Peltier and Seebeck Effect Manufacturer,Supplier and Exporter in India
Product Code : EL-VATP-11376
The increasing need for smaller and more portable electrically powered equipment has produced a need for low maintenance, smaller and more portable cooling. To satisfy this need, manufacturers now use solid-state thermoelectric devices in computers, portable refrigerators and cool boxes.
The Peltier and Seebeck Effect demonstrator shows how one of these devices work and tests its performance when connected in a choice of two modes:
Heat to electricity for power generation when used in Seebeck mode – often used for thermoelectric generation and given the acronym TEG.
A switch allows tests with and without an electrical load.
As an electrically powered heat pump when used in Peltier mode.
Often used in thermoelectric cooling and given the acronym TEC.
A variable voltage supply controls the electrical power into the device.
Students then learn to analyse its performance in both modes, analysing several factors including coefficient of performance (COP) and energy balance.
For the Seebeck tests, the equipment uses an external cold water source and variable power electric heater to create a temperature difference across the device. The device then converts this into an electrical potential difference (voltage).
The load allows generated power to flow and be measured for a range of applied temperature gradients.
This allows assessment of the device performance over a range of temperature gradients and electrical power inputs.
A hand-operated valve allows the user to change the water source without the need to reconnect pipes.
Students need no tools to do the experiments.
For the Peltier tests it also uses the electric heater, but with a small water storage tank and water pump, creating a stable, fixed-flow water supply.
A calibrated vessel allows students to measure the fixed water flow accurately, for calculation of the heat pumped at the cold side of the device.
Thermocouples measure temperatures near to the surface of the device and at the inlet and outlet of the water circuit.
Clear, multiline digital displays show all temperatures and electrical measurements around the device, such as voltage, current and power.
