Heat Conduction and Convection ThermoFlux – 7106

Heat Conduction and Convection ThermoFlux – 7106 is a laboratory apparatus for fundamental experiments on heat conduction and convection using six interchangeable metal cooling fin samples of different materials and lengths.

Two long samples (copper, steel; 154 mm, 48.4 cm²) and four short samples (copper, aluminium, brass, steel; 104 mm, 32.6 cm²) are heated at one end by a 30 W heater (temperature limit: 160°C). Six continuously adjustable fans (max. 40 m³/h, 14,400 min⁻¹, 8 W each) provide forced air flow for free and forced convection comparison.

Eight temperature sensors cover -100 to 400°C. Flow velocity is measured 0 to 10 m/s. Heating power is controlled 0 to 30 W. Microprocessor-based instrumentation is fully integrated in the housing. Temperatures, heating power, and air velocity are displayed and controlled via software. Optional DAQ software in the National Instruments LabVIEW environment supports PC-based data acquisition on any Windows system.

Supplied by SCIENTICO India with an instruction manual.

The Heat Conduction and Convection ThermoFlux – 7106 is a laboratory apparatus designed for basic experiments on heat conduction and convection, two of the three fundamental forms of heat transfer. Six interchangeable metal samples, each functioning as a cooling fin, are heated at one end and dissipate heat through conduction along their length and convection to the surrounding air.

Six fans below the sample provide continuously adjustable forced air flow, enabling comparison between free convection with still air and forced convection with flowing air. The effect of different materials and different sample lengths on heat transfer can be directly compared. Microprocessor-based instrumentation is integrated into the housing; heating power and fan speed are controlled and displayed via software.


Product Overview

The Heat Conduction and Convection ThermoFlux – 7106 centres on six metal samples: two long samples (copper and steel) with a heat-dissipating length of 154 mm and a heat transfer area of 48.4 cm², and four short samples (copper, aluminium, brass, and steel) with a heat-dissipating length of 104 mm and a heat transfer area of 32.6 cm².

Each sample is placed on a heater rated at 30 W with a temperature limit of 160°C. The sample is heated at one end; heat is conducted along its length and dissipated to the environment, replicating the behaviour of a cooling fin. Six fans with a maximum flow rate of 40 m³/h, nominal speed of 14,400 min⁻¹, and a power consumption of 8 W per fan provide adjustable forced air flow around the sample, enabling heat conduction and convection experiments under both free and forced convection conditions.

Eight temperature sensors measure temperatures across the range -100 to 400°C. Flow velocity is measured from 0 to 10 m/s. Heating power is measured and controlled over 0 to 30 W. All measured values, including temperatures, heating power, and air velocity, are displayed in the software. The integrated microprocessor-based instrumentation requires no additional external devices or error-prone wiring. Optional DAQ software in the National Instruments LabVIEW environment enables PC-based data acquisition on any Windows system.

Construction and Design

The Heat Conduction and Convection ThermoFlux – 7106 is built around a heater on which interchangeable metal samples are placed. Each sample is heated at one end. Heat is conducted along the sample length and dissipated to the surrounding air, replicating the behaviour of a cooling fin.

Six interchangeable samples are provided: two long samples (copper and steel) with a heat-dissipating length of 154 mm and a heat transfer area of 48.4 cm², and four short samples (copper, aluminium, brass, and steel) with a heat-dissipating length of 104 mm and a heat transfer area of 32.6 cm². This range of materials and lengths enables direct experimental comparison of heat conduction and convection performance across different geometries and thermal conductivities.

Six fans are positioned below the sample. The fans deliver a maximum flow rate of 40 m³/h at a nominal speed of 14,400 min⁻¹, consuming 8 W each. Fan flow rate is continuously adjustable, conveying air flow evenly around the sample for both free convection (still air) and forced convection (flowing air) experiments. The heater is rated at 30 W with a temperature limitation of 160°C.

Eight temperature sensors cover the range -100 to 400°C. Flow velocity is measured over 0 to 10 m/s. Heating power is controlled and measured over 0 to 30 W. Microprocessor-based instrumentation is fully integrated into the housing, eliminating the need for additional external devices or error-prone wiring. Temperatures, heating power, and air velocity are all displayed via the software interface.
