LT-HT106 Radial and Linear Heat Conduction

The Labtronic Radial and Linear Heat Conduction apparatus is an advanced training tool designed to explore the principles of heat transfer through conduction in both linear and radial configurations. This unit is divided into two distinct modules: the linear heat conduction unit and the radial heat conduction unit.

Linear Heat Conduction Unit:

• The linear heat conduction module is composed of three segments:

1.     Heating Section: A brass segment heated by an integrated electric heater, equipped with three temperature sensors to monitor temperature variations across the heating zone.

2.     Cooling Section: A brass segment cooled by running water, also fitted with three temperature sensors to track temperature changes within the cooling area.

3.     Intermediate Sample Section: A removable sample placed between the heating and cooling sections, featuring two temperature sensors for precise measurement of temperature gradients within the sample.

The sections are co-axially aligned within plastic housings to minimize heat loss, and secure clamps ensure the segments are held tightly together during operation.

Radial Heat Conduction Unit:

• The radial heat conduction module includes a brass disc with an electric heater located at its core. The disc is insulated and water-cooled around its circumference to facilitate the study of radial heat distribution.
• Six thermocouples are strategically placed at varying distances from the center of the disc to record temperature profiles across the radial plane. These measurements provide insights into the temperature distribution and heat flow characteristics in a radial system.

The unit is designed with user convenience in mind, featuring adjustable water flow control via a manual valve. The flow rate can be measured manually or with an optional flow sensor.

Software Integration:

• The system is supported by specialized software for recording and processing measured data, enhancing accuracy and reducing potential for human error.

• Demonstration of Heat Transfer: Analysis of both linear and radial conduction.
• Thermal Conductivity Calculation: Measurement and calculation of the thermal conductivity of various solid materials.
• Temperature Distribution Analysis: Investigation of temperature profiles within solid bodies.
• Fourier’s Law Application: Application of Fourier’s equation to describe heat exchange between solid materials.
• Contact Surface Analysis: Study of temperature differences during conduction across contact surfaces between identical or different materials.
• Temperature Curve Plotting: Drawing temperature curves relative to distance in both linear and radial configurations.
