LT-HT101 Heat Conduction in Metals

The Labtronic Heat Conduction in Metals unit is specifically designed to study the principles of heat transfer by conduction across different metallic specimens. The apparatus includes eleven metal samples, each tested for its thermal conductivity using an electric heater as a heat source and a Peltier cooler as the cooling source.

A specially designed mechanism allows for precise experimentation, minimizing the gap between different metal specimens through the application of thermal paste, ensuring accurate and reliable readings. Differential temperatures between the heated and cooled areas are measured using high-precision temperature sensors. These values are then transmitted to dedicated software, which not only records and processes the data but also helps reduce human error, ensuring high accuracy in all measurements.

• Demonstration of Heat Transfer by Conduction: Visualize and understand how heat is conducted through various metals.
• Calculation of Thermal Conductivity: Measure and calculate the thermal conductivity of each metal specimen.
• Thermal Resistance Analysis: Calculate thermal resistance and its implications on heat transfer.
• Material Comparison: Investigate how different thermal conductivities influence heat transfer between metals.
• Length Effect Demonstration: Study the effect of specimen length on heat transfer efficiency.
• Steady-State Analysis: Examine the time dependency until a steady state of heat transfer is achieved.
