Thermal Conductivity Experiment
(TE 19)

1

The Thermal Conductivity Experiment (TE19) is in two parts: 1) A base unit with a Peltier cooler, a vacuum gauge, and a moulded glass dome (vacuum vessel). 2) A separate control module, with heater and cooler controls and a multiline display. It also includes a connection for TecQuipment’s optional VDAS® and a suitable computer (not supplied) for automatic data acquisition.  Included with the equipment are specimens of different metals. Each specimen has a small resistive heater at one end, the other end clamps to the cooler of the base unit.

Concentric Tube Heat Exchanger (TITC)

EDIBON’s Concentric Tube Heat Exchanger (TITC) allows for the study of heat transfer between hot water flowing through an internal tube and cold water that flows through the annular area lying between the internal and the external tubes.

Computer Controlled Heat Transfer Series (TSTCC)

2

Bench-top unit to study the principles of linear heat conduction and to allow the conductivity of various solid conductors and insulators to be measured. It is given with interchangeable samples of different materials, different diameters, and different insulating materials that allow demonstrating the area effects, the conductivity, and the combinations in series in the heat transfer process.

Free and Forced Convection

The bench-mounting equipment includes a vertical duct that holds the chosen heat transfer surface and all instruments needed.
The equipment includes three different common heat transfer surfaces:

• A Flat Plate
• A Pinned Surface, similar to a tubular heat exchanger
• A Finned Surface, similar to the fins on air-cooled engines or electrical heat sinks. Each surface has its own built-in variable-power electric heater. Students choose which surface they need to test and fit it to the duct using simple fixings.

Heat Conduction Trainer
(WL900)

1

With the G.U.N.T. WL 900 Heat Conduction Trainer, the basic laws and parameters of stationary and non-stationary heat conduction are determined experimentally. To this end, a cylindrical, metallic test specimen is installed between a heat source and heat sink. The temperature characteristic of the test specimen
can be measured by a series of lengthwise distributed temperature measuring sites.

Radiation Heat Transfer

1

The equipment has two parts; an aluminum Experiment Frame and a Control Box. The frame holds all the experiment parts and allows the user to slide the parts along easily for experiments of transfer over distances. The Control Box contains the electrical controls and displays of the measured readings. The user fits different parts to the frame to measure the radiant transfer from light and heat sources. The heat source uses a variable low-voltage electric heater on a flat plate, creating a black body heat source of variable temperature. A thermocouple measures the heat source temperature. A moveable thermopile measures the heat radiation from the heat source at varying distances. 

Natural Convection & Radiation Apparatus

2

This device gives students an opportunity to check and test the rate of heat transfer, whether by natural convection or radiation at different pressures or in a vacuum state. This device also shows the differences between radiation and natural “free” convection and also allows students to know the emission characteristic from the surface and verify the equation of Stephen Boltzmann.

Thermal Conductivity Apparatus

Heat transfer is transmitted from one point to another in three ways: conduction, load, and radiation. This device allows testing the rate of thermal conductivity using five different materials used in construction operations.

The combined module of radiation and convection

1

The combined module of radiation and convection from EDIBON S.A. studies the variation experimented by the local heat transfer coefficient around the surface of a horizontal cylinder when it is subjected to a forced and free convection. The equipment is divided into two parts: the forced or free convection unit and the radiation unit.
