution along the heat exchanger.

Does this unit require a supply system?

The experimental module can be connected to a compatible heat exchanger supply and instrumentation unit to provide the required fluid circulation, flow control, and measurement facilities.

Is this suitable for engineering colleges?

Yes. It is suitable for mechanical engineering, thermal engineering, chemical engineering, energy engineering, and heat transfer laboratories in universities, engineering colleges, and polytechnic institutes.
