What’s included in the teaching equipment for thermoelectric devices
- Mechanical assembly comprising of a high-power resistor (heater), heat exchange plates and an efficient fan-cooled heat sink. Two thermistors are used to measure the temperature on the sides of the thermoelectric device.
- Heater controller unit to vary the power supplied to the resistor. Mains powered. It shows voltage / current / power and the temperature of the heater.
- Fan controller unit to control the fan speed. Mains powered. The fan is a 4 wire Intel-spec unit and the controller allows adjustment of the fan’s speed and reads back the tacho frequency. The fan-side thermistor temperature is also shown on the display.
- Low-power version of the RO2 I-V tracer and at-load tester. This unit is used when the thermoelectric device is acting as a power generator.
The teaching equipment for thermoelectric devices does NOT include a power supply to use the thermoelectric device in heat pumping mode, which can be purchased through TCS. Alternatively, a power supply capable of providing at least 12V / 3A can be used.[/vc_column_text][/vc_column][vc_column width=”1/3″][vc_single_image image=”260″ img_size=”medium” add_caption=”yes” alignment=”center”][vc_empty_space][ind_cta text=”Buy Teaching Equipment” btn_text=”Buy now” btn_link=”https://www.teconversion.com/product/teaching-equipment-te-devices/”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
What it is used for
The teaching equipment for thermoelectric devices can be used for the following experiments:
- Investigations of heatsinks, heatpipes, the effect of fan cooling, thermal resistances, etc. and how to model thermal circuits.
- Seebeck power generation. Plotting I-V curves, maximum power point, constant heat behaviour, changing thermal conductance of the TEG with load current, etc. Maximum temperature is greater than 100°C.
- Peltier cooling. Heat pumping, plotting Qc and CoP curves, parasitic Seebeck effect, investigating Vmax, Imax and Qmax. Minimum temperature should be limited to 3°C.
A full set of student notes and a set of demonstrator notes are available on request. They show the typical results obtained for each of the these experiments.[/vc_column_text][/vc_column][/vc_row]
