Construction and Design

The Linear Heat Conduction Module ThermoFlux - 7049/1 is assembled on a bench support frame and built around two primary sections: an insulated brass heated end and a brass cold end, each 25 mm in diameter. The heated end houses a 100 W electric heater with power controlled and measured through the Heat Transfer Service Unit. The cold end is connected to laboratory tap water for continuous cooling. Three thermocouples are embedded at equal intervals along each end section, providing six fixed measurement points across the heated and cooled boundaries.

Four interchangeable intermediate test sections are supplied for use between the two end sections. Three sections share a common 25 mm diameter and 30 mm length: a brass section with an integrated temperature sensor array, a stainless steel section, and an aluminium section. A fourth brass section with a reduced diameter of 16 mm and 30 mm length is included for cross-sectional area experiments. Any section is clamped between the heated and cold ends using the same mounting arrangement. Thermal paste is supplied to minimise contact resistance at interfaces where required by the experiment.

This linear heat conduction module accommodates nine thermocouples in total, all connecting directly to the Heat Transfer Service Unit for real-time digital temperature display. The assembly supports both single-material and composite wall configurations, allowing direct comparison of thermal conductivity across brass, stainless steel, and aluminium, as well as investigation of contact resistance, poor conductors, and unsteady-state thermal behaviour. Operation requires the Heat Transfer Service Unit ThermoFlux - 7049.

Frequently Asked Questions

Q1: What interchangeable test sections are supplied with the ThermoFlux - 7049/1?
Four test sections are supplied. Three share a 25 mm diameter and 30 mm length: a brass section with integrated temperature sensor array, a stainless steel section, and an aluminium section. A fourth brass section with a reduced diameter of 16 mm and 30 mm length is included for cross-sectional area variation experiments.

Q2: How many thermocouples are included and where are they positioned?
Nine thermocouples are included in total. Three are embedded at equal intervals in the heated section and three at equal intervals in the cold section. Additional thermocouple positions are located within the interchangeable test sections. All nine connect directly to the Heat Transfer Service Unit for digital display.

Q3: What experiments does this linear heat conduction module support?
The module supports eight experiments covering steady-state and unsteady-state conduction, Fourier Rate Equation application, composite wall Overall Heat Transfer Coefficient determination, thermal conductivity measurement of metals and poor conductors, contact resistance demonstration, cross-sectional area effects on temperature gradient, and engineering application exploration.

Q4: What is the purpose of the thermal paste supplied with the module?
Thermal paste is used at the clamped interfaces between the heated section, the intermediate test section, and the cold section. It minimises contact resistance at material interfaces, ensuring reliable and repeatable heat flow measurements during conduction experiments.

Q5: Is additional equipment required to operate the ThermoFlux - 7049/1?
Yes. The Heat Transfer Service Unit ThermoFlux - 7049 is required for operation. It controls and measures heater power, connects to all nine thermocouples, and displays temperature readings on its digital panel meter.
